Hello Mr. Beaty !!
First of all let me wish you a Happy New Year 2009 !!
I found your article to create a disgustoscope on the web.
I do have to tell you, that in 1988 already manufactured caleidoscopes in the way of your disgustoscope already existed. They called it Octoscope (or something like this).
I was strolling around mid eighties, definetly not after 1988 in the city of cologne, where i was visiting some friends of mine. And I found a shop called TRAUMSTERN. A crazy little psychodellic shop runned from some, this is what i think some old hippies (the way they look like and what kind of stuff they are selling). This little shop did have a lot of fascinating caleidoscopes. Kind of I never saw before. And this Octoscope, what I bought was produced/manufactured from Apres la Pluie, 4950 France (thats what is printed on the tube, which covers inside the octoscope, which is made out of metall, with inside, sure you know, the three mirrors and a lense at the end).
I and all the other people, looking through it, still have a lot of fun with it and I do agree that you have to use it outside. Better reflections.
After all of this years it is a little damaged (but still working), thats why I researched on the web to find this guy/artist/factory who created this. I guess I have to take care about it myself to get it fixed and cleaned up.
If you have any questions please feel free to contact me.
Hi, after watching your video on how to make a generator, i decided I'm going to make the fancier one. At 7:17 of your video you were tightening something on the top corners of the plastic, i was just wondering what those were and if i needed them.

Your article on how transistors "really" work was a godsend to me. Since I was first interested in electronics (some 35 years ago) I've always wanted to know HOW & WHY something works...not just memorize formulae and schematics and go from there. That article helped a lot. Great work!

Your article "Incandescent Bacteria" describes hyperthermophile and hyperbarophile (a word I just made up meaning "high pressure-loving") bacteria that do odd, for bacteria, things like glow in the blue and UV parts of the spectrum. Suppose they do so for the same reason that "ordinary" life glows in the IR part of the spectrum; the extremophiles' metabolism runs so fast that the blue and UV photons they emit are their equivalent of "body heat"? By the way, have you considered such lifeforms as the cause of the anomalous high-energy optical output of sonoluminescence in water? Considering the anomalous light output only comes at the pressure peak of the effect, it would make sense if the little bugs' spores were present everywhere in water but only come fully alive under the severe pressure transients induced by sonoluminescence. If their metabolism indeed runs much faster than does that of ordinary life, they could experience many life cycles in the duration of a single pressure transient. It might be interesting to do a bioassay of the water used in a sonoluminescence experiment before and after running it for a while.

Bill, I need to have some philosophical discussuion with you involving Lichtenberg figures and their potential uses. Bert doesn't want to hear me. I know that you are open minded and I think we could rise above the common mode of obstacalized thinking and really look at this phenomenon from outside of the box.

Bill, just wanted to say Your explanation of how transistors really work was Great ! I've been searching for answers...trying to figure it out and stumbled across this site. I do have a question/misunderstanding. It seems that everyone, including you say that a transistor is, or can be an amplifier. I still find this difficult to comprehend. It seems that even though the transistor is opening a gate with a small voltage, in order to let a large current flow through it, The transistor in and of itself is still just a switch. Without the other power source at the collector/emitter, supplying the voltage and charge flow, the transistor is not actually amplifying anything ??? To me an amplifier would be a device, lets say a magical water pipe that I could put water in one end of it at the rate of 1 gal per minute, and it would come out the other end at 10 gal per minute ??? Now if I have a pipe with a valve and my hand acts as a devive to vary the flow rate per minute from 1 to 10 I wouldn't call my hand or the valve an amplifier ? But it seems that with transistors that what people say ??? I'm kinda lost ??? If anyone can give some explanations I'd appreciate it. Thanks, Jeff

Sincere thanks from another "Babylonian". The maths outputs can always be had by trial and error, once the physics makes sense. But to have to find the physics by trial and error is to forever re-invent the wheel. Common sense explanations like yours are what truly allow us to see further everyday, by standing on the shoulders of those who DID find the physics by trial and error. most gratefully Robert

Regarding the nanoammeter described on the following page: http://amasci.com/emotor/nanoamp.html I've got a use for this nanoammeter. I'm a mechanical engineer and I work with electromagnetically actuated and sensed micron scale devices. The output signals are in the 10s of picoamps to 10s of nanoamps range. What I'm not clear on with the setup is which comes first the ammeter panel or the voltmeter. If anyone can help out with a clear description of the order of things I'd sure appreciate it. If it's easier to email a simple sketch (MS Paint?) then that would be great as well. Many thanks in advance! Fred

I live in North America, but I am going to be spending a year abroad in Israel. I would like to bring my laptop with me to use while I'm there, and since they have different plugs, I bought an adapter (not to be confused with a converter, my computer will be running on the Israeli 220V instead of the North American 110V). The thing is, this adapter has only two slots, while my laptop plug has three. I mentioned this at the store, and they assured me that it would be fine to plug in the two prongs and let the third stay outside. Logically, this should work as far as charging my laptop, but is this safe for both me and the device?

I could really use your help at any time before December 6th because i wish to use your simple electric generator design for my freshman science fair project. First of all I would like to know what kind of sewage pipe did you say i could use on the plexi glass version and how do i even constuct the plexi glass version. Also i would like to make a larger scale model of the generator using super magnets but i dont know where i could get a custom made super magnet the size i want. and one more thing, where can i get a lot of solenoid wire and i mean a lot(maybe over 600 turns under 5000?). Thank you and keep up the good work. because of you physics seems fun :).

this is a response to your "Threadlike electric wind" post. what you have created is actually a tool used by particle physicists called a cloud chamber. it is used to visualize subatomic particles. because the dry ice is so cold, you have air that is supersaturated with water (kind of like a cloud). in a cloud, raindrops form around what is called the nucleation point. it is important to note that usually this consists of small dust particles, but raindrops will also nucleate around subatomic particles, such as electrons, positrons, protons, and any other particluate-based radiation, including alpha and beta particles. when these drops form, they pull water vapor out of the air, leaving a 'contrail' that you can see. these are the 'threads' (this is why your negative ion generator was so effective) (note that these particles are passing through or around us all the time) a more effective cloud chamber can be made by placing a glass tank on a layer of dry ice, and draping an alchohol soaked felt strip around the top of the inside edge. the dry ice helps to supersaturate the air with alchohol. cover the tank, and wait a few hours for it to get really cloudy on the bottom. interesting experiments to try include using ur neg-ion generator to shoot particles around a magnet (the magnet should cause the normally straight path of the particles to veer off to one side. enjoy!

Bill re your article of telsa's big mistake it seems that you where not far off the mark with your thoughts please see below an actual result of this theory. Schematic of the experimental setup. A is a single copper loop of radius 25 cm that is part of the driving circuit, which outputs a sine wave with frequency 9.9 MHz. S and D are respectively the source and device coils referred to in the text. B is a loop of wire attached to the load (light bulb). The various srepresent direct couplings between the objects indicated by the arrows. The anglebetween coil Dand the loop A is adjusted to ensure that their direct coupling is zero. Coils S and D are aligned coaxially. The direct couplings between B and A and between B and S are negligible.
Using self-resonant coils in a strongly coupled regime, we experimentally
demonstrated efficient nonradiative power transfer over distances up to 8
times the radius of the coils. We were able to transfer 60 watts with 40%
efficiency over distances in excess of 2 meters.
Bill, I have Just read your article on Tesla's big mistake, and wow what great insight. Could you tell me if this is related in any way to Scalar waves, which many have postulated is the radiant energy Tesla called the ether

I have spent about the last 20 years trying to make a static electricity machine with only intermittent success: because I don't understand how they work! Anyway I have managed to distil one idea from of all that, which is that you can make a belt-pulley out of a bulbous plastic pop bottle. You can drive it with a hand-held battery power drill by attaching a screw to the pop bottle lid which you can put in the drill chuck. And whoever is holding the drill can stand on insulating foam & tension the belt manually, also wipe something on the moving belt with his/her free hand. But I just don't understand the physics! Knew for certain I understood it at school but now am a sadder & wiser man. Can you help?

Hi I am commenting about your Traffic Wave article. I am from Australia. I have been driving with what I call an "Air Buffer/Gap" (2 or more car gap) for a good many years. There are 2 reasons for it. 1: I drive older cars and I do not trust the brakes. I like to leave room just in case something goes wrong. 2: I do not like stopping or gearing down into first. The car does not like first gear either. I drive on city roads like the car is a ship, if I see red-lights (traffic or cars or any other possible hazards) I slow down so when I get to that point, the road is clean and I can keep the vehicle moving. I find it refreshing that you have a web-page about traffic flow. Especially the video where you demonstrate good driving. There is a driving school in my building and I am going to recommend your web-page to them. You sir, may have influenced a generation of calmer drivers. I would buy you a drink but I fear a Postie would get to it first.

I just read the article about the woman and her daughter "hearing" radio frequenciesand it was a breath of fresh air to find that my siblings and I are not alone. We also have the ability to sense if a television is on without the volume on or seeing it. Some television signals are stronger than others to the point that I can't even stand it being on. Most televisions are tolerable but will cause me a headache after awhile. I never knew anyone else, besides my siblings, that was able to do this. That left me feeling like a freak. I would explain it as a painful fuzziness in my head. It's comforting knowing that there are others.

I've recently picked up electronics as a hobby, and some some other information on the net confused me about this issue. On a completely unrelated note, I read in your little bio that you're fond of "wacky" music. I heartily recommend a band/guy called Lemon Demon (lemondemon.com). He has a pile of sample mp3s on his site (specifically, you might try "Kitten is angry").

About three weeks ago my roomates sister was at our house doing her hair before work. She called him crying, and said that it sounded like a truck had driven through our house. The whole house vibrated, and she thought it was an earthquake. This lasted about 20-30 seconds. Our surrounding neighbors rushed over to see what had happened. One reported that he saw our whole roof shaking. My roomate rushed home to inspect the water heater and any other suspect areas. Everything was perfectly normal. I was intrigued as to what the source was, speculating that the hot day caused our 90 year old house to suddenly settle in some wierd way. Nothing happened to any of our neighbors houses. I havn't thought about it in a couple weeks, until I came across an online article in Fortean Times today. I then realized how many people actually have heard this. Our case seems to be one of the most intense i have read about. It seems stronger than the Taos hum. We live on a large hill in Tacoma, WA. There is a railroad about a half mile away in a valley, a few hundered feet lower than our house. We also live within a mile of Commencement bay. Has anyone every felt a localized earthquake like this?

Bill, Thanks for introducing me to hand drawn holography. I have made several "holograms" now, and some of them look pretty good. Perhaps due to lack of patience, I had trouble implementing your solution to the problem of scratches obliterating each other. I found an alternate approach that I'm sure you're already aware of. I have found that the under side of the scratch works about as well as the upper side in producing a spot of light. Using thin, clear material (I'm using .06" thick polycarbonate), you can divy up the scratches so that some are made on the upper surface and some on the bottom surface of the plastic sheet. By planning, you can thus reduce some of the obliteration that goes on when you have a lot of points. For example, if you are recording a word, you can put every other letter on the back surface. By using this same idea, you can make a two "color" hologram. Say the thin plastic sheet is tinted blue. The scratches on the upper surface will produce white points of light while the scratches on the bottom surface will produce (somewhat dimmer) blue points of light. The thinness of the material minimizes any refractive displacement. Thanks again. Don

Just read the article "Cognitive Processes and the Suppression of Sound Scientific Ideas" by J. Sacherman 1997. I was thrilled to see in print the ideas he expressed on the issue of scientific community being very closed to new ideas or challenges to popular and accepted theories. It was dissappointing to see the references to Darwin and evolution included in the arguement, when there is so much clear, observable science that contradicts the theory, and yet even in the article, the 'theory' is supported as fact by the author. Why do you think the scientific community today is so opposed to solid science that refutes evolution? Why are any facts that raise serious questions to the theory thrown out as 'bunk' or the scientist who put these ideas forward dismmised as 'fanatics'?

On my site www.freeornottobe.org there is a simplified explanation of "How Energy Works" which explains every mysterious phenomena in physics that I know of using Geometry. It is the culmination of eight years of research and I believe it is an accurate and simple way for any one to figure out how to build anything by understanding how the laws of nature work using Geometry. I really need intelligent people to give me constructive feedback, and I really want to take part in developing gravity and energy generating technologies. Please check it out at www.freeornottobe.org, and email me: firstname.lastname@example.org

I am ABD in pure mathematics working for the Army Corps of Engineers on devising an Arc Flash Protection Program and found your site very useful. You made me sad, however, when you described math as a "useless tool" and "a bunch of recipes" , a "crutch" for those who do not think like the Babylonians. True math has nothing to do with equations and recipes, it is about understanding the properties that are important and relevant to a particular problem, abstracting them, then connecting them to other mathematical objects. Equations and Formulas appear sometimes in lower mathematics where coordinate systems may arise as a consequence. The formulas are only there to make the physicists and engineers happy. I don't know if I speak for all mathematicians, but the ones I know, love to find connections and figure out why the relationships work the way they do. Once they see the connection, they would just as soon throw out that problem and go to the next one. I hate having a board full of equations. It is the explanations of what they mean, and how they connect to the objects we are studying that are really important. I am sorry for the epic, and I'm sure you will never read this, but I wanted to defend the field I fell in love with when I was 4 years old.

Good Evening Sir. First of all, I want to say you ?Thanks?, for giving me, your costly time. Sir I don?t want to waste you time and I don?t want to disturbed you. If I disturbed you, then I say, ?I am sorry, Sir? My self introduce to you as Balram Tiwari, student of BSc 3rd year in G.N.KH.College, in Yamuna Nagar, in Haryana, in India. Sir 3 year ago I wrote a research paper on the topic Origin of Gravitation by Nebula Hypothesis. I had done my best to publish this paper to Science Magazines. But it is my bad luck that no one helps me for publication of my research paper, in India. I don?t know my paper is correct or not. But I know that my research paper is based upon Laws of Physics, which is made by Sir Isaac Newton. No laws of physics are invalid in my research paper. Sir I had spent 3 year in study my research paper by my imaginational universe. After it my research paper could not made me a scientist. But my research paper made me a mental. This is not told by me. These words are told by people that are connected with me. I read your History of Research and Development of nuclear gravitational theory and after study your work on gravitation and your Website, I decided to take your help. I am sending you this latter by hopping that, you can help me. I need your help urgently. I always considered ?Sir Isaac Newton? as my ideal. I always trying to becomes like him. Sir my last wish of my life is to search origin of gravity in universe, by Sir Isaac Newton method. That?s why I want your help. But before this, I want to tell you some thing about me. I am a poor student of BSc. I had got 47% in 1st year; compartment in second year and for 3rd year, reappearing for exams paper. I belong to a poor family and I have no capacity to clear even entrance exams also. Because I am a poor student of science as shown by my results. I have no capacity to clear my BSc Class as I belong to a poor family in which no one at job. Only I am at job in a private school at 10 dollar per month. India is a poor country and job and study facility are only for middle class family and reach family. I want to make my self like a famous scientist. In Japan, a student of BSc. got Young Scientist Award 2005, for the research for DNA formation. But In India it is impossible. But my Last wish of my life is to make my self a brilliant scientist. I don?t know my wish is fulfill or not. If possible please help me. I want your support. In India, I got only abusing of people, mentally pressure and wondered person. I don?t want to take your help freely and with out competition. You can take my online interview about my study and knowledge. I become your servant and serve you till my death. You should check my knowledge. After it, if I able for you then give me your teaching support. other wise you can say me ?No?. I have no money, for come to your country, I pay all fees and all price, by part time job. And work for you as servant. I think that, no body can take risk about me. If I am at the post of you, I also behave as you behaving with me after study this email. Sir please doesn?t take any tension about me. I don?t want to disturb you. I told you every thing truly about me as ?Honesty is the best policy?. Sir no one can understand my heart feeling and my struggled full life. Sir please helps me. I need your help urgently. Otherwise my life and future are destroyed in this hell country. I am just waiting for your email. Sir please replies me, weather you say ?Yes? or ?No?. Only one word by you can change my life.

I have for some time been a happy reader of these various pages, and grateful for the excellent clarifications of electrical theory. I've recently got a bee in my bonnet about building a simple but modern steam engine, and quickly discovered that generating the steam is the tricky part. I'd like to generate the steam on an instantaneous demand basis - being easier to control and using probably fewer weighty parts - so I thought maybe microwave flash boiling would be worth a try. I noticed Bill's comment that 10 GHz was closer to the "water opaque" frequency, confirmed this for myself at atmospheric research pages, so started looking for cavity magnetrons (or SOMEthing) to generate around a kilowatt of RF at in the X-band. (It's OK, I'm a VHF and UHF radio tech with over 40 years of experience, no longer working in that field, but I won't hurt myself.) My question, after that rambling intro, is this: how does one generate that much power at that frequency? I'm stymied; I can find no useful info through google; it's almost as if the web has been purged of such info. Maybe it has? Anyway, can anyone help with this? I thought at first that I could just buy a device and power it up, and that my biggest problems would be pulse width and duration for effective steam, and figuring out what to use for the microwave window into the combustion chamber/boiler. But I can find no such device. If anyone can point me towards one, they could be instrumental in helping get the first steam aeroplane into the air since Bessler in the 30's!

Hi - Excellent site! Enjoyed your electric charge detector article. But not sure about the statement "it really takes no energy to turn off the FET". Surely the electrostatic field results in a force on the electrons, which move aside as a result. Force x distance moved = work (energy expended). The net electrostatic potential is slightly reduced as the electrons are now further away from the gate. Or am I misunderstanding this?
[To a first approximation, an FET gate is a capacitor, and capacitors use no energy. Yes, you can store energy in them, but you get it all back again. So, it takes energy to turn off the FET, but that energy is returned when you turn the FET back on again. (Second approximation: it's not a perfect conductor, so the tiny currents in the Gate circuit do have tiny losses because of heat. -billb] Cheers, Laurence.

Good job on your web site ! I have had a blast lookin through and its nice to see some of that good ol fashion hardware hacking! I am a newby to this site and have always been interested in HV Tesla and anything that vibrates. I am an electronic musician and have been curious of phenomena wilst tinkering with everthing plugged in ~ guitar strapped on and on concrete with bear feet! Thank god i survived! But that was when i was a kid and i see the importance of passing survival to the new curators and caretakers of this amazing bubble we live in. So now i see an emerging brave new comunications frontier and the window is about to bust wide open. Somehow when we play with are toys, thats when the REAL science shows up and some of us notice the the guy on the other side of the fence! I think with computers,music, and high votage we can relearn the lost neuro net we had when we were living in the caves and in Mesopotamia! Let us play and teach the way to our future. I believe that this very essence of self and our relationship with our mother earth is about to invent the solution and it will be through the clever vines the bushies will never understand, nor will they enslave us anymore.

On your IR goggles, in _The Human Senses_, 2nd ed., by Frank A. Geldard (pub. John Wiley and Sons, New York), pg. 21, it is stated: "Reliable measurements of visible light, involving very high energies, have extended into the ultraviolet to wavelength 312.5 nm and into the infrared to wavelength 1050 nm. ... To see a light of wavelength of wavelength 1000 nm ... there is required a source 10 billion times as strong as that needed to see a light of wavelength 562 nm." While the phrasing seems odd to me, the context makes it clear that he is referring to the seeing with the naked eye of such light. No references (eg, to experimental reports) are given for these claims. I am also not sure whether, these claims refer to a simple binary yes/no, or if an differentiation of intensities was made by the subjects, nor if actual images were reported by the subjects. This certainly suggests, though, that with extremely bright light sources, pushing further in to the infrared than you have already tried is a possibility.

I've seen that you know the Carver Mead's "Collective electrodynamics". It's a good and new look on electromagnetic theory, very "cutting-edge". But do you know the theory of Milo Wolff, on which the Mead's book was based? It's the Wave Structure of Matter theory and it treats electrons as waves made in empty space. Here's Milo Wolff website: http://quantummatter.com/ He wrote a book explaining his theory ["Exploring the Physics of the Unknown Universe"] and recently he published part two of it, more about electronic waves, quantum physics and Schroedinger equation. BTW I've seen also that you're making use of A field [vector potential]. I very appreciate it, because in the Internet and books there are a few info about it, and it's very pity, because this field seems to be more fundamental than E and B fields. Still much students of physics I've talked have objected that in toroidal coil there is A field present and it's not directly the B field which induces the current in secondary wire. I really appreciate your Tesla articles too, because his inventions appears to be very related to A field.

I was married at 27, had my daughter at 29 and was widowed at 31. My husband had smoked for years before I met him and continued throughout our marriage. We were excited over his being appointed Press Secretary for a newly elected U.S. Senator from our state. We had moved across country from Seattle to Washington, D.C. just six-months before he became ill. Amazingly, that day in June started out like any other, except that I had agreed to pick him up from the subway station at a D.C. suburb. He had become so confused on the train that he couldn't remember which stop was his. His co-workers would later tell me that he had been acting strangely the past few days at the office (not quite like himself). The strange behavior - the doctors later advised - was due to a severe potassium depletion caused by his illness. My husband was diagnosed a few weeks later, but first had to suffer the indignity of spending a night in jail and several weeks in a psychiatric hospital while they tried to figure out what was wrong with him. It wasn't until he asked for a chest x-ray that we discovered he had a quarter-sized darkened area located toward the center of his lungs. We thought ok, now we at least knew what the problem was and (besides), people could live with one lung. We were buoyed ONLY temporarily. When the diagnosis came down it was; small cell lung cancer, inoperable and fully mytastisized. We came back home to our family and friends in Seattle, fought hard, celebrated our last Christmas together and I watched my wonderful, sweet, gentle husband try to say goodbye to his baby daughter. His Masters Degree in Journalism from Columbia University offered little help to him now. My husband died 25-years-ago this last July 4th and I still think of him at least once every day. My daughter looks astonishingly like her dad although he promised otherwise. But possibly the saddest part of this story is that my beautiful, funny, smart 28-year-old daughter, has been smoking since she was 16. I remember what went before and worry about her everyday.

I am currently in contact with REVA an electric car manufacturer in India and am helping them extend the mileage per charge. Cooperation in the USA on this is doubtful. Based on the molecular properties of water there is a way to calculate the electrical energy output that can be expected (I have tried to find but can't). Kelvin's Thunderstorm is an experiment where you can measure the actual output. However, if the experiment is reduced to its simplest form where each drop is a molecule what would be the theoretical energy output of each molecule given 100% efficiency? What is the formula to calculate this? My email is wooten4615bellsouthnet.

please,please help...at work i have to use a sand blasting machine and i think there are carpet tiles on the floor. i am constantly getting shocks from the machine that have me almost in tears.i have to place my hands into rubber gloves built into the machine. I have tried 'earthing' myself with a piece of copper wire attached to my leg and onto the floor but no difference.I have also tried spraying the floor with water. if any one can give me any advice i would be very grateful. dawn

Your site is a great source of information - I run science clubs here in Delhi and was looking for an interesting activity to be done related to Static Current. I am thinking about getting the kids to make a static charge detector - something on the lines of electrometer array. Instead of the whole big array, I was wondering if we can make that on a PCB and the children can take home and play with it. Let me know! Thanks, Tarun tarun dot bhalla at gmail dot com.

Hey, i was reading about your IR goggles! I thought you might like to know of a few other sources for your lenses! 35MM cameras have adapters for IR filtering (and blocking, it's quite cool!), but those attachments to existing lenses can be expensive (but the optics are strictly IR only!) another way to do it is to buy a roll of film, or photographic paper and don't expose it to any light. instead develop it right away. you'll get a black sheet of plastic (celluloid or whatever the large photographic paper is made out of, as well) that only allows IR through. If you have a friend in college that's taking a photography course, they should be able to get you the sheets for free... but if not, you can buy a roll of 35mm film and just use that, too. Hope this helps! :-D

Excellent web site. Another electricity misconception: That R=e/i is Ohm's law. It's actually the definition of resistance. Ohm's law is that at constant temperature, low currents, and other assumed conditions, current flow is proportional to applied electromotive force in some conductors, which are in turn called "ohmic" conductors. Drives me crazy when those two things confused. dxk10@DELETEcwru edu

I am no "physicist" by any chance, but the remark "There's a lot of complacent self-deception... among physicists" made by Charles Dillingham (Clarkston, GA USA - Thursday, August 23, 2007 at 12:55:21,PDT) has caught my empathetic attention.
A remedy has to be found, though. (It's possible that critic C.D. has some remedies up his sleeve, but he hasn't spelled them out anyway.)
As for special relativity, I have tried to address the issue in some modest degree at the site mentioned above [http://www.geocities.com/srmrao1/ -- courtesy (software rights) Shara Digitals Pvt,Ltd, Bangalore-560054]. Would C.D. be inclined to approve of this little effort?
Next, as for the question on electronic spin, it was real botheration to me for many months on end, but now I hope I've at last unearthed the relevant down-to-earth answer with all the snobbish math discarded. Would C.D. be interested to hear how -- or has he already resolved the issue to his satisfaction?

This site was very informative, but I have a question about stun guns. The way I understand it they have a very high voltage which will stop you but not kill you. I am still learning but if voltage is electricall pressure and the "electricity" which flows through human bodies is charged particles that are already inside our body why is it that when you add the extreme high voltage of the stun gun it doesn't kill you? I was told it was becuase it was very low amps. If voltage pushes charge and amps=one coulomb of charge per second and the charge is charged particles that are already in the body how is amps reduced?

Hey Bill! Just a quick note to let you know I've enjoyed your site for over ten years now. In fact, your site was one of the very first websites I EVER visited when my family subscribed to an internet provider the first time in 1998. I was a high school student, and my first fascination with the internet was the possibility of finding cool science project ideas. Naturally your site came up high on the list. Anyway, while I don't browse here as often as I used to then, I still have you in my bookmarks list, and every once in a while it's fun to see what's new and cool -- like melting a beer bottle in the microwave! Thanks for all the great entertainment, education and for getting me in trouble with my mother for trying things with electricity and smoke rings "at home" way back in the 90's. -Dan

A great science fair project could be developed from this work. A simple and inexpensive apparatus can be used to measure a spin force around humans, animals, plants, bowls of fruit. This fills a gap between spin of sub atomic particles and spin of planets, stars, galaxies, and super galaxies. The amplitude of the spin force around humans has been found to vary with solar/geomagnetic activity, vitality of the subject, phase of the Moon, and sometimes, for some subjects, intention. Remote healing by 20 subjects influenced the amplitude in 17 trials. Observations by one Russian, indicated that spin forces radiate very much faster than light. It is suggested that 'spin' be assumed to be a fundamental force, replacing magnetism, which is a special case of spin. Please check my website, www.buryl.com . Click the "Spin" link. There you will find more information on my discovery.

In the case of the UFO binoculars seen on a different page that had a link to this one. Use a reflecting telescope and place the solar cell over the top of the secondary mirror. I suppose this could be done with a huge telescope and clean electronis to reduce the "hiss" noise but have not read about that being done.

How about something on less fantastical potential alternative energy sources: hydrogen producing algae or bacteria, elecricity-producing bacteria, biological fuel cells, synthetic photosynthesis and so forth... No matter what it is, all the scientific brainiac orthodoxy always seem to say it'll take 20 years regardless. Maybe several someones not so rooted such science dogmatism, and/or without too much vested interesed in jeopardizing petroleum-stock portfolios might just actually come up with something and be able to make it public knowledge, that is, before the petroleum/neocon police come knocking on their doors with an offer that s/he couldn't refuse, i.e.: "hand over the patent and the prototype... or we'll ruin you...or worse."

For example a higher speed limit will not always result in traffic moving faster; in most cases having a lower speed limits reduces bottlenecks and improves traffic flow.

i am a freak the c.d skips when i am stressed, if i am in a bad mood i blow the amplifier, if i am feeling energetic i turn my car head lights off and the light remains on, every car i used to go in - the car battery would go flat, street lights on off, if i am tired brand new batteries go flat, my laptop computer won't turn off, machines hate me as i tend to break them - i really think i am the interference disk to stop humans from being mind controlled by aliens, i think i am a genetically modified human, perhaps i have alien implants in me and these cause interferrance, i use to wake up in middle of night and go outside - always i would see at least two satellites going past - perhaps my thoughts bounce off satellite and onto another, i saw four alien ships - the control room they wrapped me in green light and when i went to bed they said were putting me in hospital and i saw a green light scanner on my ceiling - i was terribly ill at that time and they healed me - i know i not crazy - they told me to put my helmet on - (perhaps they meant my virtual reality helmet - they said i from andromeda and since i got da green light i have been able to heal people - miracles - my boyfriend had a brain tumor and i saw green light over him and he now lives, other people had made me take my hands away as they have felt electric shock and a lot of heat go through the parts on them that need to be healed - they say they can still feel the heat days later - they then become healed - i am scared that i may be found out as a freak and scientists will want to cut my brain up and do tests on me - i heard in my bedroom a voice that said i was a fine specimen - they think i am just an animal but that makes them not very highly evolved to think of me and treat me like an animal - they have also saved my life however i use to hear invisible helicoptors and had an ongoing fight with machines on a radio - the machines started to hate me and eventually disowned me as i think i did their poor heads in ha ha i say their experimenmt got out of hand and i toughened up and kicked their arss as in dreams the hypnotising grey aliens now have to wear protective glassers as i will hypnotise and over power them these days - yeah i a human - not superhuman just a super human

From where does electron flow, from higher potential to lower potential or vice versa. The lecture of college said that it was vice versa in a DC circuit. It means that current flow from higher to lower potential. But in the case of a condutor connected to an ac outlet, current flows due to the movement of electrons(i know it is the real fact about the conduction in solid metal) and the current flows from higher potential to lower then what about the direction of electron. Please help out as quick as possible. Trusting in ur answer
[ "higher" and "lower" can be misleading, since a large negative potential is "high" voltage, yet it's negative, so it's "low?" Better to say that electrons in a passive load will flow from MORE NEGATIVE to MORE POSITIVE potential. Positive ions flow the other way. Wires conduct because of their movable electrons. But most non-metal conductors (plasma, salt water) contain movable positives AND movable negatives. (Also, electrons in a generator coil or on surfaces of battery electrodes will flow backwards against any potential measured on the generator or battery terminals! "Charge pumps" such as batteries and generators push electrons backwards against potential, that's why they are sources of energy. -billb]

I first came upon the concept of 'wave theory' and 'friction' as they relate to traffic, in a book I read in the 1970's called "Expert Driving". I have also noticed the 'calming' effect that a single vehicle can have on a huge traffic stream. It won't take very many people operating in this manner to have a HUGE effect on traffic, accidents, and commute time! Resonance is a truly amizsing thing! -bob

I was reading your eletrical people story, but didn't find one like mine. I have no control over it or when it happens, but plenty of witnesses. I feel an eletrical current running through my hands sometimes when I touch them together or touch another person, usually when I am very at peace and feeling a lot of love. I can actually touch another person's face when this is happening and rub the outside of their ear and they will hear a buzzing noise like I was running something electrical over their ears. It freaks them out and me too. Ever hear of anything like it?

Hi, Bill! I've enjoyed your website for years. I found it early on in my mad (read, 'amateur') scientist haunts. I started to build a tesla coil years ago. Got as far as a really AWESOME secondary coil; it took many hours, many nights to wind it myself by hand. Then I tucked it away in a corner of the garage, out of site, out of mind. I rediscovered it last spring when cleaning. Picked it up; it was heavy at one end, so I gave it a slam, dislodging the rat's nest, turds, etc, that came plopping out on the concrete floor. So, that coil was tossed. But it got me back on track. This time I've acutally bought a nice, new, suplus flyback transformer, and a 4" sphere for the topload. I think this time I'll actually build the thing (but will buy the secondary, pre-wound, from eBay!)and maybe even have some fun and not fry myself in the process. Keep up the good work!

I could kiss you right now for FINALLY clearing the 5year "how the $&@! do transistors work?!" fog from my head. Your explanation was perfect. I hope you do someday find the time to replace the ascii drawings w/ animations but I highly commend you for the excellent "drawings". : )
I've finally found someone who understands my sensical dilemma. How very
compassionate of you to take the time to dispell the wall of confusion
facing so many people. I graduated in physics, took an electronics
course, walked away w/ ZERO electronics knowledge and still don't know a
single person who graduated w/ me that could explain transistors. It took
your site + a 35year IBM veteran to place me where I really wanted, and
should have been, my senior year of college.

The web site http://www.sailmag.com/cclasscats/ shows an example of an sail for class c catamaran that is symetrical and is a good example of your assertion that a "wing" does not need to be curved above an flat below to generate lift. I saw this up close in Bristol, RI yacht club recently (Aug 2007). Since a yacht has to tack in both directions into the wind it would have to be symetrical. Interestingly, the flap at the back is very large.

I have enjoyed (only briefly, so far) your web site. Just a quick comment: Have you ever considered that some of the more advanced concepts in physics are also ... well, simply wrong. For example, no one on Earth actually knows what electron spin is. Sure, I understand the Dirac equation and its derivation, but no on knows what electron spin "IS" in terms of bouncing balls and walls you can punch with your fist, and so on. And, another example: The universe we live in is three-dimentional. Duhh. Einstein published the SR articles in 1905, and when the mathematicians came along (I forget which ones) and described it all as four-vectors, Einstein said something like, "They've taken my theory and recast it into a form that I don't even understand!" (He was being hyperbolic, of course.) And, BTW, time is NOT the fourth dimension. The "fourth dimension" (which is merely a mathematical convenience and does not actually exist) is not "t", it is "ct" -- it's the *distance* that light would travel in vacuo in time "t". And never mind string theory. Don't take me there.
Physicists believe that if they understand the math, then that's all there
is to know and if you ask questions, you're just naive and dumb. Nobody
even knows why inertia exists! (Yea, yea, OK ... maybe it's the Higgs
Anyhow ... these are just friendly comments ... There's a lot of
complacent self-decption out there among physicists.

Mr Beaty, I have been an electronics technician for more than 30 years, have made plenty of money, am confident in my trade but have to admit, don't really know that much about electronics. After sufing the web for a better understanding of transistors, I found your sight. Thanks for being down to earth and straight forward. I look forward to developing my own gut-feeling about the trade that I "thought I knew" a lot about. I know you're busy but I would enjoy staying in contact with some of your other readers.

Weird phenomena in Seattle... On Columbia ave, walking up the hill between 2nd/3rd on the sidewalk next to the United Way building, something strange is oozing from the cracks in the pavement. It's been there for several weeks, and hasn't evaporated or washed away. It looks like water, but it's solid!
I've stepped in it to see if it was water, it's not, it's some kind of
glassy material. At first, I thought it might be spilled resin, and the
largest patch appears to be 'emerging' from a intentional seam in the
concrete, which would make sense if someone spilled some there, and it ran
downhill. But further down there is more 'weeping' from a stress crack in
the concrete, like water can do. This stuff has been there for a month or
more now, and it hasn't changed. It seems to have emerged sometime in the
past, and then set up.
I've seen small 'soda straws' and other cave-like things growing from the
undersides of old concrete bridges, but this material is water-clear! It
looks like water-glass, but I can't think of a way it would form in
I may try getting a sample later.
This theme is closed, or here it is possible to ask a question? Thanks...

Look at what you are reading because what you are reading is relative to what you are thinking. Look at what you are thinking because what you are thinking is relative to what you are feeling. Look at what you are feeling because it is relative to what time it is relative to an initial inertial frame of reference.
You need to learn to count cycles of feeling and where to start counting
from. I need to learn what you know. Stop moving and you will find the
point of reference I am talking about.
I owed you one;-)

Ref Tesla's mistake. Take a look at Konstantin Meyl's work: http://www.etzs.de/onlineshop/products_new.php and especially get to grips with his scalar waves experimentation kit, that demonstrates the interaction of the spherical antennae. Have a think too about his spiral coils (as Tesla used) and think what the electromagnetic induction properties are of constant speed waves around a coil of decreasing radius. There is still more to this than regular school physics. For example Tesla measured the Schumann frequency of the resonant cavity between ionosphere and planet surface which was later corroborated, and also the scalar frequency, which Meyl corroborates.

Mr. Beaty, I just want to say thanks for the infrared goggles project. When I came across it last year, I had been looking for ways to make ultraviolet pass goggles - obviously considerably more dangerous when looking around outside, but still fun. I happened to break one of the filters I was using a few weeks ago, and figured what the heck, let's order some Congo Blue gels as well.
I received my gels today and was thoroughly amazed by the results,
especially with regards to flowering plants. Blood red sunflowers look
pretty amazing. I plan on trying these in tandem with my UV-pass filters
eventually, so if I notice anything particularly interesting with that
combination I'll let you know.
Thanks again, and keep experimenting!

It's website is in Dutch at http://www.teylersmuseum.nl/index_flash.html I always think it's fun surfing in languages I don't know. However, they have a great *.pdf tour at the rather long address of http://www.teylersmuseum.nl/dossiers/files/Dossier%20Welcome%20to%20Teylers%20Museum.pdf
Enjoy, add to the list, and if you want to visit Amsterdam, I recomend staying in Harlaam.

Many years ago, when I was working for SLAC in Menlo Park, CA, a friend of mine came in on the midnight shift with a Toyota rear axel and two bearings. He said he needed a 40 ton press to press the bearings on the axel. I said I didn't know where they had such a thing, but I knew another way to do it. We cleaned the axel off real well and went over to the liquid nitrogen tank they kept in the research area. It was three stories high, and about 10 feet in diameter. We poured some LN2 on one end of his axel and the bearing went right on....After it warmed up, we did the other end the same way......Saved a lot of time not having to search for a 40 ton press!

Just a thought about your traffic model. I thought about the phenomena too, but it seems that you've left out one of the rules I considered key: When the cars/road ratio increases -- even for very small lengths of road -- cars tend to slow to adjust back to "safe" following distance. There's more than one idea in that, but it's similar to a "virtual" accident at the point of increased car density -- which takes on a life of its own. By the way: Neat site!

I discovered this week that my house is not grounded. When I had the original galvanized plumbing replaced with the latest and greatest Plastic pipes I lost my ground line. Before cooling my house this year I had an ominous feeling about the status of the evaporative cooler. For some reason I remembered the cut line hanging off the exterior of my historic home which now hung from the electric box into thin air. Just dangleing there. I called the plumber. He is licensed. He is a professional. Well, the company is anyway. Intially the company came to bid the job as if I was a new customer. After showing the plumbber the dangling wire his eyes got large. The Manager of the company is coming tomorrow to place an 8 foot metal rod into the ground. He says casually that I need a sticker on my electric box indicating I have a "non metalic" home. I told him I think I need more than a sticker. I am not sure what the actual danger has been living in a non grounded home.I am getting a long rod after a long difficult conversation. I am an educated woman. This may be a hinderence. I think it is serious not to ground a house. I think it is really amazing nothing has happened. I am thinking that perhaps this is a big deal. I have gone on line to look up "Grounding". Your article makes sense to me. It appears to be important to a lot of people that everything be grounded. I am confused how anything actually worked since the house is not grounded. The refrigerator is running. My phone is charging. I am using my laptop un-plugged now that I know for sure the house is non-grounded. I won't use the dishwasher, the washer machine or even my juicer. I feel fear. I feel unsafe. If they don't complete the rod installation tomorrow I am planing on sleeping elsewhere until the job is complete. Am I over reacting? Electricity seems like a big deal to me. I am flabergasted that the plumming company is so relaxed about making the install of the rod. I called three times after the plummer saw the situation to get a solution scheduled. The owners would not take my call. The poor receptionist had to listen to me go on and on each time explaining that it is 103 degrees outside and I can't turn on my cooler. My house happens to have air conditioning too, but I can't imagine using it as it is a brand new appliance installed just prior to the severance of the ground line. I don't want to fry out my new machine and burn my house down. Am I being over dramtic? Last week three houses burned down in Tucson. It caught me attention on the news. It is what actually prompted me to remember the dangling ground line.That and the 103 degrees creeping in. What do you think Bill B. I see you are swamped. I will post this note and see what others might think. Thanks for not spamming, Thanks even more for the information.

Hey Bill! I think I finally managed to release the ID monsters you talked about.
I was at a holiday, at the bathroom, about to take a
poo. But the toiler paper was inconveniently placed at the back wall, same
as the toilet. Annoying to reach for.
The obvious solution would
be to simply place a roll of toilet paper in front of me on the ground.
But in a fit of creativity I decided to ignore the obvious. I instead
figured that since toilet paper is normally placed on a wall to your side,
it might be the best place. So I turned 90 degrees left on the toilet.
But the shape of a toilet is such that it was too short now. So I
decided to turn another 90 degrees and sit on the toilet backwards, with
my legs around it. But I had my pants pulled down to my ankles, so I
couldn't. The obvious solution would be to take off my pants completely. I
ignored the obvious solution.
I instead lifted my legs ABOVE the
water reservoir sitting backwards on the toilet, ready for action! Then I
realised how riddiculous this whole thing is and fell off the toilet from
laughing too hard.
I reached the insanity phase. I wonder if
genius will follow.
what a nice site you've got. just signing the guestbook for the heck of it have a nice day.

Hi all, I can only imagine the frustration of inventers in the quest for alternative energy. As a simple housewife, with no time to experiment, only a limited knowledge of the currently available options, and even less money to try anything of significance, I am totally frustrated that no one can find a simple, affordable system that the individual homeowner can put in place, that wouldn't conflict with local zoning, or look like crap up on my roof. I'm tired of seeing projects that would ultimately still depend upon those wires on poles sending me the energy I use. (read also as - big gov't bucks to fund the power companies' efforts that in no way will lower the bills) Somebody, PLEASE - power a home for a year!! There would be no better proof in a product. If it can be done for under $5k for the equipment, you will find investors, believe me. Shoot, forget investors, just start making/selling it yourself. Isn't that how Bill Gates started? In the garage?

Hi Dear Bill B., I have a few questions for you if you don't mind answering or if you have the time to do that, here they are:
Are Wommelsdorf Generators and Van der Graaf Generator both electrostatic generators? Can they also be called Potential Generators? What about Tesla coils?
Which one is better or what are the applications where you would use one over the other one?
Are Van der Graaf Generators amplifiers by nature or can you obtain amplification by cascading them?
What's a better device, a regular Tesla Coil or a Van der Graaf Generator? A "Real" Tesla Coil ( I saw your explanation for this on the net, having a "third coil", forgot now the purpose) or Van der Graaf Generator?
If you wanted to create huge voltages (millions upon millions of volts), could you use a Van der Graaf Generator to create your initial "BIG" potential and then use a Tesla Coil or Real Tesla coil to further Magnefy your initial BIG voltage?
Thank you, and I hope my questions are of interest for you too, regards,
After I read the explanations on electricity and related topics on your website, I had for the very first time began to understand what exactly electricity is. First the first time I could perceive the subject matter of electricity so clearly. If all teachers and text books in the world were as precise and as clear as your explanations here, the world would have been a much better place. Thank you very much for your great service and please keep it up.

I am just an old layman, who likes to have gut-feeling understanding of my universe. About 2 months ago I saw a physics article without to many scary equations, so I decided to read it. It lead to my most intense study period yet experienced and with plenty of despair. Your site finally got me through. It probably sounds lame to others that what I finally realized is just that energy has no mass, not even a snip of plasma or a single electron. Those things have energy but aren't. I always tried to pin something to it, a beam, a wave... Now I get it as nothing but a principle. 3 days ago I understood it. 2 days ago I really-really got it, and yesterday I accepted it.

I tried the microwave and steel wool approach for "bigger better balls" of ball lightning and can confirm it worked four times out of four i na standard doemstic 750W oven. Power only needed for 2 seconds. Would suggest the bigger the Pyrex container around the steel wool the better to enable the discharge to last a bit longer.

I try to be courteous to drivers merging in to my lane when things get tight on the freeway. But what of the motorist who feels that he/she is too good to wait in line with the others and seeks unfair advantage by driving up in a free moving lane such as an exit only lane or even the shoulder, and then wants to merge in at the last moment? I am not so kind to these arrogant types. F.M.
[ But nobody can stop cheaters, they can force their way in. If you try to block them, your fight causes traffic to come to a halt. Also, in many situations the "cheaters" are perfectly normal people who missed seeing the end of a very long backup, and nobody is letting them in near the back of the line. It's not like a queue at a bank teller; since they cannot drive backwards to take their fair place at the back. When I'm in that situation, I see the close-packed people in the line as having an "I've got mine" attitude. If they won't let anyone in near the rear of the line, then we're justified to take our fair place: at the front. In actual practice, I like to get in line early, then let huge numbers of people get in ahead of me, still at the back of the line. This often shatters the traffic jam as I approach it, since the jam was entirely created by people who pack tightly together and prevent all merges except at the very front of the line. By letting people in early, I eliminate the supply of cars that have to butt their way in at the front. Since this technique works, it shows that those people weren't cheaters at all, since they happily take their place near the back end of the line... but only if the people back there open up some space. -billb]

I am a math/physics prof w 20 refereed publications. Over the past few years I have concluded the following:
1)My research is useless unless students are involved.
2)Students won't do research for free unless it's fun.
3)Very few students are sufficiently dedicated even if it is fun.
4)To get those who are truly interested, I have must collaborate on-line with students outside my particular school.
Hence I came up with the science of boatbuilding. For more details, as well as ideas for science fairs projects in "boatology", visit my non-comercial website at:
