So last week ThinkGeek announced they are sellinlg packs of "BuckyBalls Magnetic Building Spheres" which include 216 1/8th inch (3.17500 mm to me) spherical rare earth magnets. Noticing this is 6 cubed, I was trying to decide whether to buy 2 or 3 packs, and eventually settled on buying 6. They should arrive shortly... Dom S Wamboin, NSW Australia - Sunday, May 17, 2009 at 04:36:21 (PDT) Have you, Bill, or your readers, seen schematics for an electronic device use to copy homeopathic remedies, "potentize" them, or make them from raw substances? And/or how does one select the potency with such a device? I've seen one used, but I don't know what was inside. It looked like a coffee mug warmer, a little platform onto which was placed: (1) a glass vial to receive the imprint; (2) substance to be copied (either another glass vial bearing an energy pattern, or a raw substance). I'd like to try making one myself. Seems closest to Benveniste's digibio and may try Rick Anderson's circuit, with white noise, or just EMF pulses as sharp as I can make them. L. Gray Kansas City, KS USA - Thursday, May 14, 2009 at 03:35:31 (PDT) We've developed a science education TV and web series called, "I Can Be..." which focuses on career information with an emphasis on the sciences for middle school aged children. This is a labor of love I self financed because I think people working in the science fields who love their work are better role models for kids than hollywood celebrities. The website" www.i-can-be.com offers free information and content from such notable places as Scripps Institution of Oceanography, the Condor Recovery Program, the Los Angeles Zoo and the newest school of veterinary medicine in the country. You can check it out at: www.i-can-be.com Free video content and information about animals featured in the zoo segment is included on the site. Our site also offers a DVD for sale by schools and the DVD is also being distributed by the Library Video Company. Dan fullerton, CA USA - Friday, May 08, 2009 at 15:47:35 (PDT) In response to your beautiful insight on "How are Watts, Ohms, Amps, and Volts related ?" I have a question. I am an amateur but heavily enthused and pushing full speed ahead into the realms of electricity. My curiosity is this, As more current flows through a wire, and this causes ( I assume ) some proportional increase in heat, Does this also cause the field around the wire (of 'electrical energy' , watts or joules per second if I am correct) to proportionally grow larger or smaller in diameter in relation to in increase or decrease in amperage ( or resistance ) - aka heat ? And to clarify technicality, is it safe to say that the 'electrical energy' around the wire forms the shape of a torus whose inner most layer ('the doughnut hole') is 'perfectly' butted up against the outtermost layer or 'skin' of the raw wire itself ( taken for granted the physical presence of the insulation around a wire in this case is completely neglected by the 'electrical energy' or field of joules, as if it - the insulation - does not even exist ) ? I hope these make sense.. I'm growing terribly fascinated and would appreciate any depth of response. Thanks, Mark Mark Grote louisville, KY USA - Wednesday, May 06, 2009 at 23:20:13 (PDT) Interesting. But, so what? Even if scientists sneer at what they disagree with, the burden of proof rests with the claimants. Even if conventional science makes 1000 mistakes, the burden of proof remains on the claimants! ed thomas USA - Wednesday, May 06, 2009 at 06:24:59 (PDT) The code of the pyramid like starry gates can open the way to the stars, but it can be a weapon of self-destruction for our civilization as well. The history of science shows, that many scientific discoveries didn’t only serve for mankind, but were against people and civilizations. http://www.amazon.com/Pyramids-Architect-Universe-Petros-Petrosyan/dp/1595268537/ref=sr_1_1?ie=UTF8&s=books&qid=1238548371&sr=1-1 Petros Petrosyan Chicago, IL USA - Saturday, April 25, 2009 at 13:56:27 (PDT) Bill, hi. Very good articles, trying to put all the dots about the 'i's. However, you don't explore the fact that we don't understand what an "electric charge" or "electric energy" actually is! Fundamentally, we have no idea. You do give a sort of a definition to charge by saying it's "sybstance-like", but that's not really an explanation. On a basic level, we talk, use and produce "electricity", but really have no idea what it is...

I can't find anything! It would be great to show illustrations of "angles of escape" (during normal driving conditions) showing how the closer you drive to the person in front of you relative to the speed at which you're traveling, the more trapped you become, the less your field of view you have around the car ahead of you, and the more stress you heap upon yourself as a result of having to be wound up enough to always react that much faster than those who keep a good distance back (and can relax that much more as a result). Here's a good analogy: Picture playing tennis the normal way, then try playing it on the same court, half the distance from the net. That would prove challenging and even frustrating, yet tailgating while driving is a lot like that, and people don't seem to realize it. Pretty please, with sugar on top: Create some illustrative diagrams?? I don't have that talent for programming applets or drawing illustrations on the computer that you do, or I would have done this myself and shared it all over the internet. Malee Holland Orlando, FL USA - Friday, April 17, 2009 at 13:33:52 (PDT) Has anyone else toyed with the idea of an electric gun? Basicly a solenoid for a breach. A crude setup is a 35# coil wound around a none conductive breach and using any smoothbore pipe as a barrel. The charge to the solenoid is basicly a car ignition system. The ammo is simply a bit of iron bar to fit the bore and you eliminate the dangers of storing and manufacturing cordite ect. Thought i'd offer the idea to you guys in the USA to tinker with as you have so much more freedom to play. Us brits play with guns responsibly and we are instantly labelled terrorists by the socialists in charge. Somebody get me a green card & a lab, maybe our heroes could have reliable kit. Sorry, last bit was my rant against comrade brown.

As the load increases on the traction motors, more power/electricity is needed from the generator/alternator, in turn making the diesel engine working harder and harder. Why? Is there some resistance building up inside the generator as demand for electricity increases? Please help. richard van emrik Corning, NY USA - Monday, March 30, 2009 at 17:56:24 (PDT) I have just uploaded two better drawings of a WHALE'S TAIL windpower generator design, explaining the BERNOULLI PRINCIPLE advantage (thanks to Bill's work), and also incorporates Tom Kasmer's HYDRISTOR.

I learned some tricks I've not seen before, and I've been trawling for info on my Wimshurst for ages... I love the pop bottle motor, I'm going to try that! But regarding a power supply for it, you mention that a Tesla Coil may or may not work. Well it depends on the coil - typical coils are air-cored and charge-pumped by a fast DC pulse, not AC, so it makes sense that any ungrounded capacitative surface will get a bias over a grounded one in the field of a working coil, as the field is biased. Bearing in mind that a sizeable coil can put out kilovolts of AC / Pulsed DC, its going to induct a fair bit of that into the plates. If the coil is charged by an AC wave instead of a DC pulse, then there will be no overall bias and the ungrounded plate will not charge, and the motor wont run. Tesla was experimenting with tuned coils to transmit power through the air to boats hundreds of meters away, before his death; there still exists a tower intended to house the transmitter on the US coast somewhere. I should look up where ;) Jez HexHammer UK - Wednesday, February 18, 2009 at 14:25:35 (PST) G'day, Just wanted to thank you for an awseome site.

We made one with two magnets that I ripped from a microwave someone left by a dumpster. After an initial design with some problems, I used your debugging and placed the magnets in cylindrical sea salt container and used the solenoid you recommended (actually pried it apart with a regular pliars and screwdriver). Anyway, worked like a charm. One little twist lights the recommended bulb just fine. Keep up the good work.

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.

Bailong USA - Friday, December 26, 2008 at 10:35:40 (PST) 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! Paul Hoegstrom Oklahoma City, OK USA - Wednesday, December 24, 2008 at 11:29:08 (PST) 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. Mark L.

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.

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 Robert Turner Sydney, NSW Australia - Wednesday, November 26, 2008 at 16:08:30 (PST) THE ELECTROBULB!!! you will need: 1 metal wheel 1 set of petals 1 seat 1 ajustible bar 4 plexi glass sides 1 metal plate 1 lightbulb and socket 2 metal rods 1 set of electricity wires haley abernahy USA - Wednesday, November 26, 2008 at 04:13:47 (PST) Bill, Great site.

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!

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? Ari USA - Tuesday, October 07, 2008 at 19:38:28 (PDT) Very useful resource, thnx!

This could be achieved by switching between driving the motor/generator and charging the battery at separate times Dale USA - Friday, September 12, 2008 at 20:45:18 (PDT) 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!

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.

Darwin Belk Davenport, Ia USA - Wednesday, August 20, 2008 at 16:51:09 (PDT) 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.

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.

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.

F Napolitano Chicago, IL USA - Thursday, July 24, 2008 at 00:33:04 (PDT) 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 Don Masturzo Fallbrook, CA USA - Wednesday, July 23, 2008 at 16:46:02 (PDT) 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'?

Kyle W Philadelphia, PA USA - Tuesday, June 24, 2008 at 15:17:07 (PDT) 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. Marizza Bailey Hot Springs, AR USA - Tuesday, June 24, 2008 at 07:09:34 (PDT) I found your site looking for info on electricity, Wow! It is truly a rare pleasure to find someone with a real appreciation for the fundamentality of ideas and a love of simplicity. Most "experts" these days tend to be drawn towards complexity like mosquitos to bugzappers. It's a rare breed that can recognize that simplicity in the face of the complex is where all the fun's at. Thanks for all the info! Michael USA - Wednesday, June 18, 2008 at 16:30:32 (PDT) Just came across your website for the first time and thoroughly enjoyed the insite! one question though, when talking about charging just one plate of the capacitor and leaving the other plate unconnected, I follow the reasoning but can't figure out how it could be done in actuality! This is one of the things that really slows my comprehension of physics and sadly, always has. Is this theory ONLY? Thanks, Grant Grant Houston, Tx. USA - Wednesday, June 18, 2008 at 08:00:58 (PDT) 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. Thanks you, for giving me your costly time From: - Balram Tiwari Plot No. 48, Bank Colony, Yamuna Nagar, Haryana, India. Pin Code-135001.

I've never quite understood electricity – for exactly the reason you articulate, it is used in a fundamentally incoherent way – and for the first time, all kinds of things make sense. Thanks!! -- Ben. Ben F New Haven, CT USA - Saturday, June 07, 2008 at 17:47:38 (PDT) 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!

M. Fontenot Houston, TX USA - Sunday, June 01, 2008 at 15:29:12 (PDT) 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.

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.

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. H.

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. Michael 'SasQ' Studencki Zywiec, Poland - Tuesday, April 08, 2008 at 19:16:42 (PDT) 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. ssword USA - Sunday, April 06, 2008 at 19:45:20 (PDT) Nice one!

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?

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.
