I periodically enjoy visiting your site. I ran across a footnote in an old book from the 1950's that might interest you. It's intriguing but rather vague on the specifics which would be interesting to discover and replicate for fun and/or profit:
Associated Press: "The eminent French chemist, M. Georges Claude, [a.k.a.
the father of the neon] performed "miracles" at Fontainebleau in 1928
through his demonstrations of oxygen transformations. The Associated Press
reported that M. Claude, at a scientific gathering, 'turned a handful of
sand into precious stones, iron into a state resembling melted chocolate,
and, after depriving flowers of their tints, turned them to the
consistency of glass.'"
Hi Bill (and everyone),
Wow - that's a lot of great links on your site. I wanted to let everyone know about my free Tesla coil design program at my new website www.teslamapcom
Please feel free to
check my site, and if you deem it worthy, maybe you could do me the favor
of adding a link from your website.
Your hydraulic capacitor analogy is very well done. Would it be possible to extend it? For instance, electrical capacitance can't be analogous to just the volume of your sphere, since the flexible divider could be anywhere from balloon-thin to immovably thick and stiff. But capacitance can't be analogous to just divider stiffness, because a larger divider would always allow more hydraulic capacity. Can't be just divider area, either, at least after the divider gets pressed against the far wall... Maybe the hydraulic analogy just can't be taken that far?
What I'm looking for is an analog to the perceived "stiffness" of an audio amp power supply - a concept that approaches superstition in the electrical realm. Personally I've given up on capacitors for that purpose - there is no capacitor remotely as "stiff" as a bank of car batteries!

I am an Instrumentation engineer from India. Its been 2 years I passed out of college, but could never understand how a transistor worked. Basic queries never got solved and I never wanted to just summarise the mathematical equations to satisfy myself. I was too scared of Electronics, since everything was built from transistor, about which i had no clue. No good books, be it Millman, could sove my queries. Your article today has created an interest in learning electronics and getting a hang of this subject. I have recommended this site to everyone. Thanks a lot.

I know you said no advertising, but this is a non-commercial (educational) site, and I do think you would find it interesting ... however if you absolutely will not tolerate any advertising of other sites then just ignore this message. :P
The website is www.larryspringcom and it details the findings of Larry Spring in areas such as physics, electromagnetism and quantum mechanics. The site also features Flash visualizations of Larry's discoveries such as magnespheres and the Spring atom.
I find the visualizations and information presented to be very educational, and it is all 100% free, without advertising, no membership required, etc. etc.

The section of your website on electricity and especially transistors and capacitors is excellent. I always had a hard time understanding how transistors work and your explaination is the best I seen anywhere. Please post an explanation on how diodes work as well. I'm the kind of guy who likes to know how everthing works down to the subatomic level. :)
Also holes are just spaces where electrons used to be or are they empty spaces in the electron cloud of the atom or both? ['Holes' are actally semiconductor atoms which have one less electron than proton, so they're positively charged. But a neighboring atom can donate one if its outer electrons to the "hole" atom. The hole vanishes, but now the neighbor becomes positively charged, because one of its protons now lacs an electron. "Holes" are like wandering protons. But in fact, the positively charged proton is only "revealed" when one of that atoms' electrons is missing. As the hole moves around, it reveals an un-cancelled proton in the semiconductor atom where the hole is located. -billb]

To whom it may concern:
The so-called transformation of carbon into steel, carbon into oxygen, sodium into potassium and even the dubious tranmutation of mercury into gold all seem to either require, or at the very least, all have the presence of oxygen in common.
I found the following references in the footnotes of a book from a book published in the 50's. Curiously in subsequent editions, these two references are conspicuously absent:
1--Associated Press, 1928, Fontainebleau, France:
"The eminent French chemist, M. Georges Claude, performed miracles at Fontainebleau in 1928 through his demonstrations of oxygen transformations. The Associated Press reported that M. Claude, at a scientific gathering, "turned a handful of sand into precious stones, iron into a state resembling melted chocolate, and, after depriving flowers of their tints, turned them to the consistency of glass."
There is practically nothing on the web about this man, except for his work with neon and fluorescent lighting. "Oxygen Transformation" with his name yields nothing insofar as I am able to research. A little digging at the local library repeated the above; and that he was unfairly accused of being a collaborator, imprisoned, but then released due to his wealth of friends who lobbied upon his behalf. He also had some theories about harnessing sea water temperature differentials.
2--Charles Kellogg, the California naturalist (source unclear), gave a demonstration of the effect of tonal vibration on fire in 1926 before a group of New York firemen. "Passing a bow, like an enlarged violin bow, swiftly across an aluminum tuning fork, he produced a screech like intense radio static. Instantly the yellow gas flame, two feet high, leaping inside a hollow glass tube, subsided to a height of six inches and became a a sputtering blue flare. Another attempt with the bow, and another screech of vibration extinguished it."
Even Encarta acknowledges the illusary dual nature of matter; that it is actually all energy. Thus even matter has both frequency and amplitude like all forms of energy. If one could ascertain and reproduce those two with something that could approximate it, what effect would that have on matter? Could one store and reproduce such frequencies similarly to how one would with sound, radio or light waves? Would it be a coil/capicitor arrangment perhaps so fine that it would have to be designed with nanotechnology, or are there crystals out there, that could resonate to the appropriate frequences if properly stimulated?
If you can find the particulars for the replication of those two aforementioned citations, I would be particularly interested.

Hello, I read your explanation of how current moves quite slowly, of the order of cm per second. How is it that information such as phone conversations can travel in wires at much higher speeds ? Is it that the waves of energy travel fast, but the medium (analagous with water waves) travels slowly ?[Exactly. If you pull on a chain, the links move slowly, but the *wave* moves down the chain very fast. -billb] Thanks. Jan

Hello Bill! I stumbled upon your page while reading about plasma globes, and have spent an evening reading many of the pages. I was particularly intrigued by your "electric humans" page. I've always been particularly sensitive to electricity, shocking myself easily and being bothered by a TV on several floors below.
Recently I had an usual experience that you might be interested in hearing about. I work as a Geologist for an environental company, and running over our large parking lot is a set of high-tension wires. We recently had two weeks of steady rain, and on the aftenoon the rain was finally letting up I was leaving work. As I walked through the parking lot I could hear the high-tension lines making their typical "sizzling" noise they make during rainstorms. I suddenly felt a pulling, prickling pain in the side of my face. I touched my face, feeling nothing there, and assumed there was a sharp edge on my umbrella that was scraping me. Soon afterwards I felt it again, and when I leant forward to fish my keys out of my bag I felt a sharp prickling pain in the top of my head. I jerked my hand away from the handle of the umbrella and dropped it on the ground. I realized that the umbrella was picking up a strong charge from the air, and I was getting really zapped.
It is possible that the high humidity combined with the cheap metal of the umbrella contributed to this event? My boyfriend mentions to me that he's heard that you can light a flourecent bulb by standing under high-tension lines, and now I am curious as to whether you have heard of any other instances of metal objects become charged while under high-tension lines (if that is actually what really happened to my umbrella.)
Thanks so much, and keep up the good work on the site!

http://amasci.com/traf/ I came to some of the same conclusions (though without trying to figure out why!), simply because my car gets MUCH better gas mileage when I drive a steady pace. Also, less wear & tear on the car, and reduced mental stress on me.
Ever since I was kid (in the early 70's), I have been riding a track bicycle (long before the bike messengers made it cool); with only 1 gear, no coasting, and most importantly -- no brake -- I became quite obvious that maintaining a steady pace was most efficient.

I just wanted to thank you on your comments regarding FPD, Flaming Personality Disorder. I stumbled accross this web sight, while doing a search for pathological lying. The information was excellent, very informative, and gave me the tools deal.
My ex-boyfriend has FPD. I broke up with him this past Monday. I broke the promise to myself to not get into any heated discussion, and to just break it off.
In the beginning, I did just that, and just said, "this relationship is just too intense" but as he calmy made accusations as to why, (its another man, isn't it, blah blah) I told him the truth.
"No, its not another man, its your lying" He started to breath really really hard, and he said he had to go, and hung up. Typical. Also typical, is that he denies reacting this way.
I call him back, left a message, explaining, "case in point, here we go, this is what you do. And regarding the lying, you dont have to defend yourself. I beleive that you beleive you words.
With this, he calls back. I guess he got ready for his telling his side. And here is how you deal with a Flamer. You just dont respond.
He called me back with all sorts of projections, of my lying, when I did this and when I did that, blah blah blah, but I just ignored it and said.
I beleive you. I believe that you beleive everything you say. And since you are unaware of your own contradictions, and you are not even conscious of your own actions, well then, there is nothing left to talk about. We are at an impasse. Which is good, again, he got distracted, and rushed off the phone, saying he had a client. He didn't.
I now, block all his emails, and reprogrammed my phones, for when his calls come in, or a blocked call, it gets routed to the fax machine.
So that is how you shut down a flamer. let them disappear, when they run out of arguments. Thats a good sign, that means you've won. And then ignore them at all costs going forward.
Our history is this. He usually admits I am right, after some time has passed. Then, the same type of behavior will erupt over something else. But this time, when he comes around, I will not be here. I am glad I saw the argument through to the end, and did not let him tell me, his fabricated reasons for the break up. If I let that happen, then, in his mind, he still has an in.
[Hi Tania! Rather than Pathological Lying, this sounds more like the mental stuff called "Borderline Personality Disorder" or BPD. Did you also feel like you were going crazy, or that YOU were the crazy one? BPD people subtly devalue and marginalize any honest information and insights in order to conceal their problem, and to impose their world view on loved ones. Marriage councillors call this the "crazy making" technique, also "gaslighting." Some BPD people may constantly lie and distort, but also they seem totally unaware that they're doing this. For more info on BPD, see other BPD symptoms. There are also many online support groups for spouses of BPD people, and stories from their loved ones. Good books are Stop Walking on Eggshells and I Hate You, Don't Leave Me. -billb] USA - Friday, September 30, 2005 at 06:13:46 (PDT)

I wrote to AMASCI several months ago and tonite haven't seen my comments. Perhaps my experiment is TOO dangerous to tell others? I'm an older person who ain't crazy for rap music, but notice not me, but others who get a migraine headache from the very low THUD sound those automobile "BOOMERS" make. Now, i'm a sound engineer & i been doing some personal experimentation with that low thud sound with some speakers moving golf balls and objects. I rig the wires to a makeshift radar antenna and directed the soundwaves to the leaves on a tree and the leaves fell to the ground. I tryed it on a bird and the bird fell to the ground DEAD. I aimed it at a stray cat and the cat took off like lightning. Cat never came back. I tryed amplifying it but not too much for fear of burning the transitors and the finals in the circuit board and pointed it at a grocery bag. The bag started to move a few inches and went up in FLAMES. Freak the bejesus out of me. What in Gods name did i create here??? Please post this comment for others to read. I think i stumbled onto something but don't know exactly what i created.

Sir,I visited ur site a few days ago and I must say its very different from other information sites.You really make concepts easier to understand.I really appreciate ur gesture. I had a silly question to ask.
I never really understood the motion of electrons in an ac
wave.now in a dc wave(well not wave exactly) charges flow in one
direction,but what happens in ac wave? moreover a capacitor provides very
high resistance to dc,but acts like a short in case of ac.
why direction of current in any circuit is always towards ground.(the
ground is generally the negative terminal of the battery ,but if there are
more than one power supplies,than the most negative one is considered as
I would really appreciate if u could clarify these

I have just finished reading the above page and found it fascinating as well as destroying some of the warnings of doom that abound, in particular the superheating of water.
I had noticed that the superheating rarely occurred when I was using older mugs, eg with a few worn spots to heat my instant coffee. I have found that by tapping lightly on the base of the mug with the spoon will bit by bit "exhaust" the superheating effect. Also, none of the warnings say how fierce this effect can be - I would lose over half the contents of the mug if I ws not careful. It was only chance I was not holding it at the time.
This may not be th appropriate place for my next question which is a "Why is this so" type.
About 25 years ago, in a large department store which had a very large display of microwaves for sale, I noticed that all the doors were hinged on the left side (as you face it) with the control panel down the right hand side. Out of curiosity, I have been looking ever since for a door opening the other way. So far, I have seen ONE(1) with a lift up door and even that had the controls on the right hand side.
Is this a limitation or restriction cause by the construction and/or operation of the micro-wave generator?
I have put this question to several science type forums but had not yet had a serious reply. I realise it is not very important but I am a curious sod and keep hoping

Sir or Madam,
I would like to draw your attention to a recently published web page,
http://www.geocitiescom/joeiii63 which shows that varying
the inertial mass (read as the apparent mass) in a closed system will
produce the exact same result that would occur if the strength of the
gravitational field affecting it was alternated between weak and strong.

I saw your "bogglers" explanation of why ariplane wings generate lift in Discover magazine, and hope you never design an airplane to carry you. Your explanation of lift goes against 100 years of flight experience and airfoil design. [ LOL. Should we trust you, or should we trust NASA who agrees with me, and an increasing number of aerodynamicists who see the light. See the several news articles about the controversy at Airfoil Misconception: links Also check out links to Drs. Anderson and Eberhardt's page, J. Denker's page SEE HOW IT FLYS, Jeff Raskin's page on Coanda effect, and Dr. Klaus Weltner's papers that lit the fire. -billb] An airfoil flies upside down by flying at a greatly increased angle of attack, thereby making the air on top follow an even longer path than the air going underneath the wing. [Ah, you believe in the "longer path fallacy," an error which is specifically debunked at NASA's flight education page. Wings fly because the air moving over the top is faster, NOT because the air moving over the top takes a longer path. Is this confusing? Yes, but only if you've bought into the incorrect explanations found in most grade-school textbooks and pilot training manuals. Wrong explanations are like a disease. The size of this infestation is stunning. Be careful: science is not determined by voting, and if one small voice points out "and yet it moves," that voice can defeat the combined voices of thousands of known authorities if those authorities are wrong. -billb] The downward deflection of air only provides lift within a few feet of the ground, hence it's aviation name of "ground effect". [You've got it backwards. A wing in ground effect DOESN'T deflect air downwards, instead the upwash and downwash are equal, and only tiny wake effects are produced. Most textbooks wrongly describe a two-dimensional airfoil in a 2D wind tunnel where the wing is always in ground effect no matter the altitude. Only during higher flight of three-dimensional wings does the wing begin to produce a significant vortex wake which entrains descending air, where the upwash before the wing is small compared to the downwash behind. In ground-effect the wing interacts directly with the Earth, behaving somewhat as a half-venturi. In high level flight the wing doesn't interact with the earth, but instead interacts with the air. It deflects huge masses of air downwards. -billb] The vast majority of lift is caused by the air going over the top of wing creating a vacumn on the top. [ True. That effect is part of both the Bernoulli and the Newton explanations. Those explanations are correct, it's the "longer path explanation" which is wrong. -billb] If you don't believe this come fly with me and watch the upper skin deflect upward between it's fasteners to the ribs on the top of the wing in flight. You might want to do a little more "research in airfoils and flight before answering such questions.

Hi, Very interesting discussion on your website. I see from the pictures that the air does not meet back at the trailing edge of an airfoil. The upper curved part of the air, in fact, obtains greater speed and "beats" the underneath air. So, I am confused how this "disproves Bernoulli." [ Who says that this disproves Bernoulli? Seriously. Where on my website do I say that Bernoulli is wrong or needs "disproving?" Have you been reading some other website? As I clearly state on the grade-school misconception page, the Newton explanation and the Bernoulli explanation are equivalent. They are two ways to describe a complicated phenomenon. You need to say which article you're talking about. Perhaps you're reading articles on some other website rather than mine? -billb] He says faster air has less pressure, right? And the curved, upper air isss faster...

I am a practising psychic and have often had "issues" with electrical equipment, esp. recording equipment and computers. Have you ever heard of any correlation between high electrolytes and psychic ability.?? I understand that you need to replenish electrolytes after psychic work which I have never done (probably never needed to).

Just one thing, the bit about leaving coins at a level where children can find is a cute idea. But aren't coins a real choking hazord for little kids?
[ GOOD POINT! The coins are only worth something to kids above a certain age: kids who know what coins are, and who won't stick them in their mouths. Obviously we should only put them in non-babyproof areas where other swallow-able objects are already present, and where bored 6yr olds would explore. Never leave coins in a babyproofed home, or where lots of toddlers are around. -billb]

stuff.html is freaking brilliant. Or perhaps feeping brilliant, but that's beside the point- my engineering knowledge is essentially limited to such a point that I am unable to follow the crackpot theories.
On the other hand, if you haven't already, I might reccomend picking up "Science and Health" by Mary Baker Eddy. It's the fundamental text for Christian Science, and it's nuts and wrong- but true nonetheless. Like many religions, it presents good material and then proceeds to draw exactly the opposite conclusion introspective sanity or healthy madness might suggest. It's also probably safe to skip the first few chapters. Few deliberately left undefined.
Ever checked out the Principia ( http://principiadiscordia.com/ ), the Jargon File ( ) or Organelle ( http://www.catb.org/~esr/jargon/ http://www.organelle.org/ )? I offer these deliberately without commentary, as they are all things which are simultaneously full of crap and beauty.

The only thing that's disproved is the "wing shape explanation." But this was disproved long ago. Aerodynamics experts have been complaining about the grade-school wing-shape misconception for many decades. Lifting force is created by circulation; by the air deflected by the trailing edge. Go see the NASA GRC website for a thorough debunking of "wing shape explanation." Unfortunately the misconception was taught to many pilots, and now those pilots would rather die than admit to not understanding their own aircraft. -billb] He says faster air has less pressure, right?

I've heard that triangular antigravity flyers don't work in a vacuum. A doctor of physics put a 'flyer' in a vacuum chamber which was at normal atmospheric pressure and the flyer worked but when the air pressure was reduced to that of the same level as 100km above the earth the flyer didn't work. The physicist said therefore they must be generating a ion wind. Have you heard of such research? What do you think about it? [ Yes, I've been saying this all along. Lifters are an obvious ripoff of deSeversky's Ionocraft from 1964, and they're only weird if you have no knowledge of that old device. See the first link on my antigrav webpage! See my comments on Naudin's 2001 Lifters page. They obviously produce a huge amount of ion-wind thrust. But do they also create antigrav effects? Well, only if they can produce thrust under high-vacuum conditions, only then are they interesting. Now we have evidence that they can't. Therefore, they're just ion wind devices. -billb]

Is there a commercially-produced part I can buy instead, or does anyone have any extra ones lying around that they'd be willing to barter/sell me? Thanks! [Heh. Tesla coils are dangerous... and the way to promote safety is to prevent kids from building them. Most kids don't have the patience to wind the main coil. This is a psychological safety feature! Kids who do wind it are probably obsessive nerds like me, and they're too smart to electrocute themselves. -billb]

I to drive like this,so as to not have to accelerate and brake constantly.I find it much more relaxing to leave a distance from the car infront and just drive at a nice even pace,which also saves petrol and i arrive no later than the people who have been stopping and starting for the last 30 miles.But my comment is that even if you drive like this i have noticed that the cars behind me will not keep this constant speed and will just accelerate up behind me and then brake thus starting the whole traffic jam again.The only diiference being that it's a few hundred metres behind the one in front. [Why would the cars behind you do that? They'd have to intentionally drive slow, opening up a huge space, then speed way up again to consume that space. Drivers don't do this, since they're terrifed that other drivers will zoom into any space ahead of them. Therefore they tailgate. But we use this to fix traffic, because whenever you drive at a constant speed, everyone behind you tailgates you, and they end up going at a constant speed too. -billb]

I am looking for a safe electronic electrostatic generator. I have found the negative ion generators on your page (electronic's goldmine, etc) but need something that is both safe and battery operated.
What would be a good way to limit the current to safe levels on the 12V
battery operated Ion
generator from Electronic's Goldmine? Or, is there
another option? ['Safe' current is ~1mA, so to limit
negative ion generator's nasty pulses to one milliamp, you need to install
in series with the
HV output, with the value being 10,000/.001= 10 megohms. But standard
1/4watt resistors are only good for a kilovolt or two. So rather than one
ten-meg resistor, use five 2.2meg resistors in series. And heavily
insulate the solder joints! I'd use RTV silicone (the vinegar-smelling
kind of caulk.) First cover the resistor-chain with a piece of
aquarium air-hose slit down the side, then inject the goo through the slit
to cover the solder joints. -billb]

http://amasci.com/miscon/energ1.html says electricity flows inside wires. I have heard that electricity actually flows on the surface of the wires. (I'm no authority, but I work for BellSouth and another technician told me this. It has also been my observation that ranks of BellSouth technicians are full of geniuses and near-geniuses.) [Electric current is not on the surface. That's a myth, but it's a widespread myth , and even some experts believe it. If they thought for a moment, they'd realize that if the current was only on the surface, then all that expensive copper would be unnecessary, and we could replace all the power cables with cheap plastic ropes with a microscopically thin copper film on their surfaces. In fact, electric current for DC and for 50/60Hz AC is all through the whole crossection of the cable. -billb]

William, thank you for your article HOW DO TRANSISTORS WORK? It did help me enormously to get now at least a feeling of what I have been trying to understand for years! (and I am glad to know more people feel confused about it ;-) And I have always suspected there is something wrong with saying transistors are amplifiers...

Does anyone know of a physicist or retired physicist that would be interested in writing a white paper on coulomb force law relative to cold cathode emission? Or maybe someone knows a group that specializes in this activity. The paper will be used for the writing of a patent application. The pay is negotiable. Thanks for any help, Larry.

Hi, my name is Danielle. I have ONE query...what is a free-nrg blaster? I really need to know how one can be built to help my mom with her chronic back pains. she has a friend who has one of these machines. It has electric currents that when put around your wrists send strong current/zapping pulse like currents through your body giving u pins/needles like feeling, and dramatically helps my mom's back pain. Its from Rife Blaster or Royal Life. PLEASE HELP. Send any answers to my email at danii_bujo at yahoocom.au. Thank you. [That doesn't sound like a "Royal Rife" device, instead it sounds like a TENS machine. -billb]

I ran into your page on smoke rings after a discussion with my friends. Nice page, but I think it's misleading when you say, "NO AIR IS MOVING on average." Yes, on average, but that's also true when I walk across the room -- the air I displace in front of me fills the void I leave behind me.
My friends and I were talking about those "air cannons" which
we concluded were the same phenomenon as smoke rings, but one of the
points of contention was whether they actually sent a jet of air, or
whether they simply sent an impulse transmitted through the air. As your
page makes clear, there is in fact a mass of air traveling through the
surrounding air -- which there would have to be, since the smoke itself is
What I really want to know is how the ring maintains
its shape and doesn't simply dissipate. I think that would be a valuable
bit of information to add to the page.
i get shocked alot mainly when i make beds,sometimes when i put a key in the door i can see the electicity a little blue light. sometimes when i bump into things i get the shock of my life and it really hurts how can i stop htis or at lease calm it down?

I just wanted to comment on the point that was made about truckers and their driving habits through traffic jams. I admit I am an aggressive driver and have always noticed that truckers had an unusual large space of open road ahead of them......I always believed it was harder for them to brake...I wonder if they become upset when I pull in front of them or if they have the same point of view as you in trying to ease traffic. I don't think I would attempt your driving suggestion, because in the end I would still be ahead of you! [Let's see if I have this right. You can get ahead of me by probably twenty cars during a half-hour morning commute, arriving thirty seconds earlier. But me, I know how to singlehandedly shatter huge traffic jams, or at the very least, how to wipe out miles of stop-and-go traffic. If you can use your skills to cut your commute time in half, then I'd sit up and take notice. But aggressive drivers cannot do this, instead they reduce their commute time by 1% or so, while triggering traffic jams all throughout the system. They can't go faster, so instead they pretend that they're in a race, a race where nobody else matters and teamwork is ridiculed; a race where a tiny gain will put them over a finish line. But they do this through frustration and through ignorance, and so it's perfectly forgivable. But you, you're smart, and you've read my article, so you're not doing it through ignorance anymore, eh? -billb]
There is a similar situation on my freeway route (merging lanes) to work that causes a jam every morning. The highway is a constant 4 lanes, but when we get near downtown, only 2 shift northbound to the city. The right 2 lanes going to downtown back up and completely stop for quite a distance. The left 2 lanes are slow but they still flow at a decent pace. I know some think I may be a jerk, but why would I sit in stopped traffic when I can pull all the way up to the split and merge over at the last second. If I can not just pull over, I will just slow down (even stop) and wait for my moment...hehe...causing my own traffic jam in the 3rd lane; however, people behind me are usually doing the same thing. Oh...by the way ...I am moving to Seattle this summer 2005, so look out! [Lol! About half the commuters here are EXACTLY like you. Adding one more aggressive driver to the tens of thosands on the road; that's like adding one more bacteria to the culture in the petri dish. If you want to be different than everyone else, don't try to be a "winner" like all the other bacteria. Instead, just be different. Note that only very few drivers have the courage to try the traffic-busting techniques, or the brainpower to discover new "switch points" which allow individuals to remove traffic jams. On the other hand, aggressive driving takes no courage at all and certainly no brainpower, it just takes a bit of hatred of ones fellows and a serious lack of caring of the troubles caused by one's behavior. On the other hand, Seattle police aggressively ticket people like you. They even set up 'stings' and pull over all of em, while onlookers cheer. Moving violations are very expensive tickets. If you're coming to Seattle... maybe it is you who should look out. -billb]

Hi Bill, I stumbled upon your web site while looking for kid-friendly info about kinetic energy. How wonderful it is to know that there are people like you out there in cyberspace who are concerned enough to get accurate science information out to all. As a teacher I am always trying to pass on the most accurate and up to date info I can get. Unfortunately we don't always have access to stuff that is right, so thanks a lot. Don't worry about putting it into lesson format, any teacher worth their salt can do that. JUST KEEP GIVING US THE FACTS... PLEASE!!!!

Loved the traffic experiments, excellent. The real question is... Does doing the gregarious act of attempting to remove traffic waves actually decrease, or increase your journey time? I suspect it is the latter. In other words, only generous people will increase their own journey time, to decrease that of others... If only there were a few more people like this on the roads! Gav gavinhudson at hot mail dot com
[When busting traffic-waves, how can it affect your journey time at all? Seriously. If you think it signficantly changes your journey time, please explain why. Ideally, all you're doing is to first determine the average speed of stop-and-go traffic, then second, driving at the average speed. In the ideal case, whether you participate in the stop-waves or not, you'll still go at the average speed.
But for more complicated moves, we can look to the truckers for philosophy. Truckers are a small community. They all want to go fast through congested cities. So they execute a move known as "reciprocal altrusim" where one member of the group clears the way for others who follow, and over many years the members take turns clearing the way. It's not pure altruism, instead it's selfish! But it's not pure selfishness either, because if truckers were selfish, none would volunteer to speed up traffic by taking the trouble to bust up the clogs of commuters. In reciprocal altruism you would try to bust up all traffic jams you encounter. But you'd also find that traffic was already flowing much more smoothly than normal, because some other reciprocal altruist had taken their turn being the jam-buster before you even arrived on the scene. On the other hand, if you want to be a cheater, and benefit from the work of others but without taking your turn... then maybe we should ALL become cheaters who sit and wait to reap the free benefits. You'll wait a long time in a society where True Altruists are almost nonexistent, and where reciprocal altruists have all decided that it's better to "avoid paying dues" and just put up with huge traffic jams. -billb]

Hey Bill! Fascinating website ("of course it is!" he thinks), of particualar interest is your article on traffic waves, a subject i have studied for over 25 years as a professional driver. I drove "b-train" fuel tankers for many years, and with a gross weight of 140,000 lbs they present an excellent opportunity to gain empirical data on these observations. I was curious about "standing waves" in traffic flows for many years. As you correctly state, drivers who take a competitive attitude to driving cause many problems and delays in traffic flows. I wrote our minister of transport many years ago with some ideas, he replied with a booklet of traffic stats and a terse note stating the obvious : that most accidents are caused by poor driver attitude and not necessarily lack of skill. Notwithstanding that, driving is a learned skill and my many years handling large heavy vehicles has given me appreciation for the subtleties of road management, subtleties that completely escape the average motorist. What particularly interested me were your strategies for minimising the impact of these traffic anomilies. As you said, truck drivers have been doing some of these things for years, such as reducing speed when approaching a standing wave. It actually does save fuel, time and aggravation. I, too, am a fan of Seth (since 1980) and many other things that could be considered out in left field.

How can you increase the amps, and current in static electricity to let's say!? Fire magnets!? I understand a Van De Graff generator can produce up to 400,000 volts at like 10 milliamps! But that is not going to make electromagnets work huh!? I need more current, and more amps!

Hi, I'm writing from an independent publisher where we are preparing a middle-school text on the history of science. We have a section on Bernoulli and airflow, etc, which includes the same picture of the Cessna coming out of the clouds that you have at /wing/rotbal.html. I thought you should know that this is not a "live" photo; it was produced for a Cessna ad by overlaying a stock photo of the plane on top of the cloud photo. So although the Bernoulli effect apparent in the clouds is really cool, it's not quite legit. Anyway, I'm adjusting our text in light of your helpful explanations here. Thanks very much.

I got your email address off a web page...thought you may be able to help me.
I am looking for a light box, original built by both
sharper image and Radio Shack in Mid to Late 80s.
Heck, I would
even be interested in trying to build one. Maybe by my description you
could either comment on how difficult if would be to build, or if you have
ever seen the item I am asking about. Or possibly direct me to where I
could find the schematics and parts.
16" square box, 3-4" deep
front of the box is clear plexi or glass
inside the box is a led panel approx 2" x 14" long
panel contains atleast 100 individual LED lights of different colors
the LED panel rotates at constant speed when plugged in
cord also connected this box to a stereo system
The result, when
plugged in was that each song played thru this box emitted a unique and
intersting light signature, also looking like kind of a wandering raster
image when connected to sound source.
any thing you can think of?
Maybe a suggestion where I could post this similar email for feedback
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!
