Apparently he had a coil about 8 feet off the floor along the walls. Another coil placed at the same level would get current induced in it by the alternating current circulating in the loop. He published the work about resonant inductive coupling in the years 1891, 1892 and 1893. (Links stolen shamelessly from wikipedia.)
Unorganized individual home wi-fi owners and users on one size. Mega telecom companies with deep pockets full of government lobbyists, money and politicians on the other side. Both allowed to use the home wi-fi spectrum. You don't have to be Einstein to see what is going to happen.
There will be so much of interference with home wi-fi people will be forced to use mobile data. Or string cat-5 cables all over their homes to wired ethernet to every room.
Some parts of the ionosphere is named after him, The Heaviside Layer. But even there this Kennelly guy is muscling in to share the name. Poor guy, does not get a break.
You know it would be more efficient, and I would grant you 90% of the people know it would be more efficient if every one relaxed a little bit. But all it takes is a few to be bit more aggressive. And it will set the ball rolling towards everyone rush as fast as you can.
The starkest effect is seen in flights between India and USA. Most passengers would patiently wait their "zone" to be called while boarding in USA to fly to India. Almost the very same set of passengers would be lining up in Delhi or Mumbai to return. As soon as the first gate agent appears in sight, they all scramble to line up to board, rush the gate, crowd it and make it impossible for the gate agent to enforce any kind of order. The difference? The Indian Americans are constant in both flights. Subtracting out, the difference comes to a few Europe bound passengers boarding in USA and a few Middle-East bound passengers boarding in India. They make all the difference.
People obey the rules, if they believe others are also obeying the rules. If they see a few overspeed, others would too. If they see a few people cutting off autonomous autos others will follow suit.
Basically no one obeys speed limits. The posted speed limits are at best suggestions, and at worst revenue generators for the local governments. And many other traffic rules are casually disobeyed. Except for the stop sign, I don't see much voluntary compliance of traffic law. Stop after the white line at the signals, making a rolling right turn through the red light, 5 or 10 mph over speed limit within the city, 10 to 15 mph over the limit on highways are rampant.
Now throw into this mixture a fleet of cars, strictly obeying speed limits, preferring to slow down rather than speed up on yellow, refuse to use free right turns, coming to full stops on grade crossings... A few Access vans, school buses and trucks doing this itself annoys people stuck behind them in traffic. Now suddenly a large fleet of vehicles with a spinning dome on the head....
Also, in the game of chicken, the winning strategy is to appear be irrational. Break your steering wheel and throw it away in full view of the competitor, "I can't swerve, even if I want to, your move buddy!". All these cars are known to rational decision makers. They will be gamed like nobody's business. People will dangerously cut infront of them, be very rude to them, after all they are machines, no hard feeling. And every time the self driving car will slow down, yield, and let the barbarians get away with it.
In isolated test cases, in small numbers they will work. But large number of them interacting with large number of normal people, they will be forever stuck on the highway ramp or left turn yield on green locations.
It is very common to see T-shirts and mugs like these images saying And God said, {maxwell's equations in vector calculus notations}, and there was light.
Father of computational electromagnetics Zoltan Cendes, named his flagship product Maxwell(tm). He is the one figured out how to remove the null space of the curl vector from the computational solutions. Before that naively applying finite element formulation to Maxwell's equations yielded garbage. His edge-vector finite element formulation is the gold standard in getting computational EM results.
This brings up what Linus said recently. One would think Maxwell's equation was all "innovation".
But remember, Maxwell did not work in the vector calculus! He was working in analytical geometry, Cartesian coordinate system. Laboriously wrote out the expanded forms of the gradient operator and worked through the equivalent of the cross product explicitly term by goddammed term. I see Computational EM developers struggling to keep up with the math even with the use of Matlab and Mathematica software packages handling symbolic algebra. That he did it all in analytical geometry, for the first time, without knowing all the gibberish he was writing down will eventually lead to a breakthrough....
Is it possible other great mathematicians of his day had this idea? Probably. Some might have even pointed the direction to Maxwell himself. But, in the end, trudging through all that algebra and coordinate geometry in the long form laboriously is what made that breakthrough possible. Yes, innovation is needed as the spark. But, blood, sweat and toil contribute a lot more to success.
Not just testosterone. but also *all* snake oil remedies benefit ageing men. The snake oil hawkers are overwhelmingly ageing men. They benefit a lot. In fact, for many, it is their meal ticket.
They need to fire a few HR managers who fumbled and the higher level managers who pleaded for leniency too. That will send the message to the HR guys to do their job.
Buddy, why pick on science? Law does not accept supernatural explanation as defense. Why don't you religious nuts demand religious explanations to be given equal footing with forensic evidence in court cases?
Problem is Maxwell is the null space of the curl vector. It results in a rank deficient matrix, without unique solution. It wasn't until 1980 they figured out a way to subtract the null space and uniquify the solution. But that matrix does not have diagonal dominance. So all iterative methods are out. The condition number is very poor. LU decomposition is the only way out. And the unknowns are complex vectors. Not simple scalars like density, pressure and one real velocity vector for NS. Squeezing it all inside a GPU processor is very difficult.
One look at his website , it is clear this guy is a simple kook, hawking "ginger can cure cancer" or "yoga improves your SAT score" stuff. His claim to fame rests on the "inventor of email" and that claim is his meal ticket.
He cleverly won against a bankrupt company, which probably did not show up in court. He does not really have to win against TechDirt or anyone. He has already acquired enough blind followers who would shut out contradictory information, who are in the alternative facts realm. So he is in a no lose proposition. Win, he gets money and more credence. Lose, he would go back to "how big companies in big bad USA had stolen his invention and used high power and money to shut out a poor Indian immigrant". Either way his meal ticket is safe.
So he is going sue me now? For defaming his character?
They are not disclosing what that extra character was or even which language the code was written. As a coder I was interested in finding how it could have happened. But as it stands, it is a puff piece.
One char can make big different in performance and correctness. The greatest one character code change I made and got stunning performance improvement was adding an &. It took significant effort to find it, because instrumenting the entire executable for profilers was just out of the question. But once found it was trivial. The caller was passing a std::map by value. The answers were correct and the scaling effects were not visible till the map grew to big sizes. I expected to something along these lines.
For 120$ a month, I get four lines with unlimited text, voice, and 2GB of "high speed" data. Then it gets throttled to 128 kbps. That speed is good enough to provide turn-by-turn driving instructions. I don't stream videos. So I don't even use this much of data. Anyway if I am a security professional, the company issued phone would come with some decent wireless data plan provided by the employer.
Operation Quicksilver was a WW-2 operation by Allied Army stationed in UK. They created a fake army with inflatable tanks, and cardboard barracks and painted log canons. But the deception unit also sent thousands of fake radio traffic, drove a few trucks endlessly around to create fresh tracks every night etc etc.
We should kickstart some crowd funding to create a mod for android that recognizes a Quicksilver password. Once the quicksilver password is entered, the phone would unlock, but log in you with a pre selected account or mode. Everything there would be very innocuous, but enough stuff to make it appear normal. We might get some crowd sourced "safe browsing history" updated daily and very innocuous email traffic and very bland but seemingly very normal WhatsApp and SMS traffic with very recent date stamps. Some AI generated Mad-Libs like combinatorial content generator.
There should be a very special Slowsilver password that would turn off Quicksilver return the phone to normal mode.
The data plans have become very affordable. I don't find the need to ever use "free" wi-fi. I use wi-fi at home, and then it is the standard data plan from t-mobile. I don't even use the free wi-fi provided by my employer at work. ( No, no, I am not Visvesvaraya, the legendary minister of Maharajah of Mysore who kept two sets of candles and made sure he did not use the government issued candles while attending to personal work. Just simply privacy concerns, why even let the employer know my browsing habits? )
It keeps coming back. Massively parallel machine, thousands of cores all working in parallel. Naively multiply add up all the megaflops and get some massive number and tout it big. We can simply add all the flops of all the servers in some Amazon cloud and claim that is the super computer. Back in the 80s "transputer" was all the rage. Before that it was the "vector" computers. Then "the network *is* the computer", then GPUs...
As of now there are very few applications for massively souped up GPU processes. Fluid mechanics loves this GPU. Navier-Stokes is probably the most difficult equation to solve, agreed. But it is hyperbolic, with limited "zone of influence", and numerical equations are quite simple, just mass, momentum and energy balances in the control volume. It plays well in GPU, the calculations fit inside the teensy memory and processor. All time domain problems are hyperbolic and they all can be ported to GPU, theoretically. But try squeezing Maxwell's Equations into that teensy processor!
Graphics card companies are desperately looking for new markets and they keep pushing this. They might as well push a wet noodle across the table. It ain't gonna go nowhere it didn't wanna go.
There are tons of things not in the food, vegan, lacto-vegetarian, ovo-lacto-vegetarian nor in full red meat. Our bodies can synthesize, and do synthesize it.
Of course there are things we can't synthesize. Vitamin C for example. Most mammals can synthesize vitamin C. Only the bats and primates who adopted a fruitarian diet some 30 million years ago lost it. The entire gene factory to synthesize vitamin C exists in our DNA, but a key sequence is lost thus rendering it inoperative DNA.
But B12 is something we can synthesize. It is the gut bacteria complex that generates B12. B12 created in colon gets excreted and does not get absorbed. But enough gets created in small intestine, it is enough. B12 is very efficiently recycled by the body.

They tried with betamax, with some strange micro DVD, memory stick. They are sad they have to work on some industry standard.

All these are generally called steroids. Doping in sports fears are not all that exaggerated.
