EM waves do induce currents, that's how radio reception works. But EM waves are not used for inductive charging, because of the obvious waste of energy.
Inductive chargers involve what's basically a transformer in two parts: one coil (the charger) is used to generate an oscillating magnetic field, which induces current in another coil (the phone).
EM waves/radiation are a rather special case where electric and magnetic fields oscillate together, basically inducing each other to make the wave go on. But you can have oscillating fields and induction without the EM wave mechanism.
I have a master's degree in physics so I could probably explain a thing or two about the differences between EM waves (radiation) and inductive charging. Or maybe you could look it up somewhere like Wikipedia, instead of spewing around any inaccurate emissions.
I'm pretty sure these charging mats use some kind of induction, which doesn't spew EM radiation all over. Still more wasteful than plugging in, though.
I don't really understand the benefit of these, since it won't reduce cable clutter around your desk. I guess one might make sense if one charger replaces lots of small ones in a workplace etc. Otherwise, it sounds about as useful as a Wifi AP that only works within touching distance.
This. I remember when 1 BTC was worth less than 10 c, and I wish I'd bought some back then. I also remember when it crashed to about $2, then later to $100, then to $400, and so on. It's a strange variable if it can keep crashing/decreasing all the time, yet have local minima at ever increasing values.
If you look at stock prices or anything similar, you see a fuzzy fractal-like curve with ups and downs all the time. You need not worry about every single downturn if you look at the big picture. As Homer might say: coin goes up, coin goes down. Coin goes up, coin goes down. Hehehehehehehehe.
Prime numbers are essential to modern cryptography, so it makes sense for the EFF to fund research into primes. While the newest Mersenne primes aren't readily necessary for cryptography, there's a lot more to the research. For instance, someone might discover a better way of predicting the distribution of prime numbers, which would make prime-based encryption weaker.
I was also thinking, where's the source code, or at least some description of the algorithm. This is a tech site, for hug's sake. I imagine it's yet another application of machine learning where nobody really knows how it actually works.
In many ways, modern computing started with the Jacquard Loom, which was a technology to mass-produce digitized pictures. Today, it looks like the most important application of computers is posting pictures of one's posterior. We've gone a full circle, and in the process ended up staring at our own behind.
Nokia had management issues long before the Elop flop. In the early 2000s, Symbian was starting to show its age and limitations, but upper management held on to it and they had to make that hasty Windows decision when it was too late.
Their first Maemo device was released in 2005, but they didn't have one with cellular connectivity until the N900 in 2009, they were Wifi-only tablets until then. I presume the limitation was partly due to the Symbian management. Around the same time, a small Finnish company (I forget the name) was developing phones/tablets that were even further ahead of their time, and they ended up selling some of their tech to Apple.
Are these things being sold in the south Asian countries where almost all of the ocean-going plastic waste is being dumped in the rivers?
I don't know, but producing such throwaway electronics doesn't help anyway. Also remember that a lot of our e-waste ends up being "recycled" in third world countries.
Now, what I'd like to see is a way to use generic Linux on these consoles. Since you cannot install new games via official channels anyway, Nintendo/Sony have nothing to lose, only goodwill to gain. After all, they are using a ton of opensource software, including the emulator in the PS Classic. You can probably get equivalent, open hardware for less, but not necessarily if you count the case and the controllers.
The S?NES Classic and the Playstation Classic are indeed just Linux machines running emulators. I guess this is the next stage of the "app" culture: instead of selling software, sell a new "app-liance" for every separate feature. The oceans will thank you.
It's different from traditional banking, though, because Ethereum users themselves agreed to the bailout, and it wasn't really forced. The original chain does continue as Ethereum Classic, but it's a much smaller player.
It's not just the number pad. A lot of laptop keyboards are simply badly designed, the space is being used for the wrong(TM) things. Thinkpad keyboards used to be great with a clear set of Home/End/PgUp/PgDn and large Esc/Del keys, I'm not sure if they still do. While Apple does put the typing area in the center, they hardly have any usable arrow keys or the aforementioned ones.
Old PC keyboards had Home/End/PgUp/PgDn on the number pad when NumLock was off. So a number pad wouldn't be all bad if they just used it properly. Now, they put these keys on the arrow keys via Fn, which is just really cumbersome in practice.
Interesting. I was wondering why they should bother with nice whites in the backlight, when it gets filtered by the RGB anyway -- why not use specific R/G/B LEDs instead? But it seems we can't make them specific enough.
I am interested in the backreaction conjecture, according to which structure formation would lead to the observed larger expansion rate and longer distances without the need for dark energy or modified gravity.
Not quite your multi-big-bang theory but similar elements wrt dark matter/energy. And something that's being studied by professional physicists around the world.
I'm not familiar with the multi-big-bang theories (I've only seen some headlines) but I have some understanding of the classical idea. Basically, we're inside the ongoing big bang, and it looks like a black hole to the outside. There are probably a lot more out there (see this book for one fun idea) but they would be fundamentally out of our reach.
(I have a master's degree in physics and I did study proper General Relativity, but I haven't had much of a research career, at least not in cosmology.)
What about supercomputers? They are great, right, except they are basically huge calculators, so it's not like a huge win in my book. Besides, *BSD could have been used there as well.
All computers are basically huge calculators. Supercomputers set a great example of Linux dominance, because you really want to use all of that expensive hardware for your calculations, instead of it being dragged down by an idiotic OS and spyware. (Linux has much better hardware support than the BSDs, so it's an obvious choice for people who need to make the most of their hardware. I guess the BSDs have a more natural niche at the security conscious servers.)
Traditionally, mobile computing was severely limited by hardware, so Linux was a similarly sensible choice for making the most of it. However, today's phones are looking more and more like corporate desktop machines where you can waste gigs of memory and a handful of CPU cores for shuffling a little text and images around. In both cases there's a similar rationale for the excess: using hardware as a status symbol. Linux is cheap and efficient, but many people buy an Apple just to show that they can afford an Apple.
I think you misspelled "coproration", which refers to pieces of excrement handed out to the poor unsuspecting masses. https://en.wiktionary.org/wiki...

Ah, nuclear reactors with the stability of Windows...
Begun, the clone war has.
Can't agrue with that.
Wasn't GPS the original system, thus making the others.... clones?

Terminals are no longer considered "dumb" or "smart". All are equally valuable.
Relational math operators such as < and > are no longer allowed, because all numbers are equally valuable.

Eight stories of wood were finished around here a couple of years ago, and I think they've already built a few more. https://www.woodarchitecture.f...

Quoting one of our most famous physicists:

Yes. I majored in physics, and I find this theory utterly repulsive.

So in this sense they cloud technology symbolizes "heaven".
