Except that Hillary is the one being given a free pass. She's quick to shift the focus of her own wrongdoings with the email server and DNC hacks to Trump (based on NO evidence) to distract from the DNC and her own evils.
AND - she makes it look as if Trump is in collusion with Russia, when in fact she is the only person who illegally worked with Russia and took bribes. I'll copy and past a comment from an AC poster from another article here:
Story [http://www.nytimes.com/2015/04/24/us/cash-flowed-to-clinton-foundation-as-russians-pressed-for-control-of-uranium-company.html] about how she received bribes for allowing Russia to buy 20% of the USA uranium production. She clearly stated how she wouldn't take foreign donations to her foundation while at state, would ask for a waiver to do it if it came up, and would disclose if it happened. She took the bribe, didn't ask for a waiver, didn't disclose it, and failed to report it on her taxes and had to amend them years later after she was caught. She showed "Intent" in hiding the donations because they were bribes. This isn't even questionable campaign donations, this is direct bribes to her for approving something the State Department wouldn't normally even consider.
I'm not sure why people bring up her email scandal. As bad as it was, it wasn't taking bribes from Russia for State Department favours while she was in charge.
How is she even possibly considered for the DNC nomination after this came out?
Right with you on this - never been a fan of apple products and only ever purchased a small iPod once. Isaacson's book was profoundly moving, it reads as if your by Job's side the whole time. Highly recommend anyone to read this.

You could make an argument about beating chess not being AI, but that argument wouldn't hold for Go. With chess you don't have to program "intuition", it's evaluation of possible moves. With Go the possible number of boards is obscene : around 10^800 possible boards, where there are ~10^80 atoms in the universe. You can't just extrapolate and calculate possible moves, you have to program a deep neural net with a sort of AI "intuition". Very impressive feat, and the South Korean government immediately dumped billions into AI on hearing about the feat.
The guys at EES just released a $10 app, though not free. There are also python apps. Another good one for quick calcs is Wolfram alpha. I agree there needs to be a great open source app with programmable functionality and saved scripts.
A Faraday cage wouldn't stop static magnetic fields; you would need mu metal or superconducting materials to help decrease the magnetic field of earth.
"And don't forget that these superconducting grids will be dangerous as hell, if you're pushing enough current through a cable to power north america and any part of the cooling system fails the resistance goes from zero to anything non-zero and your superconducting cable explodes extremely violently.
I'd agree these superconducting cables have issues, but exploding really isn't one of them. Most modern superconducting magnetic coils and cables are designed around quenching and have copper dump loads built into the cables. The real killer for power is the energy required to keep the cables cool...
IMHO, the solution to solar would be affordable large scale energy *storage* (magnetic energy storage, large vacuum composite flywheels, etc.).
The AFMs you cite only use stepper motors for the first stage of precision movement. The precision movement at the atomic level is handled by piezo devices (i assume called piezoelectric actuators). These are very difficult to control since they have complex hysteresis involved with their movement, and change their properties over time. Expensive as well. He *is* better off using the hard drive components to do what he wants...
Polywell more wacky than this? There are a number of things I can't see them getting right with this piston concept any time soon. Personally, I don't think they can make a uniform shockwave using pistons, but we'll see I guess. The plasma vortex rings sounds interesting. I guess my primary question would be using the lead lithium blanket next to the plasma. Invariably, you'll have some vapor in the plasma region, and these higher Z atoms should wreck havoc with Bremsstrahlung radiation. The polywell already produces neutrons from fusion, avoids Bremsstrahlung more than the original "fusor" concepts, and should be scalable. Granted, I actually feel that the more conventional schemes have a greater chance of success currently. ITER should break even...
Exactly - the magnetic confinement for a fusion torus is already completely closed. With a torus, as I understand, there are issues with plasma stability that limit the performance of the devices. However, there is no need for this light looping when you can just alter the magnetic field. Stellarators use a sort of 'helical' magnetic field twisting around a toroid to create a much more stable environment. See: http://www.physics.ucla.edu/icnsp/Html/spong/w7x_with_coils.JPG.
I did some research for school over in Hong Kong for a few months and worked with the Hong Kong Polytechnic University Civil Engineering Dep. They used titanium dioxide coatings on bricks and highway noise barriers - actually in use in Hong Kong. They also have attached titanium dioxide nanoparticles to textiles to make filtering clothing:
Also, I don't mean to claim that the fluctuations in the liquid helium itself can go above superconducting, but just anything at all. I don't know how these failures happen, but the temperature does rise and they do. Perhaps the forces from the magnetic field might push some strands against a wall and then gradually warm up, or some other mechanism. The point is that quenches do happen and the cable must be designed around it.
Two weeks ago I visited the team designing the ITER superconducting magnets, and that was what they told me. From what I understand, even though a quench is unlikely ("HIGHLY improbable" if you wish), if one happens it is still a catastrophe. Using the copper surrounding the superconducting strands with high speed circuits and you can save your cable...
The superconducting cables may still have some temperature fluctuation which takes a small part out of its superconducting state. When this happens all that current suddenly becomes ohmic and the cable is potentially destroyed (quench). They design in regular cable strands (copper usually) which can carry this current for a split second until circuits turn off the entire cable before it is destroyed. Otherwise you're hoping your cable remains perfectly cool, and if it fails you have to replace millions of dollars (at least) of superconducting cable.
I don't know about anyone else, but before I opened this page I expected most of the comments to be a little 'careless'. This has nothing to do with the nature of the event but the nature of the internet. Do yourself a favor and read through the Youtube comments of any popular 9/11 video.
Of all the comments here that I've read so far your comment worries me the most. Even if this is not what you expected, you're judging an entire nation on a few comments you read on this site? I'm positive a nationwide poll (not on the internet) would show above 99% of Americans have heartfelt sympathy for the Chinese from this event. The minority that don't, for some reason, are also the most vocal and ruin it for the rest of us. Myself, I wish there were something I could do rather than have to sit and watch Youtube videos of the event.
I didn't mean to say this wouldn't be susceptible to creep - all polymers are to one degree or another susceptible to creep. You're right that in this case creep should be more pronounced. The degradation, of course, I would expect to be far less....

Eh, Goddard quickly learned that didn't work and went on to make this:

Where Goddard failed apparently was in his paranoid insistence on secrecy.

First time I heard a professional needs a PhD.
I imagine it would be more like finding a copper smelting pit and then some used tools - all cool stuff right?
... "why are people with trait XY not applying?"
Actually, I think it is those with trait XX that are usually misrepresented?

The correct answer is "Yes. I will take that bet."
