>very computation-intensive This is a gross understatement and fallacious. Many of the problems being studied today would take millions/billions/trillions of years of computation in order to model... with approximations. Usin

I thought the goal was to have a self sustaining reaction that would only require laser pulses to hold it in place. Is a continuously pulsed laser necessary to provide thermal energy to drive the reaction? Also I've read (sorry no cita

Finally someone that's actually in the fusion field. Could you say whether or not the NIF research represents a practical path towards a fusion based power source? My understanding is that it would at least be capable of capturing some

I suspect these boards are being released in response to the rasberry pi, although I can't say for certain they're an appropriate replacement. Besides its not as if they're ending the old line of arduino boards, so if you do

There have been hundreds (maybe thousands?) of independently operating research groups at Universities and government labs, working since the 1950's all of them studying fusion. None of them has come as close to attaining controlled s

Do you have any evidence to back this up? Off the top of my head I can think of several dozen large successful projects, everything from the Mars Rover to CERN's LHC to the great wall of China and the Pyramids. These were all enorm

Yes, that was poor wording. I meant to imply it is often difficult to graduate debt free for STEM majors as well. TA stipends simply aren't enough to pay the bills these days. I don't mean to imply a STEM major is more valuable

The world for a graduating History PhD is totally different than for most STEM majors. Very very few History PhD's get their tuition paid for and are typically hugely in debt upon graduation. At least in the sciences its /possibl

He's not mocking the name or the finding, he's mocking the press coverage. This seems clear to me from the opening paragraph, maybe I'm missing something?

It is 100% a joke. He seems to be pointing out that you can get the press to over hype a scientific/mathematical advance by giving it a neat name, e.g. dark matter, anti matter, god particle, quantum-anything, electro-anything, super-

The beauty of open source development is I can do it in my free time, and because I want to. Often times having open source development on your resume is simply a way to show you're a motivated developer and to demonstrate the quality

It always shows last names for me (so long as they're available). Unless you've got some new feature, I'm guessing those contacts just don't have full names assigned. Spending some time in the "contacts" tab,

The simplest method would be to add a short range transmitter to the charging device. You don't have to limit yourself to using the charging technology for that.

I've heard the palm-pixi charging stand (which can be easily hacked to charge many other cell phones[1]) gets roughly 70% efficiency. [1] http://hackaday.com/2013/06/19/adding-wireless-charging-to-a...

It would be trivial to build in a sensor that detects when a device that needs charging is within range.

The mutual frustration imposed in PRDs is due to how it cools and the mechanics of a bulk state (tension on the surface and positive pressure in the core). What they're talking about in this paper is a chemically reactive state which i

The study is entirely based on first principles simulations. So even though these may be the most accurate calculations we can possibly carry out... they still may not be experimentally validated (for any number of reasons). In this case t

That seems like a pretty optimistic estimate, but I suppose its a guessing game for such a hypothetical system anyways. Also, for comparison BART ridership tops up at over 100 million a year[1], and 6 million fly between LA and SanFran ann

But that's at a pressure of 100Pa (1/1000 atm). How much power does it take to maintain a vacuum of 1/1000atm in a tube hundreds of miles long? It seems this point is skipped over in the whitepaper, so perhaps its negligibl
