That's just mean :tiphat:

An extrapolation from lifetime experience of perception of 1.5eV range, meters sized objects and g accelerations (a.k.a. common sense) can not be valid argument against phenomena on TeV scale radiation, femtometer setting and extreme space-time curvations. No matter how great authorities were...

No one ever called Newtonian time independence of space a deep and powerful principle and I challenge you to prove me wrong. Composition of configuration space is just postulated. Furthermore, I absolutely decline your assertions, as if anything humane contaminates pure science. Like it or not...

Until independent measure confirms this, I'm on skeptic side - it reminds me of a situation in particle physics; conservation of electric charge is much less experimentally proven than conservation of baryon number. Nonetheless, bunch of people are on the hunt for baryon violation and virtually...

I can't wait to see how will they reconcile this secret mission and it's Russian counterpart, scary aliens, government conspiracy and the fact that we never actually went to Moon :) Definitely - a must see!

I think this is what you are after.

Meanwhile, in Croatia ... Here, to get a firearm (automatic rifles are banned), you need submit to a medical exam that includes a psychiatric tests. Also, permit may be decline due to certain criminal convictions. These strict conditions were imposed to reduce piles of guns, ammunition and...

I'll go with safe. As for Fukushima, root of trouble was a massive earthquake combined with flawed design of reactor which was knows as early as 1975. So, I'd say bureaucracy is not safe, saving money on staff training is not safe. If there were such an earthquake at Three Gorges Dam, God...

Those coordinates point to middle of Atlantic Ocean. I consider my missions failed when I land there ;)

"Use of weapons" Iain M. Banks

Although I though you nailed it, 'couse Google picture search on "hydrogen plasma" has a number of pink plasmas, but blue ones appear too. Also, in astronomical pictures, hydrogen is always pink. Anyway, I don't think you are far off, but this "blue" problem may be interesting to look at - I...

Ok, you got all the ingredients to take a reasonable shot at this. Do note that you may add any constant to \epsilon(n) = C - 13.60569193 eV/(n^2) so you can handle numerics easier. Good luck!

Well, it's not a small feat to derive color of heated hydrogen from first principles. I'd rip off color photo of NERVA burning or just make it up :) Anyway, I did some thinking and this is the way I'd handle this. First, what temperature range are we talking about? If it's >5000K, we are talking...

I found a really cool article related to L1 Lissajous curves and transit trajectories. +1 Berkeley&NASA! I think you'll enjoy it.

Well, I have a degree in physics with diverse interest, so I'll toss my opinion: bronze medal would go to topology/general relativity. Always treading on mathematics, only sometimes achieving tantalizing "direct" insight. Silver medal would go to organic chemistry. I took a course in it and ever...
