Except that GPS satellites are in MEO... and would be immune from the Kessler Syndrome which is a LEO problem...

Is it just me or are people *way* more interested in the shuttle now than when it was still flying?

Probably less long that it would take him to get into everyone in the audience's...

.. and whose job is it to maintain the list of which of the hundreds of thousands of consumer electronic devices comply and which failed? And do you expect the flight attendants to be able to tell the difference between every one? How do you implement this? Maybe a nice little (easily forged) sticker for the back of the device?

uh... but given long period of temperature fluctuations throughout measured history... wouldn't you expect a temperature change since the Industrial Revolution with a probability of almost 100% and a probability that it would be an *increasing* trend of 50%? Wouldn't it be more surprising if the temperature was exactly *constant* since then?

... how bout the fact that he couldn't solve that - but has a B.S., two masters degrees, PhD credits, and "oversee[s] an organization with 22,000 employees and a $3 billion operations and capital budget, and am able to make sense of complex data related to those responsibilities".

I simply can't reconcile the above with his inability to solve any of the 60 math questions.

I'm thinking his degrees are utterly worthless and I'll further speculate that the organization he oversees with $3B budget is being grossly mismanaged.

he United States' "War on Drugs" is the root cause of all that violence in Mexico.

Funny - I thought the root cause of all violence in Mexico were Mexicans shooting and killing one another...

You must have a different definition of "free for all". I think you really meant "free for the student, paid for by everyone else"

The experiment was over 15 years ago so I'm not sure but I seem to recall they both looked rather pinkish-violet. Honestly - I don't know when I am seeing UV if at all... I would say though that the purple section of a rainbow looks thicker, and terminates with a pinkish-whitish-violet color that just sort of fades. I've always assumed that's what everyone sees regardless of where their sensitivity ends,... maybe I'm wrong.

I see UV too,... at least technically and I don't believe it is that uncommon. In a college quantum physics lab we were looking at the emission spectrum of Hydrogen and the instructor was guiding us through various emission lines. He asked if we could see the purple line and then asked who could see the *other* purple line. I was the only one who could. He said he always asks that because every class there are one or two students (out of about 20) who could see just enough into the UV spectrum to see it. I don't recall which line it was but assume it was the Balmer n=6 line at 397nm.

I can't say this has been particularly more useful to me although I do think I see rainbows as 'wider' than most people with a much thicker "purple" band than others seem to see. Totally subjective and something I can't substantiate but I think I am more sensitive to sunlight as well.

Green technology can be profitable, but it needs to be made practical. If I have a budget and see if I buy this expensive solar setup I'll get a return about five years or more from now then that just isn't an attractive option to most people. They want savings now, not later. I see news all the time about breakthroughs in making solar energy cheaper and more efficient but I've yet to actually see prices on solar drop when I'm looking to buy equipment for a remote setup. I don't agree with the government taking more money from people to prop up a business who's business plan obviously didn't measure up or they wouldn't need the help to begin with. If you want people to be green then make it economically practical for them to be so. If people don't have the extra income to go green is it fair to beat them with a stick saying they have too and taking more of their income so the government can give it to whoever is the most politically correct at the time?

I hope none of those guys are working on Windows 8. The story sounds like they have a years supply of whiskey on hand.

Right... you know where you see valid targets and just shoot missiles everywhere else and surely you'll hit the stealth target.... brilliant!

At first glance, that looks exceedingly like an F-22 (I'm no expert-maybe specialists here can point out differences)

I am - and to anyone else in the field the designs look nothing alike. The F-22 (and F-35) have a diamond-wing planform without canards with diamond vertical stabilizers. The J-20 has canards and a delta wing with swept vertical stabs. Take a look at this planform comparison
