Actually, whatever plane the President is on is called Air Force One, no matter if it's military or civilian. Even if it's just Uncle Jethro's Piper Cub, it's still called Air Force One while the President is aboard. The only exception is if the Pres. is on one of the US. Marine Corps helicopters assigned to White House duty, it's called Marine One.
When the President is aboard a military aircraft, state the name of the military service, followed by the word "One."
When the President is aboard a civil aircraft, state the words "Executive One."
You continue:
There is no "Navy One" for ships, or anything like that.
Of course not, this is a communications protocol for aircraft. You stick the President on a Navy aircraft, and it will be referred to by ATC as "Navy One".
The reason you never hear about anything other than Air Force One is that the President doesn't fly on anything else.
...physics, and almost any form of engineering are all abstract arts. We deal with invisible quantities that do magical things that have no correlation with reality.
Physics is fundamentally about describing the real world. Engineering is the most concrete field of study there is (pun intended). If either of these failed to correlate with reality, they would have no purpose.
As for materials, any modern materials will last a long long time if properly maintained. Houses built of wood 100's of years ago are still standing and our wood products now are much stronger/better.
Remember, you're not seeing the 100 year old houses that were poorly built, because they aren't there anymore.
Actually, a lower pressure means a
higher boiling point.
I'm sorry, thanks for playing. Lower pressure means lower boiling point. The popular example is that on top of Mt. Everest, where atmospheric pressure is low, water boils at roughly 75C. You can barely boil an egg on top of Mt. Everest, but when it's done, you can reach in and grab it with your bare hand.
Actually it was a GOOD day for the earth as it got a major influx of material and upped its accretion rate, helping out in the race to be the biggest object orbiting the sun, though it still trails several other bodies, as of this writing.
By the time of the Chicxulub impact, that race had already been decided for a few billion years.

Because some moons are larger than Pluto... would they be considered planets?
I think what the poster was getting at was that if we all started running west we would eventually have to walk back home. This walking back home would reverse the effects. The only way that it would work would be to not go back home or to run completly around the world.
Conservation of angular momentum.
You will only have an effect on the Earth's rotational speed while you are running. When you stop, everything goes back to rotating as it was.
That's classical kinetic energy and is WRONG. You forget the gamma factor.
Even at orbital speeds, gamma (sqrt(1 - v^2/c^2)) is still so close to 1 as to be irrelevant.
SIGH. And we're supposed to be geeks?!
A real geek would know that gamma doesn't become terribly important until speeds are much higher than 17k mph. A real geek would also have seen that Aesculapius's example was completely wrong.
Borg vs. the Vorlons. This actually could be moderately fascinating...
Borg: Resistance is futile. We wish to improve ourselves. We will add your biological and technological distinctiveness to our own. Your culture will adapt to service ours.
Would not a sphere of unimaginable size have a surface that would essentially flat?
That's why the cosmologists have had such a hard time figuring out what the universe is shaped like. It's so flat and so big that it is very hard to tell.
However, a flat universe, and an unimaginably colossal (hyper-)spherical universe would cause slightly different phenomena to be observed. This new data has allowed the cosmologists to make their predictions with a better chance of being right.

The FAA disagrees with you.

Be careful what you wish for.
I found copies of both the crash sounds, and the startup sounds here. I recommend the 'Crash Mac Quadra' file.
Last I checked, dictionaries weren't legally binding.
"If it ain't broke, fix it until it is"
No?
That's probably why.
A newton is defined as 1 kg-m/s^2. As the AC already stated, you're off by roughly a factor of 100, and even that isn't exact.
ITYM mass. SI has no unit for weight. There's the newton for force, but it is not defined in terms of gravity. It is also not a SI base unit.
I haven't read What Do You Care..., so I'm fairly sure I saw it in Surely You're Joking....
I remember reading the passage in Surely You're Joking, Mr. Feynman!, where Feynman describes his experiences on a state textbook committee.
The short of it is, committees don't work for K-12 textbooks.
Physics is fundamentally about describing the real world. Engineering is the most concrete field of study there is (pun intended). If either of these failed to correlate with reality, they would have no purpose.
The acting would certainly be better.
Cooling the processor below the dewpoint of the room air will shorten your processor's life. Water does not mix well with electronics.

I think you missed the most important comparison to support your claim:
Mercury: 4880 km
Ganymede and Titan are both larger than Mercury. This is important because there's no argument about Mercury's standing as a "real" planet.

YHBT. YHL. HAND.

Yes. However, they will have gone through several more name changes by that point, and will be known as VA Sausage and Smoked Fishes.
To mangle an old joke, I think that putting one McDonald's at the bottom of the ocean would be a good start.

Vorlons: No.

I had a friend who used to think that.
Then he wrote an order processing system.
