Having taken a Unicomp apart, there's definitely a steel plate in the bottom.

Or get a micrometer or vernier caliper and just measure it.

They're only lifting extra mass on the first stage, not the payload. So it doesn't have to move the extra mass as much.

For rooted phones, the Cryptfs Password app (Or any terminal emulator app) can be used to change the device encryption password without changing the unlock password. The encryption password is only needed on bootup, so be sure you have a way to quickly shut the phone down (lockscreen widget, customized power button long-press, etc).

That's just due to the dilemma set up in our brains every time we try to cook: Do we cook the potato, or turn it into vodka and drink it? Do I make this wheat into bread, or beer? Add this barley to soup, or make whiskey?

Ionizing hydrogen DOES break apart the molecules. The molecules are held together by their electrons, removing those breaks the bond.

Heisenberg's uncertainty principle is just an application of the Fourier uncertainty principle to the quantum position and momentum wavefunctions. Since those are a Fourier pair, the Fourier uncertainty principle applies. So it's not a matter of which interpretation you pick, it's about whether QM is correct. If the behavior of quanta is not wholly determined by their wavefunctions then QM is wrong, and Heisenberg's uncertainty principle might be violated, since the true functions for position and momentum may not be Fourier pairs. This is widely considered to be extremely unlikely. Also, if spacetime is quantized (there's a minimum possible distance and a minimum possible time, and all times/distances are integer multiples of these minima) then the wavefunctions wouldn't be continuous, so the uncertainty principles might not be applicable. Loop Quantum Gravity is one theory that posits this.

Nope, though it's confusingly worded.

C, C++, JS, etc, have more instances where someone committed a fix for a bug (as opposed to new code).
Clojure, Haskell, etc, required fewer bugfix commits.

In an extremely general sense:
Somewhere in the program the validation code will either pass or fail. This is done with a conditional branch instruction in the assembly. Crackers use a debugger to find where this branch is, then change it to an instruction that will always branch to the pass condition.

Of course there are countermeasures used, and sometimes crackers will be able to reverse-engineer the validation check to create a keygen, etc, but the general process is still to disassemble the executable and modify or inspect the validation check.

It can work both ways, but in the case of aircraft motion sickness it's most commonly that you feel motion but don't see it. Any disconnect between vision and inner-ear can cause motion sickness.

Yes, I was somewhat careless with my phrasing. Any disconnect between the inner ear's acceleration sense and that received from other senses can cause motion sickness. On aircraft, for most people (AFAIK), it's caused by feeling the acceleration with the ear and not seeing it with the eyes. For some, it gets reversed: they see too much movement out the window compared to what they feel, and so do better with aisle seats.

Other way around. It's when you sense an acceleration (inner ear) but don't see it that you get motion sickness. That's why looking out a window helps.

Yep. If dark matter only interacts via gravity, and not via any of the other forces, then these results wouldn't constrain it. It would also mean that it's not going to be directly observable any time soon, so most scientists hope that's not the case, but it's certainly a possibility. Sterile neutrinos are one possibility for this.

Git is the best repository because it's the easiest to insult when something goes wrong. "Stupid git!" is a lot better than "Stupid CVS!"

You should try it with a lungfish. They're smart enough to breathe.
