This is a problem from my GMAT practice exam that gives me the right answer but not an explanation as to why. The question is formatted as a data sufficiency question, which means that it asks you whether a pair of statements would be individually and / or together sufficient to answer the...
OK, so I'm taking this GMAT practice test online, and I got stuck on this question. The software tells me the correct answer, but not the explanation. What I'm really stuck on is the wording of the question - it's been 10 years since my last calculus class, and even though it's an algebra...
My understanding is that today's computers aren't able to simulate true randomness, only complex functions that appear random but can be predicted if someone knows how they work.
Is there any way to incorporate the "true" randomness of QM into technology to achieve true unpredictable randomness?
Here's my thinking: The faster you go relative to the universe, the more the universe appears to contract. However, c remains constant as measured by distance/time.
Now, what about to a photon? To a photon, the entire universe would appear as a single point, correct? To this same photon, c...
My understanding is that when you measure an electron's spin on on Axis A, and then on Axis B, the spin on Axis A is "forgotten" and can be something different next time you measure it. Is this correct?
If it is, then how does this work across entanglement? If you measure electron A's spin...
A common concept used in the explanation of the twin paradox is that upon acceleration, one twin sees the other twin's time speed up. Is this correct?
Assuming it is, how would they observe a light clock next to that other twin? The light beam can't bounce faster, right? But (assuming a...
If you're on a spaceship that's accelerating at g (9.8 m/s/s), you would feel a force similar to the gravity here on Earth, correct?
Now what happens if you go off into space and keep this acceleration constant?
What happens as you approach the speed of light, which should take under a...
