There are 25 million people living in Madagascar! That’s halfway between the population of Australia and Canada. They have a GDP (PPP) of $40 billion. “There’s not 300,000 middle class homes in Madagascar” “Do they have a class system” “I’m pretty sure they don’t have a lot of people” “There’s a limit to how many people they let live on the island”
The answer to the special relativity rocket question is actually wrong. While it's true that objects that are Lorentz transformed from their rest frame are contracted and experience a slowing of time (in comparison to the initial reference frame they started at), that's not what the question is asking for. It asks what a specific observer would *see* once she looked at the rocket coming towards her. Everyone is probably aware of the Doppler effect, which implies that the image of the rocket would be blue-shifted, but some more nontrivial effects also exist, which happen to change the answer to the original question to B. To see why time must actually visually look to speed up, you can consider the clock to have a frequency of its own (say the number of times it ticks per second), which is also correspondingly Doppler shifted to increase, since the ship comes ever closer with each next tick; it turns out that you can mathematically show that the Doppler effect is more important than the time dilation. Similarly, the ship will actually look longer because it takes time for the light from the back of it to reach your eyes, so the image is retarded (the actual technical term, which is also used in general treatments of EM) and the ship elongated. It is tempting to equate the visual perceptions we have with the actual underlying nature of reality, but, unfortunately, such equivalences are rarely correct, especially once applied to relativity or quantum mechanics.
The answer that the quiz offers for the "expansion of everyday objects" question is also a bit iffy (but at least true in its spirit). Since the expansion of the universe isn't a force, there is no meaningful comparison between it and the strong interaction or gravity. The expansion can be explained through the premise that the universe started in a state where everything was flying away from everything else at an incredibly rapid rate (caused by a still unknown mechanism, although some inflation enthusiasts disagree), which was later affected by gravity, but there is nothing actually trying to rip things apart (well, maybe dark energy is, but that's a different story) no more than there is anything pushing a ball away from my hand once I've thrown it up. To see the scale on which structure formation happens, one can compare the local gravitational free fall time (something like a few minutes on the surface of the Earth) to the Hubble time (something on the order of the age of the universe) and decide which effect is likely to dominate.
Question 6 - The man falling in the elevator shaft was Neils Bohr. He yelled up at Einstein, "gravitational anisotropy bitch due to quantum....he got too far away."
I happened to watch this video right after your video about your GRE scores. When you took the GRE did you sort of not read the questions, misclick a few answers, and and have a random cat wandering around distracting you? It would explain a lot.
Question 3 - From copious research in optics, the photon only has a very negligible mass if one squints hard enough, so massless. The gluon has all three colours and self interacts, this along with the fact that it can channel spirits, obviously massless.
More than half of the questions were trivia. Most had little to do with actual physics knowledge, and the ones that did were extremely easy.. you can tell the person who made the quiz has no clue.
Everyone seems to have a different song that helps them to remember the order of the planets, but none of them even compare to the Blues Clues version.
at 3:00 you guys have muon and neutrino backwards - neutrinos are WAYYY lighter than electrons (and neutral to boot), Muons are heavy versions of electrons.
Question 5 - In matters concerning cosmology, we should apply economics or fiscal theology. Pareto would suggest that an 80/15/5 percentile rule might be helpful. So dark energy/dark matter/(anti)-matter. I need not quote Feynman about the amount of ZPE in a m^3 of space-time, so 80ish is a good first. Although the middle percent is cool, we really won't have a good order estimate until young ensigns aboard federation starships turn in cumulative data about dark matter asteroids while all the while their ship's captain....finally the third percent is based on stuff that interacts with EM directly.
more than 5 year after, I've come to say that I've got 12/15 (the madagascar one I just guessed it lol), the ones I've missed made me cringe with myself afterwords, but it is what it is
The relativity one is wrong. If it was moving directly towards her, she would see no length contraction. You only see length contraction if you have some component of your position perpendicular to the direction of motion.
The "LHC uses 1.3TWh" is messed up - Watt-hours is a measure of Energy but option a) is talking about Power. Edit: I guess you're supposed to use the energy consumed in a year, but it's not explicitly stated even though in options B and C it is. I guessed E anyway.
The first question was wrong tbh because mass isn't the amount of matter , amount of matter has unit of mol not Kg. Mass is actually the property of body by which force can be applied on it.
Question 2 - Piers Coleman of Rutgers is the only cat in the known universe that can logically answer this question. But appealing to stat mech (the best hiding place for common sense and route to major funding) I'd say "conserved."
