  • Radiation does not by definition make things it impacts radioactive, and most of the lingering effects that we associate with radiation have to do with radioactive particles that are left behind by the atmosphere. Since there is no particulate matter traveling between the sun and Mars (photons not withstanding), the surface of Mars would not be expected to acquire radioactive properties from an acute solar radiation event like this one. However, an entity on the surface of Mars would be exposed to radiation from the Sun, much more so than an entity on/near earth and it’s magnetosphere (Mars’ thin atmosphere and distance from the sun probably helps reduce that disparity relative to something in say low earth orbit, but I don’t think it fully equalizes or shifts the scales). I am not an astrophysicist, so there’s at least a 20% chance I got part of that wrong.

    Pi is an infinite series of non-repeating digits, and yet you will never find the letter A in pi because there is a 0% chance of the letter A being a digit in a decimal system. By the same logic, infinite possibilities do not guarantee that every conceivable state occurs, if that conceivable state has a 0% probability. As finite beings, it is very difficult for us to accurately distinguish between a 0% probability and a infinitesimal probability, so we end up circling back to “we don’t know”


  • Buses and trains. That, or spaghetti interchange that are bigger than the rest of the city. Also, replace key arterial roads with a pedestrian path, call that path a park, and charge $20 for entry. That will easily fund all the city services and nobody will be too inconvenienced by having to pocket their car as they walk across the “park” to get between neighborhoods. Now excuse me, I have to go murder a little blue bird that won’t shut up about the garbage piling up

    Based on the Wikipedia article on biological immortality referencing species that live for a couple hundred years and the Wikipedia page on armillaria ostoyae mentioning living specimens that are multiple millenia old (and thousands of acres large!), I’m guessing that may be what the prof is referring to?






  • Blower is specifically referring to coolers that are designed to blow air through the GPU heats ink and then out the back of the case. In contrast, open air coolers use (typically more numerous and larger fans) to force air at the GPU heats ink but without much concern for where it goes after that, so the air ends up partially blown out the back of the case, and partially recirculate back into the rest of the case where the case fans are hopefully promoting enough exchange that ambient temps remain sufficiently low. The recirculation is less than ideal, but is offset by the larger fans and heatsinks for a typically quieter and cooler solution. The fans can be larger because they are blowing on the larger side/cross section of the heat sink. Pass through are a somewhat newer variant of open air coolers common on newer Nvidia cards that push or pull air through a heat sink that is not blocked on one side of a pc so air flows though the heat sink with less back pressure for more efficient dissipation at the expense of a more compact PCB to put all the GPU components on
