| Posted: 03 Aug 2019 02:55 AM PDT During the Jurassic stage, was Pangaea a thing or was the continents separate? And if they was where certain dinosaurs only native to selected geographical locations? Also did dinosaurs evolve like we did and is there any evidence of this? [link] [comments]  |
| How is the amount of mixing quantified in a mixed quantum state? Posted: 03 Aug 2019 05:41 AM PDT Consider a system of 3 qubits. Then the highest mixing allowed by the 2-qubit reduced density matrices is them being equal to the identity in a two-dimensional subspace. How is the amount of mixing determined in a mixed state? I know a two-partite state is maximally mixed iff all coefficients of the convex combination of pure states are 1/n (n being the dimension of the state). But when is a non-maximally mixed mixed state more mixed than another non-maximally mixed mixed state? How does one determine the highest mixing allowed in such a system? [link] [comments]  |
| In what ways does Game Theory account for irrational actors? Posted: 03 Aug 2019 05:33 AM PDT My understanding of Game Theory is limited, so please feel feel to correct me on any of the following logic that leads me to my question: Game theory posits that, when acting rationally, every action in a given contest has an objectively-correct response. But how does Game Theory account for the irrational actor? Even just on a relative or "unofficial" basis? For example: I'm facing Kasparov in chess. He knows more than me about the workings of the game, therefore I'm less capable of rational acting than he is in our contest. Game theory would posit a certain set of actions, but I'm me and he's Kasparov. He'll probably follow what GT says he would do. I might as well be playing Jenga. Does Game Theory account for the fact that, compared to Kasparov, I am completely irrational? If so, how? Thanks in advance!! [link] [comments]  |
| Are band gaps experimentally measured or can they be predicted to a certain precision? Posted: 03 Aug 2019 02:05 AM PDT I understand what band gaps are, how they differ for conductors, insulators, and semi-conductors, and generally why they exist, though I not have taken quantum, electrodynamics, or modern physics, so my knowledge may be incomplete.

| What Does Rabies Do to the Brain? Posted: 03 Aug 2019 12:32 AM PDT I've Google'd around but haven't found anything exceedingly clear. Does anyone know, once the rabies virus travels from the peripheral nervous system to the brain, what it actually does there? Is this an area in which our body of knowledge is simply sparse? I came across this article which provides some insight. https://news.uaf.edu/research-may-reveal-how-rabies-induces-specific-behavior Namely, it shows that the rabies glycoprotein binds to and disables nicotinic acetylcholine receptors in the brain. Similar to what it does in muscles. But I'm looking for more detail on how mechanisms like this, or anything else that the rabies virus does, actually induce aggression, hydrophobia, and behavioral changes. [link] [comments]  |

| Posted: 02 Aug 2019 11:10 AM PDT In an article about the current problem of rapidly melting ice on Greenland, I read the following: "Up to half the surface of the island's ice sheet is thought to be currently melting, with runoff equivalent to a 0.5mm rise in global sea levels in July alone."

| Do fish "breath" heavier if they have to swim fast? Posted: 02 Aug 2019 08:48 AM PDT So we run for example we begin to breath heavy and fast as our muscle need more oxygen. Does this also happen with fish where they need to take in more water if they are escaping a predator? What about birds and reptiles? Now that I think about it I've only seen mammals breath heavy after running/moving quickly in general. [link] [comments]  |
| How is the insulin transfer into the bloodstream regulated? Posted: 02 Aug 2019 10:07 AM PDT I suppose you need to detect the sugar concentration?! But how and with which receptors? And is there some "holding back mechanism" in beta-cells or is just the insulin production reduced (by closing Glucose channels)? [link] [comments]  |
| What kind of metals are found on Triton? Posted: 02 Aug 2019 09:55 AM PDT Hi /r/askscience, I'm doing some reading on the different moons in our solar system and in the descriptions I've found of Triton it says that the surface consists of icy rock and "some metals". However, I can't seem to find any information anywhere on exactly what metals they're talking about and in what abundance the occur on the moon. Do we simply not have this information? That would make sense to me since we have sent limited probes that far out in our solar system. What's the word on this? [link] [comments]  |

| What exactly makes the sound when a lightning bolt strikes something? Posted: 02 Aug 2019 07:10 AM PDT Also sorry in case flair is wrong. Got a tiny bit confused. [link] [comments]  |
| What exactly does it mean when talking about the universe being flat or curved? Posted: 02 Aug 2019 07:34 AM PDT This is something I've never managed to get a grasp on. In laymans terms would it mean that if the universe was flat things would go on forever if you traveled in a straight line, and if it was curved you would eventually end up back at your starting point? But there's also an inverse curve or something too isn't there? [link] [comments]  |
| What factors contribute to how similar siblings look? Posted: 02 Aug 2019 11:12 AM PDT Is it mostly genetics between the mom and dad, random chance, diet, other external stimuli? [link] [comments]  |
