| why can't there be no electromagnetic ion waves inside a plasma without an external magnetic field? Posted: 17 Oct 2019 09:20 AM PDT are these waves the same as an electrostatic ion acoustic wave and an ideal Magnetohydrodynamic sound wave? Is this because the external magnetic field can be created by the current formed from the movement of the ions? Why can such a wave exist with electrons? [link] [comments]  |
| How can software perform tasks hardware cant’t? Posted: 16 Oct 2019 09:53 PM PDT I was watching a lecture about assemblers/compilers and the lecturer at MIT indicated "what we'd like to do is build a general purpose processor that can run programs written in many high level languages [c, Python, Java]. Not only that but we want to be able to not make the hardware overly complex and support every feature in our high level language." How can the high level language provide functionality that doesn't exist in the hardware in some fashion? I've heard this before, that we want to separate software implementation and hardware implementation (or something to that effect), which I can't understand - somewhere someway there must be hardware doing what this language supports via the assembler/compiler/translator. The only thing I can think of is she's being imprecise and what she means is that the hardware can support all these high level language features, just not intrinsically - There is no machine instruction an assembler can invoke to make something eg "volatile" as in the c++ library, but it can build something equivalent from simple instructions that make up a RISC processor? That I can understand. Relevant lecture, in the beginning. [link] [comments]  |
| What is the exact relation between mass and electromagnetic charge in the scope of modern QFT? Posted: 16 Oct 2019 04:02 PM PDT Years ago I actually had several courses on GR and QFT (alas I forget most of it over the years) but why is it that all electromagnetically charged particles are massive. Is this a direct consequence of the symmetry breaking introduced by the Higgs field? I speak Lagrangians and Hamiltonians, you don't have to be gentle. [link] [comments]  |
| Is the moon topography shaped in any other manner than meteoric clashes? Posted: 16 Oct 2019 12:44 PM PDT Looking at higher quality moon photos, there seem to be mainly craters across it. However, there are some stuff that appear to be perhaps mountain ridges. This made me wonder, is the moon shaped only by meteoric clashes? Does it have any other forces driving it's shape? I assume there's no melted core and as such no tectonic plates shifting, but what about other possible factors? here's the high quality pic that got me thinking about this. [link] [comments]  |
| Where can I find a video of astronauts on a space walk that is NOT filmed with a wide-angle lens? Posted: 16 Oct 2019 02:44 PM PDT I watched over a dozen YouTube videos of space walks and they're always filmed with fish eye lenses. I understand they do this to capture as wide a field of view as possible but just once I'd like to see what the view from that high up would look like without the wide angle lens distortion.

| Is it true that as we get older, our brains will lose it's capacity to learn new skills? Posted: 16 Oct 2019 02:43 PM PDT ....Or could it be just due to the lifestle changes as we grow? Job/responsibilities/having no spare time/ etc ... ? Particularly i don't feel i like my capacity is affected on a neurological level, rather it feels like more as if my attention was focused on other things that being the reason for learning impairment on a later age. Anyways, curious about it. Thanks [link] [comments]  |
| Why do men have nipples? There doesn't seem to be an apparent function. Posted: 17 Oct 2019 09:30 AM PDT I think that it is because there is no cost for them having nipples and because there is no benefit in making the trait sexual dimorphous. But, I don't really know. [link] [comments]  |

| Why does Venezuela have so much more oil than any other country near it? Posted: 16 Oct 2019 03:38 AM PDT Why are oil deposits in south america mostly concentrated in Venezuela (90% of south and central american oil) while in the rest of the world is spread out over vast areas (for instance in the middle east large reserves of oil are spread over the arabic peninsula, Iraq and part of Iran) [link] [comments]  |
| Why does Addison's Disease/Addisonian Crisis cause Leukocytosis and Anemia? Posted: 16 Oct 2019 12:17 PM PDT I'm doing a research on Addison's disease. However, I truly cannot find the reason why it leads to Leukocytosis and Anemia. I don't need a study or a paper, I just want to understand what causes this change? [link] [comments]  |
| Are transdermal patches more effective on certain areas of the skin? Posted: 15 Oct 2019 09:51 PM PDT Why do companies recommend the patch to go here or there. Do transdermal patches just need thin skin or do some areas of the skin accept medicine better? Or, are all parts of the skin equal. (Aside from callouses.) [link] [comments]  |
| Do good looking people have more risks of developing a cancer? Posted: 16 Oct 2019 02:35 PM PDT Not just good looking, but having characteristics of hypersexualization, like having a very feminine voice, for example, etc. [link] [comments]  |
