| How deep or shallow can the sand be in a desert? Posted: 25 Apr 2018 07:54 AM PDT I mean not standing on a dune, just standing on fairly level sand at whatever average altitude from sea level any given desert is, how far down can the sand go? Can it be very deep or just a few inches before you hit different material? Does it vary greatly from one desert to another? [link] [comments]  |
| Posted: 26 Apr 2018 03:39 AM PDT Just wondering how a very detailed pattern can be filled with metal (such as copper) in such a small scale (in nanometers). Surely molten copper will not work (that's just my assumption with the basic knowledge I have). Please enlighten me. [link] [comments]  |
| Why do clouds have distinct edges? Posted: 25 Apr 2018 08:03 PM PDT I understand that some parts of the atmosphere contain more water vapor than others. But shouldn't the boundaries be gradual and diffuse? Tobacco smoke, for example, quickly spreads and dissolves in the air, so why don't clouds? [link] [comments]  |
| Does antimatter visually look the same as matter? Posted: 25 Apr 2018 08:25 PM PDT If I saw, say, a chair made out of antimatter, would I be able to tell it was antimatter just visually? Also, since we usually don't "touch" things due to Coulomb repulsion, would a bulk material (say a plank of anti-wood) pull us towards it when we try to sit on it? [link] [comments]  |
| [Earth Sciences] Why can't they "tap" the gas coming out of the burning "door to hell" pit? Posted: 26 Apr 2018 05:39 AM PDT This thing has been burning for a long time: https://news.nationalgeographic.com/news/energy/2014/07/140716-door-to-hell-darvaza-crater-george-kourounis-expedition/ Why can't they drill down near it and start capturing all of that gas? Is it not worth it? Is it not possible? If we can put our burning oil wells, why can't we put this out? [link] [comments]  |
| Posted: 25 Apr 2018 07:05 PM PDT I am learning more about how the brain uses ions in order to send messages and how proteins work together as a whole in order to create thought. What I am curious now is if there would ever be a way to convert electronic signals into protein signals. Also as a bonus question, can directly injecting neurotransmitters through the skull affect the rhythm of the brain or the consciousness of the brain ? [link] [comments]  |
| Posted: 25 Apr 2018 05:31 PM PDT Over millions and billions of years, I would assume the earth got heavier/more mass as meteors, asteroids and comets landed here. Would billions of years of radiation from the Sun increase Earth's mass? Does Earth's mass increase over time? If so, what does that mean? We gonna move closer to the sun? With the exception of human space exploration, do we lose mass too? [link] [comments]  |
| What is the expected black hole merger rate for the Milky Way? Posted: 26 Apr 2018 07:44 AM PDT How long do we have to wait before we'd expect to see a black hole merger from within our own Galaxy? Wouldn't this be like a bjdillion sigma event? What could we potentially learn from it when it happens? [link] [comments]  |
| Does de-heading Yellow dandelions reduce their spread? Posted: 25 Apr 2018 04:26 PM PDT When I was a kid, I would pull the yellow flowers off dandelions on the theory the seeds would not mature and would not be able to take root. Or maybe that they just would not spread widely and would just die there on top of the rest of the grass. I was scolded for this by people who, accurately I'm sure, said I would have to pull it up by the roots of i cared to get rid of it. But - does de-heading the yellow flowers have any effect?

| Why are brake discs made out of steel? Posted: 26 Apr 2018 06:13 AM PDT The title really says it all. I'm wondering that why are cars brake discs made out of steel? Shouldn't it be more clever to make them out of stainless steel? Thanks all to you smart people! [link] [comments]  |
| How do calculators calculate roots? Posted: 25 Apr 2018 04:06 PM PDT Are there formulas for roots and others numbers such as "pi" or "e", or are the values stored in the memory? Also, if there are formulas, how do you make sure it's accurate? [link] [comments]  |

| How do pipes in skyscrapers deal with hydrostatic forces? Posted: 25 Apr 2018 01:49 PM PDT If a pipe with water ran up the skyscraper, eventually the hydrostatic force would overcome the inward force of the pipes (at the bottom), how do engineers deal with the process of moving water up/down that high?

| How does soap remove germs, odors and bacteria from our bodies and hands? Posted: 25 Apr 2018 12:37 PM PDT I mean. Why exactly do we use soap? What does it do that plain water does not do? I know when I google it , it bring up the saponification process and talks about how it removes oils... But how does this correlate with removing germs, odors, and bacteria? Are they trapped within the oils? What would happen if we ditched soaps on our hands, and in the shower.. and shampoo, etc... Have never really knows how exactly soap works and why we use it [link] [comments]  |
| Would dust in a PC slow down performance in any way? Posted: 25 Apr 2018 02:22 PM PDT Almost feels like something for r/NoStupidQuestions, but would cleaning dust out of a PC make it run faster? [link] [comments]  |
| Can you become colorblind after birth? Posted: 25 Apr 2018 11:02 PM PDT Whenever I hear about someone being colorblind it is a condition they've had since birth, but is it possible for someone to become colorblind at another point in life? If so, how? [link] [comments]  |
