| Why do photons obey the law of equal angles, when reflected off of a mirror? Posted: 09 Aug 2018 06:31 AM PDT It makes sense why macroscopical particles are bounced back in an angle opposite that of their initial trajectory, when they collide with a surface. And in the wavefront-interpretation of light, where the electromagnetic wave induces a small current in the surface of a reflecting medium, causing a new wave to propagate, I can make sense of it as well.. But when viewing light as photons, reflection is, if I recall correctly, a matter of absorbtion and re-emission from a single electron. And this is were logic fails me, for why is the new photon not emitted in a completely random direction? Why is the angle fixed? [link] [comments]  |
| Why are the largest lakes in North America all roughly aligned? Posted: 08 Aug 2018 10:02 AM PDT If you drew a somewhat curved line from The Great Slave Lake to Lake Erie, that line would go through or near 13 of the 15 largest North American lakes. Why is this? Is it a coincidence or is there a geological reason? [link] [comments]  |
| How would we know if Dolphins or some other animal had a language? Posted: 08 Aug 2018 08:57 PM PDT Dolphins have names, elephants and many kinds of birds have specific sounds to inform other of certain circumstances. These are probably not languages, but our own ancestors probably went through similar stages, so, how could we know if some animal species had a full fleshed language?, what would be the evidence to look out for?

| What would the cancelled Superconducting supercollider have achieved? Posted: 08 Aug 2018 11:44 PM PDT In news articles at the time they kept on saying it would lead to more powerful rockets which got my space obsessed childhood self excited, but they never said how, was that nonsense?

| How does turbulence affect velocity of objects in water? Posted: 09 Aug 2018 03:36 AM PDT Does it decrease an object's terminal velocity in water, or could it cause something to actually go faster? [link] [comments]  |

| How does a nail grow off the nail bed? Posted: 08 Aug 2018 08:07 PM PDT What I'm wondering is how the skin detaches from the nail where your nail starts to grow away from your actual finger. I know that the visible nail cells are already dead, so at the boundary between where our nails actually attach to our skin and where it grows away is there a little factory of skin cells working to detach and re-attach themselves to the nail?

| Posted: 08 Aug 2018 05:59 PM PDT According to Google, a proton weighs about 1.6726219 × 10-27 kg. How can scientists measure a single proton to that level of precision (8 significant digits)? [link] [comments]  |
| How would light travel down an isolated, infinite glass fiber? Posted: 08 Aug 2018 08:22 PM PDT Maybe this question showcases my lack of understanding more than anything else, but I'm wondering if there's any intersection between what the double slit experiment shows, and what would happen if you sent a beam of light down an infinite conduit. If a beam of light is so narrowly concentrated that there is only one possible path for it to travel, and it is prevented from ever leaving this path, can it still be described as a wave? Besides problems with infinity, is there a reason this scenario could never happen? Let's say the beam of light was never 'observed', could the light particle ever show up outside of the tube? Thanks! [link] [comments]  |

| How does soap work to get rid of odors and bacteria? Posted: 08 Aug 2018 11:44 PM PDT I know washing with soap helps rinse away some of of your natural oils when washing any part of your body whether it be your hands, face, arm pits , groin , etc...... But everytime I ask how soap makes our hands cleaner from germs or how it makes us smell better.... The answer i get is because.... You are essentially washing away oils because one end of soap molecules love water - they are hydrophilic. The other end of soap molecules hate water - they are hydrophobic. This allows oils and grease to removed.... But how does this correlate to our hands being cleaner from germs and bacteria. And how does it correlate to removing odors from our armpits and body, etc... Are the odors, bacteria germs trapped on these oils? How does soap work to make us cleaner? [link] [comments]  |

| Where electrons go when they "leak" to ground? Posted: 08 Aug 2018 08:17 AM PDT In a electric class my teacher said Earth can drain an infinite amount of electrons or give them to us. But where they go? Or where they come from? Are there different amount of "free" electrons in the different layers of Earth? [link] [comments]  |

| Posted: 09 Aug 2018 02:13 AM PDT I'm not in any way a flat-earther, but I was trying to be devil's advocate yesterday and couldn't come up with anything. If I live by the sea and have good eyesight and I happen to observe a tall ship sailing away from me … it's a bit complicated. [link] [comments]  |
