| Why do humans often mess up on simple counting? Posted: 02 Aug 2018 01:53 AM PDT It seems odd that in many stressful and non-stressful environments humans often lose count of something so basic; say they're counting coins they may have to start over again a couple of times because they keep losing count. It's mainly weird to me, because it's so simple. [link] [comments]  |
| What is the effect of radiation on lead? Posted: 02 Aug 2018 05:03 AM PDT I heard about radithor today, basically a drink from the 20's that was meant to heal all your ills. It contained radium 226 and radium 228. A person died from ingesting too much. They were buried in a lead lined coffin. Exhumed in the 50s, he was still radioactive and presumably replaced in the lead lined coffin. My question is, what will happen to the inside of the coffin and specifically to the lead. Will the particles be dissipated into the lead as heat. Will the lead disappear slowly to nothing? [link] [comments]  |
| How does zooming in on an image work? Posted: 02 Aug 2018 04:29 AM PDT If on a 1920x1080 screen you look at a 1080p image on full screen, one pixel of the image would theoretically use 1 pixel on the display. But if I then zoom in that ratio would be ruined unless it's 4x magnification when 1 image pixel takes up a 2x2 square of LEDs on the screen. How would any magnification in-between 1x and 4x be displayed? Or have I got the wrong idea on how it works? [link] [comments]  |
| Why does putting scalding water on a rash feel good? Posted: 02 Aug 2018 08:16 AM PDT I've found that cranking up the temp in a shower to the point my healthy skin feels pain but something like a poison ivy rash under the same water is euphoric, what is going on? [link] [comments]  |

| Posted: 02 Aug 2018 06:48 AM PDT Alternatively, is it possible for a changing magnetic field from an electromagnet to produce visible light as radiation instead of invisible magnetic field line? Does this have something to do with frequency? [link] [comments]  |

| What makes a cancer spread to a specific place in the body? Posted: 01 Aug 2018 05:43 PM PDT For example, I've heard small-cell lung cancer likes to metastasize to the brain first. But why to the brain? Wouldn't it have the same probability of spreading to any of your organs/bones? Is there a biological basis to this, or is it more based off statistics of people who suffer from small-cell lung cancer? [link] [comments]  |

| In Thermal Expansion, how does the material know which direction it would be expanded? Posted: 01 Aug 2018 10:56 PM PDT For example, a metal sheet with a hole. Instead of the material expands through the space provided by the hole, it expands away from the whole surface of the material, which makes the hole larger. [link] [comments]  |

| Does a magnetic field induce current in a different way depending on the charge of the particles? Posted: 01 Aug 2018 12:15 PM PDT I've been learning about fusion reactors and magnetic confinement, and read that magnetic coils can be used to induce a current in ("neutrally-charged") plasma, and I wondered why that was.
In physics, you learn that a magnetic field will induce an electric current in a wire. However, we've almost been "tricked" into thinking that this only applies to negatively-charged electrons.
Do magnetic fields affect positively-charged particles in the same way as they do electrons in a wire? Do they move in the opposite direction? How about with neutral particles? Does the charge not actually matter and current is just a fancy way to say "something's moving"? [link] [comments]  |
| Are there any uses for polygons with large numbers of sides? Posted: 01 Aug 2018 06:00 PM PDT I was discussing this with my SO today. Are there any uses for things like a Myriagon with 10,000 sides? I understand the practical uses of common polygons but why would you ever use something with a million sides? [link] [comments]  |
