| Posted: 24 Nov 2016 01:53 AM PST The Sun has a surface temperature of about 6,000 kelvins, and to my knowledge, two things are happening when fire is blue:

| Mathematically speaking, is there anything special about three spatial dimensions? Posted: 24 Nov 2016 12:10 AM PST Are there any quirky symmetries or other mathematical properties that are unique to R3, beyond the readily perceptible? [link] [comments]  |

| Why is the James Webb Space Telescope being launched from French Guiana? Posted: 23 Nov 2016 03:47 PM PST Why is it advantageous to be closer to the equator for launch? [link] [comments]  |

| Posted: 23 Nov 2016 10:55 AM PST To be more specific, scientists know that fusion exists and are trying to develop technology to harness its vast amounts of power. Is there a similar "holy grail" with battery tech that engineers and scientists are working towards that would revolutionize energy storage? [link] [comments]  |
| Can electric propulsion be used to launch rockets into space? Posted: 24 Nov 2016 04:12 AM PST I've been looking at the differences between chemical engines and electric propulsion (EP) engines for rockets. Whilst the EP engines work well in space they don't seem to have enough thrust to launch a rocket into space and completely replace chemical engines. Does anyone know if this has been done or could possibly be done with the technology we have now? [link] [comments]  |
| Does electromagnetic shield block all forms of radio waves? Posted: 23 Nov 2016 01:02 PM PST For example if I was in a room that was RF shielded, does that mean that a ham radio, CB radio, my cellphone, a 5 year old cellphone, wifi, data, location services, my GPS would all stop working? Or does it only prevent one band? [link] [comments]  |
| Why is Iron more stable than Nickel even though it has a lower binding energy per nucleon? Posted: 23 Nov 2016 11:48 AM PST Im studying nuclear physics in school and we were looking at the binding energy per nucleon graph. The element becomes more stable as the binding energy per nucleon increases. So from the graph you can see that smaller elements carry out fusion, and larger elements fission, in order to become more stable. We were told that iron is the most stable element, however nickel has a higher binding energy per nucleon. Why is Iron more stable? [link] [comments]  |
| What happens in the rest frame of a particle that is causing Cherenkov radiation? Posted: 23 Nov 2016 11:01 AM PST I understand that Cherenkov radiation is what happens when a charged particle in a medium exceeds the local speed of light (not c). What does this look like in that particle's rest frame? Are the photons travelling backwards? [link] [comments]  |

| Are there any naturally-occurring large-scale organic materials that don't decompose? Posted: 23 Nov 2016 05:33 PM PST I know that in the Carboniferous, the ability to digest lignin hadn't been evolved yet, and that contributed to the vast coal beds laid down at the time. Are there any such organic digestive dead-ends in contemporary times? I know that many plastics are indigestible, but they're man-made. Crude oil is by-and-large indigestible (I believe some specialized bacteria can actually digest it). Thanks in advance! [link] [comments]  |

| Are people born with different pain tolerance levels, or is that a learned thing? Posted: 23 Nov 2016 01:29 PM PST Do all babies experience pain at the same levels, and over time, some people have experiences (whether sought after or not) that increase pain tolerance? Or are some babies born with higher tolerances for pain and that continues through their life? [link] [comments]  |
| Posted: 23 Nov 2016 11:48 AM PST Basically, I'm wondering if a monitor displaying bright, white colors most of the time will consume more energy than one displaying mostly dark colors. Assuming all else being equal, of course. [link] [comments]  |

| Is a sour taste the opposite of sweet one? Posted: 23 Nov 2016 04:12 PM PST Is sour just the absence of sweet or are they completely different? [link] [comments]  |
