| How can a vessel contain 100M degrees celsius? Posted: 26 Dec 2020 07:43 AM PST This is within context of the KSTAR project, but I'm curious how a material can contain that much heat. 100,000,000°c seems like an ABSURD amount of heat to contain. Is it strictly a feat of material science, or is there more at play? (chemical shielding, etc) https://phys.org/news/2020-12-korean-artificial-sun-world-sec-long.html [link] [comments]  |
| Christmas question: 'A bad lobster in a dark cellar' - what does it mean??? Posted: 25 Dec 2020 09:35 AM PST I am rereading Dickens' A Christmas Carol. There is a line that says, 'It was not in impenetrable shadow as the other objects in the yard were, but had a dismal light about it, like a bad lobster in a dark cellar.' What does this mean? Do lobsters have bioluminescence when they start to go bad? Would they glow for some other reason? Do they glow at all? Can anyone shed any light on this? Thank you! [link] [comments]  |

| Posted: 26 Dec 2020 07:18 AM PST Can only organisms and viruses produce complex molecular structures and polymers in nature, or are there other systems that contain a large amount of repeating complex patterns? [link] [comments]  |

| Are the emotions induced by music universal among different cultures or are they something learned? Posted: 26 Dec 2020 08:25 AM PST There seems to be a lot of consensus about what music is sad, happy scary etc. but is this something created by culture or is it something more primitive and in common for all people? If it is not learned but imbedded within our brain, what would be the explanation for it, since it doesn't seem it is present in nature in any way. [link] [comments]  |
| Do all elements have unique light signatures when light is reflected off their surface? Posted: 26 Dec 2020 07:22 AM PST Do all elements have unique light signatures when light is reflected from their surface? If so, could lasers be used to identify metal during plane crash searches and also identify precious metals during geological surveys? [link] [comments]  |
| What makes depleted uranium beneficial as a projectile? Posted: 25 Dec 2020 11:10 AM PST Is there some effect that depleted uranium bullets / shells have? I understand the 'depleted' part just means it's not radioactive (right?) but why is it specifically used. I seem to have read some things about it carrying more energy because of its density, but to get that energy out, wouldn't you have to put more energy in to fire it in the first place?

| Posted: 25 Dec 2020 07:57 PM PST The "killed vaccine" seems most commonplace in the world, and with the recent developments and deployments of mRNA vaccines, I've begun to wonder what else is out there (and perhaps what else is possible). Can anyone help with this? [link] [comments]  |
| Does the climate of an area affect or determine what type of metals are commonly found there? Posted: 25 Dec 2020 02:56 PM PST I tried searching myself online, but was having trouble find anything useful. I may have just been using the wrong keywords. [link] [comments]  |

| Posted: 25 Dec 2020 04:14 AM PST My country has just stated that a vaccine is being worked on and should be available for public use in mid-late 2021. However some countries like USA already have vaccines authorized for public use. Why would we still need to work on making one when we can just use the one that has already been tested and proven to be effective? [link] [comments]  |
| What is it that prevents scientists from developing an HIV vaccine? Posted: 24 Dec 2020 08:53 PM PST A COVID vaccine was developed in less than a year. Why hasn't an HIV vaccine been developed yet? [link] [comments]  |
