I got banned from a… what are we calling them… sublemmy?.. on here for being ‘aggressively negative’. I voiced my disapproval of a character that I didn’t like in a TV show, which included one F-bomb. Some people on here are way too sensitive.
I just posted an article explaining the study to the ‘You Should Know’ community, so hopefully some of the people who need to see it do so
There have been studies which found playing tetris for an hour or two after seeing something traumatic can prevent it taking root in our longterm memory.
I tried it once after accidentally clicking a link on reddit that turned out to be gore, I can’t remember exactly what it was now (about 9 months later) so it must have worked
Nothing. The rewards are special flairs and digital trophies. This is what reddit thinks of their mods.
but all they do is make things warmer with their stupid bouncing
Stupid bouncing people! Thanks for expanding on my comment. I hope they explain this potential discovery for those who don’t understand it.
Some great answers, but none of them ELI5, so I’ll have a go.
When electricity passes through a non-metal, it’s like trying to push a person through a wall, the person just bounces off. When electricity passes through a metal, it’s like you put lots and lots of doors in the wall, so the people (electricity) can pass through it easily. Different metals have different conductivity (more or less doors).
Superconductivity is like taking the wall away completely, 100% of the people can freely pass the threshold. But, so far, we’ve only been able to make superconductors that work at very, very, very low temperatures; or very, very, very high pressures. Of course, it’s not viable for our computer or electric cables to be cooled that much, or pressured that much.
In our modern world, with so many devices running on electricity, we lose lots and lots of energy & money to resistance (those pesky walls with not enough doors). If we had a superconductive material that works at room temperature, and normal pressure, it would mean we can send electricity around the world with very small amounts lost to resistance; it would mean our devices would become incredibly efficient; and likely lead to the development of incredible new technology.
Thanks for the info.
