A "Showerthought" is a simple term used to describe the thoughts that pop into your head while you're doing everyday things like taking a shower, driving, or just daydreaming. The most popular seem to be lighthearted clever little truths, hidden in daily life.
Here are some examples to inspire your own showerthoughts:
If you made it this far, showerthoughts is accepting new mods. This community is generally tame so its not a lot of work, but having a few more mods would help reports get addressed a little sooner.
Whats it like to be a mod? Reports just show up as messages in your Lemmy inbox, and if a different mod has already addressed the report, the message goes away and you never worry about it.

Think how different your life would be without all the people who invented and improved upon computers
Yeah, it was Fred. We should thank him more often.
Thanks Fred!
The amazing thing is, there are so many ways the metals could have ended up in the coins. For example, iron is pretty simple, you just heat up the rocks and molten iron begins to leak out. Aluminium is really weird, because finding it in a metallic form is very rare. However, there are aluminium containing minerals pretty much everywhere. Turns out, you can dissolve those rocks with some chemicals, and separate the aluminium from all the other junk with electricity.
Alumina (aluminum oxide) is what you are extracting from aluminum ore and it's tough as fuck, which is why it's easier to dissolve the rest of the stuff around it first.
Oxygen is mainly that other "junk" you have to separate with electricity. While the smelters only run at 4.5 volts (per cell), they have to push about 300kA to get the stuff up to ~950°C which breaks its chemical bond.
You probably have never even touched pure aluminum before. Aluminum and oxygen react so quick, all we typically ever see and touch is a alumina shell.
