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: 1

Rules

  1. All posts must be showerthoughts
  2. The entire showerthought must be in the title
  3. No politics
    • If your topic is in a grey area, please phrase it to emphasize the fascinating aspects, not the dramatic aspects. You can do this by avoiding overly politicized terms such as "capitalism" and "communism". If you must make comparisons, you can say something is different without saying something is better/worse.
    • A good place for politics is c/politicaldiscussion
    • If you feel strongly that you want politics back, please volunteer as a mod.
  4. Posts must be original/unique
  5. Adhere to Lemmy's Code of Conduct

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.

I'll tell you something I do as a woodworker a lot that metric isn't great for: divide by powers of two, three or four. I've got some boards milled up 3/4" thick. I'm going to join them with a bridle joint, that means cutting the middle third out of one and the outer two thirds from the other. So each of the remaining "tongues" are each 1/4" thick. 3/4" is approximately 20mm. That's a nice metric number, a multiple of 10. Let's cut that same bridle joint in 20mm stock. What's a third of 20mm? Can you come point to 6.6666mm on my metric tape measure here?

Don't pretend base ten doesn't do stupid things too.

Can you come point to 6.6666mm on my metric tape measure here?

Yes: For woodworkers, it's identical to 6.5mm, accurately eyeballed at between 6 and 5mm. Don't pretend you're a machinist. Does your tape measure even have a vernier scale. Does it make satisfying clicks when measuring. If you have a slip instead of interference fit just dump one piece in water for a second it'll be fine.

To be more precise, it should be rounded as 6.7 cm, accurately eyeballed at between 6.6 cm and 6.7 cm.
