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:

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
  4. Posts must be original/unique
  5. Adhere to Lemmy's Code of Conduct and the TOS

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.

Applies to many other colors as well. I "understand" why that is but it hurts my brain to think about.

Absolutely. There is no single wavelength of light being produced that would look yellow on its own, but yellow is the word we have for when our long and medium cones both get activated, and a display does produce light that does that. Yellow exists in our brains, so I think it's pretty reasonable to say that either yellow exists somewhere in this process or no colors do.

Well, there is a wavelength that by itself activates both of these cones such that we interpret it as yellow. But a combination of wavelengths also does that
