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.

I've been studying a bit of human history recently and as many of you have probably heard, the worldwide population count increased sharply in the last century or so. link

the world's population was between 250 million and 500 million throughout the entire medieval age (500 AD to 1500 AD), so i assumed 330 million people on average (which it was around 1000 AD). 330 million people for a thousand years makes 330 billion human-years.

In the time period since 1970, approximately 6 billion people lived on earth on average, so that makes 55 * 6 billion = 330 billion human-years.

so, roughly speaking, as many human-years happened since 1970 than in the entire medieval history.

that might do a part in explaining why technological and societal progress has been so fast in the last couple of decades.
