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

All posts must be showerthoughts
The entire showerthought must be in the title
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.

The original idea behind imperial units is actually quite nice. They used 12 inches in a foot because you could divide it in so many ways without using decimals. You can take 1/2 of it, 1/3, 1/4, and 1/6 without ever needing decimals.

You can measure 1/2, 1/3, or 1/4 of a meter, why wouldn’t you? Also, seriously, those common fractions aren’t that hard in decimal. Everybody knows that 125 g is 1/8 kg.

That’s not the issue. The issue is that it’s not consistent between imperial units, you have a zoo of different subdivisions between units. You have 12 inches in a foot, three foot in a yard etc pp.

The issue is it gets really unwieldy in multiplication, 1 cubic ft is how many cubic inches… 1728, how convenient.

Tell me how much is 1/6 cubic ft in inches? How many cups are that? There goes your mental math.

(It is also a common misconception that imperial is „duodecimal“. It’s not. It’s counting to 12 in decimal. If you had a proper duodecimal system, „12“ * „12“ would make 100 not 144.)

We all still use 360° in a circle

And you also say 180°, 45°, 720°. Not 1/2, 1/8, 2.
