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. A showerthought should offer a unique perspective on an ordinary part of life.
Rules
- All posts must be showerthoughts
- The entire showerthought must be in the title
- Avoid politics
- 3.1) NEW RULE as of 5 Nov 2024, trying it out
- 3.2) Political posts often end up being circle jerks (not offering unique perspective) or enflaming (too much work for mods).
- 3.3) Try c/politicaldiscussion, volunteer as a mod here, or start your own community.
- Posts must be original/unique
- Adhere to Lemmy's Code of Conduct

In normal everyday life, you rarely need to involve time in your calculations. In science and engineering you do, and that’s when you run into problems.
When comparing two pumps, you run into issues like this. Which one is bigger: 29 m^3/h or 410 l/min. Doing calculations like that once or twice is recreational mathematics, but in a professional setting, these conversions are speed bumps standing in the way of getting stuff done.
Don't they have conversation lookup tables for stuff like that? Been years since I was in school so maybe those aren't really used anymore? At least to convert the numerator to different units.
They do, his take is nonsense and sounds like RP, don't take it too seriously. Any trained engineer can tell you the historical reasons why we use base 60 for circles. This is actually a well known computer science issue, but not an engineering or math one.
Pump manufacturers are like: “We’re selling this professional grade stuff to people who know what they’re doing. They know how to math their way through this mess.”
