Comment on Let π = 5
maniclucky@lemmy.world 8 months agoExcuse me what? I’ve been an engineer for a decade and have never met anyone that would do that. We have calculators.

I think they mean napkin math. Like you’re in a meeting and they ask for a general idea if something will work or not

We all have phones with calculators, don’t really need to do napkin math anymore

Depends on the level of precision you need. If I want the volume in a 500 foot long, 3 inch pipe to roughly estimate how much supply I need to order, I wouldn’t need a calculator. It would very roughly be 90-95 ft3. (Divide 500 by 4 two times and multiple by 3)
Then I would spend 5 minutes double checking myself haha.

I suppose. I’m still internally outraged and haven’t run into such a situation before, but I accept this.
assassin_aragorn@lemmy.world 7 months ago
To be fair most of the situations where I’ve run into this have never involved pi, and sometimes it’s just qualitative.
maniclucky@lemmy.world 7 months ago
That makes sense. I feel like if you’re at the point where pi is meaningfully involved, you should probably do your math.
