Welcome to c/science_memes @ Mander.xyz!

A place for majestic STEMLORD peacocking, as well as memes about the realities of working in a lab.

Rules

  1. Don't throw mud. Behave like an intellectual and remember the human.
  2. Keep it rooted (on topic).
  3. No spam.
  4. Infographics welcome, get schooled.

This is a science community. We use the Dawkins definition of meme.

\cdot for matrix multiplication and the dot product, \times for cross product and nothing (or *, if I want to write it explicitly and have no convolution in the expression) for regular multiplication.

But why

[–] thatsTheCatch@lemmy.nz 5 points 5 months ago* (last edited 5 months ago)

'*' is commonly used for multiplication in computer programming, so it's probably that. Also in your calculator app

** for power?

[–] the_beber@lemm.ee 1 points 5 months ago

^ for power. ** is usually in a programming setting (but it‘s usually a method and not an operator there.)
