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.

2+2 = 5

…for sufficiently large values of 2

i was in a math class once where a physics major treated a particular variable as one because at csmic scale the value of the variable basically doesn't matter. the math professor both was and wasn't amused

I mean as an engineer, this should actually be 2+2=4 +/-1.

Statistician: 1+1=sqrt(2)

Computer science: 2+2=4 (for integers at least; try this with floating point numbers at your own peril, you absolute fool)

Freshmen engineer: wow floating point numbers are great.

Senior engineer: actually the distribution of floating point errors is mindfuck.

Professional engineer: the mean error for all pairwaise 64 bit floating point operations is smaller than the Planck constant.

0.1 + 0.2 = 0.30000000000000004

units don't match, though
