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.

*the speed of light squared

It's not incorrect, it's just the way engineers do equations.

e = mc

π = 3

g = 10 m/s²

Well, what is then the last symbol doing in the last line?

Spoken like someone who's never met an engineer

So close

In natural units, where c = ħ =1, both statements are equally true. But then, the whole premise is lost because in these units, E = m (for stationary bodies).

And m represents mass, not matter. Matter has mass, but that doesn't mean it is mass.

Where have you seen square light? Duh!

That's not a face I expected to see today.

But if you multiply by 2, then you matter twice as much?

[–] chimasterflex 3 points 1 year ago

you sure do bro

[–] [email protected] 2 points 1 year ago* (last edited 1 year ago)

Why multiply? Light doesn't do that.

All light matter … and also energy
