*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

Spoken like someone who's never met an engineer

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

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.

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

Where have you seen square light? Duh!

[-] MxM111@kbin.social 7 points 1 year ago

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

[-] chimasterflex@lemmy.world 3 points 1 year ago

you sure do bro

[-] CyberTailor@beehaw.org 3 points 1 year ago

This is so wrong

[-] MonkderZweite@feddit.ch 2 points 1 year ago* (last edited 1 year ago)

Why multiply? Light doesn't do that.

[-] ApeNo1@lemm.ee 2 points 1 year ago

All light matter … and also energy
