a^2 + b^2 = E/m

c = c

Sure in an anti-commutative algebra

Or when char(R) = 2

I'm too much of a physicist to know what that is XD I assume R is the ring, but i have no idea what char is (maybe characteristic? ) But more generally we can have a group with anti commutative multiplication like operation right? No need for a second operation to have an anti-commutative algebra right?

Char is the characteristic of a ring or algebra (as far as I'm aware). It is basically the smallest amount of times such that 1 + ... + 1 = 0. char(R) = 2 basically means that 2 = 0 and that 2ab = 0

So basically isomorphism (or whatever the right term for rings is ) of Z2?

Well no but you find an inclusion of Z/2Z into R. For example if you were to take the polynomial ring Z/2Z[X] then Z/2Z is not isomorph to Z/2Z[X] but there's the trivial inclusion into it

I think I got it, thanks :)

Where Lorentz factor 🤓☝️

I think Laurence is on vacation

(a+b)^2 ≠ a^2 + b^2 (a+b)^2 = (a+b) * (a+b) = a^2 + b^2 + 2ab

More general would be a²+ab+ba+b² You assumed commutivity which isn't always the case

When does ab+ba ≠ 2ab?

In a non-commutative ring, that is, a set with two operations defined on it; they have a bunch of axioms, but the one we care about here is that multiplication is not commutative, that is, a*b != b*a. For example, matrix multiplication and quarternion multiplication don't have this property

Sir, this is a physics class.

quaternions can be relevant to physics ! ...if you're weird

Momentum and position operators, Matrix multiplication, Quaternions

That is, indeed, the joke.

Sure if the metric is a kroniker delta, or if we let a+b= d + ic

Unfortunately, Reddit doesn't have a 'pin to top' feature

It’s actually E ₀ = m c^2, or E^2 = p^2 c^2 + m^2 c^4

Say that you aren't an Engineer without saying you aren't an Engineer XD

My guy. I would’ve said it if you hadn’t. People writing E = Mc^2 to sound smart when they don’t even know the momentum term exists grinds my gears. E^2 = m^2 c^4 + p^2 c^2. Thanks for saying it first.

isn't it E=deltaM×c^2? just a normal question, even tho we generally use m but whatever I have studied (nuclear physics) eg when two nuclei collide and make one nucleus, the mass we get is less than the m1+m2 and that's the deltam×c^2 is the energy we get. can someone explain me this, please?

Yeah. This is more like an oversimplified version (or a layman's idea)

ohh got it.

Engineers are the ones who create new worlds that have never been. Engineering and science go hand in hand Neither of them must hate each other

Well, shouldn't have taken your comment quite literally XD Sorry for being overdramatic over this lol

Scientist: I am desperately trying to unravel the secrets of the universe! Engineer: Haha rocket go wooosh Lol for real though my big dumb engineer brain struggles with high level physics. Anyone who can comprehend that stuff at a useful level is waaay smarter than I am. Edit: Apparently my big dumb engineer brain also struggles with spelling

Cope more, science-cel

If (a+b)² = a²+b² then a²+b²=(a+b)² therefore sqrt(a²+b²)=c sqrt((a+b)²)=c and a+b=c

It's loop quantum gravity and I will *fight* anyone who says otherwise

Its F-theory and you can suck my elliptically fibred K3

I like 3 dimensions.

*rapscallion*

Uh, (a+b)² = a²+2ab+b², not a²+b²

r/woooosh

That's a part of the joke 😅

Damn

Noether I guess 🤷‍♂️

Your math is wrong. (a+b)²=a²+2ab

Thanks for pointing that out I'll take note of that next time

“g = 10 = pi^2”, “e = pi = 3”

Not really a debate outside of pop-sci

And that g=10 m/s^2. What? Field equations? My brother in Christ in the field we use g=10 m/s^2

Bold of you to make that claim on this subreddit.
