What does it mean? Could someone explain the last equation?

The relationship between frequency and angular frequency: ω=2πf with f=1/T

Ah! Weird notation misled me. That's obvious!

The joke is simply that these relationships are written in a non standard form, making it look "weird".

F = a m , usually written as F = m a,
Newton's second law of motion, equating the force acting on an object with the mass experiencing an acceleration.

c2 m = E, usually written as E = m c2
The mass - energy equivalence. All mass that exists and is at rest (stationary) still contains an Intrinsic energy.

T-1 π2, usually written as 2π T-1 = ω or 2πf = ω

T is the time period, the time it takes for a repeating process to repeat once. f is frequency, how many times per time interval (usually per second) something will occur.

Cyclical patterns can be represented as a pointer rotating around a circle. That pointer can be represented as the angle it makes with the x axis. The angular frequency is the angle per unit time or rate of change of that angles (how fast the angle changes).

Yeah, that's some basic stuff, I guess I got confused too much to get it
