h with a line through it?
So Dr. Lavelle was talking about how h/4pi is the same as h with that line through it/2pi, can someone explain the difference?

Re: h with a line through it?
As the person stated above, h-bar is the same thing as h/2, there is no difference.
Re: h with a line through it?
h bar is h/2π. The difference is in the Heisenberg equation where it could be (Δp x Δx) = h/4π or (Δp x Δx) = 1/2(h bar). 1/2(h bar) simplifies to h/4π

It just represents another one of those symbols that physicists created to make their lives easier while writing calculations. Its a similar concept to the Hamiltonian, which represents a long expression related to wave-particle duality with the letter H.

H bar is just a short hand notation, that is used just to simplify what is written. ( Hbar= h/2 pi) (H bar/2 = h/4 pi)

Re: h with a line through it?
h bar is essentially another way to say h/2pi. it can also be called Planck's constant, in case you didn't already know (I just discovered this in my discussion section)

Re: h with a line through it?
h bar is equivalent to h/2pi so...hbar/2 is equivalent to h over 4pi which is what the right side of the Heisenberg equation requires.
