Not sure which is harder: Quantum Mechanics or Vietnamese.. :D
Both and neither ;)
Quantum mechanics on Vietnamese
Haha ... You are funny.
I am learning Quantum Mechanics. It's very difficult and have many complex formulas. It's not easy to understand.
It is counter intuitive
Why is it teaching about but can't just be teaching?
It is accepted now :)
the "about" is redundant- as that is what teaching implies
accepts "..teaching quantum mechanics".
