Like.
In the 80s teachers told us we must learn written calculations by hand, because we might not always have a calculator available, which... -
PPhDeezNutz reacted to martinbn's post in the thread B How does the Riemann Hypothesis/Riemann Zeta function even work? with Like.
You may have to accept that not evey topic in mathematics can be explained at a hight school level.

PPhDeezNutz reacted to kuruman's post in the thread Calculating ##\langle zHz \rangle## in different ways with Like.
Actually it's a double reference. Doing it "zee kveek vay" appears in Griffiths' QM book who attributes it to Peter Lorre in Arsenic and...

PPhDeezNutz reacted to vanhees71's post in the thread Classical Which classical mechanics book has better content? with Like.
The reason that in Newtonian mechanics ##T^*=T## is of course that the kinetic energy is a quadradic form of the (generalized)...

PPhDeezNutz reacted to kuruman's post in the thread Slight Confusion in Introductory Mechanics (Dynamics Problem) with Like.
As you do more physics, you will eventually come to the realisation that mechanical energy conservation is a good place to start when...

PPhDeezNutz reacted to Lunar Manatee's post in the thread Slight Confusion in Introductory Mechanics (Dynamics Problem) with Like.
I am familiar with linear non-homogenous differential equations, just didn't really have the wherewithal to confirm it that way; but I...
