Schwartz inequality in bra-ket notation

Schwartz inequality in bra-ket notation

Motivation

In [2] the Schwartz inequality

\begin{equation}\label{eqn:qmSchwartz:20} \boxed{ \braket{a}{a} \braket{b}{b} \ge \Abs{\braket{a}{b}}^2, } \end{equation}

is used in the derivation of the uncertainty relation. The proof of the Schwartz inequality uses a sneaky substitution that doesn’t seem obvious, and is even less…

Animation Update 3rd Nov- 

Today I worked with Franki later than usual, as her schedule is becoming more and more hectic as she draws towards hand-in. She is unsure whether or not she can still be my projection operator, as her workload is very heavy at the moment. Whilst I would love to have Franki as my operator, her decision comes first and I have assured her that if he needs to, Bradley can become an operator to take her place. I have asked her to give me a definite answer on Friday, so that I can plan ahead and train Bradley if it comes to it. 

Today, we made lightning strikes for the storm scene. We tried to create bolts of lightning of Photoshop and Maya, but found they looked too flat and unrealistic. I suggested we try After Effects, as I saw Kavi using some of the presets on that program to make some of the projections for The Women.

We found a preset we really liked, but didn't know how to control it as an animation. So, our solution has been to screenshot the After Effects render window, and put that image onto Photoshop to animate. I really like the Photoshop animation features, as it is very simple and easy to tween between frames. 

We have made several bolts of lightning videos in pairs, so I can cue them as and when they are needed.
