purge comments on Uncalibrated quantum experiments act clasically

If α is smaller it’s less than half-silvered, and if α is bigger it’s more than half-silvered.

Just a nit, but isn’t this backwards? Less silvering means less reflection and more transmission, but this first diagram labels the transmitted amplitude as α, not the reflected amplitude.

Thanks. It was the diagram that was backwards; I meant for $\alpha$ to be the amplitude of reflection, not of transmission. I updated the diagram.
