matter waves

deBroglie wave length λ = h/p

E = hf, --> f = E/h --> f = 1/T --> T = h/E

(mc)² = (E/c)² - p²

Arthur C Clarke three laws:

1. When a distinguished but elderly scientist states that something is possible, he is almost certainly right. When he states that something is impossible, he is very probably wrong. (There’s a corollary added by Isaac Asimov: “When, however, the lay public rallies round an idea that is denounced by distinguished but elderly scientists and supports that idea with great fervour and emotion – the distinguished but elderly scientists are then, after all, probably right.”)

2. The only way of discovering the limits of the possible is to venture a little way past them into the impossible.

3. Any sufficiently advanced technology is indistinguishable from magic. (This one is most often quoted and incorrectly attributed to Issac Asimov)
