Have a very cool video that Alom Shaha pointed out to me, without even mentioning that he’s the one wot wrote it. It’s narrated by Jim Al-Khalili. It’s about the difference between “just a theory” (as in a “theory” that Elvis is still alive or a “theory” that the reason your friend believes that is because she has low self-esteem) and a scientific theory.
It’s got brilliant animations.
