Atoms, quanta and nuclei — where everyday intuition finally runs out.

Why atoms only emit specific colours of light — never a rainbow.
Random events, predictable outcomes — and how we date ancient bones.
Why bright red light ejects no electrons — but dim blue does.
Every moving particle has a wavelength — even you, but far too small to notice.
One electron at a time, arriving as single dots that pile up into interference.
The more precisely you know where a particle is, the less you can know its speed.
Splitting atoms powers reactors; fusing them powers stars.
