Newton still thought of light as “fiery particles” – an unfortunate analogy, considering that his first manuscript caught fire when he ...

If you want to repeat one of Isaac Newton’s most significant experiments, try holding your index and middle fingers up to the light (don’t do this, as I once did, in a train full of drunken football supporters!). With the tips of the fingers just touching, there will be a small gap lower down through which the light can pass. Look carefully at the middle of the gap. If your fingers are close enough, there will be a black line down it. Where ...

In fact, he’d probably seen them as a child, reflected from the bubbles in his bath, and of course in the colours of the rainbow, which appear when white light is split up by being bounced around inside raindrops. Newton was the first, however, to think of using a ...
