Professor Hawking’s memorial stone in Westminster Abbey. Made from Caithness slate stone and designed and made by John Maine, with letter cutting by Gillian Forbes. The inscription is an English translation of a phrase that appears in Latin on Newton's gravestone:

Here Lies What Was Mortal Of Stephen Hawking 1942-2018

The stone depicts a series of rings, surrounding a darker central ellipse. The ten characters of Hawking's equation express his idea that black holes in the universe are not entirely black but emit a glow – this is now known as 'Hawking radiation'.

The stone lies alongside those of Sir Isaac Newton and Charles Darwin.
