He previously won in 2004 with A Short History Of Nearly Everything.

A shortlist was selected from more than 172 submissions published between July 1 2019 and September 30 2020.

Biologist and poet Professor Anne Osbourn, chairwoman of this year’s judging panel, said the books “represent carefully crafted explorations of the worlds both around and within us”.

She added: “These books make science intriguing, accessible and exciting.

“Some raise awareness of the scientific process, and of our understanding that scientists are humans too.

“Others are a call to arms, asking us to consider our place in the universe and what we can bring to humanity in our various ways.

“There is darkness, revelation and hope. There is inspiration.”

Alongside Prof Osbourn, the 2020 judging panel features Blackwell’s trade buying manager Katharine Fry, journalist Katy Guest, Royal Society university research fellow Dr Kartic Subr, and actress and author Sophie Ward.

The winner will be announced in a virtual awards ceremony on November 3.
