We Need to Talk About Kelvin

We Need to Talk About Kelvin

Look around you…

The reflection of your face in a window tells you that the universe at its deepest level is orchestrated by chance.

The iron in a spot of blood on your finger tells you that out in space there must be a furnace at a temperature of 4.5 billion degrees.

The static on a badly tuned TV screen tells you that the universe began in a big bang.

In fact, your very existence tells you this may not be the only universe but merely one among an infinity of others, stacked like the pages of a never-ending book.

With the aid of a falling leaf, or a rose, or a starry night sky, Marcus Chown shows how familiar features of the world reveal profound truths about the ultimate nature of the Universe.

  • Wow, what can you say apart from ‘great title!’ A fantastic piece of popular science writing. Marcus Chown has a real talent for explaining complex scientific ideas to the layperson, and his latest offering employs the premise of using everyday observations of the world around us to explain why deeper scientific truths must indeed be a reality (and also why we take for granted some fairly remarkable things). A great book that makes we want to understand the universe better. Surely there can be no higher praise.


  • The award for the cleverest title of the year goes to the popular science writer Marcus Chown for We Need to Talk About Kelvin. The content also doesn’t disappoint.
