Review: What A Wonderful World, By Marcus Chown

Reading a well-written popular science book is one of the great pleasures of modern times, and this guided tour through life, the universe, and everything affords that pleasure in abundance. Marcus Chown takes us by the hand and leads us through the labyrinthine mysteries of the origins of life, evolution, the cells of the body, the brain-boggling brain, electricity (I’ve never understood what that stuff is; I still don’t, but my ignorance is now better-defined), the crazy truths of quantum theory, gravity, time, stars, and black holes. You can get drunk on the sheer strangeness of the theories – for instance, you have an infinite number of doppelgangers, and the nearest one is 10^10^28 metres away. And we may all be holograms.

Book of a lifetime: Cyclopaedia, By Ephraim Chambers

As a historian of 18th-century London, it would be too predictable to choose Samuel Johnson's great Dictionary of 1775 as my choice for a book with enduring impact.

The paper raises the question of whether alien races could have used the gravity of stars to “slingshot” probes in order to gain speed: a technique humans already use for probes, such as the Voyager.

Self-replicating alien space probes could already be in our solar system, say mathematicians

Mathematicians analysed the possibility that probes could travel through space in a study published in the Journal of Astrobiology

Tom Lehrer's spring isn't complete without poisoning them in the park; Dick Dastardly dratted and double-dratted himself to near-oblivion chasing one. For the rest of us, it's become all too easy to vilify them as "rats with wings".
