A Bee in a Cathedral by Joel Levy is a fascinating book of science analogies and astonishing numbers. Suitable for all ages, only the physics section is a bit complex. A few of my favourites factoids:
- Every day 1 million meteoroids strike the Earth
- How far to the nearest star, Proxima Centauri? Travelling in a rocket at 250,000km/h, it would take you 18,000 years
- Most of the living cells in your body are less than a month old
- About 50 million neutrinos are passing through you now
- Every molecule in a glass of water is changing partners billions of times a second.
- How hard does your heart pump blood? Empty a bathtub in 15 minutes using only a teacup —repeat this without stopping for the rest of your life
- If an atom were blown up to the size of a cathedral, the nucleus would be no larger than a bee buzzing about in the centre.
