Despite the controversy, evolution was widely accepted by many naturalists within a few years of the Origin’s appearance. An important reason for this rapid triumph was Darwin’s botanical works. Seen through evolutionary eyes, plants proved to be mobile, carnivorous, sensitive – even crafty.
Scriabin was Rachmaninov’s classmate at the Moscow Conservatoire, and enjoyed comparable fame during his lifetime, and yet today he is much less known, especially outside Russia.
This lecture will look at change ringing, which is ringing a series of tuned bells (as you might find in the bell tower of a church) in a particular sequence, and this has exciting mathematical properties. We will also ask: why are bells bell-shaped?
Boris Ord composed one tiny Christmas carol – ‘Adam lay ybounden’. But Ord’s largest contribution to the carol genre was his work as choirmaster at King’s College, Cambridge from 1929 to 1957.

The story of the deep, biogeophysical planetary connections and how these are intensifying the effects of climate change and economic development, is told through personal research and expeditions to remote locations across the world (including some that were previously unexplored).
