Ever been to Gresham College? If not, why not? The itinerant college, over 400 years old, offers free public talks several times a week, on every subject from maths to gods. What's more, they're timed for fitting into your lunch hour, or just after work.
After a summer break, the new season of talks is about to begin. As a taster, here's the lineup for September, but there's a long list of further talks from October through into next spring. Be sure to take a look at the full programme.
17 September: Butterflies, Chaos and Fractals. Raymond Flood looks at chaos theory, at Museum of London. (1pm)
17 September: Britain and the Continent. Vernon Bogdanor, also at Museum of London, on how Britain adjusted after WWII to shape itself up for European union. (6pm)
18 September: How Does Globalisation Affect Inequality Globally? Douglas McWilliams talks economics at Museum of London. (6pm)
24 September: Fighting the Forger: Secrets of Your Passport. Martin Lloyd at Barnard's Inn Hall, on 3,000 years of passports. (6pm)
25 September: The Red Planet. Carolin Crawford is at Museum of London to give an update on Martian exploration. (1pm)
26 September: The Currency of Management: What Managing Money Tells Us About Managing People. Michael Mainelli and Christopher Seow, at Barnard's Inn Hall, fail to manage the length of their talk's title, but should muster up a good lecture on how organisations work. (6pm)
1 October: What is Reading? Just dipping into October to highlight one final talk from the programme, in which Belinda Jack, at Museum of London, looks at the neuroscience of reading. (6pm)
The programme for October onwards includes talks on human diseases, religion, depression, modern art, architecture, cryptography and quasars. Truly, something for everyone. And remember, it's all free and you just need to turn up on the day.
