Just returned from speaking at the wonderful Ciudad de Las Ideas festival in Puebla, Mexico. Honoured to have been invited to take part alongside a wide variety of speakers that included the filmmaker Oliver Stone, Nobel economist Paul Krugman, neuroscientist David Eagleman, and Olympic swimmer Mark Spitz, among others. Enjoyed some very stimulating conversations behind the scenes with mathematicians Amir Aczel (origins of the zero, and computer-generated proofs) and Arthur Benjamin (combinatorics).
Beautiful weather for my first trip to Central America. 24C in November - for a European like me it was quite the surprise! Loved the colourful buildings, baroque churches, and eating tortillas with refried beans for breakfast.
