Random Quote:

In early 2021, the University of Leicester threatened with redundancy some of the best mathematicians and computer scientists I know, former colleagues of mine. By the end of the academic year, if I counted correctly, 16 academics in mathematics and computer science either left their job “voluntarily” or were made redundant … support the Leicester boycottmore.

Both natural and programming languages are recursive. In German also words are recursive, for example, we can make words such Rindfleischetikettierungsüberwachungsaufgabenübertragungsgesetz. There is no longest word in German, much as there is no longest sentence in English. Btw, there is an interesting debate about whether Piraha is a language in which the length of sentences is also bounded (but the lengths of stories would still be unbounded).

If we want to survive on this planet, we need to respect planetary boundaries and transition to a sustainable economy. To achieve this, we need to get away from the idea that a good economy is a growing economy. Growth is not sustainable because sustained growth is exponential growth. For example, an average growth of 2% per year equals growth of 724% over 100 years and of 1,995,657% over 500 years. While the Limits to Growth have been recognised for a long time, recent accounts are Dasgupta’s Review on The Economics of Biodiversity and the IPBES Global Assessment Report on Biodiversity and Ecosystem Services.
