London Institute in 2021

2021 was transformative for the London Institute. We hired new talent, published pioneering research and moved into Faraday's rooms at the Royal Institution. We also compiled a list of the top 23 mathematical challenges of our time, to remind ourselves and others to aim high.

The London Institute is now located at the Royal Institution in Mayfair. It was here that Sir Humphry Davy identified nine elements of the periodic table and Michael Faraday uncovered the principles of electromagnetism. There could be no more inspiring place for us to work.

Our papers span five main research themes, from mathematics that unifies to the theory of human enterprise. Our output exceeded that of the previous year by 41%, part of our plan to double it every two years. We concentrate on the quality of our papers and not just the quantity.
