Oxford Mathematician Ben Green on a tale of conjectures, mistaken assumptions and eventual solutions: a tale of mathematics.
It is a cliche that crises create opportunities. But they certainly demand innovation (and a lot of hard work). In Oxford Mathematics, in line with many others departments and universities, we have had to switch from in-person teaching to online in most cases. This has been 100% the case in terms of undergraduate lectures which normally take place in large lecture theatres where a whiteboard, a marker pen (or two or three) and a mathematician take centre stage.
