Coronavirus has made amateur mathematicians of us all

‘What is the point of learning maths? When do you ever actually need it? How does it ever affect your life?’ That’s the frequent complaint of my school-age children, labouring over their times tables and number bonds. It was my complaint as I struggled to tell median from mean, or sine from cosine.

Well. Now we have a nation and a world bewitched and terrified in equal measure by a ground-level demonstration of what an exponential function does. Our entire society is being shaped for a generation by that elegant, predictable, horrifyingly steepening curve. One shred of comfort in this catastrophe is the thought that no journalist will ever again write ‘increasing exponentially’ as a fancy-sounding way of saying ‘increasing a lot’.

Coronavirus has made amateur mathematicians of us all. Like many people, I’m gripped by the nightly bulletins of the FT’s data–visualisation reporter John Burn-Murdoch — who posts lucid graphs comparing infection rates and death rates globally.
