What do the people who say “learn to live with the virus” actually mean?

— Kit Yates (@Kit_Yates_Maths) July 30, 2021

They mean: fail to learn any of the lessons of the last 18 months, fail to mitigate against the spread of the virus and tolerate avoidable deaths and disease burden.

I’d rather we didn’t.

What happens in your head when you solve ζ(s) = ∑ₙ˲₀ n⁻ˢ = 0 ?

— Matt Salomone (@matthematician) August 2, 2021

Explain your process! New math vs. old math fascinates me. It’s cool seeing how other people’s minds work too!

What is a big open problem/conjecture in your field? Please briefly explain.

— Álvaro Lozano-Robledo (@MathAndCobb) August 2, 2021

E.g., the Birch and Swinnerton-Dyer conjecture in arithmetic geometry says that the rank of the group of rational points on an ab. variety coincides with the analytic order of vanishing of a L-function.
