An Application of Geography to Mathematics: History of the Integral of the Secant

How did anyone ever figure out that

∫secθ dθ = ln | sec θ + tan θ | + C ?

The surprising answer involves the Mercator map projection! Check out this great short article from @maanow's Mathematics Magazine (1980).https://t.co/pqKsdtDOZW pic.twitter.com/7Pn5QuKHcZ

Child mortality: an everyday tragedy of enormous scale that we can make progress against

One of humanity's most impressive achievements.

The reduction in child mortality across the world.

It used to be the case that one-in-three (if not more) died before their 5th birthday.

Now all countries have made massive progress against it.https://t.co/k0dgNannJm pic.twitter.com/IV4VfZWtbT
