Wouldn't it be awful if the first 3 recorded Women in the #HistoryofMaths were lost.

At least we get the 4th - Hypatia. SPOILER: her story does not make the patriarchy look any better. Would you like to know why?

A new episode of #themathematicianspodcast has dropped today. Would you like to discover 2500 year old calculus? I think in these uncertain times, we all should.

Come on down to your favourite podcast app and join me there.

First time I've seen it in the wild! The Mathematicians' Library on sale at a stand run by Kenilworth Books at #tmip25

I was so surprised I accidentally signed them all!

If you're following me and you're interested in #HistoryOfMaths, what's your favourite #history of #maths story?

I spent all day writing on Greek Mathematicians: Thales, Pythagoras, Eudoxus, Euclid & Archimedes.

What'd I miss today?

#HistoryOfMaths

"It can readily be proved by elementary geometry that AD*BE*CF = BD*CE*AF..."

Go on then, how can I readily prove this in a time before algebra and trigonometry?

A bit of a fun one today on #themathematicianspodcast

We look at Philo of Byzantium who was probably the first mad scientist in history.

Expect magic, catapults and a repeating crossbow.

Today I heard about a lovely quote from a Chinese historian of mathematics whose name has not yet stuck in my brain. The quote was something like...

"Studying the history of mathematics does not make better mathematicians, but it makes gentler, more thoughtful ones."

Today I learnt:

The symbol for infinity has a name, it is a "Lemniscate" to mean "ribbon".

One version takes its definition from the locci of points with a constant product of distances from two fixed foci.

Can you find 2 integers such that x^2 + y and x + y^2 are both perfect squares?

As of Saturday just gone I'm a member of The British Society for the History of Mathematics's council. I was invited to join as someone who can provide a school teacher's viewpoint.

As such, I'm very interested to know who...

I was reading up on #Archimedes and came across this gem. A beautiful proof of a geometric sequence using geometry.

See if you can figure out how it relates to the #quadrature of the #parabola

So #Pappus got up to some spicy maths back in the 3rdC BCE.

Inscribed circles each a distance of n diameters from the base.

I am looking forward to this episode of #themathematicianspodcast
