A (very) Brief History of Charles Ehresmann 

I know little to nothing about math, and I still enjoyed all of and understood 98% or so of this video. You're a great presenter, thank you.

Many thanks! I enjoyed every second of it. Wish you all the best! ❤️🙏🏻

Please do grothendieck next. He wasn't an outlier as a kid so his story gives me hope

thank you Andrew, for delivering works of mathematicians of less unknown and i want to know more of 19 and 20 century mathematicians whose work on geometry, analysis(complex),number theory

This is to say nothing of the relationship of his work on what is now known as gauge theory to particle physics. Probably the student of his who understood this the best is Robert Hermann, having realized the connection before almost anyone else. Hermann writes interesting personal/historical information at the beginning of every one of his books.

When you try to speak french words it sounds like your head is about to pop off.

I love this series, keep going

Keep up the great work!

One on LEJ Brouwer please incredible work once again👏👏👏👏

That hairline is maddd, good work!

Please can you make a video about cauchy?

I also had never heard of him. He seems to be a theory-builder, having built many topics familiar to those introduced to (abstract) differential geometry/topology.

Maybe you can prepare a video for Bourbaki group and their works.

Good reading. Without the background music it would be better.

Your the best

May I ask that you not attempt a French accent? It's better than a lot of other anglophones' attempts, but it's still a bit distracting.

As I have commented before, I "Love" your short histories of famous mathematicians, 'however' being an English Speaker fluent in German and French, as well as serious amateur musician, I nearly keel-over dead everytime you "attempt" to pronounce something in French or German; ...why not just 'butcher' the pronunciation in the Standard North American manner, then North American viewers {listeners} would be able to more easily understand what you are saying; ...'THAT', and show the Names and Places [ i.e. schools & universities], then we can simply 'read' them without the shock of mispronunciation, ...truly 💕, I do not mean, 'at all', to criticize you personally, rather simply asking a favor; "please."
