Show Me the Maths - Petra

Mathematics and mathematicians are not immune to the culture and politics of their times as Oxford Mathematician Petra explains in our latest 'Show Me the Maths' film.

An interesting topic in the history of Mathematics. All the best in your work, Petra!

[@user-en6tz3iy1z]

it's funny cuz the title says show me the maths but zero maths have been shown

[@Don.Challenger]

Hmm, it might be a NP hard problem to take the mathematician out of the maths and I believe that the International Mathematical Union (IMU) is about those mathematicians.

Edward Frenkel will have some stories to tell if you can get to him. He writes about the discrimination he faced in the USSR trying to get into school there.

[@themasculinesociety]

The title looks like from a meme lol

[@scottychen2397]

This is more a study of history than maths……
Unless her knowledge is on the technical level.
Then its both.

[@ramunasstulga8264]

I want to be like her 😭

[@user-bw7cq4qv2v]

Are you give me admission for the M. Phil and mathematics plz help me

[@DrakeLarson-js9px]

Sooo, what about inversion math, and physics???

I wish I could understand and appreciate mathematics at the level mathematicians do. Like I have read about Euler's identity and it seems incredible to me that these numbers arranged in that way could produce such a result, but it's been said that to a high level mathematician the reason is obvious.

[@user-en6tz3iy1z]

I don't think it's obvious but there's a very comprehensible proof for that identity.
the proof I know, and I guess it's the most simple one, involves pretty much nothing but Taylor Series(it's a way to make a polinomial that approaches functions, in this case e^x, sinx and cosx. this is probably how you calculator computes them. if you wanna know also why is that true, there's a nice proof on wikipedia), and highschool level trigonometry and complex numbers.
the core of the proof is using the taylor series of e^x, plugging ix instead of x, extracting the i with algebra and observing it's the taylor series of cosx, plus i times the taylor series of sinx.
now you have the formula e^ix=cosx + isinx, plug π instead of x and you get -1.

Where was Herzl in 1897? hmm,

[@qaimali3574]

Hi mam

[@guanchengzhu7749]

this is not even about history of maths, it's just history which IMU and Soviet mathematicians got involved

[@amitshridhar]

I need all kinds of help

[@user-rk4wv9ww6j]

I love math but I'can not studding now

[@kavorka8855]

why not?

[@lucitinhellfire8026]

I was waiting for the maths to be shown, disappointed 🤔
