How we can better understand the world around us?

4 Oct 2023

Mathematics is about finding better ways of reasoning. But for many applied mathematicians, the primary mission is to shape their minds in a way that gets them closer to the truth. The calculations are secondary, the real question is: how we can better understand the world around us?

In this Oxford Mathematics Public Lecture, David takes us on a journey through applied mathematics from statistics all the way to complexity theory, lifting examples from his work with football clubs – signing the best players (statistical thinking) or organising an attack (complex thinking) – and from every day life – bickering less with our partners (interactive thinking) and learning to let go (chaotic thinking). David reimagines applied mathematics as a set of tools for life, from big work decisions to how we treat our friends, family and work colleagues. No problem is too big or too small for a mathematical solution.

Professor David Sumpter is author of five books including Soccermatics (2016), Outnumbered (2018) and Four Ways of Thinking (2023). His research covers everything from the inner workings of fish schools and ant colonies, through social psychology and segregation in society, to machine learning and artificial intelligence.

what is money? what is digital currency? something to represent value

4 Apr 2018

Bitcoin is the first decentralized digital currency. All Bitcoin transactions are documented on a virtual ledger called the blockchain, which is accessible for everyone to see. Bitcoin gives you complete control over your money, unlike other assets you own which are regulated by banks and governments.

As bitcoin gains more popularity, more and more places accept it as a payment method. That’s Bitcoin in a nutshell. For the complete simple explanation watch this video, here’s what I’ll cover:

0:50 – What is money? 3:10 – Fiat money 3:43 – Fiat money drawbacks 4:25 – Digital money 5:34 – Centralized money issues 7:21 – Enter Bitcoin 7:44 – Bitcoin is transparent 9:13 – Bitcoin is decentralized 9:35 – Bitcoin is digital 9:56 – Why is Bitcoin such big news? 11:45 – Who accepts Bitcoin? 12:05 – Conclusion

the most famous equation is E=mc2 | einstein

“E equals m c square” originally tried to explain what m (mass) was

20 May 2015

You’ve probably known OF E=mc² since you were born, and were also probably told that it meant that it proved Mass equaled Energy, or something along those lines.

BUT WAIT. Was E=mc² explained to you properly?

Mass equalling energy is mostly true, but E=mc² actually describes a much more interesting, and frankly mind-blowing aspect of reality that likely wasn’t covered in your high school physics class.

Join Gabe on this week’s episode of PBS Space Time he discusses THE TRUE MEANING OF E=mc²

what is Pi ? how do you calculate it ? | mathematics & science

it’s just square roots ?

For thousands of years, mathematicians were calculating Pi the obvious but numerically inefficient way. Then Newton came along and changed the game. This video is sponsored by Brilliant.

Happy Pi Day! (for a few days ago…)

the enigma of the riemann hypothesis | the holy grail in mathematics

/ brain perks by mvm
4 Jan 2021

The Riemann hypothesis is the most notorious unsolved problem in all of mathematics. Ever since it was first proposed by Bernhard Riemann in 1859, the conjecture has maintained the status of the “Holy Grail” of mathematics. In fact, the person who solves it will win a $1 million prize from the Clay Institute of Mathematics.

So, what is the Riemann hypothesis? Why is it so important? What can it tell us about the chaotic universe of prime numbers? And why is its proof so elusive?

Alex Kontorovich, professor of mathematics at Rutgers University, breaks it all down in this comprehensive explainer.

the shape of an infinite universe

Marcus Du Sautoy investigates the writings of Argentine master, Jorge Luis Borges, seeking its mathematical underpinnings.

Looking both at the life of the man and his texts, specifically ‘The Library of Babel’ Professor Du Sautoy shows how this singular author has found a way to describe the shape of an infinite universe that eerily mirrors the thinking of modern mathematicians. This is a short extract from a Gresham Lecture.

You can enjoy the lecture in full on our website: http://www.gresham.ac.uk/lectures-and… Marcus Du Sautoy OBE is the Simonyi Professor for the Public Understanding of Science and a Professor of Mathematics at the University of Oxford and he’s interested in how Maths and the Arts work together and how similar processes underlie them.
