Daniel Griller studied Maths at Trinity College Cambridge, has written maths problems for the British Maths Olympiad, Radio 4, The Guardian and The New Scientist, and is currently a maths teacher. We discuss debates in mathematics, his experiences writing olympiad problems, as well as advice and techniques to use in your own problem solving. He has published three books: A Ring of Cats and Dogs: and Other Curious Puzzles, Problem Solving in GCSE Mathematics, and Elastic Numbers: 108 Puzzles for the Serious Problem Solver. They contain some great problems, and we encourage you to buy one. This episode was cohosted with Ishaan Das.

Rohan and I ask each other 2 rounds of unique physics, philosophy and maths questions which we solve mentally and out loud. Solve these along with us and see if you can get the answer before we can.

The equivalent resistance of an infinite array of resistors? Can you find the answer? Another video episode for you today, where I propose an interesting physics problem and give its step by step solution. This is a great problem to understanding circuits, especially resistors in parallel and series. Consider leaving a follow to see more content like this. 

I run through my solution to the Hailstorm problem on the whiteboard. An interesting and creative problem, I hope you find this episode intriguing.

In this episode, we get into Mary the Colourblind Neuroscientist, an interesting thought experiment about knowledge. I give my own introduction and then 6 opinions from my friends answering the key question, has Mary learnt any new information? 

The top 10 thought experiments, spanning physics and philosophy, that have puzzled some of the greatest minds throughout history, like LaPlace, Maxwell and Schrödinger. For the first time, this podcast comes with an animated video that I created, taking 4 months to animate. This is an episode of Scientific Discussion, the podcast created by Leo Sutherby and William Colvine. Voice over and animation by Leo Sutherby.

What common misconceptions and mistakes do most investors make? How has investor psychology changed as a result of the pandemic? And what advice would Caleb give to new investors?

In this episode, we examine the quality of different methods of obtaining random numbers, from rudimentary pseudorandom processes to the cutting-edge techniques that power data safety on the internet.

Ecology is not only important as a way to understand our environment, but also to understand how we're damaging it. How does deforestation affect the carbon cycle? How do fertilisers affect fish? How could impurities in fossil fuels kill organisms? I answer these questions, and more, in this episode, as I go over the fundamentals of ecology, as well as the main human influences on the environment, including global warming and climate change. 

What is our circulatory system? What does it do? How does it differ from other species? What is blood really made up of? What do red blood cells look like? Why do we breath heavily after exercise? What are the differences between arteries and veins? We answer these questions, and more, in this episode of the Scientific Discussion.
