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. 

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? 

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?

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.
