Calculus isn't just abstract mathematics, it is an incredibly useful tool. Here I show you how to use it to derive the volumes of 3D shapes. Check out my posters here null This was the first example that really opened my eyes to the real value of calculus. I learned it in university in my physics department mathematics class, and it was just the beginning of a long journey of me wielding calculus at all sorts of practical problems in physics, and it gave me the power to see where the equations of physics came from, rather than just having to learn an memorize them.
