Great talk by Tony DeRose. He shows how addition, multiplication, geometry and trigonometry are playing a role in Pixar movies.

Of course, this is just the surface. They use much further mathematics at Pixar, but being a 15 year old student, this makes sense why you have to learn these not so simple stuff in maths. You can find out more about how mathematics is used at Pixar in this artcle.

This is what kids need. People who show how mathematics (or any other subject) taught at schools can be used in real life. *“Why do I have to learn this?”* is the most common question we have to face. In the 19th century only royals and chosen ones were so lucky to be able to study. They didn’t ask these questions. They knew, what they get is something special.

Education today is mandatory for everyone. Kids rarely can choose what they are taught. If they can’t choose what they want, we have to be able to tell them why they need to do it. And if we are unable to do so, we need to rethink our attitude to teaching.

While I was writing this blog post, I found another great video that shows the beauty of mathematics.
