Maths is your future: Visual effects artist

Summary

In this engaging exploration, mathematician Matt Parker visits Framestore, a leading visual effects company, to see how advanced mathematics is applied in real-world careers. He meets Jamie, a CG supervisor, who demonstrates how concepts like vectors, dot and cross products, and differential equations underpin simulations for fire, water, and building destruction in films. Parker also discovers the role of math in designing roller coasters, where derivatives and physics govern forces and accelerations. The video highlights that the math learned in school—combined with creativity—is not only foundational but also essential in creating both cinematic visual effects and thrilling theme park experiences.
