📐Geometric Algebra

What do you learn in Geometric Algebra

Geometric Algebra covers the algebraic structure that unifies vector spaces, complex numbers, and quaternions. You'll explore multivectors, outer products, and rotors, learning how to represent and manipulate geometric objects algebraically. The course delves into applications in physics, computer graphics, and robotics, showing how this powerful framework simplifies complex geometric calculations.

Is Geometric Algebra hard?

Geometric Algebra can be challenging, especially if you're not used to thinking in terms of geometric objects. The concepts are pretty abstract at first, and it takes some time to wrap your head around them. But once it clicks, it's actually super intuitive and makes a lot of geometric problems way easier to solve. The math isn't too crazy, but you'll need to be comfortable with linear algebra and vector calculus.
