This is great. For anyone who wants to dive a bit deeper I would highly recommend the book The Shape of Space by Jeffrey Weeks. It's a wonderful insight into topology that can be enjoyed by anyone with high school math or above. I've even spotted it in the small library for graduate students at the Cambridge University maths department. Definitely my favourite maths book. https://www.goodreads.com/book/show/599877.The_Shape_of_Space https://www.goodreads.com/book/show/599877.The_Shape_of_Spac...
