Things to Make and Do in the Fourth Dimension

I recognize that the way British people write maths in the plural is better and all but seeing jail spelled gaol sent me into cardiac arrest. We all have our limits.

I learn a lot of math and it was enjoyable. I also learned a lot of interesting math pieces.

It took a while for me to warm up to this book. The writing style is fun and inclusive but I felt like I was getting ghosted when it came to any hard maths with things being teased but ultimately left unknown. I know realistically most proofs are absolutely meaningless to most readers but I felt like I was being short-changed. However, I found as I got further in and the chapters were able to reference each other and the previous content many loose ends started to get tied off nicely and build what ended up being a completeness to the topics covered.
Obviously it's not exhaustive or massively comprehensive in its covering of this subject but I think the book and the author do a great job of making abstract topics not only accessible to readers, but also kind of fun. It's certainly an interesting read with a lot of new ideas and concepts for me, and a extended my knowledge of things I thought I was familiar with.
Overall I think the book achieves its goal of making obscure mathematics enjoyable and absorbing.

A wonderful mind-expanding treatise, written with humor and clarity. I enjoyed the refresher course on the fundamentals and then had my brain thoroughly exercised and expanded with what came after. As big a maths fan as I am, I still had to slow down and plow though some parts dealing with topics I'd previously ignored or given short shrift to. The most fun I've had in some time while getting a headache. After the pain receded, I felt that my brain contained more than I realized it could, and was the better for it. Filled with fun things to do with balloons, straws, paper strips, pencil and compass and more! My only regret is that the author didn't provide more computer code for those of us inclined to follow along - I'll have to come up with my own so I can continue playing.
