Things to Make and Do in the Fourth Dimension

Another great book that's worth a read is "Things to make and do in the 4th dimension" by Matt Parker. It is a really interesting book as it covers multiple topics from mathematics and being that you are a young reader you might benefit from that exposure to topic. From there on you can fine the topics that interest and dive deeper and learn the nitty gritty! Thats how I personally found my passion in topology.

This might be a bit of a different take than the other comments here, but I highly enjoyed reading Things to Make and Do in the Fourth Dimension by Matt Parker when I first became interested in maths.

"Things to Make and Do in the Fourth Dimension" is really fun, but it's not really tech, it's more just math. But I do a lot of work with scientific / numerical computing so some may group them together. In addition to math, it covers some interesting algorithms and fun ways to use spreadsheets for images, etc. I also really enjoy books about the tech used in the early space program. "Digital Apollo" is probably the one that makes the best light / easy reading.
