I really liked this book. He really likes math and I do too!

This book was very interesting. It had lots of information about World War ll, and wrote about things about Albert Einstein that I had never known before. It's a good book for people who have already read lots of Albert Einstein biographies and who want to know more.

I thought this book was good and informative. Something that stood out for me was how Einstein made a lot of hypotheses about what was true, but people didn't believe him. Then it turned out that most of them were true. People were surprised.

I found this book to be really interesting. It was neat to learn more about him.

Book was okay but it was hard to finish.
