(review mainly in English even if the book was in Italian, it just came out that way! Sorry)
I really enjoyed this book!
Maybe "enjoy" is an overstatement: math is more of a hobby and the contents are certainly challenging, for an apprentice with an old degree in Economics like me. I was reading slowly and then decided to tackle one equation per day. I needed the brain breaks in between equations.
I really loved the book design: how information was organized, and easily found throughout the book. "La mappa dei contenuti" at page 10 was really clear to follow through the various discoveries, chronologically and in terms of connections between the various theories.
Did I understand everything? Absolutely not. Do I know now what a "lagrangiana" his? No way. Did I get a hint of the awesomeness of it all? Abosultely yes. And I am so grateful for that!
Math, for me is a journey and I am searching for pebbles to toy my brain with. And this book has been like a bag of marbles to play with at the beach: I do not fully understand what's going on, but I do have fun and sometimes I get a glimpse of the bigger meanings. I am sure this is one of those books that I will come back to, when I'll continue on my math journey and find out new things or have deja-vus. And I am optimistic that the area of the things I'll understand will grow bigger and bigger, thanks to Sander Bais's book as well.
Il miracolo non è tanto la complessità del nostro mondo, quanto la semplicità delle equazioni che lo descrivono
