Book 'o the month.

 Physics of Superheroes. It was an excellent read. I took most of the month to read it, because, I had to reread sections occasionally to follow some of the ideas he was explaining. 

James Kakalios is a physics professor who loves comics. He wrote a very good lead up to the superhero comics by giving an overview of the general history of comics. 

Like the name implies, he then uses superheroes to explain physics. Superman explains ideas of force, and Newton's third law (for every action there is an equal and opposite reaction), by how in the early comics, he was actually leaping, more than flying, per se. 

The Flash explaining motion, Ant-Man, Giant Man, and The Atom were all explained why that they could (or couldn't) do the feats they did. And in the case of those 3, why the relative sizes would be physically impossible, if they have the original strength and weight. (Let's just say, suspension of disbelief is a very important tool for reading comics, especially if you have a PhD.) 

Ironman covered areas about electronics and how things have advanced from the 60's to more modern times, both with his suit, and in the real world. 

Okay, there was one section, quantum mechanics, I just read through, sorry world, I did not get very much out of it.  But, I must say, he made highly technical ideas pretty understandable. He has an excellent sense of humor (quite a bit of low key Dad jokes, too), and really seems to enjoy his subject. And wants you to, as well.

So, I give this book a Very Good.  

However, next book (which I have not chosen yet) is going to be MUCH less technical!

Oh, and Happy Leap Day!
