Manga Guide to Science

I'm not sure if a similar thread already exist or not. if such a thread already exist, please delete or remove this thread.

While I was at Fry's Electronics the other day, I was browsing the manga aisle, and was I surprised at what I saw. Being a college student and an anime/manga fan, I stumbled to what was called The Manga Guide to Physics. It piqued my interests. I took a glanced at it because I was curious. To my surprise, it was about physics, but in manga format. I read a few pages. There is a storyline and a plot, in manga format, talking about physics. I was shocked. I looked over at the other mangas. I found that there were others about other topics.
I do not have much knowledge on these. I was able to find some of these "Manga's" on Amazon. I googled up a few of these, and people said that these "Manga's are pretty helpful for learning". It reminded me The Magic School Bus where they try to make learning FUN!!! And since it is on Amazon and Fry's Electronics, I guess I can safely assume that they are already licensed.

I could only find The Manga Guide to Science for:
Physics
Database
Calculus
Molecular Biology
Electricity
Statistics
Relativity
The Universe.

Anyone got their hands on any of these "Manga's" yet? How are these "Manga's" in regards to learning or pure enjoyment?
