This book wasn't bad, but I can't help but feel like I wanted more, especially of the slightly harder technical stuff.
I am moderately interested in the technology behind roller coasters, and I found quite a lot of the information to be a bit shallow, or things that seemed very easy to know. With the book being only about 100 pages, the times were things got a bit more technical, seemed too few and too short.
I initially picked up this book because I had found a bit online showing some calculations for a few calculations about coaster design, however these that I found turned out to be the only ones in the book.
Seems ok for a quick overview of some concepts, but to get deeper knowledge other sources should be sought for.
