Doctor,
Your volume on mechanics of natural systems was quite informative, but during my study I've spotted a small error. In the paragraph about Work it says:
This is measured in Schnitzels (Sz) or kgs^-2, and is interchangeable with energy.I believe, according to the equations you have provided, that Schnitzels should be defined as kgm^2s^-2. It's a small typo, yet quite critical if one uses the information in practice and measure units on both sides of an equation aren't the same.
Congratulations on the work, I'm looking forward to seeing next volumes available in the library.
