Is there no modernized version of this document? Based on the first 100 pages I’ve read, it’s apparent that the author assumes that you have almost no knowledge of basic science. While “basic science” wasn’t really taught in the early 20th century (to average students), it is certainly taught by the high school level in many US States.
Yes, We are working on an updated version.
