最新第4版 The progression of 3 years between 1st and 2nd, 6 between 2nd and 3rd, and 10 between 3rd and 4th is a reflection not so much of the length of time it takes for each new edition (which has indeed steadily increased), but rather how long it takes us to forget all the stress and pain involved in making a new edition. As a data point, our Google Doc of new references since the last edition is around 170 pages long, and does not include references we could easily dismiss, nor those we ran into later when more closely reading and writing. Each page has about 20 references on it (some duplicated among chapters), about 3200 in all. In the fourth edition we added “only” 1151 new references, and deleted 508 older ones, for a final total of 2059 references (this does not include references on collision detection – more on that in a minute).
