Physics textbook errata - Halliday and Resnick
Errors in Physics Textbooks - a listing of known physics textbook errata.
However, I don't have the time to check out all physics
textbooks myself. If you are aware of errors that I have not included from
this or any other physics textbook, please
e-mail me the details.

Anonymous errata list:
- In the inside back cover, the value of G is listed with a 11^-11 instead of 10^-11.
- In homework problem 66 in ch. 14, the given data result in a
density of 0.4 g/cm3, which is far too small for a rocky asteroid. The period of Dactyl's orbit is
unknown, but is presumably significantly shorter than the one suggested.
- In section 12-6, H&R claim to derive conservation of angular
momentum from Newton's laws of motion. Their proof is erroneous, since equal and opposite
forces do not necessarily produce equal and opposite torques. The proof only works in the cases
where both forces' moment-arm vectors are the same, or where the force is center-to-center.
As a counterexample to their proof, an isolated spinning bar magnet will gradually slow down
due to the emission of radio waves, which carry off angular momentum. Since light is massless, the
angular momentum carried by the radio waves cannot be discussed in the framework of Newtonian
