Over the years I've terrorized many a poor first year student with talk of "errors" while demonstrating the lab in
PHY140 (physics for physicists) and
PHY180/182 (physics for engineering scientists).
I've also proven to a few aspiring engineers that they probably do know more first year physics than I do while
TA'ing
PHY180.
Are you a PHY180 student looking for tutorial notes? You've come to the
right place.
