Lecture Summary, 27 August 2015
we discussed basic problem solving techniques. We covered the
importance of careful analysis of units and the magnitude of the
result. Whenever you solve a problem, you should look at your
final answer and ask yourself qualitiative questions about whether
that answer makes any sense. Do the units make sense?
Should the number be > or < 0? Should it be >
or < 1? Does the magnitude of the number make sense?
If your number doesn't make good physical sense, then you have
made a mistake that you need to go back and find. Getting into
this habit will allow you to solve complex problems and have
confidence in your answer, even if you don't know what it is.
We also briefly began talking about Rutherford's gold foil experiment to determine the structure of the atom, but I'll save discussion on that for the next lecture.
