I second that. When I was in engineering school, I took copious notes, but I never reviewed or studied the notes. So I decided it was all a waste; I stopped taking notes. It was a distaster. I went back to taking notes, though I did not review them. I believe that the process here is that the brain must think in detail what you write and that is what imprints the information in memory. Using a keyboard or a tape recorder does not have the same effect. Use a pen and write notes.

Read the paper and the comments on the physics site where the paper was originally posted. Several commenters pointed out that he was driving a Yaris, which could not stop and accelerate in the time shown in the paper. Or without doing complete analysis, the other car was moving at about 20 mph or about 30 feet/sec. A car is about 20 feet long, hence, the cops vision was blocked for less than a second, even without taking into account that the time was really due to the difference in the length of the two cars. If you can get a Yaris to go from 15 mph to a complete stop and back to 15 mph in under a second, you should be drag racing Yarises. If you can' dazzle them with briliance, you can baffle them with ...
