I took a test in the Army when I was at Signal Officer Advanced School in Ft Gordon, GA.
They asked the following question. If a 33 and a 1/3rd RPM record plays for 3 minutes, how many grooves on that side of the record? It was multiple choice with answers of 10, 100 and 1000.
I went up to the proctor and told him the correct answer was not on the test. He looked at me and said, lieutenant, we've been giving this test for decades, the right answer is there.
I said, you are looking for 100, wanting me to multiply 33.33 RPMs times 3 minutes to get 100, but there is only ONE groove on that side of the record. It's a spiral starting on the outside edge and makes it way to the center.
It makes 100 revolutions, but there is only one groove.
He told me to sit my smart backside down and fill in the answer they are expecting.
