As far as I can recall, it was the first grade and there was this question that was staring at me from the book:
“If one cat can catch one mouse in one minute, how many
minutes does it take for three cats to catch three mice?”
Simple, is it not? Of course we all know that the answer is one minute. To someone grokking the basics of mathematics and logic, not so apparently easy. The fact is that it took me quite a bit of time to realize that it was not a simple case of arithmetic correspondence to (wrongly of course) equate three cats catching three mice in three minutes! What I realized after some ponderous consideration is that all the three cats were working in “parallel” to catch the three mice!
That then was my first lesson in parallelism.
