A to B to C

A to B to C

This one is in connection to some earlier posts on ‘Impactful brevity’ and on effective communication (So what’s your Point?). A friend recently sent me a hilarious video on WhatsApp that somehow reminded me of an incident from high school that I was surprised I remembered. Wonder how the memory had managed to survive in the junk in my head for so long.

Here’s what had happened. During a Physics lecture somewhere in high-school, our teacher was explaining to us, the oscillation of a pendulum. We drew the oscillating pendulum, which looked something like the one below, and we noted the definition as instructed, which read something like, “one oscillation of the pendulum, is when the pendulum moves from point A-B-C-B-A, or from B-A-B-C-B, or from C-B-A-B-C.” The definition seemed a little (very!) amusing, but I guess there weren’t many other ways to define it

While studying for the upcoming test, and this was probably the simplest definition; a realization hit me. It was that the definition completely depended on the drawing or image, and that it would be meaningless without it. Then another thought hit me. That I was probably really stupid to make such a big deal of something so obvious.

When we got our test scores, having scored reasonably well, I was quite upbeat. The teacher, while reviewing overall performance, mentioned the question on oscillation. I wondered, the definition couldn’t possibly have gotten any easier, so why was he bothering to mention that. He said, that a good number of students in class had defined oscillation with the ‘A-C-……’ definition, but had not drawn the diagram, and hence their definition was meaningless, and it didn’t get them any scores for that answer. Damn, I thought. Suddenly, my realization didn’t feel all that stupid.

    1. Thanks Su, and welcome back.! The image is pretty much the one taught in school. And the video that reminded me of it, was hilarious too. Similar to the misunderstandings that sometimes happen at work or in daily life.
