Some great innovations and business revolutions of the present day global economy have been propelled by those rogue and rebellious quasi-entrepreneurs who went out of their way, denying their superiors orders and even, at times, their company policies to help the firm get their next best product/technology/service.

There used to be such experiments like finding the index of refraction of glass and we had to place a glass slab on a white sheet of paper and then align pins on either side of the glass slab. After that, we were required to join the light ray paths according to the tiny holes punctured into the sheet by those pins, and then draw perpendiculars and apply Snell’s Law and God knows what else to calculate just a tiny number.

We soon realized that we can just copy the sample diagram given in our textbook on a sheet of paper and then poke those pins on the lines already drawn. Needless to say, we always used to come up with the perfectly accurate figure.

And now that I think of it, this would make a good blog update. Thanks UTP!

By the way, the arrow and bull’s eye illustrations are really well drawn.

Now please explain the fly in the car problem.
