As an engineering student many years ago, I was fascinated by quantum mechanics which sounded a lot more fundoo than applied mechanics or thermodynamics. It was then that I discovered Werner Heisenberg and his uncertainty principle, popularly known as HUP (Heisenberg’s Uncertainty Principle) which goes on to demonstrate how certain pairs of variables cannot be measured together. This was a landmark finding in 1927, which paved the way for a Nobel Prize in Physics to Heisenberg in 1932.
