Hey Folks!...Imagine a moving contraption – say a toy car - which has multiple engines. Different ones for different body parts. Each engine, engineered to keep up with each other….leading to a nice smooth ride. Well at least smooth, when the going is good….lets bring in a small new variable to this hunky dory scenario. Normal wear & tear and minor variations of stress load on different parts can lead to the change in the performance levels of different parts. [Like the same way different cars of the same make end up giving different mileage depending upon driver, route, maintenance etc]. What would this really mean in practical terms? The toy driver and the co-passengers – would need to jostle and we would see a good deal of hustle and bustle. There will be small whirlpool of energies and eddies trying to ruffle the imbalance of different engines. Quite amusing really! Especially, when we are talking about an inanimate contraption. Now lets bring in one more variable. Let the toy ...
