#TOTD As an engineer you quickly learn to appreciate how any dynamic system is just a series of energy connections. For example: any driver knows what the brake pedal does; a technician understands how it works, with the caliper pressing the pads against the disc; an engineer, however, understands that deceleration is nothing but a conversion of energy: from kinetic to heat. The car will lose velocity by the same rate as the brakes heat up. Power simply has to go somewhere.
This reminds of the tale of the pitcher who got hit by a line drive right on the head and the ball bounced of his head and flew up to the highest seats in the stadium. A physics professor watching exclaimed: "He is going to be fine".
Ha! That's a good one! I'll use that example from now on :)
