WB A very good analogy. The car designer uses an engine designed by someone else that essentially just produces a series of controlled explosions. These produce an in and out motion, which is then adapted to make a round and round motion, which itself is transmitted to the wheels. The power is also translated into the electricity that fires the ignition that starts off the explosions, works lights, displays things on the dahboard, and does all the other things that we take for granted.
the driver doesn't need to know much about it all, just how to use the magical machine to best advantage (and when to get someone else to fix it)
Shall we reboot our cartoons thread again? 😁
Bought the wrong Hot Cross Buns 😩
