I did my own experiments to determine what that something might be. Actually, I was quite familiar with it already. I'm a mushroom scientist. I live in isolation on a farm, because distractions in the environment create mental pain. The distractions include noises, traffic, the refrigerator starting or the furnace going on.
Timing is critical.
A distraction will occur while touching a water faucet or going through a doorway. So I use electronic devices to control appliances, and I put signs by water faucets or doorways as a reminder to watch for distractions. For a preliminary test of Joule's constant, I used an electric drill, which was extremely crude and did not allow for internal heat measurements. Someone wanted me to know there was a Joule's constant. So I refined the equipment using a one inch motor embedded in a block of aluminum to measure heat production, and I stirred water in a styrofoam container.
