Artificial neural network and archimedes’ screw: what they have in common

1. Step 1. Artificial neural network — is used in — Perceptron. The first trainable neural network.
2. Step 2. Perceptron — has part — Potentiometer. Potentiometers set the weights.
3. Step 3. Potentiometer — is made of — Nickel. The resistance wire is a nickel alloy.
4. Step 4. Nickel — is material for — Turboprop. The turbine blades are nickel alloys.
5. Step 5. Turboprop — has part — Propeller. A propeller.
6. Step 6. Propeller — evolved from — Archimedes’ screw. The first propellers by Smith and Ericsson were a variation on the Archimedes’ screw.
