Georg Ohm
Formulated Ohm's Law, which states the relationship between voltage, current, and resistance in an electrical circuit.

"The further the spiritual evolution of mankind advances, the more certain it seems to me that the path to genuine religiosity does not lie through the fear of life, and the fear of death, and blind faith, but through striving after rational knowledge."

"Some gentlemen of science seem to believe that the only way to understand electricity is to be shocked by it. I prefer a more theoretical approach, less electrifying, perhaps, but certainly less hair-raising."
— from Attributed
"My law is like a good joke: simple, elegant, and once you hear it, you wonder why you didn't think of it yourself. And then you try to explain it to someone who doesn't get it, and it's no longer funny."

All quotes by Georg Ohm (358)
The electrical properties of materials can be systematically studied and categorized based on their resistance.
The 'electrical state' of a conductor can be precisely described by its potential.
The application of calculus to electrical phenomena is not merely an academic exercise, but a powerful tool for discovery.
The simplicity and universality of my law are its greatest strengths.
The resistance of a conductor is a constant for a given temperature and material, regardless of the applied voltage.
My theory offers a coherent explanation for phenomena that were previously described in a fragmented and qualitative manner.
The 'electrical current' is not a substance, but a measure of the rate of flow of charge.
The opposition to my work highlights the inherent conservatism within certain scientific circles.
The precise definition of electrical units is crucial for consistent and reproducible experimental results.
The mathematical formulation of electrical laws is the only path to true understanding and predictive power.
The force of the current in a galvanic circuit is directly proportional to the sum of all the tensions, and inversely proportional to the total reduced length of the circuit.
The path which electricity takes is not always the shortest, but always the easiest.
I have formed a theory which appears to me to account for the phenomena of the galvanic circuit in a manner which is as simple as it is comprehensive.
The theory I now publish... rests upon an assumption which I have endeavored to establish by numerous experiments.
The contact of two different metals produces a tension, and this tension is the cause of the current.
The current intensity is equal to the electromotive force divided by the resistance.
The resistance... depends on the nature of the conductor itself.
My work will have to fight its way through the jungle of scientific opinions.
The laws of the conduction of electricity in circuits are as simple as the laws of the equilibrium of liquids in connected vessels.
It is the tension which drives the electricity through the conductor.
