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)
We are what we pretend to be, so we must be careful about what we pretend to be.
The meaning of life is to find your gift. The purpose of life is to give it away.
To be yourself in a world that is constantly trying to make you something else is the greatest accomplishment.
The unexamined life is not worth living.
Know thyself.
The magnitude of the current flowing through a conductor is directly proportional to the voltage applied across its ends and inversely proportional to the resistance of the conductor.
A conductor's resistance is directly proportional to its length and inversely proportional to its cross-sectional area, and also depends on the material it is made from.
The mathematical treatment of electrical circuits, using precise quantitative relationships, is essential for understanding their behavior.
Electrical current is not a fluid, but rather a flow of something that can be precisely measured and quantified.
The resistance of a conductor is a fundamental property, not merely an impediment to the flow of 'electrical fluid'.
My theory provides a unified framework for understanding all galvanic phenomena, from simple circuits to complex networks.
The prevailing qualitative descriptions of electricity are insufficient; a rigorous mathematical approach is required.
The opposition I face stems from a reluctance to embrace mathematical rigor in the study of natural phenomena.
The 'electrical tension' or 'electromotive force' is the driving cause of the current, and its effect can be precisely calculated.
The resistance of a wire is not simply a measure of its 'thickness' or 'length', but a specific constant for each material.
The experimental results I present are not mere observations, but confirmations of a precise mathematical law.
To truly understand electricity, one must move beyond analogies and embrace the language of mathematics.
The idea that electricity flows like water is a useful analogy, but it obscures the underlying quantitative relationships.
My work demonstrates that the laws governing electrical circuits are as precise and predictable as those governing mechanics.
The resistance of a conductor is not an arbitrary quantity, but a measurable and reproducible characteristic.
