Ludwig von Helmholtz

Hermann von Helmholtz was a German scientist and philosopher in the 19th century, renowned for his work in physics, physiology, and psychology. He contributed to understanding how the eye and ear perceive sound and light, explaining concepts like sight, hearing, and sensation through scientific principles. Helmholtz also developed theories about energy conservation and was a pioneer in studying electromagnetism. His work helped bridge the gap between physics and biology, laying the foundation for modern sensory science and understanding human perception.
