Hermann von Helmholtz ( 1821 - 1894 ) Notes for Multimedia Fluid Mechanics

چکیده
The breadth of Helmholtz’s interests and contributions is outstanding. He is one of the rare scientists able to be creative in domains, as diverse as medicine, anatomy, physiology, acoustics, fluid mechanics, physics, music, aesthetics, epistemology... Although he was a universal mind, he insisted on his preference for physics, both theoretical and experimental. He was among the too rare scientists able to combine fundamental research and practical applications related to everyday life. Two years before his death, he gave us the following warning, which is still pertinent today: ‘Whoever in the pursuit of science, seeks after immediate practical utility may rest assured that he seeks in vain.’ The applicability of science is a consequence of research and not its sole goal, since the creativity requires the freedom to speculate on fundamental issues. The life of Helmholtz perfectly illustrates his point.

As described in my previous paper [1], the voltage-source equivalent was first derived by Hermann von Helmholtz (1821–1894) in an 1853 paper [2]. Exactly thirty years later in 1883, Léon Charles Thévenin (1857–1926) published the same result [3], [4] apparently unaware of Helmholtz’s work. The generality of the equivalent source network was not appreciated until forty-three years later. Then, i...

Driven by both empirical knowledge and mathematical reasoning, Helmholtz made extraordinary contributions to natural philosophy, including both imaging and vision science. Fundamentally important examples include the Helmholtz theorem and the Helmholtz equation, which describe vector and scalar properties of light fields. The first informs us that fields are derived from point and current sourc...
