Hermann Von Helmholtz Facts

Hermann Von Helmholtz Facts
Hermann Ludwig Ferdinand von Helmholtz (August 31, 1821 to September 8, 1894) was a German physician and physicist. He made significant contributions to physiology, optics, electrodynamics, mathematics and meteorology but he is best known for law of the conservation of energy.
Interesting Hermann Von Helmholtz Facts:
Helmholtz was a sickly child and for the first seven years of his life was educated at home.
His father was a professor of philosophy and literature at the Potsdam high school and taught his son classical languages, French and philosophy.
In 1838 Helmholtz graduated from high school and entered the Frederich Wilhelm Medical Institute in Berlin which offered him a medical degree in exchange for 8 years of military service.
He graduated in 1843 and his doctoral dissertation was on the connection between nerve fibers and nerve cells.
The prevailing attitude of the day was that philosophy was the basis for all science and that scientific truth could be deduced from a few basic ideas.
Helmholtz vehemently rejected this idea in favor of empirical, verifiable science.
His study of heat generation in animals convinced him that all heat was a product of chemical or physical forces.
In 1847 he published his paper "On the Conservation of Force" and was the first explanation of the fundamental concept of conservation of energy.
In 1850 he was the first to measure the speed of nerve impulses using an instrument he invented for that purpose.
In 1851 his inventions of the ophthalmoscope and the ophthalmometer allowed physicians to see inside the eye and revolutionized the field of ophthalmology.
In 1856 he published his Handbook of Physiological Optics, which covered his experiments in depth perception, color vision, and motion perception.
He was a keen mathematician, and in 1858 published the paper, "On the Integrals of Hydrodynamic Equations to which Vortex Motions Conform," which provided a key to the fundamental structure of matter.
In 1863 he invented the Helmholtz resonator to identify the various frequencies of complex tones and published is paper On the Sensations of Tone.
In 1871 he became a professor of physics at Berlin where he formulated the Helmholtz equation.
