Ernst Mach (18 February 1838-19 February 1916)
Ernst Waldfried Josef Wenzel Mach was born in Chirlitz (Chrlice) near Brunn (Brno) in the Habsburg crownland of Moravia (now the Czech Republic). He taught mathematics and physics in Graz (1864-1867), experimental physics in Prague (1867-1899), and the history and philosophy of inductive sciences in Vienna (1895-1898). He died in Vaterstetten, near Munich, Bavaria, during World War I. -
Ernst Mach (18 February 1838-19 February 1916) (Discovered optical inhibitory impressions now called "Mach Bands" 1865)
Mach bands are the illusory dark and bright bars seen at the foot and knee of a luminescence trapezoid. First demonstrated by Ernst Mach in the latter part of the 19th century, Mach bands are a test bed not only for models of brightness illusions but of spatial vision in general. -
Ernst Mach(18 February 1838-19 February 1916) (Discovered inertial movement of inner ear 1873)
He was the first person to relate dizziness and "motor sensations" to the inertial movement of liquid in part of our Inner ear. He discovered how the sense of balance (i.e., the perception of the head's imbalance) functions, tracing its management by information which the brain receives from the movement of a fluid in the semicircular canals of the inner ear. -
Ernst Mach (18 February 1838-19 February 1916) (Established connection between inertia and distant 1883) (Mach's Principle)
Ernst Mach stated that Newton's law of Inertia F=m.a, was established by all the matter of the universe. Mach (very cleverly) saw the connection between inertia and distant matter in the universe from considerations on the following experiment, which produces two fundamentally different ways of measuring a body's rotation in Space. -
Ernst Mach (18 February 1838-19 February 1916) (Developed measurement of sound waves 1887)
Between 1873 and 1893 he developed optical and photographic techniques for the measurement of sound waves and wave propagation. In 1887 he established the principles of supersonic s and the Mach number—the ratio of the velocity of an object to the velocity of sound. In 1887 he published photographs of projectiles in flight showing the accompanying shock waves; he found that at the speed of sound the flow of a gas changes character. -
