Ernst Mach

  • Birth

    Ernst Waldfried Josef Wenzel Mach was born in Czechia. His father was Johann Mach and worked as a tutor to the Brethon family in Zlin. His mother was Josephine Lanhaus. The family moved to Vienna, Austria when Ernst was an infant. In 1855, Mach enrolled at the University of Vienna studying physics, philosophy and mathematics and received his doctorate in physics in 1860.

  • Mach Bands

    Mach Bands
    Mach published a paper, the first of a series of remarkable articles on what are now known today as Mach Bands. Mach explained that optical illusions were not tricks of the brain but instead innate features of the senses. Mach argued that perception works through perceiving the relations between stimuli. The process that drives evolution, drives perception, and even drives science.

  • Inner Ear Anatomy

    Mach discovered a non-acoustic function of the inner ear which helped control human balance. He experimented with pigeons and rabbits; studied the brain, skin, and muscles; and examined the relations between motion and vision.

  • Physics

    Mach studied interference, diffraction, and polarization and refraction of light in different media under external influences. He studied supersonic velocity experiments. He correctly describes the sound effects during the supersonic motion of a projectile. The ratio of the speed of projectile to the speed of sound vp/vs is now called the Mach number, which played a crucial role in aerodynamics and hydrodynamics.

  • Death

    Death
    n 1867, Ernst Mach married Ludovica Marussig in Graz. They had five children, four sons and one daughter. In 1897 Mach suffered from a stroke, leaving the right side of his body paralyzed.
