1877 in science

The year 1877 in science and technology involved some significant events, listed below.

Events

• June 19 – Eadweard Muybridge successfully produces a fast-motion sequence of photographs showing a horse in movement, Sallie Gardner at a Gallop, using multiple cameras at Palo Alto, California, demonstrating that a running horse has all four legs lifted off the ground at once. The sequence could be run on a Zoopraxiscope.^[1]

Astronomy

• August 12 – American astronomer Asaph Hall discovers Deimos, the smaller of the two moons of Mars. On August 18, he discovers the larger, Phobos.

Cartography

• Peirce quincuncial projection devised by Charles Sanders Peirce.^[2]

Chemistry

• Ludwig Boltzmann establishes statistical derivations of many important physical and chemical concepts, including entropy, and distributions of molecular velocities in the gas phase.^[3]

Earth sciences

• June 26 – Volcanic eruption of Cotopaxi in Ecuador.

History of science

• Dr. August Eisenlohr publishes the first translation and study of the Rhind Mathematical Papyrus.^[4]
• American railroad lawyer and ethnologist Lewis H. Morgan publishes Ancient Society, linking social progress with technological change.

Mathematics

• Georg Cantor advances the continuum hypothesis.

Medicine

• October 2 – Berlin urologist Maximilian Nitze and Viennese instrument-maker Josef Leiter introduce the first practical cystourethroscope with an electric light source.^[5]
• Adolph Kussmaul first describes dyslexia as "word-blindness".
• William Macewen at the Glasgow Royal Infirmary develops the first bone grafts, and also performs knee surgery using a special instrument (Macewen's osteotome), for the treatment of rickets.
• Patrick Manson studies animal carriers of infectious diseases.

Physics

• Ludwig Boltzmann states the relationship between entropy and probability.

Technology

• March 28 – Frederick Wolseley is granted his first patent for a sheep shearing machine.
