1835 in science

The year 1835 in science and technology involved some significant events, listed below.

Astronomy

* August 5 - First sighting of the return of Comet Halley by Father Dumouchel, director of the Collegio Romano at the Vatican. It was next seen by Friedrich Georg Wilhelm Struve on August 21 at the Dorpat Observatory. John Herschel had been expected to find the comet first, as he was at the time in South Africa with his 20ft focal length reflector - then the largest telescope in the world. He finally observed it in October, and watched until it reached its perihelion November 16. It reappeared in January 1836, and Herschel was the last person to observe it in May.
* August 25 - The first article in a longer fake series on discoveries made by John Herschel and a fictitious companion named Dr. Andrew Grant was published in the "New York Sun". This incident is now known as the Great Moon Hoax.

Chemistry

* Vinyl chloride first produced by Justus von Liebig and his student Henri Victor Regnault.

Mathematics

*Dirichlet proves Dirichlet's theorem about prime numbers in arithmetical progressions.

Physics

*William Rowan Hamilton states Hamilton's canonical equations of motion.
*Gaspard-Gustave Coriolis examines motion on a spinning surface deduces the Coriolis effect.

Technology

*Samuel Colt invents the revolver.
*Samuel Morse develops the Morse code.
