The year 1835 in science and technology included many events, some of which are listed here.

1 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.

2 Chemistry

• Vinyl chloride first produced by Justus von LiebigFreiherr Justus von Liebig ( May 12, 1803 in Darmstadt, Germany April 18, 1873 in Munich, Germany) was a German chemist. He made major contributions to agricultural and biological chemistry, and worked on the organization of organic chemistry. He was expe and his student Henri Victor RegnaultHenri Victor Regnault ( July 21, 1810 January 19, 1878) was a French chemist and physicist best known for his careful measurements of the thermal properties of gases. Born in Aix-la-Chapelle in 1810, he moved to Paris following the death of his parents at

3 Mathematics

• Dirichlet proves Dirichlet's theorem about prime numbers in arithmetical progressions

4 Physics

• William Rowan HamiltonSir William Rowan Hamilton ( August 4, 1805 September 2, 1865) was an Irish mathematician, physicist, and astronomer. Hamilton's discovery of quaternions is his best known investigation. Hamilton also contributed to the development of optics, dynamics, an states Hamilton's canonical equations of motion
• Gaspard-Gustave CoriolisGaspard-Gustave de Coriolis ( May 21 1792- September 19 1843), French engineer and scientist. His interest in the dynamics of rotating machines led him to derive the differential equations of motion from the point of view of a coordinate system which is i examines motion on a spinning surface deduces the Coriolis effectIn physics, the Coriolis effect is an inertial force first described by Gaspard-Gustave Coriolis, a French scientist, in 1835. When the equations of motion are formulated in a rotating coordinate system a term arises which looks like a force, called the C

5 Technology

• Samuel ColtSamuel Colt ( July 19, 1814 January 20, 1862), born in Hartford, Connecticut, was the inventor of the revolver, and founder of the Colt Firearms company. Colt's father owned a textile mill, where the young Colt learned the principles of machinery. His wor invents the revolver
• Samuel Morse develops the Morse code
