The year 1902 in science and technology involved some significant events, listed below.
Aeronautics
[edit ]- May 15 – Lyman Gilmore claims to have flown his steam-powered fixed-wing aircraft, although his proof is supposedly destroyed in a 1935 fire.
Chemistry
[edit ]- Hermann Emil Fischer and Joseph von Mering discover that barbitone (barbital or Veronal) is an effective hypnotic agent.[1] It becomes the first commercially marketed barbiturate, being used as a treatment for insomnia from 1903.
- Auguste Verneuil develops the Verneuil process for making synthetic rubies.
- German chemist Wilhelm Ostwald develops and patents the Ostwald process for making nitric acid.
Earth sciences
[edit ]- April–August – Eruption of Mount Pelée in Martinique.

Exploration
[edit ]- July 14 - Peruvian explorer Agustín Lizárraga rediscovers the Inca citadel of Machu Picchu, Peru
- December 30 – Discovery Expedition: British explorers Scott, Shackleton and Wilson reach the furthest southern point reached thus far by man, south of 82°S.
Genetics
[edit ]- Walter Sutton (in the United States) and Theodor Boveri (in Germany) independently develop the Boveri–Sutton chromosome theory, explaining the mechanism underlying the laws of Mendelian inheritance by identifying chromosomes as the carriers of genetic material.[2]
History of science
[edit ]- May 17 – Archaeologist Valerios Stais identifies the Antikythera mechanism, now considered to be the oldest known analog computer.[3]
Mathematics
[edit ]- June 16 – Bertrand Russell writes to Gottlob Frege informing him of the problem in naive set theory that will become known as Russell's paradox.[4]
- Gyula Farkas publishes the first proof of Farkas' lemma.[5]
- Henri Lebesgue introduces the theory of Lebesgue integration.[6]
Medicine
[edit ]- January 1 – Nurses Registration Act 1901 comes into effect in New Zealand, making it the first country in the world to require state registration of nurses. On January 10, Ellen Dougherty becomes the world's first registered nurse.
- February – A commission on yellow fever in the United States announces that the disease is carried by mosquitoes.
Paleontology
[edit ]- Remains of the second Tyrannosaurus rex specimen, the first recognized as such, are excavated by Barnum Brown in the Hell Creek Formation of Montana.[7]
Physics
[edit ]- Oliver Heaviside and Arthur E. Kennelly independently predict the existence of what will become known as the Kennelly-Heaviside Layer of the ionosphere.
- James Jeans finds the length scale required for gravitational perturbations to grow in a static nearly homogeneous medium.
- Philipp Lenard observes that maximum photoelectron energies are independent of illuminating intensity but depend on frequency.
- Gilbert N. Lewis develops the cubical atom atomic model.
- Theodor Svedberg suggests that fluctuations in molecular bombardment cause the Brownian motion.
Physiology
[edit ]- William Bayliss and Ernest Starling make the first discovery of a hormone, secretin.
Psychology
[edit ]- Vienna Psychoanalytic Society begins to meet as the Wednesday Psychological Society in Sigmund Freud's apartment.
Technology
[edit ]- January 1 – Nathan Stubblefield demonstrates his wireless telephone device in Kentucky.
- April 13 – A new land speed record of 74 mph (119 km/h) is set in Nice, France, by Léon Serpollet driving a steam car.
