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
Dominique Dumouchel, director of the
Collegio Romano at the
Vatican. It is next seen on August 21 by
Friedrich Georg Wilhelm Struve 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 20 ft focal length reflector – at this time the world's largest telescope. He finally observes it in October and watches until it reaches
perihelion November 16. It reappears in January 1836, and Herschel will be the last person to observe it in May.
August 25 – The first of six articles on discoveries of living creatures on the Moon supposedly made by Herschel and a fictitious companion named Dr. Andrew Grant is published in the New York Sun. This incident is now known as the
Great Moon Hoax.
Adolphe Quetelet publishes Sur l'homme et le développement de ses facultés, ou Essai de physique sociale (translated as Treatise on Man), outlining his theory of "social physics" and describing his concept of the "average man" (l'homme moyen) who is characterized by the
mean values of measured variables that follow a
normal distribution.[4]
French physician
Pierre Charles Alexandre Louis publishes his book Recherches sur les effets de la saignée dans quelques maladies inflammatoires et sur l'action de l'émétique et des vésicatoires dans la pneumonie in
Paris, in which he analyzes case studies to demonstrate that
bloodletting is largely ineffective as a treatment.[8]
Belgian statistician
Adolphe Quetelet publishes his books Sur l'homme et le développement de ses facultés, ou Essai de physique sociale, in which he presents his theory of human
variance around the
average, with human traits being distributed according to a
normal curve.[9]
