Manuscript Letter – Italian Astronomer Giuseppe Armellini – Portorecanati – 19th August 1922
Short Description
Returning proofs and with suggestions of a mathematical nature based on “derivate ordinaries” … ordinary derivatives. Our calculus a little rusty as also our Italian … appears to be connected to Maxwell’s Laws.
Giuseppe Armellini (1887-1958) was born and died in Rome. He was Professor of Physics and Astronomy at several Italian Universities and Director of the Rome Astronomical Observatory for over 30 years. It was in the year of this letter [1922] that he took up his position at the Observatory of the Campidoglio which in 1936 he transferred to Monte Mario. A fire destroyed the Observatory in 1957 … inconsolable Armellini died the following year.
Armellini published several works … the first, in 1911, based on Newtonian principles. Over his career he developed several theories and principles. He will be forever known for Armellini’s Law {in 1922 also] which determines mathematically the distances of the planets from the sun in our solar system. The key to this understanding is the Armellini constant “D” … which is 1.53 but you must start at minus 2 for Mercury. Curiosities exist in its application … from them Armellini is awarded the honour of having predicted the large asteroid/ minor planet Chiron which was not confirmed until well after his death.
