Vi träffades den 28 april på Berns veranda i Berzelii park:
Kvällens betyg:
- Service - 4
långsam kypare... men på väg hem finner Gunilla anledning att uppgradera servicen - Mat - 4
nästa dag finner Gunilla anledning att även uppgradera betyget på maten - Stekare - 0
vi funderar ett långt tag på om någon av kvinnorna i änden på rummet är några vi bör känner igen, men beslutar tillslut om att så inte är fallet - Snajdigt - 4
TOTAL - 12
Ps.
Jöns Jacob Berzelius 1779 – 1848) was a Swedish chemist. Berzelius is considered, along with Robert Boyle, John Dalton, and Antoine Lavoisier, to be one of the founders of modern chemistry.
Berzelius began his career as a physician but his researches in physical chemistry were of lasting significance in the development of the subject. He is especially noted for his determination of atomic weights; his experiments led to a more complete depiction of the principles of stoichiometry, or the field of chemical combining proportions. In 1803 Berzelius demonstrated the power of an electrochemical cell to decompose chemicals into pairs of electrically opposite constituents.
Berzelius's work with atomic weights and his theory of electrochemical dualism led to his development of a modern system of chemical formula notation that could portray the composition of any compound both qualitatively (by showing its electrochemically opposing ingredients) and quantitatively (by showing the proportions in which the ingredients were united). His system abbreviated the Latin names of the elements with one or two letters and applied superscripts to designate the number of atoms of each element present in both the acidic and basic ingredients.
Berzelius himself discovered and isolated several new elements, including cerium (1803) and thorium (1828). Berzelius’s interest in mineralogy also fostered his analysis and preparation of new compounds of these and other elements. He was a strict empiricist and insisted that any new theory be consistent with the sum of chemical knowledge. He developed classical analytical techniques, and investigated isomerism and catalysis, phenomena that owe their names to him. He became a member of the Royal Swedish Academy of Sciences in 1808 and served from 1818 as its principal functionary, the perpetual secretary. He is known in Sweden as "the Father of Swedish Chemistry".
