Beilstein, F.K. Crookes created a glass vacuum tube which had a zinc sulfide coating on the inside of one end, a metal cathode imbedded in the other end and a metal anode in the shape of a cross in the middle of the tube. Schodinger (1930)Described electrons as continuous clouds.

Rutherford believed that the atom was mostly empty space. Nobel Prize in 1965. (1845-1923)Discovered x-radiation (1895).

In the 17th century, a synthesis of the ideas of these two disciplines, that is the deductive and the experimental, leads to the development of a process of thinking known as the scientific method. Nobel Prize in 1903 (with Becquerel) in physics; in chemistry 1911.

THE History of Chemistry - a great cache of chemical history is contained at this Umea University Chemistry Department site. Libby, Wilard F. (1908-1980)Developed carbon-14 dating technique. Established that the nucleus was small, dense, and positively charged. Found that 'canal rays' were associated with the proton H+. Many people think of chemists as being white-coated scientists mixing strange liquids in a laboratory, but the truth is we are all chemists. It contains an extremely tiny, dense positively charged nucleus (full of protons) and the nucleus is surrounded by electrons traveling at extremely high speeds. Chemistry is a vast field divided into several overlapping sub-branches: analytical chemistry, biochemistry, organic chemistry, physical chemistry, etc. (1745-1827)Invented the electric battery. Count Rumford (1798)Thought that heat was a form of energy. Stated the Uncertainty Principle (1927). The discovery poses a number of questions about the long and complex history of our species. J.J. Thomson placed the Crookes' tube within a magnetic field. Search the site GO.

Using Thomson's mass ration, Millikan found the mass of one electron to be 9.11E-28 grams.

Nobel, Alfred (1833-1896)Invented dynamite, smokeless powder, and blasting gelatin. Major discoveries in chemistry include events like the discovery of the atom. This elixir of life never happened either. Here's a helpful table chronicling the discovery of the elements. Chemistry is a branch of science that has been around for a long time. Urey, Harold C. (1894-1981)One of the leaders of the Manhattan Project. Langmuir, Irving (1881-1957)Research in the fields of surface chemistry, monomolecular films, emulsion chemistry, electric discharges in gasses, cloud seeding. However, most scientists believe that it started out from the ancient Greek who dwelled on the structure, composition, and different processes that occur within living organisms[3].

He concluded that all atoms have this negative charge (through more experiments) and he renamed the cathode rays electrons. Aristotle declares the existence of only four elements: fire, air, water and earth. Crookes hypothesized that there must have been rays coming from the cathode which caused the zinc sulfide to fluoresce and the cross to create a shadow and these rays were called cathode rays. Johann J. Beecher believed in a substance called phlogiston. Nobel Prize in 1963. Nobel Prize in 1932.

1903 Mikhail Semyonovich Tsvet invents chromatography, an important analytic technique.

Developed field of immunochemistry. Haber, F. (1868-1924)Synthesized ammonia from nitrogen and hydrogen, the first industrial fixation of atmospheric nitrogen (the process was further developed by Bosch).

Staudinger, Hermann (1881-1965)Studied high-polymer structure, catalytic synthesis, polymerization mechanisms.

Beilstein, F.K. Crookes created a glass vacuum tube which had a zinc sulfide coating on the inside of one end, a metal cathode imbedded in the other end and a metal anode in the shape of a cross in the middle of the tube. Schodinger (1930)Described electrons as continuous clouds.

Biochemistry News in 2017: Biochemistry is also known as biological chemistry. Natural philosophers (such as Aristotle and Democritus) used deductive reasoning in an attempt to explain the behavior of the world around them.

Pauli, Wolfgang (1933)Proposed the existence of neutrinos as a means of accounting for what appeared to be a violation of the law of conservation of energy in some nuclear reactions. (1850-1936)Fundamental research on equilibrium reactions (Le Chatelier’s Law), combustion of gasses, and iron and steel metallurgy.

Studied electrolysis of salts in water. Each link for each time interval contains some information about that period. This however did not provide any information about composition. P. Waage, "Experiments for Determining the Affinity Law" . Discovered acid-base indicators (litmus). The Thomson model was thrown out after the introduction of the Rutherford model. Volta, A. http://tqd.advanced.org/2690/hist/black.html.

Beilstein, F.K. Crookes created a glass vacuum tube which had a zinc sulfide coating on the inside of one end, a metal cathode imbedded in the other end and a metal anode in the shape of a cross in the middle of the tube. Schodinger (1930)Described electrons as continuous clouds.
