Law of octaves
- John Newlands (born November 26, 1837, London, England—died July 29, 1898, London) was an English chemist whose “law of octaves ” noted a pattern in the atomic structure of elements with similar chemical properties and contributed in a significant way to the development of the periodic law.

MacDiarmid was a New Zealand chemist who shared the 2000 Nobel Prize in Chemistry with Alan Heeger and Hideki Shirakawa for discovering a method to create conductive polymers. Conductive polymers are organic polymers that are modified to conduct electricity and are used as anti-static material and in battery technologies.
Astronaut Bruce McCandless II became the first person to spacewalk untethered to a ship. He tested the manned maneuvering unit with Robert Stewart for the possibility of future extravehicular activities without the umbilical tether. This practice is extremely hazardous and is now only used if an emergency use only.
Kurchatov was the Soviet nuclear physicist who would lead the Soviet nuclear research program to produce the first Soviet atomic weapon, thermonuclear weapon, and the first atomic power plant. He was working on the technical problems involved in producing a chain reaction using uranium when the German invasion of Russia began and halted his researc...
Feoktistov is a Soviet cosmonaut/engineer who worked part of the team who designed Sputnik, Vostok, Voskhod, and Soyuz spacecraft. He would go on to head the design team which designed the Salyut and Mir space stations. He also worked on a design for an ion-powered spacecraft for a manned Mars mission.
Sager was an American geneticist who was a pioneer in cytoplasmic genetics where she demonstrated the existence of hereditary determinants other than nuclear genes. She later changed the focus of her career to the genetics of cancer tumors and suppressor genes. She worked on the study of the genetics of how cancer cells multiply to combat the mecha...
Euler was a Swedish physiologist and pharmacologist who shared the 1970 Nobel Prize in Medicine with Bernard Katz and Julius Axelrod for their work with neural transmitters. He was researching the role of noradrenaline in biological and neural tissues. He discovered it was produced and stored in nerve synaptic terminals.
Ferraris was an Italian physicist and electrical engineer known for his work on rotary magnetic fields. He published the design for his alternating current motor the same year Tesla gained a US patent for an AC motor. His motor used electromagnets at right angles and powered by alternating currents that were 90° out of phase to produce a revolving ...
Huggins was an English amateur astronomer and a pioneer of spectroscopy. He discovered dark-line spectra that occurs when light passes through a gas. He also found nebulae consisted of glowing gas.
Feb 7, 2011 · 1863: British chemist John Newlands organizes the known elements, listing them in a table determined by atomic weight, according to what he provisionally calls his “law of octaves.” It is not...
Feb 7, 2021 · British chemist John Newlands was the first to arrange the elements into a periodic table with increasing order of atomic masses. He found that every eight elements had similar properties and called this the law of octaves.
John Newlands was a British chemist who is known for his work on the Periodic Table. He proposed the Law of Octaves, which arranged elements into rows of seven, repeating their properties...
