PRESENTATION OUTLINE
DEMOCRITUS
- (460-370)BC
- After his major discoveries,he is consider the ''Father of modern sience''
- Democritus was known as '' The laughing philiosohere
Aristotle
- (384-322)BC
- The majority of Aristotle’s original work has been lost through the passage of time but around one third of it still remains to this day.
- Famous Aristotle quotes include: “Time crumbles things; everything grows old under the power of Time and is forgotten through the lapse of Time.”
antoine lavoisier
- (1743-1794)
- After having a formal education in law and literature, Lavoisier studied science under some of the most well-known figures of the day. He helped develop the first geological map of France and the main water supply of Paris in 1769 at a young age of 25. This earned him a membership of the Royal Academy of Sciences in 1768. The same year he managed to purchase a part-share in the ‘tax farm’, a private tax collection agency.
JOSEPH LOUIS PROUST
- (1754-1826)
- Joseph L. Proust was born on September 26, 1754 in Angers, France. His father served as an apothecary in Angers. Joseph studied chemistry in his father’s shop and later came to Paris where he gained the appointment of apothecary in chief to the Salpetriere [1][dead link]. He also taught chemistry with Pilâtre de Rozier, a famous aeronaut.
john dalton
- (1766-1844)
- Chemist John Dalton was born September 6, 1766, in Eaglesfield, England. During his early career, he identified the hereditary nature of red-green color blindness. In 1803 he revealed the concept of Dalton’s Law of Partial Pressures. Also in the 1800s, he was the first scientist to explain the behavior of atoms in terms of the measurement of weight. Dalton died July 26, 1844 in Manchester, England.
MICHAEL FARADAY
- (1791-1867)
- In 1831, using his "induction ring", Michael Faraday made one of his greatest discoveries - electromagnetic induction: the "induction" or generation of electricity in a wire by means of the electromagnetic effect of a current in another wire. The induction ring was the first electric transformer. In a second series of experiments in September he discovered magneto-electric induction: the production of a steady electric current. To do this, Faraday attached two wires through a sliding contact to a copper disc. By rotating the disc between the poles of a horseshoe magnet he obtained a continuous direct current. This was the first generator. From his experiments came devices that led to the modern electric motor, generator and transformer.
HENRI BECQUEREL
- (1852-1908)
- Born on December 15, 1852, in Paris, France, to a clan of scientists, Henri Becquerel worked in engineering and academia, making pioneering discoveries in phosphorescence and what would be coined as natural radioactivity. He earned the Nobel Prize in Physics in 1903, sharing the award with the Curies. He also became life secretary of the French Academy of Sciences. He died on August 25, 1908.
J.J. THOMSON
- (1856-1940)
- Sir Joseph John Thomson, more commonly known as J. J. Thomson, was an English physicist who stormed the world of nuclear physics with his 1897 discovery of the electron, as well as isotopes. He is also credited with the invention of the mass spectrometer. He received the Nobel Prize for Physics in 1906 and was knighted two years later in 1908.
MAX PLANCK
- (1858-1947)
- Planck got honorary doctorates from the universities of Frankfurt, Rostock, Athens, Cambridge, Berlin (TH), Graz, London, Munich (TH), and Glasgow.
- In 1918Planck was also given the Nobel Prize in Physics.
marie & pierre curie
- (1859-1906)
- Pierre & Marie Curie were both extraordinary scientists. They married in 1895 and were awarded the Nobel Prize in Physics in 1903 for their joint research on radiation. Pierre Curie died on April the 19th 1906 in a street accident, devastating Marie after the two had become so close. Some have speculated that he was weakened by radiation exposure but this has never been proven. Marie Curie’s eventual death in 1934 however was almost certainly due to an over exposure of radiation over a long period of time. Read on for interesting facts, quotes and information about Marie & Pierre Curie.
ROBERT MILIKAN
- (1868-1953)
- American physicist Robert A. Milikan's achievements began when he was the first to received a Ph.D from the physics department at Columbia University. He went on to win the Nobel Prize for physics for his work on the photoelectric effect and measuring the charge of the electron. He also was able to obtain the exact exact value of Planck's constant.
ernest rutherford
- (1871-1937)
- Affiliation at the time of the award: Victoria University, Manchester, United Kingdom
- Prize motivation: "for his investigations into the disintegration of the elements, and the chemistry of radioactive substances"
ALBERT EINSTEIN
- (1879-1955)
- Affiliation at the time of the award: Kaiser-Wilhelm-Institut (now Max-Planck-Institut) für Physik, Berlin, Germany
- Prize motivation: "for his services to Theoretical Physics, and especially for his discovery of the law of the photoelectric effect"
NEILS BOHR
- (1885-1962)
- His full name was Neils Henrik David Bohr. He was a member of the college soccer team and always wished that he be able to play the game as well as his brother. The latter eventually went on to play with the 1908 Olympic Danish team who won the silver.
- Bohr worked very closely with Albert Einstein in 1938 and helped carry-out atomic research;
james chadwick
- (1891-1971)
- He attended Manchester High School prior to entering Manchester University in 1908; he graduated from the Honours School of Physics in 1911 and spent the next two years under Professor (later Lord) Rutherford in the Physical Laboratory in Manchester, where he worked on various radioactivity problems, gaining his M.Sc. degree in 1913.
