Transcript

  • 1. Rosalind Flsie Franklin
    • Achievement / Introduction
    • Process
    • Lifespan
  • 2. Achievement / Introduction
    • When she was 15, she decided to become a scientist.
    • Her father wanted her to become a social worker.
    • Rosalind Flsie Franklin (July 25, 1920 – April 16, 1958)
    • English biophysicist and crystallographer who made important contributions to the understanding of the fine structures of DNA , viruses , coal and graphite .
    • Franklin is best known for her work on the
    • X-ray diffraction images of DNA.
  • 3. Process
    • 1947 to 1950, she worked at the Laboratories Central (Services Chimiques de L'Etat) in Paris.
    • In 1951, she returned to England and worked in the lab at King's College in Cambridge.
    • It was there that she was given the responsibility for the DNA project and she worked somewhat awkwardly with Maurice Wilkins.
    • Rosalind almost cracked the DNA code, but Wilkins gave some of her DNA pictures to James Watson and Francis Crick, and they solved it.
    • Rosalind moved to a lab at Birkbeck College where she studied the tobacco mosaic virus and the polio virus.
  • 4. Lifespan
    • In 1956, Rosalind became sick with ovarian cancer.
    • Died on April 16, 1958 in England from the cancer.
  • 5. James Watson
    • - Achievement / Introduction
    • Process
    • Lifespan
  • 6. Achievement / Introduction
    • James Dewey Watson (born: April 16, 1928) is an American molecular biologist, best known as one of the co-discoverers of the structure of the DNA molecule.
    • Watson, Francis Crick, and Maurice Wilkins were awarded the 1962 Nobel Prize for Physiology or Medicine
    • For their discoveries concerning the molecular structure of nucleic acids.
  • 7. Process
    • James Watson became a Senior Research Fellow in Biology at the California Institute of Technology.
    • The following year he moved to Harvard University, where he became Professor of Biology, a post he held until 1976.
    • In 1968 Watson published his account of the DNA discovery, “ The Double Helix” .
    • The book became an international best-seller, but some in the scientific community were scandalized.
    • James Watson insisted that devotion to the truth was as essential in writing for the general public as it is in scientific research.
  • 8. Lifespan
    • Universities and governments around the world have honored James Watson with honorary degrees and decorations.
    • Apart from his many scientific papers and the best-selling Double Helix.
    • Watson's writings include:
    • - The DNA Story
    • - Molecular Biology of the Gene
    • -Molecular Biology of the Cell Recombinant DNA: A Short Course
  • 9. Next Scientist
    • John Dalton
    • Marie Curie
  • 10. John Dalton
    • Achievement / Introduction
    • - Process
    • Lifespan
  • 11. Achievement / Introduction
    • John Dalton (September 6, 1766 - July 27, 1844)
    • the English teacher (chemist, and physicist)
    • Best known for developing the ancient concept of atoms into a scientific theory that has become a foundation of modern chemistry.
    • A self-taught experimenter, he devised simple but effective apparatuses for his well-planned tests.
    • Although authors have emphasized the crudeness of his results, much of his data is remarkably accurate.
  • 12. Process
    • Around 1790, Dalton have considered taking up law or medicine, but his projects were not met with encouragement from his relatives.
    • Mainly through John Gough, a blind philosopher to whom he owed much of his scientific knowledge, Dalton was appointed teacher of mathematics and natural philosophy at the Manchester Academy.
    • He remained in that position until the college's relocation to York in 1803, when he became a public and private teacher of mathematics and chemistry.
  • 13. Lifespan
    • Died in Manchester in 1844 of paralysis.
    • The first attack he suffered in 1837 and a second in 1838 left him with a speech impediment, though he remained able to make experiments.
    • In May 1844, he had another stroke.
    • On July 26 he recorded with trembling hand his last meteorological observation, and on the 27th he fell from his bed and was found lifeless by his attendant.
    • Dalton was buried in Manchester in Ardwick cemetery (now a playing field) .
  • 14. Marie Curie
    • Achievement / Introduction
    • Process
    • Lifespan
  • 15. Achievement / Introduction
    • Marie Curie (November 7, 1867 – July 4, 1934) was a Polish-French physicist and chemist.
    • A pioneer in the field of radioactivity, the first twice-honored Nobel laureate (and still today the only laureate in two different sciences) , and the first female professor at the Sorbonne.
  • 16. Process
    • In 1891 she went to Paris, France, to study science.
    • She obtained her higher degrees and conducted nearly all her scientific work there, and became a naturalized French citizen.
    • She founded the Curie Institutes in Paris, France, and in her home town, Warsaw.
  • 17. Lifespan
    • By 1934, Curie's health was failing rapidly.
    • The toll of heavy exposure to radiation was at last overpowering her impressive constitution.
    • On 4 July 1934 she succumbed to aplastic anemia, or leukemia, induced by radiation exposure.
    • In 1995, she was exhumed and reburied at the Panthéon in Paris
  • 18. The End Completed by: - millie; 15 (john dalton & marie curie) - shumei; 32 (john dalton & marie curie) - stephanie; 25 (james watson & rosalind flsie franklin) - tse lay; 28 (james watson & rosalind flsie franklin)
