Science Research (Presentation)

  1. 1. Rosalind Flsie Franklin <ul><li>Achievement / Introduction </li></ul><ul><li>Process </li></ul><ul><li>Lifespan </li></ul>
  2. 2. Achievement / Introduction <ul><li>When she was 15, she decided to become a scientist. </li></ul><ul><li>Her father wanted her to become a social worker. </li></ul><ul><li>Rosalind Flsie Franklin (July 25, 1920 – April 16, 1958) </li></ul><ul><li>English biophysicist and crystallographer who made important contributions to the understanding of the fine structures of DNA , viruses , coal and graphite . </li></ul><ul><li>Franklin is best known for her work on the </li></ul><ul><li>X-ray diffraction images of DNA. </li></ul>
  3. 3. Process <ul><li>1947 to 1950, she worked at the Laboratories Central (Services Chimiques de L'Etat) in Paris. </li></ul><ul><li>In 1951, she returned to England and worked in the lab at King's College in Cambridge. </li></ul><ul><li>It was there that she was given the responsibility for the DNA project and she worked somewhat awkwardly with Maurice Wilkins. </li></ul><ul><li>Rosalind almost cracked the DNA code, but Wilkins gave some of her DNA pictures to James Watson and Francis Crick, and they solved it. </li></ul><ul><li>Rosalind moved to a lab at Birkbeck College where she studied the tobacco mosaic virus and the polio virus. </li></ul>
  4. 4. Lifespan <ul><li>In 1956, Rosalind became sick with ovarian cancer. </li></ul><ul><li>Died on April 16, 1958 in England from the cancer. </li></ul>
  5. 5. James Watson <ul><li>- Achievement / Introduction </li></ul><ul><li>Process </li></ul><ul><li>Lifespan </li></ul>
  6. 6. Achievement / Introduction <ul><li>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. </li></ul><ul><li>Watson, Francis Crick, and Maurice Wilkins were awarded the 1962 Nobel Prize for Physiology or Medicine </li></ul><ul><li>For their discoveries concerning the molecular structure of nucleic acids. </li></ul>
  7. 7. Process <ul><li>James Watson became a Senior Research Fellow in Biology at the California Institute of Technology. </li></ul><ul><li>The following year he moved to Harvard University, where he became Professor of Biology, a post he held until 1976. </li></ul><ul><li>In 1968 Watson published his account of the DNA discovery, “ The Double Helix” . </li></ul><ul><li>The book became an international best-seller, but some in the scientific community were scandalized. </li></ul><ul><li>James Watson insisted that devotion to the truth was as essential in writing for the general public as it is in scientific research. </li></ul>
  8. 8. Lifespan <ul><li>Universities and governments around the world have honored James Watson with honorary degrees and decorations. </li></ul><ul><li>Apart from his many scientific papers and the best-selling Double Helix. </li></ul><ul><li>Watson's writings include: </li></ul><ul><li>- The DNA Story </li></ul><ul><li>- Molecular Biology of the Gene </li></ul><ul><li>-Molecular Biology of the Cell Recombinant DNA: A Short Course </li></ul>
  9. 9. Next Scientist <ul><li>John Dalton </li></ul><ul><li>Marie Curie </li></ul>
  10. 10. John Dalton <ul><li>Achievement / Introduction </li></ul><ul><li>- Process </li></ul><ul><li>Lifespan </li></ul>
  11. 11. Achievement / Introduction <ul><li>John Dalton (September 6, 1766 - July 27, 1844) </li></ul><ul><li>the English teacher (chemist, and physicist) </li></ul><ul><li>Best known for developing the ancient concept of atoms into a scientific theory that has become a foundation of modern chemistry. </li></ul><ul><li>A self-taught experimenter, he devised simple but effective apparatuses for his well-planned tests. </li></ul><ul><li>Although authors have emphasized the crudeness of his results, much of his data is remarkably accurate. </li></ul>
  12. 12. Process <ul><li>Around 1790, Dalton have considered taking up law or medicine, but his projects were not met with encouragement from his relatives. </li></ul><ul><li>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. </li></ul><ul><li>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. </li></ul>
  13. 13. Lifespan <ul><li>Died in Manchester in 1844 of paralysis. </li></ul><ul><li>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. </li></ul><ul><li>In May 1844, he had another stroke. </li></ul><ul><li>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. </li></ul><ul><li>Dalton was buried in Manchester in Ardwick cemetery (now a playing field) . </li></ul>
  14. 14. Marie Curie <ul><li>Achievement / Introduction </li></ul><ul><li>Process </li></ul><ul><li>Lifespan </li></ul>
  15. 15. Achievement / Introduction <ul><li>Marie Curie (November 7, 1867 – July 4, 1934) was a Polish-French physicist and chemist. </li></ul><ul><li>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. </li></ul>
  16. 16. Process <ul><li>In 1891 she went to Paris, France, to study science. </li></ul><ul><li>She obtained her higher degrees and conducted nearly all her scientific work there, and became a naturalized French citizen. </li></ul><ul><li>She founded the Curie Institutes in Paris, France, and in her home town, Warsaw. </li></ul>
  17. 17. Lifespan <ul><li>By 1934, Curie's health was failing rapidly. </li></ul><ul><li>The toll of heavy exposure to radiation was at last overpowering her impressive constitution. </li></ul><ul><li>On 4 July 1934 she succumbed to aplastic anemia, or leukemia, induced by radiation exposure. </li></ul><ul><li>In 1995, she was exhumed and reburied at the Panthéon in Paris </li></ul>
