Galileo Galilei

1604 - 1612

Through his use of mathematics and physical experimentation, Galileo was able to formulate the Law of Fall in 1604, which is related to the Law of Inertia which he first formulated in 1612

Johannes Keepler

1609 - 1619

Johannes Kepler published his first two laws in 1609, having found them by analyzing the astronomical observations of Tycho Brahe.[2] Kepler discovered his third law many years later, and it was published in 1619.[2]

Charles Darwin


Charles Darwin believed that all life descended from ancestor's.

Neils Bohr


Niels Bohr proposed the Bohr Model of the Atom in 1915.

Issac Newton


For years, Newton and many other scientists before he had wondered what kept the moon and planets in orbit. Newton's work in this area, led not only to an understanding of gravity which is the attraction of bodies toward the center of the earth, but to theories on how an artificial satellite might be sent into orbit. The first artificial satellite, Sputnik 1, was finally launched in the year 1957, but only with the use of Newton's theories.

5 important medical people

Elizabeth Blackwell


Elizabeth Blackwell, an important figure in both the history of medicine and the women’s rights movement, achieved a historic triumph on Jan. 23, 1849, when she was awarded her Medical Degree by Geneva Medical College in New York. With that distinction she became the first woman doctor in U.S. history. She would go on to practice medicine, open the New York Infirmary for Indigent Women and Children, establish women’s medical schools in both England and the U.S., and write about the rights of women to be educated and to enter the medical profession.

Rudolf Virchow


Rudolf Virchow was a German pathologist, anthropologist and statesman, widely credited for his advancements in public health. Known as the "father of pathology," his scientific contribution of cell theory explained the effects of disease on the body. He also developed a standard method of autopsy procedure. In 1869 he founded a society which greatly intensifying German archaeological research.

Alexander Fleming

1881 - 1955

Born in Scotland in 1881, Alexander Fleming served in World War I in the Royal Army Medical Corps, where he saw infected wounds take the lives of many soldiers. After the war, while thinking he had accidentally discovered a new enzyme in his lab, Fleming discovered antibiotics. In 1945, he was co-awarded the Nobel Prize in Physiology or Medicine. Fleming died in London in 1955.

Daniel Hale Williams

He was also the first physician to successfully complete open-heart surgery on a patient. Williams later became chief surgeon of the Freedmen’s Hospital.

5 important medical events

Discovery of pulmonary ciculation


In 1242, the Arabian physician, Ibn al-Nafis, became the first person to accurately describe the process of pulmonary circulation, for which he is sometimes considered the father of circulatory physiology. Although some of the earliest people already had the thought of the system, it was in the year 1628 that William Harvey announced that the discovery of the human circulatory system was his. He performed several tests and wrote an influential book, and these convinced the medical world to believe in the genuineness of the discovery. Harvey was not able to identify the capillary system connecting arteries and veins; these were later described by Marcello Malpighi. Also important to mention, Austrian biologist Karl Landsteiner and his group discovered four blood groups and develop a system of classification. Knowledge of the different blood types is crucial to performing safe blood transfusions, now a common practice.

Germ Theory


Germ theory (discovered by French chemist Louis Pasteur) allowed our scientist to find the major causes behind disease, and created a whole new understanding on why cleanliness was important, as opposed to the old practice of surrounding oneself with bad smells to ward off bad influences. At that time, the origin of diseases such as cholera, anthrax and rabies was a mystery. The discovery of germ theory helped bring the knowledge of the importance of sanitation, and is one of the biggest factors in extending human life by prevention of disease.

Discovery of DNA


Frederick Hopkins and a few other scientists discover (in the early 1900′s) that some diseases are caused by deficiencies of certain nutrients, later called vitamins. Through feeding experiments with laboratory animals, Hopkins concludes that these “accessory food factors” are essential to health.

Discovered Insulin


Frederick Banting and his colleagues discover the hormone insulin (1920′s), which helps balance blood sugar levels in diabetes patients and allows them to live normal lives. Before insulin, diabetes meant a slow and certain death. Insulin stops the use of fat as an energy source by inhibiting the release of glucagon. When insulin is absent, glucose is not taken up by body cells and the body begins to use fat as an energy source or gluconeogenesis. For example, by transfer of lipids from adipose tissue to the liver for mobilization as an energy source.

Discorvery of AIDS and HIV


Competing scientists Robert Gallo and Luc Montagnier separately discover a new retrovirus later dubbed HIV (human immunodeficiency virus), and identify it as the causative agent of AIDS (acquired immunodeficiency syndrome) – 1980′s.
