Species. Darwin has been described as one of the most influential
figures in human history.
Dr. Homi Bhabha - Homi
Jehangir Bhabha was an Indian nuclear physicist, founding director,
and professor of physics at the Tata Institute of Fundamental
Research. Colloquially known as "father of the Indian nuclear
programme".
Jagdish Chandra Bose -
Jagadish Chandra Bose, was a polymath, physicist, biologist,
biophysicist, botanist and archaeologist, as well as an early writer
of science fiction. He also invented the crescograph. He also
pioneered the investigation of radio and microwave optics, made very
significant contributions to plant science.
Dr. C. V. Raman -
Chandrasekhara Venkata Raman was an Indian physicist, who carried
out ground-breaking work in the field of light scattering, what now
is called the 'Raman Effect', which earned him the 1930 Nobel Prize
for Physics. In 1954, India honoured him with its highest civilian
award, the Bharat Ratna.
Marie Curie - Marie Curie
was a Polish and naturalised-French physicist, chemist and feminist
who conducted pioneering research on radioactivity. She created a
theory of radioactivity, found different ways for separating
radioactive isotopes and discovered two new elements, radium and
polonium. She was also the first woman to win a Nobel Prize as well
as the first person to win two Nobel Prizes.
William Harvey - William
Harvey was an English physician who made seminal contributions in
anatomy and physiology. He was the first known to describe
completely and in detail the systemic circulation and properties of
blood being pumped to the brain and body by the heart i.e.
circulation of blood.
Nicolaus Copernicus -
Nicolaus Copernicus was a Renaissance mathematician and astronomer
who formulated a model of the universe that placed the Sun rather
than the Earth at the center of the universe. The publication of
this model in his book De revolutionibus orbium coelestium. His
formula of how the sun, rather than the earth, is at the centre of
the solar system, is still one of the most important scientific
hypotheses in history. It was the beginning of modern astronomy.
Sir Humphry Davy - Humphry
Davy, was a Cornish chemist and inventor, who is best remembered
today for his discoveries of several alkali and alkaline earth
metals, as well as contributions to the discoveries of the elemental
nature of chlorine and iodine. In 1815, he invented the miner's lamp
to be used by miners in mines.
Alexander Fleming - Sir
Alexander Fleming was a Scottish biologist, pharmacologist and
botanist. He is best known for discovering the antibiotic substance
penicillin in 1928. He won a Nobel Prize in Physiology or Medicine
in 1945. His discovery of penicillin had changed the world of modern
medicine by introducing the age of useful antibiotics; penicillin
has saved, and is still saving, millions of people around the world.
Wilbur Wright & Orville
Wright – The Wright brothers, Orville and Wilbur, were two
American brothers, inventors and aviation pioneers who are credited
with inventing, building and flying the world's first successful
airplane. They designed, built and flew the first controlled,
powered, heavier-than-air airplane on December 17, 1903.
Samuel Morse - Samuel Morse
was an American painter and inventor. After having established his
reputation as a portrait painter, Morse contributed to the invention
of a single-wire telegraph system based on European telegraphs. He
was also a co-developer of the Morse code and helped to develop the
commercial use of telegraphy.
Louis Pasteur - Louis
Pasteur was a French microbiologist and chemist.He is best known for
his experiments supporting the Germ theory of disease and he is also
known for his vaccinations, most notably the first vaccine against
rabies. He made many discoveries in the field of chemistry,
including the asymmetry of crystals. He is also well known for his
way of keeping milk and wine from going sour for longer periods of
time. That process is called pasteurization.
