Archimedes - Archimedes was
an Ancient Greek mathematician, physicist, engineer, inventor and
astronomer. He developed the "Principle of Floatation". On
Floating Bodies Archimedes stated "When a body is wholly or
partially immersed in a fluid there is an upthrust which is equal to
the weight of fluid displaced". This is Principle of Floatation
also known as Archimedes Principle.
Albert Einstein - Albert
Einstein was a German-born theoretical physicist who developed
the general theory of relativity, one of the two pillars of modern
physics. Einstein is well known for his theories about light,
matter, gravity, space and time. His most well known equation is E =
mc2 . It means that energy and mass are different forms
of the same thing. His theories of special and general relativity
are of great importance to many branches of physics and astronomy.
He received the Nobel Prize in Physics in 1921.
Sir Issac Newton – Sir
Isaac Newton was an English physicist and mathematician. He is
famous for his work on the laws of motion, optics, gravity and
calculus. Sir Isaac Newton was the first to discover the laws of
gravitation and the laws of motion. Newton built the first practical
reflecting telescope and developed a theory of colour based on the
observation that a prism decomposes white light into the many
colours of the visible spectrum.
Galileo Galilei - Galileo
Galilei was an Italian astronomer, physicist, engineer, philosopher,
and mathematician who played a major role in the scientific
revolution. Galileo has been called the "father of
observational astronomy",the "father of modern physics"
and the "father of science".
Edmond Halley – Edmond
Halley, was an English astronomer, geophysicist, mathematician,
meteorologist and physicist who is best known for computing the
orbit of the Halley's Comet. Halley spent most of his time on lunar
observations.
Thomas Edison - Thomas Alva
Edison was an American inventor and businessman. He developed many
devices that greatly influenced life around the world, including the
phonograph (later known as grahamophone), the motion picture camera
and the long-lasting, practical electric light bulb. Edison was a
prolific inventor, holding 1,093 US patents in his name, as well as
many patents in the United Kingdom, France and Germany.
James Watt - James Watt was
a Scottish inventor, mechanical engineer, and chemist whose Watt
steam engine, an improvement of the Newcomen steam engine, was
fundamental to the changes brought by the Industrial Revolution in
both his native Great Britain and the rest of the world. He also
developed the concept of horsepower and the SI unit of power, the
watt, was named after him.
Alexander Graham Bell -
Alexander Graham Bell was a Scottish-born scientist, inventor,
engineer and innovator who is credited with patenting the first
practical telephone in 1876. Bell's later life, included
groundbreaking work in optical telecommunications, hydrofoils and
aeronautics. He is also credited with developing one of the early
versions of a metal detector in 1881.
Benjamin Franklin -
Benjamin Franklin was an American statesman and scientist. Franklin
was a scientist who studied experiments in an effort to improve or
correct them. One of his greatest contributions was in the theory of
electricity. Most people see Franklin as one of history's greatest
inventors. He invented the lightning rod, bifocals and the Franklin
stove, among other things.
Alessandro Volta -
Alessandro Volta was an Italian physicist, chemist and a pioneer of
electricity and power, who is credited as the inventor of the
electrical battery and the discoverer of methane. The SI unit of
electric potential is named in his honour as the volt.
Conrad Roentgen - Conrad
Rontgen was a German engineer and physicist, who, on 8 November
1895, produced & detected electromagnetic radiation in a
wavelength range known as X-rays or Röntgen rays, an achievement
that earned him the first Nobel Prize in Physics in 1901.
Edward Jenner - Edward
Jenner, was an English physician and scientist who was the pioneer
of smallpox vaccine, the world's first vaccine. He is often called
"the father of immunology", and his work is said to have
"saved more lives than the work of any other human".
