Was born in February 19, 1473 in Frauenburg. He was a polish astronomer who proposed that the planets have the Sun as the fixed point to which their motions are to be referred. That the earth is a planet which besides orbiting the Sun annually, it also turns once daily on its axis.
-
Was a Italian philosopher, astronomer, and mathematician who made fundamental contributions to the sciences of motion, astronomy, and strength of materials and to the development of the scientific method.
-
He was an english mathematician, physicist, astronomer, alchemist, and natural philosopher who is generally regarded as one of the greatest scientists and mathematicians in history.
-
Daniel was the earliest writer who attempted to formulate kinetic theory of gases, He applied this idea to Boyle's law.
-
He was a physicist and was the founder of the atomic theroy. John Dalton once made this famous quote on his work concerning the atom, “ We might as well attempt to introduce a new planet into the solar system, or to annihilate one already in existence, as to create or destroy a particle of hydrogen.”
-
On the evening of November 8, 1895, he found that, if the discharge tube in enclosed in a sealed, thick black carton to exclude all light, and if he worked in a dark room, a paper plate covered on one side with barium platinocyanide placed in the path of the rays became fluorescent even when it was as far as two metres from the discharge tube.
-
Becquerel's earliest work was concerned with the plane polarization of light, with the phenomenon of phosphorescence and with the absorption of light by crystal (his doctorate thesis.)
-
Curie developed methods for the separation of radium from radioactive residues in good amounts to allow for its characterization, and the careful study of its properties.
-
As a scientist, Millikan made numerous momentous discoveries, chiefly in the fields of electricity, optics, and molecular physics. His earliest major success was the accurate determination of the charge carried by an electron, using the elegant "falling- drop method".
-
Rutherford's first reaserches, in new zealand, were concerned with the magnetic properties of iron exposed to high-frequency oscillations and his thesis was entitled Magnetiztion of iron by high-fequency discharges.
-
Born in Copenhagen. He carried out theoretical piece of a work on the absorption of alpha rays which was published in the Philosophical magazine in 1913.
-
Was a german physicist. He was an early investigator of discharge tubes, the discoverer of anode rays, and is sometimes credited with the discovery of the proton.
-
Was an Austrian theoretical physicist who achieved fame for his contributions to quantum mechanics, especially the schrodinger equation.
-
Was born in England. In 1932 Chadwick made a discovery in nuclear science. He proved the existence of neutrons, that elementary particles devoid of any electrical charge.
-
In 1941 Werner was professor of physics at the university of Berlin and director of the Kaiser Whilhelm institute of physics. At the end of WWII Werner and other German physicists were taken by american troops and sent to England
-
Was a german theoretical physicist who pioneered development in atomic and quantum physics, and also educated and groomed a large number of students for the new era of theoretical physics.
-
James is an american moleculer biologist, who is best known as one of the co-discoverers of the structure of DNA with Francis Crick, in 1953.
-
Was an italian physicist particularly remembered for his work on the development of the first nuclear reactor, and for his contributions to the development of quantum theory, nuclear and particle physics and statistical mechanics.
-
Was a Jesuit mathematician and astronomer. He was born in Ragusa, Croatia on May 18, 1711 and died in Milan, Italy in February 13, 1787.
-
While he was in strassburg in 1883, he privately built a prototype of the induction motor and ran it successfully.
