Archaeologists now believe that he was not first to invent the diatonic scale: If the energy during its propagation remained always attached to some material substratum, this matter would carry the light along with it and Fizeau has shown, at least for the air, that there is nothing of the kind.

He was among the very few ancient scholars who realized the Earth rotated daily on an axis; claims that he also espoused heliocentric orbits are controversial, but may be confirmed by the writings of al-Biruni. It therefore becomes useless.

I'm sure I've overlooked great mathematicians who obviously belong on this list. I then found out what demonstrate means, and went back to my law studies. Edison arranged for leading scientists to serve with him on the consulting board and also made available to the government the facilities of his laboratory.

The geocentric models couldn't explain the observed changes in the brightness of Mars or Venus, but it was the phases of Venus, discovered by Galileo after the invention of the telescope, that finally led to general acceptance of heliocentrism.

Referring to this system, Gauss was later to exclaim "To what heights would science now be raised if Archimedes had made that discovery! His greatest contribution, perhaps, was the incandescent lamp — the germ from which sprouted the great power utility systems of our day… Although his formal education stopped at the age of 12, his whole life was consumed by a passion for self-education, and he was a moving force behind the establishment of a great scientific journal.

When he added sound, he called it the kinetophone, which he introduced commercially inor 13 years before Hollywood adopted that means of improving motion picture entertainment.

But his teachings covered a very wide gamut and dominated the development of ancient science. Nicole Oresme and Nicholas of Cusa were pre-Copernican thinkers who wrote on both the geocentric question and the possibility of other worlds.

In mathematics, he was first to apply the Law of Sines to astronomy, geodesy, and cartography; anticipated the notion of polar coordinates; invented the azimuthal equidistant map projection in common use today, as well as a polyconic method now called the Nicolosi Globular Projection; found trigonometric solutions to polynomial equations; did geometric constructions including angle trisection; and wrote on arithmetic, algebra, and combinatorics as well as plane and spherical trigonometry and geometry.

In late Julyhe went to England for about six weeks at the personal invitation of British naval officer Commander Oliver Locker-Lampsonwho had become friends with Einstein in the preceding years. Eudoxus also introduced an Axiom of Continuity; he was a pioneer in solid geometry; and he developed his own solution to the Delian cube-doubling problem.

Tusi is most famous for his mathematics. Liu Hui ca China Liu Hui made major improvements to Chang's influential textbook Nine Chapters, making him among the most important of Chinese mathematicians ever.

In them, he successfully applied the results of their research to the problem of the motion of three bodies and studied in detail the behavior of solutions frequency, stability, asymptotic, and so on. And the notebooks in which he recorded the progress of thousands of experiments are still being gleaned of unused material.

He is less famous in part because he lived in a remote part of the Islamic empire. There would be time enough to think of taking it easy when he reachedhe said.

When he was seven years old, his family moved again; this time to Port Huron, Michigan. He produced a new proof of Archimedes' famous formula for the area of a parabolic section.

While many of his discoveries in geometry, plane and spherical trigonometry, and analysis parabola quadrature, trigonometric law, principle of lever duplicated work by Archimedes and Pappus, Thabit's list of novel achievements is impressive.

He introduced the Hindu decimal system to the Islamic world and Europe; invented the horary quadrant; improved the sundial; developed trigonometry tables; and improved on Ptolemy's astronomy and geography. His notation, clumsy as it was, was used for many centuries.

While Pythagoras had been horrified by the discovery of irrational numbers, Eudoxus is famous for incorporating them into arithmetic. Like Archimedes, he was able to calculate the area of an ellipse, and to calculate the volume of a paraboloid.

I must confess that the degree of their brutality and cowardice came as something of a surprise. Eudoxus has been quoted as saying "Willingly would I burn to death like Phaeton, were this the price for reaching the sun and learning its shape, its size and its substance.

Its humble size and simple design serve as a constant reminder that in America, a humble beginning does not hamper the rise to success. Although Archimedes didn't develop differentiation integration's inverseMichel Chasles credits him along with Kepler, Cavalieri, and Fermat, who all lived more than 18 centuries later as one of the four who developed calculus before Newton and Leibniz.

Another of Leonardo's noteworthy achievements was proving that the roots of a certain cubic equation could not have any of the constructible forms Euclid had outlined in Book 10 of his Elements.

He was considered one of the brightest of Greek mathematicians, and is the central character in two of Plato's Dialogs.

The Greeks borrowed from Babylonian mathematics, which was the most advanced of any before the Greeks; but there is no ancient Babylonian mathematician whose name is known.

It was this, rather than just the happenstance of planetary orbits, that eventually most outraged the Roman Church As well as being an original thinker, Thabit was a key translator of ancient Greek writings; he translated Archimedes' otherwise-lost Book of Lemmas and applied one of its methods to construct a regular heptagon.

Recently it has been shown that the magnificent Mechanical Problems attributed to pseudo- Aristotle were probably actually written by Archytas, making him one of the greatest mathematicians of antiquity.

The smallness of size, then, was no casual matter, but was intended to bring about, and did bring about, a result which the rod could never produce, and so converted failure into success.

On his return to Europe he was the guest of the British statesman and philosopher Viscount Haldane in London, where he met several renowned scientific, intellectual and political figures, and delivered a lecture at King's College London.

Aryabhata made several important discoveries in astronomy, e. Hippocrates also did work in algebra and rudimentary analysis. Rabindranath Tagore was born on May 7, in a wealthy Brahmin family in Calcutta. Pappus stated, but did not fully solve, the Problem of Pappus which, given an arbitrary collection of lines in the plane, asks for the locus of points whose distances to the lines have a certain relationship.Here is a brief biography and history of Rabindranath Tagore.

Read information on life of Indian Writer Rabindra Nath Tagore. Albert Einstein was born in Ulm, in the Kingdom of Württemberg in the German Empire, on 14 March His parents were Hermann Einstein, a salesman and engineer, and Pauline samoilo15.comthe family moved to Munich, where Einstein's father and his uncle Jakob founded Elektrotechnische Fabrik J.

Einstein & Cie, a company that manufactured electrical equipment based on direct current. Besides several other achievements Hawking has written several famous books innumerable research papers, articles, including a best selling book, A Brief History of Time.

The Hundred Greatest Mathematicians of the Past. This is the long page, with list and biographies. (Click here for just the List, with links to the samoilo15.com Click here for a. Albert Einstein was working as a patent clerk in Germany in when he developed his famous Theory of Relativity (E=mc2).

The theory simply states that the speed of light (constant, c) is the fastest speed in the universe and relates energy (E) and mass (M). Albert Einstein: a short biography Albert Einstein is probably the world’s most famous scientist but how much about him do you really know? Here is a short biography of the father of quantum theory.
