Aristotle (384 BC-323 BC) Greece :

With Plato, Kant, and perhaps a few others, Aristotle is one of the greatest philosophers of all time. More than any other philosopher, Aristotle's writings cover a vast range of human knowledge. For example, he invented logic, created biology as a science, defined the study of poetic tragedy, and produced the definitive work on eudemonic ethics. Dante gave him pride of place amongst all thinkers, calling him 'the master of those who know'.

Alexander Graham Bell (1847 – 1922) Scotland :

He is the inventor of the telephone and the metal detector. He was an eminent scientist, inventor, engineer and innovator who is credited with inventing the first practical telephone. Many other inventions marked Bell's later life, including groundbreaking work in optical, telecommunications, hydrofoils and aeronautics. In 1888, Alexander Graham Bell became one of the founding members of the National Geographic Society.

Sir William Henry Bragg (1862-1942) England :

The Nobel Prize in Physics 1915 was awarded jointly to Sir William Henry Bragg and William Lawrence Bragg "for their services in the analysis of crystal structure by means of X-rays" The work of Bragg and his son Lawrence in 1913-1914 founded a new branch of science of the greatest importance and significance, the analysis of crystal structure by means of X-rays. If the fundamental discovery of the wave aspect of X-rays, as evidenced by their diffraction in crystals, was due to von Laue and his collaborators, it is equally true that the use of X-rays as an instrument for the systematic revelation of the way in which crystals are built was entirely due to the Braggs. This was recognized by the award of the Nobel Prize jointly to father and son in 1915.

William Lawrence Bragg (1890-1971) Australia :

Sir William Lawrence Bragg was an Australian- born British physicist and X-ray crystallographer, discoverer (1912) of the Bragg law of X-ray diffraction, which is basic for the determination of crystal structure. He was joint winner (with his father, Sir William Bragg) of the Nobel Prize for Physics in 1915. He was knighted in 1941. To date, Lawrence Bragg is the youngest Nobel Laureate. He was the director of the Cavendish Laboratory, Cambridge, when the epochal discovery of the structure of DNA was made by James D. Watson and Francis Crick in February 1953. Together with his father, he has published various scientific papers on crystal structure after their joint publication of 1915: The Crystalline State (1934), Electricity (1936), and Atomic Structure of Minerals (1937).

Nicolaus Copernicus (1473 – 24 May 1543) Italy :

Copernicus was a Renaissance astronomer and the first person to formulate a comprehensive heliocentric cosmology which displaced the Earth from the center of the universe. His theorized that the Sun was the fixed point around which the motion of the planets takes place. The Earth rotates around its axis once in a day and slow alterations in the direction of this axis cause the precession of the equinoxes

Leonardo da Vinci (1452 – 1519) Italy :

Leonardo da vinci Italian polymath: painter, sculptor, architect, musician,scientist, mathematician, engineer, inventor, anatomist, geologist, cartographer, botanist and writer

Hideki Yukawa (1907-1981) :

The Nobel Prize in Physics 1949 was awarded to Hideki Yukawa "for his prediction of the existence of mesons on the basis of theoretical work on nuclear forces". In 1935 he published his theory of mesons, which explained the interaction between protons and neutrons, and was a major influence on research into elementary particles Yukawa also worked on the theory of K-capture, in which a low energy electron is absorbed by the nucleus, after its initial prediction by G. C. Wick.

"There are three types of people in this world: those who make things happen, those who watch things happen and those who wonder what happened. We all have a choice. You can decide which type of person you want to be. I have always chosen to be in the first group."
