French mathematician, physicist, and religious philosopher.

"Pascal was a mathematician of the first order. He helped create two major new areas of research. He wrote a significant treatise on the subject of projective geometry at the age of sixteen and corresponded with Pierre de Fermat from 1654 and later on probability theory, strongly influencing the development of modern economics and social science."

Born in India 1937.

"Pati has made pioneering contributions to the notion of a unification of elementary particles – quarks and leptons – and of their gauge forces force: weak, electromagnetic, and strong. His formulation, carried out in collaboration with Abdus Salam, of the original gauge theory of quark–lepton unification, and their resulting insight that violations of baryon and lepton numbers, especially those that would manifest in proton decay, are likely consequences of such a unification, provide cornerstones of modern particle physics today."

"Sir Rudolf Ernst Peierls, (June 5, 1907, Berlin – September 19, 1995, Oxford), was a German-born British physicist. Rudolph Peierls had a major role in Britain's nuclear program, but he also had a role in many modem sciences. His impact on Physics can probably be best described by his obituary in Physics Today: "Rudolph Peierls...a major player in the drama of the irruption of nuclear physics into world affairs...""

William Prout was born in Horton, Gloucestershire on January 15, 1785 and died in London on April 9, 1850.

"Prout contributed to the improvement of the barometer, and the Royal Society of London adopted his design as a national standard.

Prout wrote the eighth Bridgewater Treatise, Chemistry, Meteorology, and the Function of Digestion, considered with reference to Natural Theology.

The unit of nuclear binding energy, Prout, equal to 1/12 binding energy of the deuteron, or 185.5 keV is named after William Prout."

"Pupin is best known for his landmark theory of modern electrical filters and for his numerous patents, including a means of greatly extending the range of long-distance telephone communication by placing loading coils (of wire) at predetermined intervals along the transmitting wire (known as pupinization)."

"He conducted extensive studies of soap films and formulated Plateau's laws which describe the structures formed by such films in foams.

Fascinated by the persistence of luminous impressions on the retina, he performed an experiment in which he gazed directly into the sun for 25 seconds. Consequently, he lost his eyesight later in his life. He died in Ghent."

"Like the Pythagoreans Hicetas and Ecphantus, Heraclides proposed that the apparent daily motion of the stars was created by the rotation of the Earth on its axis once a day. According to a late tradition, he also believed that Venus and Mercury revolve around the Sun. This would mean that he anticipated the Tychonic system, an essentially geocentric model with heliocentric aspects."

"John Henry Poynting (September 9, 1852 – March 30, 1914) was an English physicist. He was a professor of physics at Mason Science College (now the University of Birmingham) from 1880 until his death.

He was the developer and eponym of the Poynting vector, which describes the direction and magnitude of electromagnetic energy flow and is used in the Poynting theorem, a statement about energy conservation for electric and magnetic fields. This work was first published in 1884. He performed a measurement of Newton's gravitational constant by innovative means during 1893. In 1903 he was the first to realise that the Sun's radiation can draw in small particles towards it. It was later coined the Poynting-Robertson effect.

In the year 1884 he analysed the futures exchange prices of commodities using statistical mathematics."

"As a result of experiments into what he called cold light Pulyui is reputed to have developed an X-ray emitting device as early as 1881. Pulyui reputedly first demonstrated an X-ray photograph of a 13-year-old boy's broken arm and an X-ray photograph of his daughter's hand with a pin lying under it. The device became known as the Pulyui lamp and was mass-produced for a period. Reputedly, Pulyui personally presented one to Wilhelm Conrad Röntgen who went on to be credited as the major developer of the technology."
