.Hi bobbym,

The Answers : #5257 - Ernest Lawrence and #5258 - Percy Williams Bridgman.

The Answer #5257 is correct. Excellent, bobbym!

#5259. Name the American physicist and inventor; along with John Bardeen and Walter Houser Brattain, he co-invented the transistor, for which all three were awarded the 1956 Nobel Prize in Physics.

#5260. Name the Soviet physicist who made fundamental contributions to many areas of theoretical physics; his accomplishments include the independent co-discovery of the density matrix method in quantum mechanics (alongside John von Neumann), the quantum mechanical theory of diamagnetism, the theory of superfluidity, the theory of second-order phase transitions. He received the 1962 Nobel Prize in Physics for his development of a mathematical theory of superfluidity that accounts for the properties of liquid helium II at a temperature below 2.17 K (−270.98°C).

#5257. Name the pioneering American nuclear scientist, winner of the Nobel Prize for Physics in 1939 for his invention of the cyclotron. He is also known for his work on uranium-isotope separation for the Manhattan Project.

#5258. Name the American physicist who won the 1946 Nobel Prize in Physics for his work on the physics of high pressures. He also wrote extensively on the scientific method and on other aspects of the philosophy of science. In 1905, he began investigating the properties of matter under high pressure. A machinery malfunction led him to modify his pressure apparatus; the result was a new device enabling him to create pressures eventually exceeding 100,000 kgf/cm² (10 GPa; 100,000 atmospheres).

#5255. Name the English theoretical physicist who made fundamental contributions to the early development of both quantum mechanics and quantum electrodynamics. He shared the Nobel Prize in Physics for 1933 with Erwin Schrödinger, "for the discovery of new productive forms of atomic theory". He also did work that forms the basis of modern attempts to reconcile general relativity with quantum mechanics.

#5256. Name the American physicist who is best known for his discovery of the positron in 1932, an achievement for which he received the 1936 Nobel Prize in Physics, and of the muon in 1936.

#5253. Name the German theoretical physicist who originated quantum theory, which won him the Nobel Prize in Physics in 1918. He made many contributions to theoretical physics, but his fame rests primarily on his role as originator of the quantum theory. This theory revolutionized human understanding of atomic and subatomic processes, just as Albert Einstein’s theory of relativity revolutionized the understanding of space and time.

#5254. Name the German physicist, and Physics Nobel Prize laureate who in 1919, won the Nobel Prize in Physics for his "discovery of the Doppler effect in canal rays and the splitting of spectral lines in electric fields".

#5249. Name the (15 February 1874 – 5 January 1922) polar explorer who led three British expeditions to the Antarctic, and one of the principal figures of the period known as the Heroic Age of Antarctic Exploration. After the race to the South Pole ended in December 1911 with Roald Amundsen's conquest, he turned his attention to what he said was the one remaining great object of Antarctic journeying: the crossing of the continent from sea to sea, via the pole. To this end he made preparations for what became the Imperial Trans-Antarctic Expedition, 1914–17. Disaster struck this expedition when its ship, Endurance, became trapped in pack ice and was slowly crushed before the shore parties could be landed.
