He was an American physicist and deputy administrator of NASA for 7 years who studied the aerodynamics of high speed. He headed the National Defence Research Committee during WWII. It developed the first successful US missile, the Bat radar-homing missile.

He was a German Physicist and a satirical writer, who researched a wide variety of fields such as, metrology, chemistry, mathematics, and astronomy. He constructed use electrophorus and discovered the basic principle of modern xerographic copying in 1777. He reproduced images that are still called “Lichtenberg figures”. He is also known for his aphorisms and his ridicule of romantic and metaphysical excesses.

He was a German astronomer who was the first to observe the planet Neptune. The existence of Neptune had been predicted in the calculations of Leverrier. Galle also discovered 3 comets while working at the Berlin Observatory. He discovered the inner C ring of Saturn while assisting Johann Franz Encke. He also gave the idea to use asteroids for the determination of solar parallax.

He was a German-American physicist who discovered nearly 1000 superconducting materials. He completed his Ph.D. in 1943 in Germany and went to the US to work at MIT. The low-temperature physics was started by him at the University of Chicago. He founded the institute University of Chicago, for the study of matter. He showed the properties of superconductivity, ferroelectricity, and ferromagnetism to be common occurrences in nature. He was able to find new examples of materials because of the relationships he could see in the periodic table.

He was an English physicist who worked on x-ray scattering. For his work, he was awarded the Nobel Prize for Physics in 1917. His techniques are used to investigate the atomic structures. He also showed that the scattering of X-rays by a gas depends on the molecular weight of the gas in 1903. His experiments showed that X-rays are electromagnetic radiation just like light. Later he also discovered that each element has its own x-ray spectrum.

He was an American astronaut who drove a wheeled vehicle on the moon on 31st July 1971. His crew was Neil Armstrong in Gemini 8, which was launched on 16 March 1966. They conducted the first docking in space. He flew on the Apollo 9 mission that was launched on 3 March 1969 for a 10 day Earth orbit test of the first complete set of Apollo hardware. He was in command of the Apollo 15 mission which made the fourth lunar landing. He became the seventh person to walk on the moon.

He was a Hungarian-British physicist who invented holography. It is a system of lenses with three-dimensional photography that has many applications. For this invention, he was awarded the Nobel Prize for Physics in 1971. The invention of holography was not possible until the invention of the laser in 1960 because the conventional filtered light sources had limitations of either too little light or too diffuse. His area of research was also on a high-speed oscilloscope, television, physical optics, and communication theory. He held more than a hundred patents.

He was a German Hungarian astronomer and the director of the observatory near Gotha. The first Congress of astronomy is organized by him with Joseph Lalande. He formed a group of 24 astronomers to track down the missing planet between the orbit of Mars and Jupiter in the last years of the 18th century. They discovered the asteroid belt while searching for the missing planet. He edited 28 volumes of Monatliche Korrespondenz zur Beforderung der Erd-und Himmelskunde.

He was a Scottish geologist who invented that the geological processes examined in the present time explain the formation of older rocks. He initiated the principle of uniformitarianism in his Theory of the Earth in 1985. He was the founder of modern psychology who replaced the belief that the earth’s crust was formed by a biblical flood. Institute introduced the understanding that sedimentary rocks are formed by the action of great heat beneath the earth’s crust.

He was an English nuclear scientist who was one of 12 volunteers that were injected with plutonium between 1992 to 1998. He volunteered to ingest a minute amount of plutonium as a part of European research. This research was done to track plutonium in the body’s metabolism. At the age of 73, he again volunteered to inhale plutonium to help for further study. He was one of the first Western scientists to visit Chernobyl after the explosion in 1986.
