James Hutton (3 Jun 1726 - 26 Mar 1797)
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.
Georg von Békésy (3 Jun 1899 - 13 Jun 1972)
He was a Hungarian-American physicist and physiologist who discovered the physical mechanism of stimulation within the cochlea with sound is analyzed and communicated in the cochlea. For his discovery, he received the Nobel Prize for physiology in 1961. He developed anatomical techniques that helped in the non-destructive autopsy of the cochlea. Békésy observed the shape of the waves that travel along the basilar membrane by stroboscopic examination of the motion of the particles. He sprinkled silver on the nearly transparent basilar membrane to study his experiment.
David Gregory (3 Jun 1659 - 10 Oct 1708)
He was a Scottish mathematician who published the book “Astronomiae physicae et geometrical elemental” in 1702. This book was an effort to popularize Newtonian science. He also noticed something that Newton had best related to chromatic deviation. Told the different kinds of glasses to spread the colors of the spectrum by different amounts. He also suggested that the combination of two suitable different kinds of glasses might eliminate chromatic deviation.

Camille Flammarion (26 Feb 1842 - 3 Jun 1925)
He was a French astronomer who is best known as the author of popular books on astronomy such as The Atmosphere and Popular Astronomy. He studied the moon, Mars, double and multiple stars. He also supported the idea of canals and higher civilization on Mars. He noted the changes in the craters of the Moon and thought that it was due to the growth of vegetation. He wrote several novels.
Robert Noyce (12 Dec 1927 - 3 Jun 1990)
He was an American engineer and inventor who developed the integrated circuit. The integrated circuit is a system of interconnected transistors on a single microchip of silicon. He, with his colleague Gordon E. Moore, founded Intel corporation and served as the President and chairman of Intel Corporation. He also held several patents for semiconductor devices, structures and methods.

Rutherford Hypothesized The Possibilty of Neutron
Ernest Rutherford hypothesized the possible existence and properties of the neutron in the second Bakerian lecture in 1920. He put out the idea of a particle with mass but no charge. He called it a neutron. He also said that the particle would have a mass slightly greater than that of a proton. He came to be known as the father of nuclear physics. The essential nature of the atomic nucleus was established with the discovery of the neutron by James Chadwick in 1932
The First American Spacewalk
Major Edward White II was the first American astronaut to make a spacewalk in 1965. At an altitude of about 120 miles, he spent 20 minutes outside the Gemini 4 capsule. With his crewmate commander McDivitt, he completed 12 scientific and medical experiments.
