Edwin Hubble is sometimes regarded as the greatest astronomer of all time, mainly because of his contributions in the fields of extragalactic astronomy and observable cosmology. Many of his findings include discovering nebulae outside of our galaxy, created a system of classifying galaxies, creating Hubble’s law; which states that redshift increases with distance; and much more. Although he never received a noble prize, he is still considered a great scientist.
Carl Edward Sagan ( November 9, 1934 – December 20, 1996) was an American astronomer , cosmologist , astrophysicist , astrobiologist , author, science popularizer, and science communicator in astronomy and other natural sciences. He is best known for his work as a science popularizer and communicator. His best known scientific contribution is research on extraterrestrial life , including experimental demonstration of the production of amino acids from basic chemicals by radiation .
Edwin Schrodinger: A Nobel Prize-winning Austrian physicist who developed a number of fundamental principles in the field of quantum theory, which formed the basis of wave mechanics: he formulated the wave equation (stationary and time-dependent Schrodinger equation), and revealed the identity of his development of the formalism and matrix mechanics. Schrodinger’s cat is a thought experiment, described as a paradox. The scenario presents a cat that may be both simultaneously both alive and dead, a state known as quantum superposition.
Nikola Tesla was an inventor, electrical engineer, mechanical engineer, physicist, and futurist who is best known for his contributions to the design of the modern alternating current electricity system. Alberto Einstein described Tesla as the greatest mind in the world ever. Attempting to develop inventions he could patent and market, Tesla conducted a range of experiments with mechanical oscillators and generators, electrical discharge tubes, and early X-ray imaging. Tesla was noted for his showmanship at public lectures.
Ernest Rutherford, 1st Baron Rutherford of Nelson (30 August 1871 – 19 October 1937) was a New Zealand-born British physicist who came to be known as the father of nuclear physics. Encyclopædia Britannica considers him to be the greatest experimentalist since Michael Faraday (1791–1867).
