    Neil deGrasse Tyson was born and raised in New York City where he was educated in the public schools clear through his graduation from the Bronx High School of Science. Tyson went on to earn his BA in Physics from Harvard and his PhD in Astrophysics from Columbia.

    Tyson’s professional research interests are broad, but include star formation, exploding stars, dwarf galaxies, and the structure of our Milky Way.

    Tyson is the recipient of twenty honorary doctorates and the NASA Distinguished Public Service Medal, the highest award given by NASA to a non-government citizen.

    "Albert Einstein is undoubtedly one of the most fascinating and influential figures of the modern era. As a preeminent physicist, he radically transformed our understanding of the universe."



    Einstein's Theory of General Relativity


    Theory of General Relativity


    Einstein's theory of general relativity predicted that the space-time around Earth would be not only warped but also twisted by the planet's rotation. Gravity Probe B showed this to be correct.

    Aristotle (384-322 BCE)



    "The Greek philosopher Aristotle proposed that the heavens were literally composed of 55 concentric, crystalline spheres to which the celestial objects were attached and which rotated at different velocities (but the angular velocity was constant for a given sphere), with the Earth at the center... Although Aristotle was not a scientist, it is important to note that he did point out that the Earth had to be sphere since its shadow was always circular. This was in fact a key scientific insight. It allowed Eratosthenes around 200 BC to calculate the circumference of the Earth..."



    Ptolemy (140 CE)

    ancient Greek astronomer, geographer, and mathematician who lived in Alexandria, Egypt during the Helenistic period and considered the Earth the center of the universe 


    Copernicus (1473-1543)

    See the source image

    "In the early 1500s, when virtually everyone believed Earth was the center of the universe, Polish scientist Nicolaus Copernicus proposed that the planets instead revolved around the sun."



    Galileo (1564-1642)

    "Galileo Galilei (1564-1642) was a Tuscan (Italian) astronomer, physicist, mathematician, inventor, and philosopher...in 1609 he built his first telescope and began making observations. The following year he published his first results, where he described the highlands and "seas" of the Moon, four of Jupiter's largest moons, and many newly discovered stars. He also discovered the phases of Venus and sunspots, thereby confirming that the Sun rotates, and that the planets orbit around the Sun, not around the Earth. "


    Kepler (1571-1630)

     "Johannes Kepler was a German mathematician and astronomer who discovered that the Earth and planets travel about the sun in elliptical orbits. He gave three fundamental laws of planetary motion."



    Isaac Newton (1642-1727)

    "Newton, Sir Isaac (1642-1727), mathematician and physicist, one of the foremost scientific intellects of all time...Newton has been regarded for almost 300 years as the founding examplar of modern physical science, his achievements in experimental investigation being as innovative as those in mathematical research."  



    William Herschel (1738-1822)

    See the source image

     "Sir William Herschel was a German-born British astronomer and composer, who is widely credited as the founder of sidereal astronomy for observing the heavenly bodies. He found the planet Uranus and its two moons, and formulated a theory of stellar evolution. Knighted in 1816, Herschel was also the first astronomer to suggest that nebulae are composed of stars."



    Edwin Hubble (1889-1953)

    "The famous British astrophysicist Stephen Hawking wrote in his book A Brief History of Time that Hubble's "discovery that the Universe is expanding was one of the great intellectual revolutions of the 20th century." 



    Cecilia Payne Gaposchkin (1900-1979)

    "Cecilia Payne's PhD thesis was described by Otto Struve, director of Yerkes Observatory, as “the most brilliant PhD thesis ever written in astronomy”.
