Albert Einstein:

March 14, 1879 - April 18 1955

Bio:

Albert Einstein was born on March 14th, 1879 in the German city of Ulm. His father Hermann was a salesman and engineer. A year after he was born, his family relocated to Munich where his father and uncle established an electrical equipment manufacturing company. This event in his early life may have set the stage for his interest in science and mathematics. His father would share his engineering knowledge with the young Albert who thrived on learning about how things worked. Albert’s formal education began with him attending catholic schools even though he was of Jewish descent. His family did not actively practice the Jewish faith. Over the years his education was a varied one and he never hid his disdain for organized teaching. He attended several different institutions of learning in a number of locations. Einstein married a woman he had met at the Swiss Federal Polytechnic in Zurich. The marriage occurred about one year after he fathered a daughter by the woman. There is some mystery as to the fate of the baby. Some believe the girl may have been put up for adoption while others think she may have died after contracting scarlet fever while still an infant. The couple would have two sons before divorcing in 1919 after 16 years of marriage. Einstein would marry his cousin a few months later, after having begun a relationship with her 7 years prior.Besides the theory of relativity, Einstein’s contribution to science is unparalleled in its depth and magnitude. He was responsible for literally hundreds of article and books as well as collaborating with other scientists on numerous occasions. Einstein’s Annus-Mirabilas Papers of 1905 contained material relating to the theory of relativity, E = mc2, Brownian Motion and photoelectric effects. His Theory of Critical Opalescence publication explains, among other things, why the sky is blue. His Modern Quantum Theory was an upgrade to quantum theory and mechanics.

Galileo Galilei:

February 15, 1564 - January 8, 1642

Bio:

While he was in a service in the cathedral one day, he was distracted by a bronze lamp hanging from the ceiling. He noticed that the lamp was drawn aside so as to light the room better. When it was released, the lamp oscillated back and forward gradually with decreasing amplitude. Galileo used the pulse of his heart to keep the time and was surprised to discover the lamp’s oscillation period was unaffected by the arc’s size of oscillation. He later proved through an experiment that the period taken by a swinging pendulum did not depend on the bob’s weight. He proved that the period is dependent only on the pendulum’s length. The pendulum was what formed his interest in astronomy and science. When he later got the chance to attend a lecture in geometry, this further fueled his interest in astronomy. Galileo then changed from medicine and decided to study science, philosophy, and mathematics. These were subjects in which he believed he possessed a strong natural talent. Galileo’s Career In 1589, Galileo was appointed the mathematics professor at Pisa. In 1591, his father, Vincenzo Galilei, died and as the eldest son, Galileo had to take up the position of the bread winner. Since he was not well paid as the mathematics professor, he looked for a much better post. In 1952, Galileo become the mathematics professor at the University of Padua. He was able to secure a job with a salary that was almost three times more than the one he received at Pisa. He held this position until 1610 and described this period as the happiest time of his life. He focused on a number of experiments, such as the speed of fall of various objects, the pendulum effect, and mechanics. Contributions to Astronomy

Urbain Le Verrier:

March 11, 1811 - September 23, 1877

Bio:

Urbain Jean Joseph Le Verrier was born in 1811 at Saint-Lô, France. At the age of 26, he was appointed a teacher of astronomy at the Ecole Polytechnic Paris. Immediately after his appointment he began an intensive study of the motion of Mercury. He compiled extensive tables detailing the planet's motion, including its unusual characteristic of a varying perihelion. By 1845 Le Verrier had become interested in the motion of the planet Uranus. Uranus did not have the orbit scientists expected it to have based on their mathematical calculations. Le Verrier set out to determine why. Through mathematical calculations, he predicted the presence of another planet beyond Uranus. The gravitational pull of this planet would explain the unusual motion of Uranus. Le Verrier gave his calculations to astronomer Johann Gottried Galle at the Berlin Observatory. Using Le Verrier's calculations, Galle was able to observe the planet within one hour of starting. Le Verrier expected to be declared the sole discoverer of Neptune, but months prior to his calculations being completed John Couch Adams, an English mathematician, had accomplished the same feat. As a consequence, Le Verrier and Adams share the honor as Neptune's discoverers. In 1854, Le Verrier became director of the Observatory of Paris. At the time, this observatory was in decay. Le Verrier reestablished the observatory as a place where good science was taking place. He often used very tough measures at the observatory. As a consequence, a storm of protest led to his removal as director in 1870. He was reinstated as director in 1873. Urbain Le Verrier died in Paris in 1877.

William Herschel:

Bio:

In 1781, the German-English astronomer William Herschel sent shockwaves through the world of science when he discovered the planet Uranus. Since humans began observing the stars, the general consensus was that there were only five other planets in addition to the earth orbiting our sun. That there could be sixth planet in the heavens was almost unthinkable.

Clyde Tombaugh:

February 4, 1906 - January 17, 1997

Bio:

Born in Streator, Illinois, Tombaugh and his family moved to Burdette, Kansas, when he was still young. Unable to go to college because he was needed on his family’s farm, Tombaugh was largely self-taught. When he was still young, he began to build his own telescopes and was hired to work at the Lowell Observatory in Flagstaff, Arizona, which was and still is run by members of the Lowell family. He stayed at the Observatory from 1929 to 1945. During his time there, Tombaugh attended the University of Kansas. He worked at the observatory during his summer breaks. Tombaugh’s Discoveries At Lowell Observatory, Tombaugh was given the job of actively searching for Pluto. He used a 13-inch astrograph, which is a telescope that takes pictures of the stars. The blink microscope helped him tell the different images apart and compare them. A moving object would change position while the stars remained motionless. Though he eventually discovered Pluto this way on February 18, 1930, Tombaugh found many asteroids in the meantime. The first one he found he named after his daughter, Annette. He was fond of naming asteroids after members of his family. Besides the hundreds of asteroids Tombaugh discovered, he also discovered variable stars, which change in brightness over time. He also found clusters of stars and galaxies and at least one supercluster of galaxies. He also claimed to have seen UFOs in New Mexico. Though he prided himself on his scientific objectivity, he could not rule out the possibility that these UFOs had an extraterrestrial origin. He became part of a project that searched for near-earth satellites, but claimed that the search, in the end, was unsuccessful.

Percival Lowell:

March 13, 1855- November 12, 1916

Bio:

Percival Lowell, American astronomer who predicted the existence of a planet beyond the orbit of Neptune and initiated the search that ended in the discovery of Pluto. A member of the distinguished Lowell family of Massachusetts, he devoted himself (1883–93) to literature and travel, much of the time in the Far East, which he described in Chosön (1886), The Soul of the Far East (1888), Noto (1891), and Occult Japan (1895). During part of this time he was counselor and foreign secretary to the Korean Special Mission to the United States. In the 1890s, inspired by Giovanni Schiaparelli’s discovery of “canals” on Mars, Lowell decided to devote his fortune and energy to the study of Mars. After careful consideration of desirable sites, he built a private observatory at Flagstaff, Ariz. Lowell championed the now-abandoned theory that intelligent inhabitants of a dying Mars constructed a planet-wide system of irrigation, utilizing water from the polar ice caps, which melt annually. He thought the canals were bands of cultivated vegetation dependent on this irrigation. Among his many books on this subject is Mars and Its Canals (1906). Lowell’s theory, long vigorously opposed, was finally put to rest by information received from the U.S. spacecraft Mariner 4 when it flew past Mars in July 1965. Early in the 20th century Lowell made an elaborate mathematical study of the orbit of Uranus. He attributed certain irregularities to the action of an unseen planet beyond Neptune and calculated its probable position. In 1905 he organized a systematic search for the planet by the staff of his observatory, and in 1915 he published his “Memoir on a Trans-Neptunian Planet.” Fourteen years after his death the search culminated in the discovery of Pluto.

IsAac NewtoN:

January 4, 1643- March 31, 1727

Bio:

Isaac Newton was born in Woolsthorpe, England on December 25th, 1642. He went to Grantham grammar school, but he was more interested in making mechanical models than he was in studying and was considered a poor student. His boyish hobbies led to a small windmill that could grind corn and wheat, a water clock and a sundial. Newton left school when he was 14 because his widowed mother needed him to help with their farm. He was no better at this than he was at being a schoolboy and he was eventually sent back to school. Newton entered Trinity College at Cambridge University in 1661. Here again he was a mediocre student. He left school in 1665 without distinction, but returned in 1667 as a fellow. In 1669 he became professor of mathematics and gave lectures on geometry, astronomy, optics and mathematics. He later quit and went to work for the government and was made a fellow of the Royal Society in 1672.Newton claimed that he began to think about a theory of gravity while he was drinking tea one afternoon and saw an apple fall from a tree. This made him realize that the same force that made the apple fall is what keeps the moon in its orbit. He extrapolated from this to realize that gravity makes every pair of bodies in the universe attracted each other. He also learned that the strength of gravity depends on the amount of matter in the bodies being attracted and the distance between the bodies. Newton also showed why the apple might fall straight to earth while the moon moved in a circle around the earth. He showed that the moon was falling constantly toward the earth and if it moved in a straight line, it would fly out of its orbit. In 1684, Edmund Halley, the English astronomer, urged Newton to publish his findings on gravity. In 1687 Newton’s discoveries were published in Philosophiae Naturalis Principia Mathematica. Even today this book is considered one of the great scientific books of all time. In 1704, Newton published Optiks. In this book, he explained why bodies appear to be colored. This laid the foundation for spectrum analysis, which allows scientists to determine the temperature, chemical composition and speed of bodies like distant stars. Newton also discovered that sunlight is a mix of light of all colors while passing sunlight through a prism.

Vera Rubin:

July 23, 1928- December 25, 2016

Bio:

Vera Rubin, American astronomer who made groundbreaking observations that provided evidence for the existence of a vast amount of dark matter in the universe. The Swiss American astronomer Fritz Zwicky had in 1933 observed that the mass of stars within a galaxy that he observed was insufficient to keep the galaxy from flying apart, and he deduced that there must be some “missing mass” holding the galaxy together. In the 1970s Rubin, working with her colleague Kent Ford, began measuring the rotation of spiral galaxies and found that stars on the outer edges of galaxies spun at least as fast around the centre as those in the inner regions, counter to Rubin’s expectations. Rubin examined more than 60 spiral galaxies and found that her original observations were borne out in every case. The existence of a substantial amount of dark matter provided the most-reasonable explanation for those findings. Rubin studied astronomy at Vassar College, graduating in 1948. She earned (1951) a master’s degree from Cornell University and (1954) a Ph.D. from Georgetown University. Her doctoral thesis showed that galaxies are not distributed uniformly but instead are found in clumps. After teaching at Montgomery College and at Georgetown, Rubin joined (1965) the Carnegie Institution, where she spent the majority of her career. In the mid-1960s she was the first woman permitted to use the Hale Telescope at the Palomar Observatory at Caltech. Rubin met with resistance during her career because of her sex, and she was an outspoken advocate for women in the sciences. She was admitted (1981) into the National Academy of Sciences and was awarded (1993) the National Medal of Science.

Bio:

Edwin Hubble was born in 1889. During his early years, he was noted more for his prowess in athletics than in his intellectual capabilities. He was a gifted athlete who played football, basketball, baseball and track. In fact, he ran track in both college and high school. He went to school at the University of Chicago and concentrated mainly on math, philosophy, and astronomy. These earned him a bachelor’s degree in science in 1910. He was married to one wife, Grace Hubble
Hubble’s father wanted him to study law. As a result, Edwin studied law at the University of Chicago and then later at Oxford. Since he did not have a passion for law, he began teaching physics, math, and Spanish at the New Albany High School after his father died. At the age of 25, he gave up his teaching career and became a professional astronomer.
