Cambridge, Massachusetts
–
Cambridge is a city in Middlesex County, Massachusetts, and is a part of the Boston metropolitan area. According to the 2010 Census, the population was 105,162. As of July 2014, it was the fifth most populous city in the state, behind Boston, Worcester, Springfield, Cambridge was one of the two seats of Middlesex County prior to the abolition of county government in 1997, Lowell was the other. The site for what would become Cambridge was chosen in December 1630, because it was located safely upriver from Boston Harbor, Thomas Dudley, his daughter Anne Bradstreet, and her husband Simon, were among the first settlers of the town. The first houses were built in the spring of 1631, the settlement was initially referred to as the newe towne. Official Massachusetts records show the name capitalized as Newe Towne by 1632, the original village site is in the heart of todays Harvard Square. In the late 19th century, various schemes for annexing Cambridge itself to the city of Boston were pursued and rejected, in 1636, the Newe College was founded by the colony to train ministers. Newe Towne was chosen for the site of the college by the Great and General Court primarily—according to Cotton Mather—to be near the popular, in May 1638 the name of the settlement was changed to Cambridge in honor of the university in Cambridge, England. Hooker and Shepard, Newtownes ministers, and the colleges first president, major benefactor, in 1629, Winthrop had led the signing of the founding document of the city of Boston, which was known as the Cambridge Agreement, after the university. It was Governor Thomas Dudley who, in 1650, signed the charter creating the corporation which still governs Harvard College, Cambridge grew slowly as an agricultural village eight miles by road from Boston, the capital of the colony. By the American Revolution, most residents lived near the Common and Harvard College, with farms and estates comprising most of the town. Coming up from Virginia, George Washington took command of the volunteer American soldiers camped on Cambridge Common on July 3,1775, most of the Tory estates were confiscated after the Revolution. On January 24,1776, Henry Knox arrived with artillery captured from Fort Ticonderoga, a second bridge, the Canal Bridge, opened in 1809 alongside the new Middlesex Canal. The new bridges and roads made what were formerly estates and marshland into prime industrial and residential districts, in the mid-19th century, Cambridge was the center of a literary revolution when it gave the country a new identity through poetry and literature. Cambridge was home to some of the famous Fireside Poets—so called because their poems would often be read aloud by families in front of their evening fires, the Fireside Poets—Henry Wadsworth Longfellow, James Russell Lowell, and Oliver Wendell Holmes—were highly popular and influential in their day. Cambridge was incorporated as a city in 1846, the citys commercial center began to shift from Harvard Square to Central Square, which became the downtown of the city around this time. The coming of the railroad to North Cambridge and Northwest Cambridge then led to three changes in the city, the development of massive brickyards and brickworks between Massachusetts Ave. For many decades, the citys largest employer was the New England Glass Company, by the middle of the 19th century it was the largest and most modern glassworks in the world

United States
–
Forty-eight of the fifty states and the federal district are contiguous and located in North America between Canada and Mexico. The state of Alaska is in the northwest corner of North America, bordered by Canada to the east, the state of Hawaii is an archipelago in the mid-Pacific Ocean. The U. S. territories are scattered about the Pacific Ocean, the geography, climate and wildlife of the country are extremely diverse. At 3.8 million square miles and with over 324 million people, the United States is the worlds third- or fourth-largest country by area, third-largest by land area. It is one of the worlds most ethnically diverse and multicultural nations, paleo-Indians migrated from Asia to the North American mainland at least 15,000 years ago. European colonization began in the 16th century, the United States emerged from 13 British colonies along the East Coast. Numerous disputes between Great Britain and the following the Seven Years War led to the American Revolution. On July 4,1776, during the course of the American Revolutionary War, the war ended in 1783 with recognition of the independence of the United States by Great Britain, representing the first successful war of independence against a European power. The current constitution was adopted in 1788, after the Articles of Confederation, the first ten amendments, collectively named the Bill of Rights, were ratified in 1791 and designed to guarantee many fundamental civil liberties. During the second half of the 19th century, the American Civil War led to the end of slavery in the country. By the end of century, the United States extended into the Pacific Ocean. The Spanish–American War and World War I confirmed the status as a global military power. The end of the Cold War and the dissolution of the Soviet Union in 1991 left the United States as the sole superpower. The U. S. is a member of the United Nations, World Bank, International Monetary Fund, Organization of American States. The United States is a developed country, with the worlds largest economy by nominal GDP. It ranks highly in several measures of performance, including average wage, human development, per capita GDP. While the U. S. economy is considered post-industrial, characterized by the dominance of services and knowledge economy, the United States is a prominent political and cultural force internationally, and a leader in scientific research and technological innovations. In 1507, the German cartographer Martin Waldseemüller produced a map on which he named the lands of the Western Hemisphere America after the Italian explorer and cartographer Amerigo Vespucci

Comet
–
A comet is an icy small Solar System body that, when passing close to the Sun, warms and begins to evolve gasses, a process called outgassing. This produces an atmosphere or coma, and sometimes also a tail. These phenomena are due to the effects of radiation and the solar wind acting upon the nucleus of the comet. Comet nuclei range from a few hundred metres to tens of kilometres across and are composed of collections of ice, dust. The coma may be up to 15 times the Earths diameter, if sufficiently bright, a comet may be seen from the Earth without the aid of a telescope and may subtend an arc of 30° across the sky. Comets have been observed and recorded since ancient times by many cultures, Comets usually have highly eccentric elliptical orbits, and they have a wide range of orbital periods, ranging from several years to potentially several millions of years. Short-period comets originate in the Kuiper belt or its associated scattered disc, long-period comets are thought to originate in the Oort cloud, a spherical cloud of icy bodies extending from outside the Kuiper belt to halfway to the nearest star. Long-period comets are set in motion towards the Sun from the Oort cloud by gravitational perturbations caused by passing stars, hyperbolic comets may pass once through the inner Solar System before being flung to interstellar space. The appearance of a comet is called an apparition, Comets are distinguished from asteroids by the presence of an extended, gravitationally unbound atmosphere surrounding their central nucleus. This atmosphere has parts termed the coma and the tail, however, extinct comets that have passed close to the Sun many times have lost nearly all of their volatile ices and dust and may come to resemble small asteroids. Asteroids are thought to have a different origin from comets, having formed inside the orbit of Jupiter rather than in the outer Solar System, the discovery of main-belt comets and active centaur minor planets has blurred the distinction between asteroids and comets. As of November 2014 there are 5,253 known comets, however, this represents only a tiny fraction of the total potential comet population, as the reservoir of comet-like bodies in the outer Solar System is estimated to be one trillion. Roughly one comet per year is visible to the eye, though many of those are faint. Particularly bright examples are called Great Comets, the word comet derives from the Old English cometa from the Latin comēta or comētēs. That, in turn, is a latinisation of the Greek κομήτης, Κομήτης was derived from κομᾶν, which was itself derived from κόμη and was used to mean the tail of a comet. The astronomical symbol for comets is ☄, consisting of a disc with three hairlike extensions. The solid, core structure of a comet is known as the nucleus, cometary nuclei are composed of an amalgamation of rock, dust, water ice, and frozen gases such as carbon dioxide, carbon monoxide, methane, and ammonia. As such, they are described as dirty snowballs after Fred Whipples model

Astronomy
–
Astronomy is a natural science that studies celestial objects and phenomena. It applies mathematics, physics, and chemistry, in an effort to explain the origin of those objects and phenomena and their evolution. Objects of interest include planets, moons, stars, galaxies, and comets, while the phenomena include supernovae explosions, gamma ray bursts, more generally, all astronomical phenomena that originate outside Earths atmosphere are within the purview of astronomy. A related but distinct subject, physical cosmology, is concerned with the study of the Universe as a whole, Astronomy is the oldest of the natural sciences. The early civilizations in recorded history, such as the Babylonians, Greeks, Indians, Egyptians, Nubians, Iranians, Chinese, during the 20th century, the field of professional astronomy split into observational and theoretical branches. Observational astronomy is focused on acquiring data from observations of astronomical objects, theoretical astronomy is oriented toward the development of computer or analytical models to describe astronomical objects and phenomena. The two fields complement each other, with theoretical astronomy seeking to explain the results and observations being used to confirm theoretical results. Astronomy is one of the few sciences where amateurs can play an active role, especially in the discovery. Amateur astronomers have made and contributed to many important astronomical discoveries, Astronomy means law of the stars. Astronomy should not be confused with astrology, the system which claims that human affairs are correlated with the positions of celestial objects. Although the two share a common origin, they are now entirely distinct. Generally, either the term astronomy or astrophysics may be used to refer to this subject, however, since most modern astronomical research deals with subjects related to physics, modern astronomy could actually be called astrophysics. Few fields, such as astrometry, are purely astronomy rather than also astrophysics, some titles of the leading scientific journals in this field includeThe Astronomical Journal, The Astrophysical Journal and Astronomy and Astrophysics. In early times, astronomy only comprised the observation and predictions of the motions of objects visible to the naked eye, in some locations, early cultures assembled massive artifacts that possibly had some astronomical purpose. Before tools such as the telescope were invented, early study of the stars was conducted using the naked eye, most of early astronomy actually consisted of mapping the positions of the stars and planets, a science now referred to as astrometry. From these observations, early ideas about the motions of the planets were formed, and the nature of the Sun, Moon, the Earth was believed to be the center of the Universe with the Sun, the Moon and the stars rotating around it. This is known as the model of the Universe, or the Ptolemaic system. The Babylonians discovered that lunar eclipses recurred in a cycle known as a saros

Astronomer
–
An astronomer is a scientist in the field of astronomy who concentrates their studies on a specific question or field outside of the scope of Earth. They look at stars, planets, moons, comets and galaxies, as well as other celestial objects — either in observational astronomy. Examples of topics or fields astronomers work on include, planetary science, solar astronomy, there are also related but distinct subjects like physical cosmology which studies the Universe as a whole. Astronomers usually fit into two types, Observational astronomers make direct observations of planets, stars and galaxies, and analyze the data, theoretical astronomers create and investigate models of things that cannot be observed. They use this data to create models or simulations to theorize how different celestial bodies work, there are further subcategories inside these two main branches of astronomy such as planetary astronomy, galactic astronomy or physical cosmology. Today, that distinction has disappeared and the terms astronomer. Professional astronomers are highly educated individuals who typically have a Ph. D. in physics or astronomy and are employed by research institutions or universities. They spend the majority of their time working on research, although quite often have other duties such as teaching, building instruments. The number of astronomers in the United States is actually quite small. The American Astronomical Society, which is the organization of professional astronomers in North America, has approximately 7,000 members. This number includes scientists from other such as physics, geology. The International Astronomical Union comprises almost 10,145 members from 70 different countries who are involved in research at the Ph. D. level. Before CCDs, photographic plates were a method of observation. Modern astronomers spend relatively little time at telescopes usually just a few weeks per year, analysis of observed phenomena, along with making predictions as to the causes of what they observe, takes the majority of observational astronomers time. Astronomers who serve as faculty spend much of their time teaching undergraduate and graduate classes, most universities also have outreach programs including public telescope time and sometimes planetariums as a public service to encourage interest in the field. Those who become astronomers usually have a background in maths, sciences. Taking courses that teach how to research, write and present papers are also invaluable, in college/university most astronomers get a Ph. D. in astronomy or physics. Keeping in mind how few there are it is understood that graduate schools in this field are very competitive

Asteroid
–
Asteroids are minor planets, especially those of the inner Solar System. The larger ones have also been called planetoids and these terms have historically been applied to any astronomical object orbiting the Sun that did not show the disc of a planet and was not observed to have the characteristics of an active comet. As minor planets in the outer Solar System were discovered and found to have volatile-based surfaces that resemble those of comets, in this article, the term asteroid refers to the minor planets of the inner Solar System including those co-orbital with Jupiter. There are millions of asteroids, many thought to be the remnants of planetesimals. The large majority of known asteroids orbit in the belt between the orbits of Mars and Jupiter, or are co-orbital with Jupiter. However, other orbital families exist with significant populations, including the near-Earth objects, individual asteroids are classified by their characteristic spectra, with the majority falling into three main groups, C-type, M-type, and S-type. These were named after and are identified with carbon-rich, metallic. The size of asteroids varies greatly, some reaching as much as 1000 km across, asteroids are differentiated from comets and meteoroids. In the case of comets, the difference is one of composition, while asteroids are composed of mineral and rock, comets are composed of dust. In addition, asteroids formed closer to the sun, preventing the development of the aforementioned cometary ice, the difference between asteroids and meteoroids is mainly one of size, meteoroids have a diameter of less than one meter, whereas asteroids have a diameter of greater than one meter. Finally, meteoroids can be composed of either cometary or asteroidal materials, only one asteroid,4 Vesta, which has a relatively reflective surface, is normally visible to the naked eye, and this only in very dark skies when it is favorably positioned. Rarely, small asteroids passing close to Earth may be visible to the eye for a short time. As of March 2016, the Minor Planet Center had data on more than 1.3 million objects in the inner and outer Solar System, the United Nations declared June 30 as International Asteroid Day to educate the public about asteroids. The date of International Asteroid Day commemorates the anniversary of the Tunguska asteroid impact over Siberia, the first asteroid to be discovered, Ceres, was found in 1801 by Giuseppe Piazzi, and was originally considered to be a new planet. In the early half of the nineteenth century, the terms asteroid. Asteroid discovery methods have improved over the past two centuries. This task required that hand-drawn sky charts be prepared for all stars in the band down to an agreed-upon limit of faintness. On subsequent nights, the sky would be charted again and any moving object would, hopefully, the expected motion of the missing planet was about 30 seconds of arc per hour, readily discernible by observers

Tennis
–
Tennis is a racket sport that can be played individually against a single opponent or between two teams of two players each. Each player uses a racket that is strung with cord to strike a hollow rubber ball covered with felt over or around a net. The object of the game is to play the ball in such a way that the opponent is not able to play a valid return, the player who is unable to return the ball will not gain a point, while the opposite player will. Tennis is an Olympic sport and is played at all levels of society, the sport can be played by anyone who can hold a racket, including wheelchair users. The modern game of tennis originated in Birmingham, England, in the late 19th century as lawn tennis and it had close connections both to various field games such as croquet and bowls as well as to the older racket sport of real tennis. The rules of tennis have changed little since the 1890s, two exceptions are that from 1908 to 1961 the server had to keep one foot on the ground at all times, and the adoption of the tiebreak in the 1970s. Tennis is played by millions of players and is also a popular worldwide spectator sport. Historians believe that the ancient origin lay in 12th century northern France. Louis X of France was a player of jeu de paume, which evolved into real tennis. Louis was unhappy with playing tennis outdoors and accordingly had indoor, in due course this design spread across royal palaces all over Europe. Because of the accounts of his death, Louis X is historys first tennis player known by name. Another of the enthusiasts of the game was King Charles V of France. It wasnt until the 16th century that rackets came into use, and the game began to be called tennis, from the French term tenez, an interjection used as a call from the server to his opponent. It was popular in England and France, although the game was played indoors where the ball could be hit off the wall. Henry VIII of England was a big fan of this game, during the 18th century and early 19th century, as real tennis declined, new racket sports emerged in England. This in turn led to the codification of rules for many sports, including lawn tennis, most football codes, lawn bowls. In 1872, along with two doctors, they founded the worlds first tennis club in Leamington Spa. Evans, turfgrass agronomist, Sports historians all agree that deserves much of the credit for the development of modern tennis, according to Honor Godfrey, museum curator at Wimbledon, Wingfield popularized this game enormously

Occidental College
–
Occidental College is a private, co-educational liberal arts college located in the Eagle Rock neighborhood of Los Angeles, California, United States. Founded in 1887 by clergy and members of the Presbyterian Church, Occidental College is often referred to as Oxy for short. In 2017, the Wall Street Journal/Times Higher Education College Rankings placed Occidental 27th on its list of the top 100 liberal arts colleges in the United States. The New York Times ranked Occidental No.20 on its list of the most economically diverse U. S. colleges and universities, the Carnegie Foundation for the Advancement of Teaching selected Occidental as a community engagement institution. The college was named to the 2014 Presidents Higher Education Community Service Honor Roll with distinction, Occidental is also one of the most racially diverse liberal arts colleges, with approximately 50% of the student body identitifying as students of color. The college is ranked No.7 for liberal arts colleges, Oxy was ranked the sixth Most Beautiful college campus by Newsweek in 2012. Occidental College was founded on April 20,1887, by a group of Presbyterian clergy, missionaries, and laymen, including James George Bell, Lyman Stewart, the cornerstone of the schools first building was laid in September 1887 in the Boyle Heights neighborhood of Los Angeles. The colleges first term began a year later with 27 male and 13 female students, in 1896, the Boyle Heights building was destroyed by fire. The college temporarily relocated to the old St. Vincents College campus on Hill Street before a new site was selected in Highland Park in 1898, eventually, the college erected three main buildings, the Academy Building, the Stimson Library, and the Hall of Arts and Letters. In 1909, the Pomona College Board of Trustees suggested a merger between Pomona and Occidental, but the proposal came to nothing, the following year, the college severed formal ties with the Presbyterian Church and became a non-sectarian, non-denominational institution. The small size of the 15-acre campus and the disruption caused by frequent freight trains pushed the colleges trustees to find a new location, in 1912, the school began construction of a new campus located in Los Angeles Eagle Rock neighborhood. That same year, Occidental President John Willis Baer announced the decision to convert Occidental College into an all-mens institution. However, students and faculty protested, and the idea was abandoned, two weeks after Booker T. Washington came to visit Occidental, on March 27,1914, Swan, Fowler, and Johnson Halls were dedicated at its new Eagle Rock campus. Patterson Field, today one of the oldest collegiate sports stadiums in Los Angeles, was opened in 1916, in April 1917, shortly after the United States entered World War I, the college formed a Students Army Training Corps to aid the war effort. The Delta of California Chapter of Phi Beta Kappa was established at Occidental in 1926, at a time when the other chapters in California were at Stanford, UC Berkeley. During World War II, many students left Occidental to fight in the war, in July 1943, the U. S. Navy established a Navy V-12 officer training program on campus that produced hundreds of graduates before it was disbanded at the end of the war in 1945. Rhodes scholars Aaron Segal and John Paden were among the 10 Occidental students who participated in Crossroads Africa that year, in 1969,42 students were suspended for peacefully protesting military recruiting on campus. One year later, faculty voted to suspend classes in the wake of the Kent State shootings, subsequently, Oxy students wrote 7,000 letters to Washington D. C. protesting U. S. involvement in the war in Southeast Asia

Southern California
–
Southern California, often abbreviated as SoCal, is a geographic and cultural region that generally comprises Californias 10 southernmost counties. The region is described as eight counties, based on demographics and economic ties, Imperial, Los Angeles, Orange, Riverside, San Bernardino, San Diego, Santa Barbara. The more extensive 10-county definition, which includes Kern and San Luis Obispo counties, is used and is based on historical political divisions. Southern California is an economic center for the state of California. The 8-county and 10-county definitions are not used for the greater Southern California Megaregion, the megaregions area is more expansive, extending east into Las Vegas, Nevada and south across the Mexican border into Tijuana.5 million people. With over 22 million people, Southern California contains roughly 60 percent of Californias population, located east of Southern California is the Colorado Desert and the Colorado River at the border with Arizona. The Mojave Desert is located at the border with the state of Nevada while towards the south is the Mexico–United States border, within Southern California are two major cities, Los Angeles and San Diego, as well as three of the countrys largest metropolitan areas. With a population of 3,792,621, Los Angeles is the most populous city in California and the second most populous in the United States. South of Los Angeles and with a population of 1,307,402 is San Diego, the second most populous city in the state and the eighth most populous in the nation. The counties of Los Angeles, Orange, San Diego, San Bernardino, and Riverside are the five most populous in the state, the motion picture, television, and music industry are centered in the Los Angeles area in Southern California. Hollywood, a district within Los Angeles, gives its name to the American motion picture industry, headquartered in Southern California are The Walt Disney Company, Sony Pictures, Universal, MGM, Paramount Pictures, 20th Century Fox, and Warner Brothers. Universal, Warner Brothers, and Sony also run major record companies, Southern California is also home to a large homegrown surf and skateboard culture. Companies such as Vans, Volcom, Quiksilver, No Fear, RVCA, some of the worlds biggest action sports events, including the X Games, Boost Mobile Pro, and the U. S. Open of Surfing, are all held in Southern California. Southern California is also important to the world of yachting, the annual Transpacific Yacht Race, or Transpac, from Los Angeles to Hawaii, is one of yachtings premier events. The San Diego Yacht Club held the Americas Cup, the most prestigious prize in yachting, from 1988 to 1995, Southern California is home to many sports franchises and sports networks such as Fox Sports Net. Many locals and tourists frequent the Southern California coast for its popular beaches, the desert city of Palm Springs is popular for its resort feel and nearby open spaces. Southern California is not a geographic designation and definitions of what constitutes Southern California vary. Geographically, Californias North-South midway point lies at exactly 37°958.23 latitude, around 11 miles south of San Jose, however, when the state is divided into two areas, the term Southern California usually refers to the 10 southernmost counties of the state

University of California, Los Angeles
–
The University of California, Los Angeles is a public research university in the Westwood district of Los Angeles, California, United States. It became the Southern Branch of the University of California in 1919 and it offers 337 undergraduate and graduate degree programs in a wide range of disciplines. UCLA enrolls about 31,000 undergraduate and 13,000 graduate students, and had 119,000 applicants for Fall 2016, including transfer applicants, the university is organized into six undergraduate colleges, seven professional schools, and four professional health science schools. Fourteen Nobel laureates, three Fields Medalists, two Chief Scientists of the U. S. Air Force and three Turing Award winners have been faculty, researchers, or alumni, the university was elected to the Association of American Universities in 1974. The Times Higher Education World University Rankings for 2015–2016 ranked UCLA 16th in the world for academics, in 2015-2016, UCLA ranked 12th in the world by the Academic Ranking of World Universities and 31st in the 2016/17 QS World University Rankings. UCLA student-athletes compete as the Bruins in the Pac-12 Conference, the Bruins won 126 national championships, including 113 NCAA team championships, more than any other university. UCLA student-athletes, coaches and staff won 251 Olympic medals,126 gold,65 silver and 60 bronze, UCLA student-athletes competed in every Olympics since 1920 with one exception, and won a gold medal in every Olympics that the United States participated in since 1932. The State Normal School at Los Angeles opened on August 29,1882, the facility included an elementary school where teachers-in-training could practice their technique with children. That elementary school is related to the present day version, UCLA Lab School, in 1887, the school became known as the Los Angeles State Normal School. In 1914, the moved to a new campus on Vermont Avenue in East Hollywood. However, David Prescott Barrows, the new President of the University of California, the same legislation added its general undergraduate program, the College of Letters and Science. After the athletic teams entered the Pacific Coast conference in 1926, the Southern Branch student council adopted the nickname Bruins, in 1927, the Regents renamed the Southern Branch the University of California at Los Angeles. In the same year, the state broke ground in Westwood on land sold for $1 million, less than one-third its value, by real estate developers Edwin and Harold Janss, the campus in Westwood opened to students in 1929. The original four buildings were the College Library, Royce Hall, the Physics-Biology Building, the first undergraduate classes on the new campus were held in 1929 with 5,500 students. A timeline of the history can be found on its website, during its first 32 years, UCLA was treated as an off-site department of UC. As such, its presiding officer was called a provost, in 1951, UCLA was formally elevated to co-equal status with UC Berkeley, and its presiding officer Raymond B. Allen was the first chief executive to be granted the title of chancellor. The appointment of Franklin David Murphy to the position of Chancellor in 1960 helped spark an era of growth of facilities. By the end of the decade, UCLA had achieved distinction in a range of subjects

University of California, Berkeley
–
The University of California, Berkeley, is a public research university located in Berkeley, California. In 1960s, UC Berkeley was particularly noted for the Free Speech Movement as well as the Anti-Vietnam War Movement led by its students. S, Department of Energy, and is home to many world-renowned research institutes and organizations including Mathematical Sciences Research Institute and Space Sciences Laboratory. Faculty member J. R. Oppenheimer, the father of the atomic bomb, Lawrence Livermore Lab also discovered or co-discovered six chemical elements. The Academic Ranking of World Universities also ranks the University of California, Berkeley, third in the world overall, in 1866, the private College of California purchased the land comprising the current Berkeley campus. Ten faculty members and almost 40 students made up the new University of California when it opened in Oakland in 1869, billings was a trustee of the College of California and suggested that the college be named in honor of the Anglo-Irish philosopher George Berkeley. In 1870, Henry Durant, the founder of the College of California, with the completion of North and South Halls in 1873, the university relocated to its Berkeley location with 167 male and 22 female students and held its first classes. In 1905, the University Farm was established near Sacramento, ultimately becoming the University of California, by the 1920s, the number of campus buildings had grown substantially, and included twenty structures designed by architect John Galen Howard. Robert Gordon Sproul served as president from 1930 to 1958, by 1942, the American Council on Education ranked UC Berkeley second only to Harvard University in the number of distinguished departments. During World War II, following Glenn Seaborgs then-secret discovery of plutonium, UC Berkeley physics professor J. Robert Oppenheimer was named scientific head of the Manhattan Project in 1942. Along with the Lawrence Berkeley National Laboratory, Berkeley is now a partner in managing two other labs, Los Alamos National Laboratory and Lawrence Livermore National Laboratory, originally, military training was compulsory for male undergraduates, and Berkeley housed an armory for that purpose. In 1917, Berkeleys ROTC program was established, and its School of Military Aeronautics trained future pilots, including Jimmy Doolittle, both Robert McNamara and Frederick C. Weyand graduated from UC Berkeleys ROTC program, earning B. A. degrees in 1937 and 1938, in 1926, future fleet admiral Chester W. Nimitz established the first Naval Reserve Officers Training Corps unit at Berkeley. The Board of Regents ended compulsory military training at Berkeley in 1962, during the McCarthy era in 1949, the Board of Regents adopted an anti-communist loyalty oath. A number of faculty members objected and were dismissed, ten years passed before they were reinstated with back pay, in 1952, the University of California became an entity separate from the Berkeley campus. Each campus was given autonomy and its own Chancellor. Then-president Sproul assumed presidency of the entire University of California system, Berkeley gained a reputation for student activism in the 1960s with the Free Speech Movement of 1964 and opposition to the Vietnam War. In the highly publicized Peoples Park protest in 1969, students and the school conflicted over use of a plot of land, then governor of California Ronald Reagan called the Berkeley campus a haven for communist sympathizers, protesters, and sex deviants. Modern students at Berkeley are less active, with a greater percentage of moderates and conservatives

Dwarf planet
–
A dwarf planet is a planetary-mass object that is neither a planet nor a natural satellite. The International Astronomical Union currently recognizes five dwarf planets, Ceres, Pluto, Haumea, Makemake, another hundred or so known objects in the Solar System are suspected to be dwarf planets. Individual astronomers recognize several of these, and in August 2011 Mike Brown published a list of 390 candidate objects, Stern states that there are more than a dozen known dwarf planets. Only two of these bodies, Ceres and Pluto, have observed in enough detail to demonstrate that they actually fit the IAUs definition. The IAU accepted Eris as a dwarf planet because it is more massive than Pluto and they subsequently decided that unnamed trans-Neptunian objects with an absolute magnitude brighter than +1 are to be named under the assumption that they are dwarf planets. The classification of bodies in other systems with the characteristics of dwarf planets has not been addressed. Starting in 1801, astronomers discovered Ceres and other bodies between Mars and Jupiter which were for some decades considered to be planets. Between then and around 1851, when the number of planets had reached 23, astronomers started using the asteroid for the smaller bodies. With the discovery of Pluto in 1930, most astronomers considered the Solar System to have nine planets and it was roughly one-twentieth the mass of Mercury, which made Pluto by far the smallest planet. Although it was more than ten times as massive as the largest object in the asteroid belt, Ceres. In the 1990s, astronomers began to find objects in the region of space as Pluto. Many of these shared several of Plutos key orbital characteristics, and Pluto started being seen as the largest member of a new class of objects and this led some astronomers to stop referring to Pluto as a planet. Several terms, including subplanet and planetoid, started to be used for the now known as dwarf planets. By 2005, three trans-Neptunian objects comparable in size to Pluto had been reported and it became clear that either they would also have to be classified as planets, or Pluto would have to be reclassified.
