When Bell objected that he lacked the necessary knowledge, Henry firmly advised: "Get it!" On June 25, 1876, Bell's experimental telephone, using a different design, was demonstrated at the Centennial Exhibition in Philadelphia , where Henry was one of the judges for electrical exhibits. On 13 January 1877, Bell demonstrated his instruments to Henry at

However, the effect did not become widely known until 1820, when Ørsted performed a similar experiment. Ørsted's work influenced Ampère to conduct further experiments, which eventually gave rise to a new area of physics: electrodynamics. By determining
2560-474: A magnetic field transforms to a field with a nonzero electric component and conversely, a moving electric field transforms to a nonzero magnetic component, thus firmly showing that the phenomena are two sides of the same coin. Hence the term "electromagnetism". (For more information, see Classical electromagnetism and special relativity and Covariant formulation of classical electromagnetism .) Today few problems in electromagnetism remain unsolved. These include:
2720-446: A magnetic needle using a Voltaic pile. The factual setup of the experiment is not completely clear, nor if current flowed across the needle or not. An account of the discovery was published in 1802 in an Italian newspaper, but it was largely overlooked by the contemporary scientific community, because Romagnosi seemingly did not belong to this community. An earlier (1735), and often neglected, connection between electricity and magnetism
2880-442: A major fundraising drive known as "A Campaign for Princeton" was conducted. President Harold T. Shapiro would succeed Bowen and remain president until 2001. Shapiro would continue to increase the endowment, expand academic programs, raise student diversity, and oversee the most renovations in Princeton's history. One of Shapiro's initiatives was the formation of the multidisciplinary Princeton Environmental Institute in 1994, renamed
3040-452: A nearby compass needle to move. At the time of discovery, Ørsted did not suggest any satisfactory explanation of the phenomenon, nor did he try to represent the phenomenon in a mathematical framework. However, three months later he began more intensive investigations. Soon thereafter he published his findings, proving that an electric current produces a magnetic field as it flows through a wire.

12160-412: The armed forces, with 151 dying during the war. After the war, enrollment spiked and the trustees established the system of selective admission in 1922. From the 1920s to the 1930s, the student body featured many students from preparatory schools, zero Black students, and dwindling Jewish enrollment because of quotas. Aside from managing Princeton during WWI, Hibben introduced the senior thesis in 1923 as
12320-445: The arts, science and engineering, social analysis, cultural difference, epistemology and cognition, ethical thought and moral values, historical analysis, and quantitative and computational reasoning; they must also have satisfactory ability in a foreign language. Additionally, they must complete two papers of independent work during their junior year—known as the junior papers—and craft a senior thesis to graduate; both revolve around
12480-574: The astronomer Angelo Secchi who extended it, but with some question as to whether Henry was given proper credit for his earlier work. In late 1861 and early 1862, during the American Civil War , Henry oversaw a series of lectures by prominent abolitionists at the Smithsonian Institution. Speakers included white clergymen, politicians, and activists such as Wendell Phillips , Horace Greeley , Henry Ward Beecher , and Ralph Waldo Emerson . Orator and former fugitive slave Frederick Douglass
12640-628: The basis of life . Meanwhile, magnetic interactions between the spin and angular momentum magnetic moments of electrons also play a role in chemical reactivity; such relationships are studied in spin chemistry . Electromagnetism also plays several crucial roles in modern technology : electrical energy production, transformation and distribution; light, heat, and sound production and detection; fiber optic and wireless communication; sensors; computation; electrolysis; electroplating; and mechanical motors and actuators. Electromagnetism has been studied since ancient times. Many ancient civilizations, including
12800-574: The board of trustees and dissatisfaction with his administration, he was forced to resign in 1902. Following Patton's resignation, Woodrow Wilson , an alumnus and popular professor, was elected the 13th president of the university. Noticing falling academic standards, Wilson orchestrated significant changes to the curriculum, where freshman and sophomores followed a unified curriculum while juniors and seniors concentrated study in one discipline. Ambitious seniors were allowed to undertake independent work, which would eventually shape Princeton's emphasis on
12960-648: The campus R.O.T.C. chapter in a game of touch football . As the years went on, the protests' agenda broadened to investments in South Africa, environmental issues, and women's rights. In response to these broadening protests, the Council of the Princeton University Community (CPUC) was founded to serve as a method for greater student voice in governance. Activism culminated in 1970 with a student, faculty, and staff member strike , so
13120-494: The cannon was returned to Princeton and placed at the eastern end of town. Two years later, it was moved to the campus under cover of night by Princeton students, and in 1840, it was buried in its current location. A second "Little Cannon" is buried in the lawn in front of nearby Whig Hall. The cannon, which may also have been captured in the Battle of Princeton, was stolen by students of Rutgers University in 1875. The theft ignited
13280-403: The certificates effectively serve as one. Course structure is determined by the instructor and department. Classes vary in their format, ranging from small seminars to medium-sized lecture courses to large lecture courses. The latter two typically have precepts , which are extra weekly discussion sessions that are led by either the professor or a graduate student. The average class meeting time
13440-592: The college became the site for the Battle of Princeton . During the battle, British soldiers briefly occupied Nassau Hall before eventually surrendering to American forces led by General George Washington . During the summer and fall of 1783, the Continental Congress and Washington met in Nassau Hall, making Princeton the country's capital for four months; Nassau Hall is where Congress learned of
13600-473: The college on preparing a new generation of both educated clergy and secular leadership in the new American nation. To this end, he tightened academic standards, broadened the curriculum, solicited investment for the college, and grew its size. A signatory of the Declaration of Independence , Witherspoon and his leadership led the college to becoming influential to the American Revolution . In 1777,
13760-473: The college's president in 1868, and lifted the institution out of a low period that had been brought about by the war. During his two decades of service, he overhauled the curriculum, oversaw an expansion of inquiry into the sciences, recruited distinguished faculty, and supervised the addition of a number of buildings in the High Victorian Gothic style to the campus. McCosh's tenure also saw
13920-628: The concentration they are pursuing. B.S.E. majors complete fewer courses in the humanities and social sciences and instead fulfill requirements in mathematics, physics, chemistry, and computer programming. They likewise must complete independent work, which typically involves a design project or senior thesis, but not the junior papers. A.B. majors must complete 31 courses, whereas B.S.E. majors must complete 36 courses. Students can choose from either 36 concentrations or create their own. They can also participate in 55 interdisciplinary certificate programs; since Princeton does not offer an academic minor ,
14080-460: The construction of two new buildings. In 1807, a large student riot occurred at Nassau Hall, spurred by underlying distrust of educational reforms by Smith away from the Church. Following Smith's mishandling of the situation, falling enrollment, and faculty resignations, the trustees of the university offered resignation to Smith, which he accepted. In 1812, Ashbel Green was unanimously elected by
14240-470: The court as of 2010 ) and numerous living industry and media tycoons and foreign heads of state are all counted among Princeton's alumni body. Princeton has graduated many members of the U.S. Congress and the U.S. Cabinet , including eight secretaries of state , three secretaries of defense and two chairmen of the Joint Chiefs of Staff . Princeton University, founded as the College of New Jersey,
14400-589: The creation and rise of many extracurricular activities, like the Princeton Glee Club , the Triangle Club , the first intercollegiate football team, and the first permanent eating club , as well as the elimination of fraternities and sororities. In 1879, Princeton conferred its first doctorates on James F. Williamson and William Libby, both members of the Class of 1877. Francis Patton took
14560-454: The creation of an office of sustainability, and investments into the sciences. Princeton's 20th and current president, Christopher Eisgruber , was elected in 2013. In 2017, Princeton University unveiled a large-scale public history and digital humanities investigation into its historical involvement with slavery called the Princeton & Slavery Project. The project saw the publication of hundreds of primary sources, 80 scholarly essays,
14720-502: The deep connections between electricity and magnetism that would be discovered over 2,000 years later. Despite all this investigation, ancient civilizations had no understanding of the mathematical basis of electromagnetism, and often analyzed its impacts through the lens of religion rather than science (lightning, for instance, was considered to be a creation of the gods in many cultures). Electricity and magnetism were originally considered to be two separate forces. This view changed with
14880-404: The dirty work of the laboratory. In his letters, Henry described Parker providing materials for experiments, fixing technical issues with Henry's equipment, and at times being used as a test subject in electrical experiments in which Henry and his students would shock Parker in classroom demonstrations. In 1842, when Parker fell ill, Henry's experiments stopped completely until he recovered. Henry
15040-662: The early Renaissance through the 19th century, with pieces by Monet , Cézanne , and Van Gogh , and features a growing collection of 20th-century and contemporary art, including paintings such as Andy Warhol 's Blue Marilyn. The museum features a collection of Chinese and Japanese art, with holdings in bronzes, tomb figurines, painting, and calligraphy , as well as collections of Korean, Southeast, and Central Asian art. Its collection of pre-Columbian art includes examples of Mayan and Olmec art, and its indigenous art ranges from Chile to Alaska to Greenland. The museum has collections of old master prints and drawings, and it has
15200-562: The effects of modern physics , including quantum mechanics and relativity . The theoretical implications of electromagnetism, particularly the requirement that observations remain consistent when viewed from various moving frames of reference ( relativistic electromagnetism ) and the establishment of the speed of light based on properties of the medium of propagation ( permeability and permittivity ), helped inspire Einstein's theory of special relativity in 1905. Quantum electrodynamics (QED) modifies Maxwell's equations to be consistent with
15360-603: The end of the 19th century, much of Princeton's architecture was designed by the Cope and Stewardson firm (led by the same University of Pennsylvania professors of architecture who designed a large part of Washington University in St. Louis and University of Pennsylvania ) resulting in the Collegiate Gothic style for which Princeton is known for today. Implemented initially by William Appleton Potter , and later enforced by
15520-648: The enrollment doubled. Hibben's successor, Harold Willis Dodds would lead the university through the Great Depression , World War II , and the Korean Conflict . With the Great Depression, many students were forced to withdraw due to financial reasons. At the same time, Princeton's reputation in physics and mathematics surged as many European scientists left for the United States due to uneasy tension caused by Nazi Germany . In 1930,
15680-576: The existence of a luminiferous aether through which the light propagates. However, subsequent experimental efforts failed to detect the presence of the aether. After important contributions of Hendrik Lorentz and Henri Poincaré , in 1905, Albert Einstein solved the problem with the introduction of special relativity, which replaced classical kinematics with a new theory of kinematics compatible with classical electromagnetism. (For more information, see History of special relativity .) In addition, relativity theory implies that in moving frames of reference,
15840-435: The existence of self-sustaining electromagnetic waves . Maxwell postulated that such waves make up visible light , which was later shown to be true. Gamma-rays, x-rays, ultraviolet, visible, infrared radiation, microwaves and radio waves were all determined to be electromagnetic radiation differing only in their range of frequencies. In the modern era, scientists continue to refine the theory of electromagnetism to account for
16000-507: The first half of the 20th century. Due to the tightening of academic standards, enrollment declined severely until 1907. In 1906, the reservoir Lake Carnegie was created by Andrew Carnegie , and the university officially became nonsectarian . Before leaving office, Wilson strengthened the science program to focus on "pure" research and broke the Presbyterian lock on the board of trustees. However, he did fail in winning support for
16160-408: The first time it is conclusively proved that telegrams can be sent with ease and certainty between the balloon and the quarters of the commanding officer. 5th. I feel assured, although I have not witnessed the experiment, that when the surface wind is from the east, as it was for several days last week, an observer in the balloon can be made to float nearly to the enemy's camp (as it is now situated to
16320-486: The following year in the Graduate School. In 1964, T'sai-ying Cheng became the first woman at Princeton to receive a Ph.D. In 1963, five women came to Princeton for one year to study "critical languages" as undergraduates, but were not candidates for a Princeton degree. Following abortive discussions with Sarah Lawrence College to relocate the women's college to Princeton and merge it with the university in 1967,
16480-516: The form of quantized , self-propagating oscillatory electromagnetic field disturbances called photons . Different frequencies of oscillation give rise to the different forms of electromagnetic radiation , from radio waves at the lowest frequencies, to visible light at intermediate frequencies, to gamma rays at the highest frequencies. Ørsted was not the only person to examine the relationship between electricity and magnetism. In 1802, Gian Domenico Romagnosi , an Italian legal scholar, deflected
16640-435: The formation and interaction of electromagnetic fields. This process culminated in the 1860s with the discovery of Maxwell's equations , a set of four partial differential equations which provide a complete description of classical electromagnetic fields. Maxwell's equations provided a sound mathematical basis for the relationships between electricity and magnetism that scientists had been exploring for centuries, and predicted
16800-639: The founding of a local chapter of Students for a Democratic Society (SDS) in 1965, which organized many of the later Princeton protests. In 1966, the SDS gained prominence on campus following picketing against a speech by President Lyndon B. Johnson , which gained frontpage coverage by the New York Times. A notable point of contention on campus was the Institute for Defense Analyses (IDA) and would feature multiple protests, some of which required police action. In 1967, SDS members and sympathizers beat
16960-410: The future as special cases, but does not plan to make general admissions of women graduate students." The student-run Daily Princetonian ran four articles about Meservey in one issue, including an editorial lamenting the potential "far reaching implications" of Meservey's admission which concluded: "Princeton is unique as an undergraduate men's college and must remain so." Eight more women enrolled
17120-494: The honor system was established, allowing for unproctored exams. In 1896, the college officially became a university, and as a result, it officially changed its name to Princeton University. In 1900, the Graduate School was formally established. Even with such accomplishments, Patton's administration remained lackluster with its administrative structure and towards its educational standards. Due to profile changes in
17280-469: The information I have gathered I am sure that important information may be obtained in regard to the topography of the country and to the position and movements of an enemy by means of the balloon now, and that Mr. Lowe is well qualified to render service in this way by the balloon now in his possession. 7th. The balloon which Mr. Lowe now has in Washington can only be inflated in a city where street gas
17440-474: The investment of the university's endowment, and oversees campus real estate and long-range physical planning. The trustees also exercise prior review and approval concerning changes in major policies such as those in instructional programs and admission as well as tuition and fees and the hiring of faculty members. The university is composed of the Undergraduate College, the Graduate School ,
17600-505: The jurisdiction of the Faculty-Student Committee on Discipline. Undergraduates are expected to sign a pledge on their written work affirming that they have not plagiarized the work. The first focus on issues of grade inflation by the Princeton administration began in 1998 when a university report was released showcasing a steady rise in undergraduate grades from 1973 to 1997. Subsequent reports and discussion from
17760-435: The knives took up the nails. On this the whole number was tried, and found to do the same, and that, to such a degree as to take up large nails, packing needles, and other iron things of considerable weight ... E. T. Whittaker suggested in 1910 that this particular event was responsible for lightning to be "credited with the power of magnetizing steel; and it was doubtless this which led Franklin in 1751 to attempt to magnetize
17920-478: The lack of magnetic monopoles , Abraham–Minkowski controversy , the location in space of the electromagnetic field energy, and the mechanism by which some organisms can sense electric and magnetic fields. The Maxwell equations are linear, in that a change in the sources (the charges and currents) results in a proportional change of the fields. Nonlinear dynamics can occur when electromagnetic fields couple to matter that follows nonlinear dynamical laws. This
18080-486: The lake's shore continues to serve as the headquarters for Princeton rowing. Princeton's grounds were designed by Beatrix Farrand between 1912 and 1943. Her contributions were most recently recognized with the naming of a courtyard for her. Subsequent changes to the landscape were introduced by Quennell Rothschild & Partners in 2000. In 2005, Michael Van Valkenburgh was hired as the new consulting landscape architect for Princeton's 2016 Campus Plan. Lynden B. Miller
18240-453: The land was converted to commercial and residential spaces. Robert Goheen would succeed Dodds by unanimous vote and serve as president until 1972. Goheen's presidency was characterized as being more liberal than previous presidents, and his presidency would see a rise in Black applicants, as well as the eventual coeducation of the university in 1969. During this period of rising diversity,
18400-490: The largest libraries in the colonies. In 1756, the college moved again to its present home in Princeton, New Jersey , because Newark was felt to be too close to New York. Princeton was chosen for its location in central New Jersey and by strong recommendation by Belcher. The college's home in Princeton was Nassau Hall , named for the royal William III of England , a member of the House of Orange-Nassau . The trustees of
18560-460: The largest university libraries in the world. Princeton uses a residential college system and is known for its eating clubs for juniors and seniors. The university has over 500 student organizations. Princeton students embrace a wide variety of traditions from both the past and present. The university is an NCAA Division I school and competes in the Ivy League. The school's athletic team,
18720-447: The library. In 1961, Princeton admitted its first female graduate student, Sabra Follett Meservey, who would go on to be the first woman to earn a master's degree at Princeton. Meservey was, at the time of her admission, already a member of the faculty at Douglass College within Princeton. The dean of the graduate school issued a statement clarifying that Meservey's admission was an exception, and that "Princeton may permit other women in
18880-427: The magnet rocker touching one of the two battery cells, causing a polarity change, and rocking the opposite direction until the other two leads hit the other battery. This apparatus allowed Henry to recognize the property of self inductance . British scientist Michael Faraday also recognized this property around the same time. Since Faraday published his results first, he became the officially recognized discoverer of
19040-442: The mechanisms behind these phenomena. The Greek philosopher Thales of Miletus discovered around 600 B.C.E. that amber could acquire an electric charge when it was rubbed with cloth, which allowed it to pick up light objects such as pieces of straw. Thales also experimented with the ability of magnetic rocks to attract one other, and hypothesized that this phenomenon might be connected to the attractive power of amber, foreshadowing
19200-429: The molecular scale, including its density, is determined by the balance between the electromagnetic force and the force generated by the exchange of momentum carried by the electrons themselves. In 1600, William Gilbert proposed, in his De Magnete , that electricity and magnetism, while both capable of causing attraction and repulsion of objects, were distinct effects. Mariners had noticed that lightning strikes had
19360-405: The morning of the 6th of June, I have examined the apparatus and witnessed the balloon experiments of Mr. Lowe, and have come to the following conclusions 1st. The balloon prepared by Mr. Lowe, inflated with ordinary street gas, will retain its charge for several days. 2d. In an inflated condition it can be towed by a few men along an ordinary road, or over fields, in ordinarily calm weather, from
19520-438: The new academic year starting September 2024 with administrators facing calls for resignation from faculty. Princeton explicitly prohibited the admission of women from its founding in 1746 until 1969. Since it lacked an affiliated women's college, it was often referred to as a "monastery", both lovingly and derisively, by members of the Princeton community. For about a decade, from 1887 to 1897, nearby Evelyn College for Women
19680-513: The next six months. He remained in the role until his death the following month. Upon his death, the academy dedicated a trust named the Joseph Henry Fund. As a public scientist and director of the Smithsonian Institution, Henry received visits from other scientists and inventors who sought his advice. Henry was patient, kindly, self-controlled, and gently humorous. One such visitor was Alexander Graham Bell , who on 1 March 1875 carried
19840-451: The objects. The effective forces generated by the momentum of electrons' movement is a necessary part of understanding atomic and intermolecular interactions. As electrons move between interacting atoms, they carry momentum with them. As a collection of electrons becomes more confined, their minimum momentum necessarily increases due to the Pauli exclusion principle . The behavior of matter at
20000-449: The office of the university president and other administrative offices. To the south of Nassau Hall lies a courtyard that is known as Cannon Green. Buried in the ground at the center is the "Big Cannon", which was left in Princeton by British troops as they fled following the Battle of Princeton. It remained in Princeton until the War of 1812 , when it was taken to New Brunswick . In 1836,
20160-496: The peace treaty between the colonies and the British. The college did suffer from the revolution, with a depreciated endowment and hefty repair bills for Nassau Hall. In 1795, President Samuel Stanhope Smith took office, the first alumnus to become president. Nassau Hall suffered a large fire that destroyed its interior in 1802, which Smith blamed on rebellious students. The college raised funds for reconstruction, as well as
20320-486: The permanent location of the Graduate School and the elimination of the eating clubs, which he proposed replacing with quadrangles, a precursor to the residential college system. Wilson also continued to keep Princeton closed off from accepting Black students. When an aspiring Black student wrote a letter to Wilson, he got his secretary to reply telling him to attend a university where he would be more welcome. John Grier Hibben became president in 1912, and would remain in
20480-439: The phenomenon. From 1832 to 1846, Henry served as the first Chair of Natural History at the College of New Jersey, which is now Princeton University . While in Princeton, he taught a wide range of courses including natural history , chemistry, and architecture, and ran a laboratory on campus. Decades later, Henry wrote that he made "several thousand original investigations on electricity, magnetism, and electro-magnetism" while on
20640-421: The places where it is galled [i.e. swelled or inflated] to another, twenty or more miles distant. 3d. It can be let up into the air by means of a rope in a calm day to a height sufficient to observe the country for twenty miles around and more, according to the degree of clearness of the atmosphere. The ascent may also be made at night and the camp lights of the enemy observed. 4th. From experiments made here for
20800-512: The post for two decades. On October 2, 1913, the Princeton University Graduate College was dedicated. When the United States entered World War I in 1917, Hibben allocated all available University resources to the government. As a result, military training schools opened on campus and laboratories and other facilities were used for research and operational programs. Overall, more than 6,000 students served in
20960-463: The practice for the future. Wilson further reformed the educational system by introducing the preceptorial system in 1905, a then-unique concept in the United States that augmented the standard lecture method of teaching with a more personal form in which small groups of students, or precepts, could interact with a single instructor, or preceptor, in their field of interest. The changes brought about many new faculty and cemented Princeton's academics for
21120-634: The predecessor of the university, the idea has been rebuked by Princeton historians. The founding of the university itself originated from a split in the Presbyterian church following the Great Awakening . In 1741, New Light Presbyterians were expelled from the Synod of Philadelphia in defense of how the Log College ordained ministers. The four founders of the College of New Jersey, who were New Lights, were either expelled or withdrew from
21280-408: The presidency in 1888, and although his election was not met by unanimous enthusiasm, he was well received by undergraduates. Patton's administration was marked by great change, for Princeton's enrollment and faculty had doubled. At the same time, the college underwent large expansion and social life was changing in reflection of the rise in eating clubs and burgeoning interest in athletics. In 1893,
21440-408: The publication of James Clerk Maxwell 's 1873 A Treatise on Electricity and Magnetism in which the interactions of positive and negative charges were shown to be mediated by one force. There are four main effects resulting from these interactions, all of which have been clearly demonstrated by experiments: In April 1820, Hans Christian Ørsted observed that an electrical current in a wire caused
21600-564: The report culminated to when in 2004, Nancy Weiss Malkiel , the dean of the college, implemented a grade deflation policy to address the findings. Malkiel's reason for the policy was that an A was becoming devalued as a larger percentage of the student body received one. Following its introduction, the number of A's and average GPA on campus dropped, although A's and B's were still the most frequent grades awarded. The policy received mixed approval from both faculty and students when first instituted. Criticism for grade deflation continued through
21760-410: The school was open to those of any religious denomination, with many of the founders being of Presbyterian faith, the college became the educational and religious capital of Scotch-Irish Presbyterian America. In 1747, following the death of then President Jonathan Dickinson, the college moved from Elizabeth to Newark, New Jersey , as that was where presidential successor Aaron Burr Sr. 's parsonage
21920-486: The strongest electromagnet at the time, for Yale . He also showed that, when making an electromagnet using just two electrodes attached to a battery, it is best to wind several coils of wire in parallel, but when using a set-up with multiple batteries, there should be only one single long coil. The latter made the telegraph feasible. Because of his early experiments in electromagnetism, some historians credit Henry with discoveries pre-dating Faraday and Hertz; however, Henry
22080-532: The trustees elected Jonathan Dickinson as president and opened in Elizabeth, New Jersey , where classes were held in Dickinson's parsonage . With its founding, it became the fourth-oldest institution of higher education in the United States, and one of nine colonial colleges chartered before the American Revolution . The founders aimed for the college to have an expansive curriculum to teach people of various professions, not solely ministerial work. Though
22240-483: The trustees of the college to become the eighth president. After the liberal tenure of Smith, Green represented the conservative "Old Side", in which he introduced rigorous disciplinary rules and heavily embraced religion. Even so, believing the college was not religious enough, he took a prominent role in establishing the Princeton Theological Seminary next door. While student riots were
22400-473: The university could become an "institution against expansion of the war." Princeton's protests would taper off later that year, with The Daily Princetonian saying that, "Princeton 1970–71 was an emotionally burned out university." In 1982, the residential college system was officially established under Goheen's successor William G. Bowen , who would serve until 1988. During his presidency, Princeton's endowment increased from $ 625 million to $ 2 billion, and
22560-644: The university through the American Civil War . When Nassau Hall burned down again in 1855, Maclean raised funds and used the money to rebuild Nassau Hall and run the university on an austerity budget during the war years. With a third of students from the college being from the South, enrollment fell. Once many of the Southerners left, the campus became a sharp proponent for the Union , even bestowing an honorary degree to President Lincoln . James McCosh became
22720-586: The university's supervising architect, Ralph Adams Cram , the Collegiate Gothic style remained the standard for all new building on the Princeton campus until 1960. A flurry of construction projects in the 1960s produced a number of new buildings on the south side of the main campus, many of which have been poorly received. Several prominent architects have contributed some more recent additions, including Frank Gehry (Lewis Library), I. M. Pei (Spelman Halls), Demetri Porphyrios ( Whitman College ,
22880-422: The university's supervising architect, designed the chapel, which he viewed as the crown jewel for the Collegiate Gothic motif he had championed for the campus. At the time of its construction, it was the second largest university chapel in the world, after King's College Chapel, Cambridge . It underwent a two-year, $ 10 million restoration campaign between 2000 and 2002. The Chapel seats around 2,000 and serves as
23040-556: The unveiling of the Joseph Henry statue in front of the Smithsonian Castle . Henry was a member of the United States Lighthouse Board from 1852 until his death. He was appointed chairman in 1871 and served in that position the remainder of his life. He was the only civilian to serve as chairman. The United States Coast Guard honored Henry for his work on lighthouses and fog signal acoustics by naming
23200-403: The west of us), or even to float over it, and then return eastward by rising to a higher elevation. This assumption is based on the fact that the upper strata of wind in this latitude is always flowing eastward. Mr. Lowe informs me, and I do not doubt his statement, that he will on any day which is favorable make an excursion of the kind above mentioned. 6th. From all the facts I have observed and
23360-584: The years after the war, with the construction of Firestone Library in 1948 and the establishment of the Forrestal Research Center in nearby Plainsboro Township in the 1950s. Government sponsored research increased sharply, particularly in the physics and engineering departments, with much of it occurring at the new Forrestal campus. Though, as the years progressed, scientific research at the Forrestal campus declined, and in 1973, some of
23520-430: Was Nassau Hall, completed in 1756, and situated on the northern edge of the campus facing Nassau Street. The campus expanded steadily around Nassau Hall during the early and middle 19th century. The McCosh presidency (1868–88) saw the construction of a number of buildings in the High Victorian Gothic and Romanesque Revival styles, although many of them are now gone, leaving the remaining few to appear out of place. At
23680-406: Was an electromagnetic wave propagating in the luminiferous ether . In classical electromagnetism, the behavior of the electromagnetic field is described by a set of equations known as Maxwell's equations , and the electromagnetic force is given by the Lorentz force law . One of the peculiarities of classical electromagnetism is that it is difficult to reconcile with classical mechanics , but it
23840-522: Was appointed Professor of Mathematics and Natural Philosophy at The Albany Academy by Principal T. Romeyn Beck . Some of his most important research was conducted in this new position. His curiosity about terrestrial magnetism led him to experiment with magnetism in general. He was the first to coil insulated wire tightly around an iron core in order to make a more powerful electromagnet, improving on William Sturgeon 's electromagnet which used loosely coiled uninsulated wire. Using this technique, he built
24000-476: Was appointed the first Secretary of the Smithsonian Institution in 1846, and served in this capacity until 1878. In 1848, while Secretary, Henry worked in conjunction with Professor Stephen Alexander to determine the relative temperatures for different parts of the solar disk. They used a thermopile to determine that sunspots were cooler than the surrounding regions. This work was shown to
24160-611: Was given free tuition. Even with free tuition, he was so poor that he had to support himself with teaching and private tutoring positions. He intended to go into medicine, but in 1824 he was appointed an assistant engineer for the survey of the State road being constructed between the Hudson River and Lake Erie . From then on, he was inspired to a career in either civil or mechanical engineering . Henry excelled academically, even often helping his teachers teach science. In 1826, he
