Ferdinand Hassler
Ferdinand Rudolph Hassler (October 6, 1770 – November 20, 1843) was a Swiss-American surveyor who is considered the forefather of both the National Oceanic and Atmospheric Administration (NOAA) and the National Institute of Standards and Technology (NIST) for his achievements as the first Superintendent of the U.S. Survey of the Coast and the first U.S. Superintendent of Weights and Measures. Early life and education Hassler was born on October 6, 1770 in Aarau, Switzerland. He was the son of Magdalena Ernst and Hans Jakob Hassler, a prosperous watchmaker and local official. He attended the Latin school and an advanced private school, then in 1786 the institute that later became the University of Bern. At first he studied law, but became a student of Johann Georg Tralles and changed his academic focus to astronomy, mathematics and physics. From 1791 to 1797 he continued his studies in France and Germany. In the summer of 1793, he studied under scientists Jean-Charles de Bo ...

American Philosophical Society
The American Philosophical Society (APS), founded in 1743 in Philadelphia, is a scholarly organization that promotes knowledge in the sciences and humanities through research, professional meetings, publications, library resources, and community outreach. Considered the first learned society in the United States, it has about 1,000 elected members, and by April 2020 had had only 5,710 members since its creation. Through research grants, published journals, the American Philosophical Society Museum, an extensive library, and regular meetings, the society supports a variety of disciplines in the humanities and the sciences. Philosophical Hall, now a museum, is just east of Independence Hall in Independence National Historical Park; it was designated a National Historic Landmark in 1965. History The Philosophical Society, as it was originally called, was founded in 1743 by Benjamin Franklin, James Alexander, Francis Hopkinson, John Bartram, Philip Syng, Jr. and others as ...

French Geodesic Mission To The Equator
The French Geodesic Mission to the Equator (french: Expédition géodésique française en Équateur, also called the French Geodesic Mission to Peru and the Spanish-French Geodesic Mission) was an 18th-century expedition to what is now Ecuador carried out for the purpose of performing an arc measurement, measuring the length of a degree of latitude near the Equator, by which the Earth radius can be inferred. The mission was one of the first geodesic (or ''geodetic'') missions carried out under modern scientific principles, and the first major international scientific expedition. Background In the 18th century, there was significant debate in the scientific community, specifically in the French Academy of Sciences (''Académie des sciences''), as to whether the circumference of the Earth was greater around the Equator or around the poles. French astronomer Jacques Cassini held to the view that the polar circumference was greater. Louis XV, the King of France and the academy ...

Paris Meridian
The Paris meridian is a meridian line running through the Paris Observatory in Paris, France – now longitude 2°20′14.02500″ East. It was a long-standing rival to the Greenwich meridian as the prime meridian of the world. The "Paris meridian arc" or "French meridian arc" (French: ''la Méridienne de France'') is the name of the meridian arc measured along the Paris meridian. The French meridian arc was important for French cartography, inasmuch as the triangulations of France began with the measurement of the French meridian arc. Moreover, the French meridian arc was important for geodesy as it was one of the meridian arcs which were measured to determine the figure of the Earth via the arc measurement method. The determination of the figure of the Earth was a problem of the highest importance in astronomy, inasmuch as the diameter of the Earth was the unit to which all celestial distances had to be referred. History French cartography and the figure of the Ear ...

Mètre Des Archives
The history of the metre starts with the Scientific Revolution that is considered to have begun with Nicolaus Copernicus's publication of ''De revolutionibus orbium coelestium'' in 1543. Increasingly accurate measurements were required, and scientists looked for measures that were universal and could be based on natural phenomena rather than royal decree or physical prototypes. Rather than the various complex systems of subdivision then in use, they also preferred a decimal system to ease their calculations. With the French Revolution (1789) came a desire to replace many features of the Ancien Régime, including the traditional units of measure. As a base unit of length, many scientists had favoured the seconds pendulum (a pendulum with a half-period of one second) one century earlier, but this was rejected as it had been discovered that this length varied from place to place with local gravity. A new unit of length, the ''metre'' was introduced – defined as one ten-milliont ...

James Madison
James Madison Jr. (March 16, 1751June 28, 1836) was an American statesman, diplomat, and Founding Father. He served as the fourth president of the United States from 1809 to 1817. Madison is hailed as the "Father of the Constitution" for his pivotal role in drafting and promoting the Constitution of the United States and the Bill of Rights. Madison was born into a prominent slave-owning planter family in Virginia. He served as a member of the Virginia House of Delegates and the Continental Congress during and after the American Revolutionary War. Unsatisfied with the weak national government established by the Articles of Confederation, he helped organize the Constitutional Convention, which produced a new constitution. Madison's Virginia Plan was the basis for the Convention's deliberations, and he was an influential voice at the convention. He became one of the leaders in the movement to ratify the Constitution, and joined Alexander Hamilton and John Jay in writi ...

An Act of Congress is a statute enacted by the United States Congress. Acts may apply only to individual entities (called private laws), or to the general public ( public laws). For a bill to become an act, the text must pass through both houses with a majority, then be either signed into law by the president of the United States, be left unsigned for ten days (excluding Sundays) while Congress remains in session, or, if vetoed by the president, receive a congressional override from of both houses. Public law, private law, designation In the United States, Acts of Congress are designated as either public laws, relating to the general public, or private laws, relating to specific institutions or individuals.

Union College
Union College is a private liberal arts college in Schenectady, New York. Founded in 1795, it was the first institution of higher learning chartered by the New York State Board of Regents, and second in the state of New York, after Columbia College (formerly King's College). In the 19th century, it became known as the " Mother of Fraternities",Somers (2003), p. 304 as three of the earliest Greek letter societies were established there. The school was once referred to as one of the " Big Four" alongside Harvard University, Yale University and Princeton University, before the Civil War and a financial scandal led to its fall from grace and the top national rankings. Union began enrolling women in 1970, after 175 years as an all-male institution. The college offers a liberal arts curriculum across 21 academic departments, as well as opportunities for interdepartmental majors and self-designed organizing theme majors. It offers a wide array of courses in the humanities, social ...

United States Secretary Of War
The secretary of war was a member of the U.S. president's Cabinet, beginning with George Washington's administration. A similar position, called either "Secretary at War" or "Secretary of War", had been appointed to serve the Congress of the Confederation under the Articles of Confederation between 1781 and 1789. Benjamin Lincoln and later Henry Knox held the position. When Washington was inaugurated as the first President under the Constitution, he appointed Knox to continue serving as Secretary of War. The secretary of war was the head of the War Department. At first, he was responsible for all military affairs, including naval affairs. In 1798, the secretary of the Navy was created by statute, and the scope of responsibility for this office was reduced to the affairs of the United States Army. From 1886 onward, the secretary of war was in the line of succession to the presidency, after the vice president of the United States, the Speaker of the House of Representative ...
