Theodore William Richards
Theodore William Richards (January 31, 1868 – April 2, 1928) was the first American scientist to receive the Nobel Prize in Chemistry, earning the award "in recognition of his exact determinations of the atomic weights of a large number of the chemical elements." Biography Theodore Richards was born in Germantown, Philadelphia, Germantown, Pennsylvania, to William Trost Richards, a land- and seascape painter, and Anna Matlack Richards, a poet. Richards received most of his pre-college education from his mother. During one summer's stay at Newport, Rhode Island, Richards met Professor Josiah Parsons Cooke of Harvard, who showed the young boy Saturn's rings through a small telescope. Years later Cooke and Richards would work together in Cooke's laboratory. Beginning in 1878, the Richards family spent two years in Europe, largely in England, where Theodore Richards' scientific interests grew stronger. After the family's return to the United States, he entered Haverford Coll ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Germantown, Philadelphia, Pennsylvania
Germantown ( Pennsylvania Dutch: ''Deitscheschteddel'') is an area in Northwest Philadelphia. Founded by German, Quaker, and Mennonite families in 1683 as an independent borough, it was absorbed into Philadelphia in 1854. The area, which is about six miles northwest from the city center, now consists of two neighborhoods: 'Germantown' and 'East Germantown'. Germantown has played a significant role in American history; it was the birthplace of the American antislavery movement, the site of a Revolutionary War battle, the temporary residence of George Washington, the location of the first bank of the United States, and the residence of many notable politicians, scholars, artists, and social activists. Today the area remains rich in historic sites and buildings from the colonial era, some of which are open to the public. Boundaries Germantown stretches for about two miles along Germantown Avenue northwest from Windrim and Roberts Avenues. Germantown has been consistently boun ...

Davy Medal
The Davy Medal is awarded by the Royal Society of London "for an outstandingly important recent discovery in any branch of chemistry". Named after Humphry Davy, the medal is awarded with a monetary gift, initially of £1000 (currently £2000). History The medal was first awarded in 1877 to Robert Wilhelm Bunsen and Gustav Robert Kirchhoff "for their researches & discoveries in spectrum analysis", and has since been awarded 140 times. The medal is awarded annually and, unlike other Royal Society medals (such as the Hughes), has been awarded without interruption since its inception. The medal has been awarded to multiple individuals in the same year: in 1882, for example, it was awarded to Dmitri Mendeleev and Julius Lothar Meyer "for their discovery of the periodic relations of the atomic weights"; in 1883 to Marcellin Berthelot and Julius Thomsen "for their researches in thermo-chemistry"; in 1893 to Jacobus Henricus van 't Hoff and Joseph Achille Le Bel "In recognition of thei ...

Saturn's Rings
The rings of Saturn are the most extensive ring system of any planet in the Solar System. They consist of countless small particles, ranging in size from micrometers to meters, that orbit around Saturn. The ring particles are made almost entirely of water ice, with a trace component of rocky material. There is still no consensus as to their mechanism of formation. Although theoretical models indicated that the rings were likely to have formed early in the Solar System's history, newer data from '' Cassini'' suggested they formed relatively late. Although reflection from the rings increases Saturn's brightness, they are not visible from Earth with unaided vision. In 1610, the year after Galileo Galilei turned a telescope to the sky, he became the first person to observe Saturn's rings, though he could not see them well enough to discern their true nature. In 1655, Christiaan Huygens was the first person to describe them as a disk surrounding Saturn. The concept that Saturn's rin ...

Harvard
Harvard University is a private Ivy League research university in Cambridge, Massachusetts. Founded in 1636 as Harvard College and named for its first benefactor, the Puritan clergyman John Harvard, it is the oldest institution of higher learning in the United States and one of the most prestigious and highly ranked universities in the world. The university is composed of ten academic faculties plus Harvard Radcliffe Institute. The Faculty of Arts and Sciences offers study in a wide range of undergraduate and graduate academic disciplines, and other faculties offer only graduate degrees, including professional degrees. Harvard has three main campuses: the Cambridge campus centered on Harvard Yard; an adjoining campus immediately across Charles River in the Allston neighborhood of Boston; and the medical campus in Boston's Longwood Medical Area. Harvard's endowment is valued at $50.9 billion, making it the wealthiest academic institution in the world. Endowment inco ...

Anna Matlack Richards
Anna Matlack Richards (1834–1900) was a 19th-century American children's author, poet and translator best known for her fantasy novel, '' A New Alice in the Old Wonderland''. Biography Anna Matlack was raised in a prominent intellectual Quaker family in Philadelphia, Pennsylvania. As a young woman she published fictional works, plays, and poems, including a fictional autobiography as by "Mrs. A. M. Richards" entitled ''Memories of a Grandmother'' in 1854. In 1856 she married landscape and maritime painter William Trost Richards. They traveled abroad frequently and lived in Cornwall, England, from 1878 to 1880. The couple had eight children, only five of whom lived past infancy. Matlack educated the children at home to a pre-college level in the arts and sciences. One of the couple's sons, Theodore William Richards, would later win the 1914 Nobel Prize in Chemistry. Anna Richards Brewster, their sixth child, went on to become an important painter in her own right, having recei ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
William Trost Richards
William Trost Richards (November 14, 1833 – November 8, 1905) was an American landscape artist. He was associated with both the Hudson River School and the American Pre-Raphaelite movement.

Chemical Element
A chemical element is a species of atoms that have a given number of protons in their nuclei, including the pure substance consisting only of that species. Unlike chemical compounds, chemical elements cannot be broken down into simpler substances by any chemical reaction. The number of protons in the nucleus is the defining property of an element, and is referred to as its atomic number (represented by the symbol ''Z'') – all atoms with the same atomic number are atoms of the same element. Almost all of the baryonic matter of the universe is composed of chemical elements (among rare exceptions are neutron stars). When different elements undergo chemical reactions, atoms are rearranged into new compounds held together by chemical bonds. Only a minority of elements, such as silver and gold, are found uncombined as relatively pure native element minerals. Nearly all other naturally occurring elements occur in the Earth as compounds or mixtures. Air is primarily a mixture o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Atomic Weight
Relative atomic mass (symbol: ''A''; sometimes abbreviated RAM or r.a.m.), also known by the deprecated synonym atomic weight, is a dimensionless physical quantity defined as the ratio of the average mass of atoms of a chemical element in a given sample to the atomic mass constant. The atomic mass constant (symbol: ''m'') is defined as being of the mass of a carbon-12 atom. Since both quantities in the ratio are masses, the resulting value is dimensionless; hence the value is said to be ''relative''. For a single given sample, the relative atomic mass of a given element is the weighted arithmetic mean of the masses of the individual atoms (including their isotopes) that are present in the sample. This quantity can vary substantially between samples because the sample's origin (and therefore its radioactive history or diffusion history) may have produced unique combinations of isotopic abundances. For example, due to a different mixture of stable carbon-12 and carbon-13 isoto ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
