Paul Corkum
Paul Bruce Corkum (born October 30, 1943) is a Canadian physicist specializing in attosecond physics and laser science., as published in '' Physics in Canada'', 65(2) 58. He holds a joint University of Ottawa– NRC chair in Attosecond Photonics. He is one of the students of strong field atomic physics, ''i.e.'' atoms and plasmas in super-intense laser fields. Biography and research Corkum was born in Saint John, New Brunswick. He obtained his BSc (1965) from Acadia University, Nova Scotia, and his MSc (1967) and PhD (1972) in theoretical physics from Lehigh University, Pennsylvania. He won several awards for his work on laser science. Corkum is both a theorist and an experimentalist. In the 1980s he developed a model of the ionization of atoms (''i.e.'' plasma production) and on this basis proposed a new approach to making X-ray lasers (Optical field Ionization, OFI). OFI lasers are today one of the most important developments in X-ray laser research. In the early 1990s in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Saint John, New Brunswick
Saint John is a seaport city of the Atlantic Ocean located on the Bay of Fundy in the province of New Brunswick, Canada. Saint John is the oldest incorporated city in Canada, established by royal charter on May 18, 1785, during the reign of King George III. The port is Canada's third-largest port by tonnage with a cargo base that includes dry and liquid bulk, Breakbulk_cargo, break bulk, containers, and cruise. The city was the most populous in New Brunswick until the 2016 census, when it was overtaken by Moncton. It is currently the second-largest city in the province, with a population of 69,895 over an area of . French explorer Samuel de Champlain landed at Saint John Harbour on June 24, 1604 (the feast of St. John the Baptist) and is where the Saint John River (Bay of Fundy), Saint John River gets its name although Mi'kmaq and Maliseet, Wolastoqiyik peoples lived in the region for thousands of years prior calling the river Wolastoq.

Theoretical Physics
Theoretical physics is a branch of physics that employs mathematical models and abstractions of physical objects and systems to rationalize, explain and predict natural phenomena. This is in contrast to experimental physics, which uses experimental tools to probe these phenomena. The advancement of science generally depends on the interplay between experimental studies and theory. In some cases, theoretical physics adheres to standards of mathematical rigour while giving little weight to experiments and observations.There is some debate as to whether or not theoretical physics uses mathematics to build intuition and illustrativeness to extract physical insight (especially when normal experience fails), rather than as a tool in formalizing theories. This links to the question of it using mathematics in a less formally rigorous, and more intuitive or heuristic way than, say, mathematical physics. For example, while developing special relativity, Albert Einstein was concerned wit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Royal Medal
The Royal Medal, also known as The Queen's Medal and The King's Medal (depending on the gender of the monarch at the time of the award), is a silver-gilt medal, of which three are awarded each year by the Royal Society, two for "the most important contributions to the advancement of natural knowledge" and one for "distinguished contributions in the applied sciences", done within the Commonwealth of Nations. Background The award was created by George IV of the United Kingdom, George IV and awarded first during 1826. Initially there were two medals awarded, both for the most important discovery within the year previous, a time period which was lengthened to five years and then shortened to three. The format was endorsed by William IV of the United Kingdom, William IV and Victoria of the United Kingdom, Victoria, who had the conditions changed during 1837 so that mathematics was a subject for which a Royal Medal could be awarded, albeit only every third year. The conditions were chang ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

The Willis E
''The'' () is a grammatical article in English, denoting persons or things that are already or about to be mentioned, under discussion, implied or otherwise presumed familiar to listeners, readers, or speakers. It is the definite article in English. ''The'' is the most frequently used word in the English language; studies and analyses of texts have found it to account for seven percent of all printed English-language words. It is derived from gendered articles in Old English which combined in Middle English and now has a single form used with nouns of any gender. The word can be used with both singular and plural nouns, and with a noun that starts with any letter. This is different from many other languages, which have different forms of the definite article for different genders or numbers. Pronunciation In most dialects, "the" is pronounced as (with the voiced dental fricative followed by a schwa) when followed by a consonant sound, and as (homophone of the archaic pron ...

Wolf Prize In Physics
The Wolf Prize in Physics is awarded once a year by the Wolf Foundation in Israel. It is one of the six Wolf Prizes established by the Foundation and awarded since 1978; the others are in Agriculture, Chemistry, Mathematics, Medicine and Arts. The Wolf Prizes in physics and chemistry are often considered the second most prestigious awards in those fields, after the Nobel Prize.Basolo, F: ''From Coello to Inorganic Chemistry: A Lifetime of Reactions'', page 65, Springer, 2002 The prize in physics has gained a reputation for identifying future winners of the Nobel Prize – from the 26 prizes awarded between 1978 and 2010, fourteen winners have gone on to win the Nobel Prize, five of those in the following year.

Electrons
The electron ( or ) is a subatomic particle with a negative one elementary electric charge. Electrons belong to the first generation of the lepton particle family, and are generally thought to be elementary particles because they have no known components or substructure. The electron's mass is approximately 1/1836 that of the proton. Quantum mechanical properties of the electron include an intrinsic angular momentum ( spin) of a half-integer value, expressed in units of the reduced Planck constant, . Being fermions, no two electrons can occupy the same quantum state, in accordance with the Pauli exclusion principle. Like all elementary particles, electrons exhibit properties of both particles and waves: They can collide with other particles and can be diffracted like light. The wave properties of electrons are easier to observe with experiments than those of other particles like neutrons and protons because electrons have a lower mass and hence a longer de Broglie wav ...

Molecular Orbital
In chemistry, a molecular orbital is a mathematical function describing the location and wave-like behavior of an electron in a molecule. This function can be used to calculate chemical and physical properties such as the probability of finding an electron in any specific region. The terms ''atomic orbital'' and ''molecular orbital'' were introduced by Robert S. Mulliken in 1932 to mean ''one-electron orbital wave functions''. At an elementary level, they are used to describe the ''region'' of space in which a function has a significant amplitude. In an isolated atom, the orbital electrons' location is determined by functions called atomic orbitals. When multiple atoms combine chemically into a molecule, the electrons' locations are determined by the molecule as a whole, so the atomic orbitals combine to form molecular orbitals. The electrons from the constituent atoms occupy the molecular orbitals. Mathematically, molecular orbitals are an approximate solution to the Schrödin ...
