Ishfaq Ahmad
Ishfaq Ahmad Khan (3 November 1930 – 18 January 2018) , was a Pakistani nuclear physicist, emeritus professor of high-energy physics at the National Centre for Physics, and former science advisor to the Government of Pakistan. A versatile theoretical physicist, Ahmad made significant contributions in the theoretical development of the applications and concepts involving the particle physics, and its relative extension to the quantum electrodynamics, while working as senior research scientist at the CERN in 1960s and 1970s. Joining the PAEC in late 1950s, Ahmad served as the director of the Nuclear Physics Division at the secret Pinstech Institute which developed the first designs of atomic bombs, a clandestine project during the post-1971 war. There, he played an influential role in leading the physics and mathematical calculations in the critical mass of the weapons, and did theoretical work on the implosion method used in the weapons. Since 1960s and onwards, he has ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Professor Emeritus
''Emeritus'' (; female: ''emerita'') is an adjective used to designate a retired chair, professor, pastor, bishop, pope, director, president, prime minister, rabbi, emperor, or other person who has been "permitted to retain as an honorary title the rank of the last office held". In some cases, the term is conferred automatically upon all persons who retire at a given rank, but in others, it remains a mark of distinguished service awarded selectively on retirement. It is also used when a person of distinction in a profession retires or hands over the position, enabling their former rank to be retained in their title, e.g., "professor emeritus". The term ''emeritus'' does not necessarily signify that a person has relinquished all the duties of their former position, and they may continue to exercise some of them. In the description of deceased professors emeritus listed at U.S. universities, the title ''emeritus'' is replaced by indicating the years of their appointmentsThe Proto ...

Nuclear Physicist
Nuclear physics is the field of physics that studies atomic nuclei and their constituents and interactions, in addition to the study of other forms of nuclear matter. Nuclear physics should not be confused with atomic physics, which studies the atom as a whole, including its electrons. Discoveries in nuclear physics have led to applications in many fields. This includes nuclear power, nuclear weapons, nuclear medicine and magnetic resonance imaging, industrial and agricultural isotopes, ion implantation in materials engineering, and radiocarbon dating in geology and archaeology. Such applications are studied in the field of nuclear engineering. Particle physics evolved out of nuclear physics and the two fields are typically taught in close association. Nuclear astrophysics, the application of nuclear physics to astrophysics, is crucial in explaining the inner workings of stars and the origin of the chemical elements.

Pakistani People
Pakistanis ( ur, , translit=Pākistānī Qaum, ) are the citizens and nationals of the Islamic Republic of Pakistan. According to the 2017 Pakistani national census, the population of Pakistan stood at over 213 million people, making it the world's fifth-most populous country. The majority of Pakistanis natively speak languages belonging to the Indo-Iranic family ( Indo-Aryan and Iranic subfamilies). Located in South Asia, the country is also the source of a significantly large diaspora, most of whom reside in the Arab countries of the Persian Gulf, with an estimated population of 4.7 million. The second-largest Pakistani diaspora resides throughout both Northwestern Europe and Western Europe, where there are an estimated 2.4 million; over half of this figure reside in the United Kingdom (see British Pakistanis). Ethnic subgroups Having one of the fastest-growing populations in the world, Pakistan's people belong to various ethnic groups, with the overwhelming majorit ...

Nishan-i-Imitiaz
The Nishan-e-Imtiaz (; ) is one of the state organized civil decorations of Pakistan. It is awarded for achievements towards world recognition for Pakistan or outstanding service for the country. However, the award is not limited to citizens of Pakistan and, while it is a civilian award, it can also be awarded to military personnel and worn on the uniform. Nishan, translating as decoration/order/mark, is a highly restricted and prestigious award, roughly equivalent to Presidential Medal of Freedom (United States) and Order of the British Empire (United Kingdom), and is the first category award of Order of Imtiaz. The other three descending categories are Hilal-i-Imtiaz, Sitara-i-Imtiaz and Tamgha-e-Imtiaz. Usually, it is regarded as the highest award one can achieve in Pakistan since the higher award Nishan-e-Pakistan is awarded only to foreign Heads of States. The Nishan-e-Imtiaz was established on 19 March 1957, following the proclamation of Pakistan as a parliamentary repub ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Stellar Nucleosynthesis
Stellar nucleosynthesis is the creation (nucleosynthesis) of chemical elements by nuclear fusion reactions within stars. Stellar nucleosynthesis has occurred since the original creation of hydrogen, helium and lithium during the Big Bang. As a predictive theory, it yields accurate estimates of the observed abundances of the elements. It explains why the observed abundances of elements change over time and why some elements and their isotopes are much more abundant than others. The theory was initially proposed by Fred Hoyle in 1946, who later refined it in 1954. Further advances were made, especially to nucleosynthesis by neutron capture of the elements heavier than iron, by Margaret and Geoffrey Burbidge, William Alfred Fowler and Hoyle in their famous 1957 B2FH paper, which became one of the most heavily cited papers in astrophysics history. Stars evolve because of changes in their composition (the abundance of their constituent elements) over their lifespans, first ...

Pion
In particle physics, a pion (or a pi meson, denoted with the Greek letter pi: ) is any of three subatomic particles: , , and . Each pion consists of a quark and an antiquark and is therefore a meson. Pions are the lightest mesons and, more generally, the lightest hadrons. They are unstable, with the charged pions and decaying after a mean lifetime of 26.033 nanoseconds ( seconds), and the neutral pion decaying after a much shorter lifetime of 85 attoseconds ( seconds). Charged pions most often decay into muons and muon neutrinos, while neutral pions generally decay into gamma rays. The exchange of virtual pions, along with vector, rho and omega mesons, provides an explanation for the residual strong force between nucleons. Pions are not produced in radioactive decay, but commonly are in high-energy collisions between hadrons. Pions also result from some matter–antimatter annihilation events. All types of pions are also produced in natural processes ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
