Albert Einstein
Albert Einstein (14 March 187918 April 1955) was a German-born theoretical physicist who is best known for developing the theory of relativity. Einstein also made important contributions to quantum mechanics. His mass–energy equivalence formula , which arises from special relativity, has been called "the world's most famous equation". He received the 1921 Nobel Prize in Physics for . Born in the German Empire, Einstein moved to Switzerland in 1895, forsaking his German citizenship (as a subject of the Kingdom of Württemberg) the following year. In 1897, at the age of seventeen, he enrolled in the mathematics and physics teaching diploma program at the Swiss ETH Zurich, federal polytechnic school in Zurich, graduating in 1900. He acquired Swiss citizenship a year later, which he kept for the rest of his life, and afterwards secured a permanent position at the Swiss Patent Office in Bern. In 1905, he submitted a successful PhD dissertation to the University of Zurich. In 19 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Nishan-i-Imtiaz
The Nishan-e-Imtiaz (; ) is one of the state organized Civil decorations of Pakistan, 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 Pak ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fellow Of The Pakistan Academy Of Sciences
The Pakistan Academy of Sciences () (abbreviated as: PAS), is a learned society of sciences, which described itself as "a repository of the highest scientific talent available in the country." Established in 1953 in Lahore, Punjab, the academy acts as a consultative forum and scientific advisor to the Pakistan government on important aspects on the affairs of all forms of science– the social and physical sciences. Regulating affairs of by its Charter and laws approved by the fellows, the academy is governed by a council that is chaired by its President. Due to its utmost importance, the fellowship of the academy is extremely restricted, only to the scholars of the high merit who have made outstanding contributions to the advancement of scientific knowledge. History The idea of establishing the academy was mooted in November 1947 when the first national education conference was organized by the Ministry of Education in Karachi, Sindh, which was inaugurated Muhammad Ali Jin ...

Pakistan And Weapons Of Mass Destruction
Pakistan is one of List of states with nuclear weapons, nine states that possess nuclear weapons, and is not party to the Nuclear Non-Profileration Treaty (NPT) and any of its provisions. As of 2025, multiple unofficial sources indicate a stockpile of 170 warheads (fission type). Pakistan maintains a doctrine of Full spectrum deterrence, minimum credible deterrence instead of a no first-use policy, promising to use "any weapon in its arsenal" to protect its interests in case of an aggressive attack. Pakistan is not widely suspected of either producing biological weapons or having an offensive biological programme. Pakistan has ratified the Geneva Protocol, the Chemical Weapons Convention, as well as the Biological Weapons Convention, Biological and Toxin Weapons Convention). History After the Partition of India in 1947, India and Pakistan have been in conflict over several issues, including the disputed territory of Jammu and Kashmir (union territory), Jammu and Kashmir. ...

Paramagnetism
Paramagnetism is a form of magnetism whereby some materials are weakly attracted by an externally applied magnetic field, and form internal, induced magnetic fields in the direction of the applied magnetic field. In contrast with this behavior, diamagnetic materials are repelled by magnetic fields and form induced magnetic fields in the direction opposite to that of the applied magnetic field. Paramagnetic materials include most chemical elements and some compounds; they have a relative magnetic permeability slightly greater than 1 (i.e., a small positive magnetic susceptibility) and hence are attracted to magnetic fields. The magnetic moment induced by the applied field is linear in the field strength and rather weak. It typically requires a sensitive analytical balance to detect the effect and modern measurements on paramagnetic materials are often conducted with a SQUID magnetometer. Paramagnetism is due to the presence of unpaired electrons in the material, so most atom ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nuclear Space
In mathematics, nuclear spaces are topological vector spaces that can be viewed as a generalization of finite-dimensional Euclidean spaces and share many of their desirable properties. Nuclear spaces are however quite different from Hilbert spaces, another generalization of finite-dimensional Euclidean spaces. They were introduced by Alexander Grothendieck. The topology on nuclear spaces can be defined by a family of seminorms whose unit balls decrease rapidly in size. Vector spaces whose elements are "smooth" in some sense tend to be nuclear spaces; a typical example of a nuclear space is the set of smooth functions on a compact manifold. All finite-dimensional vector spaces are nuclear. There are no Banach spaces that are nuclear, except for the finite-dimensional ones. In practice a sort of converse to this is often true: if a "naturally occurring" topological vector space is a Banach space, then there is a good chance that it is nuclear.

C*-algebra
In mathematics, specifically in functional analysis, a C∗-algebra (pronounced "C-star") is a Banach algebra together with an involution satisfying the properties of the adjoint. A particular case is that of a complex algebra ''A'' of continuous linear operators on a complex Hilbert space with two additional properties: * ''A'' is a topologically closed set in the norm topology of operators. * ''A'' is closed under the operation of taking adjoints of operators. Another important class of non-Hilbert C*-algebras includes the algebra C_0(X) of complex-valued continuous functions on ''X'' that vanish at infinity, where ''X'' is a locally compact Hausdorff space. C*-algebras were first considered primarily for their use in quantum mechanics to model algebras of physical observables. This line of research began with Werner Heisenberg's matrix mechanics and in a more mathematically developed form with Pascual Jordan around 1933. Subsequently, John von Neumann attempted to ...

Relativity Of Simultaneity
In physics, the relativity of simultaneity is the concept that ''distant simultaneity'' – whether two spatially separated events occur at the same time – is not absolute, but depends on the observer's reference frame. This possibility was raised by mathematician Henri Poincaré in 1900, and thereafter became a central idea in the special theory of relativity. Description According to the special theory of relativity introduced by Albert Einstein, it is impossible to say in an ''absolute'' sense that two distinct events occur at the same time if those events are separated in space. If one reference frame assigns precisely the same time to two events that are at different points in space, a reference frame that is moving relative to the first will generally assign different times to the two events (the only exception being when motion is exactly perpendicular to the line connecting the locations of both events). For example, a car crash in London and another in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Theory Of Relativity
The theory of relativity usually encompasses two interrelated physics theories by Albert Einstein: special relativity and general relativity, proposed and published in 1905 and 1915, respectively. Special relativity applies to all physical phenomena in the absence of gravity. General relativity explains the law of gravitation and its relation to the forces of nature. It applies to the cosmological and astrophysical realm, including astronomy. The theory transformed theoretical physics and astronomy during the 20th century, superseding a 200-year-old theory of mechanics created primarily by Isaac Newton. It introduced concepts including 4-dimensional spacetime as a unified entity of space and time, relativity of simultaneity, kinematic and gravitational time dilation, and length contraction. In the field of physics, relativity improved the science of elementary particles and their fundamental interactions, along with ushering in the nuclear age. With relativity, cosmolog ...

Nuclear Binding Energy
Nuclear binding energy in experimental physics is the minimum energy that is required to disassemble the nucleus of an atom into its constituent protons and neutrons, known collectively as nucleons. The binding energy for stable nuclei is always a positive number, as the nucleus must gain energy for the nucleons to move apart from each other. Nucleons are attracted to each other by the strong nuclear force. In theoretical nuclear physics, the nuclear binding energy is considered a negative number. In this context it represents the energy of the nucleus relative to the energy of the constituent nucleons when they are infinitely far apart. Both the experimental and theoretical views are equivalent, with slightly different emphasis on what the binding energy means. The mass of an atomic nucleus is less than the sum of the individual masses of the free constituent protons and neutrons. The difference in mass can be calculated by the Einstein equation, , where ''E'' is the nuclea ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
