THE LIFE OF ALAIN ASPECT

                     ALAIN ASPECT

   


(French: [aspɛ]; born 15 June 1947) is a French physicist known for his experimental work on quantum entanglement. Born June 15, 1947 (age 75). He is from the Ecole Normale Supérieure of the University of Orsay.

He has received various awards in his life.

The best among them is his Nobel Prize in 2022.

Also has Hallweck Medal (1991)

Wolf Prize in Physics (2010) 

Albert Einstein Medal (2012)

He is a famous physicist.

Vision was elected a Foreign Fellow of the Royal Society (FormerMS) in 2015. Read his election certificate

For his fundamental experiments in quantum optics and nuclear physics. Alain Aspect was the first to experimentally exclude subluminal communication between measurement stations, demonstrate that quantum mechanics invalidates the separable hidden-variable theory, and experimentally demonstrate wave-particle duality of a single photon. He co-discovered the technique of velocity-selective coherent population trapping, compared the Hanbury Brown–Twiss correlation of fermions and bosons under the same conditions, and performed the first demonstration of Anderson localization in ultra-cold atomic systems. His experiments illuminate fundamental aspects of the quantum-mechanical behavior of single photons, photon pairs, and atoms. 


In 2005 he was awarded the Gold Medal of the Center National de la Recherche Scientifique, where he is Research Director. The 2010 Wolf Prize in Physics was awarded to Aspect, Anton Zeilinger, and John Clauser. In 2013 Vision was awarded both the Niels Bohr International Gold Medal and the UNESCO Niels Bohr Medal. In 2013 he was awarded the Balzan Prize for Quantum Information Processing and Communication. In 2014, he was named an Officer of the Legion of Honor. 


Vision was awarded the 2022 Nobel Prize in Physics, jointly with John Clauser and Anton Zeilinger, for "experiments with entangled photons, violations of Bell inequalities and pioneers in quantum information science". 

His educational career::

In the early 1980s, while working on his PhD (doctorate d'état) thesis, he experimented with Bell experiments that showed that Albert Einstein, Boris Podolsky, and Nathan Rosen's putative reductio ad absurdum of quantum mechanics, namely that ' implies 'physical action at a distance', realized in practice when two particles are separated by a deliberately large distance (see EPR paradox and the experiment of perspective). A correlation remains between the wavefunctions of the particles, as long as they were once part of the same continuous wavefunction before one of the child particles was measured. He earned his doctorate from Université Paris-Sud in 1983


His research topics:

Aspect tests following the first tests by Stuart Friedman and John Clauser in 1972 were considered to provide further support for the thesis that Bell's inequalities are violated in its CHSH version, specifically by closing a form of locality loophole. However, his findings were not entirely conclusive as there were gaps for alternative explanations consistent with local realism. 


After work on Bell's inequality, the approach shifted to the study of laser cooling of neutral atoms and mostly involved experiments on Bose-Einstein condensates.


Aspect was Deputy Director of the French "Grande Ecole" SuperOptique until 1994. He is a member of the French Academy of Sciences and the French Academy of Technologies and a professor at the Ecole Polytechnique.

AZIZUL KHAN, THE INVENTOR OF FINGER PRINT HISTORY

Image
   AZIZUL KHAN Khan Bahadur Qazi Azizul Haque (1872 – 1935) was a Bengali inventor and police officer in British India, notable for his work with Edward Henry and Hem Chandra Bose in developing the Henry Classification System of fingerprints, which is still in use. Haque provided the mathematical basis for the system. Haque was born in 1872 in the village of Paigram Kasba, Phultala, in the Khulna division of the Bengal Presidency (now in Bangladesh). His parents died in a boat accident when he was young. He left his family home at age 12 and went to Kolkata, where he befriended a family who became impressed with his mathematical skills and arranged for him to get a formal education. Haque studied mathematics and science at Presidency College, Kolkata. In 1892, Edward Henry of the Calcutta Police wrote to the college principal asking for the recommendation of a strong statistics student to help with his fingerprint project, and the principal nominated Haque. Henry recruited Haq...

EVOLUTION

Image
      ★★ EVOLUTION   ★★★ Evolution is change in the heritable characteristics of biological populations over successive generations.These characteristics are the expressions of genes that are passed on from parent to offspring during reproduction. Different characteristics tend to exist within any given population as a result of mutation, genetic recombination and other sources of genetic variation. Evolution occurs when evolutionary processes such as natural selection (including sexual selection) and genetic drift act on this variation, resulting in certain characteristics becoming more common or rare within a population. The evolutionary pressures that determine whether a characteristic would be common or rare within a population constantly change, resulting in a change in heritable characteristics arising over successive generations. It is this process of evolution that has given rise to biodiversity at every level of biological organisation, including the le...

THE HISTORY OF NOVEL PRICE

IN 1901, the Nobel Prize (Swedish: Nobelpriset) was introduced. Since that year, the award has been presented to various individuals and institutions around the world for successful and unique research and innovation and unparalleled humanitarian work. Awards are given in total five subjects. The subjects are: physics, chemistry, medicine, literature and peace. [1] The Nobel Prize is considered the most prestigious medal in the world in all these fields. [2] Nobel laureates are called Nobel laureates in English. The Nobel Prize was introduced in accordance with a will made by the Swedish scientist Alfred Nobel in 1895. Nobel announced the award in his will before his death. Only the Nobel Peace Prize is awarded from Oslo, Norway. In other cases, the award ceremony is held in Stockholm, Sweden. Prizes in subjects other than economics have been awarded since 1901, but economics began in 1969.  Alfred Nobel did not mention economics in his will.  The award was suspended from 194...

BIOTERRORISM (BIOWEAPON -5)

Image
  BIO TERRORISM  Biological weapons are difficult to detect, economical and easy to use, making them appealing to terrorists. The cost of a biological weapon is estimated to be about 0.05 percent the cost of a conventional weapon in order to produce similar numbers of mass casualties per kilometer square. Moreover, their production is very easy as common technology can be used to produce biological warfare agents, like that used in production of vaccines, foods, spray devices, beverages and antibiotics. A major factor in biological warfare that attracts terrorists is that they can easily escape before the government agencies or secret agencies have even started their investigation. This is because the potential organism has an incubation period of 3 to 7 days, after which the results begin to appear, thereby giving terrorists a lead. A technique called Clustered, Regularly Interspaced, Short Palindromic Repeat (CRISPR-Cas9) is now so cheap and widely available that scientists ...

HISTORY OF Submarine (PART-I)

Image
  HISTORY OF                  SUBMARINE (PART- I)  A submarine (or sub) is a watercraft capable of independent operation underwater.  It differs from a submersible, which has more limited underwater capability. The term is also sometimes used historically or colloquially to refer to remotely operated vehicles and robots, as well as medium-sized or smaller vessels, such as the midget submarine and the wet sub. Submarines are referred to as "boats" rather than "ships" irrespective of their size. Although experimental submarines had been built earlier, submarine design took off during the 19th century, and they were adopted by several navies. They were first widely used during World War I (1914–1918), and are now used in many navies, large and small. Military uses include attacking enemy surface ships (merchant and military) or other submarines, and for aircraft carrier protection, blockade running, nuclear deterrence, reconnaissa...

HISTORY OF SUBMARINE (PART-II)

Image
  SUBMARINES TECHNOLOGY   Before and during World War II, the primary role of the submarine was anti-surface ship warfare. Submarines would attack either on the surface using deck guns, or submerged using torpedoes. They were particularly effective in sinking Allied transatlantic shipping in both World Wars, and in disrupting Japanese supply routes and naval operations in the Pacific in World War II. Mine-laying submarines were developed in the early part of the 20th century. The facility was used in both World Wars. Submarines were also used for inserting and removing covert agents and military forces in special operations, for intelligence gathering, and to rescue aircrew during air attacks on islands, where the airmen would be told of safe places to crash-land so the submarines could rescue them. Submarines could carry cargo through hostile waters or act as supply vessels for other submarines. Submarines could usually locate and attack other submarines only on the surf...

Defend and BIOWEAPON -(BW8)

Image
 In 2010 at The Meeting of the States Parties to the Convention on the Prohibition of the Development, Production and Stockpiling of Bacteriological (Biological) and Toxin Weapons and Their Destruction in Geneva[] the sanitary epidemiological reconnaissance was suggested as well-tested means for enhancing the monitoring of infections and parasitic agents, for the practical implementation of the International Health Regulations (2005). The aim was to prevent and minimize the consequences of natural outbreaks of dangerous infectious diseases as well as the threat of alleged use of biological weapons against BTWC States Parties. Many countries require their active-duty military personnel to get vaccinated for certain diseases that may potentially be used as a bioweapon such as anthrax. Public health and disease surveillance It is important to note that most classical and modern biological weapons' pathogens can be obtained from a plant or an animal which is naturally infected. In the ...

BIOWEAPON (PART-3)

Image
    LAW OF               BIOWEAPON International restrictions on biological warfare began with the 1925 Geneva Protocol, which prohibits the use but not the possession or development of biological and chemical weapons. Upon ratification of the Geneva Protocol, several countries made reservations regarding its applicability and use in retaliation. Due to these reservations, it was in practice a "no-first-use" agreement only.[] The 1972 Biological Weapons Convention (BWC) supplements the Geneva Protocol by prohibiting the development, production, acquisition, transfer, stockpiling and use of biological weapons.[] Having entered into force on 26 March 1975, the BWC was the first multilateral disarmament treaty to ban the production of an entire category of weapons of mass destruction.[] As of March 2021, 183 states have become party to the treaty.[60] The BWC is considered to have established a strong global norm against biological weapons,[] wh...

BIOLOGICAL WARFARE (PART-1)

Image
    BIOLOGICAL                                WARFARE               also known as germ warfare, is the use of biological toxins or infectious agents such as bacteria, viruses, insects, and fungi with the intent to kill, harm or incapacitate humans, animals or plants as an act of war. Biological weapons (often termed "bio-weapons", "biological threat agents", or "bio-agents") are living organisms or replicating entities ( ⁠i.e. viruses, which are not universally considered "alive"). Entomological (insect) warfare is a subtype of biological warfare. ★ Offensive biological warfare is prohibited under customary international humanitarian law and several international treaties.In particular, the 1972 Biological Weapons Convention (BWC) bans the development, production, acquisition, transfer, stockpiling and use of biological weapons. Therefore, the use of bio...
