![]() ![]() ![]() Their contributions to mathematics, astronomy, and medicine entered and shaped Greek natural philosophy of classical antiquity, whereby formal attempts were made to provide explanations of events in the physical world based on natural causes. The earliest written records in the history of science come from Ancient Egypt and Mesopotamia in around 3000 to 1200 BCE. Science may be as old as the human species, and some of the earliest archeological evidence for scientific reasoning is tens of thousands of years old. Science is a systematic enterprise that builds and organizes knowledge in the form of testable explanations and predictions about the universe. The rest is for subscribers only.Chronology of the universe as deduced by the prevailing Big Bang theory, a result from science and obtained knowledge You have 73.43% of this article left to read. It was stronger in the quantum hypothesis than in the classical case. Depending on whether this system is quantum or not, the correlations between the series of measurement outcomes on each member of the pair would be different. This test aims to simultaneously measure the state of two particles created together. In 1964, British scientist John Bell devised a theoretical test to verify this prediction, which Albert Einstein did not believe in. The measurement of one of the member's properties immediately influences the measurement of its counterpart. It is impossible to consider the two elements of the pair as independent. It is possible that, under certain conditions, two particles remain linked by an invisible thread, even if they are separated by several kilometers. Aspect, then a thesis student at the University of Orsay, showed in 19, by means of delicate experiments now in all physics books, that it was nevertheless quite real. We are interested in your experience using the site.

It is based on at least two oddities: The fact that particles are both waves and material objects, allowing them to pass for example through two places at the same time and that the energies of these systems are not continuous but "quantized," as if it were only possible to climb a slope by jumps, stairs or a ladder. It allows geolocation by satellite thanks to high-precision clocks. It also gave birth to lasers and hard disks. Its first revolution led to the invention of transistors, electronic chips, computers and cell phones. This quantum theory, developed during the inter-war period, describes the world of matter, its particles, atoms and molecules. Aspect himself likes to call the "second quantum revolution." This revolution opens a gateway to a strange, microscopic world, as well as to unexpected and spectacular applications. The prize honors the trailblazers of what Mr. The researcher shares the famous distinction with American scientist John Clauser, 79, and Austria's Anton Zeilinger, 76, as a reward for "experiments with entangled photons, establishing the violation of Bell's inequalities and pioneering quantum information science." The Swedish Academy finally decided on Tuesday, October 4, to reward the emeritus director of research at France's National Center for Scientific Research (CNRS) and professor at the prestigious Ecole Polytechnique. The question was not whether 75-year-old Frenchman Alain Aspect would win the Nobel Prize in Physics, but when and with whom. Subscribers only Alain Aspect during the presentation of the Niels Bohr Medal by Queen Marguerite II of Denmark, in Copenhagen, in 2013. The Frenchman was honored jointly with the American John Clauser and the Austrian Anton Zeilinger for the discovery of particle entanglement, opening the way to applications in quantum information.īy David Larousserie Published on Octoat 16h34 Physics Nobel Prize awards Alain Aspect, pioneer of the 'second quantum revolution' ![]()
