  • Shortly after, in 1869, Irish chemist Thomas Andrews studied the phase transition from a liquid to a gas and coined the term critical point to describe the condition where a gas and a liquid were indistinguishable as phases, and Dutch physicist Johannes van der Waals supplied the theoretical framework which allowed the prediction of critical behavior based on measurements at much higher temperatures.

  • Commenting on the philosophical debate sparked by the book, the physicist Sean M. Carroll asked, "Do advances in modern physics and cosmology help us address these underlying questions, of why there is something called the universe at all, and why there are things called 'the laws of physics,' and why those laws seem to take the form of quantum mechanics, and why some particular wave function and Hamiltonian? (wikipedia.org)
  • The diversity of systems and phenomena available for study makes condensed matter physics the most active field of contemporary physics: one third of all American physicists self-identify as condensed matter physicists, and the Division of Condensed Matter Physics is the largest division at the American Physical Society. (wikipedia.org)
  • The funding environment and Cold War politics of the 1960s and 1970s were also factors that lead some physicists to prefer the name "condensed matter physics", which emphasized the commonality of scientific problems encountered by physicists working on solids, liquids, plasmas, and other complex matter, over "solid state physics", which was often associated with the industrial applications of metals and semiconductors. (wikipedia.org)
  • In physics and engineering the quality factor or Q factor is a dimensionless parameter that describes how underdamped an oscillator or resonator is, and characterizes a resonator's bandwidth relative to its centre frequency. (wikipedia.org)

  • measure
  • In statistics, the Fano factor, like the coefficient of variation, is a measure of the dispersion of a probability distribution of a Fano noise. (wikipedia.org)
  • Risk Factor
  • These therapies have been improved in the past few years by the introduction of new anticoagulant drugs, such that AF - like high blood pressure or smoking - may now be considered a "modifiable" risk factor for stroke, whose treatment can reduce the degree of risk. (innovations-report.com)

  • critical
  • In 1904 he was the first to note the existence of density fluctuations in the gas phase, and in 1908 he was the first physicist to ascribe the phenomenon of critical opalescence to large density fluctuations. (wikipedia.org)
  • matter
  • According to physicist Philip Warren Anderson, the term was coined by him and Volker Heine, when they changed the name of their group at the Cavendish Laboratories, Cambridge from Solid state theory to Theory of Condensed Matter in 1967, as they felt it did not exclude their interests in the study of liquids, nuclear matter, and so on. (wikipedia.org)
  • longer
  • In 1991 he realised that the general public was no longer automatically supporting physicists and began a career explaining the positive aspects of radiation use, as well as its risks and dangers. (wikipedia.org)
