Recent experiments have demonstrated that these waves can effectively simulate phase space horizons, drawing parallels to black hole physics. Specifically, the use of surface gravity water waves has enabled the observation of logarithmic phase singularities and the onset of Fermi–Dirac statistics , phenomena typically associated with quantum ...

A simple type of analogy is one that is based on shared properties; [1] [2] and analogizing is the process of representing information about a particular subject (the analogue or source system) by another particular subject (the target system), [3] in order "to illustrate some particular aspect (or clarify selected attributes) of the primary domain".
Other analogies, such as von Karman's and Prandtl's, usually result in poor relations. The most successful and most widely used analogy is the Chilton and Colburn J-factor analogy. [9] This analogy is based on experimental data for gases and liquids in both the laminar and turbulent regimes. Although it is based on experimental data, it can be ...
[3]: 210 These triumphs of physics predated the alternative more accurate model for gravity based on general relativity by many decades. Introductory physics textbooks discuss central forces , like gravity, by models based on action-at-distance without discussing the cause of such forces or issues with it until the topics of relativity and ...
Through and across analogies, also called the Trent analogy, classify the two variables making up the power conjugate pair as an across variable and a through variable. The across variable is a variable that appears across the two terminals of an element. The across variable is measured relative to the element terminals.
Douglas Richard Hofstadter (born February 15, 1945) is an American cognitive and computer scientist whose research includes concepts such as the sense of self in relation to the external world, [3] [4] consciousness, analogy-making, strange loops, artificial intelligence, and discovery in mathematics and physics.
The mechanical analogue in the impedance analogy of the constant voltage generator is the constant force generator. The mechanical analogue of the constant current generator is the constant velocity generator. [17] An example of a constant force generator is the constant-force spring. This is analogous to a real voltage source, such as a ...
