1966, Bruce Jennings Muga, Experimental and Theoretical Study of Motion of a Barge as Moored in Ocean Waves, Department of Civil Engineering, University of Illinois, page 17,
It should be noted that the vertical center of gravity (VCG), the longitudinal gyradius, and the natural pitch period do not agree with those required to simulate the full-scale prototype.

The roll, pitch and yaw gyradii (k₄₄, k₅₅ and k₆₆) were determined using the pendulum method by swinging the model in the air.

1999, J. de Kat, W. Thomas III, “Extreme Broaching, Rolling and Capsizing-Model Tests and Simulations of a Steered Ship in Waves”, in Twenty-Second Symposium on Naval Hydrodynamics, National Academy Press, page 363:

Weight distribution may be considered in any desired plane, usually in longitudinal and transverse senses. It is measured by the moment of inertia and is usually expressed as the gyradius which relates the moment of inertia to displacement.[…]Thus a large gyradius, longitudinal or transverse, tends towards easy motion and is desirable in terms of comfort. In passing it might be observed that the need for a very minimum longitudinal gyradius has become an article of faith among racing sailors.

Coined by Paul Ehrenfest in 1911 in German. From the explosion of energy at the ultraviolet end of the spectrum (away from visible and infrared light) caused by the Rayleigh-Jeans Law theory. The use of UV is to represent that end of the spectrum, given that the visible spectrum represents a stand-in for the whole electromagnetic spectrum, and infrared and ultraviolet are stand-ins for the endpoints. This usage is similar to that represented by the logic behind the terms "redshift" and "blueshift", which assume endpoints of red and blue.

entransy

entransy (countable and uncountable, plural entransies)

Entransy—a physical quantity describing heat transfer ability International Journal of Heat and Mass Transfer, no. 50, pp. 2545–56, available online 26 February 2007). A descriptive concept of entransy, but without using the term ‘entransy’, was first proposed by Professor Guo's group in February 2003 as ‘heat transport potential capacity’.

blend

A new physical quantity, E#x5F;h#x3D;#x5C;frac#x7B;1#x7D;#x7B;2#x7D;Q#x5F;#x7B;vh#x7D;T [where Qᵥₕ = McᵥT is the heat stored in an object; M is the mass; cᵥ is the specific heat capacity at constant volume; T is the temperature], has been identified as a basis for optimizing heat transfer processes in terms of the analogy between heat and electrical conduction. This quantity, which will be referred to as entransy, corresponds to the electric energy stored in a capacitor.

2007, Zeng-Yuan Guo, Hong-Ye Zhu, Xin-Gang Liang, “Entransy—a physical quantity describing heat transfer ability”, in International Journal of Heat and Mass Transfer, number 50, page 2545:

The concept of ‘entransy’, a product of heat and temperature, originally called ‘heat transport potential capacity’, was introduced in 2003, as analogy to product of electrical charge and voltage, as well as other similar quantities. The concept has been extended to entransy property, as integral product of ‘stored heat’ and temperature, #x5C;frac#x7B;1#x7D;#x7B;2#x7D;Mc#x5F;vT² [where M is mass; cᵥ is specific heat capacity at constant volume; T is temperature], thus representing quantity and quality of stored heat, or thermal energy in isochoric processes without work interactions.

2017, Milivoje Kostic, “Entransy concept and controversies: A critical perspective within elusive thermal landscape”, in International Journal of Heat and Mass Transfer, number 115, page 340:

1995, William Lawrence Keith, Flow Noise Modeling, Measurement, and Control, page 45:

Each microturbulent event contributes to the wall shear stress; the low-speed streak contributes at the low end with the liftup less than the mean and the sweeps greater than the mean, so that the wall shear stress PDF can be construed as the weighted sum of the individual PDFs.

1998, Herman Branover, Yeshajahu Unger, Progress in fluid flow research: turbulence and applied MHD, →ISBN, page 418:

Near the wall, a Taylor series expansion around y = 0 gives for the liftup:

photon sphere

The radius of the photon sphere is also the lower bound for any stable orbit.

For a Schwarzschild (non-spinning) black hole, the radius of the photon sphere is 1.5 times the Schwarzschild radius.

The redshift of light leaking outward from the photon sphere is #x5C;sqrt#x7B;3#x7D;-1#x3D;0.732. All light rays approaching a black hole closer than #x5C;sqrt#x7B;3#x7D; times the radius of the photon sphere spiral inwards and are captured (see Figure 13.5).

2000, Edward Harrison, Cosmology, 2nd edition, Cambridge University Press, page 250:

For a Kerr black hole though, one that has spin, the situation is different for the orbits near the black hole. In particular, there are two photon spheres, in contrast with the one photon sphere around a stationary Schwarzschild black hole. The outermost sphere is for photons that are orbiting oppositely to the direction of rotation of the black hole (the ones we say are on retrograde orbits). Inside this is the photon sphere for photons travelling in the same sense around the black hole as it is rotating (on prograde orbits). For a very slowly rotating black hole that isn't so very different from a Schwarzschild black hole, these two photon spheres are very nearly co-spatial. For black holes of increasing spin, these surfaces are increasingly further apart.

2015, Katherine Blundell, Black Holes: A Very Short Introduction, Oxford University Press, page 44:

2017, Lori Gardi, The Mandelbrot Set as a Quasi-Black Hole, David de Hilster (editor), John Chappell Natural Philosophy Society: 2017 Proceedings, John Chappell Natural Philosophy Society, page 65,
The lesser known region just outside the black hole is referred to as the photon sphere (outer grey region in Figure 9). The photon sphere is a region of space just outside the black hole where photons are forced to travel in complex orbits due to the extreme curvature of space within this region [2]. […] Finally, the boundary that exactly separates the black hole from the photon sphere is referred to as the event horizon (white circle surrounding the black region in Figure 9).

The region inside the photon sphere has a diameter of 1.5× Schwarzschild diameter D(s), but due to the curvature, this region gets magnified to 2.6× D(s).

2022, Wouter Schmitz, Understanding Relativity, Springer, page 277:

nucleomitophobia

Coined by psychiatrist Milton Arnold Dushkin in the early 1960s, from nucleo- (“atomic nucleus”) + mito- (“mitosis”) + -phobia (“fear of”), in reference to a supposed resemblance of atomic fission to cellular division.

Nikita Krushchev's war of nerves was plainly having an effect on the U.S. citizenry... There were the usual neurotics. In Chicago, public officials received a spate of calls from women complaining that their hair curlers were radioactive, from men suspicious of the olives in their martinis. (Chicago Psychiatrist Milton A. Dushkin named the ailment "nucleomitophobia"—fear of the atom).

1961 September 29, “The People: Ready to Act”, in Time:

A physician says the Nuclear Age has spawned a new phobia—nucleomitophobia, or fear of the atom. An article in Today's Health, a magazine published by the American Medical Assn., said public officials have received a rash of calls from persons who believe they are radioactive.

1961 November 19, Cedar Rapids Gazette, page 122:

When they are frantically expanding armament and making preparations for war, and they need to create war hysteria, they encourage man-made nucleomitophobia to spread rampantly, letting people know how radioactivity is already "threatening normal life in the United States." But when they want to sell their milk, they have to try "to find ways and means to set people's minds at ease regarding the question of radioactivity." Under the capitalist system, which is characterized by irresoluble contradictions, such jokes cannot be avoided.

1963 January, Michael Freeberne, translating an article in the 1 March 1962 Hongqi (《红旗》) in "Chinese Vignettes", Problems of Communism, Vol. XII, No. 1, p. 15

Bertie Rupp, who wanted to become a farmer in his youth, is entrapped by city life and achieves brief celebrity as the man who aestheticized continuous computer stationery. Disenchantment and nucleomitophobia (an exaggerated fear of atomic Armageddon) cause him to drop out.

1988, Brian Stableford, "American Book of the Dead", Fiction & Fantasy Book Review Annual

I SUFFER, I HASTEN TO SAY, FROM NUCLEOMITOPHOBIA, THE FEAR of atomic attack, and my quest for a cure has led me to grapple with the great debate on war and peace as it is being carried on in the United States.

1999, Arthur Herzog III, The War–Peace Establishment, page vii:

Fear of nuclear weapons is known as nucleomitophobia. The same term applies to fear of atomic energy... The fear is based on a feeling by individuals that they have no control over the fate of the world and that nuclear weapons can kill off all of human life and civilization. This fear is also related to a fear of death and a fear of apocalypse, or the end of the world.

2008, Ronald M. Doctor & al., The Encyclopedia of Phobias, Fears, and Anxieties, 3rd ed., s.v. "nuclear war and nuclear weapons"

1913, Archibald Allan, Space and Personality, Edinburgh: Oliver & Boyd, page 204:

Shortly afterwards, in a book called Stupeni. Tekst khudozhnika [Steps. An Artist's Text] published in 1918 in Moscow, Kandinsky wrote about himself as the original discoverer of abstract painting and, as is the custom of discoverers, recounted what precisely became his Newton's apple.

Heisenberg cut

Named after Werner Heisenberg, who contributed to the Copenhagen interpretation of quantum mechanics, and specifically to the theory of wavefunction collapse.

The original "Copenhagen" way of describing the collapse process was tied to a mysterious thing called the "Heisenberg cut". Everything lying "below" this cut was supposed to be described in the mathematical language of quantum mechanics, whereas everything lying "above" the cut was described either in the language of classical physics, or in psychological or mental terms.[…]A principal move made by von Neumann was to show that the Heisenberg cut could be moved all the way up, so that reality was unambiguously separated into a purely mental part, and a part described in the mathematical language of quantum mechanics.

2014, Henry P. Stapp, “Quantum Physics and Philosophy of Mind”, in Antonella Corradini, Uwe Meixner, editors, Quantum Physics Meets the Philosophy of Mind, Walter de Gruyter, page 9:

Another idea is to question the impermeability of the Heisenberg cut: Is the separation between the macro and micro worlds really as sharp as Heisenberg and Bohr assumed?

2018, Lars Jaeger, The Second Quantum Revolution, Springer, page 252:

The location of the Heisenberg cut is arbitrary, but it must be at a point where classical physics assuredly holds.

2021, Carl S. Helrich, The Quantum Theory—Origins and Ideas, Springer, page 192:
