When it is remembered that knowledge exerts a self-expanding and self-regenerating power, and that the relations not only among the several American communities, but between all regions of the earth, are becoming more and more intimate, it is perhaps not presumptuous to suppose that the ripened fruits of the plan are to be developed in the intellectual, moral and social improvement of the whole human family.

1842, James Hall, James Ellsworth De Kay, William Williams Mather, Ebenezer Emmons, The Quarterly Journal of Prophecy, Volume 2, Albany, T. Weed, D. Appleton & Company and Wiley & Putnam, page 16:

But even granting that this self-regenerating energy were as vigorous as formerly, and that it has not more to do battle with now than heretofore, there is another and more serious question behind.

1850, The Quarterly Journal of Prophecy, Volume 2, J. Nisbet, pages 399–400:

The self-regenerating liver may not be exhausted even through thirty thousand years. Idea foresees that, however persistent may be any beautiful form, every form is temporary.

spaghettification

LL-Q1860 (eng)-I learned some phrases-spaghettification.wav

From spaghetti + -ification (suffix meaning ‘the process of becoming’ forming nouns), alluding to the appearance of a strand of spaghetti.

suffix

Spaghettification was due to gravity intensifying, metre by metre, in the approach to a black hole.

1977, Nigel Calder, “Starcrusher”, in The Key to the Universe: A Report on the New Physics, New York, N.Y.: Viking Press, →ISBN, page 143:

But in the approach to a black hole the effect is far stronger: the astronaut’s body is stretched out on a gravitational rack. Before he comes near the event horizon, his body will be pulled out beyond the limits that flesh and blood can stand and he will suffer the excruciating death of ‘spaghettification’ long before he is in any position to unravel the secrets of the black hole. The strength of the spaghettification effect (usually known more prosaically as ‘tidal stretch’ for it is related to the way the Moon raises tides on Earth) depends on the mass of the rack-inducing black hole.

1981, Nigel Henbest, “Black Holes”, in Mysteries of the Universe, New York, N.Y.: Van Nostrand Reinhold Company, →ISBN, page 140, column 1:

‘Spaghettification. Let me guess,’ said Rimmer. ‘I can see only two options: one – due to the bizarre effects of the intense gravitational pull, and because we’re entering a region of time and space where the laws of physics no longer apply, we all of us inexplicably develop an irresistible urge to consume vast amounts of a certain wheat-based Italian noodle conventionally served with Parmesan cheese; or two – we, the crew, get turned into spaghetti. I have a feeling we can eliminate option one.’

1990, Grant Naylor [pseudonym; Rob Grant; Doug Naylor], chapter 5, in Better Than Life, London: Viking, →ISBN, part 3 (Garbage World), page 153:

I am convinced, by arguments given by [John Archibald] Wheeler in 1957, that the end point of spaghettification—the singularity itself—is governed by a union, or marriage, of the laws of quantum mechanics and those of spacetime warpage. This must be so, since the warpage spaghettifies space on scales so extremely microscopic that they are profoundly influenced by the uncertainty principle.

2002, Kip S[tephen] Thorne, “Spacetime Warps and the Quantum World: Speculations about the Future”, in Stephen W[illiam] Hawking et al., The Future of Spacetime, New York, N.Y.: W[illiam] W[arder] Norton & Company, →ISBN, page 136:

The so-called Cauchy singularity discovered by [Roger] Penrose and his colleagues turns out to be a weak singularity, according to a classification introduced by Frank Tipler: there are no unbounded tidal forces. It is not, therefore, the kind of singularity that spells inevitable spaghettification.

2005, Michael Lockwood, “Closed Timelike Curves: Science Fact or Science Fiction?”, in The Labyrinth of Time: Introducing the Universe, Oxford, Oxfordshire: Oxford University Press, →ISBN, page 141:

During this violent spaghettification process, long, thin strands of material that make up the star collapse into the intense gravity of a black hole – which basically swallows it up like stellar spaghetti. The event releases a bright burst of energy that can be detected by astronomers.

2020 October 15, Sophie Lewis, “Star dies by ‘spaghettification’ as it’s consumed by supermassive black hole”, in CBS News, archived from the original on 2021-02-14:

2001, David Lewis, How Many Lives Has Schrödinger's Cat?, Lecture, republished in 2004, Frank Jackson, Graham Priest (editors), Lewisian Themes: The Philosophy of David K. Lewis, page 13,
There is no collapse until Wigner comes along, yet because different branches of the previous superposition have acted differently to bring about different branches of Wigner's friend, each branch of Wigner's friend is under the illusion of seeing a sharp state, and thus under an illusion of collapse.

2009, Henry Stapp, Wigner's Friend, Daniel Greenberger, Klaus Hentsche, Compendium of Quantum Physics: Concepts, Experiments, History and Philosophy, Springer, page 857,
The second step is to treat Wigner's friend as an unobserved inanimate measuring device that has two states: either it registers the photon, χ₁ or it does not χ₂.

In 1962 Eugene Wigner elaborated on the knowledge issue with his Wigner's Friend paradox, an expansion of the Schrödinger's Cat problem [11]. Wigner replaced the cat with a “friend”, i.e., an intelligent observer and at the same time replaced the hydrocyanic acid mechanism with a less lethal piece of apparatus, e.g., a light bulb that is switched on when a count is recorded.

2016, John G. Cramer, The Quantum Handshake: Entanglement, Nonlocality and Transactions, Springer, page 82:

(physics, philosophy) The hypothetical observer in a thought experiment in which Wigner, absent when his friend observes the state of a particle (in some versions, Schrödinger's cat) as it collapses from quantum superposition, concludes that both the particle and his friend remain in quantum superposition until Wigner himself learns the result of the observation.

spooky action at a distance

en-noun

spooky action at a distance (uncountable)

Calque of German spukhafte Fernwirkung. Coined by Albert Einstein as spukhafte Fernwirkungen (“spooky actions at a distance”) in a letter to Max Born on 3 March 1947 to express his scepticism about quantum mechanics, where two particles may interact instantaneously over a distance.

The correlations are thus due either to entanglement, as predicted by quantum physics, or to some hypothetical spooky action at a distance whose speed we wish to bound from below.

2008 August 14, Daniel Salart, Augustin Baas, Cyril Branciard, Nicolas Gisin, Hugo Zbinden, “Testing the speed of ‘spooky action at a distance’”, in Nature, volume 454, number 7206, →DOI, page 863:

Of course, such a correlation is in principle possible to explain without any spooky action-at-a-distance: simply assume that the “particle” really is a particle, with a definite location at all times, and about half the time the particle goes to the right and half the time it goes to the left.

2011, Tim Maudlin, Quantum Non-Locality and Relativity: Metaphysical Intimations of Modern Physics, John Wiley & Sons, →ISBN, page 240:

Once one is lead down this path, it is inevitable to conclude that spooky action at a distance occurs in nature. On the other hand, if one eschews the ontological interpretation of the wave function, then “action at a distance” is, at best, descriptive of the mathematical formalism of quantum mechanics. One must be extremely wary of extending such inferences to physical reality itself.

en-noun

/ˌnɛɡˈɛntɹɒpi/

/ˌnɛɡˈɛntɹəpi/

Erwin Schrödinger
Léon Brillouin
What is Life?

From nega- + entropy.
A blend of negative + entropy, coined by the French physicist Léon Brillouin (1889–1969). The term negative entropy was introduced by the Austrian physicist Erwin Schrödinger (1887–1961) in his book What is Life? (1944, based on lectures delivered in February 1943).

An isolated system contains negentropy if it reveals a possibility for doing mechanical or electrical work: […] A tank of compressed gas in a room at atmospheric pressure, a vacuum tank in a similar room, a charged battery, any device that can produce high grade energy (mechanical work) or be degraded by some irreversible process (thermal conduction, electrical resistivity, friction, viscosity) is a source of negentropy. […] If a living organism needs food, it is only for the negentropy it can get from it, and which is needed to make up for the losses due to mechanical work done, or simple degradation processes in the living system. Energy contained in food does not really matter, since energy is conserved and never gets lost, but negentropy is the important factor.

1956 April, Brillouin, Léon, “Summary of Thermodynamics”, in Science and Information Theory, New York, N.Y.: Academic Press, →OCLC, section 2 (The Two Principles of Thermodynamics; Entropy and Negentropy), pages 116–117:

The same magnitude, but with a minus sign, i.e., the measure of macroscopic ordering, the measure of non-uniformity in the distribution of heat, the measure of the differences in temperature—temperature gradients—is called negentropy.

1977, Boris G. Kuznetsov, Philosophy of Optimism, Moscow: Progress Publishers, page 35:

Negentropy is the difference between the entropy of a system and the entropy of the same system at equilibrium (i.e., when it has its maximum possible entropy). Since entropy measures the amount of disorder, negentropy measures order.

2013, John E. Mayfield, “The Evolution of Complexity”, in The Engine of Complexity: Evolution as Computation, New York, N.Y.: Columbia University Press, →ISBN, page 277:

(thermodynamics) The difference between the entropy of a system and the maximum possible entropy of the same system.

A measure for when the continuum hypothesis can be considered appropriate is the Knudsen¹ number, Kn, which is defined as the ratio of a characteristic molecular length scale, e.g., the mean free path of molecules, and a characteristic length scale of macroscopic flow properties, e.g. a length scale of the smallest scales of fluid motion.

2012, Clemens Chan-Braun, Turbulent Open Channel Flow, Sediment Erosion and Sediment Transport, KIT Scientific Publishing, page 7:

(physics, kinematics, continuum mechanics) The assumption, for the purposes of mathematical modelling, that the material being studied is a continuous mass rather than being composed of discrete particles.
