For example, in the Twin paradox one twin brother goes on a trip near the speed of light and comes home younger than his twin, who stayed at home.

* Twin paradox

* Twin paradox ( special relativity )

Due to the nature of relativistic travel ( see Twin paradox ), the twin who remained behind ages faster and eventually the affinity between them is weakened to the point that they are no longer able to communicate easily.

In light speed or slower communications, this paradox is avoided due to the expected message delays, as in the Twin paradox.

* Twin Earth thought experiment

In his Twin Earth thought experiment, Hilary Putnam asks us to imagine a scenario in which there is a substance with all of the observable properties of water ( e. g., taste, color, boiling point ), but which is chemically different from water.

* Hilary Putnam's Twin Earth thought experiment in the philosophy of language and philosophy of mind

The Twin Earth thought experiment was a thought experiment presented by philosopher Hilary Putnam in his 1973 paper " Meaning and Reference " and subsequent 1975 paper " The Meaning of ' Meaning '", as an early argument for what has subsequently come to be known as semantic externalism.

Indeed, Phil Hutchinson notes that a. if one looks at Putnam's own later criticisms of others ( for example his criticisms of Jaegwon Kim in his book The Threefold Cord ) one finds that implicitly he critiques his own earlier self ; and b. that the persuasive power of the Twin Earth thought experiment / intuition pump relies on our turning a blind eye to aspects of the experiment in order that it establish that which Putnam claims it to.

On the last night of shooting Twin Peaks: Fire Walk with Me, Lynch was driving home and thought of the first third of Lost Highway all the way up to " the fist hitting Fred in the police station — to suddenly being in another place and not knowing how he got there or what is wrong.

The Lupemban is the name given by archaeologists to a central African culture which, though once thought to date between c. 30, 000 and 12, 000 BC, is now generally recognised to be far older ( dates of c. 300, 000 have been obtained from Twin Rivers, Zambia and Muguruk, Kenya, respectively ).

Under certain circumstances of confusion, this can lead to the alteration of a name's referent ( for one example of how this might happen, see Twin Earth thought experiment ).

A speaker whose environment changes may thus observe that the referents of his terms shift, as described in the Twin Earth and Swamp man thought experiments.

He is also thought to have participated in the dismantling of the Twin City Lines street railway during the early 1950s.

Twin Oaks is detailed in Kat Kinkade's book, A Walden Two experiment: The first five years of Twin Oaks Community.

The fifth and sixth paradoxes are also a single paradox and is usually thought to relate to the vagueness of language.

EPR tried to set up a paradox to question the range of true application of Quantum Mechanics: Quantum theory predicts that both values cannot be known for a particle, and yet the EPR thought experiment purports to show that they must all have determinate values.

one must not think ill of the paradox, for the paradox is the passion of thought, and the thinker without the paradox is like the lover without passion: a mediocre fellow.

This, then, is the ultimate paradox of thought: to want to discover something that thought itself cannot think.

In this study, they formulated the EPR paradox ( Einstein, Podolsky, Rosen Paradox ), a thought experiment that attempted to show that quantum mechanical theory was incomplete.

Schrödinger's cat is a thought experiment, sometimes described as a paradox, devised by Austrian physicist Erwin Schrödinger in 1935.

The thought experiment illustrates this apparent paradox.

This is often illustrated with thought experiments such as the " tachyon telephone paradox " or " logically pernicious self-inhibitor.

In physics, the twin paradox is a thought experiment in special relativity involving identical twins, one of which makes a journey into space in a high-speed rocket and returns home to find that the twin who remained on Earth has aged more.

Another approach, offered by the epistemological school of thought, suggests the unexpected hanging paradox is an example of an epistemic paradox because it turns on our concept of knowledge.

Levinthal's paradox is a thought experiment, also constituting a self-reference in the theory of protein folding.

The basic plot line is derived from a 1911 thought experiment in special relativity, commonly called the twin paradox, proposed by French physicist Paul Langevin.

Newcomb's paradox, also referred to as Newcomb's problem, is a thought experiment involving a game between two players, one of whom purports to be able to predict the future.

Although the pairings in a group of 23 people are not statistically equivalent to 253 pairs chosen independently, the birthday paradox becomes less surprising if a group is thought of in terms of the number of possible pairs, rather than as the number of individuals.

He managed to bring together the paradox of a reactionary thought which would actively change history, a form of Counter-revolution opposed to simple conservatism.

Christianity is to him the divinely absurd ( Credo quia absurdum ), not merely the relative paradox, — namely, in relation to the natural man, ensnared in sin and worldliness, which has been the doctrine of Scripture and of the Church from the beginning, — but the absolute paradox, which must be believed in defiance of all reason, because every ideal, every thought of wisdom, is excluded there from, and in every case is absolutely inaccessible to man.

The Trouton-Noble experiment is also connected to thought experiments such as the " Trouton-Noble paradox ", " Right-angle lever paradox ", or " Lewis-Tolman paradox ".

The Trouton – Noble paradox is essentially equivalent to a thought experiment called " right angle lever paradox ", first discussed by Gilbert Newton Lewis and Richard Chase Tolman in 1909.
