Another is a legal term, referring to the indefinite postponing of a case, "until Elijah comes". Hindi - The common phrases are (1) सूरज पश्चिम से उगा है ("sun has risen from the west") and (2) बिन मौसम की बरसात ("when it rains when it's not the season to rain"). The second one is ...
One of the widely used types of impossibility proof is proof by contradiction.In this type of proof, it is shown that if a proposition, such as a solution to a particular class of equations, is assumed to hold, then via deduction two mutually contradictory things can be shown to hold, such as a number being both even and odd or both negative and positive.
Impossibility of performance, in contract law an excuse for non-performance of a contract; Impossibility defense, a criminal defense for a crime that was legally impossible to commit; Proof of impossibility, in mathematics a proof that demonstrates that a particular problem cannot be solved
The ancient Greek term for the potential or improper infinite was apeiron (unlimited or indefinite), in contrast to the actual or proper infinite aphorismenon. [3] Apeiron stands opposed to that which has a peras (limit). These notions are today denoted by potentially infinite and actually infinite, respectively.
In epistemology, the Münchhausen trilemma is a thought experiment intended to demonstrate the theoretical impossibility of proving any truth, even in the fields of logic and mathematics, without appealing to accepted assumptions. If it is asked how any given proposition is known to be true, proof in support of that proposition may be provided ...
In mathematics there is the concept of proof of impossibility referring to problems impossible to solve. The difference between this impossibility and that of the no-go theorems is that a proof of impossibility states a category of logical proposition that may never be true; a no-go theorem instead presents a sequence of events that may never occur.
There are different ways how a regress can be vicious. The most serious type of viciousness involves a contradiction in the form of metaphysical impossibility. [4] [1] [7] Other types occur when the infinite regress is responsible for the theory in question being implausible or for its failure to solve the problem it was formulated to solve.
A contract can also be void due to the impossibility of its performance. For instance, if a contract is formed between two parties A & B but during the performance of the contract the object of the contract becomes impossible to achieve (due to action by someone or something other than the contracting parties), then the contract cannot be ...
