For b = 2, 1 (the binary and unary) number systems, Benford's law is true but trivial: All binary and unary numbers (except for 0 or the empty set) start with the digit 1. (On the other hand, the generalization of Benford's law to second and later digits is not trivial, even for binary numbers.
The capacity to verify the absence of conditions such as a hidden string [ U] attached to the brick is also needed for this state of affairs [ A] to eventually falsify Newton's law of gravitation. However, these applied methodological considerations are irrelevant in falsifiability, because it is a logical criterion.
Legal liability of certified public accountants. Whether providing services as an accountant or auditor, a Certified Public Accountant (CPA) owes a duty of care to the client and third parties who foreseeably rely on the accountant's work. [1] Accountants can be sued for negligence or malpractice in the performance of their duties, and for fraud .
The exception proves the rule is a phrase that arises from ignorance, though common to good writers. The original word was preuves, which did not mean proves but tests. [ 4] In this sense, the phrase does not mean that an exception demonstrates a rule to be true or to exist, but that it tests the rule, thereby proving its value.
In finance, the rule of 72, the rule of 70[ 1] and the rule of 69.3 are methods for estimating an investment 's doubling time. The rule number (e.g., 72) is divided by the interest percentage per period (usually years) to obtain the approximate number of periods required for doubling. Although scientific calculators and spreadsheet programs ...
Gödel's second incompleteness theorem also implies that a system F 1 satisfying the technical conditions outlined above cannot prove the consistency of any system F 2 that proves the consistency of F 1. This is because such a system F 1 can prove that if F 2 proves the consistency of F 1, then F 1 is in fact consistent.
Tautology (logic) In mathematical logic, a tautology (from Ancient Greek: ταυτολογία) is a formula or assertion that is true in every possible interpretation. An example is "x=y or x≠y". Similarly, "either the ball is green, or the ball is not green" is always true, regardless of the colour of the ball. The philosopher Ludwig ...
Logical truth is one of the most fundamental concepts in logic. Broadly speaking, a logical truth is a statement which is true regardless of the truth or falsity of its constituent propositions. In other words, a logical truth is a statement which is not only true, but one which is true under all interpretations of its logical components (other ...
