De Morgan's laws represented with Venn diagrams.In each case, the resultant set is the set of all points in any shade of blue. In propositional logic and Boolean algebra, De Morgan's laws, [1] [2] [3] also known as De Morgan's theorem, [4] are a pair of transformation rules that are both valid rules of inference.
Augustus De Morgan (27 June 1806 – 18 March 1871) was a British mathematician and logician.He is best known for De Morgan's laws, relating logical conjunction, disjunction, and negation, and for coining the term "mathematical induction", the underlying principles of which he formalized. [1]
Pythagorean theorem: It states that the area of the square whose side is the hypotenuse (the side opposite the right angle) is equal to the sum of the areas of the squares on the other two sides. The theorem can be written as an equation relating the lengths of the sides a, b and the hypotenuse c, sometimes called the Pythagorean equation: [6]

William De Morgan (1839–1917), English designer, potter, ceramics-worker, and novelist. Evelyn De Morgan (1855–1919), English pre-Raphaelite painter.
The NFL regular season is over, and NFL draft season has begun for more than half of the league's teams.. For 18 teams, the conclusion of the 2024 NFL regular season means the start of a long ...
A corresponding theorem is true for intuitionistic logic, but instead of assigning each formula a value from a Boolean algebra, one uses values from a Heyting algebra, of which Boolean algebras are a special case. A formula is valid in intuitionistic logic if and only if it receives the value of the top element for any valuation on any Heyting ...
The NFL's six wild-card games feature some potentially entertaining affairs – and maybe a few duds along the way to boot.
The agreement, which remained a secret for seven decades, is unveiled in a new book, "Jimmy: The Secret Life of James Dean." The star died in a car accident at age 24 in 1955.
