Life lesson: if you see hunters chasing buffalo off a cliff, don't stand at the bottom. Hess triangle: This used to be part of a bigger plot of land but a road destroyed it but the planners couldn't plan correctly so it left this piece of land. Horace Burgess's Treehouse: A tree house built by a minister who claimed to have received a vision ...
EDIT: You absolutely have to give a try to **SAW** and **You Are Empty**. **SAW** is a spinoff game that takes place after SAW 1's ending in an alternative universe where detective Tapp had survived.
In set theory in mathematics and formal logic, two sets are said to be disjoint sets if they have no element in common. Equivalently, two disjoint sets are sets whose intersection is the empty set. [1] For example, {1, 2, 3} and {4, 5, 6} are disjoint sets, while {1, 2, 3} and {3, 4, 5} are not disjoint. A collection of two or more sets is ...
Statement. A choice function (also called selector or selection) is a function f, defined on a collection X of nonempty sets, such that for every set A in X, f (A) is an element of A. With this concept, the axiom can be stated: Axiom — For any set X of nonempty sets, there exists a choice function f that is defined on X and maps each set of X ...

Coupon collector's problem. In probability theory, the coupon collector's problem refers to mathematical analysis of "collect all coupons and win" contests. It asks the following question: if each box of a given product (e.g., breakfast cereals) contains a coupon, and there are n different types of coupons, what is the probability that more ...
Liminal space (aesthetic) An empty hotel hallway, an example of a liminal space. In Internet aesthetics, liminal spaces are empty or abandoned places that appear eerie, forlorn, and often surreal. Liminal spaces are commonly places of transition, pertaining to the concept of liminality. Research from the Journal of Environmental Psychology has ...
We prove the finite version, using Radon's theorem as in the proof by Radon (1921).The infinite version then follows by the finite intersection property characterization of compactness: a collection of closed subsets of a compact space has a non-empty intersection if and only if every finite subcollection has a non-empty intersection (once you fix a single set, the intersection of all others ...
