** In the Star Trek: Enterprise episodes " Demons " and " Terra Prime " ( both 2005 ) it is revealed that Mars is in the process of being terraformed by use of the Verteron array which redirects comets to crashland on the planet's surface ; by 2155 the atmosphere had been sufficiently altered so that, in the lowlands, Humans could breathe the air unassisted, though temperatures were still cold enough to require thermal gear.

** In 1999, the North Atlantic Treaty Organization ( NATO ) led by the United States launched air attacks against Yugoslavia ( then composed of only Serbia and Montenegro ) to pressure the Yugoslav government to end its military operations against ethnic Albanian separatists in Kosovo due to accusations of war crimes being committed by Yugoslav military forces working alongside nationalist Serb paramilitary groups.

** Eunectes murinus, the green anaconda, the largest species, is found east of the Andes in Colombia, Venezuela, the Guianas, Ecuador, Peru, Bolivia, Brazil and on the island of Trinidad.

** Eunectes notaeus, the yellow anaconda, a smaller species, is found in eastern Bolivia, southern Brazil, Paraguay and northeastern Argentina.

** Eunectes deschauenseei, the dark-spotted anaconda, is a rare species found in northeastern Brazil and coastal French Guiana.

** Eunectes beniensis, the Bolivian anaconda, the most recently defined species, is found in the Departments of Beni and Pando in Bolivia.

** Tarski's theorem: For every infinite set A, there is a bijective map between the sets A and A × A.

** The Cartesian product of any family of nonempty sets is nonempty.

** König's theorem: Colloquially, the sum of a sequence of cardinals is strictly less than the product of a sequence of larger cardinals.

** Hausdorff maximal principle: In any partially ordered set, every totally ordered subset is contained in a maximal totally ordered subset.

** For every non-empty set S there is a binary operation defined on S that makes it a group.

** Tychonoff's theorem stating that every product of compact topological spaces is compact.

** In the product topology, the closure of a product of subsets is equal to the product of the closures.

** If S is a set of sentences of first-order logic and B is a consistent subset of S, then B is included in a set that is maximal among consistent subsets of S. The special case where S is the set of all first-order sentences in a given signature is weaker, equivalent to the Boolean prime ideal theorem ; see the section " Weaker forms " below.

** Any union of countably many countable sets is itself countable.

** If the set A is infinite, then there exists an injection from the natural numbers N to A ( see Dedekind infinite ).
