  2. Cantor's diagonal argument - Wikipedia

    en.wikipedia.org/wiki/Cantor's_diagonal_argument

    Cantor's diagonal argument (among various similar names [note 1]) is a mathematical proof that there are infinite sets which cannot be put into one-to-one correspondence with the infinite set of natural numbers – informally, that there are sets which in some sense contain more elements than there are positive integers.

  3. Ketupat - Wikipedia

    en.wikipedia.org/wiki/Ketupat

    Ketupat pulut is also called ketupat daun palas in Malaysia, primarily found in northern Malay Peninsula and among the Malay community of southern Thailand. Usually ketupat pouch are made from janur or young palm leaves fronds. However, in Kalimantan, nipah leaves might be used and woven into ketupat as well. [17]

  4. Isosceles trapezoid - Wikipedia

    en.wikipedia.org/wiki/Isosceles_trapezoid

    Any non-self-crossing quadrilateral with exactly one axis of symmetry must be either an isosceles trapezoid or a kite. [5] However, if crossings are allowed, the set of symmetric quadrilaterals must be expanded to include also the crossed isosceles trapezoids, crossed quadrilaterals in which the crossed sides are of equal length and the other sides are parallel, and the antiparallelograms ...

  5. Broken diagonal - Wikipedia

    en.wikipedia.org/wiki/Broken_diagonal

    One way to visualize a broken diagonal is to imagine a "ghost image" of the panmagic square adjacent to the original: The set of numbers {3, 12, 14, 5} of a broken diagonal, wrapped around the original square, can be seen starting with the first square of the ghost image and moving down to the left.

  6. Parallelogram law - Wikipedia

    en.wikipedia.org/wiki/Parallelogram_law

    Vectors involved in the parallelogram law. In a normed space, the statement of the parallelogram law is an equation relating norms: ‖ ‖ + ‖ ‖ = ‖ + ‖ + ‖ ‖,.. The parallelogram law is equivalent to the seemingly weaker statement: ‖ ‖ + ‖ ‖ ‖ + ‖ + ‖ ‖, because the reverse inequality can be obtained from it by substituting (+) for , and () for , and then simplifying.

  7. Cayley table - Wikipedia

    en.wikipedia.org/wiki/Cayley_table

    Because the group operation of an abelian group is commutative, a group is abelian if and only if its Cayley table's values are symmetric along its diagonal axis. The group {1, −1} above and the cyclic group of order 3 under ordinary multiplication are both examples of abelian groups, and inspection of the symmetry of their Cayley tables ...

  8. Tipat cantok - Wikipedia

    en.wikipedia.org/wiki/Tipat_cantok

    Tipat or ketupat is a rice cake which often serves as a replacement for rice. The peanut sauce can be either mild, or hot and spicy with the addition of chili pepper. Usually bawang goreng (fried shallots) are sprinkled upon the dish, as well as kecap manis (sweet soy sauce). It is one of the few Balinese vegetarian dishes.

  9. Diagonal lemma - Wikipedia

    en.wikipedia.org/wiki/Diagonal_lemma

    The terms "diagonal lemma" or "fixed point" do not appear in Kurt Gödel's 1931 article or in Alfred Tarski's 1936 article. Rudolf Carnap (1934) was the first to prove the general self-referential lemma , [ 6 ] which says that for any formula F in a theory T satisfying certain conditions, there exists a formula ψ such that ψ ↔ F (°#( ψ ...
