  2. New Math - Wikipedia

    en.wikipedia.org/wiki/New_Math

    If we would like to, we can and do say, "The answer is a whole number less than 9 and bigger than 6," but we do not have to say, "The answer is a member of the set which is the intersection of the set of those numbers which are larger than 6 and the set of numbers which are smaller than 9" ... In the "new" mathematics, then, first there must be ...

    Work on the SSMCIS program began in 1965 [3] and took place mainly at Teachers College. [9] Fehr was the director of the project from 1965 to 1973. [1] The principal consultants in the initial stages and subsequent yearly planning sessions were Marshall H. Stone of the University of Chicago, Albert W. Tucker of Princeton University, Edgar Lorch of Columbia University, and Meyer Jordan of ...

  5. Birch and Swinnerton-Dyer conjecture - Wikipedia

    en.wikipedia.org/wiki/Birch_and_Swinnerton-Dyer...

    In mathematics, the Birch and Swinnerton-Dyer conjecture (often called the Birch–Swinnerton-Dyer conjecture) describes the set of rational solutions to equations defining an elliptic curve. It is an open problem in the field of number theory and is widely recognized as one of the most challenging mathematical problems.

    The School Mathematics Study Group (SMSG) was an American academic think tank focused on the subject of reform in mathematics education.Directed by Edward G. Begle and financed by the National Science Foundation, the group was created in the wake of the Sputnik crisis in 1958 and tasked with creating and implementing mathematics curricula for primary and secondary education, [1] which it did ...

  7. 24 (puzzle) - Wikipedia

    en.wikipedia.org/wiki/24_(puzzle)

    The original version of 24 is played with an ordinary deck of playing cards with all the face cards removed. The aces are taken to have the value 1 and the basic game proceeds by having 4 cards dealt and the first player that can achieve the number 24 exactly using only allowed operations (addition, subtraction, multiplication, division, and parentheses) wins the hand.

  8. Foundations of geometry - Wikipedia

    en.wikipedia.org/wiki/Foundations_of_geometry

    In the 1960s a new set of axioms for Euclidean geometry, suitable for American high school geometry courses, was introduced by the School Mathematics Study Group (SMSG), as a part of the New math curricula. This set of axioms follows the Birkhoff model of using the real numbers to gain quick entry into the geometric fundamentals.
