    Many mathematical problems have been stated but not yet solved. These problems come from many areas of mathematics, such as theoretical physics, computer science, algebra, analysis, combinatorics, algebraic, differential, discrete and Euclidean geometries, graph theory, group theory, model theory, number theory, set theory, Ramsey theory, dynamical systems, and partial differential equations.

    Thus, on the official website of the Clay Mathematics Institute, these seven problems are officially called the Millennium Problems. To date, the only Millennium Prize problem to have been solved is the Poincaré conjecture. The Clay Institute awarded the monetary prize to Russian mathematician Grigori Perelman in 2010.

    en.wikipedia.org/wiki/Collatz_conjecture

    The smallest i such that a i < a 0 is called the stopping time of n. Similarly, the smallest k such that a k = 1 is called the total stopping time of n. [2] If one of the indexes i or k doesn't exist, we say that the stopping time or the total stopping time, respectively, is infinite. The Collatz conjecture asserts that the total stopping time ...

    Squaring the circle, the impossible problem of constructing a square with the same area as a given circle, using only a compass and straightedge. [ 7 ] Three cups problem – Turn three cups right-side up after starting with one wrong and turning two at a time.

  8. Hilbert's problems - Wikipedia

    en.wikipedia.org/wiki/Hilbert's_problems

    The 6th problem concerns the axiomatization of physics, a goal that 20th-century developments seem to render both more remote and less important than in Hilbert's time. Also, the 4th problem concerns the foundations of geometry, in a manner that is now generally judged to be too vague to enable a definitive answer.
