Famous Math Problems

Throughout history, there have been many famous math problems posed that could not be solved at the time. Some conjectures lasted for hundreds of years before being proven or disproven, and some remain unsolved. Wolfram|Alpha has knowledge of many of these famous math problems, including Hilbert's 23 problems and the Millennium Prize problems.
