Let’s learn about mathematical mysteries
Mathematicians are still learning new things about the nature of numbers, shapes and more
Many mysteries about the nature of numbers, shapes and other features of math remain unsolved to this day.

Most of us have only ever worked on math problems that have known solutions. Even if a puzzle stumped us, we could trust that some set of textbook facts or formulas would get us to the right answer. Or that a teacher could demonstrate the solution. But there are plenty of enduring mysteries in math that continue to confound even experts.
For instance, a mathematician recently solved a decades-old mystery about Möbius strips. The question was seemingly simple: How short could these twisty loops be? But the answer had long eluded math-curious minds.
That’s not the only longstanding math mystery to be cracked this year. After half a century of searching, mathematicians finally discovered an “einstein tile.” This weird shape can cover an infinite flat surface but only in a pattern that never repeats.
Math detectives are still seeking solutions for other problems. For example, how big of a couch can be pivoted around a corner? Or how small a blanket can cover a sleeper in any position? Such unsolved puzzles remind us that not even pro mathematicians know everything. And that, in turn, can help us conquer our own math fears.
