National Museum of Mathematics (MoMath).
Even if you flunked out of high-school geometry and prefer pie to pi, the exhibits here are cool enough to make math fun whatever your age, nine to 90, more or less.
Like math itself, the museum is full of surprises.
Explore the connection between math and music; discover how a bicycle with square wheels rides smoothly over a rough surface; ponder why a pentagon-shaped bathroom sink is more efficient than a square one; and play with algorithms that make lights change color when you move your body.
You might even discover the mathematics of language, such as iambic pentameter, the math-structured pattern of much of our favorite poetry, including rap.
Which means there is a strong math connection to the hit Broadway show Hamilton.
Opened in 2012, this museum, also known as MoMath, surprisingly is the only museum in North America dedicated to math.
Not surprisingly, one of its goals is to encourage kids to study the subject, which is why the museum can be crowded with school groups on weekdays.
The National Museum of Mathematics is at 11 East 26th Street; open daily 10 a.m.–5 p.m.; $15 adults, $9 children, students and seniors.
