Museum of Mathematics opening this Saturday in NYC!

I guess I wouldn't go on Saturday even if I lived nearby - openings are too crowded for me. I think I'd go on Monday. But alas, I live across the country, and don't know when I can get to NYC.

If you're nearby, I hope you'll go, and tell me what you think.

Here's a puzzle from the museum:

• Will the red point always be the product of the green points, for any line crossing the parabola?
• Does it work for other parabolas?

The Numberplay article sets this in a delightful Alice in Math Wonderland context.
