A blonde, seven year old boy is grinning broadly and pointing to his shirt. It is blue with a white and green design highlighting the date. September 16, 2025, or 9/16/25, which is 3 squared, 4 squared, 5 squared.

Sometimes the #sciencekid wears a #mathkid hat instead....or in this case, a shirt.

He's very concerned that not enough people know how cool today's date is.* If you're American. And have a very fluid definition of cool.

Happy #math -ing everyone!
