Watch Your Head 2

Randy Weiss continued a mile down the road after finding Watch Your Head and is able to find another mathematically significant road sign.

Mr. Weiss breaks from the most traditional way of achieving pi on Road Sign Math with a new approach! Apparently this strategy was suggested to him from his brother.

\sqrt{2} + \sqrt{13-10} \approx 3.1463 \approx \pi

This sign is on northbound I-95 in Connecticut. See sign on map!

    Yes - My father and older brother were the fonts of math knowledge that I drank from as a kid. Sometime (when I was probably about 8 years old) my brother told me that the sqrt(2) + sqrt(3) = Pi The way I recall it he also said, "There is no apparent reason for this." There might be a geometrical explanation, but I still don’t know it.
