Randy Weiss saw this mathematically significant roadsign and knew instantly that it smacked of Avogadro’s Number! He pulled off the highway and ferreted the back streets to find a view of the sign.

Mr. Weiss had to hunker down for a while to get the math to work out though. Elegant? No. But it does work.

\ln \bigl( ( \sqrt { \sqrt {146 + 6 } } ) ^{(\sqrt{22 +1})} \bigl) \times 10^{23} \rightarrow 6.02 \times 10^{23} \rightarrow N_A

This sign is on I-95 as you go through Providence, Rhose Island. See sign on map!

Ed.: In a rash of high scoring signs, this sign now takes the 2nd highest score.

Randy Weiss puts another sign on the map for Rhose Island, only a few miles from the Coventry sign. Rhose Island may be a small state, but it makes the entire country proud with it’s mathematically significant roadsigns and how approachable they are, especially for children. Bravo Ocean State!

The math here is exciting because it shows many opportunities. You can rig it together in so many ways. It’s like a lego set on a road sign. The most straithtforward solution however is below.

This sign is found at exit #8 on I-95 northbound in as you approach West Warwick, RI. The GPS coordinates are approximately N41 39 35.5 W71 31 56.8. See sign on map!

The Ocean State makes it’s first entry into road sign math with this very straightforward sign submitted by Randy Weiss. Rhose Island is an amazingly small state. When was the last time you looked at a map of it? It’s a little sliver off of the ocean. The entire state is only 1,545 square miles!

This sign, as Randy said in his submission, “is one of those grade school signs that just stands out”. The math flows nicely from bottom to top.

2 \times 3 = 6

This sign is found at exit #6 on I-95 northbound in as you approach Coventry, RI. The GPS coordinates are approximately N41 37 46.9 W71 38 08.0. See sign on map!
