Road Sign Math

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.
