In Summer 2010 I was travelling through southern Poland and Slovakia. In the attic of some old house, I found a pile of papers filled with notes and dated 1945. They are hardly readable - the Author used almost only abbreviations in Latin, Cyrillic and Hebrew alphabets. There is a signature: "Casi.Voy" (with cyrillic). There are a few equations, and this was the only one I was able to fully decypher: 1/(4πε_0 ) e^2/r^2 =G (((2cℏG^(-1))^1/2 )/(4/3 π (√(2.5))^3 ))^2/r^2 would anyone try to interpret it?
