I discovered this morning there is a cool website on the net that gives you a lot of information on interesting properties of numbers. There's a lot you can learn, like......

Omega constant is 0.567143290409783872999968662210355549753815787.........

which satisfies each of these simple equations (all equivalent):

e^x = 1/x x = ln(1/x) = - ln(x)

e^-x = x -x = ln(x)

x*e^x = 1 ln(x) = 0

x^1/x = 1/e x/ln(x) = -1

x^-1/x = (1/x)^(1/x) = e ^( ln(x)/-x) = 1

omega is a solution of ln(x) = 0 ??????

how can that be possible if ln(1)=0??

Sorry, that should read x+ln(x) = 0
