33 A great physicist of this century P A M Dirac loved playing with numerical values of Fundamental constants of nature This led him to an interesting observation Dirac found that from the basic constants of atomic physics c e mass of electron mass of proton and the gravitational constant G he could arrive at a number with the dimension of time Further it was a very large number its magnitude being close to the present estimate on the age of the universe 15 billion years From the table of fundamental constants in this book try to see if you too can construct this number or any other interesting number you can think of If its coincidence with the age of the universe were significant what would this imply for the constancy of fundamental constants
