IGY = International Geophysical Year. It was an international scientific project that lasted from 1 July 1957 to 31 December 1958. Of course, that was long before I was born. It marked the end of a long period during the Cold War when scientific interchange between East/West had been seriously interrupted. As a fan of Donald Fagen of Steely Dan, I loved his first solo album - The Nightfly (1982). The first song on the album is I.G.Y. (What A Beautiful World). Have a listen:- So, why did I pick IGY to identify me on this forum? Because the chorus sums up my optimism about completing this challenge successfully: "What a beautiful world this will be, what a glorious time to be free."
