One of my good friends told me that Yann Tiersen and I have birthdays on the same date! Curiously, my first ever blog posting on WordPress was about Yann’s compositions. Perusing through the list of persons born on 23 June, I recognized some other names: Alfred Kinsey (entomologist and sexologist), Alan Turing (mathematician and computer scientist), Len Hutton (English cricketer), Richard Bach (novelist) and Vint Cerf (computer scientist).
