Talking about History......................

i was searching some technical material and came across something like "History of XXXXXXX". I was in no mood to read it and then I remembered how Mazhari sir always used to start anything with a quich review of past work..........and he used to tell it in a very interesting style..................and then old and newer technologies...................He was the only teacher who used to even mention about the year and he was so fond of those numbers...............yes, history does matter since it helps us to appreciate the progress made i.e. change vs time........we are fortunate to live in an era where technology is in very advanced stage and looking back helps us to remain optimistic about the futher developments............
