Wings of Fire: An Autobiography (Digital Exclusive Edition)

by A.P.J. Abdul Kalam

The pursuit of science is a combination of great elation and great despair. I went over many such episodes in my mind. Johannes Kepler, whose three orbital laws form the basis of space research, took nearly 17 years after formulating the two laws about planetary motion around the sun, to enunciate his third law which gives the relation between the size of the elliptical orbit and the length of time it takes for the planet to go around the sun. How many failures and frustrations must he have gone through? The idea that man could land on the moon, developed by the Russian mathematician Konstantin Tsiolkovsky, was realised after nearly four decades—and by the United States, at that. Prof. Chandrasekhar had to wait nearly 50 years before receiving the Nobel Prize for his discovery of the 'Chandrasekhar Limit', a discovery made while he was a graduate student at Cambridge in the 1930s. If his work had been recognized then, it could have led to the discovery of the Black Hole decades earlier. How many failures must von Braun have gone through before his Saturn launch vehicle put man on the moon? These thoughts helped to give me the ability to withstand apparently irreversible setbacks.
