The Hubble Deep Field
For many centuries, astronomy has been a powerful inspirational force driving people to look further, build bigger, go deeper. Indeed, other physical sciences, mathematics and engineering have benefited greatly, and continue to benefit, from astronomical research. At the IAU general assembly I heard many speakers comment on the “Golden Age” of astronomy we currently finding ourselves in. But as one speaker argued, when was astronomy not in a Golden Age? An entire 4-day session at the GA was devoted to the topic “Accelerating the rate of astronomical discovery”, which had some fascinating talks about the way astronomical discoveries are made and how technological changes underpin progress in astronomy.
An important theme running through many talks in the session was the power of the individual in astronomy. The balance between the individual and the crowd has always been a delicate one. Many early scientists faced disbelief or even wrath from peers and society for their discoveries, from Copernicus‘ “heretic” claims of a heliocentric universe to the initial rejection of Saha‘s equation of ionisation equilibrium by the 1920′s scientific establishment. Several talks were love stories to the mavericks whose doggedness, eccentricity and creativity changed the face of astronomy, culminating in Dame Jocelyn Bell-Burnell‘s wonderful own account of her discovery of the first pulsars in the 1960s.
