There have been lots of recent developments in astronomy and cosmology. But then, particle physicists are on the verge of discovering the Higgs boson, when the Large Hadron Collider comes back on line. But then, there have been significant advances in medicine. Embryonic stem cell trials will begin later this year in the United States, and within a few years some forms of paralysis may be cured. But then, computer scientists continue to make the same rapid advances in clock speeds and component miniaturization that has driven advances in microelectronics for the past 50 years.

What is really interesting is that scientists estimate human knowledge doubled, on average, every decade of the 20th century, but that the pace has begun to pick up, such that the amount of time it now takes for the sum total of human knowledge to double is only a few years.
