“If we accept that we cannot prevent science and technology from changing our world, we can at least try to ensure that the changes they make are in the right directions. In a democratic society, this means that the public needs to have a basic understanding of science, so that it can make informed decisions and not leave them in the hands of experts.” (Stephen Hawking, Black Holes and Baby Universes, p.28, Speech given in Oviedo, Spain, 1989)
Every day that has passed since this statement was made we have gained knowledge and our abilities to implement ideas have improved, both for good and ill.
According to Moore’s Law our ability to process and present information has been doubling approximately every two years. It has been almost 20 years since Stephen Hawking made the statement above. This means that approximately 10 doubling periods have passed. If we take 1989 as the baseline of when we were able to process one bit of information in a certain time, then by 2009 we will be able to process 1024 bits of information in the same time period. To do this calculation you start with 1 then multiply it by ten 2’s … 2 to the power of 10 (2^10). This growth in processing speed has allowed us to get a better understanding of the world we occupy.
