Let’s start by focusing on the positive. In just 17 years, over 50 million people have been added to the rolls of Americans who can understand a newspaper story about science or technology, according to findings presented last weekend at the American Academy for the Advancement of Science’s annual meeting in San Francisco.

Michigan State University political scientist Jon D. Miller, who conducted the study, attributed some of the increase in science literacy to colleges, many of which in recent years have required that students take at least one science course. Miller says people have also added to their understanding through informal learning: reading articles and watching science reports on television.

Okay, now let’s talk (dare I say rant?) about the 200 million Americans out there who cannot read a simple story in, say, Technology Review or the New York Times science section and understand even the basics of DNA or microchips or global warming.

This level of science illiteracy may explain why over 40 percent of Americans do not believe in evolution and about 20 percent, when asked if the earth orbits the sun or vice versa, say it’s the sun that does the orbiting–placing these people in the same camp as the Inquisition that punished Galileo almost 400 years ago.
