Many Conservatives Wage All-Out Battle Against Science

Subscriber onlyMost of my professional life has been devoted to scientific literacy: educating the general public about science. Industrialized democracies cannot survive unless the general public understands the general principles of the science that drives our economy and shapes our culture. Continue reading...

Commentary: Male instincts and the appeal of war

Subscriber onlyThe most obvious example of the "modernity paradox" -- the contradictions between science and primitive beliefs -- is modern warfare. Past wars killed and maimed combatants, while leaving most non-combatants and infrastructure intact. Beginning with aerial bombing in World War II, modern wars have been fought in the midst of civilians, and have often even been aimed directly at civilians. Continue reading...

Commentary: Climate change and the clash of cultures

Subscriber onlyThe general theme of my columns has been that a fatal contradiction runs through these modern times. On the one hand, our economy is based primarily on science and rational thought, while on the other hand our beliefs remain mired in primitive instincts and medieval superstitions. We see all around us, most obviously in places such as Syria and more subtly in American anti-intellectualism and materialism, the consequences of this clash between evidence-based conclusions and traditional beliefs.

Geological Time Scale A Worthy Project

MORE SCHOOLS SHOULD TEACH STUDENTS ABOUT EARTH’S INSPIRING 4.6 BILLION-YEAR HISTORY

Subscriber onlyUpon opening my newspaper one morning last month, I found a front-page photograph that put a big smile on my face. Science students at Springdale’s Lakeside Junior High were shown chalking 460 meters of sidewalk with figures representing 4.6 billion years of Earth’s history, with each meter symbolizing 10 million years. It’s hard to think of any project better geared than this one to fi ll a yawning gap in American education. Scientists know a lot about Earth’s long history, but we don’t teach this vital and inspiring information in many history and science courses. We need to know our roots. Continue reading...
