The nationwide March for Science is taking place tomorrow in cities across the country, including here in Boston. Thousands are expected to gather on Boston Common in support of science, which some feel has taken a backseat when it comes to informing public policy, particularly in the early days of the Trump administration. Randy Olson is a former professor who left academia to make a career of helping other scientists translate their findings for general audiences. He's serving as an informal adviser to organizers of the March for Science, and he discussed the march's message and goals with WGBH All Things Considered host Barbara Howard.
