About This Lesson
<p>This is the first in a series of public-domain popular science articles in which a science writer asks experts in various fields for simple answers to some of life’s harder and more fundamental questions. “Ask an Expert” Number 1- delves into particle physics by asking particle physicist Dr Jeanne Wilson three questions about radioactivity. Could be a starting point for class discussion. I would be interested to hear if this resource is useful and; if not; what could be done to make it useful.</p>
