The human mind has its limits. The universe may be infinite. How then can students begin to wrap their minds around it? Phil Sadler of the Smithsonian Astrophysical Observatory shows how to bring the cosmos down to size by using the processes of any scientific investigation: selecting a specific problem, collecting data, and building a model that both explains our observations and accurately predicts future findings.
Phil Sadler earned a B.S. in physics from the Massachusetts Institute of Technology and taught middle school science, engineering, and mathematics before earning a doctorate in education from Harvard and going on to teach Harvard’s courses for students preparing to be science educators. He is a winner of the Journal of Research in Science Teaching Award, the Astronomical Society of the Pacific’s Brennan Prize for contributions to astronomy teaching, and the American Astronomical Society Education Prize. Executive producer of the video A Private Universe, originator of the MicroObservatory network, and inventor of many devices for the teaching of astronomy, his materials and curricula are used by an estimated 15 million students every year.
