报告摘要：Copernicus, Galileo, Newton and others were responsible for a dramatic change in scientific thought and worldview. We continue to learn things about the cosmos that fundamentally change our understanding. The accelerating expansion of the universe is the most important cosmological discovery in many decades, and its cause is one of the most profound questions in contemporary science. This talk deals with these issues in a manner accessible to a general audience.
