Our Place in the Universe from edX

Mankind has always been driven to learn and discoverhow the Universe works. Thispursuit is made possible by our inquisitive minds and our ability to think rationally. You are cordially invited to join us on a 4-week tour to see how we have come to our current understanding of our place in the universe today.

Starting about 5000 years ago, our ancestors tracked patterns and movement of celestial objects,making religious, philosophical, and scientific interpretations of what they saw. They discovered answers to the events, shape, and structure of the Universe. Over the course of history, great scientists and astronomers including Eratosthenes, Anaximander, Aristarchus, Ptolemy, andCopernicus have contributed important theories and models that shape our understanding of the world and the Universe as we know it today.

What is important torecognize is that we did not develop this knowledge overnight. Rather, it has been a long journey of astronomical explorationthat has developed and changed as we gained new perspectives and understanding. The exciting thing is that the journey continues today and there will always be new frontiersfor us to discover and to understand.

The course provides a highly visual tour with high-density videos and special effects animations to help learners understand cosmological patterns and events. It also utilizes a first-of-its-kind e-learning app, “The Armillary Sphere.” The app offersa digital reconstruction of an ancient Armillary Sphere for MOOC learners to download and use to solve astronomical problems in real-time.
