Gravity without air resistance

I am glad someone actually went out and did this:

Among other things, it shows how our intuitions are often based on the limited range of conditions experienced by our ancestors on Earth, and thus reflective of only a subset of what is true about the universe generally. We expect air resistance to exist everywhere, despite the airless character of many stellar bodies.

Of course, science fiction authors seem to expect all moons and planets to not only have atmospheres, but have atmospheres that Kirk and company can breathe unaided, but that is a different misplaced assumption.

In the spring of 2005, I graduated from the University of British Columbia with a degree in International Relations and a general focus in the area of environmental politics. In the fall of 2005, I began reading for an M.Phil in IR at Wadham College, Oxford. Outside school, I am very interested in photography, writing, and the outdoors. I am writing this blog to keep in touch with friends and family around the world, provide a more personal view of graduate student life in Oxford, and pass on some lessons I've learned here.
