I think it's great that this guy found an analytic solution to an old problem, but it is of no practical significance. Most of the complication in ballistics arises from the complicated effects of air resistance which are not limited to simple drag. Numerical solutions will still be required for anything as simple as a golf ball if you want any accuracy at all.

The NYT just posted an interesting article about it http://www.nytimes.com/2012/05/22/technology/zuckerbergs-property-status-post-marriage.html?_r=1&ref=technology.

The astute reader will note that California is a community property state (http://en.wikipedia.org/wiki/Community_property) and that Zuckerburg married the day after his company went public.

False. Zeros that lead the decimal should never be interpreted as meaningful, unless otherwise indicated.
