Arrowmatcher is a ballistics software for crossbow archers. It can calculate the speed, kinetic energy, trajectory, aiming solution and much more of an arrow (or bullet). It uses a simplified 6 degree of freedom model.

Controversial ideas of Williamson, Margulis & others suggest speciation by hybridizing might be more common than originally thought. Taking this concept to the nth degree & assuming that indeed, speciation mostly occurs by hybridizing events, not the accumulation of mutations or genetic drift, here is a catalogueoflife2gedcom converter. It allows the tree of life to be displayed as a human genealogy tree with hybridizing events depicted as "marriages." The idea then is that mutation accrual & genetic drift are the determining factors for "species maturation," not speciation itself. Unfortunately the Catalogue of Life Project, catalogueoflife.org, changed its database format more recently, so this converter only works on older versions of the data. ...
