A nice look into the metatarsal-tibia-femur connection in the 100m dash

While some of the analysis in this documentary is extremely reductionistic, I applaud the high speed filming, which when played back in super slow motion, captures many of details in Asafa Powell’s stride.  Look for the metatarsal-tibia-femur connection as well as the metacarpal-ulna-humerus connection in the super slow motion sequences (5:50-6:00 and 11:50 to 12:24). Both connections work in spirals. Also of interest: the role over-efforting and “co-contractions” may have played in Asafa Powell’s loss to Tyson Gay (35:26 to 37:05).

Changing perspective with the imaginative use of constraints

Changing perspectives through an imaginative use of constraints is what leads to learning and breakthroughs–whether in the world of dance, martial arts, sports, mathematics, philosophy, cabinet making, or indeed any field you can imagine. Architect and professor, Hajime Narukawa has created the world’s most remarkable map–one which allows you to change perspective and thereby alter your concept of up, down, right, left, center, East, West, North, and South. Along with the Peters Projection, this is exactly the kind of map–or perhaps more accurately stated, these are precisely the kinds of mapping possibilities, that I have been seeking for the last 25 years.
