A structure named for this scientist considers the universe as a four-dimensional affine space and requires a space of simultaneous events and a distance between those events. Taking the contraction of the Poincaré (“pwon-car-AY”) group as the speed of light tends to infinity yields a group (10[1])named for (10[1])this scientist. (10[2])A nonrelativistic tensor named for this scientist (10[1])is constructed in the light (10[1])cone of a (4,1) (“four-one”) Minkowski (-5[1])space. This man is not Hamilton, but a rotation, a translation, (10[1])and uniform motion are used to uniquely write a transformation named (10[1]-5[1])for this (-5[2])man. (10[1]-5[2])Newton’s laws are the same in all inertial (10[1])reference frames (10[1]-5[1])while Lorentz transforms are replaced by this man’s transforms (10[3])in a form of invariance named for this man. For 10 points, name this scientist (-5[1])who allegedly disproved Aristotelian gravity by dropping things off (10[1])the Leaning (10[2])Tower of (10[1])Pisa. ■END■ (10[6])
