¶ Jitterbug
Index Entry
Jitterbug:
“You may remember my manipulation of the flexibly jointed vector equilibrium of 24 external vector members. You may remember that this device, which I call the ‘jitterbug,’ had the unique property whereby each of the diametrically opposed eight triangles moves towards its polarly opposed triangle in such a manner that the vertexes of the opposed triangles always remain in fixed positions opposite the mid-edges of their respectively opposed triangles; i.e., there are symmetrically reciprocal axes of co-rotation. You may recall that the jitterbug, when so manipulated, contracts in a comprehensively symmetrical manner as the system’s 12 vertexes approach their common system’s center at the same rates–as the system transformed from the vector equilibrium, through its icosahedral stage, to its octahedral stage, and finally, with polar torque introduced as a consequence of the momentum of the contraction, the whole system contracted into the tetrahedral phase.”
