With the bustle of Massachusetts Avenue behind him, Harry C. Bradley strode briskly along the gravel path laid parallel to the bank of the Charles River basin. He then pivoted 90° to face the Grand Court of the New Technology. The interconnecting stone buildings massed to form pavilions on either side as he approached the main portico of this new temple of progress. He was a professor at the premier technology school of a nation newly confirmed on the world stage. The dome in front of him capped the colonnaded center of these commandingly geometric buildings. In the few years since the move from the old “Boston Tech” on Boylston Street, he had responded to this realization of a dream with a constructive geometry of his own: transforming the hexagram into a square and imposing that cornerstone of Greek mathematics, the Pythagorean theorem, on that most fundamental of shapes, the equilateral triangle.
