Good grief. Lienhard's "Engines of Our Ingenuity" is a series of short (<5 min) radio monologues that are played every weekday morning and afternoon on KUHF public radio in Houston, (and other places I'm told). I would imagine that Lienhard simplified the bit to get it in the allotted time, and to make it understandable and interesting to a radio audience. I've met Lienhard several times and I can tell you that he is a quite personable guy for an old engineer. It is pretty funny to imagine Lienhard, or much else of KUHF as if it were some enclave of PC progressive liberal influence. And, if you'd ever been to the UH campus, especially the College of Engineering buildings, you probably wouldn't be stricken by the grandeur of the place.
