Skinback of the week

A correction from the New York Times:

An article on Nov. 13 about Sean Bedford, the Georgia Tech offensive lineman who is also an aerospace engineering major, misstated the terms that David Scarborough, a senior research engineer, used in teaching the jet and rocket propulsion class. The terms were “isentropic flow,” “stagnation states” and “adiabatic efficiency for the diffuser” — not “isotropic stagnation state” and “idiomatic deficiency for diffuser.”

That idiomatic deficiency will get you every time.
