During an inspection visit to the Chané river, in Eastern Bolivia, in January of 1990, a colleague who taught at a Colombian university engaged me in conversation: "Ponce... What are you doing these days?" I answered that I had recently completed a paper on the Vedernikov number. Acknowledging his ignorance of the subject, he said, "The... what number?" I retorted that he should know, since I understood that he taught Open-channel Hydraulics. Noticing that he was still clueless, I added, "Don't you teach with Chow?" 1 To which he answered, "Yes, of course." I then said, "Well, it is there... in Chow." He said, "Where?" To which I responded, "In Chapter 8..." He then said, "Which one is that? And I responded, "The one titled 'Theoretical Concepts...'" Finding himself totally at a loss, he acknowledged with a grin, "Oh, yeah... that's the one we skip."
