A father and son went fishing...

A father and son went fishing one day. While they were out in the boat, the boy suddenly became curious about the world around him. He asked his father, "How does this boat float?
The father replied, "Don't rightly know son." A little later, the boy looked at his father and asked, "How do fish breath underwater?"
Once again the father replied, "Don't rightly know son." A little later the boy asked his father, "Why is the sky blue?"
Again, the father replied. "Don't rightly know son." Finally, the boy asked his father, "Dad, do you mind my asking you all of these questions?"
The father replied, "Of course not, you don't ask questions, you never learn nothin'."

Fathometer

In 1928, the fathometer was patented by Herbert Grove Dorsey (No. 1,667,540). His invention was an electro-mechanical sounding instrument that measured underwater depths by using a series of electrical sounds signals and their echoes. He coined the name fathometer. The same instrument could measure both very shoal water and very deep water. His fathometers not only improved hydrographic surveying but also were valuable to the maritime shipping industry by saving time over line soundings. His instruments helped delineate much of the continental shelf and slope of the United States and its territories as well as much of the deep sea, in particular the northeast Pacific Ocean, the mid-Atlantic shelf and slope, and Gulf of Mexico.«[Image: Dorsey shown with a fathometer.]
