Jim, I liked your comment re the Capuchin dial and not being able to get it right.
The most difficult thing with my teaching is persuading graduate students from non-western cultures to say "I don't understand that, can you explain it again please?" Seems to be a loss of face. But it sure hinders their education. You might like the attachment. Came from a US medico visiting Australia to talk re ignorance. The challenge is to know which one we are dealing with! John
