[caption id="attachment_5170" align="alignright" width="480"] Professor lecturing at a blackboard[/caption] You are to undergo testing. You look at your test paper and see many examination questions... Many useful equations are arrived at by solving differential equations—for instance, the equation for the acceleration experienced by a falling object. This kind of activity involves some mathematical expertise and lots of care. When I was working in industry, my partner told me that he suspected that there was an error in arriving at the navigation equations from its differential equations. He asked me to monitor his work as he solved the equations anew. Mathematicians Do It Too I know that when a mathematician (yes, even a good one) does math, he makes mistakes. I truly believe that he tends to get the easy stuff…
