Is there anything? Or is Collins&#8217; concept of &#8220;interactive expertise&#8221; really all there is, in terms of understanding?<\/p>\n<\/blockquote>\n<p>The question isn&#8217;t unique to Daniel, of course&#8211; physicists have come up with this one all on their own, and debated it in bars and at conferences for years. I&#8217;m not aware of any conclusive answer, but it&#8217;s occasionally fun to think about. Most of the usual arguments are reproduced in one form or another in the comments to that post.<\/p>\n<p>Personally, I tend to like the possibly apocryphal comment attributed to Feynman, to the effect of &#8220;if you really understand a subject, you ought to be able to explain it in terms that a college freshman can understand.&#8221; Mere facility with numbers doesn&#8217;t equal real understanding of a subject, and if the only way you can explain some result is by invoking higher math, there&#8217;s either a problem with your model, or your understanding of it.<\/p>\n<p>At the same time, though, I&#8217;m not entirely comfortable with saying that somebody who can&#8217;t interpret the equations of physics really understands the subject.
