Most people hate the Maxwell relations in thermodynamics: there are lots, and they're bewilderingly similar, so they're hard to remember.   But what I'd like to show you now is that Hamilton's equations are a special case of the Maxwell relations!  ]]></html><thumbnail_url><![CDATA[https://i2.wp.com/math.ucr.edu/home/baez/networks/rabbit-in-hat.jpg?fit=440%2C330]]></thumbnail_url><thumbnail_height><![CDATA[250]]></thumbnail_height><thumbnail_width><![CDATA[200]]></thumbnail_width></oembed>
