    <dc:creator>bgporter</dc:creator><description><![CDATA[A new type of textbook

A com­pact text­book that ex­plains cal­cu­lus and me­chan­ics clearly and in­tu­itively.

Calculus and mechanics together

Cal­cu­lus and me­chan­ics are of­ten taught as sep­a­rate sub­jects. It shouldn't be like that. If you learn cal­cu­lus with­out me­chan­ics, it will be bor­ing. If you learn physics with­out cal­cu­lus, you won't truly un­der­stand.

By learn­ing both sub­jects in par­al­lel, you will be able to un­der­stand con­cepts much bet­ter. ]]></description>
