Can the Feynman essay be about math, science, AND/or engineering?

<p>Or should it be limited to only one of the three? I don't think it makes much sense that Caltech wants us to specifically limit to one, but then again that is how they worded it...</p>

<p>I talked about both science and engineering, so it’s alright to write more than one of the three. But i guess you should have one main focus, and the rest could just be additional stuff.</p>
