How useful would a minor in one of the sciences be?

You also get that from a proof-based math or rigorous science or social science class. The only departments (at my liberal arts college) where many students seem unacquainted with rigorous reasoning are the humanities. </p>

If we include include playing an instrument under “practicalities of life”, then we should also include building electrical circuits. Artistic hobbies are no more “practical” than technical ones. I was thinking of “skills for the practicalities of life” as something that helps me with other aspects of my life, including non-monetary ones, rather than something I do for the sake of itself (like playing an instrument). As L’Hopital pointed out, your use of “practical” isn’t very useful because it includes anything that anyone could ever do for fun.</p>

The average computer science major knows as little about fixing computers as the average astronomy major knows about the inner workings of modern telescopes or an English major about the production process of a dictionary.</p>
