    The most groundbreaking moment in this sense for me was when I was writing course notes for an introductory course (level 300 on my specialty, I was ready). On a small topic, I had my references lined up, until a colleague shared that the obvious, well-known, widely referenced result had been disproven a couple of years prior. The new proof is far from simple, does not belong in a level 300 class and made me scrap the whole section.

    For the interested: the course was Introduction to Numerical Analysis, the topic was the order of convergence of the bisection method. Widely known but wrong result Ironically, I can’t quickly find the paper disproving it.










  • Resist cultivation or have some other undesirable properties. Often low yield, short harvest, low yield, difficult picking or transporting.

    A favorite example of mine: oak’s acorns are sometimes edible. Roughly one in ten oaks produce edible acorns. They are indistinguishable from inedible ones unless you try them out - but inedible ones are fairly poisonous. The gene for edible acorns is recessive and it takes at least a decade before you know if a newly planted oak produces edible acorns or not, with a 10% probability of the former. It is just practically impossible to select for this criterion. Thus, we don’t eat acorns.
