I wish that works like this could be made more widely accessible. But one problem is terminology; those off-putting words that have very lucid meanings.

In biology instruction I regard as dismal, Material as wonderful as these may be presented, but when the exam comes there are questions like "Define plesiomorphy". I mean, DANG.

A goal of science ought to be sharing the wonder and joy that comes from readings such as the above. Memorizing vocabulary lists for exams just snuffs that out.

It is regrettable that so many people get introduced to science by uninspired teaching. Then decide it's not for them.. This system is as contagious as any disease we might discuss here.
