Andrew Rate wrote a new post, How useful are lectures, really? | Highly Allochthonous, on the site dissolution 1 year, 3 months ago

This post (quoted / linked below) struck a chord; I’ve frequently wondered about the cost-benefit balance of lectures.

…in physics at least, lectures are very bad at enabling students to conceptually grasp the material being presented. That sort of understanding requires a more interactive style of teaching…

The poem below may be the closest we’ve ever come to seeing geochemical poetry or, at least, poetry inspired by geochemistry. The inspiration is even an article in the high-impact journal Nature Geoscience!

The poet, Dan Trewear, apparently “…works as a science academic and has had a couple of poems published here and there…”. I may post…[Read more]
