As students study for their final exam today — I thought it appropriate to capture a Wordle moment from Dr. Evans’ Energy 1 notes. Words and equations used in this course represent powerful ideas which have driven progress in science and technology and have served as a foundation to understanding our world. When students have struggled with an exam or problem set we have encouraged them to focus on a few big ideas and general principles, to read equations as ideas and to learn to speak in this mathematical language. Study well DUML Physheads — may your admirable effort pay off with new found insight and knowledge which will change the way you view the world. Peace and blessings for the final exam!
