In this episode, I talk about DNA: a simple DNA diffraction and interference experiment using the spring from a pen, and the DNA, the structure of my introductory physics class during the spring '22 semester.    Full show notes at: www.physicsalive.com/dna   DNA Diffraction and Interference Lab and/or Demonstration Figure 1: X-ray diffraction pattern of B-DNA labeled Photo 51 by Rosalind Franklin. Figure 2: Interference pattern from a pen spring. Pattern produced from a red diode laser passing through the spring from a pen. Projected on a screen 8 meters away.
