Did you know you can build any other logic gate (such as an AND or MUX) entirely out of NAND gates alone? The required configurations are listed at https://en.wikipedia.org/wiki/NAND_logic.

Despite modern technology, chalk & talk still hasn’t gone out of style among physicists according to http://physicsworld.com/cws/article/indepth/2017/jun/01/the-power-of-the-blackboard.

As reported at https://www.sciencedaily.com/releases/2017/06/170623100433.htm, University of Illinois engineers have designed a signal that can be broadcast in a room. The signal is inaudible to human ears but creates white noise in any surreptious microphones in the room, preventing spies from listening in.

Dartmouth has an audio lecture and related documents by Oppenheimer online at http://www.dartmouth.edu/~library/digital/collections/lectures/oppenheimer/.

Spectral hole burning plus an applied voltage can be used to slow light down in a rare-earth-doped crystal, as briefly highlighted at https://physics.aps.org/synopsis-for/10.1103/PhysRevA.95.032104.
