Real Science Radio hosts Bob Enyart and Fred Williams conclude their broadcasting and commenting on RSR's quantum mechanics article. There are FOUR prerequisites before listening! 1) RSR's List of Things that are Not Physical. 2) Know the 2-slit Experiment. And 3) Listen to Parts 1, 2, and 3 at rsr.org/triality, rsr.org/triality-2, and rsr.org/triality-3. If you'd like, as you listen to today's program you can follow along reading the article itself which is at rsr.org/quantum. And please consider supporting RSR by shopping, subscribing, or donating at rsr.org/store and posting a link to today's program at rsr.org/triality-4. Thanks so much!
