August Remote Teaching Workshop

26 Jul
AAPT-NE is hosting a virtual workshop designed for secondary physics teachers 3-5 pm on August 8th. Please register using the Google Form below:
Remote teaching strategies will include but are not limited to:
  • CK-12 free online textbook, grading syncs with Google Classroom
  • EdPuzzle – documentaries and/or upload lessons and ask questions; includes online gradebook
  • Virtual Tutoring – students point their camera at their paper while they problem solve as teacher corrects their work in real time; utilizing Breakout Rooms for students to practice problem solving in partners
  • Virtual Blackboard – techniques including Zoom annotations and writing notes (use phone and a notebook as a “Whiteboard”)
  • Phet simulations including but not limited to those posted by University of Colorado and Andrew Duffy from Boston University
  • Lab Activities that can be done at home and emphasize lab analysis with Google Sheets

Quantum mechanics is all about doing experiments. But it predicts only the possible results and the probability of obtaining each result. Results and probabilities. That’s all there are! The ultimate question is, “Is this all there is to know about the quantum experiment?” Bohr answers, “Yes. If we know the results and the probability of occurrence for each result, then we know everything there is to know about that experiment. There is nothing else!””Not so,” says Einstein. “Surely, there must be more to an experiment than just results and probabilities. Obviously, quantum mechanics does not tell us the whole story.”Bell’s theorem says they cannot both be correct. There can be no quantum mechanics that embraces the tenets of classical physics. Nature has to choose one or the other. We answer the question by taking the reader from classical physics through Bell’s theorem in the context of the Bohr-Einstein debate over the meaning of reality. The classical approach of Einstein is pitted against the quantum mechanics of Bohr, common sense against the counterintuitive nature of the new theory. Entanglement is the essential characteristic of quantum mechanics that makes it different from classical theory. And with entanglement there is no reality as we know it. In particular, we discuss the EPR experiment and Bell’s theorem in detail. At the end of it all, we are forced to conclude, as did Bell, that quantum mechanics is incompatible with classical physics. Subsequent experiments confirm that local realism, as professed in classical theory, is untenable.
