70-7: Question 70-7 is an exercise in quantum math. Let’s think about the various possibilities, or states, we can/should distinguish here.

1. We have electrons with spin up or down going from the source to one of the two slits. 863 more words

70-6: Probability amplitudes

This problem presents more of the same. The illustration that’s presented resembles the one below. The whole analysis is based on the assumption that we can, effectively, treat the two slits as two wave  1,775 more words
