The Observer Effect in Quantum Mechanics

 

I think this video is good to introduce the Bohmian mechanics.

How about inserting it into the post?

Thank you, Dosakkhayo!

Yes. It provides good visualization, and I have revised the post to add it.

• A particle ALWAYS has a definite position. But in a quantum system, position measurement can have many possible outcomes. We can only calculate the probability of finding the particle at any location.
• While either standard QM (Copenhagen interpretation) or Bohmian mechanics can be used to calculate those probabilities, Bohmian mechanics provides a realistic visualization. Copenhagen interpretation (with Schrodinger’s equation) is only a mathematical tool providing the correct answer without a “physical picture.” It is a “black box”: you input the numbers, and the answer comes out. Not interesting!
