IB Physics: The Uncertainty Principle

Explains the Heisenberg uncertainty principle both in terms of being an experimental limitation and in terms of wave packets. Applies the principle to 3 IB questions.

Many students have written to thank me for the success they had with their IB Physics exams and their IA or Extended Essay. Though the style is that of Khan Academy, the videos are more specific to the IB content, contain more simulations and interactive examples, and are performed by someone who has 25 years of experience teaching IB Physics, an MSc in Physics from a top University, and who was an NSERC scholar. "I would just like to say a massive thank you to you for uploading your videos. I started the IB [and]decided to try HL Physics as it seemed interesting. It turned out to be very far from my forté and I was consistently getting 3s and 4s in tests and mock exams. So a few months before the exam period of this year, I began to panic...Then I discovered your channel. For four weeks prior to paper one, I virtually worshipped your videos, and worked along to them in my 'Big Book of Revision.' Last week, I received my results. Incredibly and almost unbelievably, I obtained a 6 in HL Physics. Not only that, but I was 3 marks off a 7." 0:00 Consequence of Wave and Particle Nature 2:07 Estimation based on experiment 4:45 Energy time conjugate pair 6:29 IB Data Booklet 6:47 Multiple Choice 1 8:11 Multiple Choice 2 10:32 Virtual Particles 12:09 Violation of Conservation of Energy 12:54 An absolute limitation based on Wavefunctions 15:49 Multiple Choice 3
