Check out the physics courses that I mentioned (many of which are free!) and support this channel by going to https://brilliant.org/Sabine/ where you can create your Brilliant account. The first 200 will get 20% off the annual premium subscription. I have done quite a few videos to demystify quantum mechanics. In this video I want to explain just why quantum mechanics is weird. Is it entanglement or superpositions? Schrödinger's cats? Not quite, really. But the famous Elitzur-Vaidman Bomb Experiment demonstrates well just why quantum mechanics is weird indeed.
