How can we understand "alive + dead" in the state of Schrödinger's cat?
We discuss the logical meaning of the "plus" sign in quantum mechanics, in particular in so-called superpositions. Doing this, we connect quantum mechanics to probability theory and we highlight the differences and commonalities of these theories.
The concepts of complementary observables and of the interference of amplitudes are explained for the example of the electron spin.
The video is mainly aimed at students who are just starting to learn quantum mechanics. The mathematical prerequisites should mostly be covered by the high school curriculum.
