Название: Брат (фильм)
Демобилизованный из армии Данила Багров возвращается в родной город. Скучная, однообразная жизнь провинции не может устроить крепкого русского парня, и он решает поехать в Питер, испытать себя. Тем более, что там, по слухам уже давно процветает его старший брат.
Но «новая русская» жизнь северной столицы оказывается слишком неожиданной. Даниле предстоит многое узнать… и со многими разобраться…

I learned quantum mechanics the traditional Copenhagen Interpretation way. We can use the Schrödinger equation to solve for and evolve wave functions. Then we invoke wave-particle duality, in essence things we detect as particles can behave as waves when they arent interacting with anything. But when there is a measurement, the wave function collapses leaving us with a definite particle detection. If we repeat the experiment many times, we find the statistics of these results mirror the amplitude of the wave function squared. Hence the Born rule came into being, saying the wave function should be interpreted statistically, that our universe at the most fundamental scale is probabilistic rather than deterministic. This did not sit well with scientists like Einstein and Schrödinger who believed there must be more going on, perhaps hidden variables.
In the 1950s Hugh Everett proposed the Many Worlds interpretation of quantum mechanics. It is so logical in hindsight but with a bias towards the classical world, experiments and measurements to guide their thinking, its understandable why the founders of quantum theory didnt come up with it. Rather than proposing different dynamics for measurement, Everett suggests that measurement is something that happens naturally in the course of quantum particles interacting with each other. The conclusion is inescapable. There is nothing special about measurement, it is just the observer becoming entangled with a wave function in a superposition. Since one observer can experience only their own branch, it appears as if the other possibilities have disappeared but in reality there is no reason why they could not still exist and just fail to interact with the other branches. This is caused by environmental decoherence.
