Code for solving the Schrödinger equation by Jonny Hyman available here: github.com/jonnyhyman/QuantumWaves

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.

Could humans ever travel to other galaxies within their lifetime? The immense scale of the Universe seems to prohibit such voyages, after all the nearest galaxy is so far away that it takes light itself — the fastest thing in the Universe — 2.5 million years to complete the trip. Remarkably, there is a trick that might allow humans to accomplish this feat — join us today as we step onboard the constantly accelerating spaceship!

Согласно теории хаоса, детерминистические системы могут быть непредсказуемы. Мы знаем все законы физики, которым они подчиняются, тем не менее, мы не можем точно рассчитать их поведение в будущем. Небольшие неточности и погрешности в расчётах накапливаются, усиливают друг друга, раз за разом приводя к вычислительной катастрофе. Будто взмах крыльев бабочки в одном полушарии стал причиной торнадо в другом. А ведь таким системам не обязательно быть очень сложными, достаточно всего трёх элементов. Так возможно ли вообще что-то предсказать?

The Earth spins on its axis, completing a full revolution every day. By why does it do this? One of the most common misconceptions in physics is the belief that constant motion requires a constant force. So many people believe there must be some force in the Earth (e.g. gravity, centrifugal force) that keeps it spinning. In truth, no force is required because a fundamental property of mass is that it maintains its state of motion in the absence of external forces. This property is called inertia.
