A beginner-friendly guide to the fundamental principles of quantum mechanics. Quantum Physics: A Beginner’s Guide

While the quantum world defies our logic, it is the bedrock of reality. It suggests a universe governed by rather than certainty, where the act of looking at the world actually changes it. Quantum Physics A Beginner's Guide

Often called "spooky action at a distance" by Albert Einstein, occurs when two particles become linked in such a way that the state of one instantly influences the state of the other, regardless of the distance between them. If you measure the spin of one entangled particle, you immediately know the spin of its partner on the other side of the galaxy. 4. The Uncertainty Principle A beginner-friendly guide to the fundamental principles of

Proposed by Werner Heisenberg, the states that it is impossible to know both the exact position and the exact momentum of a particle at the same time. The more precisely you measure where a particle is, the less precisely you can know how fast it is moving. This isn't due to poor equipment, but a fundamental property of the universe. 5. Why Does It Matter? Often called "spooky action at a distance" by
