One of the most misunderstood concepts in physics is **quantum mechanics**, particularly the idea of **quantum superposition** and **wave-particle duality**.

### Quantum Superposition
In classical physics, objects are considered to exist in definite states (like being in one place at one time). However, in quantum mechanics, particles like electrons exist in a **superposition** of all possible states until measured. For instance, an electron can be in multiple locations simultaneously. Only when we observe or measure the electron does it "collapse" into one of the possible states. This is famously demonstrated by the **double-slit experiment**, where particles behave like waves until they are measured, at which point they act like particles.

### Wave-Particle Duality
This concept suggests that particles like light (photons) and electrons exhibit both **particle-like** and **wave-like** behaviors, depending on how
