π€ What Is Quantum Tunneling?
Think of a ball rolling through a hill instead of over it β impossible classically, routine in quantum physics. Particles can penetrate energy barriers they lack the energy to cross, defying everyday intuition through quantum probability.
Why does this matter? Without tunneling, the Sun wouldn't shine β protons tunnel through Coulomb barriers to fuse. Flash memory, scanning tunneling microscopes, and tunnel diodes all exploit this effect. In this simulator, adjust barrier width and particle energy to observe tunneling probability in real time.
