## Resource

Quantum tunneling allows subatomic particles to bypass energy barriers that should be impassable according to classical physics. This episode explains how wave-particle duality enables particles to 'leak' through matter, powering everything from the sun to modern flash drives.

## Highlights
- Main idea: Quantum tunneling is possible because particles behave as probability waves (psi) rather than just solid objects
- Mechanism: An energy barrier reduces the amplitude of a particle's wave function but does not eliminate it entirely on the other side
- Variable factor: The thickness of an energy barrier directly determines the rate of particle leakage
- Scientific origin: The phenomenon was established in 1928 by scientists like Ronald Gurney and Edward Condon, building on Schrödinger's wave equation
- Practical takeaway: Without this 'glitch,' nuclear fusion in stars would be impossible and modern flash memory technology would not function
