Advanced Topics
In a nutshell: Modern physics explores the weird and wonderful behaviors of matter and energy at the smallest and fastest scales.
## Exploring the Quantum World
Modern physics includes revolutionary ideas like quantum mechanics and relativity, which go beyond classical physics to explain new phenomena.
### Quantum Mechanics
At tiny scales, energy and matter behave in unexpected ways—particles can act like waves, and probabilities rule.
### Nuclear and Particle Physics
Discoveries about the atom’s nucleus and subatomic particles have led to technologies like nuclear power and medical imaging.
### Special Relativity
Einstein’s theory showed that space and time are linked, and nothing can go faster than light.
### Impact
Modern physics has transformed technology and our understanding of the universe.
Examples
- MRI scanners use principles of quantum mechanics to image the body.
- GPS satellites must account for relativity to provide accurate locations.
