Einstein's Legacy
Einstein's work didn't just advance physics — it reshaped our understanding of reality.
Scientific Impact
- GPS: Satellites must correct for relativistic effects
- Cosmology: Big Bang theory, black holes, gravitational waves
- Particle physics: E=mc² governs particle accelerators
#### Quantum Mechanics
Ironically, Einstein helped launch quantum theory (photoelectric effect), then spent decades opposing its implications.
"God does not play dice with the universe."
Yet quantum mechanics works — and EPR paradox (Einstein's critique) led to quantum entanglement research.
- Nuclear reactors
- Atomic weapons
- Medical applications (PET scans)
Einstein warned Roosevelt about bomb possibilities. He later regretted his role, becoming a peace activist.
Cultural Impact
- Wild hair, absent-minded professor stereotype
- Name synonymous with intelligence
- Most recognizable scientist in history
His thought experiments — trains, elevators, light beams — made physics accessible.
Philosophical Impact
- Is time real, or a dimension we move through?
- Is the universe deterministic?
- What does it mean that space and time are relative?
These questions still inspire physicists and philosophers.
What He Got Wrong
- Cosmological constant: Called it his "biggest blunder" (though it was later vindicated)
- Quantum mechanics: Resisted probabilistic interpretation
- Unified field theory: Spent 30 years on an unsuccessful quest
Even his failures advanced science by clarifying the problems.
Enduring Influence
- Reconciling quantum mechanics with general relativity
- Understanding dark energy (cosmological constant?)
- Exploring spacetime structure
His legacy isn't just what he discovered — it's the questions he asked.
