1905
Special Relativity
Time and space are not absolute — they are relative to the observer's velocity. The speed of light remains constant for all observers regardless of motion.
1879 – 1955 · Physicist · Nobel Laureate

His Journey
A Life that Defied Convention
Born into a world of classical physics, Einstein dismantled centuries of assumptions with thought experiments conducted in the theater of his mind — before ever touching a laboratory instrument.
1879
Born in Ulm, Germany
Albert Einstein was born on March 14th in Ulm, in the Kingdom of Württemberg in the German Empire, to Hermann and Pauline Einstein. He was noted to be a late talker as a child.
1896
Enters ETH Zurich
After failing the entrance exam on his first attempt, Einstein enrolled in the Swiss Federal Polytechnic School in Zürich, where he would study physics and mathematics.
1905
The Miracle Year — Annus Mirabilis
At just 26, Einstein published four groundbreaking papers: on the photoelectric effect, Brownian motion, special relativity, and mass–energy equivalence (E=mc²). Physics would never be the same.
1915
General Theory of Relativity
Einstein completed his masterwork — the General Theory of Relativity — describing gravity not as a force but as the curvature of spacetime caused by mass and energy.
1919
Predictions Confirmed
British astronomer Arthur Eddington confirmed Einstein's prediction that starlight bends around the Sun during a solar eclipse, making Einstein an overnight global celebrity.
1921
Nobel Prize in Physics
Einstein was awarded the Nobel Prize in Physics "for his discovery of the law of the photoelectric effect," a cornerstone of quantum theory — ironically not for relativity.
1933
Exile & Princeton
Fleeing Nazi Germany, Einstein emigrated to the United States and joined the newly formed Institute for Advanced Study in Princeton, New Jersey, where he would spend the rest of his life.
1955
A Universe Diminished
Einstein passed away on April 18th in Princeton, New Jersey, leaving behind a body of work that continues to shape cosmology, quantum physics, GPS technology, and the frontiers of human understanding.
Scientific Contributions
Theories that Shook Reality
1905
Photoelectric Effect
Light consists of discrete energy packets called photons. This discovery won him the Nobel Prize and laid the foundation for quantum mechanics and modern electronics.
1915
General Relativity
Gravity is not a force but a curvature of spacetime. Massive objects warp the fabric of the universe — predicting black holes, gravitational waves, and the Big Bang.
1905
Brownian Motion
Mathematical explanation of random particle movement that provided empirical evidence for the existence of atoms and molecules, transforming our view of matter.
1924
Bose–Einstein Condensate
Co-developed with Satyendra Nath Bose, predicting a fifth state of matter where particles at near absolute zero behave as a single quantum entity.
1917
Cosmological Model
Applied general relativity to the entire universe, producing the first relativistic cosmological model. Originally added a "cosmological constant" — later called his greatest blunder.
The Mathematics of Genius
His Most Famous Equations
Mass–Energy Equivalence · 1905
E = mc²
Perhaps the most famous equation in history. Energy equals mass multiplied by the speed of light squared — proving that mass and energy are interchangeable, unlocking nuclear physics and reshaping civilisation.
Field Equations · 1915
Gμν = 8πTμν
Einstein's field equations describe how mass and energy curve spacetime. Ten coupled, nonlinear partial differential equations — yet expressible in this elegant form — governing the geometry of the universe.
Photoelectric Effect · 1905
hν = φ + Eₖ
The energy of a photon (hν) equals the work function φ plus the kinetic energy of the emitted electron. This equation proved light is quantised and earned Einstein the Nobel Prize.
Spacetime Interval · Special Relativity
ds² = −c²dt² + dx²
The spacetime interval — invariant across all inertial reference frames. This metric unifies space and time into a single four-dimensional continuum, the backbone of special relativity.

Why He Matters Today
An Enduring Legacy
GPS Technology
GPS satellites must correct for relativistic time dilation predicted by Einstein's theories — without it, navigation would drift by 10 km per day.
Gravitational Waves
First detected by LIGO in 2015 — exactly 100 years after Einstein predicted them. Ripples in spacetime confirmed by Nobel-winning science.
Nuclear Energy
E=mc² is the theoretical foundation behind both nuclear power and atomic weapons — unlocking civilisation-scale energy from matter itself.
Black Holes
General Relativity predicted the existence of black holes. In 2019, humanity photographed one for the first time — vindicating Einstein yet again.
Solar Panels
The photoelectric effect, for which Einstein won the Nobel Prize, is the physics behind every solar cell converting sunlight to electricity.
Cosmology
The Big Bang, dark energy, the expanding universe — all emerge from Einstein's field equations, forming the bedrock of modern cosmology.
Lasers & LEDs
Einstein's concept of stimulated emission (1917) is the operating principle behind every laser, LED display, and fibre-optic communication system.
Time Itself Redefined
Einstein proved time is not absolute. It passes differently depending on gravity and velocity — a truth confirmed daily in particle accelerators worldwide.
