  • As 1905 dawned,

  • the soon-to-be 26-year-old Albert Einstein faced life as a failed academic.

  • Most physicists of the time would have scoffed at the idea

  • that this minor civil servant could have much to contribute to science.

  • Yet within the following year,

  • Einstein would publish not one,

  • not two,

  • not three,

  • but four extraordinary papers, each on a different topic,

  • that were destined to radically transform our understanding of the universe.

  • The myth that Einstein had failed math is just that.

  • He had mastered calculus on his own by the age of 15

  • and done well at both his Munich secondary school

  • and at the Swiss Polytechnic,

  • where he studied for a math and physics teaching diploma.

  • But skipping classes to spend more time in the lab

  • and neglecting to show proper deference to his professors

  • had derailed his intended career path.

  • Passed over even for a lab assistant position,

  • he had to settle for a job at the Swiss patent office,

  • obtained with the help of a friend's father.

  • Working six days a week as a patent clerk,

  • Einstein still managed to make some time for physics,

  • discussing the latest work with a few close friends,

  • and publishing a couple of minor papers.

  • It came as a major surprise

  • when in March 1905 he submitted a paper with a shocking hypothesis.

  • Despite decades of evidence that light was a wave,

  • Einstein proposed that it could, in fact, be a particle,

  • showing that mysterious phenomena, such as the photoelectric effect,

  • could be explained by his hypothesis.

  • The idea was derided for years to come,

  • but Einstein was simply twenty years ahead of his time.

  • Wave-particle duality was slated to become a cornerstone of the quantum revolution.

  • Two months later in May, Einstein submitted a second paper,

  • this time tackling the centuries old question of whether atoms actually exist.

  • Though certain theories were built on the idea of invisible atoms,

  • some prominent scientists still believed them to be a useful fiction,

  • rather than actual physical objects.

  • But Einstein used an ingenious argument,

  • showing that the behavior of small particles

  • randomly moving around in a liquid, known as Brownian motion,

  • could be precisely predicted

  • by the collisions of millions of invisible atoms.

  • Experiments soon confirmed Einstein's model,

  • and atomic skeptics threw in the towel.

  • The third paper came in June.

  • For a long time,

  • Einstein had been troubled by an inconsistency

  • between two fundamental principles of physics.

  • The well established principle of relativity,

  • going all the way back to Galileo,

  • stated that absolute motion could not be defined.

  • Yet electromagnetic theory, also well established,

  • asserted that absolute motion did exist.

  • The discrepancy, and his inability to resolve it,

  • left Einstein in what he described as a state of psychic tension.

  • But one day in May,

  • after he had mulled over the puzzle with his friend Michele Besso,

  • the clouds parted.

  • Einstein realized that the contradiction could be resolved

  • if it was the speed of light that remained constant,

  • regardless of reference frame,

  • while both time and space were relative to the observer.

  • It took Einstein only a few weeks to work out the details

  • and formulate what came to be known as special relativity.

  • The theory not only shattered our previous understanding of reality

  • but would also pave the way for technologies,

  • ranging from particle accelerators,

  • to the global positioning system.

  • One might think that this was enough,

  • but in Sepember,

  • a fourth paper arrived as a "by the way" follow-up to the special relativity paper.

  • Einstein had thought a little bit more about his theory,

  • and realized it also implied that mass and energy,

  • one apparently solid and the other supposedly ethereal,

  • were actually equivalent.

  • And their relationship could be expressed in what was to become the most famous

  • and consequential equation in history:

  • E=mc^2.

  • Einstein would not become a world famous icon for nearly another fifteen years.

  • It was only after his later general theory of relativity was confirmed in 1919

  • by measuring the bending of starlight during a solar eclipse

  • that the press would turn him into a celebrity.

  • But even if he had disappeared back into the patent office

  • and accomplished nothing else after 1905,

  • those four papers of his miracle year

  • would have remained the gold standard of startling unexpected genius.
