Einstein's miracle year - Larry Lagerstrom
-
0:19 - 0:21As 1905 dawned,
-
0:21 - 0:27the soon-to-be 26-year-old Albert Einstein
faced life as a failed academic. -
0:27 - 0:30Most physicists of the time
would have scoffed at the idea -
0:30 - 0:35that this minor civil servant
could have much to contribute to science. -
0:35 - 0:37Yet within the following year,
-
0:37 - 0:39Einstein would publish not one,
-
0:39 - 0:40not two,
-
0:40 - 0:41not three,
-
0:41 - 0:46but four extraordinary papers,
each on a different topic, -
0:46 - 0:51that were destined to radically transform
our understanding of the universe. -
0:51 - 0:55The myth that Einstein
had failed math is just that. -
0:55 - 0:58He had mastered calculus on his own
by the age of 15 -
0:58 - 1:01and done well at both
his Munich secondary school -
1:01 - 1:03and at the Swiss Polytechnic,
-
1:03 - 1:06where he studied for
a math and physics teaching diploma. -
1:06 - 1:09But skipping classes to spend
more time in the lab -
1:09 - 1:12and neglecting to show proper deference
to his professors -
1:12 - 1:16had derailed his intended career path.
-
1:16 - 1:18Passed over even
for a lab assistant position, -
1:18 - 1:22he had to settle for a job
at the Swiss patent office, -
1:22 - 1:25obtained with the help
of a friend's father. -
1:25 - 1:27Working six days a week as a patent clerk,
-
1:27 - 1:30Einstein still managed to make
some time for physics, -
1:30 - 1:33discussing the latest work
with a few close friends, -
1:33 - 1:36and publishing a couple of minor papers.
-
1:36 - 1:37It came as a major surprise
-
1:37 - 1:43when in March 1905 he submitted
a paper with a shocking hypothesis. -
1:43 - 1:45Despite decades of evidence
that light was a wave, -
1:45 - 1:49Einstein proposed that it could,
in fact, be a particle, -
1:49 - 1:53showing that mysterious phenomena,
such as the photoelectric effect, -
1:53 - 1:56could be explained by his hypothesis.
-
1:56 - 1:58The idea was derided for years to come,
-
1:58 - 2:02but Einstein was simply
twenty years ahead of his time. -
2:02 - 2:08Wave-particle duality was slated to become
a cornerstone of the quantum revolution. -
2:08 - 2:11Two months later in May,
Einstein submitted a second paper, -
2:11 - 2:17this time tackling the centuries old
question of whether atoms actually exist. -
2:17 - 2:20Though certain theories were built on
the idea of invisible atoms, -
2:20 - 2:24some prominent scientists still
believed them to be a useful fiction, -
2:24 - 2:27rather than actual physical objects.
-
2:27 - 2:29But Einstein used an ingenious argument,
-
2:29 - 2:31showing that the behavior
of small particles -
2:31 - 2:35randomly moving around in a liquid,
known as Brownian motion, -
2:35 - 2:37could be precisely predicted
-
2:37 - 2:40by the collisions of millions
of invisible atoms. -
2:40 - 2:43Experiments soon confirmed
Einstein's model, -
2:43 - 2:47and atomic skeptics threw in the towel.
-
2:47 - 2:50The third paper came in June.
-
2:50 - 2:51For a long time,
-
2:51 - 2:53Einstein had been troubled
by an inconsistency -
2:53 - 2:56between two fundamental
principles of physics. -
2:56 - 2:59The well established
principle of relativity, -
2:59 - 3:01going all the way back to Galileo,
-
3:01 - 3:04stated that absolute motion
could not be defined. -
3:04 - 3:07Yet electromagnetic theory,
also well established, -
3:07 - 3:10asserted that absolute motion did exist.
-
3:10 - 3:13The discrepancy,
and his inability to resolve it, -
3:13 - 3:18left Einstein in what he described
as a state of psychic tension. -
3:18 - 3:19But one day in May,
-
3:19 - 3:22after he had mulled over the puzzle
with his friend Michele Besso, -
3:22 - 3:24the clouds parted.
-
3:24 - 3:27Einstein realized
that the contradiction could be resolved -
3:27 - 3:30if it was the speed of light
that remained constant, -
3:30 - 3:32regardless of reference frame,
-
3:32 - 3:36while both time and space
were relative to the observer. -
3:36 - 3:39It took Einstein only a few weeks
to work out the details -
3:39 - 3:44and formulate what came to be known
as special relativity. -
3:44 - 3:47The theory not only shattered
our previous understanding of reality -
3:47 - 3:49but would also pave the way
for technologies, -
3:49 - 3:51ranging from particle accelerators,
-
3:51 - 3:54to the global positioning system.
-
3:54 - 3:56One might think that this was enough,
-
3:56 - 3:57but in September,
-
3:57 - 4:02a fourth paper arrived as a "by the way"
follow-up to the special relativity paper. -
4:02 - 4:05Einstein had thought a little bit more
about his theory, -
4:05 - 4:09and realized it also implied
that mass and energy, -
4:09 - 4:12one apparently solid
and the other supposedly ethereal, -
4:12 - 4:15were actually equivalent.
-
4:15 - 4:19And their relationship could be expressed
in what was to become the most famous -
4:19 - 4:22and consequential equation in history:
-
4:22 - 4:25E=mc^2.
-
4:25 - 4:30Einstein would not become a world famous
icon for nearly another fifteen years. -
4:30 - 4:35It was only after his later general theory
of relativity was confirmed in 1919 -
4:35 - 4:39by measuring the bending of starlight
during a solar eclipse -
4:39 - 4:41that the press would turn him
into a celebrity. -
4:41 - 4:45But even if he had disappeared back
into the patent office -
4:45 - 4:48and accomplished nothing else after 1905,
-
4:48 - 4:50those four papers of his miracle year
-
4:50 - 4:56would have remained the gold standard
of startling unexpected genius.

As the year 1905 began, Albert Einstein faced life as a “failed” academic. Yet within the next twelve months, he would publish four extraordinary papers, each on a different topic, that were destined to radically transform our understanding of the universe. Larry Lagerstrom details these four groundbreaking papers.
