  Speaker 1: Welcome to Aaron Menkey's Cabinet of Curiosities, a production of
• 0:07
  Speaker 1: I Heart Radio and Grim and Mild. Our world is
• 0:13
  Speaker 1: full of the unexplainable, and if history is an open book,
• 0:18
  Speaker 1: all of these amazing tales are right there on display,
• 0:22
  Speaker 1: just waiting for us to explore. Welcome to the Cabinet
• 0:27
  Speaker 1: of Curiosities. Humans are curious by nature. We're driven to
• 0:39
  Speaker 1: explore our world and challenge what we know about our existence.
• 0:43
  Speaker 1: Through the centuries, we've charted lands and oceans. We've invented
• 0:47
  Speaker 1: and built a wide array of transportation methods to take
• 0:50
  Speaker 1: us too far away places, and not just horizontal travel.
• 0:55
  Speaker 1: In nineteen fifty three, two men reached the summit of
• 0:57
  Speaker 1: Mount Everest, and in recent years we sent humans in
• 1:01
  Speaker 1: submersibles through the Pacific Oceans, Mariana Trench, and then there's space.
• 1:06
  Speaker 1: We've been to the Moon and landed probes on Mars.
• 1:10
  Speaker 1: Despite the jokes, the moon is not made of cheese,
• 1:12
  Speaker 1: although the ancient Greeks did exile a philosopher for believing
• 1:16
  Speaker 1: the Moon was just a giant rock and not a god,
• 1:19
  Speaker 1: which reminds me we've believed a lot of crazy things
• 1:23
  Speaker 1: about the Earth over the years, and it's taken centuries
• 1:25
  Speaker 1: to dispel a lot of those notions. But in early
• 1:29
  Speaker 1: eighteen hundreds of America, we were still exploring and had
• 1:32
  Speaker 1: a lot of questions. Curiosity is a good thing, after all.
• 1:37
  Speaker 1: Captain John Cleaves Simes, Jr. Was a military captain who
• 1:41
  Speaker 1: had served in the War of eighteen twelve. He was
• 1:44
  Speaker 1: well educated and well read, but of all the subjects
• 1:47
  Speaker 1: he had studied, the one that interested him the most
• 1:50
  Speaker 1: was the Earth. He wasn't a scientist by any means,
• 1:54
  Speaker 1: although he had a few theories about our planet and
• 1:57
  Speaker 1: he thought we should explore them. He published a Pamplet's
• 2:00
  Speaker 1: explaining his theories in detail, and had five hundred copies made.
• 2:04
  Speaker 1: Then he toured the United States and handed them out
• 2:07
  Speaker 1: to scientists and politicians during his lectures. His theories were
• 2:11
  Speaker 1: met with plenty of skepticism, and he turned to his
• 2:14
  Speaker 1: societal connections to give him some credibility. He held a
• 2:17
  Speaker 1: fundraiser for an expedition to the North Pole. If there
• 2:20
  Speaker 1: was proper funding, he proposed explorers would bring back all
• 2:24
  Speaker 1: the proof necessary to back up his claims, and soon
• 2:27
  Speaker 1: enough he caught the attention of one politician in particular,
• 2:30
  Speaker 1: who had enough power to make his dream of exploration
• 2:33
  Speaker 1: a reality, President John Quincy Adams. During his presidency, Adams
• 2:38
  Speaker 1: established the Naval Observatory in Washington, d c. Which had
• 2:41
  Speaker 1: drawn considerable ridicule. He had also been instrumental in establishing
• 2:46
  Speaker 1: the Smithsonian Institute. John Quincy was the eldest son of
• 2:50
  Speaker 1: John Adams, the second President of the United States. Considered
• 2:53
  Speaker 1: highly intelligence, he had attended top schools all over Europe,
• 2:57
  Speaker 1: eventually earning ad mission at Harvard, where he situated at
• 3:00
  Speaker 1: the top of his class. And as a side note,
• 3:03
  Speaker 1: Adams also loved to skinny dip and regularly swam nude
• 3:07
  Speaker 1: in the Potomac River. It has no connection to our story,
• 3:11
  Speaker 1: but if that little fact has to live inside my head,
• 3:14
  Speaker 1: it gets to live inside yours as well. Like Simes,
• 3:17
  Speaker 1: Adams loved the thrill of discovery and presented the project
• 3:21
  Speaker 1: to Congress, but Congress didn't see the value in spending
• 3:24
  Speaker 1: taxpayer dollars for such an endeavor, calling it ludicrous. At
• 3:28
  Speaker 1: the time, though presidents didn't need as much approval, and
• 3:31
  Speaker 1: Adams overrode Congress and back simes proposal anyway. Simes believed
• 3:36
  Speaker 1: that the North and South Poles had deep caves and
• 3:39
  Speaker 1: he wanted to explore them. He estimated that one men
• 3:42
  Speaker 1: would be sufficient to carry out the study. At the time,
• 3:45
  Speaker 1: no one knew what minerals or metals they might find
• 3:48
  Speaker 1: along the way. But jun Quincy Adams didn't remain in
• 3:51
  Speaker 1: office long, just one term. The next President, Andrew Jackson,
• 3:55
  Speaker 1: had agreed with Congress that simes theories were ridiculous, and
• 3:59
  Speaker 1: once he was an power he immediately canceled the project.
• 4:03
  Speaker 1: By then, however, Sim's health had begun to fail and
• 4:06
  Speaker 1: he was never able to garner attention for his theories. Again,
• 4:09
  Speaker 1: well that's not exactly true. He may have inspired science
• 4:13
  Speaker 1: fiction writers years later, and what exploration had the sixth
• 4:17
  Speaker 1: President of the United States authorized a journey to the
• 4:21
  Speaker 1: center of the Earth. You see, while both Symmes and
• 4:24
  Speaker 1: Adams knew the Earth was round, they also believed that
• 4:28
  Speaker 1: it was hollow. When we think of brilliant minds, we
• 4:43
  Speaker 1: think of people like Leonardo da Vinci, Marie Curie, and
• 4:46
  Speaker 1: Alan Turing, innovators who changed art, science, and every other
• 4:50
  Speaker 1: way we understand our world. One mind, however, stands out
• 4:55
  Speaker 1: as one of the greatest in his field. Albert Einstein
• 4:58
  Speaker 1: was a man who was widely considered one of the
• 5:00
  Speaker 1: most brilliant physicists who have ever lived. Just a mention
• 5:04
  Speaker 1: of his name and one cannot help but think of
• 5:06
  Speaker 1: his theory of relativity. He equals mc squared, an equation
• 5:10
  Speaker 1: that everyone knows, but few actually understand. However, Einstein did
• 5:16
  Speaker 1: quite a bit of work before that. One of his
• 5:18
  Speaker 1: earliest papers was written on the topic of capillary action.
• 5:22
  Speaker 1: Anyone who has dipped a washcloth into a puddle of
• 5:25
  Speaker 1: water and watched the liquid creep upward has witnessed capillarity.
• 5:29
  Speaker 1: It's also called wicking, name for what happens when hot
• 5:32
  Speaker 1: wax moved toward a lit candle. Wick Einstein's article on
• 5:36
  Speaker 1: it was published in nineteen o one, and it explained
• 5:39
  Speaker 1: his theory that a force like gravity was what attracted
• 5:41
  Speaker 1: the water molecules up the sides of a tube. Unfortunately,
• 5:45
  Speaker 1: his paper wasn't accurate, but it did set the stage
• 5:48
  Speaker 1: for a breakthrough yet to come. Later. In nineteen oh five,
• 5:52
  Speaker 1: Einstein t hackled the concept that had stumped English botanist
• 5:55
  Speaker 1: Robert Brown a few decades earlier. Back in seven, Round
• 6:00
  Speaker 1: had placed to drop of dust filled water beneath his
• 6:02
  Speaker 1: microscope and noticed something odd. The bits of dust in
• 6:06
  Speaker 1: the droplet were moving all over the place, shivering randomly.
• 6:10
  Speaker 1: It wasn't until Einstein revisited Brown's observations for his own
• 6:14
  Speaker 1: paper that he found an explanation. The dust wasn't shaking
• 6:18
  Speaker 1: on its own. It was being pushed around the water
• 6:20
  Speaker 1: by molecules that were invisible to the naked eye. Though
• 6:24
  Speaker 1: the molecules would jostle the dust grains on all sides
• 6:27
  Speaker 1: equally most of the time, they could also bump them
• 6:30
  Speaker 1: from one side without warning, sending them careening elsewhere. And
• 6:34
  Speaker 1: although it was Einstein who had uncovered the truth, today
• 6:37
  Speaker 1: the concept is known as Brownie in motion. But Einstein
• 6:41
  Speaker 1: didn't sit still. He continued to research and analyze for
• 6:44
  Speaker 1: the next fifty years. For example, in nineteen seventeen, he'd
• 6:47
  Speaker 1: been theorizing about something he called spontaneous emission. It was
• 6:52
  Speaker 1: a phenomenon that occurred when an atom charged with photons
• 6:55
  Speaker 1: left its high energy state by emitting those photons, which
• 6:59
  Speaker 1: dropped into a low energy state. The process also worked
• 7:02
  Speaker 1: the other way around, too, with low energy atoms absorbing
• 7:05
  Speaker 1: photons to advance to a higher energy state. But Einstein
• 7:09
  Speaker 1: had a problem. He wanted to accurately calculate the kind
• 7:12
  Speaker 1: of radiation these atoms gave off, but other physicists were
• 7:16
  Speaker 1: finding vastly different results in their own experiments. So Einstein
• 7:19
  Speaker 1: went back to the drawing board. He looked at his
• 7:22
  Speaker 1: formulas and hypothesized that photons moved together when they were
• 7:25
  Speaker 1: in the same state. If the photons traveled in one formation,
• 7:29
  Speaker 1: then a high energy atom would emit its own photon
• 7:32
  Speaker 1: in the same direction. That had been the missing piece
• 7:35
  Speaker 1: of the puzzle, and so Einstein changed his theory from
• 7:38
  Speaker 1: spontaneous emission to stimulated emission. Thirty years later, when physicists
• 7:43
  Speaker 1: used mirrors to reflect a stream of photons, they called
• 7:46
  Speaker 1: their discovery this light amplification by stimulated emission of radiation
• 7:52
  Speaker 1: in honor of Einstein's paper, But that name was just
• 7:56
  Speaker 1: too long for normal conversation, so they simply shortened it
• 7:59
  Speaker 1: to laser, and those lasers are now used in military weapons,
• 8:04
  Speaker 1: DVD players, and even toys that we can annoy our
• 8:08
  Speaker 1: cats with. As for his work on Brownie and motion, well,
• 8:12
  Speaker 1: it's been used to analyze how stock market prices change
• 8:15
  Speaker 1: over time and to predict the performance of markets around
• 8:18
  Speaker 1: the world, and six years after publishing his article on
• 8:22
  Speaker 1: capillary action, it found its own real world application. A
• 8:26
  Speaker 1: company from Pennsylvania had been looking for an alternative to
• 8:29
  Speaker 1: cloth towels, which often became home to mold and disease
• 8:32
  Speaker 1: from frequent use. What the company eventually produced was disposable, inexpensive,
• 8:38
  Speaker 1: and absorbent. The Scott Paper Company unveiled their new paper
• 8:43
  Speaker 1: towels in nineteen o seven, and ever since, Einstein's theory
• 8:47
  Speaker 1: of capillarity is used every time someone needs to clean
• 8:51
  Speaker 1: up a big spill. Sure, Albert Einstein knew a lot
• 8:55
  Speaker 1: about the speed of light and theoretical physics, but he
• 8:58
  Speaker 1: also contributed to some of the most important scientific discoveries
• 9:02
  Speaker 1: in history. He may well have run into a few
• 9:04
  Speaker 1: bumps along the way, but he wasn't the kind of
• 9:07
  Speaker 1: guy to cry over spilt milk, because if he did,
• 9:11
  Speaker 1: he knew he had the perfect tool to mop it
• 9:15
