=== Unseen Women in Science (07:23) ===

[00:00:03]  In last week's show, we dropped a list of women scientists who made important contributions, but whose names are virtually unknown.
[00:00:11]  We all want to better understand history, and so a great place to start is to better know the full spectrum of people who contributed to making it.
[00:00:20]  But we couldn't do it all in one episode, and so today we've got another batch of these great names from the history of science.
[00:00:27]  More unsung women of science are coming up next on Skeptoid.
[00:00:36]  Hi, I'm Alex Goldman.
[00:00:38]  You may know me as the host of Reply All, but I'm done with that.
[00:00:42]  I'm doing something else now.
[00:00:44]  I've started a new podcast called Hyperfixed.
[00:00:46]  On every episode of HyperFixed, listeners write in with their problems and I try to solve them.
[00:00:51]  Some massive and life-altering, and some so minuscule it'll boggle your mind.
[00:00:55]  No matter the problem, no matter the size, I'm here for you.
[00:00:59]  That's HyperFixed, the new podcast from Radiotopia.
[00:01:02]  Find it wherever you listen to podcasts or at hyperfixedpod.com.
[00:01:12]  You're listening to Skeptoid.
[00:01:13]  I'm Brian Dunning from Skeptoid.com.
[00:01:17]  More Unsung Women of Science.
[00:01:20]  There haven't been very many times when Skeptoid episodes got a sequel the following week.
[00:01:25]  I prefer to avoid multi-part episodes as the show format is to present simple, convenient, bite-sized pieces of standalone scientific investigation.
[00:01:34]  But the volume of back-channel feedback I received from last week's list of unsung women in science made it clear that the job was left woefully underdone.
[00:01:44]  So we continue this week with the most popularly requested women whom knowledgeable researchers felt should have been included on any short list.
[00:01:54]  I would also like to address the flip side of the back channel feedback that I received, which is that this subject matter is inappropriate for Skeptoid.
[00:02:03]  Indeed, pointing out women whose scientific achievements were overlooked or miscredited to men because of their gender is arguably more of a social or moral quest than it is an evaluation of the veracity of some pseudo-scientific belief.
[00:02:19]  No argument there.
[00:02:21]  But history versus pseudo-history is also an important theme for Skeptoid, and the fact is that many chronicles of the history of science give the impression that even fewer women have impacted the sciences than opportunity allowed.
[00:02:36]  I've met a frightening proportion of people whose history education was so incomplete that they didn't know in what centuries World War I and World War II took place.
[00:02:46]  Far too many have the equally pseudo-historic view that Marie Curie was the only woman scientist.
[00:02:53]  I hereby present evidence to the contrary.
[00:02:57]  And I further claim the right as an armchair aerodynamicist to begin with a pioneer in fluid dynamics, Agnes Pockles.
[00:03:06]  Born in 1862, this German woman was hampered by the fact that women were not accepted into universities and by her family's need for her to be a full-time nurse for her ailing parents.
[00:03:18]  Nevertheless, she passionately self-educated with books and, working in her home, became probably the world's leading expert on surface tension.
[00:03:28]  She was published in top journals for over 40 years and was eventually awarded an honorary doctorate from Carolina Wilhelmina University.
[00:03:36]  Pockles is generally credited with three important advances.
[00:03:40]  A method for determining the size and shape of organic molecules called surface balancing and now known as a Langmuir trough.
[00:03:48]  the standard procedure for ensuring experimental samples are deposited upon a clean water surface, involving the use of an evaporating solvent, and her observations of the minimum area occupied by a monomolecular surface film, now called Pockle's Point.
[00:04:05]  All of this was with a high school education and having never worked professionally, and able to work with her peers only through publications.
[00:04:15]  Marietta Blau.
[00:04:17]  Born in 1894, this Austrian physicist was the first to refine the process of tracking the paths of high-energy particles in photographic emulsion to the point where the tracks of individual alpha particles and protons could be distinguished.
[00:04:33]  Hers was one of the most important advances in the field of high-energy physics experimentation.
[00:04:38]  But as a Jew, she was forced to flee Austria in 1938, completely disrupting her work.
[00:04:46]  Albert Einstein was able to hook her up to some extent, but it was six years before she was able to get to the United States and resume her work.
[00:04:54]  By then, a British physicist, C.F. Powell, had picked up her work where she'd left off.
[00:05:00]  Both were nominated for the 1950 Nobel Prize in Physics.
[00:05:04]  It went to Powell, creating one of the most infamous Nobel Prize controversies.
[00:05:10]  It should be noted that all the years of her most important work was as an unpaid scientist, as was the rule for women at the Austrian Institute where she worked.
[00:05:19]  She was supported by her family.
[00:05:21]  In 1962, the Austrian Academy of Sciences awarded her its Erwin Schrödinger Prize.
[00:05:29]  Inge Lehmann.
[00:05:31]  Born in 1888, this Danish geophysicist first challenged the standard model of the Earth's interior as a single homogeneous liquid core.
[00:05:41]  Her study of seismic waves led her to the discovery of the Earth's solid inner core, which reflected seismic waves differently.
[00:05:49]  Also named for her is the Lehmann discontinuity, a subcontinental layer some 220 kilometers below the Earth's surface, at which seismic waves accelerate and change direction.
[00:06:02]  Lehmann won all sorts of accolades and awards and honorary degrees throughout her distinguished career.
[00:06:08]  But how many of us have heard her name, even though we all studied the Earth's core in grade school?
[00:06:13]  Today, the American Geophysical Union gives out the Inge Lehmann Medal to recognize outstanding contributions to our understanding of the Earth's core.
[00:06:23]  Berta Karlik, born in 1904.
[00:06:27]  This Austrian physicist was a friend and correspondent of Marie Curie and several of her female researchers.
[00:06:34]  By the time she worked with a team that did important work characterizing the radioactive elements present in seawater, her resume was already looking pretty impressive as a leader in radioactivity.
[00:06:45]  At the time, researchers everywhere were racing to find astatine, element number 85 in the periodic table, which nobody seemed to be able to find in nature.
[00:06:55]  Some guys were finally able to synthesize it, but it wasn't until her discovery during World War II of three naturally occurring isotopes, proving that it is produced naturally as a byproduct of the radioactive decay of heavier elements.
[00:07:10]  She won several awards for this and was made director of the Institute for Radium Research in Vienna where she worked, and became the first female full professor at the University of Vienna in 1956.

=== The First Female Author (07:06) ===

[00:07:27]  Hey everyone, I want to remind you about a truly unique and once-in-a-lifetime adventure.
[00:07:33]  Join me and Mediterranean archaeologist Dr. Flint Dibble for a skeptoid sailing adventure through the Mediterranean Sea aboard the SV Royal Clipper, the world's largest full-rigged sailing ship.
[00:07:46]  This is also the only opportunity you'll have to hear Flint and I talk about our experiences when we both went on Joe Rogan to represent the causes of science and reality against whatever it is that you get when you're thrown into that lion pit.
[00:08:01]  We set sail from Malagas, Spain on April 18th, 2026 and finished the adventure in Nice, France on April 25th.
[00:08:09]  You'll enjoy a fascinating skeptical mini-conference at sea.
[00:08:14]  You'll visit amazing ports along the Spanish and French coasts and Flint will be our exclusive onboard expert sharing the real archaeology and history about every stop.
[00:08:25]  We've got special side quests and extra skeptical content planned at each port.
[00:08:30]  This is a true sailing ship.
[00:08:32]  You can climb the rat lines to the crow's nest, handle the sails.
[00:08:36]  You can even take the helm and steer.
[00:08:38]  This is a real bucket list adventure you don't want to miss.
[00:08:42]  But cabins are selling fast and this ship does always sell out.
[00:08:46]  Act now or you'll miss this once-in-a-lifetime opportunity.
[00:08:50]  Get the full details and book your cabin at skeptoid.com slash adventures.
[00:08:56]  Hope to see you on board.

[00:09:07]  Virginia Apgar.
[00:09:09]  Born in 1909, she's the doctor whose name you didn't know you knew.
[00:09:15]  There weren't many women doctors in the 1930s, but she was one of them and also a surgeon and also created the Department of Anesthesiology at Columbia University.
[00:09:25]  But it was when she did a statistical study of newborn mortality that her name became a household word.
[00:09:31]  When a baby is born and assessed, it's given an Apgar score, which is an acronym for the five things it measures, appearance, pulse, grimace, activity, and respiration.
[00:09:42]  But the acronym is just fortuosity.
[00:09:45]  Its real root is the name of Dr. Apgar herself.
[00:09:49]  In 1994, the United States Postal Service issued a 20-cent Great Americans series postage stamp featuring Dr. Apgar.
[00:09:58]  Marie Tharp.
[00:10:00]  Born in 1920, this geologist spent years drawing maps of the ocean floor from data collected by her research partner Bruce Heason because women were not allowed aboard the research ships.
[00:10:12]  But this forced sequestration had a perk.
[00:10:15]  She became the first person to show that the mid-oceanic ridge extended all the way around the world, and by comparing these maps to earthquake maps, proved that the continental plates are indeed moving around.
[00:10:28]  Until then, plate tectonics had been considered an old-fashioned and discredited notion, proposed by the German geophysicist Alfred Wegener.
[00:10:37]  Although nearly all of Tharp's work was done in close partnership with Heason, he stubbornly refused to accept the continental drift explanation for the ridge for some time, thus leaving the credit to Tharp.
[00:10:49]  Today, Google Earth users can view our oceans with the Marie Tharp Historical Map Layer.
[00:10:56]  Maria Sebilla Marion Born in 1647 in Prussia, Marion showed us what was reasonably possible in a century where any sort of a formal education was virtually unobtainable for a woman, to say nothing of paid scientific employment.
[00:11:12]  She was nuts for bugs.
[00:11:15]  How does one make a career out of that?
[00:11:17]  She documented bugs.
[00:11:18]  She drew them, she logged their behavior, and published them in books, her first when she was only 28.
[00:11:25]  Her focus was on metamorphoses, such as caterpillars to butterflies, during a time when this process was poorly understood and often misrepresented.
[00:11:34]  When she was living in Amsterdam, she was given a private commission to the Dutch colony of Suriname and spent a few years there collecting insects, although not as long as she would have liked because she quickly contracted an illness, possibly malaria, and had to return to Europe.
[00:11:49]  But it was enough to prompt her major book, The Metamorphosis of the Insects of Suriname, and to this day she's considered one of the greatest early entomologists.
[00:11:59]  She was featured on Germany's 500 Deutschemark note.
[00:12:04]  Maria Gaetana Agnesi.
[00:12:06]  Born in 1718, this Italian mathematician, whose name I've just butchered, displays one stark departure from her comrades on this list.
[00:12:16]  She never wanted to work in the sciences.
[00:12:19]  Her father made her.
[00:12:21]  And when he died when she was 34 years old, she quit outright and devoted the rest of her life to the church and the service of the poor.
[00:12:28]  But that short career had quite the impact.
[00:12:31]  She's best known as the first female author of a mathematical text.
[00:12:36]  It was a 1,020-page textbook for Italian schoolchildren called Instituzione Analytica ad Uso de Aggiovente Italiana.
[00:12:48]  To say it was well received would be an understatement.
[00:12:51]  Pope Benedict XIV appointed her to the University of Bologna, which she declined, and Empress Maria Theresa of Austria, a great booster of the sciences and a skeptic, and familiar to skeptoid listeners from her episode on the chess-playing mechanical turk, and to whom Agnesi dedicated her book, awarded her diamonds and other precious jewels.
[00:13:13]  A famous curve used in calculus called the Witch of Agnesi is named for her, though it had nothing to do with anyone thinking she was a witch.
[00:13:21]  It was a mistranslation of the verb to turn.
[00:13:24]  She also has a crater on Venus named after her.
[00:13:28]  Alice Hamilton.
[00:13:30]  Born in 1869, she lived until 1970, 101 years of great science.
[00:13:37]  She was an American bacteriologist and toxicologist steered by fate into industrial health, protecting workers from toxic substances of all kinds.
[00:13:48]  She was the head of Illinois' Occupational Diseases Commission, the original forerunner of today's Occupational Safety and Health Administration.
[00:13:56]  When Harvard University started a program in industrial medicine in 1919, Hamilton was the nation's leading expert.
[00:14:04]  In fact, she was practically the only expert.
[00:14:07]  So she became Harvard Medical School's first female faculty member ever.
[00:14:12]  But just so she wouldn't get the idea that she was being given special treatment, she was forbidden to attend commencement ceremonies, could not go into the Harvard Club, and was not allowed to have faculty tickets to football games.
[00:14:24]  In 1995, the United States Postal Service issued a commemorative stamp featuring Dr. Hamilton, and you've probably never heard her name.

=== Skepticism as Medicine (02:34) ===

[00:14:34]  For most of these great scientists, I've tried to mention their most significant recognitions, such as being featured on a stamp or currency or having a prize named after them.
[00:14:43]  But I also titled this episode, Unsung Women of Science.
[00:14:47]  Well, you're not unsung if you've been featured on a postage stamp, are you?
[00:14:51]  I do that to make a point.
[00:14:53]  Most listeners have not heard of any of these women, and it's the rare listener indeed who's heard of more than one or two of them.
[00:15:00]  Yet we could rattle off the names of dozens of male scientists from years past, and you'd at least recognize most, if not all, of the names.
[00:15:09]  Friends, our telling of history and science remains unbalanced.
[00:15:14]  We do our future a grave disservice through this mischaracterization.
[00:15:18]  It's not enough to issue a stamp a quarter century after someone's death when their name is no longer one that'll be recognized.
[00:15:26]  We must not let any of our greats go unsung to begin with.
