The Elements of Marie Curie with Dava Sobel

Most people, when asked, name a famous female scientist, the only scientist they can name is Marie Curie.

First woman ever to teach at the University of Paris. So now she is really a phenomenon and a magnet for women scientists. There were about 45 women who worked for her.

45 women. This is a pivotal moment in the history of science.

It's a moment when physics and chemistry really meet.

And they meet society in a fundamental way. This is StarTalk. Neil deGrasse Tyson here, your personal astrophysicist. Got Chuck Nice with me, Chuckababy. Hey, Neil. Yeah, so guess who we have as a guest today? A very special guest? Let me tell you how special. Beyond special. Beyond special. Okay. Let me tell you how beyond special this person is right here. See her right here? Can we see all the cameras?

Okay.

There we go. David, welcome back to StarTalk. This person, sitting to my left, Our record show was our very first guest, season one, episode one of StarTalk. Whoa. Dava Sobel, we're unworthy.

We're not worthy.

You were there at the beginning. Oh my gosh. We call that telescopes that rocked our world. And back then it was only audio. That's all we had.

Okay.

Well, here we are.

That's like prehistory. So you're a science writer, but you cut your teeth as a journalist for, was it Gannett Papers in Long Island? What was it?

Oh, it was in upstate New York when I worked for them.

Them is Gannett, and Gannett is everywhere.

Right. It was the Binghamton Evening and Sunday Press.

Binghamton.

Wow.

Binghamton, a town in upstate New York.

And there was IBM there. I was there. Briefly, very briefly, a technical writer for IBM.

Okay, so you had some science chops early.

Yeah.

Okay.

I went to your high school, too.

Graduate of the Bronx High School of Science.

Whoa. Uh-oh. That's serious bona fides, as they say.

Okay, so you already had a science baptism becoming a journalist.

Yeah, yeah. Wow.

Yeah, and I didn't even know it was called science writing. And I wish somebody had told me about it sooner because it would have made my, journey a lot more direct. I was just a lost soul for a long time. But I'm happy now.

You've been found.

Saved by science. Saved by science.

I think most people came to know you through your, I don't know if it was your first book, but the first book that did really, really well, of course, and that was the Chronometer story.

Longitude.

Longitude, yes. The story, the subtitle. If you read the title in the subtitle of this book, you say, I ain't buying that. Who's going to be careful?

Exactly. I didn't think anybody would buy it.

Buy me the subtitle. What was it?

The True Story of a Lone Genius Who Solved the Greatest Scientific Problem of His Time.

Oh, no, I'm buying that book.

Wait, wait, wait.

Are you kidding me? That's like a scientific telenovela. Well, I know, but it's titled Longitude.

Longitude.

That's what I'm saying. You might have lost me there.

That's what I'm saying.

And people still ask me, What's it about, really?

It's hilarious.

And you wouldn't utter the man's name because no one heard of him, but Harrison?

John Harrison.

John Harrison, who invented the first seaworthy chronometer, which was a runaway mega bestseller, okay? Right. And another one, Galileo's daughter, yes, whose name was?

Well, she was Virginia. Oh. But then she became Suor Maria Celeste.

Celeste.

When she died. Celeste.

Celeste, yeah, that's the sky right there. Okay, okay. And then there was the glass ceiling.

Actually, it was called the glass universe.

Oh, the glass universe.

But, you know, even my editor called it the glass ceiling all the time.

Yeah, so that one was a good one. Let me just declare that my people are pretty well informed about that part of our own history in astronomy. There's a whole community of women at the Harvard College Observatory. But we knew that this story was not told beyond our own retelling among ourselves. And this was an important exposition of the role that women played in early science and particularly early astronomy. Yeah, the glass universe. And what was the subtitle on that one?

How the Laters of the Harvard Observatory Took the Measure of the Stars.

Ooh, nice.

Wow.

You make great titles.

Thank you.

So, we've got you here and now, because you have yet another book.

Yep.

Just setting the record straight.

Okay.

Just let's do it. Marie Curie.

Ooh.

Okay. Everyone knows. Wait, wait, wait. Okay. I'm not going to read the subtitle, because I want you to compliment her on yet another subtitle.

Okay.

Here it goes. Go ahead. Give it to us. Marie Curie.

How the glow of radium lit a path For women in science.

Oh, so you're just showing off now. You're just showing off. The glow of radium. The glow of radium. That's pretty wild, yeah. And I see what you did there, too, because she... Didn't she discover radium?

She did.

Right? She discovered radium and was it polonium? We'll get the whole thing. I'm sorry.

I'm just trying to remember my... Oh, you remember polonium?

Oh my God, thoughts about polonium.

Yeah, that was actually the first one.

Yeah, and so we can't name them all, you know, curium.

She didn't name any of them curium. That came later.

Yeah, and the first radioactive element was radium.

Well.

Uranium was the first one.

Oh, sure, sure.

But what she discovered, the first one was polonium.

So how many elements did she discover?

Two. Polonium and radium. Okay.

All right. And later on, we would name an element in her honor curium.

Curium.

Gotcha. So how did Marie Curie land in your lap?

I had almost a religious experience in the course of writing The Glass Universe. Because the story was all about women. And over and over, I kept finding myself surprised by what they had done. And I finally had to admit that I had embarrassingly low expectations of them. And even though I'm a woman, my mother was a scientist, I had all these reasons. True. had all of these reasons to be more respectful, I had just picked up the negative attitudes about women that were in the air.

You had a man bias.

I definitely did. And so it stunned me. And then I had several astronomers fact-check that book, and one of them was Alyssa Goodman at Harvard. And she... apologized right away. She said, I'm not really focusing on your descriptions of astrophysics because I'm so gobsmacked by these women. Here I am at Harvard. I know all their names, but I always thought it was something cute or quaint. I never realized they were doing science. So this kind of misogyny, these low opinions of women in science are very widespread, very insidious. And that made me want to tell more stories about women in science. So my editor immediately suggested Marie Curie. And I said no, because everybody knows about her, and I don't have anything new to say about her.

So I wouldn't want to just regurgitate facts. But then I was asked to review a book called Women and Their Element. And it was all about women chemists, more than 30 of them. And in reading the profiles of these women, six or seven of them had a direct connection to Marie Curie. And that was interesting. It was like a little network. So I got in touch with the Curie Museum in Paris, and they had records. There were about 45 women who worked for her. So this was something I knew that nobody knew about Madame Curie.

She was like the Harpo Studios of science before Oprah.

So they gave you access to these records?

Not just then. They actually had a book published, little sketches of the women in alphabetical order with some biographical details, and references to the papers they had written.

This is the stable of other women working in Marie Curie's laboratory.

Right.

Forty-five women.

Forty-five.

Man.

That's phenomenal.

How does it even get to that number?

Because of the position she was in. So she and her husband shared a Nobel Prize in 1903, and then he was killed in an accident, and she took over the laboratory. and his teaching position.

By the way, his name is Curie.

Yes, her name was Sklodowska.

Sklodowska, Yes, so she's Polish. Though we think of her as.

Think of her as French.

As French, right. Because of Madame Curie. Of course.

She had to go to Paris to go to university. Why? Because in Warsaw, where she was born, women were not allowed to attend university.

Wow.

Yeah.

And we're not talking about the 1600s.

She had a lot stacked against her. No, no. We're talking about the late 1800s. Yeah, yeah. First woman ever to teach at the University of Paris. Wow. So now she is really a phenomenon and a magnet for women scientists.

Oh, of course.

Oh, cool, yeah. All the other women in Poland who weren't allowed to go to school.

Some of those.

They were like, we're headed to Paris to study under Marie.

I didn't want to. undervalue the value of her visibility.

Yes.

In the ambitions of others. Oh my gosh.

Whereas I think women have always been interested in science, found ways to participate in science. She was the first one who really was in charge of a laboratory and a professorship.

Hey, StarTalk fans. I don't know if you know this, but the audio version of the podcast is actually post a week in advance of the video version. And you can get that in Spotify, Apple Podcasts, and most other podcast outlets that are out there. Multiple ways to ingest all that is cosmic on StarTalk. Okay, so today, most people, when asked, name a famous female scientist, the only scientist they can name is Marie Curie.

That is the sad truth, yes.

Okay, so you're not helping that matter because you just published a book on Marie Curie.

Guilty as charged.

So maybe the rest of these women, are there stories that can be highlighted among them?

Yes.

Oh, well. Yes. And is that also part.

Of the book?

That is what the book is about.

Oh.

It's about all these other women.

It's about the legacy. There you go. Yeah.

And it was during her lifetime. They came because of her and... Then she collaborated with them, published with them. She taught a course. So she was inspiring students in that class. Even before she taught at the university, she had taught at a teacher training school for women. And she taught physics.

Wow.

That was her field. So she shared the Nobel Prize in physics with Pierre.

In 1903.

But then in 1911, they awarded her, the Nobel Committee awarded her the Nobel Prize in Chemistry.

Wow.

And she alone. So she didn't share it with anyone.

Most Nobel Prizes are shared. Thank goodness that she did that.

Because, I mean, I hate to be cynical, but If you share a Nobel Prize with a husband, you also share his name.

And you have his name.

And people are going to automatically fall into the bias of, well, clearly she was his assistant.

He did the work. That happened. Even though she won a second Nobel Prize.

Even though she won.

It's really rough for women, let me tell you.

Man, that's tough.

That's why I was glad she won a second one, to erase any stigma that might have been attached.

Second one outright.

Yeah, this is all her.

No, it still got said that she was just his assistant.

Oh, man.

And the reason they took on that work, it was her dissertation project. When it got really interesting, Pierre quit what he was doing to work with her.

Just like a man.

Okay.

I didn't say that. No, I'm saying it.

But she had a good friend, a British physicist, Hertha Ayrton, who was also married to a physicist. And they intentionally worked on different things just so that no one could say that Hertha was her husband's assistant.

Just the assistant.

Yeah.

So highlight some of the science that came out of her lab and her brilliance.

Well, radioactivity, which was her word, was a new phenomenon. And that's why she got interested in it. So X-rays were discovered in 1895. And that was a huge interest. A thousand papers on X-rays got published.

That got the first Nobel Prize in physics. Wilhelm Röntgen. in 1900, the discovery of X-rays. What an unfortunate name. What, Wilhelm?

Wilhelm Röntgen.

Röntgen. In fact, we're the only ones who call them X-rays. Everybody else calls them Röntgen-rays.

Röntgen-rays, right.

What? You didn't know that?

No, I did not. I'm sorry, we got your Röntgens back. And it appears that your wrist is fractured. Yeah, that's not, that doesn't work for me, you know? We got your X-rays. I don't know, it just sounds great. What did Wilhelm call them?

He called them x-rays. So the very next year, Becquerel in France. Henri Becquerel.

That's a good name.

Multicultural we are. So he was curious about x-rays and wanted to see if maybe it was an effect of fluorescence or phosphorescence. But he noticed... And he was experimenting with a uranium crystal. And something else was coming out of the uranium that was not X-rays. And he got very interested in that. He called them uranic rays. And everybody else was so interested in X-rays that nobody picked up on the uranic rays. So Madame Curie, now looking for a a thesis topic, thought, that'll be good for me because it's interesting. And her husband was an inventor of instruments. Scientific instruments. Scientific instruments. And there was a way to measure the strength of these uranic rays that some of his instruments could pick up. So it just

seemed to be perfect for her. And soon she, so she started testing all the elements to see if anything else emitted these uranic rays. And she found out that thorium also did.

Named for?

You know, the god of the bifrost.

Thor. Thor. Yeah, it was a huge, fun history of culture and mythology and people embedded in the periodic table.

So thorium.

And then she was testing some uranium ore and got a reading that was far higher than either uranium or thorium. And so she concluded that there was an unknown element and as yet undiscovered element that she could discover on the basis of its radioactivity. That was her word.

Did you say that earlier that? This other ingredient is found with uranium?

With uranium, yes.

So that's pretty wild.

She inferred its existence because pure uranium wouldn't do that.

She'd already tested that. She knew what its strength was. And this was much, much higher. So first she retested everything, make sure she didn't make a mistake. And then she said, there has to be a new element. And this is part of the excitement of this period that the Periodic table was a work in progress.

It still is, but there are no gaps is the point.

There are no more gaps.

We're still increasing at the high end, making bigger, fatter elements. Like curium. There's a hypothesized place because all these elements are highly unstable, but there's an hypothesized place based on equations of atomic nuclei and their stability that we think there's an island of stability just a few more elements down.

If you make those elements, then they're permanent, and they won't decay, like all these other elements do. And so there's a hunt now for the island of stability. Yeah, so we're still working the table, but everything, you were talking about filling in gaps.

Filling in the gaps.

That were there.

Right.

Oh, yeah.

Right, there were a lot of gaps. And in the course of breaking down this ore to isolate the new element, she realized there were two different ones. and the first one they identified was Polonium which they named for.

Poland and then because of her because she was very fiercely Polish.

And had originally intended to get educated in Paris and then go back to Poland and teach and uplift her country people but She fell in love. A colleague of hers thought that he might be helpful to her in her work, and they fell in love. Neither of them expected that, but they did.

And what was her line?

Was her line? She wrote to one of her family members that it's a grief to me to remain forever.

In Paris, but I am deeply in love. Wow.

Today, there would just be an emoji. We lost all ability to communicate.

I want to say, she could really write. Her scientific papers are so clear. They are a marvel of clarity.

By the way, my wife would leave me for plane tickets to Paris. Much less a secret lover. No, I'm sorry. Just a plane ticket. She's like, listen, man, I'm sorry this didn't work out. It was good up till now.

Yeah, exactly. So I'm delighted we take so much for granted in modern times that the chart of boxes in the front of your chemistry class was complete.

Yeah, just been there forever.

It's like it's just there, endowed by the universe, but No, there's some hard work to make this happen. So tell me, no one understands at the time that radioactivity will harm healthy tissue. So give me some backstory on that.

Well, you'd think they would have figured it out right away because they had burns on their hands. And if they carried a vial of the stuff in a pocket, they got a burn on their body. So this immediately drew the attention of medical doctors. who saw this material as a treatment for cancer. And for several decades, radium was the cure for cancer.

For tumors, you would attack the cells of a tumor.

Exactly.

And it would destroy... It radiated the cells of the tumor.

Exactly.

Wow. How would they do? Would they drop radium into the tumor itself, or what would they do?

It changed over time. So the first two patients, two women with breast cancer, were actually brought into the Curie's laboratory... and had their.

So somebody had to have that thought to even consider this.

Right. There was harm associated with it, obviously, but it was doing so much good, and it was so interesting.

When did they find out that radioactivity also causes cancer?

Well, I think the real big moment was in the 1920s with the dial painters. So these were young women... painting the numbers on glow-in-the-dark watches and instruments using paint that actually contained radium. And they were told to put the paintbrush between their lips to get a nice point. And it destroyed their jaws and they died. Their teeth fell out.

It was horrible.

And of course, Madame Curie never advocated paint right full of radium that was not what she was.

Yeah but think about it think of how amazing it is that there's something that's glowing all by itself yeah that must have been just.

Stupefying yeah and that that appealed to marie and pierre from the beginning that as they would try to break down this ore and they'd have different dishes of of this or that they didn't know what it was at first, and at night there would be a glow. But it isn't really the radium, right? Even in the paint, the radium shoots out an alpha particle that excites the other ingredients in the paint, and that's what's glowing.

That's what renders it visible.

Yeah.

This is a pivotal moment in the history of science.

Absolutely.

In physics and chemistry.

Yeah.

Absolutely. Because it's not just.

And it's a moment when physics and chemistry really meet.

Meet and... they meet society in a fundamental way. Would you say that the concept of radioactivity and its value to dating things for their age all began with Marie Curie? Is that a fair credit to give? Yes.

She wasn't doing that work, but other people in her lab were, including some of the women.

Okay. Because if something is radioactive, you have a certain amount of that substance in your sample. If it's radioactive, it's changing identity. It's becoming another element. It's very alchemical, isn't it? Look at that.

Which was a big problem at first.

Changing one element into another, is that even possible?

Right.

Because we'd already given up on alchemy.

Exactly.

If you know the rate at which it's changing, and you know how much you started with, you'll know how old the sample is because of how long it's been there. Yeah, and oh my gosh, how useful that is, especially to geologists.

Yes, the age of the Earth was determined in the wake of these discoveries.

Cool.

And it was much older than anybody had thought.

Older than 6,000 years.

You think?

That's so funny.

Tell me about her second Nobel Prize. What was she cited for in that? The one in chemistry.

Specifically for the discoveries of the new elements and her isolation of radium, which she had only recently managed to do. So these elements existed in such tiny quantities. From a ton of ore, she would get a fraction of a gram.

You know how much a gram weighs? How big is the cracker? No, I don't know.

How much is a gram?

It's hardly anything. It's one-thirtieth... Of one ounce. One thirtieth of an ounce.

Yes. See, that is information, as a proud American, that I will never need.

Have you ever wanted one of your questions on the universe answered? We all have questions about the universe. From black holes to quasars, quantum entanglement, wormholes, there is no end to the depths of cosmic curiosity. Well, the entry level of Patreon membership with StarTalk gets you just that.

I think it starts at $ 5 a month. You have access to the question line that reaches our Cosmic Query programming. And not only that, we produce a special Cosmic Queries installment just for For Patreon members.

Because if you weren't the director of the Hayden Planetarium, what do you think you would be doing?

But this would have to be another universe. It wouldn't happen in this universe. Okay. I'd be a songwriter for Broadway musicals.

Ooh!

So, that's the entry level, and the perks ascend from there. There's a level, in fact, where... We send you an autographed copy of one of my latest books. Right now, it's Starry Messenger, Cosmic Perspectives on Civilization. And it's signed with my fancy fountain pen with purple ink. So I invite you to just check the link below. And all of that money goes to our ability to experiment with new ways of bringing the universe down to Earth. So thank you for those who have already joined. And we welcome others to participate in this grand adventure of what it is to bring the universe down to earth. As always, keep looking up. Tell me about her daughter.

Oh.

What's up with that?

So she had two daughters. And the older girl was very much like her father. And Marie always dreamed that she would become a scientist, which she did. And she also won a Nobel Prize in chemistry.

Wow.

Damn. Talk about a bloodline right there. Yeah. So when was the daughter's Nobel Prize? 1935.

And what'd she do it for? She and her husband found a way to create.

Uh-oh.

The husband is in there.

There's another husband. She repeated the story. Married the lab partner, worked together.

Wow.

And made these tremendous discoveries and shared the Nobel Prize with him.

Look at that. You have become your mother.

Yeah.

So what did she discover?

They discovered a way to make artificial radio elements, which had a big advantage over natural radioactive elements because they would decay to something non-radioactive immediately. So they could make safer tracers.

Wow. Very important in medicine.

In medicine, exactly, exactly. So you don't really want to be using radium to treat your cancer.

That's fascinating.

Yeah, because not all elements are created equal. Oh, yeah. Some decay faster than others. Right. Yeah, so that their lethality or their harm factor drops exponentially from when you needed it at its peak. Right. And so, yeah. In fact, depending on how long you need the treatment, they just pull one off the shelf that has the right radioactive profile. Absolutely. Right, right.

So she's creating the ideas... and the foundations for whatever medical instruments would later be built in the service of human health.

So the people who got the Nobel Prize for those discoveries, basically she would call them and go, you're welcome.

That's how science builds on itself.

Yes, yes.

Did you want to talk about the love affair?

So by the time of her second Nobel Prize, her husband's gone.

He's deceased he was yes five years.

Gone and from what I understand, there was some highly written about in the media affair between her and a married man. Do I remember this correctly? Yes. Okay. And today, I don't know how important that would be to anybody. So in the late aughts, OK, early 1910s, that information is received differently. Now, she's a celebrity. So everyone is going to care about her sex life. OK, because that's what we do. That's how that goes. So did this matter to the Nobel Committee? Were they?

It mattered to everyone. She was vilified. She was called a homewrecker and a foreigner. because he was a married man with children. So word of this got out, and it got out in the wake of a highly important physics meeting where only the top physicists in the world were invited to attend. She was there. She was the only woman in the room. And they come out. Albert Einstein was there. Ernest Rutherford, a few people you've heard of.

Rutherford discovered the nucleus of the atom. These are some heavy hitters. Big time. So she's vilified, and the cheating husband is not vilified.

Right. Right, he's a victim.

Oh, he's a victim.

Oh.

It's the harlot scientist.

Of course. No, she's a foreigner, and she had recently tried to gain election to the Academy of Sciences.

So people get jingoistic. She's a foreigner. She's a homewrecker. A man married with kids. He's a victim. So what happened at the meeting and then what happened with the Nobel Committee?

The meeting was already over and Einstein wrote to her outraged that she had been pinpointed this way and said he's sorry that the rabble was concerning itself, and he thought very highly of her.

Yeah. See, that's great, because his deal is, what does any of this have to do with science?

The Nobel Committee decided that maybe it would not be a good idea for her to come to Stockholm to accept the prize in the midst of this scandal.

Would they have given her the prize even if he didn't show up?

I think so, but I can't.

They didn't want the optics. Just the whole, or the circus that would unfold. Right. Because they wouldn't be asking about, that would change the mood of the ceremony.

Of the ceremony. But at that, and she had offered at first not to come. And they told her, no, no one here believes the lies. But then they changed their minds and asked her not to come. And she said, I fail to see any connection between between my scientific work and scandalous attacks on my private life. And she went to Stockholm.

However, I will say that the illicit sex that I've had with my lab partner is indeed radioactive.

Oh, stop.

No comment.

There's a novel inside Chuck somewhere. I'm trying to get that out. So she went and got the prize.

She got the prize, yeah. And she took her daughter with her. So Iran got a foretaste of her.

Hey, I'm going to think I'm going to come by here in 20 years.

I'm going to come back. 25 years, I'll be back.

I'll be back. Watch me. So your book, who published the book?

Grove Atlantic Monthly Press.

Oh, okay. And it's out now?

It is.

It is out now. All right, so... Is this a movie ready to be made? Sounds like one. Did someone buy the movie rights?

From your lips, Neil.

I saw recently a play about Marie Curie.

Yes, there have been plays, there have been movies. But as I said, this is a different story. We'll see what happens. Do you remember her on the mural? Of course you do.

The huge mosaic at the front entrance of the Bronx High School of Science. You walk under that every single day. And it's very biblical in its scale and in the posturing of the characters. And every single character is a mathematician, a scientist, or an engineer. And one of them is Marie Curie, prominently featured.

And she's the only woman there.

And she's there looking at a test tube or something chemical. And we've got like a Galileo figure, a Newton, we have Imhotep, architect of ancient Egypt, all these folk. And you walk under that every day and you say, yeah.

One day I'm going to be on that mural.

It's cool.

That's fantastic.

It seems to me everything Marie Curie touched in and around her lab might still be radioactive today.

Yes.

Is that true?

I'm sure it is.

Okay, how about her notes, her clothing, her effects?

Yeah.

Radium has a half-life of 1,600 years.

Oh, well, there you have it. That's it. 1,600 years. To remind people about half-life, so whatever how much radium you have today, in 1,600 years, you have half that much. Right.

And then 1,600 years, you have half of that.

Half of that. So 3,200 years, you'll have one-fourth of what's sitting in front of you right now. So clearly that's... So you day it. What did she die of?

She died of aplastic anemia, so her body could no longer create red blood cells. Partly radioactivity exposure, but also X-ray exposure. Because during World War I, she outfitted a van with X-ray equipment and drove to the front because it was going to be the first time that battle wounds could be X-rayed.

She created a mobile x-ray unit?

She did.

Wow.

It was instantly obvious what the value of x-rays were when they were discovered.

Even so, she had to argue with some of the doctors who had never seen it because it was still relatively new.

Okay.

And so she created this car that had all the equipment. And then, because people were very quickly convinced and were willing to have have something permanent wherever the field hospitals were. So she set up a course. She created a six-week course in x-ray, electricity, human anatomy, and she trained 150 French women to do that same work.

Wow.

So every x-ray technician owes her a debt because she created their job.

Yes.

Well, there were some before that, but they were, coming up through the medical ranks, her feeling was, this is a crisis, and there are a lot of women who want to help. Women are not on the front. I can tell them what they need to know, and they can go and do it.

It's amazing because you learn about Marie Curie, and they just say radioactivity, they say.

That, Just the short list. The short list.

They're like, radioactivity, Nobel Prize, woman scientist, and moving on. You know, like, that's it. This is, I mean, I'm just absolutely gobsmacked by all the accomplishments of this woman and what she's responsible for.

When I started this book, the pandemic happened. So I didn't get to go to Paris. But what I discovered was that everything about Madame Curie has been digitized. So her personal notebooks, the most touching of which is the grief journal she kept for a year after her husband's death, in which she spoke to him. You can read the whole thing online.

So you had access to digital records, so you didn't have to expose yourself to what might be residual radium.

Well, I couldn't even have the grief of going to Paris, you know. It was what I had to settle for.

But I was....

Fascinated by the wealth of the material. You can read all of the weekly publications of the Academy of Sciences back centuries, and it's easy to get at. And then for.

Notebooks, yes.

Okay. You sold me.

It's just free.

You had me at free.

Get up your French reading.

Is the only thing. Oh, it's all in French.

Yeah.

Okay.

Good book, of course. Yeah, it was interesting. Yeah, unless it's just English and a really bad French accent, I'm screwed.

He does a Frenchman bad accent really well.

I bet, I bet, yeah.

And you always give them a cigarette.

You have to have a cigarette, okay? It is French law. You do not want me to be arrested.

How soon we forget. or perhaps never knew, or worse yet, suppressed the contributions of so many people, so many scientists, engineers, seekers of cosmic truths, be it in a laboratory or in the sky, anywhere. The number of people represented in that population is huge yet we only ever read about a few of them here and there and somehow some of us are prone to think the information, knowledge, discovery just somehow is handed to us from on high from a tablet in the sky no, it's hard work and scientists who are committed have done this often without reward.

The only reward is the act of discovery and the knowledge that the universe is knowable and you on the frontier, on that moving frontier, have contributed to that base of knowledge that we call science. Marie Curie, among others, and all the women in her lab and all the other labs that we have yet to hear about because Deva Sobel hasn't written about them yet. Who knows how many labs lurk in our ignorance for us to get a full appreciation of the foundations of what we take for granted as modern science. And that is a cosmic perspective.

So Deva, our first ever StarTalk guest, I want you to come back for every book that you write.

I want to write another one just for that.

If you need incentive to go back to StarTalk, write another damn book.

I got it.

Okay.

You got it. Thanks for being on the show. Chuck, good to have you, man.

Always a pleasure.

All right. This has been StarTalk with our inaugural guest returning, coming back to us in this, the 600th episode of what she started as episode number one, Deva Sobel.

Wow.

Thanks for coming back. Neil Tyson here, your personal astrophysicist. As always, keep looking up.
