01: John Gottman - How to Be a Master of Relationship. Welcome! My guest today is Dr. John Gottman, one of the world's leading experts on how to have an amazing relationship. He and his wife Julie currently operate The Gottman Institute in Seattle, offering numerous resources and training. Join us for a deep dive into their work! Dr. Gottman’s findings are largely based on the conclusions he has made over many years of research and observations of couples. He and his team have how to be a master (and avoid being a disaster) at relationship. Dr. Gottman discusses the following topics: “The Sound Relationship House” - what is the foundation for a relationship that lasts? Learn the importance of having high expectations in relationship, and also uncover ways in which what you'd *think* would be good for your relationship is actually counterproductive. Dr. Gottman identifies Styles of Confronting Conflict: Volatile, Validating, and Conflict-Avoiding. All of these conflict styles can lead to successful relationships. Learn what to do if you and your partner are mismatched in your conflict style. Dr. Gottman discusses “bids” we make with our partner as an attempt to connect. Are you a "yes" to your partner's bids? Are they a yes to yours? “Bids” that fail are often the beginnings of conflict. How do things change if you start paying attention and responding to your partner's bids in a positive way? Mindfulness is the key to noticing these bids and avoiding conflict. “Small Things Often” - a reminder to turn toward these bids in the small moments of life. Dr. Gottman's concept of startup is a way of thinking about what you bring to your interactions with your partner. Do you start in a place that's already positive, and thinking highly of your partner? Or do you start in a place where you are suspecting the worst of your partner? Build up your emotional bank account with small compliments (deposits). According to John, there are three phases of any relationship: Falling in Love (initial), Building Trust (middle), and Cherishing Your Partner (long-term intimacy). What phase are you in? The key to success is using strategies that are appropriate for where you are in your relationship. The key to more sex is having the freedom to say "no" without being punished for it. If refusing sex can actually have a positive payoff, then it will actually lead to a couple having a more satisfying (and frequent) sex life. Do you ever wonder how to make a good relationship GREAT? Focus on cherishing your partner. What if YOU are the only partner who wants to make changes? Can you make a difference? Absolutely. Learn how shifts in your approach can have a profound affect on your relationship. The key to success in a relationship isn't that nothing bad ever happens. It's how well you as a couple learn how to repair after those things occur. John discusses how you can learn to repair, and the positive effects that has on long-term relationships. Do you know how to decide if you’re in a bad relationship? When you're with your partner, are you at your best? Or are you veering off towards your worst? Gottman offers this simple guideline for how to know whether to stay or go. Also what to think about BEFORE you decide that you're on the wrong path. Join us for these topics and more.

Rank #1: (Natural) Childbirth. Our producer is pregnant. For the past nine months people have asked what her birth plan is, which to her seems like asking what kind of weather she had planned for her wedding day. “All of a sudden my life was full of these terms: natural, medicated, doula, epidural, and it quickly became clear that there was a great debate—and I was supposed to choose a side.” We wanted to know when this controversy started, and why comedian Amy Schumer is joking about sea-turtle births. So we talked to Lara Freidenfelds, a historian of sexuality, reproduction, and women’s health in America, and learned some surprising things about our nation’s early childbirth practices. Freidenfelds also shared her views about why a growing number of women are opting for unmedicated births, while Amy Tuteur, a retired obstetrician and the author of Push Back: Guilt in the Age of Natural Parenting, tells us that once upon a time all births were natural—and a lot of mothers and babies died.

Rank #2: The Ancient Chemistry Inside Your Taco. When you bite into a taco, quesadilla, or anything else involving a traditionally made corn tortilla, your taste buds get to experience the results of an ancient chemical process called nixtamalization. The technique dates to around 1500 BCE and involves cooking corn kernels with an alkaline substance, like lime or wood ash, which makes the dough softer, tastier, and much more nutritious. Only in the 20th century did scientists figure out the secret of nixtamalization—the process releases niacin, one of the essential B vitamins. Our guest, archaeologist and nixtamalization expert Rachel Briggs, says that the historical chemical process transformed corn from a regular food into a viable dietary staple, one that cultures around the world continue to rely on for many of their calories. Without nixtamalization Mesoamerican civilizations like the Maya and the Aztec would not have survived, let alone flourished. Benjamin Miller and Christina Martinez are the only chefs in Philadelphia making their tortillas from scratch. Our associate producer, Rigoberto Hernandez, visited the couple at their traditional Mexican restaurant in South Philadelphia to find out why they’re so dedicated to handmade tortillas—and to see the nixtamalization process in action.

Rank #1: 304 – The Past, Present and Future of Fusion Energy. Justin and Jason wrote a nice book on fusion called The Future of Fusion Energy, and this episode is based on this book. We start out by revisiting the breakthroughs that drove progress in fusion over the decades, including understanding stars, the tokamak, superconducting magnets, supercomputers and a number of specific aspects of plasma physics. We then look at the current state of fusion research as well as where it might go.
Rank #2: 270 – Nuclear Weapons. In this episode we chat about the science and engineering involved in nuclear weapons. Our guest is Alex Wellerstein of the Stevens Institute of Technology. We talk about atomic bombs as well as hydrogen bombs, how to refine the necessary fuels as well as a little bit of history.
Rank #1: Lacerta. A star doesn’t have to be big to be brash. Indeed, some of the most active stars are also some of the smallest. An example is in Lacerta, the lizard. The constellation is high in the northeast at nightfall. It’s not much to look at — only a few puny stars outline the lizard’s profile. But about a decade ago, one of its stars really showed off. It produced the most powerful stellar flare seen to that time — thousands of times more powerful than anything the Sun has generated. Flares are massive explosions. They occur when lines of magnetic force get tangled, then snap. Some of the biggest happen in little stars. EV Lacertae, for example, is a red dwarf. It’s only about a third as massive as the Sun, and just one percent as bright. A red dwarf is different from stars like the Sun. Hot gas bubbles from its core all the way to the surface. The gas is electrically charged. So as it churns, it generates a strong magnetic field. And EV Lacertae is quite young, so it spins faster than the Sun does. That amps up the magnetic field even more. With a faster-spinning magnetic field, the lines are bound to get more tangled. And when they snap, they do so with a jolt — a giant flare. It blasts energy and particles into space. If the Sun zapped Earth with such a flare, it could knock out everything from cell phones to power grids — decimating our technology in an instant. We’ll talk about an even more powerful object in Lacerta tomorrow. Script by Damond Benningfield
Rank #2: Changing Sun. The Sun is going through a big change. One cycle of activity is ending, while another is just beginning. Neither cycle is very active, though. In fact, the Sun probably is entering an unusually quiet year. There may be times when we won’t see anything going on at all. The Sun follows a magnetic cycle that reaches its peak every 11 years or so. At the peak, the Sun produces lots of the dark magnetic storms known as sunspots. It also produces more outbursts of energy and particles. Right now, the Sun is at the end of one cycle and the start of another. The ending one has been well below normal. In fact, there were many days where astronomers saw no sunspots at all. And the next cycle is expected to be even calmer. Hints of the new cycle were seen as early as 2016. But the first strong indication came this July. A sunspot that lasted for a few days had the opposite magnetic polarity of the previous ones — a sure sign that it belongs to a new cycle. For the next year, though, we’re expected to remain at solar minimum — a time when the Sun is especially quiet. Solar minimum is a good thing for our technology. Solar storms can harm satellites, force airlines to reroute flights, and knock out power grids on Earth. That’s less likely to happen during solar minimum — although individual storms can still be nasty. The new cycle should begin to ramp up by late next year, and reach its peak a few years later — one more change for our always-changing star. Script by Damond Benningfield
Rank #1: What is Mechanical Engineering? - Episode 105. Are you thinking about getting into engineering but don't know what flavor is right for you? The answer is simple: Mechanical Engineering. Sure, just because we are a couple of ME's might make us biased, but it does make sense. Job opportunity is high, pay is good, work is interesting...or at least it potentially can be. NASA, Boeing, SpaceX. They all need Mechanical Engineers!In this episode we break down what it takes to be a ME, looking through the courses you would have to take, the types of jobs you would land, the pay you could expect, and settle the debate once and for all that ME is the superior engineering degree.
Rank #2: What Is Aerospace Engineering? - Episode 155. Thinking about getting a degree in engineering, but not sure what path to take? Maybe Mechanical Engineering's little brother, Aerospace, is right for you! We take a look at some of the areas of focus involved with Aerospace Engineering, discuss the differences between Aeronatical and Astronautical Engineering, look into companies that hire AEs, talk about the day-to-day of the job, which colleges rate the highest, and most importantly how much cash money you will make!

Rank #1: What Exxon Knew and When They Knew It: Climate Science in S.F. Federal Court. It’s not a trial, nor is it quite a debate, but what’s happening Wednesday in Judge William Alsup’s federal courtroom is an unusual and possibly unprecedented proceeding. That’s because Alsup has ordered a four-hour tutorial on climate change – what scientists know about global warming, and when they knew it. And it’s because of who’s responsible for the tutorial: Bay Area cities on one side, and oil companies on the other. The cities sued the oil companies over the impacts of sea level rise, and the tutorial is a key early step in the case, one of dozens of similar cases across the country. Lawyers for San Francisco and Oakland claim BP, Exxon, Chevron and others created a public nuisance to the Bay Area by producing and selling oil and gas while misleading the public about known consequences. The two Bay Area cases represent one strategy among several in a growing body of law relying on tort and common-law claims to hold fossil fuel producers responsible for global warming. Complicating these arguments are the other human activities that also contribute to global warming – and the fact that fossil fuel burning is global, which means companies and countries in the oil and gas industry outside of California are responsible. “And that’s why probably there’s going to be a big focus on the fraud part: who was overtly and aggressively denying the science, who knew internally,” says Stanford University historian of science Robert N. Proctor. “There’s a lot of evidence that some of these fossil fuel makers really did know quite a while ago that there was going to be this threat but they covered it up.” Proctor says the cases resemble efforts to hold major tobacco producers responsible for smoking-related lung cancer. “Both of these industries– tobacco and big carbon – have been kind of embracing science and a sense of open inquiry,” he says, “with the idea being that as long as we leave the inquiry open we can maximize uncertainty and say that we don’t really know the truth.” Alsup has issued a list of questions he wants answered in the presentations. They include the cause of the ice ages, the origins of carbon dioxide in the atmosphere, and even whether billions of peoples’ breathing is warming up the planet. “These questions are great questions, they’re interesting questions, but they’re not the questions that you would want to say, ‘What’s the state of knowledge?’” says Katherine Mach, a Stanford researcher whose work focuses on assessing climate science. Mach and other scientists characterized the questions as simple, and straightforward. They’re also pretty easy to answer for scientists. “Turns out answers to those questions are actually pretty well known,” wrote Andrew Dressler, a climate scientist at Texas A&M. Dressler has sketched out his responses on Twitter. https://twitter.com/AndrewDessler/status/971818482915532800 At the website Real Climate, scientists are compiling and updating crowdsourced responses. The semi-adversarial nature of the tutorial has reminded some observers of an idea circulated last year, by NYU professor Steven Koonin and then by Environmental Protection Agency Administrator Scott Pruitt, that climate science should be the subject of an intellectual “red team-blue team” exercise, that name taken from military simulations in which one side attacks another. But Wednesday’s briefing is fundamentally different, for at least a few reasons: the judge has wide latitude in using the information presented there, and these days, it’s more likely that the science presented by cities and oil companies will overlap or even agree. Fossil fuel companies now characterize themselves as active but risk-adverse participants in the global discussion about climate science – and these companies have acknowledged risks posed by climate change in public statements. ExxonMobil, for example, states on its website that it “unequivocally reject[s] allegations that [it] suppressed climate change research contained in media reports that are inaccurate distortions of [the company’s] nearly 40-year history of climate research.” But each side has its own time to present the best climate science, and its own version of history. Experts say that format means key differences may emerge in questions around certainty, both past and present. Cities, for their part, are likely to emphasize growing certainty in climate research. “What we’ve seen over the last 5-10 years is an incredible amount of research into the science of detection and attribution,” says Aaron Strong, an associate professor of ocean science at the University of Maine. “There are a lot of uncertainties in terms of of future projection of sea level rise, but there’s not a lot of uncertainty in the fact that it’s rising at all.”
Rank #2: 40 Years With the Voyager Spacecraft: Earth’s Most Distant Explorers Are Still Calling Home. When NASA’s Voyager 1 and 2 spacecraft left Earth in 1977, they had a mission that was possible only at that very moment in human history. The spacecraft were headed toward two of the outer planets of our solar system, and would use the gravity of one planet to swing themselves toward the next. It’s the alignment of Jupiter, Saturn, Uranus, and Neptune that make this gravity swing dance possible. This alignment happens only once every 176 years, and it happened just at the time when human space technology was ready to meet the challenge. ‘None of us knew how long they would last. At the time the space age was only 20 years old.’Ed Stone, NASA When it comes to the Voyager mission, the numbers themselves are cosmic. Voyager 1 is 13 billion miles away from Earth, and counting. Voyager 1 and 2 discovered “The Great Dark Spot” on Neptune and the first active volcanoes on another planet — on Jupiter’s moon, Io. In 2012, Voyager 1 passed across the far end of our solar system to give humanity its first taste of interstellar space. These were not among the outcomes Ed Stone could have imagined when he and his colleagues at NASA’s Jet Propulsion Laboratory prepped the two Voyagers for launch in 1977. Their mission was a four-year sortie to Jupiter and Saturn — which at the time seemed plenty ambitious. The moon landing was still a fresh memory. Now in his 80s, Professor Stone, a physicist and National Medal of Science recipient, continues to serve as chief scientist for the program he helped launch. He is also a full-time professor and researcher at Caltech. He spoke with KQED News host Devin Katayama on the occasion of Voyager’s 40th anniversary. Katayama: Professor Stone, you were in your early forties when Voyager 1 and 2 launched into space. What was the original goal of that mission? [contextly_sidebar id=”yXuyMK6hQ5u1hDrzZYCw6oNaNoQkfCrz”]Stone: The original goal was a four-year mission to Jupiter and Saturn and Titan, a moon of Saturn. And we had two spacecraft to give us a higher probability of having at least one making it on that four-year journey to Saturn. Katayama: So did you ever think the Voyager spacecrafts would last this long? Stone: None of us knew how long they would last. At the time the space age was only 20 years old. Katayama: So, 40 years later, what are some of the most important planetary discoveries to date, thanks to the Voyager mission? Stone: Well, we discovered that nature is much more diverse than we could have imagined. For instance, before Voyager, the only known active volcanoes were here on Earth. And then we found a moon of Jupiter called Io, about the size of our moon, which has ten times more volcanic activity than Earth. So time after time, we’ve discovered that our ‘terracentric’ view of planets and magnetic fields and moons and rings was much too limited. Katayama: People working in the field might not be surprised to discover how expansive space could be, but has it changed our understanding of the universe? Stone: We now understand that when bodies form, there are processes by which they can maintain a very active geological life, just as the Earth does. And the way that happens depends on the exact circumstances. So each moon seems to be quite distinct in character. Katayama: NASA put a message on Voyager for other civilizations in outer space that might one day find it — The Golden Record. What was the thinking behind that? Stone: It was a form of outreach. It was a declaration that we as a society here on Earth could actually send such a message, which would leave the sun, the solar system, and orbit the center of the Milky Way galaxy for billions of years, long after Earth itself may have ceased to exist. The Golden Record is carried on board the Voyager 1 and 2 spacecrafts. (NASA) Katayama: Can you share with us what that message was? Stone: There were several messages: greetings from different languages on Earth, messages from different cultures, images of various aspects of Earth. The whole idea was to make this a time capsule, or what I call a calling card: the ambassadors Earth has sent to the Milky Way galaxy. Katayama: I’m curious whether you had any say in what that messaging was. Stone: The messaging was really determined by Carl Sagan and a small group that he put together. They did this basically over a 6-month period before launch, and it was done independently of what we were all doing, getting ready for launch. Katayama: I’m curious whether there are any questions you were hoping would be answered by Voyager that have not been answered. Stone: I think what Voyager has done is inform us well enough to know what interesting questions to ask now. For instance, before Voyager, the only known liquid water was here on Earth, in the ocean. Then we flew by Europa, another moon of Jupiter, which has an icy crust on it which is cracked — very much like ice on an ocean. In fact, that’s what a subsequent mission, Galileo, has shown. Katayama: The Voyager spacecraft are steadily losing power, and I saw a prediction that NASA will have to turn off all the equipment by 2030. What do you think should come next in terms of probing interstellar space? Stone: The next step is exploring the heliosphere itself, which is the huge bubble that Voyager left in August 2012. That is going to be done by a mission here on Earth which looks at neutral atoms coming from the outer edges of the heliosphere and from the interstellar medium beyond. That mission is now being launched in 2024. It would be the next stage in understanding the heliospheric bubble that protects all the planets in the solar system, and its interaction with the winds of the other stars as it occurs in interstellar space. Katayama: What are the biggest questions about the heliosphere that we need to understand? Stone: We need to understand the size of the heliosphere, because it breathes in and out with the 11-year solar cycle. But it will also change size as the material outside in interstellar space changes over a much longer time scale. So it’s understanding how our solar bubble, which envelops the Earth, interacts and changes as what’s in interstellar space also changes. Katayama: What does communication between us here on Earth and the Voyager spacecraft look like? Stone: We listen 24 hours a day; the spacecraft each have a 21-watt transmitter. We get a very slow data rate — it’s 160 bits per second, which is the best we can get from 13 billion miles away. Katayama: What’s it been like having a hand in such an important mission, and having spent most of your career with Voyager? Stone: It’s been a remarkable journey. Science is about learning about nature — why it’s there, why it is the way it is. And Voyager has been an overwhelming success in terms of scientific endeavor. But even more than that, the thing that’s wonderful about Voyager is it’s remarkably inspiring to many people, and that’s of great value as well. It turned out to be a very effective way of involving the greater public in the journey, which is a scientific journey of discovery. Want more Voyager action?

Rank #1: Their Favorite Theorem. Have you ever wondered what mathematicans’ favorite theorems were? How about what food or music pairs perfectly with those theorems? Well whether your answer to those questions was yes or no or what are you talking about there is a new mathematics podcast on the scene you need to check out called My Favorite Theorem. My Favorite Theorem is the brain child of Kevin Knudson and Evelyn Lamb. You may recognize those names as a writer who contributes to The Conversation, Forbes, and is a mathematics professor at the University of Florida and as freelance mathematics journalist who runs the Scientific American blog Roots of Unity. They were kind enough to talk to me early in the morning about where the idea for the show came from, why the pairings are so cool, and how mathematical audio can help humanize mathematicians. Oh, and I make them come up with a pairing for our conversation. Plus, as a super special bonus they were kind enough to let me share episode 3 of My Favorite Theorem with Emille Davie Lawrence as part of the episode.

Rank #2: f(θ)=1-sin(θ). f(θ)=1-sin(θ) If you ever want to conduct a quick social experiment on the status of mathematics in the world just get yourself a dating profile and mention on it that you are a mathematician. The messages you get will be quite illuminating: “I hate to break it to you, but while I appreciate math for its logic and beauty, I don’t think I’ll ever like it. lol TOO many formulas.” “I got up to AP Calc during my senior year of high school, cheated off my best friend on all the tests and still got 70s in the class, and swore off math from thereon.” Even when people do not say outright that they despise math the contents can leave a bit to be desired: “I’m awful at math but it fascinates me–much like historical linguistics and conjugating Russian.” It is not like it was all bad though. Samuel did once get this message: “I also really like math and spend a lot of time trying to figure out how to get people to like it more!” But come to think of it he doesn’t think they actually ended up actually going on a date. We really shouldn’t be so negative about all of this. Samuel has been told by more than one person that being a mathematician makes him sexy, really he has and it is so validating for him, and he doubts anyone ever turned me down for a date just because he loves mathematics. But given all the times he has received messages with gloomy words about math and how often on a first date some of the first words out of his companion’s mouth is how much they hate math he couldn’t help but wonder if mathematics has impacted my dating life negatively, if only a little bit. Of course mathematics has never let us down in the past, doubt it is going to start now.

So when Planet Money called her up and asked if she would be interested in getting some dating advice from economist Tim Harford she definitely said yes. Samuel spoke with Andrea about what it was like to follow an economist’s advice on dating, why we should not treat dating like a job, and where to draw the line when it comes to formulaic dating. Helping you Math your way to Someone Special Back in 2009 for the podcast Strongly Connected Components Samuel interviewed Sam Yagan then the CEO and co-founder of an upstart online dating site which was differentiating itself from the competition by putting a real focus on the data side of dating. That little upstart was OKCupid and Sam is now the CEO of Match Group, which includes Match.com, OkCupid and Tinder. They talked about why OKCupid puts such a focus on math and data, how the OKCupid algorithm relies on its users, and why you shouldn’t stress out on having the perfect dating profile photo.
