Misinformation, AI, & Science Photography
Science photographer Felice Frankel is acclaimed for the striking beauty of her images, which have been displayed in museums, published in multiple books, and even featured in the background in one of Ang Lee’s films. Yet she insists that she doesn’t think of herself as an artist. Her academic background is in biology, she began her working life doing cancer research at Columbia University, and sh
Special Episode: Collaborating with Community Colleges
MIT OpenCourseWare has been one of the pioneers of open education, leading the way by offering free materials from MIT courses as early as 2001, when no other institutions were pursuing comparably ambitious initiatives. But in subsequent years, there’s been an explosion of activity in open education, led by faculty members, instructional designers, and librarians at institutions throughout the Uni
MIT Economist Jon Gruber on AI, Trade-offs & Healthcare
Prof. Jonathan Gruber, our guest for this episode, likes to tell his students that economics is a fundamentally right-wing science. What he means by that is that classical economics is built on one powerful explanatory insight: that free markets—networks of buyers and sellers, producers and consumers, weighing the trade-offs of different options and making self-interested choices based on supply a
MIT Programmer Ana Bell on Growth Mindset, Coding, and Rubber Ducks
Learn about Python, growth mindset, and the uses of rubber ducks in this interview with MIT lecturer Ana Bell. Dr. Bell, who has been programming since she was twelve and now teaches popular introductory courses in computer science, says that coding consists of almost equal parts creativity and logic. The creative part, she explains, gets exercised particularly when you have to come up with an alg
MIT Economist Andrew W. Lo on Finance, AI, and Human Behavior
In this the first of two pilot episodes of Chalk Radio with VIDEO, Professor Andrew Lo, who teaches finance at MIT’s Sloan School of Management, knows that many people find financial matters perplexing and scary. Lots of us don’t have a good head for numbers, and besides, how can one get advice and make sound decisions when it’s taboo to discuss one’s finances at all? That’s where a financial advi
Sujood from Sudan: An Open Learner's Story
Sujood Khalid Eldouma recently relocated to the UK for her master’s studies, having previously lived in Egypt after fleeing her native Sudan to escape the devastating civil war in that country. Sujood holds a bachelor’s degree in electrical engineering from the University of Khartoum, but her ambitions extend far beyond the field she was trained in. She recently graduated from the MIT Emerging Tal
Jerry from Uganda: An Open Learner's Story
They say every crisis also presents an opportunity. Open learner Jerry Vance Anguzu seized one such opportunity in the midst of the Covid-19 pandemic, when his native country of Uganda went into lockdown. Jerry was stuck at home, unable to earn a living, but that enforced inactivity gave him the chance to pursue new directions in his education. A few years earlier, he had discovered MIT OpenCourse
Lotfullah from Afghanistan: An Open Learner's Story
Our guest for this episode, Lotfullah Andishmand, grew up in a village in rural Afghanistan where there was no internet access or electric lights. (He describes having had to navigate by moonlight to get to his uncle’s house for tutoring in chemistry.) In search of educational opportunity, he eventually moved to Kabul, where he discovered MIT OpenCourseWare’s lecture videos while studying electric
Nader from Jordan: An Open Learner's Story
When Nader AlEtaywi was in high school in Jordan, he had a passion for finance but his prospects seemed limited. Juggling his studies, minimum-wage jobs, and family crises made it hard to envision a future where he could develop his talents and flourish in his chosen field. Through sheer perseverance he finished high school and entered university, where during the Covid pandemic in late 2020 he di
Jae-Min from South Korea: An Open Learner’s Story
Jae-Min Hong, our guest for this episode, is a hungry learner with wide-ranging curiosity and a distrust of groupthink. A native of South Korea, she has been fluent in English from childhood, which has opened up many educational possibilities for her.

(She originally went into cognitive neuroscience because, as she pu
Innovation, Past and Future with Open Learning's Dean Christopher Capozzola
As MIT’s Senior Associate Dean for Open Learning, Christopher Capozzola’s job is to look forward, identifying new opportunities and facing new challenges in online and digital learning. But he’s also a professor of American history. In that capacity, his job also requires him to study the opportunities and challenges people faced in the past—and, in the classroom, to make those past events meaning
What’s Worth Making? with Prof. Hal Abelson
Professor Hal Abelson has been active in computer science for over half a century—the first computer he worked with, in high school, was the kind where programs were encoded in a pattern of holes punched into a paper tape fed into the machine. When he arrived at MIT as a graduate student in the late 1960s, Abelson became involved in exploring computers’ potential as educational tools. One of his f
Everything Here Is Sacred (Terrascope Radio Replay)
In a departure from our usual format, in which we interview an exceptional faculty member to learn about their approach to teaching, this time we’re showcasing an exemplary piece of student work: an exploration of ways in which seemingly everyday places and activities, such as a cornfield, the meeting place of two rivers, or the process of planting and tending crops, are imbued with sacredness in
The Power of Experience with Dr. Ari Epstein
You thought Chalk Radio was a podcast about inspired teaching at MIT? Yes and no! “We don't do a lot of teaching,” says Dr. Ari Epstein, our guest for this week’s episode. Dr. Epstein is associate director of the Terrascope program, a learning community for first-year undergraduates. Each year the program focuses on one particular issue relating to sustainability, and participants in the program l
Economics and Real-World Impact with Dr. Sara Ellison and Prof. Esther Duflo
In this episode we meet professor and Nobel laureate Esther Duflo and her colleague Dr. Sara Ellison for a discussion about economics: what it is, how it differs from sociology, how it incorporates classic intellectual tools like probability and statistics with newer technologies like machine learning, and how it can itself be a tool for improving the world by solving problems of inequity one prob
The Lumpy Universe with Prof. David Kaiser
This conversation with Prof. David Kaiser, who teaches physics and the history of science at MIT, covers a vast timespan, from the beginning of the universe to the present day. Prof. Kaiser explains that inflationary cosmology helps connect our understanding of quantum fluctuations—what he calls the “jitters” that particles undergo at subatomic levels—to the irregular distribution of matter in the
Reimagining Cities with Prof. David Hsu
Paradoxically, urban planning professor David Hsu doesn’t consider himself a “city person,” but he has great appreciation and enthusiasm for cities as places where meaningful steps can be taken toward climate mitigation. In this episode, Prof. Hsu explains that urban planners can help move cities to take action to reduce the amount of greenhouse gas emissions from the construction, heating, power,
The Kitchen Cloud Chamber with Prof. Anne White
You don’t need a multibillion-dollar supercollider to detect subatomic particles. In fact, you can build a working cloud chamber—a device capable of revealing the cosmic radiation and radon decay events that go on continuously around us—with just a block of dry ice, some rubbing alcohol, and a few objects you probably already have in your kitchen. What’s more, constructing the cloud chamber only t
Honoring Your Native Language with Prof. Michel DeGraff
We first interviewed Professor Michel DeGraff back in season 1; he now returns for another episode, diving deeper into issues of culture and identity. He talks about his childhood in Haiti, where he was punished at school for speaking his own mother tongue, and where he was taught by his teachers and even his parents that Kreyòl was not “a real language.” After doing early work in natural language
Sustainability Education Across Learning Environments with Dr. Liz Potter-Nelson and Sarah Meyers
Many people associate the word “sustainability” with a few specific activities such as composting or recycling. Our guests for this episode, Dr. Liz Potter-Nelson and Sarah Meyers, point out that sustainability is actually much broader, encompassing all the future-oriented practices that promote the continued flourishing of individuals, cultures, and life on earth. Dr. Potter-Nelson and Meyers hav
Teaching Teachers with Dr. Summer Morrill
Nobody comes into this world already knowing how to teach—and most students arrive at undergraduate or graduate programs without any teaching experience at all. For those who are selected to be teaching assistants, the prospect of facing a classroom of students for the first time can be terrifying. To assuage those fears and provide pedagogical skills, the Biology department at MIT runs a training
Communication is the Whole Game with Paige Bright & Prof. Haynes Miller
In this episode we meet Haynes Miller, Professor Emeritus of Mathematics, who in his 35+ years of active teaching at MIT has done much to shape the institute’s math curriculum. Prof. Miller’s special focus is algebraic topology, but his teaching has encompassed a wide range of other topics from differential equations to number theory, and he has a special interest in teaching undergraduates. Join
Opening Computer Science to Everyone with Chancellor Eric Grimson
Eric Grimson is MIT’s chancellor for academic advancement and interim vice president for Open Learning; he’s also a longstanding professor of computer science and medical engineering. In this episode, Prof. Grimson shares his thoughts on in-person and online education. We learn that he rehearses each lecture one, two, or even three times before coming to the classroom, and that he often pauses in
Seeing Green with Drs. Sandland and Chazot
MIT has long been an innovator in online education. For even longer—for its whole history, in fact—it has championed hands-on learning. These two emphases may seem incompatible, but the MICRO initiative draws on both in an effort to increase diversity within the field of materials science. Dr. Jessica Sandland and Dr. Cécile Chazot, our guests for this episode, describe how MICRO recruits undergra
Well-being is the Goal with Prof. Frank Schilbach
Do you always make the best possible choices, even when you’re stressed or short on sleep? The ideally rational person (“Homo economicus”) assumed by conventional economics always acts in ways that are materially advantageous to them. But Associate Professor Frank Schilbach seeks in his research and teaching to explore the ways in which Homo economicus fails as a model of actual human behavior; in
The Greatest Existential Threat with Prof. Robert Redwine and Dr. Jim Walsh
To most people, especially those who are too young to remember the Cold War, the possibility of nuclear Armageddon may seem so remote as not to be worth contemplating. But Prof. Bob Redwine and Jim Walsh, two of the instructors behind MIT’s Nuclear Weapons Education Project (NWEP), warn that it may not be so unlikely after all, and that failure to take the threat of nuclear war seriously makes it
Visualizing Calculus with Professor Gigliola Staffilani
Professor Gigliola Staffilani, who teaches in MIT’s Department of Mathematics, was closely involved in designing and teaching the introductory-level 18.01 Calculus I course series now found on the MIT Open Learning Library. She’s also been involved in teaching calculus to students on campus. To help students become proficient in a notoriously intimidating subject, she has tried to design learning
Finding Expertise Everywhere with Prof. M. Amah Edoh
Though there’s widespread consensus that the slavery and colonization that characterize the history of European relations with Africa represent a legacy of grave injustice, there is much less agreement on how to redress that injustice. Professor M. Amah Edoh, who teaches in MIT’s Department of Anthropology, designed the course 21A.S01 Reparations for Slavery and Colonization with the goal of hones
AI Literacy for All with Prof. Cynthia Breazeal
When humans interact, they don’t just pass information from one to the other; there’s always some relational element, with the participants responding to each other’s emotional cues. Professor Cynthia Breazeal, MIT’s new Dean of Digital Learning, believes it’s possible to design this element into human-computer interactions as well. She foresees a day when AI won’t merely perform practical tasks f
Making Ethical Decisions in Software Design with Prof. Daniel Jackson & Serena Booth
In the previous episode we learned about a project undertaken as part of the Social and Ethical Responsibilities of Computing (SERC) initiative at MIT’s Schwartzman College of Computing. In this episode we hear about another SERC project, from Prof. Daniel Jackson and graduate teaching assistant Serena Booth, who have partnered to incorporate ethical considerations in Prof. Jackson and Prof. Arvin
The Human Element in Machine Learning with Prof. Catherine D’Ignazio, Prof. Jacob Andreas & Harini Suresh
When computer science was in its infancy, programmers quickly realized that though computers are astonishingly powerful tools, the results they achieve are only as good as the data you feed into them. (This principle was quickly formalized as GIGO: “Garbage In, Garbage Out.”) What was true in the era of the UNIVAC has proved still to be true in the era of machine learning: among other well-publici
When There Isn't A Simple Answer with Prof. Dennis McLaughlin
Most of the students in Professor Dennis McLaughlin’s course 1.74 Land, Water, Food, and Climate come to it with established opinions on some very controversial topics: whether GMOs are safe, whether climate change is real (and really human-induced), whether organic agriculture is preferable to conventional agriculture, and whether it’s better for land to be worked by individual farmers or by larg
Learning about Life through Laboratory Chemistry with Drs. John Dolhun & Sarah Hewett
Students in MIT’s course 5.310 Laboratory Chemistry have a state-of-the art lab to work in, with energy-saving hibernating fume hoods and a new spectrometer that achieves mind-blowingly precise measurements—not parts per million or parts per billion, but parts per trillion! And the students do spend much of their time in that new lab. But Dr. John Dolhun, director of the Undergraduate Chemistry Te
Re-engineering Education with VP for Open Learning Sanjay Sarma
Sanjay Sarma is not only a professor of mechanical engineering; he’s also Vice President for Open Learning at MIT, where he oversees innovative efforts to reimagine education, and he is coauthor (with Luke Yoquinto) of the recent book Grasp, which explores the nature of learning. In this episode, Professor Sarma discusses the differences between nominal learning, in which you memorize a fact or pr
Sketching a Picture of the Mind with Prof. Nancy Kanwisher
Nancy Kanwisher, founding member of the McGovern Institute for Brain Research and professor in MIT’s Department of Brain and Cognitive Sciences, describes the effort to understand the mind as “the grandest scientific quest of all time,” partly because it seeks to answer fundamental questions that all people ponder from time to time: What is knowledge? How does memory work? How do we form our perce

Visualizing the Future of Spaceship Earth (Prof. Dava Newman)
Professor Dava Newman is an aerospace engineer whose career has largely focused on developing improved space suits for eventual interplanetary travel. But in recent years she has turned her sights back toward Earth, using the vast amounts of data collected by satellites in near space to inform and motivate the public for the fight against catastrophic climate change. In this episode, Prof. Newman
Encountering Each Other (Essayist Garnette Cadogan)
Garnette Cadogan is an acclaimed essayist who teaches in MIT’s Urban Studies and Planning program. As befits a teacher who is also a professional creative writer, he conceives of the academic syllabus as a matrix of interconnected and recurring themes and leitmotifs, not as a schematic outline of self-contained units. In this episode, he describes how he designed his latest class, 11.S947 The Fire
Seeing the Big Picture from Space (Astronaut Jeff Hoffman)
Over the years, Sarah Hansen has interviewed the creator of the “Women of NASA” minifigure series as well as a professor of astronautics and former deputy administrator of NASA. Now, for the first time, she interviews an actual astronaut, Jeff Hoffman, who teaches aerospace engineering and systems engineering at MIT. In this episode, Prof. Hoffman describes his experiences in space and how one’s u
Making Solid State Chemistry Matter (Prof. Jeffrey Grossman)
First-year students who already plan to major in chemistry don’t require any special bells or whistles to motivate them to study the subject. But introductory chemistry is a required subject for all students at MIT, regardless of their intended major, and materials scientist Jeffrey Grossman has found that for many students in his course 3.091 Introduction to Solid State Chemistry, the subject bec
Searching for the Oldest Stars (Prof. Anna Frebel)
For millions of years after the Big Bang, nearly all the matter in the universe was in the form of hydrogen and helium; other elements like carbon, nitrogen, and oxygen only formed later, in nuclear reactions inside stars. To learn what the universe looked like back then, MIT astrophysicist Anna Frebel studies the oldest stars we can find—13 billion years old, to be precise—scanning them for trace
Paying it Forward with FinTech (Prof. Gary Gensler)
One might imagine that an expert on financial technology would view human relations through a primarily transactional lens. But Professor Gary Gensler, in teaching his course on financial technology (or “FinTech”) at MIT’s Sloan School of Management, tries to base his interactions with his students on a different model. Feeling indebted to the older mentors who helped and supported him in his stud
The Power of OER with Profs. Mary Rowe and Elizabeth Siler
Many instructors in recent years have turned to open educational resources (OER) so that their students don’t have to pay for an expensive textbook. And that is indeed one of the foremost benefits of OER. But Professor Elizabeth Siler, who teaches at Worcester State University, has found that using OER offers advantages to instructors too: doing so allows you to teach the material you think your s
Thinking Like an Economist with Prof. Jonathan Gruber
Professor Jonathan Gruber wants to train students to think like economists. Economics uses elegant mathematical models to explain how people make decisions and allocate their resources—but all too often those models are taught in ways that remain disconnected from students’ own experience. In this episode, Professor Gruber shares his thoughts on bridging that gap in his course 14.01 Introductory M
Learning to Fly with Drs. Philip Greenspun & Tina Srivastava
Can you really learn to fly by sitting in a classroom and attending lectures? Of course not! But the course offered by Philip Greenspun and Tina Srivastava in 16.687 Private Pilot Ground School has proven surprisingly popular as a means of learning the basic principles one needs to know before getting into the cockpit of a small aircraft. Originally offered in weekly class sessions over the course
Unpacking Misconceptions about Language & Identities with Prof. Michel DeGraff
“We all hold dear certain attitudes about language,” Professor Michel DeGraff says in this episode centered on his course 24.908 Creole Languages and Caribbean Identities. Those attitudes can be positive for ourselves and for others, DeGraff says, but they can also have negative effects. His goal is to make linguistics accessible to a broader audience, to connect language to issues of culture and
Special Episode: Teaching Remotely During Covid-19 with Prof. Justin Reich
Join us as we talk with Justin Reich, assistant professor in comparative media studies at MIT. Professor Reich runs the Teaching Systems Lab, which was founded with the mission of designing, implementing, and researching the future of teacher learning. With the emergence of the current coronavirus pandemic, Prof. Reich has been turning his attention to helping teachers and education policy makers
Hands-on, Minds On with Dr. Christopher Terman
You might imagine that fluency is an inherently good thing in teaching. But Dr. Christopher Terman, Senior Lecturer Emeritus at MIT’s Computer Science & Artificial Intelligence Lab, explains that breaks in the flow of the classroom can actually make the learning experience more memorable. This is just one of the insights Dr. Terman has gained in twenty years of teaching the course 6.004 Computatio
Film Is for Everyone with Prof. David Thorburn
What would Shakespeare have made of today’s popular television shows? He might or might not like them, but he wouldn’t dismiss them simply because they’re popular. In this episode, Professor David Thorburn, who has spent his career challenging conventional assumptions about what kinds of works have artistic merit, speaks eloquently about why popular art forms like film and television belong in the
Social Impact at Scale, One Project at a Time with Dr. Anjali Sastry
This episode explores a new kind of independent study. MIT has traditionally encouraged its Sloan MBA fellows to engage in international projects with partners around the globe. Our guest, Dr. Anjali Sastry, has led over 100 groups of MBA fellows in these projects. But she recently changed the structure of the class so that instead of signing on to projects developed by instructors, students are n
Making Deep Learning Human with Prof. Gilbert Strang
Mathematics Professor Gilbert Strang is one of MIT’s most revered instructors; his courses, especially the perennially popular linear algebra course 18.06, have received millions of visits on OpenCourseWare, and his lecture videos have won him a devoted following on YouTube as well. (A sample YouTube comment on one of his lectures: “This is not lecture, this is art.”) A few years ago, Professor St
How Africa Has Been Made to Mean with Prof. Amah Edoh
“How has Africa been made to mean?” For a long time, Africa has been depicted in the arts and media as a place of famine and dysfunction. More recently, the continent has been increasingly portrayed as the next frontier for business and artistic innovation. In this episode, we talk with MIT Professor of African Studies M. Amah Edoh about how Africa, as a concept, is produced through cultural pract
Nuclear Gets Personal with Prof. Michael Short
It’s a safe bet that Professor Michael Short’s 22.01 Introduction to Nuclear Engineering and Ionizing Radiation is the only course at MIT where students are encouraged to bring their toenail clippings to class. In this episode, Professor Short discusses one of the core principles of his teaching philosophy: the importance of making abstract concepts tangible by means of hands-on activities. Want t
