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 she doesn’t see her photographic work as a form of self-expression. Instead, the subtle decisions she makes in setting up a composition, taking the photo, cropping it, and so on, are all in the service of creating an image that will communicate vital facts about the phenomenon she’s capturing. That doesn’t mean she doesn’t also want her images to be visually gripping and aesthetically appealing, but for her, the science always comes first, and any manipulations that obscure the truth are unacceptable. In this episode, Frankel talks with host Sarah Hansen about stumbling into a career as a science photographer, about sparring with researchers over photographic design decisions, and about what happened when she attempted to use AI to duplicate one of her images.

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 United States and worldwide. In this episode, we hear from senior manager of MIT Open Education collaborations, Dr. Shira Segal, who talks about MIT’s efforts to team up with and learn from open education practitioners at the Maricopa County Community College District in Arizona, whose energetic promotion of open educational resources has saved students over $270 million in textbook costs, and College of the Canyons in California, a leader in the Zero Textbook Cost movement. We also hear excerpts from interviews with four instructors from those colleges, who talk about the potential benefits and unexpected challenges of using open educational resources in general, and about what they learned from their experiences in adapting OCW materials for use in their own classes.Relevant Resources:MIT OpenCourseWareThe OCW Educator PortalMore on MIT OpenCourseWare’s collaboration with community collegesMaricopa County Community College DistrictCollege of the CanyonsMaricopa Community Colleges Save Students $270M in TextbooksOER and Zero Textbook Cost at College of the CanyonsMusic in this episode by Blue Dot Sessions Connect with UsIf you have a suggestion for a new episode or have used OCW to change your life or those of others, tell us your story.

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 and demand—do a better job of deciding how to allocate resources than can be achieved by a top-down, command-economy approach. But as Gruber goes on to explain, that principle only holds when all participants have equal access to markets and to information; in the real world, imbalances in that access lead to market failures, inefficient allocations of resources that leave most people worse off than they would otherwise be. That’s why government regulation still has a role in a properly functioning economy. Tune in to hear Prof. Gruber explain why we need “capitalism with gutter guards” to ensure equitable outcomes, especially in sectors of the economy such as healthcare where the ideal markets envisioned by classical economics are particularly unattainable or undesirable. Relevant Resources:MIT OpenCourseWareThe OCW Educator portalProf. Gruber’s faculty page14.01 Principles of Microeconomics on MIT OpenCourseWare14.41 Public Finance and Public Policy on MIT OpenCourseWarePower and Progress (book by Daron Acemoglu and Simon Johnson)Video version of this interview on YouTubeMusic in this episode by Blue Dot Sessions Connect with UsIf you have a suggestion for a new episode or have used OCW to change your life or those of others, tell us your story.

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 advisor is useful–someone who understands the concepts, can crunch the numbers, and has a fiduciary responsibility to look out for your best interests. For many people, hiring a financial advisor might be a financial impossibility, but Prof. Lo and his colleagues are working to develop an AI financial advisor that not only gives ordinary people access to sound financial advice, but acts with real fiduciary responsibility. Large language models can’t do this yet, he says, but the technology is developing fast. Other topics he touches on in this episode include the outsized influence of finance on drug development and global decarbonization and the equally outsized influence of teachers on their students–he names many who changed his own life, from his third-grade teacher in Queens to his professors at college and graduate school.        Relevant Resources:MIT OpenCourseWareThe OCW Educator portalProfessor Lo’s faculty page15.401 Finance Theory I on MIT OpenCourseWare15.481x Adaptive Markets: Financial Market Dynamics and Human Behavior on MIT Open Learning Library15.482x Healthcare Finance on MIT Open Learning LibraryVideo version of this interview on YouTubeMusic in this episode by Blue Dot Sessions  Connect with UsIf you have a suggestion for a new episode or have used OCW to change your life or those of others, tell us your story.

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 Talent certificate program in Computer and Data Science and is pursuing a MicroMasters in statistics and data science through the support of MIT Emerging Talent. In this episode, we hear how Sujood and her classmates at the university in Khartoum used MIT OpenCourseWare lecture videos as the basis of a group learning experience, in which knowledge was shared and lasting friendships were formed. We also hear how Sujood is pursuing her current online studies not just as a means of self-improvement but as part of the groundwork for a much bigger, future project: helping to rebuild Sudan’s educational and scientific infrastructure when peace comes to that country. “I'm not doing it just for myself,” she says. “I'm not doing it just for my family, but in the bigger picture and with a heart filled with hope.”The Open Learners podcast is produced by Alexis Haut and hosted by Emmanuel Kasigazi and Michael Jordan Pilgreen.Relevant Resources:MIT OpenCourseWareThe OCW Educator portalMIT Emerging Talent programMIT MicroMasters Program in Statistics and Data ScienceMusic in this episode by Blue Dot Sessions Share Your Open Learning StoryTo share your own open learning story with Michael and Emmanuel, send them an email at open_learners_pod@mit.edu.

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 OpenCourseWare and had seen what it had to offer; now he returned to MIT Open Learning resources in earnest, plowing through courses in data science and computer programming; soon thereafter he was accepted into the MIT Emerging Talent certificate program, where he began to develop an interest in entrepreneurship. Now, just a few years later, Jerry has his own startup, Everpesa Technologies, a financial services platform that offers sustainable investment opportunities and financial literacy resources to people in sub-Saharan Africa. Along the way, he has become a self-described “OCW ambassador,” enthusiastically spreading the word to relatives and colleagues about the learning resources that are available online through MIT OpenCourseWare. “You don’t need to pay anything,” Jerry tells them. “You just need to have a bit of time.”The Open Learners podcast is produced by Alexis Haut and hosted by Emmanuel Kasigazi and Michael Jordan Pilgreen.Relevant Resources:MIT OpenCourseWareThe OCW Educator portalMIT Emerging Talent programMIT Jameel World Education LabMIT MicroMasters Program in Statistics and Data ScienceEverpesa website6.0001 Introduction to Computer Science and Programming in Python on MIT OpenCourseWareMusic in this episode by Blue Dot Sessions Share Your Open Learning StoryTo share your own open learning story with Michael and Emmanuel, send them an email at open_learners_pod@mit.edu.

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 electrical engineering at the university. Even there, though, the internet infrastructure was shaky enough that Lotfullah often resorted to downloading the course materials so he could study them at leisure when broadband wasn’t available. He now resides in India and recently graduated from the MIT Emerging Talent certificate program in Computer and Data Science, specifically designed for displaced communities worldwide. As he continues his educational journey in data science and artificial intelligence, he remains deeply mindful of the challenges he encountered as a student in his home country. Recognizing that most of the available online educational resources are in English, a language few Afghans are fluent in, Lotfullah has used his computer skills to create an online learning platform offering educational materials in Persian. Someday, he hopes the platform will expand to include full online courses with direct interaction between instructors and students.The Open Learners podcast is produced by Alexis Haut and hosted by Emmanuel Kasigazi and Michael Jordan Pilgreen. Relevant Resources:MIT OpenCourseWareThe OCW Educator portalMIT Emerging Talent programMIT MicroMasters Program in Statistics and Data Science6.0001 Introduction to Computer Science and Programming in Python on MIT OpenCourseWareHooshmand Lab online learning website (in Persian)Music in this episode by Blue Dot Sessions Share Your Open Learning StoryTo share your own open learning story with Michael and Emmanuel, send them an email at open_learners_pod@mit.edu.

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 discovered the world of educational resources that MIT Open Learning offers. He devoured MIT OpenCourseWare courses in statistics, computer programming, and calculus, and soon realized that he could take steps toward a career in finance by enrolling in a MITx MicroMasters program. The program’s instructional team recognized Nader’s talent, and when he finished the program they offered him a position as a teaching assistant. From there, drawing on the skills he had learned but also on the online community he had become a part of, Nader was able to get jobs in his field, first working for a financial firm in Jordan, and then for companies in the US and Dubai. In this episode, we hear his inspiring story of passion and perseverance.The Open Learners podcast is produced by Alexis Haut and hosted by Emmanuel Kasigazi and Michael Jordan Pilgreen. Relevant Resources:MIT OpenCourseWareThe OCW Educator portalMIT MicroMasters Program in FinanceDr. Egor Matveyev (MIT faculty page)Prof. Andrew Lo (MIT faculty page)Courses by Prof. Lo on MIT OpenCourseWareMusic in this episode by Blue Dot Sessions Share Your Open Learning StoryTo share your own open learning story with Michael and Emmanuel, send them an email at open_learners_pod@mit.edu.

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. Aiming to widen her cultural horizons, she opted to attend high school in New Zealand; a few years later, she transferred from a Korean university to an American one so she could attend in-person classes during the Covid pandemic. With the help of lecture videos from MIT OpenCourseWare, Jae-Min was able to supplement her formal studies and pursue all the subjects that interest her, from chemistry and thermodynamics through data science and financial technology. She’s now back in South Korea, where she’s finishing a degree in economics at Yonsei University. She feels it’s time for her to really focus her attention on a single field and a single goal, a career in investment banking. But if that doesn’t work out, she says, she can always come back to MIT OpenCourseWare and dip once more into the wealth of resources it has to offer.  The Open Learners podcast is produced by Alexis Haut.Relevant Resources:MIT OpenCourseWareThe OCW Educator portal5.60 Thermodynamics & Kinetics on MIT OpenCourseWare15.401 Finance Theory I on MIT OpenCourseWare18.06 Linear Algebra on MIT OpenCourseWareProf. Gilbert Strang (MIT faculty page)RES.18-005 Highlights of Calculus (including “The Big Picture of Calculus”) on MIT OpenCourseWareMusic in this episode by Blue Dot Sessions Share Your Open Learning StoryTo share your own open learning story with Michael and Emmanuel, send them an email at open_learners_pod@mit.edu.
