    MIT OpenCourseWare is “a living testament to the nobility of open, unbounded learning”

    by

    Mostafa Fawzy became interested in physics in high school. It was the “elegance and paradox” of quantum theory that got his attention and led to his studies at the undergraduate and graduate level. But even with a solid foundation of coursework and supportive mentors, Fawzy wanted more. MIT Open Learning’s OpenCourseWare was just the thing he was looking for.  Now a doctoral candidate in atomic physics at Alexandria University and an assistant lecturer of physics at Alamein International University in Egypt, Fawzy reflects on how MIT OpenCourseWare bolstered his learning early in his graduate studies in 2019.  Part of MIT Open Learning, OpenCourseWare offers free, online, open educational resources from more than 2,500 courses that span the MIT undergraduate and graduate curriculum. Fawzy was looking for advanced resources to supplement his research in quantum mechanics and theoretical physics, and he was immediately struck by the quality, accessibility, and breadth of MIT’s resources. “OpenCourseWare was transformative in deepening my understanding of advanced physics,” Fawzy says. “I found the structured lectures and assignments in quantum physics particularly valuable. They enhanced both my theoretical insight and practical problem-solving skills — skills I later applied in research on atomic systems influenced by magnetic fields and plasma environments.”  He completed educational resources including Quantum Physics I and Quantum Physics II, calling them “dense and mathematically sophisticated.” He met the challenge by engaging with the content in different ways: first, by simply listening to lectures, then by taking detailed notes, and finally by working though problem sets. Although initially he struggled to keep up, this methodical approach paid off, he says. He is grateful to his undergraduate mentors, professors M. Sakr and T. Bahy of Alexandria University, as well as to MIT OpenCourseWare, calling it a “steadfast companion through countless solitary nights of study, a beacon in times when formal resources were scarce, and a living testament to the nobility of open, unbounded learning.”  Recognizing the power of mentorship and teaching, Fawzy serves as an academic mentor with the African Academy of Sciences, supporting early-career researchers across the continent in theoretical and atomic physics.  “Many of these mentees lack access to advanced academic resources,” he explains. “I regularly incorporate OpenCourseWare into our mentorship sessions, using it as a foundational teaching and reference tool. It’s an equalizer, providing the same high-caliber content to students regardless of geographical or institutional limitations.” As he looks toward the future, Fawzy has big plans, influenced by MIT. “I aspire to establish a regional center for excellence in atomic and plasma physics, blending cutting-edge research with open-access education in the Global South,” he says. As he continues his research and teaching, he also hopes to influence science policy and contribute to international partnerships that shine the spotlight on research and science in emerging nations.  Along the way, he says, “OpenCourseWare remains a cornerstone resource that I will return to again and again.”  Fawzy says he’s also interested in MIT Open Learning resources in computational physics and energy and sustainability. He’s following MIT’s Energy Initiative, calling it increasingly relevant to his current work and future plans.  Fawzy is a proponent of open learning and a testament to its power. “The intellectual seeds sown by Open Learning resources such as MIT OpenCourseWare have flourished within me, shaping my identity as a physicist and affirming my deep belief in the transformative power of knowledge shared freely, without barriers,” he says.  More

      in Energy

      On batteries, teaching, and world peace

      by

      Over his long career as an electrochemist and professor, Donald Sadoway has earned an impressive variety of honors, from being named one of Time magazine’s 100 most influential people in 2012 to appearing on “The Colbert Report,” where he talked about “renewable energy and world peace,” according to Comedy Central.

      What does he personally consider to be his top achievements?

      “That’s easy,” he says immediately. “For teaching, it’s 3.091,” the MIT course on solid-state chemistry he led for some 18 years. An MIT core requirement, 3.091 is also one of the largest classes at the Institute. In 2003 it was the largest, with 630 students. Sadoway, who retires this year after 45 years in the Department of Materials Science and Engineering, estimates that over the years he’s taught the course to some 10,000 undergraduates.

      A passion for teaching

      Along the way he turned the class into an MIT favorite, complete with music, art, and literature. “I brought in all that enrichment because I knew that 95 percent of the students in that room weren’t going to major in anything chemical and this might be the last class they’d take in the subject. But it’s a requirement. So they’re 18 years old, they’re very smart, and many of them are very bored. You have to find a hook [to reach them]. And I did.”

      In 1995, Sadoway was named a Margaret MacVicar Faculty Fellow, an honor that recognizes outstanding classroom teaching at the Institute. Among the communications in support of his nomination:

      “His contributions are enormous and the class is in rapt attention from beginning to end. His lectures are highly articulate yet animated and he has uncommon grace and style. I was awed by his ability to introduce playful and creative elements into a core lecture…”

      Bill Gates would agree. In the early 2000s Sadoway’s lectures were shared with the world through OpenCourseWare, the web-based publication of MIT course materials. Gates was so inspired by the lectures that he asked to meet with Sadoway to learn more about his research. (Sadoway initially ignored Gates’ email because he thought his account had been hacked by MIT pranksters.)

      Research breakthroughs

      Teaching is not Sadoway’s only passion. He’s also proud of his accomplishments in electrochemistry. The discipline that involves electron transfer reactions is key to everything from batteries to the primary extraction of metals like aluminum and magnesium. “It’s quite wide-ranging,” says the John F. Elliott Professor Emeritus of Materials Chemistry.

      Sadoway’s contributions include two battery breakthroughs. First came the liquid metal battery, which could enable the large-scale storage of renewable energy. “That represents a huge step forward in the transition to green energy,” said António Campinos, president of the European Patent Office, earlier this year when Sadoway won the 2022 European Inventor Award for the invention in the category for Non-European Patent Office Countries.

      On “The Colbert Report,” Sadoway alluded to that work when he told Stephen Colbert that electrochemistry is the key to world peace. Why? Because it could lead to a battery capable of storing energy from the sun when the sun doesn’t shine and otherwise make renewables an important part of the clean energy mix. And that in turn could “plummet the price of petroleum and depose dictators all over the world without one shot being fired,” he recently recalled.

      The liquid metal battery is the focus of Ambri, one of six companies based on Sadoway’s inventions. Bill Gates was the first funder of the company, which formed in 2010 and aims to install its first battery soon. That battery will store energy from a reported 500 megawatts of on-site renewable generation, the same output as a natural gas power plant.

      Then, in August of this year, Sadoway and colleagues published a paper in Nature about “one of the first new battery chemistries in 30 years,” Sadoway says. “I wanted to invent something that was better, much better,” than the expensive lithium-ion batteries used in, for example, today’s electric cars.

      That battery is the focus of Avanti, one of three Sadoway companies formed just last year. The other two are Pure Lithium, to commercialize his inventions related to that element, and Sadoway Labs. The latter, a nonprofit, is essentially “a space to try radical innovations. We’re gonna start working on wild ideas.”

      Another focus of Sadoway’s research: green steel. Steelmaking produces huge amounts of greenhouse gases. Enter Boston Metal, another Sadoway company. This one is developing a new approach to producing steel based on research begun some 25 years ago. Unlike the current technology for producing steel, the Boston Metal approach — molten oxide electrolysis — does not use the element at the root of steel’s problems: carbon. The principal byproduct of the new system? Oxygen.

      In 2012, Sadoway gave a TED talk to 2,000 people on the liquid metal battery. He believes that that talk, which has now been seen by almost 2.5 million people, led to the wider publicity of his work — and science overall — on “The Colbert Report” and elsewhere. “The moral here is that if you step out of your comfort zone, you might be surprised at what can happen,” he concludes.

      Colleagues’ reflections

      “I met Don in 2006 when I was working for the iron and steel industry in Europe on ways to reduce greenhouse gas emissions from the production of those materials,” says Antoine Allanore, professor of metallurgy, Department of Materials Science and Engineering. “He was the same Don Sadoway that you see in recordings of his lectures: very elegant, very charismatic, and passionate about the technical solutions and underlying science of the process we were all investigating; electrolysis. A few years later, when I decided to pursue an academic career, I contacted Don and became a postdoctoral associate in his lab. That ultimately led to my becoming an MIT professor. People don’t believe me, but before I came to MIT the only thing I knew about the Institute was that Noam Chomsky was there … and Don Sadoway. And I felt, that’s a great place to be. And I stayed because I saw the exceptional things that can be accomplished at MIT and Don is the perfect example of that.”

      “I had the joy of meeting Don when I first arrived on the MIT campus in 1994,” recalls Felice Frankel, research scientist in the MIT departments of Chemical Engineering and Mechanical Engineering. “I didn’t have to talk him into the idea that researchers needed to take their images and graphics more seriously.  He got it — that it wasn’t just about pretty pictures. He was an important part of our five-year National Science Foundation project — Picturing to Learn — to bring that concept into the classroom. How lucky that was for me!”

      “Don has been a friend and mentor since we met in 1995 when I was an MIT senior,” says Luis Ortiz, co-founder and chief executive officer, Avanti Battery Co. “One story that is emblematic of Don’s insistence on excellence is from when he and I met with Bill Gates about the challenges in addressing climate change and how batteries could be the linchpin in solving them. I suggested that we create our presentation in PowerPoint [Microsoft software]. Don balked. He insisted that we present using Keynote on his MacBook Air, because ‘it looks so much better.’ I was incredulous that he wanted to walk into that venue exclusively using Apple products. Of course, he won the argument, but not without my admonition that there had better not be even a blip of an issue. In the meeting room, Microsoft’s former chief technology officer asked Don if he needed anything to hook up to the screen, ‘we have all those dongles.’ Don declined, but gave me that knowing look and whispered, ‘You see, they know, too.’ I ate my crow and we had a great long conversation without any issues.”

      “I remember when I first started working with Don on the liquid metal battery project at MIT, after I had chosen it as the topic for my master’s of engineering thesis,” adds David Bradwell, co-founder and chief technology officer, Ambri. “I was a wide-eyed graduate student, sitting in his office, amongst his art deco decorations, unique furniture, and historical and stylistic infographics, and from our first meeting, I could see Don’s passion for coming up with new and creative, yet practical scientific ideas, and for working on hard problems, in service of society. Don’s approaches always appear to be unconventional — wanting to stand out in a crowd, take the path less trodden, both based on his ideas, and his sense of style. It’s been an amazing journey working with him over the past decade-and-a-half, and I remain excited to see what other new, unconventional ideas, he can bring to this world.” More

      Given what we know, how do we live now?

      by

      To truly engage the climate crisis, as so many at MIT are doing, can be daunting and draining. But it need not be lonely. Building collective insight and companionship for this undertaking is the aim of the Council on the Uncertain Human Future (CUHF), an international network launched at Clark University in 2014 and active at MIT since 2020.

      Gathering together in council circles of 8-12 people, MIT community members make space to examine — and even to transform — their questions and concerns about climate change. Through a practice of intentional conversation in small groups, the council calls participants to reflect on our human interdependence with each other and the natural world, and on where we are in both social and planetary terms. It urges exploration of how we got here and what that means, and culminates by asking: Given what we know, how do we live now?

      Origins

      CUHF developed gradually in conversations between co-founders Sarah Buie and Diana Chapman Walsh, who met when they were, respectively, the director of Clark’s Higgins School of Humanities and the president of Wellesley College. Buie asked Walsh to keynote a Ford-funded Difficult Dialogues initiative in 2006. In the years and conversations that followed, they concluded that the most difficult dialogue wasn’t happening: an honest engagement with the realities and implications of a rapidly heating planet Earth.

      With social scientist Susi Moser, they chose the practice of council, a blend of both modern and traditional dialogic forms, and began with a cohort of 12 environmental leaders willing to examine the gravest implications of climate change in a supportive setting — what Walsh calls “a kind of container for a deep dive into dark waters.” That original circle met in three long weekends over 2014 and continues today as the original CUHF Steady Council.

      Taking root at MIT

      Since then, the Council on the Uncertain Human Future has grown into an international network, with circles at universities, research centers, and other communities across the United States and in Scotland and Kathmandu. The practice took root at MIT (where Walsh is a life member emerita of the MIT Corporation) in 2020.

      Leadership and communications teams in the MIT School of Humanities, Arts and Social Sciences (SHASS) Office of the Dean and the Environmental Solutions Initiative (ESI) recognized the need the council could meet on a campus buzzing with research and initiatives aimed at improving the health of the planet. Joining forces with the council leadership, the two MIT groups collaborated to launch the program at MIT, inviting participants from across the institute, and sharing information on the MIT Climate Portal. Intentional conversations

      “The council gives the MIT community the kind of deep discourse that is so necessary to face climate change and a rapidly changing world,” says ESI director and professor of architecture John Fernández. “These conversations open an opportunity to create a new kind of breakthrough of mindsets. It’s a rare chance to pause and ask: Are we doing the things we should be doing, given MIT’s mission to the nation and the world, and given the challenges facing us?”

      As the CUHF practice spreads, agendas expand to acknowledge changing times; the group produces films and collections of readings, curates an online resource site, and convenes international Zoom events for members on a range of topics, many of which interact with climate, including racism and Covid-19. But its core activity remains the same: an intentional, probing conversation over time. There are no preconceived objectives, only a few simple guidelines: speak briefly, authentically, and spontaneously, moving around the circle; listen with attention and receptivity; observe confidentiality. “Through this process of honest speaking and listening, insight arises and trustworthy community is built,” says Buie.

      While these meetings were held in person before 2020, the full council experience pivoted to Zoom at the start of the pandemic with two-hour discussions forming an arc over a period of five weeks. Sessions begin with a call for participants to slow down and breathe, grounding themselves for the conversation. The convener offers a series of questions that elicit spontaneous responses, concerns, and observations; later, they invite visioning of new possibilities. Inviting emergent possibility

      While the process may yield tangible outcomes — for example, a curriculum initiative at Clark called A New Earth Conversation — its greatest value, according to Buie, “is the collective listening, acknowledgment, and emergent possibility it invites. Given the profound cultural misunderstandings and misalignments behind it, climate breakdown defies normative approaches to ‘problem-solving.’ The Council enables us to live into the uncertainty with more awareness, humility, curiosity, and compassion. Participants feel the change; they return to their work and lives differently, and less alone.”

      Roughly 60 faculty and staff from across MIT, all engaged in climate-related work, have participated so far in council circles. The 2021 edition of the Institute’s Climate Action Plan provides for the expansion of councils at MIT to deepen humanistic understanding of the climate crisis. The conversations are also a space for engaging with how the climate crisis is related to what the plan calls “the imperative of justice” and “the intertwined problems of equity and economic transition.”

      Reflecting on the growth of the council’s humanistic practice at MIT, Agustín Rayo, professor of philosophy and the Kenan Sahin Dean of MIT SHASS, says: “The council conversations about the future of our species and the planet are an invaluable contribution to MIT’s ‘whole-campus’ focus on the climate crisis.”

      Growing the council at MIT means broadening participation. Postdocs will join a new circle this fall, with opportunities for student involvement soon to follow. More than a third of MIT’s prior council participants have continued with monthly Steady Council meetings, which sometimes reference recent events while deepening the council practice at MIT. The session in December 2021, for example, began with reports from MIT community members who had attended the COP26 UN climate change conference in Glasgow, then broke into council circles to engage the questions raised.

      Cognitive leaps

      The MIT Steady Council is organized by Curt Newton, director of MIT OpenCourseWare and an early contributor to the online platform that became the Institute’s Climate Portal. Newton sees a productive tension between MIT’s culture of problem-solving and the council’s call for participants to slow down and question the paradigms in which they operate. “It can feel wrong, or at least unfamiliar, to put ourselves in a mode where we’re not trying to create an agenda and an action plan,” he says. “To get us to step back from that and think together about the biggest picture before we allow ourselves to be pulled into that solution mindset  — it’s a necessary experiment for places like MIT.”

      Over the past decade, Newton says, he has searched for ways to direct his energies toward environmental issues “with one foot firmly planted at MIT and one foot out in the world.” The silo-busting personal connections he’s made with colleagues through the council have empowered him “to show up with my full climate self at work.”

      Walsh finds it especially promising to see CUHF taking root at MIT, “a place of intensity, collaboration, and high ideals, where the most stunning breakthroughs occur when someone takes a step back, stops the action, changes the trajectory for a time and begins asking new questions that challenge received wisdom.” She sees council as a communal practice that encourages those cognitive leaps. “If ever there were a moment in history that cried out for a paradigm shift,” she says, “surely this is it.”

      Funding for the Council on the Uncertain Human Future comes from the Christopher Reynolds Foundation and the Kaiser Family Foundation.
