History

Prof. Joshua Bennett speaks with NPR host Michel Martin about his new book “The People Can Fly: American Promise, Black Prodigies, and the Greatest Miracle of All Time.” The book “weaves together folklore, history and memoir to sort through what it means to be a prodigy, especially a Black prodigy,” explains Martin. Bennett cites fatherhood and his mother’s ideals as his inspiration for the book: “In becoming a father who's raising my children in a very different context in suburban Massachusetts and not in the Bronx and in South Yonkers and having very different experiences than my parents did… I just started to think, what's the full breadth of what I've inherited around this idea of what it means to pursue an education? And that's really what inspired it.” 

Prof. Karilyn Crockett speaks with Boston Globe reporters Niki Griswold and Janelle Nanos about the city of Boston’s plans for economic development. “This is a moment to continue this focus and commitment and double down on it.” 

While studying a 2,000-year-old construction site in Pompeii, MIT researchers uncovered new insights into the Roman building process, including the key ingredients needed to develop long-standing durable Roman concrete, reports Luis Prada for Vice. “Ancient Roman builders were ‘hot-mixing,’ which means that they dumped volcanic ash and powdered quicklime together dry, then added water later, triggering a chemical reaction that cooked the mixture from the inside,” writes Prada. 

A new paper by Prof. Admir Masic and his colleagues details their new findings on the specific ingredients used by ancient Romans to develop durable concrete, reports Sarah Kuta for Smithsonian Magazine. “Looking ahead, the findings could help improve modern construction techniques, informing the development of next-generation durable, low-carbon concrete,” writes Kuta. 

A new paper by Prof. Admir Masic and his colleagues reinforces his theory that the ancient Romans used a technique called “hot-mixing” to create concrete, reports Andrew Paul for Popular Science. “The evidence resides at an ancient Roman construction site preserved in great detail by the Mount Vesuvius eruption,” explains Paul. “Isotopic analysis confirmed that the workers in Pompeii relied on hot-mixing when making their concrete.” 

By studying a workshop that was buried in Pompeii almost 2,000 years ago, Prof. Admir Masic and his colleagues have uncovered how the ancient Romans created self-healing and long-lasting concrete, reports James Woodford for New Scientist. Masic and his team were stunned at how “exceptionally well preserved” the site was and that it offered an opportunity to understand Roman concreting methods in a way that “no laboratory reconstruction could ever replicate”. He adds: “The materials were exactly as they were at the moment the eruption froze the city in time,”

While visiting a house that was under renovation when Mount Vesuvius erupted, MIT researchers were able to confirm the tools and ingredients used by ancient Romans to create long-lasting concrete, reports Humberto Basilio for Scientific American. “The hot mixing method creates fragmented, highly porous lime clasts within the mortar that allow calcium to easily travel through the material and recrystallize to fill cracks,” Basilio explains. “Understanding and mastering this “self-healing” technology will allow engineers to use the technique in modern construction.” 

Prof. Admir Masic and his colleagues have confirmed that ancient Romans utilized “hot-mixing,” a technique that combines quicklime with volcanic rock, volcanic ash, and water, to create concrete that has lasted for thousands of years, reports Margherita Bassi for Gizmodo. “The team also discovered weights and measurement tools, which they propose may have been used to maintain concrete pouring ratios and build straight, even walls,” writes Bassi. “In short, the site revealed the clearest evidence yet of the ancient Roman use of hot-mixing in concrete.” 

While analyzing samples from a newly-discovered construction site in Pompeii, researchers at MIT confirmed the ingredients and methods behind the ancient Romans’ durable and self-healing concrete, reports Will Dunham for Reuters. "Modern concretes generally lack intrinsic self-healing capability, which is increasingly important as we seek longer-lasting, lower-maintenance infrastructure," explains Prof. Admir Masic. "While the ancient process itself is not a direct replacement for modern standards, the principles revealed can inform the design of next-generation durable, low-carbon concretes."

Wall Street Journal reporter Angelina Torre spotlights “Letterlocking: The Hidden History of the Letter,” a new book by MIT Libraries Conservator Jana Dambrogio and King’s College London Senior Lecturer Daniel Smith that explores the history and art of “folding a letter so it serves as its own envelope.” The book “calls on scholars to ‘read the folds’ of written correspondence – to peer into the historical, social or personal circumstances that might not be explicitly stated,” explains Torre. 

Writing for The Boston Globe, Prof. Karilyn Crockett explores the history of the Home for Aged Colored Women and its residents, noting that “uncovering the stories of these women, many of whom worked for decades as domestic servants for wealthy Boston families, has been a revelation." Crockett explains that: “using US Census records, Ancestry.com, and materials from the Massachusetts Historical Society and National Park Service, students painstakingly sifted through newspapers, birth certificates, and cursive-laden archival records to bring these women to life.” 

Smithsonian Magazine reporter Michael Snyder spotlights Marion Mahony Griffin,  an “inventive and remarkable architect” who was the second woman to earn an architecture degree from MIT. “A brilliant graphic artist with a deep interest in Japanese printmaking, Mahony created the signature aesthetic of [Frank Llyod] Wright’s perspective drawings, bursting with exquisite detail,” explains Snyder. 

Prof. Admir Masic speaks with New York Times reporter Amos Zeeberg about his research studying the benefits of lime clasts – a material used in ancient Roman infrastructure. According to Masic’s research, “these lime clasts were actually reservoirs of calcium that helped fill in cracks, making the concrete self-healing,” writes Zeeberg. “As cracks formed, water would seep in and dissolve the calcium in the lime, which then formed solid calcium carbonate, essentially creating new rock that filled in the crack.”

Graduate student Krista Mileva-Frank is curating “Objects for a Heavenly Cave,” an art exhibition at the Marta gallery in Los Angeles, highlighting the work of 13 artists and collectives considering “how the legacy of the Renaissance grotto might extend to their own work,” reports Laura Bannister for The New York Times. “Mileva-Frank hopes the show will encourage audiences to consider the relationship between art and nature and to contend with their own limited agency in an era of climate disaster,” writes Bannister. 

STAT lists “The Exceptions: Sixteen Women, MIT, and the Fight for Equality in Science,” by Kate Zernicke as a “best book on health and science to check out this summer.”  The book focuses on Prof. Nancy Hopkins’ “career, which culminates in not only numerous scientific successes but also a collaborative effort with 15 other women faculty demonstrating evidence of gender discrimination at MIT,” explains STAT. “This work led to studies to address gender equity at nine other universities.”
