June 2021

In April 2018, Anming Hu, a Chinese-Canadian associate professor at the University of Tennessee, received an unexpected visit from the FBI. The agents wanted to know whether he’d been involved in a Chinese government “talent program,” offering overseas researchers incentives to bring their work back to Chinese universities.

Not too long ago, American universities encouraged their academics to build ties with Chinese institutions, but the US government is now suspicious of these programs, seeing them as a spy recruitment tool. Despite Hu’s denial he was

The world’s most famous concert pianos got a major tech upgrade

steinway 2 scaled

At a showroom in a Boston suburb, Patrick Elisha sat down and began to play the opening measures of Rachmaninoff’s Piano Concerto #2 to demonstrate why Steinway & Sons grand pianos are celebrated in concert halls around the world.

Steinways are meticulously crafted instruments: it takes around 250 workers a year to assemble each grand piano’s 12,000 individual parts. Everything, from the hand-bent rims (made of more than a dozen layers of rock maple, each heated and shaped to form a grand piano’s classic curves) to the small felt rollers in the piano’s action (which help dictate how much pressure it takes to play an individual note), is crafted to produce clarion, resonant tones that range from the pianissimo bell-like chimes that open the concerto to the thundering fortissimo chords that seem to rise from the depths over its next eight measures.

Elisha, who runs the education division of M. Steinert & Sons, the world’s oldest Steinway dealer, is an award-winning pianist and composer—but I wanted to hear how the piano handled a virtuoso like Lang Lang going to town on, say, “We Don’t Talk About Bruno,” Lin-Manuel Miranda’s hit from the Disney film Encanto.

STEINWAY

No problem: Elisha called up a video of Lang performing in New York’s Steinway Hall on a nearby wide-screen TV. Once he hit Play on the video, whatever Lang played was perfectly reproduced on the piano in front of me. When Lang’s right hand flew up the keyboard to produce the opening flourish in the “Bruno” video, the keys on the piano in the room where I stood were depressed with precisely the same velocity for precisely the same amount of time.

This was, I realized, the first time I had ever heard a truly lossless recording. Acoustically, I was getting the equivalent of a private concert from one of the most famous pianists alive, courtesy of Steinway’s Spirio. It’s a thoroughly modern take on the player piano—a device, popular in the early 20th century, that used rolls of paper with holes punched in them to play specific tunes, no pianist required.

Roughly half of all new Steinways sold last year included Spirio technology, which adds between $29,000 and $48,000 to what is already a $150,000 instrument. The most recent addition to the line is the Spirio | r, which has recording, editing, and playback technology. A pianist who’s learning a new piece can play it, record the effort, and then essentially watch the piano play it back—making it possible to pick up on nuances in timing and tone that might be harder to discern from an audio recording alone.

The Spirio, which launched in 2015, added an entirely new set of engineering challenges to what was already one of the most deliberately constructed instruments in history. Before it came to market, Steinway had to ensure that the Spirio tech was, as Elisha puts it, “non-parasitic.” In other words, adding pressure sensors and anything else that could cause friction between the musician and the instrument was verboten; altering the feel in any way would destroy what makes a Steinway a Steinway.

Instead, performances are recorded by dozens of gray-scale optical sensors mounted behind the keyboard that calculate the velocity at which hammers strike the piano wires whenever any of the piano’s 88 keys is pressed. (The sensors have 1,020 levels of sensitivity and can take 800 measurements per second.) A different set of sensors underneath the piano measures the pedal-guided dampers; playback of both the keys and the pedals is controlled by solenoid plungers.

Each Spirio comes with a dedicated iPad; with a couple of swipes, Spirio | r users can edit their performances in an almost infinite number of ways. Everything from individual notes to entire chords can be erased or transposed, elongated or shortened, made louder or softer—if you can imagine it, you can hear what it will sound like as it’s played back to you.

But it’s the constantly updated Spirio library, which currently includes more than 4,000 recordings and more than 100 videos, that really makes this an instrument like no

I’m a beaver. You’re a beaver. We are beavers all.

MIT beaver panorama

For more than 20 million years, beavers have been, well, busy. They’ve been felling trees for that long, and building dams and lodges for at least the last few million years, earning a well-deserved reputation for industriousness and ingenuity. It seemed only fitting, then, that MIT saw fit to claim the beaver as its mascot in 1914. By 1921, The Tech reported that gray beaver hats had become “the distinguishing mark of an Institute man” at college gatherings. The toothy, mainly nocturnal rodent has appeared on every rendition of the MIT class ring—now lovingly called the brass rat—since it was introduced in 1929. 

Read on to learn more about Castor canadensis, the remarkable four-legged engineers.

Family life

The North American beaver is the largest rodent in the Northern Hemisphere, typically weighing in at 35 to 65 pounds. (Only the South American capybara weighs more.) They make their homes in ponds, rivers, streams, and wetlands throughout most of North America.

They are one of the few species in the world that typically mate for life. Their offspring, known as kits, can swim within days of birth, but their childhoods are among the longest in the animal world. They generally live for two years with their parents, which both take part in raising them. It takes that long for the parents and older siblings to show them, by example, how to build dams and lodges, how to plan and dig channels, and how to select food, harvest it, and store it for the winter. It’s kind of like going to engineering school. Beavers then move on to form their own families, often building their own colonies. They typically live to age 10 or 12 in the wild.

well-planned diet

Beavers are vegetarians but with a twist. They favor the inner bark of certain tree species, including willow, poplar, aspen, birch, and maple, feasting on the cambium, the soft, sap-laden layer immediately under the outer bark. Conifers, however, are not considered a delicacy. Beavers eat them only rarely, and tend to fell them mainly for dam building and to encourage growth of things they’d rather eat. In summer they consume readily available grasses, leaves, herbs, fruit, and aquatic plants. To prepare for winter in cold climates, they create an underwater cache of sticks and logs they’ve gnawed from trees they’ve felled. First they assemble a floating raft of not-so-delicious branches above a deep part of their pond; then they stash their preferred branches beneath them. The pile absorbs water and sinks to the bottom, with the less-favored branches often freezing in the ice at the surface and acting as a protective covering that secures the more-desirable lower branches, which remain accessible below the ice. The cold water preserves the nutritional value of the branches.

While humans can’t digest cellulose, beavers have a small sac between the large and small intestines containing microorganisms that ferment this material, helping them digest up to 30% of it.

chieving the perfect pelt

Forget mink, ermine, and sable. Of all fur-bearing animals, beavers have the coat that is rated the warmest. So it’s no surprise that European demand for hats made of warm, water-resistant, and durable beaver felt led to lucrative trapping and fur-trading ventures in North America. In the 17th and 18th centuries, as many as 200,000 North American beaver pelts were exported annually to Europe. (Fierce competition to monopolize the fur trade led to a series of so-called Beaver Wars between 1628 and the Treaty of Montreal in 1701: the Iroquois Confederation, backed by the Dutch and British, battled the Huron Confederation, backed by France.) These enterprises gave rise to many European settlements and trading centers in North America—and nearly wiped out the continent’s beaver population.

On January 17, 1914, MIT President Richard Maclaurin accepted the Technology Club of New York’s proposal that the beaver—nature’s engineer—serve as MIT’s mascot. In 1977, TIM the beaver first showed up on campus to celebrate the 50th reunion of the Class of 1927

Divine economics

MA24 MIT Unknown jpg

Allison V. Thompkins, PhD ’11, used to spend her days steeped in statistical analysis, digging into economic data to understand how the world works. These days, you’re more likely to find her writing about how to modify prayer or meditation practices to make them more accessible for people with disabilities.

From the outside, the shift from economic policy research to a career writing and teaching about spirituality might seem like a substantial one. But for Thompkins, the instincts behind both pursuits flow from the same place.

“From my perspective, the main connecting thread of economics and spirituality is their power to improve the world,” she says.

That drive to transform the world around her into a more equitable and just place has been with Thompkins for as long as she can remember. As a kid living with cerebral palsy, she was involved in disability advocacy from a young age. At age six, she was interviewed by PBS about her love for Martin Luther King Jr. as an example of someone who fought for people’s rights, and as a nine-year-old she wrote an essay about the need for disability representation in radio programming.

As an adult, that same drive led her to MIT to study under labor economists David Autor and Joshua Angrist, both of whom are Ford professors of economics. She was one of the first people with cerebral palsy and the first power-chair user to earn a PhD from the Institute. While working on her dissertation, which focused on disability policy, she also began consulting for the World Bank. Upon graduating, she found work in economic policy at the research firm Mathematica.

When her health required that she take a step back from full-time work, she decided to share her growing spiritual practice, first on her blog and then in the form of a book, Spirituality Is for Every Body: 8 Accessible, Inclusive Ways to Connect with the Divine When Living with Disability, which was published in February.

“People are most likely more accustomed to thinking about the role of spirituality or the Divine when speaking about professions such as singing or painting or writing poetry, rather than professions that are data driven … [But] for me, the goal of practicing economics was always to improve the world,” she says. The goal of making life better for others—not just oneself—is, in her view, also “the most important reason to engage in spirituality.”

Thompkins has always looked for meaningful patterns where others might see only randomness and chance. As an economist, she takes unruly piles of numbers and transforms them into useful data that can inform things like microlending programs for people living with disabilities in India. As a spiritual seeker, she’s adopted the perspective that everything happens for a reason.

All of this has imbued her life with a deep sense of purpose, whether she’s working on disability policy or writing about meditation.

“Love and beauty—I know you don’t always hear those [words] when discussing economics,” she says with a smile on a Zoom call. “But whatever I do, I seek to allow the love and the light that I have to shine through whatever thing I choose.”

The road to economics

Thompkins’s experiences as a youth advocate set her up to dream big about what she might accomplish on behalf of the disabled community. Her hope as a teenager had been to go to law school and become a disability rights attorney—that is, until she surprised herself by falling in love with an economics course in high school. She majored in mathematical economics at Scripps College. And by the time she arrived on MIT’s campus
