Scientific American | Robo Pizzaiolo | Robot Chef Learns to Twirl Pizza Like a Pro: A New Bot Uses Feedback from Sensors to Stretch and Fold Dough
Scientific American. | Web Story. | Print Story. (June 2017: Volume 316, Issue 6) | May 16, 2017.
Pizza has a proud history of fueling late-night lab work, and scientists in Naples—an Italian city famous for its slice—have easy access to some of the world's tastiest take-out. But what inspires engineer Bruno Siciliano is not just that first bite so much as how the dish is made.
“Preparing a pizza involves an extraordinary level of agility and dexterity,” says Siciliano, who directs a robotics research group at the University of Naples Federico II. Stretching a deformable object like a lump of dough requires a precise and gentle touch. It is one of the few things humans can handle, but robots cannot—yet.
Siciliano's team has been developing a robot nimble enough to whip up a pizza pie, from kneading dough to stretching it out, adding ingredients and sliding it into the oven. RoDyMan (short for Robotic Dynamic Manipulation) is a five-year project supported by a €2.5-million grant from the European Research Council.
The Tab | Rocket Scientists Calculate the ‘Go Point’ at Princeton’s Undergraduate Women in Physics Conference
Being a woman in science isn’t easy. In most situations, you have to deal with everything that comes with being the only woman in the room. In Hidden Figures, a new film based on the true story of NASA’s female “computers”, Taraji P. Henson depicts this perfectly as legendary mathematician Katherine G. Johnson, who was awarded the Medal of Freedom in 2016 for her contributions to the space program.
Katherine G. Johnson’s calculations got us to the moon — but for many women studying and working in STEM (Science, Technology, Engineering, and Mathematics), race and gender can be a strong tether. Everyone brings their own assumptions to work. What’s difficult on the daily can be a range of unequal treatment, access, and bias, from micro-aggressions to sexual harassment.
Keystone Crossroads | Amazon Planning 2,500 Hires in N.J. As Part of Overall Expansion
Keystone Crossroads. | Web Story. | February 9, 2017.
Amazon plans to hire 100,000 workers in the next year and a half, with 2,500 of them in New Jersey.
While they are not minimum-wage jobs, the pace of work can be very demanding.
As a business, shipping is like real estate: Location is everything. That's why Amazon has eight fulfillment centers in Pennsylvania, seven in New Jersey, and two in Delaware to deliver to your door as quickly as possible. But John Carr, a spokesman for the International Association of Machinists and Aerospace Workers, said the "free" shipping from Amazon comes at a cost.
"Their performance standards are very, very high. When you meet one, they tend to ... raise that speed and standard of how many orders you can pick and pull and pack in a certain amount of time. And Amazon tracks that," Carr said. "I think a lot of these workers get hurt because of the pace that they have to maintain to meet the goals set by Amazon."
Machinists were behind at least one failed drive to unionize the warehouses. Company spokeswoman Lauren Lynch said Amazon gives warehouse workers the exact same benefits as other employees, including health insurance, retirement plans, paid parental leave, and company stock.
Invisible Coating Preserves Iconic Stone Structures Threatened by Decay
Princeton University - School of Engineering & Applied Science. | Web Story. | February 2, 2017.
The stone monuments of Italy's Certosa di Bologna cemetery have stood for more than two centuries as symbols of peace and eternity. But even stone does not last forever. So Enrico Sassoni, a visiting postdoctoral research associate in Princeton's Department of Civil and Environmental Engineering, is working to protect the marble monuments and even make them stronger.
"In spite of being apparently very durable, marble is actually sensitive to several deterioration processes," Sassoni said. "Environmental temperature variations cause the opening of cracks inside marble, and rain causes dissolution of the carved surface."
With the help of an international team, the Princeton researchers have developed a low-cost and nontoxic treatment that might someday help art preservation and conservation specialists.
How? By applying a thin film of a calcium compound commonly found in bones and teeth. This calcium compound, called hydroxyapatite, is formed by the reaction of a water-based phosphate salt solution and calcite, the mineral that makes up marble. The solution seeps into and binds cracks in the marble's surface.
Tiger of the Week: Nancy Rappaport ’82 Debuts ‘Regeneration,’ a One-Woman Show About Surviving Cancer
Princeton Alumni Weekly. | Web Story. | September 28, 2016.
Nancy Rappaport ’82 has devoted her entire career to medicine. A child psychiatrist and associate professor at Harvard Medical School, she’s worked in the Cambridge, Mass., public school system for over two decades. Rappaport says her specialty is “angry teenagers” — and something about her hearty laugh says she doesn’t usually have trouble keeping up.
In August 2015, she was diagnosed with early-stage breast cancer. With three children of her own — one currently in med school — the longtime runner (13 Boston Marathons and counting) says she was stopped in her tracks.
“That transition — going from a doctor to a patient — has really opened me up,” she says. “For me, it was early-stage breast cancer. For other people, it could be a mild heart attack, or a major depression. Those things are relatively common for doctors to manage, but still, it can feel like earth-shattering news.”
Tiger of the Week: Izzy Kasdin ’14, Connecting People With Princeton’s Past
Princeton Alumni Weekly. | Web Story. | August 24, 2016.
Izzy Kasdin ’14 is a proud local. She knows the rhythms of the town and University: how the campus fills and empties each year, marked by a calendar of beginnings, breaks, Reunions, and departures. She grew up in Princeton.
At 14, Kasdin began volunteering as a docent with the Princeton Historical Society, a non-profit committed to sharing its own sense of the “local.” In January, the organization named Kasdin as its new executive director.
“It was a complete shock,” Kasdin remembers. She says although she didn’t formally apply to the position, her return to Princeton “makes perfect sense.”
It was the Historical Society, after all, that first introduced her to the field of museum curation and preservation. As a teen, her first task was to greet visitors at the door. Then, in 2008, the Historical Society organized an exhibition about political participation and activism. At the closing of the exhibit, Kasdin remembers taking the time to carefully pack up a women’s suffrage banner.
Tiger of the Week: Ian Martinez '01, Poetry Slam Champion
Princeton Alumni Weekly. | Web Story. | July 27, 2016.
Fifteen blocks. That’s how far Puerto Rican spoken word poet Ian Martinez ’01 walks every Wednesday, blasting his pump-up playlist through his headphones.
For Martinez, it’s not just a walk through Seattle. It’s a step away from his “white-collar job” at Microsoft, and a step towards the microphone on the intense-yet-intimate stage at Jai Thai on Broadway, home of the Rain City Poetry Slam.
Though he considers himself to be a “real newcomer and rookie,” Martinez is the current Grand Champion of the Rain City Poetry Slam. He earned that title by winning the Rain City slam’s finals in April, which attracted 250 people.
“Spoken word is a unique art form because it combines storytelling, traditional verse, and wordplay,” Martinez says. “Your energy has to match the room’s, and then take it up a notch. If you deliver, and the room gives you back the love you put into the poem, that’s the greatest feeling an artist can have.”
Tiger of the Week: Glenn Shepard ’87, Medical Anthropologist, Ethnobotanist, and Field Researcher
Princeton Alumni Weekly. | Web Story. | July 6, 2016.
Glenn H. Shepard Jr. ’87 has a lush and noisy backyard: Toucans squawk, parrots chatter, monkeys howl. He lives in the middle of the jungle. Settled in Belém, at the mouth of the Amazon, Shepard works as a full-time researcher and ethnology curator at the Goeldi Museum in Belém do Pará, Brazil.
Some might say Shepard lives in paradise. Yet as an ethnobotanist — a researcher interested in how cultures use plants, especially as medicine — Shepard’s work focuses on illness, pain, and stress. Every culture, he says, has found ways to heal.
Shepard is a medical anthropologist who has dedicated himself to the Matsigenka, an indigenous people who live in Manú National Park, an isolated natural wonder deep within the Peruvian rain forest. This June, Shepard’s work was featured in National Geographic: “This Park in Peru Is Nature ‘in Its Full Glory’—With Hunters,” by Emma Harris.
On the Campus: Time to Celebrate | Special Ceremonies Recognize Paths Taken by Graduating Students
The Princeton Hidden Minority Council presented green graduation cords to 33 seniors during a ceremony May 15 for first-generation and low-income students. About 55 people attended the event in the Carl A. Fields Center. Speakers included council co-founders Brittney Watkins ’16 and Dallas Nan ’16 and management consultant Jeremy White ’96, who gave the keynote address.
About 600 people attended the Pan-African Graduation May 29 in Richardson Auditorium. Tennille Haynes, director of the Fields Center, said the event recognized students’ “hardships and their struggles. With sit-ins and protests, our students have been creative in finding ways to be heard.” Seniors Aisha Oxley and Kujegi Camara performed a spoken-word poem about learning to stand up for their identities as students of color.
The final scene of Stephanie Leotsakos ’16’s chamber opera, OMG, opens with a World War II veteran clasping an amulet to his heart, weeping about the memory of his mother, Anna. His daughter, Anna Francesca, walks into the room, distracted by her cellphone. Her Snapchats and emojis are projected onto the screen behind the stage; for a moment, the only music is the sound of screen swipes and texting. Then Anna looks up — and she sees her father crying. “OMG,” she sings, and drops her phone.
OMG, Leotsakos’ senior-thesis opera, premiered April 23 in Taplin Auditorium. The 51-minute production featured eight singers and 10 musicians. The story opens in A.D. 550 near the Church of San Vitale in Ravenna, Italy; over six scenes, it moves toward the present day.
“OMG is by far the most complex thing I have ever created,” said Leotsakos, who learned the violin at 3, the piano at 4, and the viola at 9. She started composing two years ago.
Philadelphia Business Journal | Princeton Plasma Physics Laboratory’s $94M Upgrade to World’s Most Powerful Fusion Experiment
Philadelphia Business Journal. Web Story. May 23, 2016.
The Princeton Plasma Physics Laboratory (PPPL) just celebrated a milestone in its research on fusion energy. After nearly four years of round-the-clock work by 250 people, the PPPL completed a $94 million upgrade to its flagship fusion facility, the National Spherical Torus Experiment (NSTX-U).
Department of Energy Secretary Ernest Moniz donned a white hard hat to tour the NSTX-U's test cell facility and the 85-ton machine at the center.
The NSTX-U is a fusion energy experiment contained in a spherical tokamak reactor. This design is an apple-core shape that requires less energy than traditional tokamaks, which are bulkier (and often more expensive to operate).
Like the sun, the NSTX-U is powered by fusion.
Tiger of the Week: Theater Director Lileana Blain-Cruz ’06 Brings Branden Jacobs-Jenkins ’06’s ‘War’ to Lincoln Center
Princeton Alumni Weekly. | Web Story. | May 11, 2016.
War, a new play directed by Lileana Blain-Cruz ’06 and written by Branden Jacobs-Jenkins ’06, premiered May 21 in New York at Lincoln Center’s Claire Tow Theater. It’s a story about family battles: Siblings Tate (Chris Myers) and Joanne’s (Rachel Nicks) relationship turns combative when their mother (Charlayne Woodard) has a stroke, and an inheritance is in limbo.
As director and playwright, Blain-Cruz and Jacobs-Jenkins are creative siblings, so to speak: They have supported one another for nearly a decade.
“Branden and I met as classmates,” says Blain-Cruz, a Yale M.F.A. grad who directed War’s world premiere at the Yale Repertory Theater last year. “We’ve each seen almost everything the other has done. And this play — a huge play about family and history — felt like the right piece for us to work on together.”
Tiger of the Week: Textile Artist Diana Weymar '91 Brings Her Craft to Princeton
Princeton Alumni Weekly. | Web Story. | April 20, 2016.
This spring, Diana Weymar ’91, a textile artist and curator based in Victoria, British Columbia, returned to Princeton. A mother of four, she left the view from her studio desk — a Blue Heron nest, grazing deer, a salty waft settling in, blocks from the ocean — to be the Anne Reeves Artist-in-Residence at the Arts Council of Princeton.
Weymar’s collaborative sewing project, “Interwoven Stories,” seeks to stich the Princeton community together.
“This project asks participants to stitch a page — and some are spending months on it — to then contribute to the community,” Weymar says. This spring, she led sewing workshops and handed out nearly 230 blank “pages” at the Princeton Public Library.
“So often we make something of importance or value to us and then keep or sell it,” she continues. “It’s a risk for some, and second nature to others. Each person has a different reaction to the blank fabric page.”
Tiger of the Week: Lauret Savoy '81, Earth Scientist, Map Reader, 'Memory Tracer'
Princeton Alumni Weekly. | Web Story. | March 30, 2016.
This is how Savoy, a professor of environmental studies and geology at Mount Holyoke College, describes the beloved map she’s carried for years — a large, “creased, taped, and re-taped” roll she’s unfurled on every cross-country trip since Princeton, “since that day in college when Professor Judson handed out copies to his geomorphology class.”
Savoy’s map, as she recalls in Trace’s fifth chapter, “What’s in a Name,” is a hand-drawn and inked copy by “master cartographer-artist” Erwin Raisz. It’s also something she “reads” — which suggests that Savoy sees her map as something more than the shaded, textured terrain of “physiographic landforms”; her map, like Trace, is a text.
The #BarefacedBeauty Campaign Wants Women to Go Make Up Free
Barefaced and Beautiful — what a concept. On Monday, in conjunction with National Eating Disorders Awareness Week (#NEDAwareness), the Renfrew Center Foundation is asking women to go “make-up free” for a day — something that might seem like no big deal. But there’s a small catch. The Renfrew Center, which is based in Philadelphia and has treated more than 65,000 women with eating disorders in its 30-year history, is asking women to take one more step: to post a make-up free, “untouched” selfie, and to share it with the world, using the the hashtag #barefacedbeauty.
According to this campaign, girls who decide to go with this “no-makeup look” are making a big statement. But is this a radical idea, really? And is this a new thing?
If this barefaced and beautiful idea sounds familiar, it’s because — well, it kind of is. This is the fifth year of Renfrew’s annual Barefaced and Beautiful campaign. Even former Princeton Prof. Melissa Harris-Perry posted her own selfie sans make-up on MSNBC, in a piece titled “The Naked Truth About Body Image.”
Tigers of the Week: From Triangle Club to Love Triangle, Playwrights Scott Elmegreen ’07 and Drew Fornarola ’06 Debut Off-Broadway Play
Princeton Alumni Weekly. | Web Story. | February 24, 2016.
The pair met at Theatre Intime and the Princeton Triangle Club in the fall of 2003.
“Triangle is a pre-professional kind of experience,” said Fornarola before a Thursday night performance of Straight in New York. “It’s as close to what it’s like to do a show here as I imagine most people could have in college.
“You’ve got a creative team. You’ve got investors that you present a show to, and they give you feedback. You’ve got audiences to think about. It’s a big budget show on a big stage. The chance to do that twice a year is second to none.”
Tiger of the Week: Nushelle de Silva '11, Building Bridges in Sri Lanka
Princeton Alumni Weekly. | Web Story. | January 27, 2016.
Nushelle de Silva ’11 grew up in Sri Lanka. In 1983, before she was born, the country erupted in what would be a 25-year civil war.
“My parents, who were fairly young at the time, saw the horrific violence that erupted on the streets,” she says. Then, she pauses. “I don’t want to provide details that run the risk of flattening what was a very complex conflict.”
Sri Lanka is a country that de Silva’s parents left and returned to — despite the civil war. After a stint in Sydney, Australia, where Nushelle was born, the family moved to Colombo, the southwestern capital, when she was 7.
In 2004, during a ceasefire, de Silva’s K-12 all-girls’ school visited a sister school in Jaffna, the country’s northernmost city. “It had a huge impact on me as a young girl,” she remembers.
Princeton Echo | Heart in Princeton, Head in the Clouds
Michael Lemonick has marked many seasons in Princeton. He was born and raised here. He’s watched the winter turn to spring year after year. And when he talks about the weather, it’s not small talk.
For three decades, Lemonick has been one of the nation’s eminent science writers, notably for Time Magazine, for which he wrote more than 50 cover stories. In November, he became the opinion editor at Scientific American. And in between, he spent seven years as the senior science writer at Climate Central, the Palmer Square-based nonprofit, nonpartisan research and media organization that employs climate scientists, researchers, fellows, and journalists.
Lemonick knows it’s been a warmer winter. But, he says, that doesn’t mean we should assume this year’s milder temperatures are due to climate change — especially since last year’s winter was quite cold.
“The fact that it’s warmer this year than last year? No. That has nothing to do with climate change,” he says. “The fact that, on average, it’s warmer in every state in the winter than it was in 1900, and that it’s been steadily rising? Yes, that has everything to do with climate change.”
Tiger of the Week: David Zabel ’88, Television Writer, Producer, and Co-Creator of ‘Mercy Street’
Princeton Alumni Weekly. | Web Story. | December 16, 2015.
On Dec. 7, in front of a full-house audience of star-struck undergraduates and artsy locals, David Zabel ’88 spoke from a stage that supported the early days of his career — literally. It was at 185 Nassau, the longtime home of the arts at Princeton, that he spent hours and hours at late-night rehearsals and intensive writing workshops.
Once he discovered the theater at Princeton, Zabel said, his other interests (history, for example) quietly faded away. It snapped his future into focus.
“I was interested in a bunch of different things,” he said. “It was just theater that embraced me — earliest and most fully.”
Zabel is now an award-winning television writer, producer, and director. He wrote more than 45 episodes of ER, the medical series on NBC. He was the showrunner of ER for the program’s final five years, and he was also the showrunner and executive producer of Detroit 1-8-7 and Betrayal (both on ABC).
Tiger of the Week: Daniel Velasco ’13, Teach for America Alum and Charter School Mentor Teacher
Princeton Alumni Weekly. | Web Story. | November 18, 2015.
Outside Daniel Velasco ’13’s classroom window at the 21st Century Charter School in Gary, Ind., stands an abandoned building with boarded up windows. But the view doesn’t bother Velasco — his focus is on his students, not his surroundings.
“I absolutely love all of my students, even those that make me want to pull my hair out,” Velasco said with a chuckle. “The greatest lesson I have learned from them is patience.”
This is Velasco’s third year at the charter school. During his first two, he taught full time as a Teach for America fellow. Velasco taught AP United States history, AP world history, economics, government, and world history. He has also tried to build relationships with his students, and to connect with them as a mentor.
“When I teach my kids, stay after school with them, and host tutoring sessions during breaks, I think about the teachers that did that for me,” he said.
Princeton Echo | Award-Winning Poet Tracy K. Smith is Living 'the Good Life’ in Princeton
On a windy night in September, Tracy K. Smith — cloaked in an elegant gray frock that was wrapped in a mysteriously tidy way, as if by magic — was the picture of a professor. A sea of eager undergraduates set their phones to “silent” and tucked their pea coats, book bags and pumpkin spice lattes under their seats. Alone in the front row, Smith sat quietly, listened intently. And then, as if lit by a lamp from within, she warmed up, smiled and walked to the podium.
Smith, a Pulitzer Prize-winning poet, memoirist, and professor of creative writing at Princeton University, had been invited to be the keynote speaker for the Princeton University Women’s Mentorship Program’s annual kick-off event. Under the gothic chandeliers of Mathey College’s Common Room, Smith unfolded her notes and began.
“In my first years as a teacher,” Smith said from the podium, “I wanted to feel solidarity with my students. So, I completed the assignments I gave them. I wrote what they wrote.”
Tiger Of The Week: Publishing Veteran John Oakes ’83
Princeton Alumni Weekly. | Web Story. | October 28, 2015.
In September, John Oakes ’83, a veteran book publisher based in New York, returned to the Princeton campus for “Careers Beyond Wall Street,” a panel sponsored by Princeton Progressives. He described a shrinking industry that is, well, still stuck in the Stone Age.
“I think going into book publishing — certainly the traditional side of it — is tantamount to apprenticing yourself to a potter. Or a stone carver,” he said.
Book publishing is “quaint, time-consuming, frustrating, and occasionally thrilling,” he said — and it’s in the midst of a massive transformation.
As the co-publisher at OR Books, an independent press that sells e-books and paperback books direct to readers, and prints on demand, Oakes is shaping that transformation, one book at a time. In the coming year, Oakes also plans to re-launch The Evergreen Review, a groundbreaking literary magazine, with Editor-in-Chief Dale Peck.
Tiger of the Week: Documentary Filmmaker Elizabeth Chai Vasarhelyi ’00
Meru, a Sundance Audience Award-winning white-knuckler of a documentary, follows three elite mountain climbers on their quest to conquer the 21,000-foot summit of Mount Meru, the most technically difficult peak in the Himalayas. It’s a death-defying expedition into sub-zero temperatures that involves extraordinary risks.
But the mission that climbers Conrad Anker, Renan Ozturk, and Jimmy Chin share is not only physically grueling; it’s emotional. Meru tests their friendship, and their relationships with their families back home.
No one knows this better than Elizabeth Chai Vasarhelyi ’00, who co-directed and co-produced the film with Chin. The directors fell in love through the making of Meru, and they married in 2013. Now, they split their time between the Upper East Side of New York City and the big blue skies of Jackson Hole, Wyo.
Tiger of the Week: Allegra Wiprud ’14, Conservation Leader
Princeton Alumni Weekly. | Web Story. | September 30, 2015.
Allegra “Lovejoy” Wiprud ’14 gets emotional when she recalls her first land stewardship trip at the D&R Greenway Land Trust, an 18,000-acre land preservation and conservation nonprofit. It was an invasive species removal job in Hopewell, N.J. That day, the dangerous plant that her team tracked down, cut back, and destroyed — the climbing growth that covered, choked, and threatened to kill a tree — was English ivy (Hedera helix).
Perched on a picnic table outside the Johnson Education Center, a historic barn overlooking Greenway Meadows, Wiprud mimes how she removed the ivy, grabbing the vine with her hands as if it were a snake coiled around her neck. By clearing the ivy away, she says, “We can give the tree its life back.”
Ivy might look quintessentially Princeton, but as Wiprud is learning, the non-native plant climbs and grows so fast that it smothers other plants and starves trees of sunlight.
Tiger of the Week: Patrick Ryan ’68, Gallery Director
Princeton Alumni Weekly.| Web Story. | August 26, 2015.
Patrick Ryan ’68 doesn’t do “art speak.” But he does know how to command the stage at an auction, rattling off antiques and art at break-neck speed to the highest bidder. Last Saturday, at the historic Benjamin Temple house and dairy farm in Ewing, N.J., where he was born and raised, Ryan auctioned off more than 80 items in 2 1/2 hours under a blazing hot sun — all for charity, to support the Ewing Township Historic Preservation Society.
Ryan has led a life of talking fast and moving faster. A long-time art collector and gallery owner, Ryan is just as comfortable in overalls and work boots as in seersucker shorts and a polo shirt.
He reckons he somehow “inherited the Irish gypsy gene,” a drive that rattled against the quiet rituals of his father’s 166-acre dairy farm: rising at 4:30 a.m. to milk 50 cows, twice per day. “The cows don’t care if it’s Christmas,” he remembers.
Tiger of the Week: Keyboardist Gavin Black ’79
Princeton Alumni Weekly.| Web Story.| August 12, 2015.
Gavin Black ’79 has devoted his entire adult life to studying, performing, teaching, and recording 17th- and 18th-century keyboard music. But he knows that studying Baroque music on antique instruments isn’t an easy sell.
“The harpsichord is not remotely as popular as the piano,” he laughs from a bench at the Princeton Early Keyboard Center, the non-profit music studio he founded in 2001. It offers harpsichord, clavichord, and organ lessons for students, composers, and group classes.
Black discovered the organ and harpsichord at age 14, after a stint taking piano lessons left him curious about Baroque music.
As a freshman at Princeton, he would practice the organ alone in the vast and empty University Chapel, lit only by moonlight, courtesy of a special access key.
Princeton Echo | Classics You Can't Refuse: Garden Theatre Hooks Princeton in Throwback Hollywood Film Series
Megan Connor is a budding film buff. She's headed to the New York Film Academy this fall, and she's also a member of the nonprofit Princeton Garden Theatre on Nassau Street. She believes in movies. Even older ones. But she’s not convinced that the classics have any bite left — even Jaws.
“Jaws isn’t going to be scarier on the big screen — it’s like 40 years old!” Connor, 18, rolled her eyes with a playful smirk in the lobby of the Garden Theatre on June 25. As a Millennial, Connor was raised on easy, 24/7 access to small screen entertainment. At the Garden Theatre, she's learning to love old movies — but with a filter of ironic nostalgia, because "classic" is cool, and "vintage" is hip.
Planet Princeton | Princeton Resident Michael Dean Morgan Makes His Debut on Broadway in ‘Amazing Grace’
“It’s a popular venue. You just gotta sing clearly for the grandmas in the back.”
In the balcony of the Nederlander Theater on 208 W. 41st St. in New York City, after a Saturday preview matinée, Michael Dean Morgan talks easily over the clatter of mic checks, an active orchestra pit, and a tour below. Even the noise of a yodeling voice warming up backstage doesn’t faze him.
