Ask physicist Sekazi Mtingwa how he ended up the place he’s in the present day, and he’ll begin together with his grandmother’s deeply non secular dwelling. Rising up there in Atlanta, younger Mtingwa by some means acquired the concept he was the second coming of Christ.
“I believed that for years,” Mtingwa recollects with fun. That solely modified after a Sunday faculty lesson as a schoolboy. It was about Jesus sacrificing himself for murderers and thieves. “I regarded across the room, and all these unhealthy boys in my class, I couldn’t give my life for any of them — not to mention murderers,” he says.
That was it for the Jesus plan, Mtingwa says. However his want to serve humankind by no means waned. Right now, says Mtingwa, who stays non secular, “I like to consider myself as an apostle of science.”
Apostle of science will get near the essence of Mtingwa’s profession. Over the many years, he’s had {many professional} titles. As an accelerator and particle physicist, Mtingwa is nationally acknowledged for his work constructing accelerators and for creating the idea of how particles scatter once they’re squeezed into high-energy beams. However he’s additionally a nuclear coverage knowledgeable, mentor, administrator, activist and founding father of dozens of organizations in the USA and overseas devoted to creating new alternatives in science for individuals who have been traditionally stored at its margins.
“Individuals’s on a regular basis lives are impacted and improved by his efforts,” says Robbin Chapman, one in every of Mtingwa’s mentees who’s now affiliate dean for variety, inclusion and belonging at Harvard Kennedy College. That impression is expansive, says Chapman, “whether or not it’s the precise analysis, whether or not it’s the instructing or whether or not it’s the networks he’s bringing collectively throughout nations and continents.”
A brand new idea and a brand new identify
Born in 1949, Mtingwa attended segregated faculties in Georgia. Again then, he had a unique identify — Michael Von Sawyer. Different youngsters teased him for the identify, he says, calling him a “mad German scientist.” Having given up on being Jesus, Mtingwa says, “I needed to search for one other profession.” All that jeering acquired him considering it is perhaps science.
Mtingwa devoured books about science on the native library and concocted a mission that gained him first place in botany at Georgia’s state science honest. It was the primary yr that the competition was racially built-in. His science honest prize included a field of science books. A number of have been on common relativity. And with that, his curiosity in physics ignited.
As an undergraduate at MIT, Mtingwa studied physics and arithmetic and discovered to channel his ambition to serve others into activism. It was the “turbulent Nineteen Sixties,” Mtingwa says, and the campus zeitgeist crackled with the power of the Civil Rights Motion and Vietnam Struggle protests. He acquired concerned in pupil teams advocating for racial fairness, was a founding member of MIT’s Black College students’ Union, and, together with different college students, he participated in a takeover of a school lounge.
“That basically drove into me the necessity to serve,” he says. “However I at all times had this philosophy you could’t serve till you first deal with your self — higher your self, get your training, set up your profession.” After that, he believes, one can begin to attain out to assist particular person individuals and, finally, construct programs that transcend people to the world.
After MIT, Mtingwa earned his Ph.D. at Princeton College engaged on high-energy particle physics. It was throughout that point that Mtingwa, a Pan-Africanist, selected his identify with the assistance of a fellow graduate pupil from Tanzania. Shortly after graduating, he joined different Black physicists to discovered the Nationwide Society of Black Physicists in 1977. He’d met a number of of his cofounders at MIT, which he describes as having been a form of hub for Black physicists.
However Mtingwa says his educational profession almost ended just some years later. After two postdocs, he struggled to discover a job at the same time as his white colleagues appeared to drift up the educational ladder. A Ford Fellowship he acquired in 1980 saved him, he says, sending him to Fermilab, a number one particle physics laboratory in Batavia, Unwell., for a yr.

That yr snowballed into seven, throughout which he and theoretical physicist James Bjorken developed the idea of intrabeam scattering — which describes how charged particles unfold out when packed collectively into high-energy beams. In particle accelerators, which create high-energy beams and infrequently use them to smash particles collectively or into different targets, this spreading can damage efficiency if it’s not correctly accounted for. The speculation Mtingwa helped develop has been put to work within the design of particle accelerators the world over, from small synchrotrons used to generate intense gentle for chemistry and biology experiments to the Massive Hadron Collider at CERN, close to Geneva.
“Any accelerator physicist is aware of in regards to the Bjorken-Mtingwa idea,” says accelerator physicist Mark Palmer of Brookhaven Nationwide Laboratory in Upton, N.Y. “This has had a really, very deep impression on broad parts of the scientific endeavors that depend upon accelerator efficiency with very-high-energy beams.”
Opening science to others
Mtingwa continued his work on the theoretical physics of particle accelerators. However he additionally began to construct them.
At Fermilab, he helped design programs for producing and gathering antiprotons — the antimatter counterpart to protons — so that they might be accelerated into beams. Colliding streams of protons and antiprotons in Fermilab’s Tevatron accelerator in the end revealed the existence of the highest quark, a basic particle. Not solely is the highest quark an important piece of the usual mannequin of particle physics, however its massive mass can be helpful for testing the mannequin.

And at Argonne Nationwide Laboratory in Illinois, Mtingwa labored out the theoretical underpinnings of plasma wakefield accelerators — a kind of particle accelerator that accelerates particles utilizing pulsing waves of plasma, which Argonne scientists experimentally demonstrated for the primary time in 1988.
In 1991, after years working at a number of the prime nationwide laboratories, Mtingwa decided that he says baffled his colleagues: He grew to become a professor at North Carolina Agricultural and Technical State College in Greensboro, a traditionally Black college that, again then, didn’t have a graduate program in physics in any respect.
“I had at Fermilab and at Argonne labored with college students — highschool and school — for the summer season. And I had gotten eager about surrounding myself with the younger, African American college students to strive to have the ability to make a distinction,” Mtingwa says.
Mtingwa had taken care of himself. Now, he wished to begin caring for others.
At North Carolina A&T, Mtingwa established a grasp’s program in physics and laid the groundwork for brand spanking new Ph.D. packages. Over his a few years instructing at North Carolina A&T, Morgan State College, Harvard and his alma mater MIT, he mentored numerous individuals, together with Chapman — who now mentors college students herself.
“He actually captured what I noticed is the essence of supporting anybody, however notably students of coloration as they’re transferring by way of their educational careers,” she says. Fairly than seeing life and work as separate issues, Mtingwa taught Chapman to see them as a part of one ecosystem of excellence. “He’s a programs thinker,” she says, with a eager eye for a way individuals match into their full context and what which means for a way they work.
Right now, Mtingwa is in what he describes as “that third stage” of serving the world: constructing establishments. When he talks about this stage, his tales deal with “we” greater than “I,” to the purpose that it turns into exhausting hold monitor of which “we” he’s speaking about. Over his lengthy profession, he’s constructed, nurtured after which fastidiously entrusted to others a dozen or so packages, establishments and nonprofits.

Mtingwa helped discovered not solely the Nationwide Society of Black Physicists, but additionally the Nationwide Society of Hispanic Physicists and the African Bodily Society, amongst a number of different skilled organizations in the USA and overseas, with a deal with locations the place scientific infrastructure and alternatives are extra restricted. He’s actively main efforts in Africa, the Caribbean, the Center East and Asia to coach scientists to make use of synchrotron gentle sources — small particle accelerators that generate intense gentle which are very important for a lot of forms of analysis in chemistry and biology — and construct synchrotron gentle supply services.
The purpose, Mtingwa says, is to create extra alternatives for extra individuals in science. He’d wish to see a day with out discrimination, when anybody’s scientific careers may flourish — regardless of who or the place they’re.
“I noticed I wasn’t Jesus Christ,” Mtingwa says. “However I used to be placed on Earth to serve mankind, in order that’s what I’m making an attempt to do now – to be of service.”
