As Philadelphia prepares to host six FIFA World Cup 26 matches, Paulo Arratia (@MEAM_Penn) breaks down the science of natural grass vs. synthetic turf.
Natural grass absorbs energy and cushions impact, while turf is more rigid, affecting traction, ball movement and player biomechanics. “Beneath the cleats or tennis shoes, there’s a world of applied physics and mechanical processes at play,” says @ArratiaPaulo.
Philadelphia's matches begin Sunday with Côte d'Ivoire vs. Ecuador.

A new mathematical shape is challenging long-held assumptions about visual paradoxes.
Penn Engineering's Robert Ghrist (@prof_g, @eseatpenn) coauthored a Scientific American article with Zoe Cooperband of @USNRL on the "impossible Klein ladder," the first known impossible object to exhibit a nonabelian property, which happens when the order of two loops changes the outcome.
“The essence of a paradox is: you walk around a loop, and something has changed,” says Ghrist. “It’s a mismatch between where you are and where you thought you were.”

In EAS 5500: Applying Your Thesis to the Real World, Penn Engineering Ph.D. students explore how their research can create real-world impact. Taught by @VanessaZChan, the course explores the market, policy, manufacturing and adoption challenges that shape whether new technologies succeed beyond the lab.

"When the answer isn't obvious, when the incentives are loud and the timelines are tight, may our class have the integrity to pause. To think. To choose wisely."
Watch remarks from Penn Engineering's 2026 Undergraduate Speaker, Julia Fremberg (ENG'26).

Congratulations to Harrison Chong (MEAM’27, W’27) on being named to the @Forbes 30 Under 30 Asia 2026 list in the Social Impact category.
Chong cofounded Jalan Journey, a social enterprise that creates online educational games designed to help students develop emotional skills and engage more deeply with social issues. Since its founding in 2022, the platform has reached more than 25,000 learners across Southeast Asia.
“When I started Jalan Journey, I simply wanted to create learning experiences that helped young people feel, reflect, and care more deeply,” says Chong. “To have that work recognized by Forbes is surreal and deeply humbling. It reminds me how far I have come, but also how much more I have to do.”
Congratulations, Harrison!

Quantum science is becoming more hands-on at Penn Engineering thanks to ESE 3200: The Qubit Lab, where students work directly with optical and solid-state quantum experiments using research-grade equipment from @thorlabs.
Led by Lee Bassett and Anthony Sigillito (@Penn_ESE), the course brings quantum concepts to life.
Interested students can register for ESE 3200: The Qubit Lab in Fall 2026.

Ottman Tertuliano, AMA Family Assistant Professor in @MEAM_Penn, has been selected into the 2026 CIFAR Global Scholars program (@CIFAR_News).
Tertuliano's research explores how cells communicate mechanically within bone tissue during development and is already expanding into new collaborative questions, including how changes in the mechanical properties of the placenta during pregnancy could help predict health outcomes.
The CIFAR Global Scholars program supports emerging research leaders worldwide through collaborative opportunities, international convening and unrestricted research funding.

Congratulations to Penn Engineering's Class of 2026!
In her speech, student speaker Julia Fremberg (ENG’26) drew a parallel between Penn’s interconnected buildings and the vital bonds between students.
"As you move from place to place, from goal to goal, never forget to cherish those in-between moments. The E-Quad tunnels were never just about getting somewhere faster. They were about who you found—and who you became—along the way."

Penn Engineering’s Class of 2026 master’s graduates have turned their tassels and are prepared to step into the next chapter equipped with the knowledge, experience and determination they’ve accumulated at Penn.
Keynote speaker Vanessa Lyon (GEng'24) encouraged the graduates to embrace lifelong learning and use their skills to solve humanity’s biggest challenges: "Tools change fast. Faster than you realize. What doesn't change is your ability to reason about what's underneath."
Congratulations, master's graduates!
