Irvin Glassman, ‘Grand Old Man of Combustion,’ dies at 96

Irvin Glassman, a leading authority on combustion and propulsion who served on the Princeton faculty for 49 years, died Dec. 14, 2019, at his home in Princeton. He was 96.

New rules illuminate how objects absorb and emit light

Princeton researchers have uncovered new rules governing how objects absorb and emit light, fine-tuning scientists' control over light and boosting research into next-generation solar and optical devices.

Real-life examples bring new energy to core thermodynamics course

This year, the mechanical and aerospace engineering department's thermodynamics class became a Campus as Lab course, featuring field trips, guest lectures and lessons that enhanced students’ learning with examples of energy technology and policy from the University campus and surroundings.

'Grow-and-prune' AI mimics brain development, slashes energy use

In a pair of papers published earlier this year, researchers showed how to start with a simple design for an AI network, grow the network by adding artificial neurons and connections, then prune away unused portions leaving a lean but highly effective final product. Growing and pruning results in software that requires a fraction of the computational power, and so uses far less energy, to make equally good predictions about the world. Constraining energy use is critical in getting this kind of advanced AI — called machine learning — onto small devices like phones and watches.

New technology boosts energy efficiency in data centers

Minjie Chen, an assistant professor of electrical engineering and the Andlinger Center for Energy and the Environment, and his team are building a family of devices to dramatically reduce power consumption at the gigantic data centers that serve as the backbone of internet services and cloud computing.

Freedman, Singh named fellows of Association for Computing Machinery

Princeton computer science professors Michael Freedman and Mona Singh have been named fellows of the Association for Computing Machinery in recognition of their significant contribution to computing and information technology. This year, the association named 58 new fellows from research centers, companies and universities around the world.

Research reveals a singular moment: when a bubble breaks free

Princeton researchers describe the break-up of a bubbles surrounded by turbulent flows like those found in industrial processes or in nature.

Pac-Man-era microchip could help gobble up nuclear warheads

Princeton researchers have proposed using vintage electronics to verify nuclear disarmament.

Stone and Sturm named to National Academy of Inventors

The National Academy of Inventors has named Princeton engineering professors Howard Stone and James Sturm among 168 fellows for 2019.

Optical switch illuminates cells' development

Combining light and a protein linked to cancer, researchers at Princeton University have created a biological switch to conduct an unprecedented exploration of cellular development in the embryo.
