Try to picture a proton — the minute, positively charged particle within an atomic nucleus — and you may imagine a familiar, textbook diagram: a bundle of billiard balls representing quarks and gluons. From the solid sphere model first proposed by John Dalton in 1803 to the quantum model put forward by Erwin Schrödinger in […]

MIT scientists develop low-cost, high-precision fabrication method for thin mirrors and silicon wafers
Technologies that depend on lightweight, high-precision optical systems, like space telescopes, X-ray mirrors, and display panels, have developed significantly over the past several decades, but more advanced progress has been limited by seemingly simple challenges. For example, the surfaces of mirrors and plates with microstructures that are necessary in these optical systems can be distorted […]
School of Science announces 2022 Infinite Mile Awards
The MIT School of Science has announced the winners of the 2022 Infinite Mile Award. The selected staff members were nominated by their colleagues for going above and beyond in their roles at the Institute. Their outstanding contributions have made MIT a better place. The following are the 2022 Infinite Mile Award winners in the […]
Learning to think critically about machine learning
Students in the MIT course 6.036 (Introduction to Machine Learning) study the principles behind powerful models that help physicians diagnose disease or aid recruiters in screening job candidates. Now, thanks to the Social and Ethical Responsibilities of Computing (SERC) framework, these students will also stop to ponder the implications of these artificial intelligence tools, which […]
Finding the questions that guide MIT fusion research
“One of the things I learned was, doing good science isn’t so much about finding the answers as figuring out what the important questions are.” As Martin Greenwald retires from the responsibilities of senior scientist and deputy director of the MIT Plasma Science and Fusion Center (PSFC), he reflects on his almost 50 years of […]
QS World University Rankings rates MIT No. 1 in 12 subjects for 2022
MIT has earned a No. 1 spot in 12 subject areas, according to the QS World University Rankings for 2022, announced today. The Institute received a No. 1 ranking in the following QS subject areas: Architecture/Built Environment; Chemistry; Computer Science and Information Systems; Chemical Engineering; Civil and Structural Engineering; Electrical and Electronic Engineering; Materials Science; […]
MIT graduate engineering, business, science programs ranked highly by U.S. News for 2023
MIT’s graduate program in engineering has again topped the list of U.S. News and World Report’s annual rankings, released today. The program has held the No. 1 spot since 1990, when the magazine first published these rankings. The MIT Sloan School of Management also placed highly, landing in the No. 5 spot for the best […]
Scientists develop the largest, most detailed model of the early universe to date
It all started around 13.8 billion years ago with a big, cosmological “bang” that brought the universe suddenly and spectacularly into existence. Shortly after, the infant universe cooled dramatically and went completely dark. Then, within a couple hundred million years after the Big Bang, the universe woke up, as gravity gathered matter into the first […]
Physicists find direct evidence of strong electron correlation in a 2D material for the first time
In recent years, physicists have discovered materials that are able to switch their electrical character from a metal to an insulator, and even to a superconductor, which is a material in a friction-free state that allows electrons to flow with zero resistance. These materials, which include “magic-angle” graphene and other synthesized two-dimensional materials, can shift […]
A fabric that “hears” your heartbeat
Having trouble hearing? Just turn up your shirt. That’s the idea behind a new “acoustic fabric” developed by engineers at MIT and collaborators at Rhode Island School of Design. The team has designed a fabric that works like a microphone, converting sound first into mechanical vibrations, then into electrical signals, similarly to how our ears […]
Yen-Jie Lee probes particle collision data for clues to the universe’s origins
When Yen-Jie Lee came to MIT as a graduate student in 2006, it was a bit of a culture shock. The aspiring particle physicist had studied physics at National Taiwan University before his career took a hiatus in the forested mountains of Taiwan. There, he worked as a marine corps lieutenant to fulfill the nation’s […]
More sensitive X-ray imaging
Scintillators are materials that emit light when bombarded with high-energy particles or X-rays. In medical or dental X-ray systems, they convert incoming X-ray radiation into visible light that can then be captured using film or photosensors. They’re also used for night-vision systems and for research, such as in particle detectors or electron microscopes. Researchers at […]
Physicists observe an exotic “multiferroic” state in an atomically thin material
MIT physicists have discovered an exotic “multiferroic” state in a material that is as thin as a single layer of atoms. Their observation is the first to confirm that multiferroic properties can exist in a perfectly two-dimensional material. The findings, published today in Nature, pave the way for developing smaller, faster, and more efficient data-storage […]
