  • The motion of fluids in nature, including the flow of water in our oceans, the formation of tornadoes in our atmosphere, and the flux of air surrounding airplanes, have long been described and simulated by what are known as the Navier–Stokes equations.Yet, mathematicians do not have a complete understanding of these equations. While they are […]
  • Astronomers at Caltech have used a machine learning algorithm to classify 1,000 supernovae completely autonomously. The algorithm was applied to data captured by the Zwicky Transient Facility, or ZTF, a sky survey instrument based at Caltech's Palomar Observatory."We needed a helping hand, and we knew that once we trained our computers to do the job, […]
  • More than 150 people, including Caltech leaders, alumni, students, faculty, and employees, along with other members of the local community, gathered on Thursday, November 17, to formally dedicate the Lee F. Browne Dining Hall, Caltech's central dining facility.The dining hall was named in the fall of 2021 in honor of the late Lee Franke Browne, […]
  • Engineers at Caltech and the University of Southampton in England have collaboratively designed an electronics chip integrated with a photonics chip (which uses light to transfer data)—creating a cohesive final product capable of transmitting information at ultrahigh speed while generating minimal heat.Though the two-chip sandwich is unlikely to find its way into your laptop, the […]
  • New Caltech research is showing how devices implanted into people's brains, called brain-machine interfaces (BMIs), could one day help patients who have lost their ability to speak. In a new study presented at the 2022 Society for Neuroscience conference in San Diego, the researchers demonstrated that they could use a BMI to accurately predict which […]
  • More than 5,000 exoplanets, or planets that orbit stars beyond our sun, have been spotted over the last 30 years, and discoveries from space and ground-based telescopes continue to roll in. The planets come in many sizes and compositions and include everything from molten lava worlds to gas giant planets larger than Jupiter. However, the […]
  • Electrons—those little subatomic particles that help make up the atoms in our bodies and the electricity flowing through your phone or computer right now—have some properties like mass and charge that will be familiar to anyone who has taken a high school physics class. But electrons also have a more abstract property known as spin, […]
  • On November 12, the Caltech Seismological Laboratory—the Seismo Lab, for short—will celebrate its centennial, marking an unparalleled century at the forefront of earthquake science and geophysics.Founded in 1921 by prominent seismologist Harry Wood, the Seismo Lab actually reached the centennial milestone last year, but restrictions on gatherings to combat the COVID-19 pandemic delayed the official […]
  • The Division of Physics, Mathematics and Astronomy (PMA) recently welcomed Shawna Silesky as its new division operations officer (DOO), charged with overseeing operations, finances, human resources, and other crucial administrative functions.Fiona Harrison, the Harold A. Rosen Professor of Physics and the Kent and Joyce Kresa Leadership Chair of the Division of Physics, Mathematics and Astronomy, […]
  • Leon Silver (PhD '55), W. M. Keck Foundation Professor for Resource Geology, Emeritus, at Caltech, passed away on January 31, 2022. He was 96 years old.Silver was born in Monticello, New York, on April 9, 1925, the youngest of seven children, two of whom did not survive to adulthood. His father and mother emigrated from […]
