Twist on famous double-slit experiment deals a blow to Einstein’s quantum doubts // Gizmodo
MIT researchers recently performed a new “iteration of a foundational quantum experiment.” The physicists “successfully replicated the double-slit experiment on the atomic scale, allowing for an unprecedented level of empirical precision.”
The LIGO Lab is pushing the boundaries of gravitational-wave research // Scientific American
Ten years after scientists detected gravitational waves for the first time using the LIGO detectors, Rachel Feltman of Scientific American’s “Science Quickly” podcast visits the MIT LIGO Lab to speak with Associate Professor Matthew Evans about the future of gravitational wave research.
Superhot geothermal energy could unearth big power boost for the AI era // CNBC
CNBC spotlights Quaise Energy, an MIT spinoff developing geothermal energy technology.
Puzzling
We got you started on a recent crossword puzzle from The New York Times. Can you fill out the rest of the grid?
Watch This
In MIT course 21T.221 (Lighting Design), students explore the history, concepts, and techniques of sculpting space with light within a contemporary context. Taught by Joshua Higgason, professor of the practice in design for MIT Theater, students experiment with a wide range of approaches, tools, and skills to develop their own creative vision. The course focuses on forms that include live performance, installation, architecture, and developments in applied technologies. It allows students, Higgason says, “to create new ways to share their art and to share their story with other people.”
