Creativity takes many forms at Caltech. This May, through Caltech Performing and Visual Arts, experience the largest MACH 33 season in Caltech history, along with year-end performances in music and the performing arts by Caltech students, community members, and local groups.

The month also features Seminar Day with the Caltech Alumni Association and a conversation hosted by the Division of the Humanities and Social Sciences on trust between universities and society.

How can AI help people and protect the environment?

In his Science Journeys talk, Smarter AI for a More Sustainable World, Caltech student Chris Yeh explores how AI can support scientists, conservationists, and engineers making real-world sustainability decisions.

One challenge: AI can make predictions, but it generally cannot show how certain it is in those predictions. Chris’s research focuses on helping AI systems better communicate uncertainty so people can better judge how to use the results.

His Science Journeys talk is available to watch on Caltech’s YouTube channel: https://www.youtube.com/watch?v=WGHsa7Y-Ktc&list=PL8_xPU5epJdeCLXW_O2g84uJyZ4IPOJWc

It’s Earth Week! Caltech has long been at the forefront of sustainability research, from foundational air pollution studies that helped inform the Clean Air Act of 1970, to new chemistries for energy storage, to developing a new approach to climate modeling.

This week, join us for three events exploring the intersection of science, art, and the environment:

Tuesday: Get a sneak peek at a reading of The Heat of the Sun’s Rays, a science-driven play from the MACH 33 Festival.

Wednesday, Earth Day: Watch “The Spectrum of Life,” a documentary about NASA’s first biodiversity airborne campaign, BioSCape, in South Africa.

Saturday: Experience a concert composed by seismologist Lucy Jones and performed by the Colburn Baroque Ensemble, featuring researchers from Caltech’s Linde Center for Global Environmental Science in conversation about the drivers and projected consequences of climate change.

After the 2025 Eaton Fire, many were left with difficult questions about environmental exposure and cleanup, including Caltech professor of geochemistry Francois Tissot and his family. In his Watson Lecture, Tissot explains the need for more research around urban fires and how we can better protect communities in the future.

Hold out your arm and raise your pinky. How many galaxies do you think are hidden from view?

The Hubble Ultra-Deep Field (HUDF) is an image of a tiny region of space that contains about 10,000 galaxies. In the area covered by the tip of your pinky held at arm’s length, about 25 Hubble Ultra-Deep Fields could fit.

Henrietta Swan Leavitt and Vera Rubin made groundbreaking contributions at a time when women were often excluded from science and astronomy. Because of their trailblazing work, Caltech astrophysics graduate student Sam Rose is advancing research at the forefront of science using powerful telescopes on Earth and in space.
