Aliso Canyon, Methane, and Global Climate

04-18-16

The Aliso Canyon underground storage facility for natural gas in the San Fernando Valley—the fourth largest of its kind in the United States—had one of its wells blow out on October 23, 2015, leading to a large release of methane. In a recent conversation, Professor Paul Wennberg discusses enormous methane and carbon dioxide (CO2) emissions, and their troubling implications for global climate. “If we could really knock the methane emissions back to what they were before people started emitting methane, it would be a large change. It would be a half a watt per meter squared. The total global warming would drop by around 25 percent,” Professor Wennberg explains. [Caltech story]

Using Applied Physics to Explain How Accretion Disks Drive Astrophysical Jets

04-01-16

Paul M. Bellan, Professor of Applied Physics, has developed a new model explaining why astrophysical jets always originate from stars having accretion disks, the progenitors of planets. The relationship between jets and accretion disks has eluded scientists for many years and what happens to the angular momentum of accreting particles has also long been a mystery. Professor Bellan’s model explains how the disks power the jets as well as how angular momentum is removed from accreting material in the disks. The model involves peculiar inward spiraling trajectories of clumps of charged and neutral particles, and shows that the disk and jets together form an electric circuit where the disk is the battery and the jet is the load.

Living—and Giving—the Caltech Dream

03-23-16

In appreciation for the opportunities Caltech afforded him, Professor Mory Gharib along with his wife Shoreh and daughters, Maral and Alma (PhD ’15), have created an endowed fellowship fund to support new generations of Caltech graduate students. “Mory’s story is an inspiration to us all,” says Caltech president Thomas F. Rosenbaum. “Setting the highest scientific standards, searching for technological interventions to better people’s lives, creating community, and serving that community through personal dedication and philanthropy are qualities rarely found in one individual. We are proud to have Mory as a colleague and his family as members of the Caltech family.” [Caltech story]

Seeking a Balanced Equation

03-21-16

Applied Physics graduate student Peter Hung, working with Professor Roukes, is one of the Caltech students featured in a recent E&S article. “In our lab, we shoot molecules of different sizes and shapes at really small mechanical resonators—tiny bridges almost 1,000 times smaller than the width of your hair—and use the change in the resonant frequency (how fast these bridges are vibrating) to reconstruct the shape and mass of the molecules that we’re shooting,” Hung explains.

The students in this year's Mechanical Engineering 72 (ME72) class, a two-term engineering design lab for mechanical engineering majors, designed, built, and operated, under manual and/or autonomous control, robotic vehicles that could compete and withstand the physical rigors of a robot soccer matches played within a 24-ft x 48-ft arena in the Brown Gym. The 2016 winning team was “Blitzkrieg Bots.” [KPCC coverage]
