How Rocky Planets Form – Konstantin Batygin

caltech 2023-01-12 | A new theory for how rocky planets form could explain the origin of so-called "super-Earths"—a class of exoplanets a few times more massive than the Earth that are the most abundant type of planet in the galaxy.

Further, it could explain why super-Earths within a single planetary system often wind up looking strangely similar in size, as though each system were only capable of producing a single kind of planet.

"As our observations of exoplanets have grown over the past decade, it has become clear that the standard theory of planet formation needs to be revised, starting with the fundamentals. We need a theory that can simultaneously explain the formation of the terrestrial planets in our solar system as well as the origins of self-similar systems of super-Earths, many of which appear rocky in composition," says Caltech professor of planetary science Konstantin Batygin (MS '10, PhD '12), who collaborated with Alessandro Morbidelli of the Observatoire de la Côte d'Azur in France on the new theory. A paper explaining their work was published by Nature Astronomy on Jan. 12.

Shaking in Our Seats: Earthquake Science on the Big Screen (full event)

caltech 2023-01-03 | When it comes to accuracy in earthquake movies, Caltech professor of mechanical and civil engineering Domniki Asimaki observed, “The better the special effects get, the worse the movie gets.” Asimaki was part of a panel of researchers and public officials, moderated by seismologist Lucy Jones, that celebrated 100 years of Caltech’s Seismological Laboratory through a special event examining the science behind onscreen earthquakes.

Shaking in Our Seats: Earthquake Science on the Big Screen, was presented by the Caltech Science Exchange and the Lucy Jones Center for Science and Society on November 12, 2022. More than 450 people joined to watch clips—ranging from the absurd to the surprisingly accurate—from the films Earthquake and San Andreas and the TV movie The Great Los Angeles Earthquake. The experts discussed which scenes showed what could really happen during and after a major earthquake, which were movie madness, and what to do when the next one hits.

Native Americans Name Asteroid Aylóchaxnim or Venus Girl

caltech 2022-11-30 | On June 7, at Caltech's Palomar Observatory in the forested mountain outside San Diego, members of the Pauma band of indigenous peoples gathered to celebrate the naming of the first known asteroid to circle entirely within the orbit of Venus. The asteroid was originally discovered in 2020 by the Zwicky Transient Facility, or ZTF, which operates at the Palomar Observatory. Sometime after its discovery, the ZTF team decided to ask the Pauma band, whose ancestral lands include the mountainous region where the observatory is located, if they would like to bestow the new cosmic find with a name of their choosing.

Ultimately, the indigenous group chose to name the asteroid 'Ayló'chaxnim, which means "Venus girl" in their native language of Luiseño.

The Palomar naming ceremony included blessings, traditional Pauma songs, and a reading of a poem titled Luiseño Songs of the Seasons, which describes how "it will soon be time for the acorns to fall from the trees" when "Venus is rising."

Caltech Science Exchange: What Is AI?

caltech 2022-09-12 | Artificial intelligence is transforming scientific research as well as everyday life from communications to transportation to health care and more. In this video, learn about the history of AI and what it means for our world.

The field of artificial intelligence arose from the idea that machines might be able to think like humans do. It required the analysis of how our brains process information and use it to perform new tasks and adapt to novel situations. Continuing exploration of these concepts has fueled technological innovation and led to the development of artificial intelligence applications that use data to identify patterns, carry outpredictions,and make decisions. Often these applications are more efficient and precise than humans are — sometimes replacing people to perform repetitive or tedious tasks and calculations.Today, rapid advances in the field have opened new avenues for research and discovery but also raise ethical and safety questions.

Professor of Theoretical Physics Kathryn Zurek and Professor of Physics Rana Adhikari talk about one of the biggest mysteries in physics today: quantum gravity.

Quantum gravity refers to a set of theories attempting to unify the microscopic world of quantum physics with the macroscopic world of gravity and space itself. Zurek, a theorist, and Adhikari, an experimentalist, have teamed up with others to design a new table-top-size experiment with the potential to detect signatures of quantum gravity.

In conversation with Caltech science writer Whitney Clavin, the scientists explain that at the microscopic, or quantum, level, matter and energy are made up of discrete components; in other words, quantized. Many scientists believe that gravity is also quantized: If you magnify space itself enough, you should see discrete components. In this webinar, Zurek and Adhikari discuss why measuring quantum gravity is so difficult and how they plan to go about searching for its elusive signatures.

caltech 2022-06-28 | As part of the Caltech seminar series Contextualizing Engineering & Applied Science: History, Ethics, and Identity in STEM, alumnus Edray Goins gave this in-person, simulcast presentation on 5/16/22.

On November 7, 1968, the student paper "California Tech" exclaimed the headline "Girls Coming to Tech!". In less than a year, the Board of Trustees had gone from ordering that a study be conducted on admitting women as undergraduates to the Institute to actually approving a proposal. But 1968 would prove to be more tumultuous for the Institute than the vote to change the makeup of its undergraduate population.

In January 1968, the Caltech YMCA (later named the Caltech Y) made a bold and controversial decision to place Caltech students face-to-face with institutional racism. It ran a program called "the City and the Ghetto" which brought 20 undergraduates to live and work with Black families in Pasadena's northwest side for three days. In April 1968, Martin Luther King was assassinated; there were complaints that the only acknowledgement from the Institute was flying the flag at half-mast for just one day. In Febrary 1968, Junior and ASCIT President Joseph Rhodes was selected for a second term. Two months later, Rhodes wrote a controversial editorial for the "California Tech" where he questioned the myth of the superiority of a Caltech education due to the disregard
of the larger societal upheavals. Just two weeks after that, a petition to recall Rhodes as president of ASCIT was circulated. Perhaps most striking about all of this: Rhodes was Caltech's only Black undergraduate at the time.

In this presentation, we follow the events at the California Institute of Technology from 1968 through the lens of the "California Tech."

Edray Herbert Goins is Professor of Mathematics at Pomona College. He has worked as a researcher at both Harvard and the National Security Agency, and has taught at both Caltech and Purdue. Professor Goins has published over 25 journal articles in areas such as applied mathematics, graph theory, number theory, and representation theory, and on topics such as Diophantine equations, elliptic curves, and African Americans in mathematics. He has given more than 220 invited addresses on his research, acted as a referee for nearly 20 different journals in mathematics, served on dozens of panels for the National Science Foundation (NSF), and been awarded more than $1,370,000 in external funding. Goins currently runs a federally-funded Research Experience for Undergrads (REU) titled PRiME: Pomona Research in Mathematics Experience (PRiME).

Goins is a Caltech alum; he graduated in 1994 with majors in Mathematics and Physics. As an undergraduate, Goins conducted independent research, under the tutelage of history professor Douglas Flamming, on the history of the Black students at Caltech. This work was presented in the student publication, the California Tech, in a series of ten articles published during the Winter Term of the 1993-1994 academic year. The history department awarded Dr. Goins the Rodman Paul prize in 1994.

Caltech Energy 10 — Bob Weisenmiller, California’s Innovative Climate/Energy Policies — 6/14/2022

caltech 2022-06-27 | Caltech Energy 10 (CE10) brings together key leaders in engineering, science, industry and government to provide a wide audience with information, data, and inspiration on why and how to reach a 50% reduction in the emission of global warming gases (GWG) within the decade. The energy ecosystem is highly complex, technically and socially, and the path for meeting this goal remains ill-defined. The solution will require fundamental changes in electricity generation, transportation, and commercial, industrial, and residential energy consumption. Join us for a deep dive into what the foremost leaders in this sphere are thinking.

The CE10 Public Program, a series of live-streamed talks on June 14 and 15, 2022, was organized by the Division of Engineering & Applied Science (EAS) at Caltech with our partners Stanford University, 4-Good Ventures, and the Resnick Sustainability Institute.
