RockClocks & Supernovae – May 27
Wonderfest Science Envoys are early-career researchers with enhanced communication skills and aspirations. Following short talks on provocative modern science topics, these two Science Envoys will answer questions with insight and enthusiasm:
• UC Berkeley geophysicist Caroline Hasler on Measuring Geologic Time with Rock Clocks — In microscopically small crystals within rocks, radioactive elements decay at predictable rates and function as tiny clocks. These “rock clocks” help us to figure out the timing of major events in Earth history — from the moment of Earth’s formation to the asteroid impact that killed the dinosaurs.
• UC Berkeley astronomer Eli Wiston on Seeing Core-collapse Supernovae with Radio Telescopes — At the end of its life, a massive star will contract and explode in spectacular fashion, outshining the light of an entire galaxy. While most astronomers focus on the optical light given off by these stellar explosions, there is a wealth of new information to be gained by observing invisible wavelengths. With radio telescopes, we can study new aspects of supernovae: their stars’ activity in the years before death, their environments, and what they leave behind after the explosion fades.

Elements & Fairness – Apr 28
Wonderfest Science Envoys are early-career researchers with enhanced communication skills and aspirations. Following short talks on provocative modern science topics, these two Science Envoys will answer questions with insight and enthusiasm:
• UC Berkeley astronomer Natalie LeBaron on Origins of the Elements — From the oxygen we breathe to the gold in our jewelry and the calcium in our bones, most periodic table elements are forged by stars. How does the universe transforms simple hydrogen into the rich diversity of atoms that build planets, life, and everything we see around us? Beginning their lives in vast clouds of gas and ending in massive explosions, every star in the night sky creates and scatters ingredients for new worlds.
• UC Berkeley psychologist Colin Jacobs on Children’s Sense of Fairness — Our motivation to enact fairness shapes human behavior across societal and individual levels: from outrage at economic inequalities, to personal protest against not being considered in a discussion. As parents and teachers know, our motivation to insist upon fairness starts early, often through shouts of “that’s not fair,” or very strict regulation of turn-taking. What motivates children to object to unfairness, and how does this moral impulse develop throughout early childhood?

Quantum Gravity – July 29
By allowing space and time to bend, Einstein’s theory of gravity, General Relativity, explains how apples fall, how planets move, how the universe expands, and how black holes form. Quantum Mechanics, on the other hand, describes subatomic physics — in a very different language that seems incompatible with General Relativity. Yet, unlike any other classical theory in physics, General Relativity “knows” about Quantum Mechanics. Einstein’s theory allows us to compute how many quantum states a black hole has, and how much quantum information fits in the universe. Somewhat like an oracle, it has revealed to us profound properties of quantum theory that have since been rigorously proven. Amazingly, gravity encodes quantum information using sophisticated tools that are central to emerging quantum technologies.
Our Wonderfest speaker is Raphael Bousso, Professor of Physics at UC Berkeley. Dr. Bousso leads the Bousso Group at the Berkeley Center for Theoretical Physics.

Natural Physics – June 10
Basic physics shapes the natural world. Through evolution, creatures have figured out how to use the laws of physics to make biology flourish. Flamingos generate water vortices to trap food. Various birds and fish use vortex shedding and fluid turbulence to control movement. For small animals, electrostatic forces and/or capillary forces can reign over gravity to affect the critters’ very survival. Nature is a beautiful dance of biology and physics.
Our speaker is biophysicist Victor M. Ortega Jiménez, Assistant Professor in the Integrative Biology Department at UC Berkeley. Dr. Ortega-Jiménez directs Cal’s Ornithopterus laboratory in organismal dynamics.

Consciousness & Physics – May ??
When philosopher Thomas Nagel asked, “What is it like to be a bat?”, he was not asking about what it’s like for a human to be a bat — not the experience of, say, Batman. Nagel was vivifying the so-called “hard problem of consciousness”: What is it like for a bat to be a bat? More broadly, what is the nature of a bat’s — or of any — subjective experience? How does brain activity (from a third-person objective point of view) become a first-person feeling (from a subjective point of view)? Perhaps the “relativity” principles of Galileo and Einstein can help us understand this seemingly profound distinction between the first-person point of view (my experience) and the third-person point of view (another’s brain activity) as recognized by neuroscience.
Our speaker, physicist Nir Lahav, is a postdoctoral researcher in the Consciousness and Cognition Lab at Cambridge University. Dr. Lahav has developed what he and philosopher Zachariah Neemeh call A Relativistic Theory of Consciousness.

Kilonova Metals & Cat Ecology – Apr 29
Wonderfest Science Envoys are early-career researchers with enhanced communication skills and aspirations. Following short talks on provocative modern science topics, these two Science Envoys will answer questions with insight and enthusiasm:
• UC Berkeley astrophysicist Daniel Brethauer on Astronomically Rocking Out to Heavy Metals — The gold in jewelry, the uranium in a nuclear power plant, the caesium in atomic clocks: what do these all have in common? It turns out they were likely forged in the fires of a cosmic explosion known as a kilonova. These extremely energetic events reveal the origins of the periodic table’s heaviest elements.
• UC Berkeley ecologist Tyus Williams on Unraveling the Ecology of Domestic Cats — What if one of our greatest companions is potentially one of our greatest threats? When free to roam, domestic cats can severely disrupt wildlife communities. However, understanding cats’ behavior and how they’re influenced by their surroundings can allow us to develop better conservation strategies.

Eye Movements & Tiny Galaxies – Apr 15
Wonderfest Science Envoys are early-career researchers with enhanced communication skills and aspirations. Following short talks on provocative modern science topics, these two Science Envoys will answer questions with insight and enthusiasm:
• UC Berkeley neuroscientist Stephanie Reeves on The Horizontal Saccade Bias — Humans make eye movements to explore the visual environment. One type of involuntary eye movement, termed a saccade, occurs 2-3 times per second and is one of the fastest movements that the human body can make. New research challenges previous assumptions about how and why saccades arise.
• Stanford astrophysicist Viraj Manwadkar on Tiny Galaxies and Big Cosmic Mysteries — The very smallest galaxies shed light on fundamental questions in physics and astronomy: They play an intriguing role in the formation of cosmic ecosystems, and they even inform our attempt to understand dark matter, the utterly mysterious stuff that constitutes 80% of the material universe.

Black Holes; Kelp Forests – Feb 24
Wonderfest Science Envoys are early-career researchers with special communication skills and aspirations. Following short talks on provocative modern science topics, these two Science Envoys will answer questions with insight and enthusiasm:
• UC Berkeley astrophysicist Natasha Abrams on Black Holes: Discovering the Invisible — Black holes are among the most extreme objects in the universe. They push the boundaries of our knowledge, holding many unsolved mysteries. This talk will explore black holes from “small” to enormous, including how to detect these invisible marvels. In the process, we will probe the very frontiers of astrophysics.
• Stanford marine biologist Will Johnson on The Structure of Kelp Forests — Kelp forests constitute one of the most diverse ecosystems on Earth, and they’re hidden right beneath the waves of our coastline. To research how these ecosystems function, we need to study what lives there. Come learn how scientific diving and modern genetics are helping us unravel the complex structure of kelp forests.

Most Famous Equation – Aug 13
Around the world, people recognize that E=mc^2 oozes cosmic insight. But what does this “most famous equation” really say? What are energy and mass? And what makes the speed of light, c, so important? [Hint: mass, moving at speed c, doesn’t turn into energy!] Using little more than common experience and middle-school math, Einstein’s “special relativity” gem can come to life — with surprising insights into the nature of reality.
Our speaker is long-time physics teacher Tucker Hiatt, founding director of Wonderfest. Tucker has been a Visiting Scholar in the Stanford Chemistry Department, and is a recipient of the Amgen Award for Science Teaching Excellence.

Scavengers+DarkMatter+Biomolecules – Jul 16
Wonderfest Science Envoys are early-career researchers with special communication skills and aspirations. Following short talks on provocative modern science topics, these three Science Envoys will answer questions with insight and enthusiasm:
• Stanford ecologist Chinmay Sonawane on How Scavenging Animals Protect Human Health — Wildlife is rapidly disappearing globally. But why should we care? The loss of scavengers (consumers of already-dead animals) provides an intriguing example of how biodiversity loss has had, and will continue to have, profound consequences for human health.
• UC Berkeley physicist Bethany Suter on Direct Detection of Dark Matter — Ubiquitous, yet deeply mysterious, dark matter constitutes 85%(!) of the material universe. What do we know — and not know — of elusive dark matter particles? Novel laboratory materials may allow us to detect dark matter directly, shining light into the pervasive cosmic shadows.
• Stanford biophysicist Sean Waterton on Making Biomolecules from Electricity — Solar panels produce ever-more clean electricity. At the same time, human activity produces copious amounts of CO2. Modern research in synthetic biology allows us to use electricty and CO2 to create valuable molecules like fats and proteins — and, hopefully, more specialized molecules like medications.

Finding the Wild – May 23
Naturalist Craig Foster has explored and studied some of Earth’s wildest environments. He has also experienced the demands of professional life in our big cities — experiences that might tend to deaden a capacity to appreciate natural beauty. Foster’s latest book, Amphibious Soul: Finding the Wild in a Tame World, vividly addresses the challenge of staying open to the wonders of nature. Of the book, Jane Goodall wrote, “[It] will transform how we think about being human … [and] inspire hope.” In this Commonwealth Club conversation, Foster will help us understand how to attend to earthly beauty and deepen our love for all living things.
Craig Foster is one of Earth’s leading nature filmmakers. Foster’s My Octopus Teacher won the 2021 Academy Award for Best Documentary. We can participate in this Commonwealth+Wonderfest event either in person or online.
Quanta and Fields – May 14
Arguably, quantum field theory (QFT) presents humanity’s deepest insights into the rules of reality, i.e., into the laws of existence. QFT allows us to describe — with remarkable accuracy — the particles and forces that animate the cosmos, including the stuff of mind and body. Note that calling QFT a theory pays the highest scientific compliment: QFT has vast scope, and QFT is supported by an extraordinary amount of evidence.
Wonderfest and the Commonwealth Club present physicist Sean Carroll to discuss key ideas in his latest book, The Biggest Ideas In the Universe: Quanta and Fields. As in his first Biggest Ideas book (Space, Time, and Motion), Dr. Carroll goes beyond analogies to show how physicists really think about nature’s underlying principles.

Communication; Growth – Apr 30
Wonderfest Science Envoys are early-career researchers with special communication skills and aspirations. Following short talks on provocative modern science topics, these two Science Envoys will answer questions with insight and enthusiasm:
• UC Berkeley psychologist Sophia Li on Imperfect Communication — As a communicator, I want to transfer information from my mind into the minds of listeners. Research shows that both listeners and uninvolved observers have overly positive perceptions of any communicator. They believe that the communicator knows more than s/he actually does, and has articulated thoughts better than s/he actually has.
• Stanford physicist Josh Tong on Growth and Form — Living creatures grow and transform their shape, to the awe of many scientists. What does it mean to grow? How do we compare an organism at different stages of its growth? Mathematics can help us find the way to understand this fundamental transformation.
