Whittaker and Ben Reimold. As a student of policy at the Woodrow Wilson School, Julianne co-founded the Amal Foundation for investing in the education of Syrian students. Through this effort and others, Julianne and Ben have learned to funnel Princeton student efforts into aiding those stuck in refugee camps. What geopolitical movements have led to the current refugee crisis? How do the displaced function in their new communities? Hear how Ben and Julianne encountered the refugee crisis in the Middle East, and what they are doing now to connect uprooted students with new education opportunities. If you’re curious how students here are fighting for refugee rights both domestically and abroad, then listen in to this interview!

The last twenty minutes of the show is my own glorification of a field-defining book, The Death and Life of Great American Cities by Jane Jacobs. It’s a pleasure and an obligation to read if you’re curious about the structure of cities, architected from the ground up.
The moons of Jupiter are a solar system in miniature, rocked with energy from Jupiter’s own enormous mass. All 67 objects in orbit (that we know of!) have unique features: some are volcanic, some frozen over, and some could support life given some terraforming.
As usual, the playlist can be found on WPRB.com or below.

Very unfortunately, the show tonight was not recorded due to technical difficulties at WPRB. Sorry about that!
Today we hone in on climate change by talking with Dr. Stephen Pacala of Princeton’s Department of Ecology and Evolutionary Biology. Dr. Pacala’s new class on the Environmental Nexus investigates the worldwide interplay between agriculture, biodiversity, and climate, so we’ll speak about how these systems feed into each other. What do our coupled studies of the market and worldwide climate tell us about enacting environmental policies today? As Dr. Pacala informs us, we have the technology today to avoid many of the worst consequences of increased carbon dioxide in the atmosphere–it’s only a matter of doing the hard work of applying this technology to our agriculture, electricity grid, and so on. As he claims, humanity is trending towards solving these problems, present politics in the US aside.
Further, we spoke at length about how scientists quantify the impact of climate change. How can we know whether fossil fuel emissions are really at fault for causing the death of the Great Barrier Reef, or for the recent flooding of Louisiana? Scientists can now pinpoint the change in risk of extreme weather due to human-introduced pollution, and the results are startling. Even more, we can now say that humans have caused instances of climate change in Africa, which in turn have made conflicts more likely. Studies like this rely on statistical methods, which they use to show impressively disastrous links between pollution and human life.
Before Dr. Pacala joined us, I brought on former guest Dr. Paul Gauthier to talk about the interplay between plants and our atmosphere. Can more carbon dioxide help plants grow? Is faster food always better? And above all, how do we manage a growing population with a food supply in danger?

Tonight, we’re finally airing the entirety of The Science of Memory, the live show that we put on with the Council of Science and Technology in February. We brought Mike Lemonick (Scientific American editor) and Sabine Kastner (Princeton neuroscientist) on stage to discuss the science of memory, amnesia, and how our brains learn. You’ll hear how Lonni Sue Johnson, a Princeton artist and airplane pilot, lost her ability to form new memories, and how her personality is intact despite being lost in the present. Alongside the science, the Princeton Laptop Orchestra played three original pieces, from an extended version of our theme song to one that translates neuron signals into noise. We had so much fun putting this show together for a live studio audience, so we hope you’ll enjoy the full performance broadcast!
In addition to the recording, we start off the show with science events and:
In today’s packed show, we start off fifteen minutes in with regular guest and History of Science expert Ingrid Ockert. Her review of Peter Kuznick’s Beyond the Laboratory covered scientists-turned-activists from the 1930s, who rose to protest the corporate causes of the Great Depression and the growth of Nazi Germany.
Next, 45 minutes in, we welcome Jill Knapp, Professor of Astrophysics and co-founder of the Princeton Teaching Initiative. Jill tells her story as an advocate for New Jersey inmates, and how she leads a cohort of volunteers that design curricula and teach college courses in local prisons. Eventually, we turn to the overarching issues: how can education help break the cycle of mass incarceration in America?
Kaz also investigates the computerization of plant growth, building trees of all ages into simulations used for long-term climate studies. Are there overarching rules that regulate how plants grow larger and taller, and can we codify them into mathematics that make botanical sense? Writing these into a model would allow us to understand why trees are different shapes and have different behaviors.
The interview starts 45 minutes into the show, but the introduction has science events, English Beat tickets, and more.

Carnivorous plants have a curious evolutionary history: they get nitrogen and phosphorus from the insects they eat, a trait which evolved separately many times.
In Nepal, farmers knew that snow leopards and Himalayan wolves were eating livestock, but no one knew it made up a quarter of their diets. Until now.
February 11th was the International Day for Women and Girls in Science; incidentally, Maryam Mirzakhani recently won the first Fields Medal to go to a woman for her work on Riemann surfaces.
Featured image: A photo from the Atlanta Constitution, showing three National Guardsmen defending six black prisoners, whose tale forms the core of Blood at the Root (Patrick’s research began with this photo).
This week’s show starts with Drew University professor and author Patrick Phillips, taking a deep look at his new book Blood at the Root. The novel covers the expulsion of all black residents from Forsyth County, Georgia, which began in violence in 1912 and lasted up through the 1980s. In his expansive historical research, Patrick talks with the descendants of whites and blacks who participated in the evictions, and his book analyzes the deep societal divide that still hangs over modern America. How did this twisted series of events happen, and what can its still-lingering consequences tell us about race in the USA?
Otherwise, the show features exclusively Islamic music, and shares science news (from Saturn to pond goop in Washington) and local science events as always.
In today’s show we speak with doctoral researcher Mallika Randeria on her work in the Yazdani lab at Princeton University. As she explains in the interview, her research
explores the quantum behavior of electrons in a magnetic field. In fact, she uses a powerful scanning-tunneling microscope to actually image the electrons! Last year her group became the first to ever accomplished this and they got some astounding and (almost) unexpected results! Tune in to the show if you want to learn about the weird quantum behavior of electrons and what they actually look like up close when they’re exhibiting quantum effects, how a scanning-tunneling microscope works (and about the one here at Princeton), and some of Mallika’s other research imagining the phenomenon of superconductivity.
Featured image: Wind turbines mess with air flow, but the process can only be modeled in sophisticated labs or in computer codes like this Purdue University software.
We welcome Mark Miller, a PhD candidate in Prof. Hultmark’s Gas Dynamics Lab, who knows all about the aerodynamics of wind turbines. Wind energy is a crucial component of the future’s energy landscape, but learning how to optimize their engineering is a work in progress. How should a windmill farm be laid out to maximize each turbine’s output? How can scientists model the air flow around windmills in lab-sized models? And finally, how does wind energy fit into the grid?

This week features Jacob Schwartz, a PhD candidate in plasma physics here at Princeton, who brings us a deep concern: what should we do with our nuclear waste? Fission plants produce radioactive byproducts over time, and these concoctions will be dangerous to life for millennia. At the WIPP facility in New Mexico, scientists are testing many methods for safe storage of radioactive materials. Even more intriguingly, reports from WIPP contemplate strategies for warding off future civilizations, communicating across the centuries that an area is unhealthy to inhabit. How can we send messages on the timescales of the pyramids? How far do duty or ethics push us to confine our nuclear waste?
