5/15/18 Show feat. Paleontologist Evan Saitta

Featured image credit: Smithsonian

In this show Stevie spoke with paleontologist Evan Saitta, expert on dinosaurs and fossilization. We discuss dinosaurs broadly, as well as what what we know, how we know it, and what are the really difficult questions. Stevie also learns how Jurassic Park lied to her, and how we know some dinosaurs have feathers. Towards the end of the conversation, Evan discusses his fascinating work actually making fossils in the lab!

5/1/18 WPRB Pledge Show feat. Sam Wang on Gerrymandering in NJ and the Scientific Study of Elections

This was WPRB’s 2018 pledge drive!! Brian and Stevie started out the show with science news – ancient sloth hunts uncovered and a study shows that freedivers from Southeast Asia evolved to have bigger spleens. Then Professor Sam Wang, founder of the Princeton Election Consortium and co-host of the Politics and Polls podcast, joined Stevie on the mic to discuss gerrymandering in the US and specifically in New Jersey and Pennsylvania. Then we get in to the more general topic of the scientific study of elections.

Additionally, you’ll hear Brian and Stevie talk past shows and why they love WPRB.

4/17/18 Show feat. Philosophy Professor Adam Elga on Decisions, Risk, and Cascading Failures

Science news and events started out the show. 45 minutes in, Professor Adam Elga came on the mic to speak on some thought problems in philosophy that are pertinent to his research. For instance we start with the problem of contingency: how concerned should we be that much of what we believe is contingent on, for example, the circumstances of our birth?

We then build up the conversation to his current research on cascading failures – this is when systems that depend on each other fail in a kind of domino effect. Think the 2008 Financial Crisis. This gets us in to topics like the Tragedy of the Commons, the Prisoners’ Dilemma, and his (and his collaborator Daniel Oppenheimer’s) new concept of Risk Pollution.

More information on the topics we discussed in the show, provided by Adam Elga:

4/3/18 Show feat. Matt Weinberg on Algorithms, Incentives, and Game Theory

Trouble with the Mixcloud embed? The live show can be found here.

Science news and events started out the show. Brian spoke on new research on concussions and Stevie on the Chinese space station that fell to Earth recently. 45 minutes in, Professor Matt Weinberg came on the mic to speak on his work as a theoretical computer scientist. He researches mechanism design – these are algorithms that take user incentives in to account. He considers human decision making and economics to design algorithms to guide the user to interact with the algorithm in the optimal way. He uses the example of online dating, ad auctions on sites like Facebook and Google, and cryptocurrencies.

2/27/18 Show feat. Aaron Wolf on Neanderthal Genomes and Us

This show had tons of great science news and an excellent discussion with Aaron Wolf, doctoral researcher on neanderthal genomes and specifically how neanderthal and modern human genomes mixed (i.e. they reproduced) in ancient times. To begin, Aaron walks us through what we know about neanderthals and our modern misconceptions of them, and how they came about. From there, he discusses how the neanderthal genome was mapped, and why we think that most living humans have about 2% neanderthal DNA — and what that DNA is for.

This week on These Vibes, Stevie discussed research with fellow observational cosmologist, Eve Vavagiakis. Eve is a researcher on the Atacama Cosmology Telescope, aka ACT, located in the Atacama desert in Chile. She discusses cosmology and astrophysics, her research and how she makes her measurements, and answers excellent listener questions.

12/5/17 Show feat. Kieran Bhatia on Hurricane Forecasting and Preparedness & Norbert Cruz-Lebron on the current situation in Puerto Rico

Kieran Bhatia models hurricanes to improve forecasting techniques in the program for Atmospheric and Oceanic Sciences here at Princeton University. In this episode, he tells us how hurricanes are forecasted, why it’s so difficult and common misconceptions about hurricanes. We discuss this year’s hurricane season and what it does (or does not) say about climate change.

In the last segment, Kieran tells us about how we can prepare ourselves better for hurricanes (NOAA site), his organization Canes on Canes in Florida, which aimed to educate on the science of hurricanes and hurricane preparedness.

Early in the episode, Norbert J. Cruz-Lebron, graduate student in neuroscience and member of the Princeton SACNAS Chapter, jumped on the mic to tell us about the current state of affairs in Puerto Rico after Hurricane Maria. Additionally, he tells us about his own experience being in the US while the rest of his family was at their home in PR when the hurricane hit, and shares testimonials from friends and family. (Hopefully he’ll be back on the show next year to tell us about his graduate research!)

You can support the Princeton Society for Advancement of Chicanos/Hispanics and Native Americans in Science at @PrincetonSACNAS on Venmo.All donations will go to the Puerto Rico Recovery Fund managed by the Center for a New Economy (CNE) Group, an independent, non-partisan think-tank that advocates for the development of a new economy for Puerto Rico.

11/28/17 Show feat. Steven Gubser and Frans Pretorius on Black Holes and their “Little Book” of them

In this installment of These Vibes, Stevie speaks with Princeton University physics professors Steven Gubser and Frans Pretorius on their recently released Little Book of Black Holes (Princeton University Press, 2017). The discussion begins where the book ends, at the Epilogue, where the authors read their “Letter to Einstein.” From there we dive in to the definition and formation of black holes, and where they exist in our universe. Professors Gubser and Pretorius tell us about the experimental verification of these weird astrophysical things and answer listener questions like what would happen if a black hole entered our solar system? would we notice? Listen in and check out the book!

In the very beginning of the show, regular guest and science historian Ingrid Ockert joined us to review the stunning new documentary Jane (trailer), about the life and work of Jane Goodall, featuring much unseen footage from her younger years and research. For further reading she recommends Primates and Me, Jane.

11/14/17 Show feat. the Prototype G Team on Robotics!

In this episode of These Vibes, Stevie welcomes three members of the Prototype G girls’ robotics team to tell us about their work together on robotics. They get in to the details of how they build their robots and why! This is the Princeton, NJ area team, but there are groups all around the country. If you’re interested in joining them or starting a team in your area, check out their site!

2017/11/07 Show feat. Sam Wang on Gerrymandering: Past, Present, and What to do About the Future

Featured image from a cartoon mocking the shape of a Massachusetts gerrymandered district.

In this episode of These Vibes, Professor Sam Wang visited the studio. He’s founder of the Princeton Election Consortium blog, co-host of WooCast’s Politics & Polls, and professor of molecular biology and neuroscience. We discuss his expertise in gerrymandering — what it is, how it came to be such an issue, the current state in elections and the Supreme Court, and what is and can be done to remedy our system.
