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!

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.

In this Halloween show, we examine a question fundamental to science: what is rigorous enough to be real science? Pseudoscience, or fringe science, is difficult to pin down and sometimes yields revelations in scientific understanding. However, in its worst forms it misleads and distracts from real discovery. Learn from Ingrid Ockert how “In Search Of” became a hit show in the 60s and 70s to Carl Sagan’s chagrin, and how the Princeton Engineering Anomalies Research Laboratory studied the influence of minds over matter on the Princeton campus for 28 years. All this closes with musings adapted from Princeton’s Michael Gordin, and a discussion on how fringe science only exists as a shadow of the scientific enterprise.

In this episode of These Vibes, Stevie welcomed Dr. Yoni Kahn in to the studio to discuss his work as a phenomenologist and theoretical particle physicist. He’s the kind of theorist that works closely with data, coming up with experiments to test new physical laws. Specifically, his focus is on the Standard Model of particle physics — our current best theory for all the fundamental particles in the universe. But, we know that there’s more to discover! In this interview, Yoni talks us through the history and details of the Standard Model, as well as hints of things beyond, like the search for dark matter.

This time on These Vibes, we welcome Dr. Jason McSheene, PhD from Princeton University’s Department of Molecular Biology and professional medical writer. Jason walks us through the insanity that is embryonic development: how does a growing bundle of cells know to grow organs? How does it turn various proto-organs into a spleen, kidneys, a heart? It all has to do with fluid flow and protein growth, a subject Jason mastered during his PhD work at Princeton. After this, we talk about Jason’s communicative side, and how he has transitioned into the medical industry as a disseminator of diabetes information. How do you keep physicians, researchers, and pharmaceutical companies on the same page? It’s all in the episode!
In this episode of These Vibes, Brian subbed in for Stevie (sick and sounded like a screecher monkey) spoke with our resident science historian Ingrid Ockert on her recent article, “Science Television in the Sputnik Age.” Additionally, we welcomed Dr. Julio Herrera-Estrada back on the show to discuss his in-depth research on droughts in North America. All that, and lots of music.

In this show, we zoom in on the science of ice core drilling. Scientists have long examined the layers of ice sheets, which are about two miles thick over Greenland; different summer ices and winter snows make yearly trends visible to researchers, so that we can track the climate over the last 100,000 years. How do researchers manage to camp out in the harsh Greenland tundra for months at a time to dig up miles of ice core? What do we learn about the tumultuous climate from this venture? Much of the discussion is based on an excellent book, The Two-Mile Time Machine by Richard B. Alley.

Biodiversity is enormous in the rainforest compared to the polar climes, and scientists are just starting to understand why. It may have to do with seasonality and competition within a species.
In this episode of These Vibes, Stevie spoke with Dave Seal, a mission planner on the Cassini space probe which spent many years orbiting Saturn. Cassini operated its final maneuver, called the “Grand Finale,” and ended its observing by plunging in to Saturn just last Friday morning at 8am EST. It took a final image and took it’s last bits of data on Saturn’s atmosphere before being destroyed. Listen in to learn about the mission, its development, goals, and discoveries, and learn more about what it’s like to be a mission planner on a NASA space probe.
All that plus great music, and science news from microplastics in our seasalt to the new research on cancer cells.

This week, we host Robert Nazarian, graduate student in Atmospheric and Oceanic Sciences, to talk through his research on ocean dynamics and internal waves. How complicated is the motion of the sea, and how can this massive system be modeled? Rob’s research focuses on energy flows through the sea, where waves carry heat from one place to another. How do ocean flows, large-scale motion and small-scale turbulence alike, affect the environment in and out of the water? Further, Rob will talk about his outreach, and how he has used innovative teaching techniques to engage students in learning about oceanography.
In this edition of These Vibes, Professor Edward Felten joined us back in the studio to discuss electronic voting — what that means, what are the alternatives, the pros and cons, and the current state of voting technology in the US. Edward Felten is professor of computer science and public affairs here at Princeton University, and founding director of the Princeton Center for Information Policy. Additionally, he was Chief Technologist for the Federal Trade Commission from 2011-2015 and joined the Obama administration as Deputy US Chief Technology Officer in 2015.
Our discussion gives particular attention to usability issues with the current voting computers used in US elections and their vulnerability to attacks. Professor Felten discusses the role of hacking in the 2016 election, and, to wrap-up, what the ideal voting system would be, using our current technology.
