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.
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!)
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 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.
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.
In this episode of These Vibes, Stevie speaks with neuroscientist Christa Baker about fruit fly mating songs and electric fish — and for each, how she is tracking their neural pathways to learn how their brains undergo the complicated process communication.
Additionally, animal behaviorist Matt Grobis comes on the air to talk about the nitty gritty “devil’s chess match” of doing research — the good and the bad.
In this show Stevie interviewed Cameron Ellis, cognitive neuroscience researcher at Princeton University. In the first part of the discussion Cameron explained the different theories of what is/isn’t conscious. Are animals conscious? Light switches? The Internet? How do we know that anything is conscious outside of our own selves?
In part 2, they discussed sensory substitution – this is new, fascinating research showing that we can use our current senses to detect new information, like magnetic fields, and our brain will integrate this in to its neural pathways. This research is extremely promising, and seems likely to be of great importance towards goals of, say, helping a blind person “see.”
In the last section, Cameron answers some great listener questions and delves in to the topic of uploading our consciousness in to computers. Is it still us?
This is the third time Cameron has visited These Vibes. The first and second interviews took place last year, and were all about the scientific and philosophical study, as well as history, of consciousness. These shows are not necessary as pre-requisites to the today’s show, but they are excellent additions. Highly recommend.
A chill show — just music and science news. Unfortunately we were switched to webstream-only about 40 minutes in (for a lacrosse game), and neglected to record the rest of the show. Still! Here’s the science news we discussed. Enjoy:

In the primary segment of the show, Stevie spoke with Princeton graduate researcher in classics and host of the podcast Ancient Greece Declassified, Lantern Jack (pseudonym), came on the show to discuss ancient cosmologies. Lantern Jack began with ancient Greece, where the geocentric model reigned and where we have the best, early models of the universe (that we know of).
We discussed geocentric and heliocentric models, how the first calculations of the size and distance to the Moon and the Sun were made, and mused about whether there were or weren’t lenses available.
Then, towards the end of the show Lantern Jack told us a bit about the Antikythera mechanism – believed to be an early analogue computer and actually physical cosmological model, recovered from a shipwreck in 1901.
