An Update After Several Years

Dear fans and followers of These Vibes Are Too Cosmic:

It is wonderful to see continued engagement with our content on this site! I am looking over our posts several years later, having seen so much about our politics, health, and science change since this blog was last updated in mid 2019. The show in its former interview-heavy form had to peter out as Stevie and I turned towards finishing experiments, writing papers, and graduating. Fortunately, we both completed our PhDs over subsequent years and have since moved on to various life ventures.

For one, I need to update you on me: though you may have known me differently, I’m Frances, a physicist at the Princeton Plasma Physics Lab (PPPL) and still as avid a science communicator as I have the bandwidth to be. The more I come out to the world as trans, the more important it is to connect the dots in every venue — so now my new name is connected to this website and a body of work I have loved producing. Nothing is changing about my intention to produce more science on the radio.

That being said, TVR2C has not gone away, though its form has changed substantially! Over the summers of 2021 and 2022, I led a weekly (later bi-weekly) WPRB program under this name, These Vibes Are Too Cosmic, which left out interviews with scientists but distributed many science news stories over the span of the show. Rewarding as this format has become, I would hope that future work brings back talking with real scientists (not just my voice!) and that I have time to come back summer after summer to WPRB 103.3 FM.

Stevie has made plenty of totally unique strides herself, pushing the world forward in her own way. She has changed fields from physics to AI ethics and tech policy. Currently, she is a Senior Ethics Research Scientist at Deepmind. Somehow or another, we’ll both be involved in any future directions These Vibes takes.

Thank you all for your continued listening, feedback, and support!

Our guest this week is the luminous Prof. Jo Dunkley of Princeton’s Departments of Physics and Astrophysical Sciences, who just published her first book, Our Universe: An Astronomer’s Guide. Jo boils down our universe’s 13 billion year history into a digestible story, traveling from planets to stars to clumps of dark matter on the way. She reminds us of the painstaking research that enables our modern understanding: for example, female “computers” like Henrietta Swan Leavitt in the early 20th century made crucial discoveries about stars and distance even as male scientists monopolized the telescopes. Finally, Jo explains the radical idea of measuring gravity by looking at distortions in the cosmic microwave background, a primary thrust of her current research.

8/27/19 Show feat. Mihir Kshirsagar on the Big Issues in Technology Policy

This is a three hour episode. The first hour is music only. One hour in, TVR2C regular programming begins and the interview with Mr. Kshirsagar begins at about 1 hour and 30 minutes in.

In this show Stevie speaks with technology policy expert Mihir Kshirsagar. Mihir is the technology policy lead at Princeton University’s Center for Information Technology Policy and formerly was Assistant Attorney General of New York and was in the AG’s Bureau of Internet & Technology as the lead trial counsel.

Mihir and Stevie speak about the biggest issues in technology policy including big data and data security, as well as some of its history, and the role that both governments and tech companies have to play. Here’s some of the topics:

  • Antitrust in tech — what is “antitrust” and why is it an issue in tech right now
  • Mihir explains his biggest concerns in technology policy today as:
    • Generally, the rise of big data. There’s always been data, but the ability to parse massive amounts of data and make meaningful decisions off of it is unprecedented.
    • Data security and privacy
    • Platforms/intermediaries (middlemen) in tech, specifically the requirement to communicate or access the internet through an intermediary such as Facebook or Google, vs direct connection
  • In the final part of the interview, Mihir discusses his recommendations for the typical consumer of news about tech companies and emerging technology. Essentially, don’t let it scare you! And don’t let anyone convince you that it doesn’t concern you. It does! These companies and tech are ubiquitous, and changing the landscape of communication and access to information and services, to name just a few.

7/23/19 Show feat. Dr. Haider Warraich on the State of the Heart and Dr. Ingrid Ockert on Mooniversary

Today we speak with Dr. Haider Warraich, cardiologist starting at Brigham and Women’s Hospital and Harvard Medical School, on his new book, State of the Heart. As a medical professional and writer, Haider knows firsthand the power of stories to stick in human memory; but he also knows how little the average person understands their hardest-working organ. His book brings the heart, its ailments, and its medical history to life. Though it continually pumps blood through your body, it took humans millennia to understand how the heart works, and medical mysteries still abound. Hear about blood pressure, heart attacks, stress and anxiety, and the future of cardiovascular technology.

Plus, a great intro on the 50th anniversary of the moon landing with Dr. Ingrid Ockert of the Science History Institute, including a massive rocket display on the Washington Monument and a review of the glorious archival film, Apollo 11.

This week, we host Prof. Robert Vanderbei of Princeton’s Department of Operations Research and Financial Engineering (also this summer’s Scientist in Residence at the Princeton Public Library!), expert on telescope design and hobbyist in (among many things) astrophotography. Robert has a passion for digging into the unusual, finding ways to prove to himself how the world works. With astrophotography, he uses telescopes and high-quality cameras to measure distances in space and sometimes discover surprises like variable stars—but he is careful to mention that you can measure an amazing amount even with the right sunset photo. Even down here on Earth, Robert explains how he verified that “local warming” is occurring right alongside global climate change, as demonstrated via years of weather station data you can download yourself.

Today, Kelsey Ockert from the Princeton Public Library brings us Secrets from the Eating Lab by Traci Mann, PhD. It’s a book full of science about nutrition, hunger, and dieting that often flies in the face of “conventional wisdom” (on a topic where opinions abound!). Traci advocates for an easing up on the stress around dieting: it doesn’t usually work for humans to clamp down into strict routines, since our willpower is limited. Listen for a message of body-positivity, appetite and social pressures as backed up by laboratory data!

This week, Scott Andrews of Lawrence Livermore National Laboratory and Titan Labs joins us to share his work on developing superfast cameras for scientific measurements. If your camera is too slow, the event you’re trying to see is too blurry to understand—and tracking the motions of atoms occurring in quadrillionths of a second is hard with any present-day technology. Scott is developing improvements to streak cameras, which convert light into electrons in order to measure events on the picosecond or femtosecond time scale. Hear how he does it, plus the benefits of thinking through design from different perspectives.

Joining us this time is Dr. J. Nathan Matias, Assistant Professor at Cornell University and former Associate Research Scholar at Princeton’s Center for Information Technology Policy. Nathan focuses on the intersection of sociology, psychology and the internet, examining issues like online behavior, harassment, and the shaping of modern discourse by websites and their design choices. We talk through his research on Reddit’s /r/science subreddit, where Nathan and the site moderators encouraged welcoming behavior by including a small rule reminder for commenters. Plus: under the obligation to experiment, websites that manage what we see online ought to do tests to see how their choices affect our experience, and make their results public — taking the tools they use to make effective advertising and deploying them in our interest!

This week we host Margaret Koval, former broadcast news producer and current Princeton Communications Director of Special Projects. Initially a staffer on Capitol Hill with an academic interest in Soviet affairs, Margaret transitioned to broadcast news, cutting tape herself and traveling widely. Eventually she sought longer-form stories, producing documentary films on the World Wars, ancient Rome and more. Here at Princeton, she leads the She Roars podcast, interviewing women alumni from Nobel laureates to community activists, and is planning to start a solution-oriented podcast on climate change.

Before the interview, listen for a Wayfinding book giveaway: Thanks to those that called in and offered their methods of navigation! We heard about getting around with landmarks, compasses, white canes, light pollution, and by memory association.

This week, author Maura O’Connor guides us through her new book Wayfinding: The Science and Mystery of How Humans Navigate the World. Our modern selves may rely on GPS to get from A to B, but our brains are capable of extreme navigational feats: Inuits in snow, Aboriginal Australians in the bush, and seafarers in Oceania all travel far without the concept of “being lost.” Maura shares how these travelers use natural clues and cultural context to find their way, and how neuroscience shows that wayfinding, memory and storytelling are all intertwined.
