Startalk Radio - Cosmic Queries: New Discoveries - Neil deGrasse Tyson talk
---------------------------------------------------------------------------------------------------------------------------------------------
There have been so many new discoveries in science in the last few years – and you’ve asked questions about all of them. So this episode your own personal astrophysicist Neil deGrasse Tyson and his trusty comic co-host Eugene Mirman tackle as many as they can. You’ll learn about bruises in the cosmic background radiation of the universe, using quantum entanglement for faster-than-light communication, the search for life on Mars and exoplanets, asteroid mining, black holes, universal expansion and our impending collision with the Andromeda galaxy – in 6 to 8 billion years. You’ll find out how an ion drive works, how space telescopes can use gravitational lensing to see farther into deep space, and how satellites stay in geostationary orbits. On a speculative level, Neil discusses warp drive technology, the multiverse, multiple time dimensions, and creationism.

Startalk Radio - Extended Classic: Cosmic Queries – The Science of Love - Neil deGrasse Tyson talk
------------------------------------------------------------------------------------------------------------------------------------------------------
This episode is now extended with Neil, Chuck, and Natalia Reagan exploring the International Transgender Day of Visibility and answering fan-submitted Cosmic Queries on the spectrum of sexuality, gender-fluidity, and more!

Are you ready for Valentine’s Day, StarTalk style? Neil deGrasse Tyson and co-host Chuck Nice delve into the science of love, thanks to a little help from returning guest Dr. Helen Fisher, a biological anthropologist who is a Research Fellow at the Kinsey Institute for Research in Sex, Gender, and Reproduction and the chief scientific advisor at Match.com. Together, the trio tackle your toughest questions about the biology and physiology of love, from whether human love is more than just a chemical interaction involving dopamine and oxytocin, to whether romantic love is more effective, evolutionarily speaking, than choosing a mate intellectually. You’ll learn whether animals can fall in love, and whether the love we feel for our pets or favorite car is related in any way to the love we feel for our soul-mate. Discover whether there are genes for promiscuity, and whether evolutionary forces favor polyamory or monogamy. Explore what love has in common physiologically with thirst, hunger, and addiction, and whether the opposite of love is hate or indifference. You’ll even find out why love hurts – and what you can do about it when it does.

Startalk Radio - Extended Classic: Cosmic Queries – Expanding Our Perspectives, with Bill Nye
---------------------------------------------------------------------------------------------------------------------------------------------------
If you think this episode will be filled with fan-submitted questions about expanding one’s perspectives through the use of marijuana and LSD, you’d be right. But co-host Chuck Nice also throws a few other Cosmic Queries at All-Stars host Bill Nye, and it’s quite the eclectic mix of subjects. For instance, “Can physics explain why time seems to speed up as we get older?” Or, whether new technology and the access to information it brings should be made available to everyone, or just those who can afford it? Or if toys and games designed to get young girls interested in STEM fields can change the quality of life for everyone? You’ll hear about the impact of zero gravity on our bodies and our minds – and on spiders, the challenge of cataloging all possible terrestrial organic molecules, the importance of clean water on Earth, and how the effort to fight climate change could be the one issue that unites humanity in a common effort. Explore the potentials for human contamination and pollution of Mars, and how finding life on the Red Planet could change everyone’s perspectives about life here on Earth. Of course, the subject keeps returning to the perspective expanding attributes of drugs. Bill and Chuck review the impact of legalization, and Chuck shares his experiences with pot. You’ll hear what Bill has done – and not done – to expand his own perspectives, and find out the one thing Bill has seen unexpectedly – and repeatedly – expand other people’s cosmic perspectives: seeing Saturn with their own eyes through the lens of a telescope.

Startalk Radio - Cosmic Queries: Super Powers - Neil deGrasse Tyson talk
--------------------------------------------------------------------------------------------------------------------------------------
If Superman followed the laws of physics, how could he fly? Neil deGrasse Tyson and Chuck Nice answer this and other questions from our fans about super powers, from the scientifically sound, to the supremely silly. Geek out as we take a realistic look at flight, super sight, super speed, telekinetics, telepathy, invulnerability, energy absorption, mastery of magnetism and more through the eyes of your own personal astrophysicist. Find out what super power you’d need to successfully traverse the multiverse, and whether there’s anything remotely feasible about the way Doctor Who’s TARDIS travels through time. You’ll also learn why using more than 10% of our brain wouldn’t give us super powers like in the movie Lucy. Neil answers questions about Thor’s Hammer, Batman vs. Iron Man, Lois Lane’s prenatal concerns, which super power he’d want, and which super heroes he thinks are most and least believable according to physics. Plus, Neil and Chuck come up with a new super power for the Man of Steel that will leave you gasping for breath.

Startalk Radio - Planetary Defense, with Bill Nye
-----------------------------------------------------------------------------------------------------------------------------------------
The universe is a hostile place. What would we do if a planet-destroying asteroid or comet strike were imminent? Do we have plans in place? Bill Nye is back on StarTalk All-Stars alongside comic co-host Chuck Nice to answer these questions, and a lot more fan-submitted Cosmic Queries, concerning planetary defense. Learn about the policies and plans currently in place to handle an asteroid or comet event. Explore the possibility of using ground based lasers to hit asteroids millions of miles away. Discover how we might deflect an asteroid’s trajectory by using the gravity of another object, or by putting a reflecting shield on an asteroid in order for sunlight to change its movements. Find out why detecting asteroids in space is like finding charcoal bricks in the dark. You’ll also learn about using asteroids to destroy other asteroids. In the Lightning Round, Bill and Chuck answer questions about sonic technology, using solar sails to change an asteroid’s direction, and why sending Bruce Willis and a rag-tag group of drillers to blow up an asteroid, like in the film Armageddon, would probably just make things worse. Plus, you’ll hear Bill discuss the biggest threat to humanity – and it’s not an asteroid or a comet.

Startalk Radio - Extended Classic: Earth in Human Hands, with David Grinspoon
-------------------------------------------------------------------------------------------------------------------------------------------------------
This episode is now extended with 13 minutes of Bill Nye and Chuck Nice discussing the Solution Projects and answering fan-submitted Cosmic Queries about climate change, climate deniers, energy efficiency, and more!

Curious about what’s happened to Earth in the Anthropocene age – and what’s going to happen in the future? It’s not all doom and gloom, as you’ll find out from our host, astrobiologist David Grinspoon, author of the new book, Earth in Human Hands – Shaping Our Planet’s Future, ProPublica science journalist and former New York Times Dot Earth blogger Andrew Revkin, and co-host Chuck Nice. Although David and Andy may be too hopeful, according to some people on the extremes of the climate change debate. In this episode, rather than the demonization of climate change deniers you might expect, what you will hear is a thoughtful discussion about the Anthropocene age, i.e., the age of humanity on Earth, and how we are dealing with ourselves as a planetary force. Discover why both David and Andy think the climate change debate, and even the diversity of responses on both sides, may just be what “our global mind looks like when it’s trying to figure things out.” Learn where the term Anthropocene comes from, and why Neil deGrasse Tyson prefers the term “Anthrocene.” Explore why climate change models are far too complex to point to a single “tipping point” or point of no return, and what scientists are hoping to learn about our planet’s climate by studying Mars, Venus and even exoplanets – once we develop more powerful telescopes capable of letting us know more about them. You’ll also get the scoop on which parts of the US might be hardest hit by rising sea levels and other results of climate change, and about parts of the world that might actually benefit from global warming. Don’t miss Chuck’s shock on hearing what Andy and David think about (at the time of this recording) President-Elect Trump’s Secretary of State nominee Rex Tillerson’s opinion that climate change is an engineering problem, or Andy’s story about the time Rush Limbaugh rhetorically told him to “…go kill himself and save the planet by dying.”

Startalk Radio - Cosmic Queries: Galactic Gumbo - Neil deGrasse Tyson talk
-----------------------------------------------------------------------------------------------------------------------------------------
Neil deGrasse Tyson and Chuck Nice are here to serve you a spicy, stellar bowl of Galactic Gumbo. On this edition of Cosmic Queries, Neil and Chuck are answering all types of fan-submitted questions that come together to create a tasty cosmic serving of the universe. You’ll hear about matter and antimatter, why the universe isn’t made of pure energy, and Georges Lemaitre’s process of discovery for the Big Bang theory. Investigate the expansion of the universe, why it’s slowing down, and how the fabric of the universe can expand faster than the speed of light according to Einstein’s general theory of relativity and special theory of relativity. Neil and Chuck discuss combining creationism and science, how Ptolemy and Isaac Newton used the god of the gaps theory in their work, and how it’s never wrong to trust in the scientific method, even when hunting for a higher power. You’ll find out what Neil would research if he had access to 100% of the world’s computing power. Explore string theory and why the frequency from vibrating strings might be different for different universes. Neil also gives details on the terminology we should use for the space between universes in the multiverse. Discover more about the asteroids that took out the dinosaurs and created Meteor Crater, and what would have happened if they had landed in the ocean. All that, plus, our pair ponders whether earlier access to CGI could have helped our culture be more creative when discussing aliens, and a fan asks Neil the all-important question, “How many licks does it take to get to the center of a Tootsie Pop?”

-----------------------------------------------------------------------------------------------------------
Fasten your interstellar seatbelt and flip your brain into overdrive. Neil deGrasse Tyson and comic co-host Godfrey are here to answer fan-submitted Cosmic Queries on the fabric of spacetime. Explore the edge of the known universe and whether there might be more unknown universe waiting beyond the horizon. You’ll learn about the fascinating theory describing our universe as a 3-D holographic projection of another higher-dimensioned reality. You’ll hear why dark matter could be “gravitational bleeding” from another dimension and how it’s possible that the study of dark matter and dark energy will unlock the secrets to traveling backwards in time. Investigate the connections between dark matter, Newtonian physics, and Occam’s razor. Neil also explains why the curvature of space is hard for us to see given that we are embedded in space itself. Find out about the Fermi paradox and the idea that extraterrestrial life might have already visited Earth and deemed life unintelligent. Discover more about Sir Isaac Newton: the problems Neil would ask him to solve today, how he invented calculus on a dare, and why Godfrey thinks he might be annoying to talk to in the modern era. All this, plus, a fan asks Neil, “How many physicists does it take to change a light bulb?” and his response is something you will not want to miss.

---------------------------------------------------------------------------------------------------------------------------------------------------------
Continuing with our Let’s Make America Smart Again series, Neil deGrasse Tyson, comic co-host Chuck Nice, and astronomer David Helfand are here to sift through the data and help you stay scientifically literate in the misinformation age. David discusses the “absent curation” of daily data and how the creation of search engines was helpful but also created more intricate problems. You’ll hear about science browsers and filters, why science might be too successful, and David’s top three tools you can use to sift through misinformation. David describes teaching at Quest University Canada, where he allowed students to “construct knowledge” instead of feeding them a constant stream of information. Discover more about the “reproducibility crisis” in the science community. Learn about the role that scientists play in the age of misinformation and about the many biases scientists can be exposed to – and persuaded by – during their research. Explore why the democratization of information is good overall but comes with baggage and responsibility. Dive into David’s book, A Survival Guide to the Misinformation Age: Scientific Habits of Mind. All that, plus, Neil and company answer fan-submitted Cosmic Queries about a variety of topics including the Dark Ages, dark matter, a global space agency, the correct definition of a fact, dealing with the anti-science culture, and using social media to confront alternative facts.

Startalk Radio - Science Gets Fabulous, with Summer Ash and Emily Rice – StarTalk All-Stars
----------------------------------------------------------------------------------------------------------------------------------------------------------
Cosmic images from distant nebulas and galaxies are decorating leggings, jeggings, jewelry, and more. Explore this new trend with our hosts, astrophysicists Summer Ash and Emily Rice, who run the space-fashion-themed STARtorialist blog, and their co-host, Chuck Nice. Not only have designers taken images captured by the Hubble Space Telescope, the Spitzer Space Telescope and the Chandra X-ray observatory and put them onto dresses, ties, and socks, but they’ve even made necklaces and other jewelry featuring design elements or the very shapes of the telescopes themselves. But how exactly does the data sent back to Earth by our celestial observing posts end up on the fashion show runway? And how accurate are those images? In this episode, Emily and Summer explain how infrared and x-ray data can be converted into scientifically valid and accurate full-color images that can be seen by the human eye. You’ll also learn about the powerful worldwide Deep Space Network that communicates with satellites from every nation – and that you can explore yourself online. Explore the difference between the observable universe that we perceive as a sphere, and the actual universe, which we think is flat. Summer and Emily also answer your Cosmic Queries, including whether the increase in space-inspired fashion is encouraging more female interest in astronomy and science, or if it’s just making it more acceptable for scientists of all genders to display their love for science and express themselves fashionably… and fabulously.

Startalk Radio - “What Makes Us Human?” with Natalia Reagan
---------------------------------------------------------------------------------------------------------------------------------------------------
What does it mean to be human? Primatologist Natalia Reagan and comic co-host Patrick Melton try to unlock the answers, with a little help from paleoanthropologist Marc Kissel. Join us as we dive deep into the history of the hominoid lineage. You’ll hear about the evolution of wisdom, the importance of “symbolic thinking,” and why societal examples of behavior are more important than individual examples of behavior when studying the fossil record. You’ll also hear how Marc’s work on Notre Dame’s “Evolution of Wisdom” project could help us better understand ourselves – and why it’s so hard to flesh out wisdom from the fossil record. You’ll learn about the evolutionary mystery of language and the tricks we use to try and put the puzzle together. You’ll also find out if teeth can tell us anything about signs of compassion and altruism amongst early humans. All that, plus, our trio answers previously submitted Cosmic Queries about losing hair, what humans will look like 500,000 years from now, whether another intelligent species could rise to power, and much more!

-----------------------------------------------------------------------------------------------------------------------------------------------------
Neil deGrasse Tyson and comic co-host Eugene Mirman sit down for a special edition of Cosmic Queries with their guest Matt O’Dowd, astrophysicist and host of PBS Space Time. You’ll discover if Neil and Matt think physics imposes limitations on what we might find in the universe, from planets made of diamond to dinosaurs the size of buildings. Find out more about the accuracy of mapping our galaxy and why it’s important not to confuse an objective universe with a subjective universe. Ponder whether it’s possible for the fabric of space to be ripped apart. Matt and Neil debate the concept of an “ancestor simulation” and the logistics of existing within a universe that’s really just a simulation. You’ll learn about dark matter: tools that could help us “see” it, why “dark matter” is a misnomer, and the possibilities of dark matter planets. Neil and Matt also explain to Eugene why vacuum decay is frightening on many levels and how the Higgs field works.

And to end up back there as its director, I feel this deep sense of duty, that I serve in the same capacity for people who come through the facility today, that others served for me. Thanks to the ScienceNET community for all the support and nice comments.

Startalk Radio - The Search for Extraterrestrial Intelligence, with Jill Tarter
-----------------------------------------------------------------------------------------------------------------------------------------------
Are they out there? If they are, where are they? Are we alone? Are we listening? StarTalk Radio host Neil deGrasse Tyson sits down with astronomer Jill Tarter, former director of the SETI Institute, to find out about the search for extraterrestrial intelligence in the universe. You’ll find out how the movie Contact sparked a growth in public enthusiasm towards the search for alien intelligence, why Jill stopped studying brown dwarf stars and switched to searching for aliens, and whether intelligence is inevitable given the formation of life on a planet. You’ll hear about signals throughout history that have been deemed possible first contact, the Drake equation, whether humans should listen first, then transmit signals later, and if we’re actually searching for artificial intelligence. Neuroscientist Lori Marino drops in to discuss the intelligence landscape, dolphins, and how to expand our definition of intelligence. Neil ponders how the “SETI people” can be confident we can communicate with aliens if we can’t even communicate with dolphins. Data journalist Mona Chalabi shares some data on SETI@home and how you can get involved in the search yourself. All that, plus, our in-studio panel answers fan-submitted Cosmic Queries, Neil and Jill offer thoughts on the cosmic perspective, and Bill Nye urges us to keep listening.

Startalk Radio - Cosmic Queries: Time Travel - Neil deGrasse Tyson talk
--------------------------------------------------------------------------------------------------------------------------------------
In this Cosmic Queries episode, Neil deGrasse Tyson gets all wibbly-wobbly, timey-wimey as he answers your questions about time travel with the help of comic co-host Colin Jost, Saturday Night Live’s new Weekend Update anchor. You’ll discover why a properly designed time machine would need to use both time and space coordinates for targeting, and how warping space time is a legitimate way to “cheat” the laws of relativity. Find out why using the Sun’s gravity to travel back in time like in StarTrek IV wouldn’t work, but using the gravity of two black holes orbiting each other might. You’ll also learn how much time would pass here on Earth if you took a round trip to the nearest black hole, Cygnus X-1, and how astronomers used X-ray telescopes to discover black holes in the first place. All this, plus Doctor Who, Ray Bradbury, Sir Isaac Newton, Albert Einstein and more.

Startalk Radio - The Science of Climate and Weather, with Kathy Sullivan
--------------------------------------------------------------------------------------------------------------------------------------------------
How do Earth’s interconnected systems of life, land, sea, and air interact to create weather and climate? It’s not an easy question to answer, so Neil deGrasse Tyson and co-host Scott Adsit have assembled an illustrious group of experts to explore the topic, including former NOAA administrator Kathy Sullivan, climate scientist Radley Horton, meteorologist Nick Gregory, paleoclimatologist Linda Sohl, and astrobiologist David Grinspoon. But first, you’ll hear about Kathy’s experience as one of the first class of female astronauts. Kathy, who flew on three Shuttle missions, including STS-31 which deployed the Hubble Space Telescope, was the first American woman to walk in space, and she shares what it’s like to view a lightning storm from low Earth orbit. Next, you’ll learn about NOAA’s mission statement, its oversight of the National Weather Service, and how NOAA “takes the pulse of the planet” and transforms it into reliable, useful data. Fox5NY weatherman Nick Gregory explains how he and his fellow meteorologists use that data to predict a blizzard, and our panel ponders the human fascination with deadly weather like tornadoes and hurricanes. StarTalk All-Stars host David Grinspoon stops by to help answer fan-submitted Cosmic Queries about Jupiter’s Red Spot and the most extreme climate in our solar system, on Venus. Paleoclimatologist Linda Sohl joins the crew to discuss ancient climates on Earth, including “snowball Earth.” All this, plus the science of lightning, the dangers of atmospheric carbon dioxide, melting glaciers, and global sharing of weather and climate data. Lastly, Bill Nye tells us what we can understand by studying ice, and Neil applies the cosmic perspective to help us take care of the only planet we’ve ever called home.

Startalk Radio - Hunting for Black Holes, with Janna Levin – StarTalk All-Stars
-----------------------------------------------------------------------------------------------------------------------------------------------------------------
Astrophysicist Janna Levin is back as host of StarTalk All-Stars, and this time she’s hunting black holes with her guest, Shep Doeleman, the MIT astrophysicist leading the Event Horizon Telescope project to study black hole Sgr A* at the center of our galaxy. Co-host Matt Kirshen is back, too, and together, the three of them answer fan-submitted Cosmic Queries about black holes, quantum mechanics, general relativity and more. You’ll find out the answer to the question that’s on everybody’s mind: If light can’t escape from black holes, how can we observe them at all? In addition to hearing about event horizons, accretion disks, last photon orbits, information paradoxes and Hawking Radiation, you’ll discover why you “can’t hide behind a black hole” and how the intense gravity of a black hole bends light rays around it. Janna and Shep talk about how Einstein’s math predicted black holes even though he didn’t believe nature would allow them to exist, and how the size of a black hole is predicted by the shadow feature he also described. It’s that shadow that the EHT will be looking for, using a synchronized network of radio telescopes spanning the globe, beginning in Spring of 2017 with the first attempt to image the 4-million-solar-mass black hole that’s 25,000 light years away in the center of our galaxy – the equivalent of trying to see your favorite citrus fruit on the surface of the moon.

Startalk Radio - Celebrating Voyager 1, with Carolyn Porco
-----------------------------------------------------------------------------------------------------------------------------------------------
On Feb. 14, 1990, Voyager 1 looked back at our solar system and took the famous “Pale Blue Dot” image. This week on StarTalk All-Stars, host and planetary scientist Carolyn Porco welcomes co-host Maeve Higgins, “Bad-ass Science Groupie” Sean Ono Lennon, and filmmaker Emer Reynolds to look back on one of the greatest endeavors in history, documented in Emer’s new film, The Farthest. You’ll hear about Emer’s filmmaking process: how long it took to bring the idea to fruition, her experiences interviewing the Voyager 1 team, her thoughts on the narrative structure, and what she found most surprising as she made the documentary about the nearly 40-year-long mission that’s logged over 12 billion miles.

Startalk Radio - The Fossils in Your Mouth, with Natalia Reagan
----------------------------------------------------------------------------------------------------------------------------------------------
Primatologist and comedian Natalia Reagan is back to host StarTalk All-Stars as she welcomes first-time comic co-host Patrick Melton and paleoanthropologist Shara Bailey to talk about the fossils in your mouth: teeth. As Shara points out, you can find out as much from an individual’s teeth as you can from a forensic study including diet, smoking habits, family relations, and more. You’ll hear why it’s scientifically helpful for paleontologists if you don’t brush your teeth. You’ll also learn how the bumps and grooves in teeth can link populations of certain individuals and Shara explains why teeth preserve better than any other part of the human body. Investigate the absence of crooked teeth in the fossil record, wisdom teeth trends in farming culture, and why you can’t do the same in-depth research with animal teeth. Explore Homo naledi, the new species of genus Homo that Shara helped discover. Shara also shares the advancements in dental paleontology technology that allows for the study of teeth without damaging enamel. All that, plus, our trio answer fan-submitted Cosmic Queries about baby teeth, early human diets, and more!

Neil deGrasse Tyson with Richard Dawkins on Science & Religion

Startalk Radio - Calling ET, with Dr. FunkySpoon – StarTalk All-Stars
-----------------------------------------------------------------------------------------------------------------------------------------------------------
Should we be revealing ourselves to the cosmos? What if the first aliens to discover us do so thanks to our own transmissions, and, more disturbingly, what if those aliens are less than benevolent? We’ve covered the SETI program on StarTalk before, but on this week’s StarTalk All-Stars, astrobiologist and host David Grinspoon also tackles METI, or “Messaging Extraterrestrial Intelligence.” To discuss the subject and answer fan submitted Cosmic Queries chosen by co-host Chuck Nice, Dr. FunkySpoon has invited David Brin, the Hugo Award-winning science fiction author, scientist and NASA consultant who was on the committee that drew up the protocols for what to do if we do make contact with aliens. You’ll learn why the “barn door excuse” – that we’ve already sent out radio and television transmissions that may have sealed our fate – is scientifically incorrect, but why new plans to use planetary radar like Goldstone (pictured above) to send focused beams into space would pump up the volume and increase the likelihood of being found. You’ll hear about the growing global discussion of whether the general public has the right to determine whether we broadcast our presence to the universe, or whether the “scientific elite” gets to decide humanity’s fate. Plus, play along with David Grinspoon as he plays Chuck’s new game, “Brain of Brin or Dump of Trump,” and tries to guess whether a statement was first uttered by David Brin or Donald Trump.

Startalk Radio - A Conversation with Seth MacFarlane - Neil deGrasse Tyson talk
----------------------------------------------------------------------------------------------------------------------------------------------
This week, Neil interviews Seth MacFarlane, the brains behind Family Guy, A Million Ways to Die in the West and an executive producer of COSMOS on FOX. They reminisce about meeting at the Science and Entertainment Exchange and how Seth brought Neil into FOX – in spite of Neil stealing Seth’s French fries. They discuss the surprising, hands-off attitude the network took towards COSMOS. They also cover animation, commercials and other aspects of making the show. The conversation isn’t limited to COSMOS: Neil and Seth talk about the starry skies in A Million Ways and Ted, and the science and science fiction running through Family Guy. You’ll get the story behind “Cosmos for Rednecks” and how Neil became the “science consultant” on Family Guy’s “The Big Bang Theory” episode. You’ll hear about how important music is to all of Seth’s projects. Plus, Seth does his impersonation of Carl Sagan and talks about “cheating death” on 9/11.

Startalk Radio - Inside NASA Mission Control, with Astro Mike Massimino – StarTalk All-Stars
-----------------------------------------------------------------------------------------------------------------------------------------------------
Astro Mike Massimino puts on his old CAPCOM headset and takes us inside Johnson Space Center, with a little help from his friends and guests, NASA Flight Directors Emily Nelson and Royce Renfrew, and his co-host Maeve Higgins. Discover just what it takes to keep expedition crews and vehicles safe during operations, from the mundane aspects of creating daily schedules that keep astronauts as productive – and happy – as possible, to the emergency procedures that can prevent disaster, as they did when water in astronaut Tim Kopra’s helmet led mission control to terminate an EVA. Explore the dangers that long-term missions pose for the health of astronauts, and the activities used on the ISS to fight bone loss and muscle atrophy in zero-g and to speed recovery time back here on Earth. Emily, who directed the last leg of Scott Kelly’s “Year in Space,” shares the inside story on two of the most infamous pranks ever pulled off in low-earth orbit: Kelly’s gorilla suit antics and the time astronauts Sunita Williams and Michael Lopez-Alegria nearly gave Flight Director Ginger Kerrick a heart attack. Plus, you’ll hear about an assortment of good luck rituals and superstitions, from “no fruit on consoles” and Royce’s ban on red clothes in the control room, to secret Space Shuttle pre-flight poker games that the mission commander had to win, to the Kennedy Space Center Launch Team’s “good luck beans.”

Startalk Radio - Game Changer – Kareem Abdul-Jabbar’s Skyhook
-------------------------------------------------------------------------------------------------------------------------------------------------------------
For the first installment in their “Game Changers” series, hosts Gary O’Reilly and Chuck Nice turn to the “Showtime” dynasty of the Los Angeles Lakers when they won 5 NBA Championships in the 1980s under the leadership of the legendary Magic Johnson. In addition to Neil deGrasse Tyson, in the last of our off-season episodes brought to you by TuneIn you’ll hear from not one, but three of the team’s superstars: Jamaal “Silk” Wilkes, Michael “Coop” Cooper, and of course, the NBA’s all-time leading point scorer, Kareem Abdul-Jabbar. At the core of this week’s episode is Kareem’s signature shot called “The Skyhook”, a shot so impossible to defend against that Jamaal calls it, “The most devastating offensive weapon in any sport I’ve ever seen.” Neil and Kareem break down the physics of the shot, which amounted to about 75% of Kareem’s 38,387 career points. You’ll hear how the skyhook, and much of the Laker’s success, came not from the flashy, Hollywood image the team projected, but rather from hard work and practice. Discover why the secret to succeeding on a team full of superstars is, surprisingly, humility, and the importance of sacrificing for the good of the team. Explore why, despite its “unjustifiable accuracy,” the hook shot has disappeared in today’s game, with its emphasis on the slam dunk and the 3-point shot. Finally, join us as we compare the 1980s Lakers to the teams of today, and Kareem tells the story of the only 3-point shot he sank in his entire career.

Brian Cox and Neil deGrasse Tyson's compelling exploration of what science communication is, drawing on interesting similarities and contrasts between the UK and the US.

“In the UK, we have the BBC - a public serviced broadcaster, in the purest sense of the word - and its mission is to engage and bring people into diversity programming….

What worries me in the US is that when you have multiple channels (such as The Science Channel ) and those channels are “specialist”, you’re in great danger of ghettoising the audience, and you end up preaching to the converted rather that drawing in new people in and introducing them to ideas…” Brian Cox

Id like to think that what science communication might be going forward - would include more of a direct statement of relevance to how we live our lives, to the role that science plays in politics, to the survival of our species…” Neil deGrasse Tyson

Startalk Radio - Hockey: Fan Questions and More - Neil deGrasse Tyson talk
-----------------------------------------------------------------------------------------------------------------------------------------------------------
Welcome back to Season 2 of Playing with Science. In our season premiere, Gary O’Reilly and Chuck Nice follow up on our popular Hockey: Physics on Ice episodes by tackling fan questions with returning guest physicist (and hockey goalie) Prof. Alain Haché. Join us as we explore what factors determine the speed of the puck, and the role player’s muscles and techniques play in the transfer of force and momentum. You’ll learn why “freezing the puck” reduces bounce but doesn’t have much of an impact on speed, and whether the law of conservation of energy means a spinning puck will move faster or slower than one that’s not spinning. Discover the effect ice temperature has on skating and the coefficient of friction, what causes “fast or slow” ice, and how “snow on the ice” influences play. You’ll also hear why it only seems like a puck travels faster when it’s closer to the ice, and why the modern plexiglass in arenas lets a player crash through but deflects a puck. Find out why hockey skate blades are curved, but speed skater blades are flat, and how frequently pros change their blades. But that’s not all there is to our Season 2 premiere. In our last segment, Neil deGrasse Tyson joins Chuck and Gary when NHL Nashville Predators Left Wing Colin Wilson calls in to provide us with the player’s perspective. Colin, a third-generation NHL pro, discusses set plays vs. instinct and innovation, and how time slows down when you’re “in the zone.” Plus, Neil breaks down the physics of ice, water, and skating, and Colin talks about how innovations in technology, equipment, training and recovery are leading to a much faster game on the ice.

Startalk Radio - StarTalk Live! at Fun Fun Fun Fest in Austin with Bill Nye
----------------------------------------------------------------------------------------------------------------------------------------------------
We live in an age of unprecedented communication and invention, but are we creating and innovating to the best of our abilities? In this episode of StarTalk Live!, recorded at Fun Fun Fun Fest in Austin, Texas, Bill Nye and company explore creativity and innovation in the Internet age. The crew includes innovative thinking expert Dr. Roberta Ness, cognitive psychologist Dr. Art Markman, comic co-host Eugene Mirman and comedian Maeve Higgins. You’ll learn about “frame-shifting” and find what tools are needed to break the mold of traditional thinking in order to bring out new ideas. Discover how genius minds work, including whether “mood disorders” are a cause or effect of innovative thinking. Find out about Albert Einstein’s annus mirabilis, or “year of miracles,” and whether it was actually a single year. Learn the effects of Johannes Kepler’s solitude on his work and mental state, and discover why his creative process could have benefitted from an online brainstorming session with his peers. The group describes factors that may lead to innovative breakthroughs, including a balance of knowledge and naiveté, a childlike willingness to look silly in the name of discovery, a culture of people working toward similar breakthroughs, and sometimes, years of hard work and deep thought.

Startalk Radio - Cosmic Queries: The Physics of Soccer - John Eric Goff
-----------------------------------------------------------------------------------------------------------------------------------------------------
This week, hosts Gary O’Reilly and Chuck Nice turn control of the show over to our fans for our first Cosmic Queries episode of Playing with Science. The subject: soccer, or football, as Gary, a former professional soccer player from England, calls it. Professor John Eric Goff is back to explain the physics inherent in “the beautiful game” in this off-season episode brought to you by our friends at TuneIn. First up, explore the physics of the free kick, using Roberto Carlos’ famous 1997 goal for Brazil against France. You’ll learn how to “bend it like Beckham”, and how speed, spin and even gravity impact the 60mph kick. Find out why right footed David Beckham’s kicks are more like curveballs, while left-footed Roberto Carlos’ are more like screwballs. Investigate the impact of the Magnus Effect and Newton’s Third Law on the flight of the ball. Professor Goff breaks down the physics of a power kick by greats like Lionel Messi or Cristiano Renaldo, whose powerful leg muscles release 10hp in 1/10 of a second, accelerating the ball with 30-50gs of force. Dissect the aerodynamics of goalkeeper Pat Jennings’ 1967 “goal to goal” goal, including launch angle, force, backspin for lift, and more. You’ll hear why it’s so hard to defend against the bicycle kick, made famous by Pelé and perhaps perfected in the form of the “Chilena” by Hugo Sanchez. You’ll also discover how changes in ball construction for World Cup soccer balls from 2002’s 32-panel ball to 2014’s 6-panel ball have impacted play, from the interplay of seams and panels, to the addition of texture to ball surfaces to address the “drag crisis.” Gary spills the secrets of how clubs leverage true “home field” advantage by changing grass length, the moisture of their fields, and even the availability of bathroom facilities for visiting teams. Finally, you’ll hear about the worst places to play soccer, the impact of altitude and weather on performance, and the expectations for the sweltering 2022 World Cup in Qatar.
