You've got 10 minutes with Einstein. What do you talk about? Black holes? Time travel?

Why not gambling? The Art of War? Contemporary parenting?

Each week, host Jason Gots surprises some of the world's brightest minds with ideas they're not at all prepared to discuss. Join us and special guests Neil Gaiman, Alan Alda, Salman Rushdie, Margaret Atwood, Richard Dawkins, Maria Popova, Mary-Louise Parker, Neil deGrasse Tyson and many more...

NASA astronomer Michelle Thaller on ​the multiple dimensions of space and human sexuality

Science and the squishiness of the human mind. The joys of wearing whatever the hell you want, and so much more.

This morning on the way to the school bus, my almost 11 year old son was explaining to me that if you shrunk an elephant down to the size of a mouse, it would shiver, then die, because of its slow mitochondria, due to something called the Rule of Squared Threes, which he also proceeded to explain. Then he explained something about neutron stars, claiming that they are essentially a giant atom, which I don't think is actually true. Then he started on another topic and I explained that this was all very wonderful but that I had learned all the science my brain could hold at 7:15 am.*

Sadly, my own journey as a scientist ended in high school biology, when I put the dissected tail of a fetal pig on a toothpick and said "Hors d'oeuvres?" to several classmates, which earned me an F for the project. But happily, there are people like my guest today, Astronomer Michelle Thaller, and my son Emre, who are excellent at explaining scientific wonders to dummkopfs like myself. Michelle is—let me take a deep breath here—the Assistant Director of Science for Communications at the NASA Goddard Space Flight Center. And her inspiring perspective on science and humanity—which she shares in her TV shows and her podcast Orbital Path—makes me wish that biology teacher had had a better sense of humor.

*Note: Emre learned much of this from this very interesting YouTube channel

3D printing might save your life one day. It's transforming medicine and health care.

What can 3D printing do for medicine? The "sky is the limit," says Northwell Health researcher Dr. Todd Goldstein.

  • Medical professionals are currently using 3D printers to create prosthetics and patient-specific organ models that doctors can use to prepare for surgery.
  • Eventually, scientists hope to print patient-specific organs that can be transplanted safely into the human body.
  • Northwell Health, New York State's largest health care provider, is pioneering 3D printing in medicine in three key ways.

Extraordinary machines – with neuroscientist Susan Hockfield

Convergence 2.0: Engineers are using the "natural genius" of biological systems to produce extraordinary machines—self-assembling batteries, cancer-detecting nanoparticles, super-efficient water filters made from proteins found in blood cells. Neuroscientist and MIT President Emerita Susan Hockfield and host Jason Gots discuss what all this could mean for our future.

Think Again Podcasts
  • "One of my tools as president was never to talk about change. People hate change. But at MIT no one could deny you the opportunity to do an experiment."
  • "If we can create these spaces for convening around our most important problems, We can make progress much faster than we can by insisting that people do the work on their own. And that's the power of the university at its best."

Adam Gopnik on the rhinoceros of liberalism vs. the unicorns of everything else

Torn between absolutism on the left and the right, classical liberalism—with its core values of compassion and incremental progress whereby the once-radical becomes the mainstream—is in need of a good defense. And Adam Gopnik is its lawyer.

Jared Diamond (historian) – Look inward, Nation

Personal crises and national crises have more than a few things in common. From Brexit to the partisan divide in America to Germany after World War II, Jared Diamond talks with host Jason Gots about how we get through them (or don't).

Think Again Podcasts
  • Nations that blame their problems on other nations (or particular groups) don't recover so well from crises.
  • The US is consuming at 32x the rate of most African countries. Even if Africa didn't exist, it would be unsustainable.
  • What Jared Diamond has learned about human nature from his neighborhood association.
