Particles of Thought

Pluto Is a Planet. So Is the Moon.

Particles of Thought

Show Notes

Hakeem has hot takes on space. For instance, the moon is a planet.

In Hakeem’s new book, Why Do We Exist?, he shares big ideas about the universe. Why do so many stars come in pairs? How likely is extraterrestrial life? What if there was no friction? Hakeem challenges us to think like him and see our reality through his Nine Realms of the Universe. Through that lens, atoms model galaxies, stars take new names, and the statistically improbable becomes more likely over time. Settle in for a conversation between Hakeem’s mind and the heavens.

Guest Bio: Hakeem Oluseyi is host of Particles of Thought, an astrophysicist, author, STEM educator, multi-patented inventor, science journalist, TV personality, science communicator, and inspirational speaker. His research is based on “hacking stars” to understand our universe better and develop innovative new technologies. Oluseyi’s work has resulted in 11 patents and more than 100 publications covering contributions to astrophysics, cosmology, and plasma physics and the development of space missions, observatories, focal plane instruments, detectors, semiconductor manufacturing, and ion propulsion.

Our host flips the interview and shares his humble beginnings before science superstardom. Hakeem opens up about a childhood moving between some of America's toughest neighborhoods, surviving drugs, and overcoming addiction. Luckily, an encyclopedia article on Einstein changed everything and set him on his unlikely path from rural Mississippi to Stanford. Along the way, he changed his name, found some key mentors, and became an astrophysicist, but more importantly, Hakeem started a journey to bring science to millions Learn more about NOVA and visit our YouTube channel. -------------------------- Guest Bio: Hakeem Oluseyi is host of Particles of Thought, an astrophysicist, author, STEM educator, multi-patented inventor, science journalist, TV personality, science communicator, and inspirational speaker.

Earthquakes can be more powerful than atomic bombs. Luckily, Harvard geophysicist John Shaw has ideas on how to beat them. What really causes earthquakes? How can cities and buildings be engineered to survive them? John and Hakeem trace the science of shaking ground from ancient myth to cutting-edge machine learning, and reveal just how much is still left to discover deep beneath the surface.

Dudley Professor of Structural and Economic Geology at Harvard University, where he also serves as Vice Provost for Research. A structural geologist and applied geophysicist, he studies the faults deep beneath our feet, with research spanning earthquake hazards, energy systems, and carbon storage.

We can cause earthquakes. Geophysicist John Shaw joins Hakeem to reveal how humans have been triggering earthquakes for decades, and in some cases, it’s on purpose. John explains how an experiment 50 years ago turned earthquakes on and off and clarifies all the confusion around the process of fracking. It's a surprising look at how understanding human-triggered quakes might be the key to predicting natural ones.

We can’t predict earthquakes, but we can beat them. Geophysicist breaks down what actually keeps people alive when the ground starts shaking. From flexible buildings to early warning systems, John walks Hakeem through what separates cities that survive major earthquakes from cities devastated by them, and why the difference often comes down to policy not physics.

Big earthquakes can change the Earth’s rotation. And Harvard geophysicist John Shaw says these giant events can teach us a lot. He traces our understanding from ancient myths to modern studies and unpacks what;s really going on beneath the surface. John reveals why a magnitude 7 earthquake releases 30 times the energy of a WWII-era atomic bomb, how the largest quakes make the Earth ring like a bell for days, and why the deadliest earthquake in history wasn't even the biggest one.
