Ep. 83: Wave Particle Duality

Have you ever heard that photons behave like both a particle and a wave and wondered what that meant? It’s true. Sometimes light acts like a wave, and other times it behaves like a little particle. It’s both. This week we discuss the experiments that demonstrate this, explain how scientists figured it all out in […]

Ep. 74: Antimatter

Sometimes, we don’t get to decide what our show’s about. So many threads come together at the same time driving the decision for us. This is one of those situations. We’ve gotten so many questions from listeners in just the last week about antimatter that our show had just been chosen for it. You command, […]

Ep. 73: Questions Show #8

We’ve been so crazy following our own whims through the universe that we’ve neglected your questions. That ends today. It’s time to dig deep into our overflowing email box to retrieve the puzzling questions our listeners have sent in. Episode 73: Questions Show #8 (16.8MB)

Ep. 72: Cosmic Rays

We’re going to return back to a long series of episodes we like to call: Radiation that Will Turn You Into a Superhero. This time we’re going to look at cosmic rays, which everyone knows made the Fantastic Four. These high-energy particles are streaming from the Sun and even intergalactic space, and do a wonderful […]

Ep. 69: The Large Hadron Collider and the Search for the Higgs-Boson

When it was first developed, the standard model predicted a collection of particles, and thanks to more and more powerful colliders, physicsists have been able to find them all except one: the Higgs-Boson. It’s an important one because it should explain how objects have mass. The European Large Hadron Collider should have the power and […]

Ep. 32: The Search for Neutrinos

Trillions of neutrinos are produced in our Sun through its nuclear reactions. These particles stream out at nearly the speed of light, and pass right through any matter they encounter. In fact, there are billions of them passing through your body right now. Learn how this elusive particle was first theorized and finally discovered.   […]

Ep. 16: Across the Electromagnetic Spectrum

We see the Universe in visible light with our photon detecting eyes. We can feel infrared heat with our photon detecting hands, and we get sunburns with our ultraviolet photon detecting skin (ouch). But there’s a whole spectrum of photons out there, from radio waves to gamma rays that astronomers use to understand the Universe. […]
