We’ve talked about the biggest of the big, now let’s focus in on the smallest of the small. Let’s see what’s inside that basic building block of matter: the atom. You probably know the basics, but with ever more powerful particle...
And now we reach the third part of our trilogy on the human exploration and colonization of Mars. Humans will inevitably tire of living underground, and will want to stretch their legs, and fill their lungs with fresh air. One day, we'll contemplate the possibility of reshaping Mars to suit human life. Is it even possible? What technologies would be used, and what's the best we can hope for?

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 the first place. What does wave/particle duality have to do with astronomy? Well, everything, since light is the only way astronomers can see out into the Universe.
Episode 83: Wave Particle Duality
Sometimes, we donâ€™t get to decide what our showâ€™s about. So many threads come together at the same time driving the decision for us. This is one of those situations. Weâ€™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, we obey. Letâ€™s talk about antimatter.

Weâ€™ve been so crazy following our own whims through the universe that weâ€™ve neglected your questions. That ends today. Itâ€™s time to dig deep into our overflowing email box to retrieve the puzzling questions our listeners have sent in.

Weâ€™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 weâ€™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 job of destroying our DNA, giving us radiation sickness, and maybe (hopefully!) turning us into superheroes.
