Ep. 339: Space Conspiracy Theories

Yes, we actually landed on the Moon. No, aliens didn’t crash land at Roswell. What is it about space exploration that leads to so many conspiracy theories?

Ep. 338: Copernicus

It’s safe to say that the Polish astronomer Nicolaus Copernicus shook up the whole Universe. Well, our understanding of our place in the Universe. It was Copernicus who came up with the heliocentric model, placing the Sun at the center of the Solar System, with the Earth as just another planet.

Ep. 337: Photometry

There's a lot you can learn by just staring at an object, watching how it changes in brightness. This is the technique of photometry, and it has helped astronomers discover variable stars, extrasolar planets, minor planets, supernovae, and much more.

Ep. 336: Units of Measure

How heavy is a kilogram, how long is a second? How warm is a degree? We measure our Universe is so many different ways, using different units of measurement. But how do scientists come up with measurement tools which are purely objective?

Paumanok.

Following up on my recent request for information about Toronto/tkaronto (and my much earlier query about Wampanoag), I have a question arising from this very interesting half-hour talk in which Amy King, Julia Bloch, and Tom Pickard discuss Basil Bunting’s reading of Whitman’s great “Out of the Cradle Endlessly Rocking” (they only play a few […]

More Yoga Mat Hysteria

The “yoga mat chemical” (azodicarbonamide) is the latest food-based fearmongering, thanks to an unscientific petition by the self-described “food babe,” who apparently feels that she is qualified because she is a computer scientist. (Well, it has the word “science” in it.) Unfortunately, the “yoga mat chemical” is an effective meme. Who wants to eat something [...]

Ep. 335:Photoelectric Effect

Pop quiz. How did Einstein win his Nobel prize? Was it for relativity? Nope, Einstein won the Nobel Prize in 1921 for the discovery of the photoelectric effect; how electrons are emitted from atoms when they absorb photons of light. But what is it? Let’s find out.

Ep. 333: When Worlds Collide

Just take a look at the surface of the Moon and you can see it experienced a savage beating in the past. Turns out, the whole Solar System is a cosmic shooting gallery, with stuff crashing into other stuff. It sure sounds violent, but then, we wouldn't be here without it.

Ep. 332: Stellar Collisions

Out here in the Milky Way’s suburbs, stellar collisions are unheard of. But there are places in the galaxy where stars whiz past each other, and collisions can happen. When stars collide, it’s a catastrophic event, and the stellar wreckage is visible half a galaxy away.

My Radio Interview Rises from The Past (the wonders of podcasts)

As I posted last Sunday, I was on ABC local radio (Adelaide 891 AM) with Ashley Walsh starting 11:40 am ACDST. However, I didn't post until AFTER the show, so people who might have been interested missed out (so much for self-promotion).Well, it turns out they recorded the session, and it is up on the Weekends Blog.
