We always say that the Universe is trying to kill you, but we thought we’d really hammer the point home. Dr. Phil Plait from Bad Astronomy joins Fraser Cain for a very special episode of Astronomy Cast. Join us as we hammer out all the ways the Universe wants you dead.
Pamela has a day job, remember? As an astronomer? Recently the 45th Lunar and Planetary Science Conference occurred in the The Woodlands, Texas. Pamela and guest astronomer Sondy Springmann will let us know about the big announcements made at this year's conference.
This week’s blog is about the fun we have had singing together, learning songs chosen from the undiscovered riches of the Library’s music holdings. We have explored the hidden depths […]
1. What happens when you conduct a census of the Mexican educational system? 2. Monopsony in motion, MP3 file, a song by the Anarchist Econometricians of A. What do you know about them? And Felix Salmon on Wonkonomics. 3. Can robots solve the Malaysian mystery? 4. Do poverty traps really exist? 5. An early history […]
When the United States helped defeat Germany at the end of World War II, they acquired the German rocket scientist Wernher von Braun. He had already developed the German V2 rocket program, and went on to design all the major hardware of the US rocket program. This week, we talk about von Braun’s life and accomplishments.
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? We’ll try to get to the bottom of these conspiracy theories, poke holes in their ridiculous ideas and help you build your baloney detection kit.
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.
What a week! I’m still on a book launch buzz, before I can get back to “normal”, if there is such a thing for someone constantly travelling. And now that the book stuff is finally winding down, I can start focusing on what’s next onShow More Summary
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.
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?
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 […]
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 [...]
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.
The Oxford Dictionary of National Biography podcast doesn’t have an exciting format—it consists of professional readings of O.D.N.B. entries. But the podcast producers obviously like picking out quirky subjects to share with listeners. Show More Summary
Around this time last year a space rock crashed into the Earth above Chelyabinsk, Russia. It brightened the skies for hundreds of kilometers, broke windows and injured many people. Let’s look back at the event. What happened, and what did we learn?
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.
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.
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.

Lost in the stacks bills itself as “the one-and-only research-library rock’n’ roll radio show”. Every Friday, they broadcast a one-hour show on WREK Atlanta, where they chat about research-library issues and play tenuously relevant songs. Show More Summary
