Welcome to the weekly round-up of stories I wrote this week, wherever they hide.
- A tour of physics, Angry Birds style (Double X Science): The odds are good that you’ve played Angry Birds, even if (like me) you don’t own a device that will run the game. My colleague Rhett Allain wrote a book for kids, using Angry Birds as an invitation to learn quite a bit about physics, from particle trajectories to cosmology. I reviewed the book for Double X Science.
- My book-in-progress, Back Roads, Dark Skies, hit a major snag, and its future is unclear. Based on the responses I’ve received, I will not be able to find a publisher without changing the book in an essential way, so I’m feeling a little stuck. So, to show myself (if nobody else) that I’ve accomplished something in the 18 months I’ve been working on the book, I published two excerpts from Chapter 2: Of Bosons and Bison at Galileo’s Pendulum.
- Microcosmos: My tour of the DZero detector at Fermilab, with a digression on my favorite New Yorker cartoonist.
- Naming the animals in the particle zoo: The hows and whys of particle detection, in the context of the Tevatron at Fermilab. This excerpt also includes what may be my best joke yet, if I can say that about my own writing.
- The Milky Way’s black hole, like Cookie Monster, loses more than it eats (Ars Technica): Astronomers have known for many years that our galaxy harbors a supermassive black hole. Yet, it’s a very quiet black hole: the material surrounding it emits very little light compared to other galactic nuclei. A new X-ray observation may hold the key: only about 1 percent of all the material swirling around the black hole is captured, making it a Cookie Monster-level messy eater. (And yes, I’m proud of combining Cookie Monster and black holes in one article.)
- This doesn’t count as my writing, but I’m joining a number of friends and colleagues at GeekGirlCon in late October for some do-it-yourself science! Well, I’m going if I can afford it; you can help with that by donating to our cause. We’ve already raised more than $400, so I’ve begun photographing myself around the city wearing my Cthulhu hat. If you give us more money, we’ll do even more embarrassing things. You can’t lose.
- Atmospheric science in a bolt of lightning (Galileo’s Pendulum): Lightning is powerful enough to split molecules into their constituent atoms, and strip electrons away. For a brief moment, lightning can heat air to 30,000° C, more than 5 times the surface temperature of the Sun. An astrophotographer took an amazing snapshot of a lightning flash, with a twist: he used a diffraction grating to split the light into its component colors. The result is that we can identify some of the chemical components of air produced when the molecules and atoms were blasted by the powerful electric discharge.
This week also marked both my parents’ birthdays. Happy birthday, Mom (Monday) and Dad (Friday)!
