Seeing Exoplanets Sideways
Posted by Chad Orzel on November 24, 2010 Given that I’m currently working on a book about relativity, I’m spending a lot of time idly thinking about various relativistic effects. Many of these won’t end up in the final book, but they’re fun to think about. One thing that occurred to be earlier, while thinking about something else entirely, is the Doppler shift.…
The Astrophysics of Bedtime Stories
Posted by Chad Orzel on October 12, 2010 SteelyKid is a big fan of the classic children’s book Goodnight Moon, which, if you haven’t spent the last sixty-odd years in a cave, you probably know features a bunny saying goodnight to a variety of objects in a great, green room. The attentive toddler will find a lot to look at in the pictures–…
Why I’m Skeptical About the Changing Fine-Structure Constant
Posted by Chad Orzel on September 14, 2010 Not long ago, a new preprint on the fine structure constant got a bunch of press, nicely summed up by the Knight Science Journalism Tracker last week. I meant to say something about this last week, but what with it being the first week of classes and all, I didn’t find the time. I still…
Bad Universe, No Biscuit
Posted by Chad Orzel on August 31, 2010 Sunday was a really long day around Chateau Steelypips, and I couldn’t see staying awake to watch the premiere of Phil Plait’s Bad Universe on the Discovery Channel, so I’m way late in writing about it. I DVRed it, though, and watched it last night. The theme of the premiere/ pilot was killer rocks from…
The Science Mindset List
Posted by Chad Orzel on August 20, 2010 It’s nearly time for classes to resume, which means it’s time for a zillion stories about Beloit College’s annual Kids These Days List, listing off a bunch of things that this year’s entering college class, who were mostly born in 1992, have always taken for granted. A sample: 1. Few in the class know how…
Not Everything Is About CO_2
Posted by Chad Orzel on July 24, 2010 Climate change is a major crisis, don’t get me wrong, and it’s something that needs to be discussed extensively in both scientific and policy circles. We’re pumping carbon dioxide into the atmosphere at rather too high a rate, and getting something done about that is a key priority. It’s possible, though, to take the obsession…
Sex, Intuition, and Evidence in Science
Posted by Chad Orzel on July 22, 2010 Over at A Most Curious Planet, Alexandra Jellicoe offers a story with the provocative headline Is Science Sexist?, which spins off an anecdote from astronomy: I was listening to Radio 4 a few months ago and the discussion about gender intelligence lodged in the deeper recesses of my brain unthought-of until recently when I went…
Launch Pad for Quantum Physics
Posted by Chad Orzel on July 19, 2010 Over at Jeff Vandemeer’s blog, Rachel Swirsky has a series ofm guest posts (start here if you prefer direct post links) about the recently completed Launch Pad workshop. this is a NASA funded workshop bringing a group of writers together for six days of lectures on modern astronomy from working astronomers. From the workshop web…
Holy Grails of Science
Posted by Chad Orzel on July 14, 2010 With the rumors of a Higgs Boson detected at Fermilab now getting the sort of official denial that in politics would mean the rumors were about to be confirmed in spectacular fashion, it’s looking like we’ll have to wait a little while longer before the next “Holy Grail” of physics gets discovered. Strictly speaking, the…
Through the Wormhole
Posted by Chad Orzel on June 10, 2010 The Science Channel debuted a new show last night, Through the Wormhole with Morgan Freeman, with the premier apparently designed by committee to piss off as many Internet types as possible. The overall theme was “Is there a creator?” and it featured physicist-turned-Anglican-priest John Polkinghorne talking about fine-tuning but no atheist rebuttal. It spent a…
