Reader Poll: ScienceBlogs Front Page
I’m kind of curious about how people read the site, in particular the ScienceBlogs front page, so: I look at the ScienceBlogs front page:customer surveys As a bonus, if you feel so inclined, take a look at the front page, and leave a comment letting me know what you think. Is there something they ought […]
The Elusive Digital Native
Inside Higher Ed featured one of those every-so-often articles about the awesomeness of the demographic subgroup of the moment, this time Athur Levine’s panegyric about “digital natives”, who “grew up in a world of computers, Internet, cell phones, MP3 players, and social networking,” and how they’re too cool and tech-savvy for current universities: They differ […]
Knowing What’s Essential Is Essential
Spinning off a blog at Inside Higher Ed, the Dean Dad has a post on deciding what classes are essential: My personal sense of it is that the distinction between core and periphery is largely a function of purpose. If your goal in life is to be an exhibited artist, then you might well decide […]
The Past and Future of the Laser
While it’s not aprt of the official LaserFest package of stuff, Physics World is marking the 50th anniversary of the laser with a couple of really nice pieces on lasers in science and popular culture: Where next for the laser interviews six laser experts– Claire Max of UCSC, Bill Phillips of NIST, Steven Block of […]
The World Doesn’t Need More Promotional Blogs
Over at the Book Publicity blog, Yen takes up the question of Internet publicity (via SF Signal): Yesterday I spoke at an AAR / Association of Authors’ Representatives panel together with Connor Raus (who runs digital advertising agency CRKWD) about understanding social media and how to use it effectively — as you know, a favorite […]
Laser Smackdown: Final Days of Voting for the Most Amazing Laser Application
We’re just over 600 votes in the Laser Smackdown poll in honor of the 50th anniversary of the laser, as of early Friday morning. I notice that it has moved off the front page of the blog, though, so here’s another signal-boosting repost, just so we have as many votes as possible, to establish maximum […]
Laser Smackdown: Vote for the Most Amazing Laser Application

Now, in 2010, as we celebrate […]
Amazing Laser Application 12: Laser Guide Stars!
What’s the application? Producing artificial “stars” to serve as a reference for telescopes using adaptive optics to correct for atmospheric turbulence. This allows ground-based telescopes to produce images that are as good as those from the Hubble Space Telescope. What problem(s) is it the solution to? “How can I make this giant telescope produce even […]
Amazing Laser Application 11: Frequency Combs!
What’s the application? An optical frequency comb is a short-duration pulsed laser whose output can be viewed as a regularly spaced series of different frequencies. If the pulses are short enough, this can span the entire visible spectrum, giving a “comb” of colored lines on a traditional spectrometer. This can be used for a wide […]
