The Red Light District Part 2: The Light Bulb Paradox

Monday, June 9th, 2008

I had a post over the weekend where I claimed that life on a planet around a type M star (see classifications here) would be like living in a red light district. Not the sex part, just the red light part. M stars are cool as stars go, around 3000 Kelvin or a bit less, […]

Living Around an M-Star: the Red Light District

Saturday, June 7th, 2008

NOTE: I’m keeping the below post as originally written. It will be superseded by a post to come as the issue is more complicated than I appreciated. A friend of mine has a story coming out and wanted to doublecheck some issues of colors on a planet orbiting an M-star. My friend supplied me with […]

Post-Starburst Galaxies

Friday, June 6th, 2008

Here’s a good write-up of some work related to mine that was also presented this week in St. Louis at the AAS meeting.   It involves post-starburst galaxies, whose relationship to post-starburst quasars isn’t entirely clear to me just yet (I’m planning a project that should help answer that question to my own satisfaction next year).   […]

The Importance of Science in our Lives

Friday, June 6th, 2008

Brian Green has an op-ed in the New York Times speaking about the personal importance of science in our lives.   It is a good article, and meaningful, in my opinion.   Science has enabled you to read this post, but it has also done so much more.   Reflect on that. Sometimes I feel like I’m a […]

Return to the Moon? Good Idea or Bad?

Wednesday, June 4th, 2008

Gregg Easterbrook wrote an Atlantic June 2008 article “The Sky Is Falling” in which he argues for more attention to the issue of near-Earth asteroids, which I think are very much worth paying attention to. He also suggests that establishing a sustainable moon base is a waste of effort. Do you agree? My friend and […]

Press Conference Experience

Tuesday, June 3rd, 2008

I overslept and almost missed it yesterday!   The traveling, stress, and lack of sufficient sleep caught up to me.   I made it over okay, with a couple of minutes to spare.   I wanted to make some adjustments to the slides and practice the talk again just before the actual event, but didn’t have time. The […]

Post-Starburst Quasar Press Release/Conference Coming Monday Morning

Sunday, June 1st, 2008

A few weeks ago I mentioned I’d been asked to participate in a press conference regarding my research at the American Astronomical Society meeting in St. Louis.   Well, that happens Monday morning.   I’ll be posting the press release here to coincide with the press conference and will post about my experience afterwards.   I’m hoping it […]

Follow-Up on the Academic Ponzi Scheme

Friday, May 30th, 2008

I should have known that some astronomer would have already tackled, quantitatively, some aspects of what I discussed as an “Academic Ponzi Scheme” a few weeks ago.   Travis Metcalfe wrote a paper last year which is publically available here.   Here’s the title and abstract: The Production Rate and Employment of Ph.D. Astronomers Authors: Travis S. […]

Tenure

Thursday, May 29th, 2008

Yesterday I was going through the mail I’d missed while I’ve been traveling, and came across the official letter finally that I am being promoted to Associate Professor with tenure on July 1, 2008, the start of our fiscal year. Woo hoo! So I knew this was happening.   My department and department chair all supported […]

Great Mind-Meld I Missed: Scientific Accuracy in Stories

Thursday, May 29th, 2008

Over at www.sfsignal.com here.   Just plain missed it last week while I was traveling, which is dumb of me since sfsignal is one of the best sites to keep up with the science fiction world. MIND MELD: Scientific Accuracy in Stories Science fiction would be nothing without the science. Who doesn’t like reading about new […]

ROY G BIV

Tuesday, May 27th, 2008

My mother is reading Spider Star and liking it significantly more than Star Dragon, primarily because she feels more for the characters.   She hasn’t finished the book yet, but did tell me on the phone the other day that she’d noticed an error.   Not a typo, but an outright mistake. She claimed I’d gotten the […]
