Because 4% of the Energy Controls 100% of the Photons

“I work around the clock– 1043 Planck times per second– providing the gravitational attraction to hold this galaxy cluster together. And some baryonic cosmologist wants to explain me away as a modification of Newtonian gravity? “I have been silent for 13.7 billion years, but no more. “I AM THE 96%” (Original Pandora Cluster image from… Continue reading Because 4% of the Energy Controls 100% of the Photons

Strongly Correlated Physics in a Superposition State

It’s been a while since I posted anything science-y, and I’ve got some time between flipping pancakes, so here’s an odd thing from the last few weeks of science news. Last week, there was an article in Nature about the wonders of string theory applied to condensed matter physics. This uses the “AdS/CFT” relationship, by… Continue reading Strongly Correlated Physics in a Superposition State

Donors Choose Fundraiser: Double Your Impact

I’ve been too busy to really work on the DonorsChoose fundraiser this year, but it’s worth taking a little time to mention this opportunity: Starting today and running through Saturday midnight, the DonorsChoose board will match donations to the Science Bloggers for Students fundraiser. thus, a $5 donation becomes $10, $10 becomes $20, and, well,… Continue reading Donors Choose Fundraiser: Double Your Impact

Experimentalists Aren’t Idiots: The Neutrino Saga Continues

In a lot of ways, the OPERA fast-neutrino business has been less a story about science than a story about the perils of the new media landscape. We went through another stage of this a day or two ago, with all sorts of people Twittering, resharing, and repeating in other ways a story that the… Continue reading Experimentalists Aren’t Idiots: The Neutrino Saga Continues

SteelyKid the Builder

Because it’s been a while since I posted a cute toddler picture, and because SteelyKid actually let me shoot some pictures of her yesterday for the first time in a while. Here she is, playing with Legos: Of course, building giant towers is only half the fun of playing with Legos:

Active Learning Experiment: The Halfway Point

Tuesday was the last day of the fifth week of classes (out of ten; for reasons that passeth all understanding, we started on Wednesday, so all the week-based deadlines fall on Tuesday). Accordingly, it seems like a decent time for an update on the active learning stuff I’ve been doing in my classes. Each class… Continue reading Active Learning Experiment: The Halfway Point
