Snow Rollers
Via Pharyngula, we found this wonderful page at NOAA about Snow Rollers, which is how nature stocks up for snowball fights. Seriously, when wind and snow conditions are just right (i.e. when the ground surface has an icy, crusty snow, … Continue reading
State of the Union
Over at Chris Mooney’s blog there’s an interesting post about Bush embracing Science in the latest state of the union speech. Since part of our research is on nanotechnology, and we’re insatiable users of supercomputing facilities, I certainly noticed this … Continue reading

BKChem
Apologies for the light posting. I’m teaching a new course for me: General Chemistry II, and the load for lecture prep has been substantially higher than normal. We just had BKChem submitted as a software link for our Molecular Viewers … Continue reading

Pup Ponders the Heat Death of the Universe
For your enjoyment, we present this link to “Pup” Ponders the Heat Death of the Universe from Drew Weing. I like Drew’s comics because he messes with the boundaries of the medium. Here’s one where he lets you choose your … Continue reading

OOPSE hits version 3
My research group’s main simulation program is called OOPSE, and we’ve just released a major rewrite of this code which includes all sorts of new molecular dynamics bells and whistles. Our code now includes lots of parts bolted on from … Continue reading

URAPIV
This is cool: URAPIV is an open source Matlab Toolbox for Particle Image Velocimetry (PIV) analysis. Particle Image Velocimetry is a planar, non-intrusive, optical imaging measurement technique that allows for two-dimensional, high-resolution velocity vector fields of laminar and turbulent flows. … Continue reading

Where have all the cool kids gone? To ScienceBlogs, I guess.
ScienceBlogs looks like a project of Seed Magazine, but a bunch of cool science blogs (including Pharyngula, Living The Scientific Life, Uncertain Principles, and Chris Mooney’s blog, The Intersection) have all moved there in the past few days. All the … Continue reading

My God, it’s full of stars!
The Hubble telescope gives us an image worthy of Dave Bowman’s exclamation about the monolith. At HubbleSite.org, you can read about the panoramic view of the Orion Nebula. I particularly love the google-maps-style zoomable navigator of the 18000 x 18000 … Continue reading
