New Software Links
A bunch of new software links today: First, in our Nuclear Physics section, we’ve been pointed to the Nuclear data analysis (histogramming) package and the Nuclear physics data acquisition system. The acquisition system is an event-based system that supports a … Continue reading

Terrorist states of matter
Very funny graphic borrowed from Cosmic Variance: So we live in a world where an entire state of matter is considered a national security risk. What I want to know is if Homeland security has considered the implications of the … Continue reading

CO-ADC, XMD, ChemiCool
We’re highlighting three new software submissions today: CO-ADC calculates band structures of semiconducting and insulating crystals. Electron correlations are accounted for using the crystal orbital algebraic diagrammatic construction (CO-ADC) scheme. The software comprises an independent band Lanczos code for real- … Continue reading
Software Carpentry Course
Greg Wilson pointed me to a new version of the Sofware Carpentry course at (www.swc.scipy.org); it’s all open source, and they’re actively looking for corrections and contributions. Reading through the online course materials, I can say that it is a … Continue reading
A Theory about Questions in Paper Titles
I have this hypothesis about scientific papers: If the title of the paper contains a question, the paper answers the question with a “no”. My own examples: Is the Ewald summation still necessary? Can imaginary frequency instantaneous normal modes predict … Continue reading

Fun with Bessel Functions
Almost everyone has seen that wonderful first picture of a “Quantum Corral” from the now-famous paper by Crommie, Lutz and Eigler (Confinement of electrons to quantum corrals on a metal surface. Science 262, 218-220 (1993)). The surface states of the … Continue reading

Design Patterns for Scientific Software
I’ve been reading a really interesting paper out of a group that’s just across campus from me. The paper is called Design Patterns for Generic Object-Oriented Scientific Software and it comes out of the Izaguirre Group. Design patterns have a … Continue reading
Worm-like chains
BioCurious has a really great review / research article on wormlike chains and the differences in the force-extension relationships between freely-jointed chains and wormlike chains. It is worth a read! [tags]biophysics, DNA[/tags]

Re-purposing Open Source projects for Science
I’ve been having discussions with my colleague, Alex Kandel, about a software tool he’s been working on. He has 20,000 or so STM images that his group has taken over the past five years, and he is building a web … Continue reading

Free-software licenses
Everyone should go read Brooks Moses on Free-software licenses: requirements vs. requests. His post has made me re-think the license we use for our group simulation code. I’ve never like GPL because it essentially guarantees that friends in the corporate … Continue reading
