Complex Systems #171

One of the joys of the holidays and the University turning off the heating and locking us out, is that it provides time to catch up on things: papers, refereeing, recommendation letters, grading, syllabi, proposals, all the stuff one can rarely get to during actual working semester hours. And, sometimes, there is time for real…

A research group at Lawrence Livermore National Laboratory has produced ultrastiff ultralowdensity metamaterials by 3D printing of microarchitected microlattices. This is very cool – they do additive 3D printing using microstereolithography with nanocoating and postprocessing and can make self-similar lattices with densities varying by several orders of magnitude in bulk density but near constant stiffness.…

Day two of the New Frontiers wrap-up conference. This is a slow liveblog with more cosmology and life in the universe. Yesterday’s summary is here A couple of years ago, the Templeton Foundation funded the New Frontiers program to pose “Big Questions” in some areas of science. This is a slow liveblog – part II…

A couple of years ago, the Templeton Foundation funded the New Frontiers program to pose “Big Questions” in some areas of science. This is a slow liveblog – part II will be tomorrow with more cosmology and life in the universe Seed funding was provided to 20 investigators and small groups to start exploratory research,…

Senior Review is out: summary – Swift #1, then NuStar. K2 gets partial funding. Spitzer is terminated. Panel recommends not cutting off the bottom but balancing fields. NASA Response to the 2014 Senior Review for Astrophysics Operating Missions – Final Version for Release (5.16.14) – this is an edited update of the NASA response that…

Why Fortran Lives

Julia is a nifty new language being developed at MIT I stole this plot from github, it shows Julia’s current performance on some standard benchmarks compared to a number of favourite tools like Python, Java and R. Normalized to optimized C code. And, there, in a single plot, is why Real Programmers still use Fortran…!

Backreactions

A frightening fraction of my open tabs are some of Bee’s posts at Backreaction – so to save my browsers, I dump them here for further future perusal: Are irreproducible scientific results okay and just business as usual? Shut up and let me think Should the Nobel Prize be given to collaborations and institution? Women…
