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…

Hubble Plateaus

In times past we have lovingly tracked the proposal frenzy as the near annual Hubble Space Telescope proposal deadline approaches. As was noted by Julianne several years ago, and confirmed over the last half dozen cycles, the shape of the curve of number of submitted proposals as a function of time until the deadline is…

The Curl of Space

Imagine you were a very clever ant, living on a large log, floating in a big lake… …a very large, deep, cold lake. Being a not incurious, clever ant, you contemplate the lake in its infinite and insurmountable vastness. Surely knowing what lies on the lake, or even beyond the lake (if such can be…

You are at university. Do you like stars, and stuff? We revisit old ruminations on career paths ’cause it is topical… Another rehashed blast from the past. Should you do astronomy as an undergrad? (the following is in part shamelessly cribbed from a colleague’s previous freshman seminar for our majors): Do you like stars and…
