Science and productivity by Dr. Christine Corbett Moran
Kliq soft launched this weekend. You can schedule a meetup (dinner, drinks, you name it) in just a few thumb taps with your local facebook friends or be adventurous and be introduced to a friend of a friend. This is just a taste of what’s to come. Get Kliq on the iPhone App Store at http://itunes.apple.com/lt/app/kliq/id412169676 or visit http://kliq.in. Read More …
Walls, filaments and voids: it is thought that the large scale distribution of matter is a complex network of galaxies and galaxy clusters connected by elongated filaments and sheetlike walls, outlining vast underdense regions known as voids and meeting at dense and compact regions known as haloes. Aragon-Calvo et. al. in [1] build upon the SpineWeb framework outlined in [2] , which has the capability of identifying these walls, filaments and clusters in cosmological simulations to examine the effect of environment (namely whether a galaxy is “living” in a wall or a void) on the dispersion of the Hubble flow around the Milky, which is significantly lower than theoretical expectations. They show that the measured dispersion could be a result of the fact that Milky Way resides inside a wall of radius around 10Mpc, which is supported by data. Read More …

A few weeks ago, Astrophysics Master’s student Tina Wentz gave a great overview of the phenomenon known as the Pioneer Anomaly in our gr-qc journal club. I’m indebted to her for that overview as well as pointing me to relevant papers in the preparation of this post. Background Launched in 1972 and 1973 respectively, the Read More …
Some of the most important equations in physics can be solved by constructing a beast with a curious set of properties, called a Green’s function. This post contains some interesting nuggets from a lecture I gave on St. Patrick’s day about Green’s functions to the course I assist, Mathematical Methods in the Physical Sciences II. I’ll Read More …
I stated 10 of my principles of teaching stream of consciousness today on twitter while preparing a lecture on Green’s functions. Principle #1: side with your students. Here are the rest…
