[Link] Statistics with Python

by Jessica Lu September 30, 2011

Astronomers rely on statistical analysis all the time. The Python programming language has some excellent add-on packages for statistics. But sometimes the documentation isn’t as helpful in “real-world” scenarios. Prasanth Nair has posted a very nice tutorial on Simple Statistics with Python over at his blog. I highly recommend it for new users of python […]

Visualizing Simulated Data

by Jessica Lu June 9, 2011

More and more astronomers are writing, running, and using massive computer simulations. The complexity of these simulations (often 3D space + time) means that visualization can be challenging. Over at Astropython, they have posted about the – yt – toolkit that allows you to analyze and visualize the results of adaptive mesh refinement simulation codes (AMR). AMR […]
