Setting up a python 3.x Virtual Environment

Step 0: Set up python virtualenv

virtualenv is a command-line utiltity that will allow you to encapsulate a python environment. Ubuntu calls the package that installs this utility "python-virtualenv". You can install it with $ sudo apt-get install python-virtualenv.

Step 1: Create the virtualenv directory

In this sequence, I'm going to assume that python 3.5 is the installed verison.

Mathematics: What do grad students in math do all day?

Mathematics: What do grad students in math do all day?

by Yasha Berchenko-Kogan

A lot of math grad school is reading books and papers and trying to understand what's going on. The difficulty is that reading math is not like reading a mystery thriller, and it's not even like reading a history book or a New York Times article.

The main issue is that, by the time you get to the frontiers of math, the words to describe the concepts don't really exist yet. Communicating these ideas is a bit like trying to explain a vacuum cleaner to someone who has never seen one, except you're only allowed to use words that are four letters long or shorter.

What can you say?
