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?

tmux cheatsheet

As configured in my dotfiles.

start new:

tmux

start new with session name:

tsabat

Prereq:

apt-get install zsh
apt-get install git-core

Getting zsh to work in ubuntu is weird, since sh does not understand the source command. So, you do this to install zsh

wget https://github.com/robbyrussell/oh-my-zsh/raw/master/tools/install.sh -O - | zsh

    Hey guys!
    This is a the first python program(except hello worlds) I have written.
    With HTTPServer, I can easily write a webserver.
    Python is such a powerful language that many complicated problems can be
    solved by a few lines of code.

    Welcome to visit my blog: www.xiaoxia.org
    The proxy program is just coded for fun <img src="http://xiaoxia.org/wp-includes/images/smilies/icon_smile.gif" alt=":-)" class="wp-smiley">
