The Geometry of the Universe¶

This new book is to be published in July 2021.
I, Johnny Gill, have created this project as a place for a virtual guide to the book, as I work my way through it.
Install¶
git clone https://github.com/swfiua/gotu
python3 setup.py install --user
You may need blume from github too::
git clone https://github.com/swfiua/blume
cd gotu
python3 setup.py install --user
Running modules¶
Many modules can be run from the command line, often using argparse to parse options:
python3 -m gotu.spiral --sky
python3 -m gotu.gaia -h
Most of these use blume to provide a console and matplotlib plotting environment.
It is a strange console where single character commands can have interesting consequences.
To start the show, type:
magic.show()
This will pop up a magplotlib figure.
Type ‘h’ to see what does what.
Good luck on your adventure.
