MAS212 Scientific Computing and Simulation (2019/20)

Lecturer: Dr Sam Dolan (G18)

The Barnsley Fern

This is the course web page for MAS212 Scientific Computing and Simulation in 2019/20.
Last year's material is here.

Course Information

MAS212 is a 10-credit, Level 2, first-semester module which covers various techniques in scientific computing, and their implementation in Python. The course is intended to follow on from MAS115 Mathematical Investigation Skills.

MOLE

This year I will also use MOLE for some course materials, such as video clips.

Software and setup

We will be using the Anaconda distribution of Python (version 3.7), which includes Jupyter Notebook and Spyder.

Anaconda3 is available on (the majority of) Managed Desktop machines. From the Start Menu, select the folder "Anaconda3 (64-bit)".

To install Anaconda on your own computer, use the link below, and choose the Python 3.7 version

Learning Resources

There are many books on Python and scientific computing. For this course, I recommend:

Copies are available in the library.

A range of material is available on the web, including:

Sample Notebooks

In this course we will use Jupyter notebooks to combine code, text, plots and media. To view a notebook in the browser, click on the links in the left column. (Alternatively, copy-and-paste the notebook's URL in to the box at nbviewer.jupyter.org).

To interact and modify a notebook, right-click on a link in the right column (.ipynb) and download to your Jupyter notebook directory.
