Julia: Solving Real-World Problems with Computation, Fall 2024
(course material work in progress)

Real-world problems

We will take applications such as climate change and show how you can participate in the big open source community looking to find solutions to challenging problems with exposure to github and parallel computing.

An interactive lecture about climate economics. You can see the user moving the global CO2 emissions in one graph, and a second graph with global temperatures over 200 years responds.

Corgi in the washing machine

You will learn mathematical ideas by immersion into the mathematical process, performing experiments, seeing the connections, and seeing just how much fun math can be.

An image of prof. Philip the Corgi, but the whole image is swirled and twisted using a mathematical transformation. Overlaying grid lines are also twisted, showing the non-linearity of the transformation.

Revolutionary interactivity

Our course material is built using real code, and instead of a book, we have a series of interactive notebooks. On our website, you can play with sliders, buttons and images to interact with our simulations. You can even go further, and modify and run any code on our website!

An interactive lecture about the Newton method. A parabolic function is graphed, and we use sliders to control the number of iterations of the Newton method. Each iteration shows a tangent, demonstrating the algorithm.

Learning Julia

In literature it’s not enough to just know the technicalities of grammar. In music it’s not enough to learn the scales. The goal is to communicate experiences and emotions. For a computer scientist, it’s not enough to write a working program, the program should be written with beautiful high level abstractions that speak to your audience. This class will show you how.

A snippet of Julia code defining a new type called Sphere, with fields 'position', 'radius' and 'index of refration'.

Description

Focuses on algorithms and techniques for writing and using modern technical software in a job, lab, or research group environment that may consist of interdisciplinary teams, where performance may be critical, and where the software needs to be flexible and adaptable. Topics include automatic differentiation, matrix calculus, scientific machine learning, parallel and GPU computing, and performance optimization with introductory applications to climate science, economics, agent-based modeling, and other areas. Labs and projects focus on performant, readable, composable algorithms and software. Programming will be in Julia. Expects students have some familiarity with Python, Matlab, or R. No Julia experience necessary.

Counts as an elective for CEE students, an advanced subject (18.100 and higher) for Math students, an advanced elective for EECS students, and a computation restricted elective for NSE students. AeroAstro students can petition department to count this class as a professional subject in the computing area. (Professors may be open to petitioning for counting for other programs.)

Class is appropriate for those who enjoy math and wish to see math being used in modern contexts.

While not exactly the same as our past Computational Thinking Class... not entirely different either.

Course Objectives

  1. Making mathematics your playground: By the end of the course, students will be able to write interactive Julia code that aids in their understanding of new mathematical systems or concepts.
  2. Abstractions: By the end of the course students will be able to use the unique abstractions that exist in the Julia language to write code that can be part of a huge ecosystem. (By contrast many "one-off" homeworks in traditional courses are not able, by their very nature, to reveal the value of abstraction.)
  3. Open Source and group collaborations: By the end of the course students will be able to participate in a larger open source project and also will have experienced how programming language can help break down barriers between areas making real the dream of scientific bilinguals that has been promoted at MIT. (See for example former MIT President Reif in the NYT back in 2018.)
