Made with Julia version: 1.11.5
This short course is designed to introduce students to the Julia programming language applied to analysis for spectroscopy. It is intended for students who have never programmed before, or who have only done a little programming in another language. The goal is to teach the basics of programming in Julia, and to provide examples of how to use Julia for data analysis and visualization in spectroscopy. These lessons were not originally intended to be comprehensive, but they have evolved into somewhat of a complete introduction to programming. They should serve as a starting point for students to learn how to use Julia for their own research projects in experimental spectroscopy.
Lessons include short exercises to be done in class, and longer problems to be done outside of class.
These are organized by chapter in the chapters directory.
The code that generates the figures are in the generate_images directory.
Answers to the exercises and problems are in a separate repository, which is not included here.
Data needed for the exercises and problems is included in the data directory.
The src directory contains scripts that generate data for activites, as well as a script that generates a pdf file from the markdown chapters.
This directory needs to be cleaned up a bit....
The corresponding experimental tutorials can be found at the Optics Tutorials repository. The computer science tutorial is designed to set students up to analyze data obtained during the optics tutorials.
Chapters 1 through 6 cover programming fundamentals. These should ideally be covered in two weeks with about 1 hour of class time per chapter, and 2-3 hours of homework per week.
Chapters 7 through 10 cover data analysis and visualization. These can be covered in about a week, maybe a little more depending on how much detail is spent on each chapter.
