About

Hello! I'm Daniel Opdahl. Physicist, Computer Scientist, and Power Rangers fanatic.
I love cooking, hiking, Star Trek, the Foo Fighters, baseball, and D&D.
​​​​​​​You can find some of my personal coding projects, my resume, and ways to contact me below.

Projects

A project where I implement the algorithm described in the paper "A Pencil-and-Paper Algorithm for Solving Sudoku Puzzles" by J. F. Crook, published by the American Mathematical Society.
I use python to implement the algorithm, which solves any solveable sudoku puzzle.

A paper I wrote about the compelling short story "The Library of Babel" by Jorge Luis Borges for my Hispanic Literature class at Luther College.

You can read my essay below, or you can check it out on GitHub, where I also have notes I used in writing the essay as well as copies of the story in both English and Spanish.

Additionally, I highly recommend exploring https://libraryofbabel.info/.

A project to determine what the lowest number of each of the digits 0-9 are needed in order to reliably run a hand-turned scoreboard using Luther College Baseball line scores from the previous decade.

Final results of my analysis for the Luther College Baseball scoreboard are:
  • Twenty-five  0's
  • Thirteen  1's
  • Nine  2's
  • Nine  3's
  • Seven  4's
  • Seven  5's
  • Six  6's
  • Five  7's
  • Four  8's
  • Three  9's
You can read more about my methodology, see the source code, and hear the backstory of this project in my GitHub repository.

A project where I analyze how much the Houston Astros benefitted from cheating during the 2017-2019 MLB seasons by comparing the Astros' offensive performance pre-2017 against leage average, and the Astros' offensive performance post-2017 against leage average. Additionally, I look at the individual players on the Astros and attempt to quantify and qualify how much they as individuals benefitted from cheating.

A month-long research project done during January 2020 at Luther College about thermally pulsing AGB stars with the physics department. Owen Johnson and I used Luther College stellar data and open star cluster data to find the distance, density, and mass of roughly 20 stars in the M23 star cluster.
