Triangle Inequality for Altitudes

I’ve written a short post on the triangle inequality for altitudes. As usual, I put it over on the math blog I have with my company, just because the support for literally everything is much nicer.

But, in the off chance you want it, I have a PDF. I’ve played around with a wonderful program called Typora, which I’ve been using for a few months to write any blog posts when I’m not in my iPad. It has great Mathjax support (miles better than WordPress), and so it’s easy to switch between the blog I use and this program, and I can export cleanly to PDF, as well as EPub and other formats that are really difficult to work with if I were using straight up LaTeX.

Are You Ready?

Assessments are a tricky business. Writing an exam that successfully tests a person’s knowledge or abilities, without inadvertently giving preference or advantage to certain demographics, is very difficult. The examinations I’ve written so far for my job fall into the category of testing whether a student has mastered a certain curriculum. After a couple of months of class, we give them an exam to check if they learned all that they were supposed to. Everybody is used to such tests, and everybody has experienced them.

I Promise I Like It

For the last two months I’ve been reading Crime and Punishment, by Fyodor Dostoyevsky. I’ve legitimately enjoyed the book whenever I’ve sat down to read it, but there is something about it that doesn’t quite grab my attention. I’ve struggled to sit down for very long stretches and just finish it out, and I can’t put my finger on why.

Brief Thoughts on Commencement

Due to travel and being home in Minnesota all last week, this post is coming late today.

This past weekend, my girlfriend graduated from college. It was an exciting time, and she officially finished up this chapter of her life and began to look forward to the PhD program she begins in the fall. Going to commencement was exciting, having this official moment to mark the occasion. This is what I appreciate about commencement, is its role as the milestone.

I don’t think I fully appreciated my commencement in the moment. Being in a major where I didn’t know many people, it was even a little isolating to not share the entire time with my friends. Yet it is still an event I can look back at to finalize the accomplishments I had in college. It’s also the last time something like that occurs. It felt to be one of the biggest jumps into adulthood, as there were no more obvious goals set out for me, beyond survival as an adult.

I think it’s good to have times where we can celebrate ourselves, to take the moment necessary to truly reflect on what we’ve done and where we are going after the fact. I hope to be cognizant of that feeling moving forward. Although there will be no institutions to celebrate my personal accomplishments, I want to take the time to reflect regularly, acknowledge what I’ve done, then focus on moving forward.
