All images were taken with a stock Unistellar eVscope 2 at Lucile Miller Observatory in Maiden, NC and are unprocessed. LMO is operated by the Catawba Valley Astronomy Club. Images should have alt text, so if that is not working please let me know.

Up and Running with TeXShop Engines

In the previous post, I talked you through setting up MacTeX and bundled Mac apps. In this post, I want to introduce you to TeXShop, a powerful piece of software that is so much more than a text editor. At first glance, TeXShop is “just” a text editor. This shouldn’t surprise anyone since TeX or […]

Up and Running with MacTeX

With the release of TeX Live 2022 earlier this week, I decided this is a great time to describe how to install a full TeX Live distribution on Macs. I will also go further and describe how to maintain that distribution, keeping packages up to date. Sorry Windows users. I haven’t touched a Windows machine […]

A New Model for Academic Faculty V: One Problem Solved

TL;DR Some have raised the issue of accreditation for faculty teaching in private practice. The solution is deceptively simple. Faculty working in private practice would simply invent a brand new accreditation standard for ourselves. Problem solved. This is not without precedent. Furthermore, there is existing proof that accreditation is a red herring. Home schooling is […]

A New Model for Academic Faculty IV: One Can’t Fix What Isn’t Really Broken

TL;DR I conclude that the equity movement is well intentioned but is a waste of time until we reassert classroom autonomy that has literally been taken from us by administrators and outside parties (e.g. the testing industry), and autonomy that we have ceded without resistance. Once again this is mostly a brain dump of thoughts […]

A New Model for Academic Faculty III: Grading for Equity

TL;DR After attending a recent conference on Grading For Growth hosted by The Grading Conference I have read Grading for Equity by Joe Feldman. I am totally on board with this movement, and over the past few years have independently stumbled onto most of the basic findings described in the book. However, I think the […]

A New Model for Academic Faculty II: Further Thoughts

TL;DR Building on the previous post, here are some slightly more concrete thoughts on what may be possible in the future. As a self proclaimed community of problem solvers, we have not done a good job at solving major problems in teaching physics, or teaching in general. Too many of us have ceded authority to […]

The World’s Most Annoying Negative Sign

TL;DR If you want a quick way to gauge whether or not students understand the concept of potential energy, you can ask them to explain the origin of The World’s Most Annoying Negative Sign. It is merely a consequence of the very definition of potential energy, which is almost never explained coherently. In all of […]

Different Test or Assessment Questions

TL;DR In this pandemic year, cheating has been a major concern. One way of mitigating its effect is to ask questions beyond the traditional “Calculate…” type of physics problem. I present a list of possible questions that can’t be easily searched online and even if they’re found the answers are not as likely to be […]

The Hypocrisy of Traditional Tests

TL;DR Traditional tests require students to work a few (hopefully) appropriately chosen, illustrative problems to demonstrate proficiency. What does it matter if they do these few problems early in the semester or later in the semester? What does it matter if they do them with us watching or not? What makes one essentially random problem […]
