Life on the Edge

This is probably the edgiest post I will ever write, because I want to talk today about edge cases. Like some of the concepts I described in my post on narrative physics, this is another instance of me taking an idea from a "hard" field (science, engineering, math) and applying it to a "soft" field (political science, philosophy, literature), and this time that concept is edge cases. If you're not familiar, an edge case is an engineering term used in testing to express failure modes. For a product to be deemed effective/safe/useful, it has to be rigorously tested, and not just under "normal" conditions; it has to be exposed to the most extreme and unusual conditions that the engineers can possibly imagine it might ever conceivably experience, and tested in that environment, too. Those extreme and unusual conditions are known as edge cases, and it is very common for a product to require redesign after it has met its nominal operating conditions because it fails to account for edge cases. If only that concept were applied outside of engineering.

Sententia Discussion Series

I am excited to announce that for 2021, IGC Publishing will be hosting a Sententia discussion series. This is something that I've wanted to do for quite some time, and have attempted before in various formats to varying degrees of success, so hopefully this forum will help finally promote the concept. Twice a month, I will post a "Sententia" here on the site, and it will be open for comments and discussion, the idea being to foster original thought and productive conversation about complex, relevant, and interesting topics.

For Sale: Lunar Regolith

I didn't put any really complex thought into deciding what the first educational post was going to be about; I just came across an article that I found interesting, and went from there. In this case, it was an article from NASA about purchasing lunar regolith (yes, is my browser's homepage). There were two, primary dimensions to this article, and they're worth analyzing independently: in-situ resource utilization, and international space law.
