The Tangent Space is a collection of scientific and computational odds and ends I've worked on over the years. I am mostly interested in early universe cosmology and particle physics, but I like to think about problems in other areas, too. I find that writing about stuff is a great way to learn, so I hope to have new articles up from time to time across a range of topics—math, cryptology, cybersecurity, even philosophy—in addition to my regular stuff on cosmology.

As a matter of introduction, that's me over on the bottom-right, along with my favorite things: my beautiful wife, Mrs. TS, my town, Greenbelt, MD, and cats.
