I just finished loading my old Cafe Press store with tons of different shirts and other odds and ends featuring my Bayesian graphic, which uses imaginative rather than standard mathematical notation (as I reported last week, you can get jewelry with it from SurlyRamics).
I also duplicated most items with a cool graphic design of the Odds Form of Bayes’ Theorem (in standard mathematical notation, but artful font). Because a lot of people are fans of the Odds Form. No joke…it has actual vocal fans. It’s also the form I use to run the math in my upcoming book On the Historicity of Jesus. If you want to know what the difference is and what the Odds Form equation means and how to use it, see Proving History (index, “Bayes’ Theorem, Odds Form”). Like with the other graphic (as I explained last week), you have to assume b (background knowledge) is in the givens of every term (a common assumption mathematicians allow).
To check out the full range of products, and help support my work by buying some, visit Richard Carrier’s Marvelous Amusements. Note that many items actually have color options at the purchasing page (so it’s not just all black or white). If you have ideas for other products I could develop and offer there, feel free to recommend them in comments here. Just note that I’m limited by the stock and capabilities of Cafe Press.
I have also included some Solon’s Commandments materials, as some fans requested I do many months ago, after I wrote about them in That Christian Nation Nonsense (Gods Bless Our Pagan Nation). Cafe Press doesn’t offer the option of an inscribed plastic plate, so you would have to get the mini-poster and put it in a hard plastic casement or sheath from a local office supply store–or else buy the expensive framed print option (although that does look quite nice). Junior high and high school students who feel like living dangerously can even bring a Solon’s Commandments lunch bag to school.
