Some A&S Projects
- 2021 Crowns' A&S project page
- 2021 Crowns' A&S Research Paper
- Once the Crowns' A&S Championship website goes down, you can either read my full research paper or get the gist by reading the abstract of the paper, viewing the pattern I developed in the Appendix of the paper, and optionally view this math background video.
- The Real Fibonacci Numbers, a recording of an online class I taught for the Ethereal East Kingdom Online Class series in the spring of 2020. This class looks at the mathematician Fibonacci and his life and times, the sequence mathematicians have named for him and what he knew about it, and the sequence of numbers he actually studied in depth. Here's the class handout.

She was recognized by Thyra II with the Golden Lyre and Seamstress to the Crown.
Rosina's favorite things to do in the SCA are teaching and taking classes. Rosina has taught a number of classes on the history of mathematics in period. Most of these classes are on Fibonacci, the foremost Western European mathematician of the middle ages. Several of these classes are based on Fibonacci's 1202 book Liber Abaci, including arithmetic, extracting roots, algebra, and his example problems. Another class is on Fibonacci's Book of Squares, and another on Fibonacci's Practical Geometry. Rosina has also written an article for the EK Gazette on Fibonacci. She has also taught a class on 3-D geometry in Renaissance art and science, as well as a class on applying modern classification techniques to period narrowwork designs. Rosina has also taught a number of classes on fingerloop braiding at the basic, intermediate and advanced levels. She has taught several multiperson fingerloop braiding classes with her lord, Andreiko Eferiev, and with Thyra Eiriksdottir and Jeanne de Robin. Rosina has also taught a class on kumihimo once and a class on period drinking songs many times.
In addition to teaching and taking classes, Rosina enjoys running setup or class scheduling for events, dancing, singing, playing instruments including guitar, recorder and drums, thrown weapons, archery, knitting, and embroidery. She has also retained for Brenwen I, Alethea, Marguerite, Thyra I and II, and Fortune.
