Part of the exercise in improving/building the reaction-diffusion simulator was so that I build the code needed to explore the next tattoo I plan on getting. I thought of this tattoo after a challenging vipassana course (although it was many years in the making). The tattoo represents my evolving relationship with engineering and science. The tattoo will be a Turing-pattern, generated via the FitzHugh-Nagumo equations, which is by-design, different in length scale to the patterns I generated in my final paper during my PhD. I initially was going to have it designed with pointilism, but since finding my tattoo shop I think I want to defer to them on artistic design. The key is that the design will have a sharp break in the middle that represents embryogenesis, the phenomena I find most fascinating in biology, and representing a break in my views/hopes of science. It’s an important transition for me away from viewing science as almost a spiritual endeavor to a more practical view of finding challenging problems without compromising on my lifestyle and goals.
