NoséHoover Attractor
This set of dynamical equations was found by Shūichi Nosé in 1984 when researching about molecular dynamics and thermal equilibrium distribution^{1}:
\[\dot{q} = \frac{p}{s^2}\] \[\dot{p} = q\] \[\dot{s} = \zeta\] \[\dot{\zeta} = \frac{p^2}{s^3}  \frac{T}{s}\]Further research by William Graham Hoover^{2} a year later simplified them to^{3}:
\[\dot{q} = p\] \[\dot{p} = q  \zeta\, p\] \[\dot{\zeta} = p^2  T\]Renders

Framing It
I liked the third render so much, that I printed it on 45×35 cm fineart paper and framed it. Read more in my blog post.
