Tattoo of Alison, a high-school physics teacher - from Carl Zimmer's Collection, at the Loom
Can’t tell which equation is the Mandelbrot Set, which the hydrostatic equation, which the description of entropy? Can’t figure out why the delta, and otherwise confused? Alison explains it all, at Carl Zimmer’s blog, The Loom.
It’s relatively clear that she didn’t get the tats to use them to cheat on any exams.
[...] Check out Millard Fillmore’s bathtub to see equations which are tattooed on someone’s back. One equation is the entropy equation, one is the hydrostatic equation, and one is for the [...]
Top equation is for the Mandelbrot set; it describes how to get a new point in terms of the old point.
The ds/dt > 0 is the entropy one; this means that entropy is always increasing (positive first derivative)
The hydrostatic equation is the remaining one; rho is specific gravity, “r” is distance, p is pressure ( I think)
