Math Overflow has an interesting question about unexpected mathematical images. Here’s a response from Payam Seraji that was easy to code up. Here’s the code that produced the image. from numpy import * import matplotlib.pyplot as plt t = linspace(0, 39*pi/2, 1000) x = t*cos(t)**3 y = 9*t*sqrt(abs(cos(t))) + t*sin(0.2*t)*cos(4*t) plt.plot(x, y, c="green") plt.axes().set_aspect(0.3) plt.axis('off') The post Simple equations whose plot looks like field grass first appeared on John D.
