We formulate a mathematical model for daily activities of a cow (eating, lying down, and standing) in terms of a piecewise affine dynamical system. We analyze the properties of this bovine dynamical system representing the single animal and develop an exact integrative form as a discrete-time mapping. We then couple multiple cow "oscillators" together to study synchrony and cooperation in cattle herds. We comment on the relevant biology and discuss extensions of our model. With this abstract approach, we not only investigate equations with interesting dynamics but also develop interesting biological predictions. In particular, our model illustrates that it is possible for cows to synchronize when the coupling is increased.

Все-таки математика - страшная сила. День еще толком не начался, а картина синхронно спаривающихся коров уже преследует меня.

масштабно!
важно, чтобы число коров в группе синхронного спаривания было четным.
а то...

Заглянул в статью. Да, эта штука посильнее Перельмана будет)
И еще вот это:
Acknowledgments. We thank Thomas Woolley for useful comments on a draft
of this manuscript, Puck Rombach for assistance with cow puns, and Yulian Ng for
drawing a spherical cow for us. JS and EMB gratefully acknowledges partial support

Ждем статью. где будет учитываться отклонение от сферичности
