The anisotropy means that light can scatter unevenly in this medium, these rays don't bounce around in all directions with equal probability.

各向异性表明光可以在此媒介中不平均地散射，这些光线不会以相同几率向四面反弹。

For it can easily be shown that the assumption of arithmetically equal probabilities based on a state of ignorance leads to absurdities.

因为可以很容易地证明，基于无知状态的算术上相等概率的假设会导致荒谬。
