I think eyebrows are the symmetry of the face. If they're not balanced and brushed up in the right way, your face looks kind of messy.
My goal is always to bring a sense of balance, symmetry, and proportion to each individual face. The brows are an essential starting point.
The nearest approach I have ever seen to the symmetry of ancient sculpture was among the Arab tribes of Ethiopia. Our Saxon race can supply the athlete, but not the Apollo.
At the end of the day, inflation has been below 2% for quite a long time, and to me, symmetry means getting somewhere above 2% inflation at some point in my Fed career.
The law of right-left symmetry was used in classical physics but was not of any great practical importance there. One reason for this derives from the fact that right-left symmetry is a discrete symmetry, unlike rotational symmetry, which is continuous.
The existence of symmetry laws is in full accordance with our daily experience. The simplest of these symmetries, the isotropy and homogeneity of space, are concepts that date back to the early history of human thought.
If you look at music, you see theme, variation, you see symmetry, asymmetry, you see structure, and these are related to skills in the real world.
