Joy's Law
From Wikipedia, the free encyclopedia
Joy's Law may refer to two separate concepts.
In astronomy, Joy's Law describes sunspots and states that active sunspot regions tend to be "tilted" with the leading spot closer to the equator than the following spots.[1][2][3] It is named after A. H. Joy.
In management, it refers to the principle that "No matter who you are, most of the smartest people work for someone else,” attributed to Sun Microsystems co-founder Bill Joy.[4]
