Power functions are a special case of power law relationships, which appear throughout mathematics and statistics.
Famous quotes containing the words power and/or function:
“Do thou, then breathe those thoughts into my mind
By which such virtue may in me be bred
That in thy holy footsteps I may tread:
The fetters of my tongue do thou unbind,
That I may have the power to sing of thee
And sound thy praises everlastingly”
—Michelangelo Buonarroti (1474–1564)
““... The state’s one function is to give.
The bud must bloom till blowsy blown
Its petals loosen and are strown;
And that’s a fate it can’t evade
Unless ‘twould rather wilt than fade.””
—Robert Frost (1874–1963)
