In astrophysics, a magnetic mirror point is a point where the motion of a charged particle trapped in a magnetic field (such as the Earth's) reverses its direction. More precisely, it is the point where the projection of the particle's velocity vector in the direction of the field vector is equal to zero.
Famous quotes containing the words magnetic, mirror and/or point:
“We are in great haste to construct a magnetic telegraph from Maine to Texas; but Maine and Texas, it may be, have nothing important to communicate.”
—Henry David Thoreau (1817–1862)
“We should be a mirror of being: we are God in miniature.”
—Friedrich Nietzsche (1844–1900)
“Where there is no style, there is in effect no point of view. There is, essentially, no anger, no conviction, no self. Style is opinion, hung washing, the calibre of a bullet, teething beads.... One’s style holds one, thankfully, at bay from the enemies of it but not from the stupid crucifixions by those who must willfully misunderstand it.”
—Alexander Theroux (b. 1940)
