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.

“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.”

“When Walser first put on his make-up, he looked in the mirror and did not recognise himself ... he experienced the freedom that lies behind the mask, within dissimulation.”

“I laugh when I think that all of Rome made it a point not to pronounce Drusilla’s name. Because Rome was mistaken for all those years. Love is not enough for me, and I understood that then.... To love someone is to accept to grow old with her. An old Drusilla is far worse than a dead one.”
—Albert Camus (1913–1960)
