Technology
In the public imagination, "maglev" often evokes the concept of an elevated monorail track with a linear motor. This can be misleading. While several maglev systems are monorail designs, not all maglevs use monorails, and not all monorail trains use linear motors or magnetic levitation. Some railway transport systems incorporate linear motors but only use electromagnetism for propulsion, without actually levitating the vehicle. Such trains (which might also be monorail trains) are wheeled vehicles and not maglev trains. Maglev tracks, monorail or not, can also be constructed at grade (i.e. not elevated). Conversely, non-maglev tracks, monorail or not, can be elevated too. Some maglev trains do incorporate wheels and function like linear motor-propelled wheeled vehicles at slower speeds but "take off" and levitate at higher speeds.

Famous quotes containing the word technology:
“Primitive peoples tried to annul death by portraying the human body—we do it by finding substitutes for the human body. Technology instead of mysticism!”
—Max Frisch (1911–1991)
“Technology is not an image of the world but a way of operating on reality. The nihilism of technology lies not only in the fact that it is the most perfect expression of the will to power ... but also in the fact that it lacks meaning.”
—Octavio Paz (b. 1914)
“The real accomplishment of modern science and technology consists in taking ordinary men, informing them narrowly and deeply and then, through appropriate organization, arranging to have their knowledge combined with that of other specialized but equally ordinary men. This dispenses with the need for genius. The resulting performance, though less inspiring, is far more predictable.”
—John Kenneth Galbraith (b. 1908)
