Quantum Leap

Quantum Leap was a science fiction television program (ran from 1989 to 1993) following the adventures of Dr. Samuel Beckett (played by Scott Bakula) a brilliant theoretical scientist who finds himself abruptly and uncontrollably jumping in time, temporarily switching places with diverse people living throughout the second half of the 20th century. Sam's unfortunate travels begin when his time travel experiment gets mysteriously co-opted by an unidentified higher power, which uses him (for unknown reasons) to avert tragedies in ordinary people's lives. Sam also suffers from a forced selective amnesia, which the show calls "swiss cheese brain," which prevents him from remembering the details of his own life. His only link to his own time is a holographic* projection that only he can see named "Al" (played by Dean Stockwell). The catch-phrase used at the beginning of every episode was typically: "Oh boy..." The show's 97 episodes aired on NBC between March 1989 and May 1993.

(*note that the term "holographic projection" is taken from the program; the way the effect is depicted in the show is not remotely consistent with real holography, which is a specific process for creating three dimensional images. The "hologram" depicted in the series is more like a three dimensional projection, though in this case the science is never made entirely clear, and it may be they intended the term "hologram" to be a form of slang.)

The series very rarely addressed real historical events, though it often used its "ordinary people" plots to address particular social, political, and spiritual issues. Only once in the 97 episode run did Sam "leap" into a known historical figure (Lee Harvey Oswald). Other episodes depicted Sam dealing with social issues during particular periods, such as civil rights, racism, the Vietnam War, and the American/Russian Cold War. The series strongly favored messages of tolerance and understanding others, aided in large part by the story format, which forced the protagonist to literally "walk in another man's (or woman's) shoes."

The series (created by Don Bellisario) was somewhat unnusual in that it had a science fiction concept, but little science or fantasy oriented storytelling, instead focusing on the personal journeys of Sam Beckett and those he encounters. Even in its final episode, the show refused to resolve many of its own technical and holistic questions, choosing instead to leave things open-ended and focus tightly on the series' overarching message: that a single person can change the world one life at a time.

The final episode was in fact intended to be an end-of season cliffhanger, but after the series was not renewed by the network, the show was reedited to create the final episode. This accounts for some of the ambigious nature.

Bakula later went on to star in another science fiction television show as Captain Jonathan Archer in Enterprise.

Quantum leap

(From Wikipedia, the free Encyclopedia)

A quantum leap is an "abrupt change, sudden increase, or dramatic advance".¹ The term dates back to 1956.

The word Quantum (from Latin quantus, "how much?") dates back to the 16th century, meaning a quantity or amount. Today, the word is strongly associated with quantum mechanics, where it means an indivisible quantity or amount.

It is sometimes said that a phrase such as a quantum leap in technology is inappropriate, because "quantum" supposedly means "small" in quantum mechanics. So a quantum leap in technology would be a small advance. However, "quantum" does not actually mean "small" in quantum mechanics; it means "discrete", "indivisible", or "all-at-once". A quantum leap in technology would be an advance that happens all at once, rather than gradually over time. If advances are classified as either evolutionary or revolutionary, then a quantum leap in technology would be the latter.
