“It contains four-dimensional equivalents to our familiar three-dimensional geometrical objects-a four-dimensional cube, for example, known as a tesseract, that has sixteen corners and thirty-two edges to a cube's eight and twelve.”
“There's a theory of extradimensionality that holds that there are parallel universes as little as a mere .1 mm away from our own, but owing to the dimensions of our own universe (that is to say, it is folded over on itself like a sort of endless ribbon - think "tesseract" from "A Wrinkle in Time"), we are billions of light-years away from the next nearest universe, as the crow flies.”
“Despite the fact that various advances made since 1962 in the field of physics make the scientific concept L’Engle uses to facilitate the novel’s events, called a tesseract, virtually impossible, A Wrinkle in Time remains a popular novel among young adults as well as older readers even today.”
“Thus the "four-dimensional cube" receives a name, the "tesseract," and is said to be bounded by cubes.”
“For instance, the projection of a cube may be made on to a plane, or even on to a line; similarly, a "tesseract" (the name given to the fourth-dimension figure traced by the motion of a cube) may be projected on three-dimension space, or even a plane.”
“Julian: Your desire for a dinghy is merely the tesseract shadow cast by the four-dimensional dinghy itself”
“In your spacetime version, when you reach this step, you need to grab the center of the structure and do the tesseract twist, wrench it round by about half a rad.”

“Speaking of ways, by the way, there is such a thing as a tesseract.”
“I went over to the computer, entered tesseract UMBC Baltimore 1995, and found the report.”
