Is there such thing as a tesseract?if so, what is it?

Question

I read about it in a book ( a wrinkle in time) but didnt fully understand it, but im interested in knowing!

Answer 1

I believe Madeline L'Engle made it up!

Answer 2

In geometry, the tesseract is the 4-dimensional analog of the (3-dimensional) cube, where motion along the fourth dimension is often a representation for bounded transformations of the cube through time. The tesseract is to the cube as the cube is to the square, or more formally, the tesseract can be described as a regular convex 4-polytope whose boundary consists of eight cubical cells. According to OED, the word tesseract was coined and first used in 1888 by Charles Howard Hinton in his book A New Era of Thought, from tesseres aktines = 'four rays' in Ionic Greek, referring to the four lines from each vertex to other vertices. Alternately, some people have called the same figure a 'tetracube'.

Answer 3

A tesseract is to a cube as a cube is to a square . But if u be trapped in a 2d world , u can't build a cube , and if a tesseract can only be built in a 4d world . U can define a tesseract in analitical geometry .
U can project a tesseract in 2d space , or 3d space .

Answer 4

It is a term coined by Madeleine L'Engle in her children's novel, "A Wrinkle in Time." It describes a folding of time to allow time travel.

Of note, this is the book where "It was a dark and stormy night..." comes from.

Answer 5

A 4-dimensional "cube". ie, finish this series:
a 2-dimensional object with all equal "line" (1D) sides, [a square]
take an infinite stack of them to make
a 3-dimensional object with all equal "square" (2D) sides, [a cube]
take an infinite stake of them to make
a 4-dimensional object with all equal "cube" (3D) sides: a tesseract!

Answer 7

tes·ser·act (tµs“…-r²kt”) n. The four-dimensional equivalent of a cube. [Greek tessera, neuter pl. of tesseres, four; see TESSERA + aktis, ray of light; see ACTINO-.]

Answer 9

DONT TRY TO PICTURE THIS:
A four dimensional cube.

Answer 10

No, not in the sence your thinking
