"Hypercube" Natural Recordings by Native Speakers
A hypercube, also known as a tesseract, is a four-dimensional cube. It is a geometric shape that extends the concept of a cube, which is a three-dimensional shape with six square faces, to four dimensions. In four-dimensional space, a hypercube has eight cubic cells or eight three-dimensional cubes as its facets, rather than just six square faces in a three-dimensional cube. The idea of a hypercube was first described by the Italian mathematician Benedetto Delfino in the 16th century, and was later popularized by the science fiction author Charles Howard Hinton in the 19th century.
