Ball of crumpled paper. In geometry and topology, crumpling is the process whereby a sheet of paper or other two-dimensional manifold undergoes disordered deformation to yield a three-dimensional structure comprising a random network of ridges and facets with variable density.
There will then be at least one point of the crumpled sheet that lies directly above its corresponding point (i.e. the point with the same coordinates) of the flat sheet. This is a consequence of the n = 2 case of Brouwer's theorem applied to the continuous map that assigns to the coordinates of every point of the crumpled sheet the coordinates ...
Poi can be performed in the dark to dramatic effect when spinners use poi containing a light source, such as UV-sensitive materials, LED lights, or chemical glow sticks. Glowstringing, or using glowsticks swung from shoelaces, is popular at festivals and raves. It is also noted that while poi focuses on the manipulation of the head (the other ...
John Cage composed this piece as a way of celebrating the work of Jean Arp on the occasion of the centenary of his birth. Jean Arp, an artist in which John Cage found much inspiration in the period the piece was composed in, created paintings and collages, circa 1915–1930, including maneuvers of chance, like dropping cutouts of paper or strings and cementing them where they fell.
In Gaucher disease, the enzyme is unable to function correctly and glucocerebroside accumulates. The macrophages that clear these cells are unable to eliminate the waste product, which accumulates in fibrils, and turn into 'Gaucher cells', which appear on light microscopy to resemble crumpled-up paper.

The retracted paper is an example of what happens when studies and the scientific record get politicized, said Ivan Oransky, co-founder of Retraction Watch, a scientific watchdog organization that ...
The 2024 NFL regular season ended after the Detroit Lions beat the Minnesota Vikings 31-9 in the "Sunday Night Football" finale to clinch the NFC North and the conference's No. 1 seed.. Once that ...
A piece of paper crumpled into a ball, representing a two-dimensional object distorted in the third dimension, making points that are far apart on its surface come close to each other or even touch. The basic premise of hyperspace is that vast distances through space can be traversed quickly by taking a kind of shortcut.
