0-enigma simulation. 2-grid game. 3-healing grid. Ryota Kanai Utrecht University, The Neatherlands (© 2005 Ryota Kanai) The image is regular at the center, but the grid pattern is less regular at the peripheral parts of the images (both on the left and right edges).

As you stare at the center of the grid for say 20 seconds, the regularity of the grid pattern at the center spreads into the irregular parts in the periphery. This illusion seems to indicate the preference of the visual brain to see regular patterns.

Matrices. Each element of a matrix is often denoted by a variable with two subscripts.

For instance, a2,1 represents the element at the second row and first column of a matrix A. Applications of matrices are found in most scientific fields. In every branch of physics, including classical mechanics, optics, electromagnetism, quantum mechanics, and quantum electrodynamics, they are used to study physical phenomena, such as the motion of rigid bodies. In computer graphics, they are used to project a 3-dimensional image onto a 2-dimensional screen. In probability theory and statistics, stochastic matrices are used to describe sets of probabilities; for instance, they are used within the PageRank algorithm that ranks the pages in a Google search.[4] Matrix calculus generalizes classical analytical notions such as derivatives and exponentials to higher dimensions.

The numbers, symbols or expressions in the matrix are called its entries or its elements. Matrices are commonly written in box brackets: 5-spacetime curvature.
