Quitting smoking = depression? I quit smoking cigarettes seven days ago. I've quit before and I understand that this horrible loneliness and depression are just some of the withdrawal symptoms, but I don't know how to lessen the depression. Most of my friends are smokers, so I'm not going out much and I live alone.
A tessellation is a regular pattern made up of flat shapes repeated and joined together without any gaps or overlaps. These shapes do not all need to be the same, but the pattern should repeat. Another word for tessellation is tiling.
It comes from the Greek tesseres, which means four.. The first tilings were made from square tiles. As an art form, tessellation is particularly rich in mathematics, with ties to geometry, topology and group theory. Cultures ranging from Irish and Arabic to Indian and Chinese have all practiced tiling at various levels of complexity.
