Year 3 is a photographic study by the artist and filmmaker Steve McQueen of children during Year Three of their education at primary schools in London. [1] 76,000 children were photographed for the project, representing two-thirds of the pupils at London's primary schools. [1] All participants were aged seven or eight. [1]
The Symmetries of Things is a book on mathematical symmetry and the symmetries of geometric objects, aimed at audiences of multiple levels. It was written over the course of many years by John Horton Conway, Heidi Burgiel, and Chaim Goodman-Strauss, [1] and published in 2008 by A K Peters.
When comparing the symmetry type of two objects, the origin is chosen for each separately, i.e., they need not have the same center. Moreover, two objects are considered to be of the same symmetry type if their symmetry groups are conjugate subgroups of O(3) (two subgroups H 1, H 2 of a group G are conjugate, if there exists g ∈ G such that H 1 = g −1 H 2 g).
Octacube has very high intrinsic symmetry, which matches features in chemistry (molecular symmetry) and physics (quantum field theory). The sculpture was designed by Adrian Ocneanu , a mathematics professor at Pennsylvania State University. The university's machine shop spent over a year completing the intricate metal-work.
This article summarizes the classes of discrete symmetry groups of the Euclidean plane. The symmetry groups are named here by three naming schemes: International notation, orbifold notation, and Coxeter notation. There are three kinds of symmetry groups of the plane: 2 families of rosette groups – 2D point groups; 7 frieze groups – 2D line ...
Last week, a man who claimed his girlfriend had died from an overdose was sentenced to 28 years behind bars for killing her. Toby Loughnane, 45, of Melbourne, Australia, was found guilty of the ...
The Six Nations wooden spoon is heading Wales' way again after it lost to Italy 22-15 and earned more unwanted records on Saturday. Wales has never suffered consecutive last-place finishes in the ...
Quite the groovy decade of hosting and socializing with major flair, the 1970s were full of funky foods that became synonymous with the buffet tables laid out at every party.
