Wonders of Math - The Game of Life

Wonders of Math - The Game of Life
What is the Game of Life? by Paul Callahan Rules of the Game of Life Life is played on a grid of square cells--like a chess board but extending infinitely in every direction. A cell can be live or dead. A live cell is shown by putting a marker on its square. A dead cell is shown by leaving the square empty. To apply one step of the rules, we count the number of live neighbors for each cell. A dead cell with exactly three live neighbors becomes a live cell (birth). Note: The number of live neighbors is always based on the cells before the rule was applied. In Life, as in nature, we observe many fascinating phenomena. The rules described above are all that's needed to discover anything there is to know about Life, and we'll see that this includes a great deal. Life Patterns A good way to get started in Life is to try out different patterns and see what happens. The R-pentomino is the first pattern Conway found that defied his attempts to simulate by hand. How Complex Can Life Get?

Crossword Puzzle Games - Play Or Create Your Own Puzzles Math Monday: Hula Hoop Geometry, Part 1 By Glen Whitney for the Museum of Mathematics Math Mondays have so far featured a wide array of different items from which one can make a tremendous variety of geometric constructions, but there has not yet been one on hula hoops. This week and next we’ll remedy that oversight. Also, the postings so far have almost entirely shown the constructions as fait accompli, so this series will also try to give a bit of insight into the process of devising a new creation. First, why hula hoops? Assignment: can you do the same thing with six hula hoops? For a recent event, MoMath wanted a large-scale public construction activity, so based on our success with hula hoops to date, designer Tim Nissen envisioned a gigantic pyramid of hoops — here’s the initial conception: Now that’s a lot of hoops, so we decided to try a Sierpinski tetrahedron instead of a solid pyramid, which is at least as mathematically cool and requires significantly less material. Total structural collapse, leading to hula chaos!

Noam Chomsky on the Purpose of Education by Maria Popova On the value of cultivating the capacity to seek the significant. In this talk based on his presentation at the Learning Without Frontiers conference in January, philosopher, linguist, and cognitive scientist Noam Chomsky — easily one of our time’s sharpest thinkers — discusses the purpose of education. Despite the slow pace and the cheesy AfterEffects animated typography, the video is a treasure trove of insight on everything from the role of technology to the pitfalls of policy. On the industrialization of education, echoing Sir Ken Robinson’s admonition about its effects on creativity: There have been many measures taken to try to turn the educational system towards more control, more indoctrination, more vocational training, imposing a debt, which traps students and young people into a life of conformity… That’s the exact opposite of [what] traditionally comes out of The Enlightenment. On technology: Technology is basically neutral. On the whimsy of inquiry: ↬ @openculture

Bac à Maths Douglass Academy walkout earns suspensions for about 50 high schoolers About 50 high school students at Frederick Douglass Academy in Detroit were suspended Thursday after walking out of classes to protest a host of issues at the all-boys school. The concerns included a lack of consistent teachers and the removal of the principal. The boys, dressed in school blazers, neckties and hoodies, chanted, "We want education!" as they marched outside the school. Parents organized the walkout because they fear for the school's future. As recently as last month, students spent weeks passing time in the gym, library or cafeteria due to a lack of teachers, parents said. Worries escalated after district offices moved into part of the building in January, and the school was not listed as an application school for next year. In addition, the school's founding principal, Sean Vann, was reassigned when he returned Wednesday after a three-month sick leave. "They're failing these young black men," said Sharise Smith, who has two sons at Douglass.
