## Points, Pixels, and Pointillism

Points are building blocks of Geometry, it is one of those undefined terms.   If we can recall a point is “that which has no length, width, or height.” We also remember that a point is represented with (x,y), where x is the horizontal and y is the vertical; and, that in maps, a point represents a location. We are also familiar that points are represented by dots.

If points are important in Geometry, they are also important for painters especially those who use the technique called pointillism. In pointillism, paintings are created meticulously using dots to form figures and sketches.  The painting above titled A Sunday Afternoon on the Island of La Grande Jatte (1884-1886) by Georges Seurat is an example of a painting where pointillism was used. The painting’s dimensions are approximately 2 by 3 meters and it was created painstakingly for two years. » Read more

## Origami and Its Surprising and Stunning Applications

Last year, I shared to you about Professor Haga’s superb book on the mathematics of origami titled Origamics: Mathematical Explorations Through Paper Folding. Yesterday, I found the video below on Facebook about origami and its relationship to mathematics, as well as its numerous surprising applications. Watch and be amazed.

Sometimes, I want to believe that somehow everything is connected to everything else. Well, I think physicists already believe that.

## Origami and GeoGebra – a slightly different version

For GeoGebra enthusiasts who are attending GeoGebra conferences, don’t throw your GeoGebra flyers. Watch the video and see how useful it is. 🙂
