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.

Wholemovement and The Art of Folding Circles

Last week, I discovered Wholemovement, an interesting origami site about folding circles. The site highlights the beauty of circles and exhibits variety of 3D shapes that can be constructed from it.

To those who want to try the basics, you can read how to fold circles. The page includes procedures on creating a sphere, a tetrahedron, an octahedron, and an icosahedron using a circle. You may also want to explore the Gallery page to view more complicated folds.

Paper folding is closely related to mathematics. We can consider creases as lines, and intersections as points. Folding papers emphasizes congruence, symmetry, and transformation.

To those who are interested in this topic, check out Professor Kazuo Haga’s book Origamics. It is an excellent resource on the mathematics of problem solving.

SOMEBODY up there pushed me

I am one of the youngest in our institute, and there are only a few of us who are about my age.  Most of my colleagues are over 40, and one of the hottest topics during break time is about retirement.  Some, when they retire, want to travel to other countries; some want to tend their grandchildren; and some want to live a simple life in their respective provinces.

There are other employees, however, who did not plan to retire at all. A few of them still go back regularly to our institute to work: they edit manuscripts, write books, train teachers, and do all the things they used to do. What is more amazing is that most of them do it for free — well, they are given little honorarium, but I doubt if it’s even enough for their lunch and gasoline.
