Black Forest German Cuckoo Clock Chimes incorrectly?

Jan 04, 2008 by Jen | Posted in Other - Home & Garden

Hey, my mother a cuckoo clock from Germany's Black Forest, she bought last year. One day, while fixing the time (at the level it should be), she accidentally struck the hour hand. Since then, the clock will ring at the correct time.

The hour hand on most mechanical clocks has a sliding fit to the hub. All you have to do is wait and fix it chimes the hour hand to match the hour has struck.

You can turn in both directions, but I've always rotate.

Robert Lang: Folds a New Origami « The TEDx Project

by Christian Long

Dr. Robert. Lang is an America physicist who is also one of the famous origami artist in world.

He is known for his complex designs, of insects and animals. He has been a student of the mathematics of origami and of using computers to study the theories behind origami. He has made great advances in making real-world applications of origami to engineering problems. Robert Lang merges mathematics with aesthetics to fold elegant modern origami. His scientific approach helps him make folds once thought impossible.

Most people think origami is just paper swans and toys. Robert Lang describes origami as an art form of sculpture.

Origami, as Robert Lang describes it, is simple:

He also describes it as “art work formed with technology and mathematics.”

His models includes a snake with one thousand scales, a two-foot-tall allosaurus skeleton, and a perfect replica of a Black Forest cuckoo clock. Each work is the result of software which Lang created himself , that manipulates thousands of mathematical calculations in the production of a “folding map” of a single creature. You could take an uncut square fold texture in to the model. You can also make 400 scales for a fish and you can make 50 stars for the American flag.
