Origami or Paper Folding For The Frustrated!
 
 I would guess that many of you at one time or another have tried to
 fold a paper crane and see the wings flap.

 How about folding up a lot of panels, launching in a rocket to then
 unfold to make a big Fresnel lens for a space telescope.

 Robert J. Lang is an expert on Origami and ways mathematics can be
 used to design new and complicated ways you fold paper or even hard
 panels.
 
 Have you seen the 18 minute TED presentation?

 Origami, as Robert Lang describes it, is simple: "You take a creature,
 you combine it with a square, and you get an origami figure." But
 Lang's own description belies the technicality of his art; indeed, his
 creations inspire awe by sheer force of their intricacy. His
 repertoire 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 himself
 pioneered) that manipulates thousands of mathematical calculations in
 the production of a "folding map" of a single creature.
 
 The marriage of mathematics and origami harkens back to Lang's own
 childhood.  As a first-grader, Lang proved far too clever for
 elementary mathematics and quickly became bored, prompting his teacher
 to give him a book on origami. His acuity for mathematics would lead
 him to become a physicist at the California Institute of Technology,
 and the owner of nearly fifty patents on lasers and optoelectronics.
 Now a professional origami master, Lang practices his craft as both
 artist and engineer, one day folding the smallest of insects and the
 next the largest of space-bound telescope lenses.

 Interactive Rings Tessellation
 
 This demonstrates a rings-type origami tessellation. The left image is
 the crease pattern: mountain folds are solid black; valley folds are
 dashed magenta. The right side shows the folded form-the pattern you
 would get if you folded the crease pattern from translucent paper. The
 controls affect various parameters that define the design.

 So the next time you are frustrated by trying to make those creases
 and folds with a piece of paper, just think, you might be designing a
 large space structure to be launched in a small package. lofted to
 space on a rocket.  Maybe your kids can solve the problem. :-)

 The Fold-and-Cut Problem
 
 Take a piece of paper, fold it into any flat origami, and make one
 complete straight cut (i.e., a cut along a line). Now unfold the
 pieces, and see what you get. Are all shapes possible? Refering back
 to the original sheet of paper, what patterns of cuts can be achieved
 by this process?
 
 Several examples are now available for viewing and printing.

 Scientists developing origami spacecraft
 
 February 08, 2008 04:08pm
 
 A SPACECRAFT made of folded paper zooming through the skies may sound
 far-fetched, but Japanese scientists plan to launch paper planes from
 the International Space Station to see if they make it back to Earth.
 
 Earlier this week, the University of Tokyo researchers tested small,
 origami planes made of special paper for 30 seconds in 250 degrees
 Celsius heat and wind at seven times the speed of sound. The planes
 survived the wind tunnel test intact.
 
 The theory is that paper craft, being much lighter than space
 shuttles, may escape the worst of the friction and heat that much
 heavier space shuttles face on re-entry to the atmosphere.
 
 "Paper planes are extremely light so they slow down when the air is
 thin and can gradually descend," said Shinji Suzuki, a professor of
 aerospace engineering.
 
 Professor Suzuki said the technology might one day be used for
 unmanned spacecraft.
