modern technology in his origami, including using a laser cutter to help score paper for complex folds. Lang is recognized as one of the leading theorists of the mathematics of origami. He has developed ways to algorithmetize the design process for origami, and is the author of the proof of the completeness of the Huzita–Hatori axioms. Lang specializes in finding real-world applications for the various theories of origami he has developed. These included designing folding patterns for a German airbag manufacturer. He has worked with the Lawrence Livermore National Laboratory in Livermore, California, where a team is developing a powerful space telescope, with a 100 m (328 ft) lens in the form of a thin membrane. Lang was engaged by the team to develop a way to fit the tremendous lens, known as the Eyeglass, into a small rocket in such a way that the lens can be unfolded in space and will not suffer from any permanent marks or creases. Lang is the author or co-author of eight books and many articles on origami. Lang also designed the Google Doodle for Akira Yoshizawa's 101st birthday, which was used by Google on March 14, 2012. Awards and honors In 2012 he became a fellow of the American Mathematical Society.
