And Ronald wanted to investigate more deeply.” #SPAGHETTI LASER SHOW CRACK MANUAL#“They did some manual tests, tried various things, and came up with an idea that when he twisted the spaghetti really hard and brought the ends together, it seemed to work and it broke into two pieces,” Dunkel said. They knew about Feynman’s kitchen experiment and wondered if there is a way to split spaghetti in two and if the break can be controlled. In the spring semester of 2015, the two students took a course in non-linear dynamics taught by Dunkel. “In any case, this has been a fun interdisciplinary project started and carried out by two brilliant and persistent students - who probably don’t want to see, break, or eat spaghetti for a while.” “It will be interesting to see whether and how twist could similarly be used to control the fracture dynamics of two-dimensional and three-dimensional materials,” said Dunkel. #SPAGHETTI LASER SHOW CRACK HOW TO#The team explained that this relatively trivial research can be applied to technical applications beyond culinary curiosities, such as understanding why crack formation happens and how to control fractures in other rod-like materials such as multifiber structures, engineered nanotubes or even microtubules in cells. The research team consisted of Professor Jörn Dunkel, associate professor of physical applied mathematics students Ronald Heisser and Vishal Palil, who spent hundreds of hours splitting noodles and co-authors Norbert Stoop, instructor of mathematics at MIT, and Emmanuel Villermaux of Université Aix Marseille. The paper published last week in the Proceedings of the National Academy of Sciences explains the results. The MIT researchers found that if the spaghetti is twisted and bent at the same time, the turns neutralize part of the vibrations that cause the pasta to split. This rapid movement causes vibrations that cause the pasta to ends up breaking into more pieces. When spaghetti is bent and split, the two halves return sharply to their straight form. In 2005 two French physicists – Basile Audoly and Sebastien Neukirch – working in their study "Fragmentation of Rods by Cascade Breaks," found that spaghetti sticks do not break in half because of vibrations that occur during the bending of the rods. Why spaghetti sticks break into more than two pieces perplexed even Richard Feynman, the 1965 Nobel Prize winner in Physics, who spent hours splitting pasta trying to come up with a solution. The spaghetti mystery has disturbed scientists for many years. ![]() A team of researchers at the Massachusetts Institute of Technology (MIT) found a solution to this problem. ![]()
