Ernst G. Strauss on 'the friendship of A. EInstein and Kurt Gödel ✍️
The one man who was, during the last years, certainly by far Einstein's best friend, and in some ways strangely resembled him most, was Kurt Gödel, The great logician. They were very different in almost every personal way — Einstein gregarious, happy, full of laughter and common sense, and Gödel extremely solemn, very serious, quite solitary, and distrustful of common sense as a means of arriving at the truth. But they shared a fundamental quality: both went directly and wholeheartedly to the questions at the very center of things.

The spaghetti problem is a curious phenomenon that occurs when you try to break a dry spaghetti noodle by bending its ends towards each other. Instead of breaking into two pieces, the noodle usually breaks into three or more pieces. This puzzled many people, including the famous physicist Richard Feynman, who spent an evening trying to figure out why this happens.
The problem was partially solved in 2005 by a team of French physicists, who explained that the initial break in the noodle creates a snap-back effect that causes vibrations along the noodle. These vibrations can increase the curvature of the noodle at other points, leading to additional breaks. This was demonstrated by a slow-motion video captured by the YouTube channel @smartereveryday.
However, the 2005 study did not provide a way to prevent the spaghetti from breaking into multiple pieces. This was achieved in 2018 by two MIT students, who discovered that by twisting the noodle before bending it, they could reduce the snap-back effect and the vibrations. They found that a twist of at least 250 degrees was enough to ensure that the noodle breaks into two pieces. This was also verified by experiments and computer simulations.
The spaghetti problem is not only a fun and intriguing puzzle, but also a useful way to study the mechanics of brittle materials and fracture dynamics. It may have applications in engineering, medicine, and nanotechnology.
