Physicists discover a different way to board a plane

Nature: Fermilab's Jason Steffen became so frustrated over the delays in boarding an aircraft that he decide to do something about it. He has applied a computational technique commonly used to map the movement of atoms and molecules to simulate how passengers move around a gridded space on an aircraft. According to his research the most common way airlines use to board passengers on an aircraft is mathematically, an extremely inefficient technique. Instead he suggests applying a strictly ordered optimal sequence that cuts boarding times by a factor of 7.
