General relativity used to find optimal airplane boarding speed
(PHYSorg.com Mathematics)

A team of researchers from Western Norway University of Applied Sciences, Riga Technical University and Ben-Gurion University has created a mathematical model that can be used to predict boarding times for airplanes based on the boarding speed of individual passengers. In their paper published in the journal Physical Review E, the group describes using Lorentzian geometry to create their model, and what it showed.
