Exponential beer froth decay – disputed

Arnd Leike of the University of Munich was awarded the 2002 Ig Noble Physics prize for demonstrating that beer froth obeys the mathematical Law of Exponential Decay. [Reference “Demonstration of the Exponential Decay Law Using Beer Froth,” Arnd Leike, European Journal of Physics, vol. 23, January 2002, pp. 21-26.] Since then, investigations into the decay […]
