The most-cited paper in theoretical particle physics in 2004 was "A large mass hierarchy from a small extra dimension" by Lisa Randall and Raman Sundrum, published in Physical Review Letters in 1999.
"It's funny to see how people react to it. Non-technical people steer wide and won't touch it, while engineers and designers, people you wouldn't think of as given to humor, will stand in front of it until it moves around or put a handkerchief on the wireless camera.
In 1998, theorists Lisa Randall and Raman Sundrum met in a coffee shop in Boston to discuss how extra dimensions of space would change the predictions of particle theories.
Deep in the Homestake Gold Mine in Lead, South Dakota, during the early 1970s, Ray Davis monitored a 100,000-gallon tank of perchloroethylene, a chlorine-rich dry-cleaning chemical.
Not only are neutrinos hard to catch, but they also change form as they travel through space. New experiments hope to understand their chameleonic nature.
