Research
Due to their ubiquitousness in nature gravity currents have been and still are intensely studied in laboratories all over the world.
The first mathematical study of the propagation of gravity currents can be attributed to T. B. Benjamin. Observations of intrusions and collisions between fluids of differing density were made well before T. B. Benjamin's study, see for example by M. B. Abbot or D. I. H. Barr.
J. E. Simpson from the Department of Applied Mathematics and Theoretical Physics of Cambridge University in the UK has carried out longstanding research on gravity currents and issued a multitude of papers on the subject. He published an article in 1982 for Annual Review of Fluid Mechanics which summarises the state of research in the domain of gravity currents at the time. Although now nearly 30 years old, his article forms a good introduction to the subject. Simpson also published a more detailed book on the topic.

Famous quotes containing the word research:
“It is a good morning exercise for a research scientist to discard a pet hypothesis every day before breakfast. It keeps him young.”
—Konrad Lorenz (1903–1989)
“If politics is the art of the possible, research is surely the art of the soluble. Both are immensely practical-minded affairs.”
—Peter B. Medawar (1915–1987)
“The working woman may be quick to see any problems with children as her fault because she isn’t as available to them. However, the fact that she is employed is rarely central to the conflict. And overall, studies show, being employed doesn’t have negative effects on children; carefully done research consistently makes this clear.”
—Grace Baruch (20th century)
