Geophysics and geotechnical engineering

A number of years ago, M. King Hubbert, then a geophysicist with the Shell Development Corporation, stated that a problem in geophysical modeling always arises in scaling a physical process. He tried to make a case with the example of finite strength of a person's muscle. As the muscle diameter increases, so the example goes, the increase in lifting force lags. The principle is that geophysical dimensions of a process can be scaled directly but the gravitational and time dimensions cannot. In the converse of the muscle example, scaling of a geological process to the dimensions of a laboratory bench meets with large errors.
