69 results about "Experimental system" patented technology

In scientific research, an experimental system is the physical, technical and procedural basis for an experiment or series of experiments. Historian of science Hans-Jörg Rheinberger defines an experimental system as: "A basic unit of experimental activity combining local, technical, instrumental, institutional, social, and epistemic aspects." Scientists (particularly laboratory biologists) and historians and philosophers of biology have pointed to the development and spread of successful experimental systems, such as those based on popular model organism or scientific apparatus, as key elements in the history of science, particularly since the early 20th century. The choice of an appropriate experimental system is often seen as critical for a scientist's long-term success, as experimental systems can be very productive for some kinds of questions and less productive for others, acquiring a sort of momentum that takes research in unpredicted directions.
