"The situation in all science is that an excellent, well done experimental measurement is the "gold standard" to which all theories and models have to be compared. There are many examples in science in which a well done experiment showed the problems and errors in theory, and theory had to be redone."

"The principal reason experimental work is to be highly prized, is that experiments are the only way to recognize the physical world."

"Modelling has its place, but only for time and space scales unapproachable by experiment, or as a correlation tool to connect the dots of experimental measurement."

"Without making the measurements, one can hardly teach important aspects of the technique and extend the methods to new systems."

"There will be no time to come where experimental data will be superfluous. Focusing on modeling is definitely needed, but the more we focus on modeling, the more our needs to experimental measurements will be growing. "
