Old methods in science experiments came from alchemy where there was a futile quest for the philosopher’s stone which was believed to transform a base metal to gold. In the 17th century, such practices were depicted by several Dutch and Flemish paintings, though Holland still remained as the place where modern science was applied.
The way science become more logical as tons of experiments were conducted was portrayed in “An Experiment on a Bird in the Air Pump” which was by Joseph Wright of Derby in 1768.
A lot of science and engineering establishments and national art galleries display a variety of portraits of engineers, designers, and science researchers. Most of the time, the paintings feature the popular inventors and scientists while at work, during their time of brilliance or many years after they passed away.
