This exhibition at Vassar College's Palmer Gallery through March 6 explores the intuitive, creative side to scientific experiments and inventions. "Spark!" displays materials demonstrating the creative leap—featuring a serpent-shaped Renaissance horn, large prints of the moon taken from Paris in 1906, old medical charts, hand-colored bird slides, and many other devices, such as the Winogradsky Column (used to culture microorganisms), as well as sound diffusers, which manipulate the way sound moves throughout a concert hall. The exhibit is curated by Richard Jones, co-director of the Vassar College Artifacts Project. Vassar.edu.
