Electroscope experiment, 19th century
Electroscope experiment. This simple version of an electroscope, designed to detect electric charge, is described as a glass flask with a stopper containing a metal rod. At the upper end of the rod (outside the flask) is mounted a ball. At the other end (inside the flask) strips of aluminium foil (or other lightweight metal) are mounted on a hook. When an electric charge is brought near the electroscope, the foil strips move apart or stick together. Here, the charge is static electricity from the crinkled paper at top. Artwork from the seventh volume (first period of 1891) of the French popular science weekly La Science Illustree

EDITORS COMMENTS
This print showcases an intriguing electroscope experiment from the 19th century. The image depicts a simple version of this device, designed to detect electric charge. A glass flask with a stopper contains a metal rod, while at the upper end of the rod (outside the flask) sits a ball. Inside the flask, strips of lightweight aluminium foil are mounted on a hook. When an electric charge is brought near the electroscope, these foil strips either move apart or stick together. In this particular scene, static electricity emanates from crinkled paper placed atop the apparatus. The artwork originates from La Science Illustree, a renowned French popular science weekly published in 1891. The photo evokes nostalgia for bygone scientific exploration and discovery during that era. It captures both the beauty and simplicity of early electrical experiments conducted by dedicated individuals seeking to unravel nature's mysteries. This historical snapshot not only serves as a visual testament to human curiosity but also highlights how technology has evolved over time. It reminds us of our continuous quest for knowledge and understanding in fields such as physics and electrostatics. With its meticulous attention to detail and monochromatic aesthetic, this print transports viewers back to an age when experimentation was at its peak—a timeless reminder that even small steps can lead to groundbreaking discoveries in science.
