Historical Events tagged with "experiments"
Turns out history loves a label—battles, breakthroughs, and the occasional disaster, all neatly tagged for your browsing pleasure. Because sometimes you just need every weird invention in one place.
Presentation of the Franck-Hertz Experiment
In a pivotal presentation to the German Physical Society, physicists James Franck and Gustav Hertz detailed their groundbreaking experiment demonstrating energy quantization in atoms. Conducted in 1913, their experiments provided profound insights into atomic structure and paved the way for advancements in quantum mechanics. With meticulous methods, Franck and Hertz showcased how electrons absorbed energy, resulting in observable ionization. This work significantly influenced later developments in both theoretical and practical physics.

Alexis St. Martin was accidentally shot in the stomach at a fort in Michigan. The bullet left a significant wound, which did not heal properly, leaving an opening into his stomach. This unusual situation attracted the attention of William Beaumont, a military surgeon, who recognized the opportunity to study human digestion in real-time. His experiments with St. Martin, who became a patient and collaborator, led to extensive research on digestive processes and human physiology.

British scientist Joseph Priestley identified oxygen gas while experimenting with a burning candle in a closed container. His experiments took place in Birmingham, England, where he cooled the gas produced and noted its unique properties. Priestley's work corroborated earlier findings by German-Swedish chemist Carl Wilhelm Scheele, who had isolated oxygen gas several years prior, though his discoveries were not widely recognized at the time. Priestley’s experiments contributed to a foundational understanding of gases and combustion, greatly influencing future scientific research.

Otto von Guericke finalized his significant manuscript, 'Experimenta Nova (ut vocantur) Magdeburgica de Vacuo Spatio', where he vividly narrated his groundbreaking experiments on vacuum and electrostatic phenomena. Through rigorous experiments, he notably illustrated the absence of air and its effects, providing essential proofs of his theories. His work contributed to the understanding of atmospheric pressure and electrostatic forces, thereby influencing future scientific inquiries into these fields. This publication marked a notable advancement in experimental science and philosophy.
