What happens
This chapter reflects on the state of science at the close of the nineteenth century, contrasting the complacent belief that all great discoveries had been made with the burgeoning spirit of inquiry that would soon revolutionize human life. It highlights the limitations of past scientific methods, using the example of Henry Cavendish's determination of air composition and the overlooked element argon, and introduces the young Holsten, whose early experiments with fireflies and a spinthariscope foreshadow his future as a great chemist.
Themes in this chapter
Science and the Seeker Spirit
The chapter contrasts the limited scientific spirit of the 19th century with the growing multitude of seekers in the early 20th, exemplified by young Holsten's curiosity.
Technological Progress and Its Consequences
Discusses how past scientific inaccuracies (e.g., missing argon) held back progress, and hints at the coming revolution in chemistry that will transform life.
Characters to notice
- Young Holsten
Introduced as a fifteen-year-old prodigy with a 'savage appetite to understand,' studying fireflies and phosphorescence in Italy.
Key passages
“The great things are discovered,' wrote Gerald Brown in his summary of the nineteenth century. 'For us there remains little but the working out of detail.'”
Gerald Brown expressed the common late-19th-century view that all major discoveries had been made, leaving only minor refinements for future generations.
Illustrates the complacency that the chapter critiques.
“He was then only fifteen, but he was already distinguished as a mathematician and possessed by a savage appetite to understand.”
At just fifteen, Holsten was noted for his mathematical talent and an intense drive to comprehend the world.
Introduces young Holsten's character and his relentless curiosity.
