SUMMARY

Jonathan Swift accurately described the two moons of Mars, Phobos and Deimos, in his 1726 work "Gulliver's Travels," detailing their sizes and rotational speeds over a century before their discovery. This remarkable foresight raises questions about the methods he may have employed to predict such astronomical phenomena. The discussion highlights the significance of Swift's insights in the context of early scientific understanding and imagination.

PREREQUISITES
  • Understanding of early 18th-century literature and its scientific context
  • Basic knowledge of astronomy, specifically planetary moons
  • Familiarity with the history of Mars exploration
  • Awareness of the scientific methods used in predicting celestial bodies
NEXT STEPS
  • Research the historical context of "Gulliver's Travels" and its scientific implications
  • Explore the discovery of Phobos and Deimos and their characteristics
  • Investigate early astronomical theories and predictions about celestial bodies
  • Learn about the methods used in predicting the orbits and sizes of moons
USEFUL FOR

Literary scholars, historians of science, astronomers, and anyone interested in the intersection of literature and scientific prediction.

In Gulliver's Travels Jonathan Swift described the two moons of Mars, Phobos and Deimos, giving their exact size and speeds of rotation. He did this more than 100 years before either moon was discovered.

granted this is true - how would one even predict such a thing?
