Celestial Navigation Concepts

The video tutorial introduces a new Freshman course in the history of Science and Technology, focusing on the discovery of longitude and the determination of latitude. It discusses the historical context of these scientific challenges and explores celestial navigation techniques used by Lewis and Clark. The tutorial includes a practical exercise where students use 18th-century technology to measure latitude, culminating in a contest to see who can achieve the most accurate measurement.
