🔑 Key Concepts & Definitions

• Cotton Gin (invented by Eli Whitney in 1793): a machine that quickly separates cotton fibers from seeds, revolutionizing cotton production and increasing the demand for slavery (see impact on slavery in other sections).

• Interchangeable Parts (popularized by Eli Whitney in the late 18th century): standardized components that can be replaced individually, enabling mass production and easier repair of goods.

• Steam Power (developed during the late 18th and early 19th centuries): the use of steam engines to drive machinery, revolutionizing transportation and manufacturing, and facilitating the Industrial Revolution.

• Telegraphs (developed by Samuel Morse in the 1830s): devices that transmit messages over long distances using coded signals, transforming communication across the United States.

• Reapers (invented by Cyrus McCormick in 1831): mechanical harvesters that significantly increased the efficiency of grain harvesting, contributing to agricultural productivity.
