An entertaining mathematical exploration of the heat equation and
its role in the triumphant development of the trans-Atlantic
telegraph cable Heat, like gravity, shapes nearly every aspect of
our world and universe, from how milk dissolves in coffee to how
molten planets cool. The heat equation, a cornerstone of modern
physics, demystifies such processes, painting a mathematical
picture of the way heat diffuses through matter. Presenting the
mathematics and history behind the heat equation, Hot Molecules,
Cold Electrons tells the remarkable story of how this foundational
idea brought about one of the greatest technological advancements
of the modern era. Paul Nahin vividly recounts the heat equation's
tremendous influence on society, showing how French mathematical
physicist Joseph Fourier discovered, derived, and solved the
equation in the early nineteenth century. Nahin then follows
Scottish physicist William Thomson, whose further analysis of
Fourier's explorations led to the pioneering trans-Atlantic
telegraph cable. This feat of engineering reduced the time it took
to send a message across the ocean from weeks to minutes. Readers
also learn that Thomson used Fourier's solutions to calculate the
age of the earth, and, in a bit of colorful lore, that writer
Charles Dickens relied on the trans-Atlantic cable to save himself
from a career-damaging scandal. The book's mathematical and
scientific explorations can be easily understood by anyone with a
basic knowledge of high school calculus and physics, and MATLAB
code is included to aid readers who would like to solve the heat
equation themselves. A testament to the intricate links between
mathematics and physics, Hot Molecules, Cold Electrons offers a
fascinating glimpse into the relationship between a formative
equation and one of the most important developments in the history
of human communication.
