In this groundbreaking two-volume textbook first published in 1867, Lord
Kelvin and Peter Guthrie Tait offer a unified scientific explanation of
the physical world through the laws of energy. They defined much of what
today is considered physics, covering such realms as liquid motion,
instantaneous velocity, and the motion of a rigid body around a fixed
point. From simple movement to fluid dynamics the authors provide
readers with the necessary science and mathematics to describe complex
systems of motion. Irish scientist, engineer, and author LORD WILLIAM
THOMSON KELVIN (1824-1907) is considered an foundational thinker of
modern physics. He invented the Kelvin temperature scale and also helped
develop the first transatlantic telegraph cable. Scottish physicist
PETER GUTHRIE TAIT (1831-1901) was educated at Cambridge. Among his
writings is the scientific and religious text The Unseen Universe
(1901).
