Description:
The most exciting and significant episode of scientific progress is the
development of thermodynamics and electrodynamics in the 19th century
and early 20th century. The nature of heat and temperature was recognized,
the conservation of energy was discovered, and the realization that mass
and energy are equivalent provided a new fuel, – and unlimited power.
Much of this occurred in unison with the rapid technological advance
provided by the steam engine, the electric motor, internal combustion
engines, refrigeration and the rectification processes of the chemical
industry. The availability of cheap power and cheap fuel has had its impact
on society: Populations grew, the standard of living increased, the environment
became clean, traffic became easy, and life expectancy was raised.
Knowledge fairly exploded. The western countries, where all this happened,
gained in power and influence, and western culture – scientific culture –
spread across the globe, and is still spreading.
