Steam, The origin of Scientific Industrial
Civilization.

• Trace the origin of steam.
• Think about the impact of Steam on Science.
• Enumerate the impact of steam on Technology.
• Appreciate the role of steam in industrial world.

The Philosophy of Steam -- Mill

• There are many features which characterize this
  progressive economical movement of civilized
  nations.
• The best of the best feature which excites
  attention What is it?
• This is the feature which intimately connected
  with the phenomena of production
• This is the perpetual.
• The unlimited growth of man's power over Nature
  so far as human foresight can extend.

• Human being is a WEAK Animal
• Yet dominates the GLOBE !?!?!?!
• Human being has ability to provide power,
  
• set LIMITS to the rate of growth of
  Civilization.

11
The Philosophy of Steam -- Mill

• Our knowledge of the properties and laws of
  physical objects shows no sign of approaching its
  ultimate boundaries!!!!!
• It is advancing more rapidly, and in a greater
  number of directions at once, than in any
  previous age or generation.
• Affording such frequent glimpses of unexplored
  fields beyond as to justify the belief that our
  acquaintance with Nature is still almost in its
  infancy.

12
Origin of Steam Basis of Scientific
Technological Research

• Denis Papin, while working at Huygens and of
  Boyle, started to be interested in the vapor.
• Several geniuses of science tried before him to
  try out an unspecified machine which would run on
  the vapor, but their efforts were useless.
• It is into 1707 that Denis Papin made his first
  great realization the boat with vapor.
• This superb invention brought much controversy
  near the boatmen, who destroyed the ship.

13
The Boiler

• Boilers are accepted equipment of everyday life.
• A prime device which connects natural resources
  and human-made facilities.
• A fire
• A furnace.
• A boiler ..
• A Steam generator.

14
The Steam Machines were in industrial use since
1712.
Establishment of the first and second laws of
thermodynamics by Clausius, Kelvin et al.,
occurred in 1855!!!
15
This Led to Formulation of Greatest Science .

• Thermodynamics
