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.

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.
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.

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.
The Steam Machines were in industrial use since 1712.
