The Great Albert Einstein`s Opinion

• A Theory is more impressive

– the greater the simplicity of its premises is,

– the more different kinds of things it relates,

– and the more extended is its area of applicability.

Therefore, the deep impression which Classical Thermodynamics made upon me.

It is only physical theory of universal content concerning which I am convinced that , Within the framework of the applicability of its basic concepts, it will never be overthrown.

Historical Development in Steam Generators

FIRE, FLAME and TORCH

• Fire is a discovery rather than an invention.

• Homo erectus probably discovered fire by accident.

• Fire was most likely given to man as a 'gift from the heavens' when a bolt of lightning struck a tree or a bush, suddenly starting it on fire.

• The flaming touch and the campfire probably constituted early man's first use of 'artificial' lighting.

• As early as 400,000 BC, fire was kindled in the caves of Peking man.

• Prehistoric man, used primitive lamps to illuminate his cave.

• Various Oils were used as fuels.
