The earliest stone tools have been little greater than a fractured rock, but approximately 75,000 years ago, stress flaking offered a approach to make a lot finer work. The distinction between science, engineering, and know-how just isn't all the time clear. Science is systematic knowledge of the bodily or material world gained through remark and experimentation.

In Goethe's Faust, Faust selling his soul to the devil in Đèn năng lượng mặt trời return for energy over the physical world can be often interpreted as a metaphor for the adoption of business technology. More lately, modern works of science fiction such as these by Philip K. Dick and William Gibson and movies such as Blade Runner and Ghost within the Shell project highly ambivalent or cautionary attitudes toward expertise's impression on human society and identification. Scientific advances and the discovery of latest concepts later allowed for powered flight and developments in medication, chemistry, physics, costestimator and engineering. The rise in expertise has led to skyscrapers and broad city areas whose inhabitants depend on motors to move them and their food supplies. Communication improved with the invention of the telegraph, telephone, radio and television. The late-19th and early-20th centuries saw a revolution in transportation with the invention of the airplane and car.
