Surgical instrument. A surgical instrument is a medical device for performing specific actions or carrying out desired effects during a surgery or operation, such as modifying biological tissue, or to provide access for viewing it. [1] Over time, many different kinds of surgical instruments and tools have been invented.
The history of technology is the history of the invention of tools and techniques by humans. Technology includes methods ranging from simple stone tools to the complex genetic engineering and information technology that has emerged since the 1980s. The term technology comes from the Greek word techne, meaning art and craft, and the word logos ...
In 1904, John Ambrose Fleming, the first professor of electrical Engineering at University College London, invented the first radio tube, the diode. Then, in 1906, Robert von Lieben and Lee De Forest independently developed the amplifier tube, called the triode. Electronics is often considered to have begun with the invention of the diode.
Modern surface-mount electronic components on a printed circuit board, with a large integrated circuit at the top. Electronics is a scientific and engineering discipline that studies and applies the principles of physics to design, create, and operate devices that manipulate electrons and other electrically charged particles.
The Bulfinch Building, home of the Ether Dome. Throughout recorded history, attempts at producing a state of general anesthesia can be traced back to the writings of ancient Sumerians, Babylonians, Assyrians, Egyptians, Indians, and Chinese.

William Sturgeon invented the electromagnet in 1825. [19] Electromagnets were then used in the first practical engineering application of electricity by William Fothergill Cooke and Charles Wheatstone who co-developed a telegraph system that used a number of needles on a board which were moved to point to letters of the alphabet. A five needle ...
