Norbert Wiener - Cybernetics




Norbert Wiener invented the field of cybernetics and conceptualized the thinking that  computer technology  extends human capabilities.

Norbert Wiener was born on November 26, 1894, and received his Ph.D. in Mathematics from Harvard University at the age of 18 for a thesis on mathematical logic.

During World War II, Wiener worked on guided missile technology, and observed  how the feedback principle was being used  when a missile changes its flight in response to its current position and direction. He also noticed that the feedback principle was also a key feature of life forms from the simplest plants to the most complex animals and they  change their actions in response to their environment. Wiener developed this concept into the field of cybernetics, concerning the combination of man and electronics. The book on Cybernetics was published in 1948.

Waht is Mohr's pinchcock burette?



A buret or burette is glass tube that allows delivery of a measured quantity of liquid. It is used in laboratory equipments. It was developed by Karl Friedrich Mohr using a pin on a rubber tube. The pinching action of the pin on the tube allowed the experimenter to deliver liquids drop by drop by and see the scale on the glass tube to determine the quantity of the  liquid delivered.

In the present day burets, the pinching pin is replaced by glass valve that allows liquid to flow in one position and stops the flow in other positions.

Read for more detail on it.

Higg's Boson - Research Papers - Bibliography



Although they are still hedging a bit, physicists at CERN, the European Organization for Nuclear Research, announced on 4th July 20120,  that they had found the long-sought Higgs boson.
