Berger begins by claiming that in nude art the “presence” of a man is that of an actor who asserts

Electronics engineering‚ [1] also referred to as electronic engineering[2][3] is an engineering discipline which uses the scientific knowledge of the behavior and effects of electrons to develop components‚ devices‚ systems‚ or equipment (as in electron tubes‚ transistors‚ integrated circuits‚ and printed circuit boards) that uses electricity as part of its driving force. Both terms denote a broad engineering field that encompasses many subfields including those that deal with power‚ instrumentation

MOLECULAR ELECTRONICS INTRODUCTION Molecular electronics (sometimes called moletronics) is a branch of applied physics which aims at using molecules as passive (e.g. resistive wires) or active (e.g. transistors) electronic components. The concept of molecular electronics has aroused much excitement both in science fiction and among scientists due to the prospect of size reduction in electronics offered by such minute components. It is an enticing alternative to extend Moore’s Law beyond the

Chapter three of Animal Wise centers mostly around the well-known African gray parrot named Alex. Virginia Morell went to Pepperberg’s lab at Brandeis University in Massachusetts and observed Alex’s daily routines. Morell got to experience the model/rival technique‚ which Pepperberg used to teach labels to Alex. The technique in its simplest form would go as such: Alex would be perched between two people. The first person would hold up an item like wood and would ask the second person what it is

In 1965‚ Dr. Gordon Moore working as the Director of R&D for Fairchild Semiconductor published a paper titled “Cramming more components onto integrated circuits”. In his paper‚ he discusses the future of electronics and how these “integrated circuits will lead to such wonders as home computers—or at least terminals connected to a central computer—automatic controls for automobiles‚ and personal portable communications equipment”. He also discusses how the rate in which the number of transistors
