Edwin Howard Armstrong (December 18, 1890 – January 31, 1954) was an American electrical engineer and inventor. He has been called "the most prolific and influential inventor in radio history". He invented the regenerative circuit while he was an undergraduate and patented it in 1914, followed by the super-regenerative circuit in 1922, and the superheterodyne receiver in 1918. Armstrong was also the inventor of modern frequency modulation (FM) radio transmission. 


 


Sir Joseph John "J. J." ThomsonOMFRS (18 December 1856 – 30 August 1940) was a British physicist. In 1897, Thomson showed that cathode rays were composed of a previously unknown negatively charged particle, and thus is credited with the discovery and identification of the electron. Thomson is also credited with finding the first evidence for isotopes of a stable (non-radioactive) element in 1913 as part of his exploration into the composition of canal rays (positive ions) and with the invention of the mass spectrometer. Thomson was awarded the 1906 Nobel Prize in Physics for the discovery of the electron and for his work on the conduction of electricity in gases.


 


He, in 1897, was the first to suggest that the fundamental unit was over 1000 times smaller than an atom, suggesting the subatomic particles now known as electronsThomson discovered this through his explorations on the properties of cathode raysHe called the particles "corpuscles", but later scientists preferred the name electron which had been suggested by George Johnstone Stoney in 1891, prior to Thomson's actual discovery.


 Steven Allan Spielberg (born December 18, 1946) is an American film director, screenwriter, producer, and business magnate. In a career of more than four decades, Spielberg's films have covered many themes and genres. Spielberg's early science-fiction and adventure films were seen as archetypes of modern Hollywood blockbuster filmmaking. In later years, his films began addressing humanistic issues such as the Holocaust, the transatlantic slave tradewar, and terrorism. He is considered one of the most popular and influential filmmakers in the history of cinema. He is also one of the co-founders of DreamWorks movie studio.


 


Perl is a family of high-levelgeneral-purposeinterpreteddynamic programming languages. The languages in this family include Perl 5 and Perl 6. Though Perl is not officially an acronym, there are various backronyms in use, such as: Practical Extraction and Reporting Language. Perl was originally developed by Larry Wall in 1987 as a general-purpose Unix scripting language to make report processing easier. The latest major stable revision of Perl 5 is 5.18, released in May 2013. Perl 6, which began as a redesign of Perl 5 in 2000, eventually evolved into a separate language


 


The Perl languages borrow features from other programming languages including Cshell scripting (sh), AWK, and sed. They provide powerful text processing facilities without the arbitrary data-length limits of many contemporary Unix commandline tools, facilitating easy manipulation of text files. Perl 5 gained widespread popularity in the late 1990s as a CGI scripting language, in part due to its parsing abilities.


 


In addition to CGI, Perl 5 is used for graphics programmingsystem administrationnetwork programming, finance, bioinformatics, and other applications. It is nicknamed "the Swiss Army chainsaw of scripting languages"because of its flexibility and power, and possibly also because of its "ugliness". In 1998, it was also referred to as the "duct tape that holds the Internet together", in reference to both its ubiquitous use as a glue language and its inelegance.


 


Larry Wall (born September 27, 1954) is a computer programmer and author, most widely known as the creator of the Perl programming language. Wall grew up in south Los Angeles and then Bremerton, Washingtonbefore starting higher education at Seattle Pacific University in 1976, majoring in chemistry and music and later Pre-med with a hiatus of several years working in the university's computing center before being graduated with a self-styled bachelor's degree in Natural and Artificial Languages. In 1987, on 18th of december; he released the first version of the Perl programming language.


 


Also in 1997,  on 18th December HTML 4.0 is published by the World Wide Web Consortium.
