John Bosco

Saint John Bosco (Italian: Giovanni Melchiorre Bosco; 16 August 1815 – 31 January 1888), popularly known as Don Bosco [ˈdɔm ˈbosko], was an Italian Roman Catholic priest, educator and writer of the 19th century. While working in Turin, where the population suffered many of the effects of industrialization and urbanization, he dedicated his life to the betterment and education of street children, juvenile delinquents, and other disadvantaged youth. He developed teaching methods based on love rather than punishment, a method that became known as the Salesian Preventive System. A follower of the spirituality and philosophy of Saint Francis de Sales, Bosco dedicated his works to him when he founded the Salesians of Don Bosco, based in Turin. Together with Maria Domenica Mazzarello, he founded the Institute of the Daughters of Mary Help of Christians, a religious congregation of nuns dedicated to the care and education of poor girls.

In 1876 Bosco founded a movement of laity, the Association of Salesian Cooperators, with the same educational mission to the poor. In 1875 he began to publish the Salesian Bulletin. The Bulletin has remained in continuous publication, and is currently published in 50 different editions and 30 languages.

Radio

Radio is the use of radio waves is to carry information, such as sound, by systematically modulating some property of electromagnetic energy waves transmitted through space, such as their amplitude, frequency, phase, or pulse width. When radio waves strike an electrical conductor, the oscillating fields induce an alternating current in the conductor. The information in the waves can be extracted and transformed back into its original form.

Radio systems need a transmitter to modulate (change) some property of the energy produced to impress a signal on it, for example using amplitude modulation or angle modulation (which can be frequency modulation or phase modulation). Radio systems also need an antenna to convert electric currents into radio waves, and vice versa. An antenna can be used for both transmitting and receiving. The electrical resonance of tuned circuits in radios allow individual stations to be selected. The electromagnetic wave is intercepted by a tuned receiving antenna. A radio receiver receives its input from an antenna and converts it into a form usable for the consumer, such as sound, pictures, digital data, measurement values, navigational positions, etc. Radio frequencies occupy the range from a 3 kHz to 300 GHz, although commercially important uses of radio use only a small part of this spectrum.
