Shabbat Siren
In some Jewish communities, a Shabbat siren is sounded announcing the imminent onset of Shabbat and the required cessation of melacha at that time. Overview According to halakha, there are certain activities prohibited on Shabbat. Some Jewish communities sound a converted civil defense siren on Friday afternoon to announce that Shabbat will begin in order to warn and remind the local Jewish residents to stop doing such activities. In Jerusalem, the siren goes off 40 minutes before Shabbat. In other areas, including Brooklyn, the siren is sounded twice, once 15 minutes before Shabbat and a second time immediately before the start of shabbos. History The Talmud (Shabbat 35b) relates that on the eve of Shabbat, six shofar blasts (two series of Teki’a-Teru’a-Teki’a blows) were sounded to announce that Shabbat was approaching. Each blast represented a different act done to prepare for shabbos. The first blast told the workers in the fields to cease working and to retu ...

Gentile
Gentile () is a word that usually means "someone who is not a Jew". Other groups that claim Israelite heritage, notably Mormons, sometimes use the term ''gentile'' to describe outsiders. More rarely, the term is generally used as a synonym for ''heathen'' or ''pagan''. In some translations of the Quran, ''gentile'' is used to translate an Arabic word that refers to non-Jews and/or people not versed in or not able to read scripture. The English word ''gentile'' derives from the Latin word , meaning "of or belonging to the same people or nation" (). Archaic and specialist uses of the word ''gentile'' in English (particularly in linguistics) still carry this meaning of "relating to a people or nation." The development of the word to principally mean "non-Jew" in English is entwined with the history of Bible translations from Hebrew and Greek into Latin and English. Its meaning has also been shaped by Rabbinical Jewish thought and Christian theology which, from the 1st century ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Church Bell
A church bell in Christian architecture is a bell which is rung in a church for a variety of religious purposes, and can be heard outside the building. Traditionally they are used to call worshippers to the church for a communal service, and to announce the fixed times of daily Christian prayer, called the canonical hours, which number seven and are contained in breviaries. They are also rung on special occasions such as a wedding, or a funeral service. In some religious traditions they are used within the liturgy of the church service to signify to people that a particular part of the service has been reached. The ringing of church bells, in the Christian tradition, is also believed to drive out demons. The traditional European church bell ''(see cutaway drawing)'' used in Christian churches worldwide consists of a cup-shaped metal resonator with a pivoted clapper hanging inside which strikes the sides when the bell is swung. It is hung within a steeple or belltower of a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Loudspeakers In Mosques
Loudspeakers were invented in the early 20th century, and they were introduced in mosques in the 1930s, where they are used by a muezzin for the ''adhan'' ("call to prayer"), and sometimes for ''khutbah'' (sermons). Outdoor loudspeakers, usually mounted on tall minarets, are used five times a day for the call to prayer, beginning at dawn. Some mosques have loudspeakers that are powerful enough to be heard as far as 5 km (3 mi) away. In areas where more than one mosque is present, the loudspeaker sounds overlap one another, especially in the early morning when sounds are more clearly heard. Loudspeakers are sometimes also used inside mosques to deliver sermons or for prayer. The first known installation of a microphone–loudspeaker set occurred in 1936 in the Masjid Sultan in Singapore; it was reported that the summons to prayer could 'carry more than a mile'. Though some mosque attendees were sceptical of this new electric system, most believed it was necessary to em ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Adhan
Adhan ( ar, أَذَان ; also variously transliterated as athan, adhane (in French), azan/azaan (in South Asia), adzan (in Southeast Asia), and ezan (in Turkish), among other languages) is the Islamic call to public prayer (salah) in a mosque recited by a muezzin at prescribed times of the day. Adhan is recited very loudly from the mosque five times a day on most days and all day long during the religious holidays of Eid al-Fitr and Eid al-Adha, traditionally from the minaret. It is the first call summoning Muslims to enter the mosque for obligatory (''fard'') prayer (''salah''). A second call, known as the ''iqamah'', summons those within the mosque to line up for the beginning of the prayers. Only in Turkey, Ezan is voiced in five different styles at different times; saba, uşşak, hicaz, rast, segah. Terminology Adhān, Arabic for "announcement", from root ''ʾadhina'' meaning "to listen, to hear, be informed about", is variously transliterated in different cultures ...

Yeshiva
A yeshiva (; he, ישיבה, , sitting; pl. , or ) is a traditional Jewish educational institution focused on the study of Rabbinic literature, primarily the Talmud and halacha (Jewish law), while Torah and Jewish philosophy are studied in parallel. The studying is usually done through daily ''shiurim'' (lectures or classes) as well as in study pairs called '' chavrusas'' (Aramaic for 'friendship' or 'companionship'). ''Chavrusa''-style learning is one of the unique features of the yeshiva. In the United States and Israel, different levels of yeshiva education have different names. In the United States, elementary-school students enroll in a ''cheder'', post- bar mitzvah-age students learn in a ''metivta'', and undergraduate-level students learn in a ''beit midrash'' or ''yeshiva gedola'' ( he, ישיבה גדולה, , large yeshiva' or 'great yeshiva). In Israel, elementary-school students enroll in a ''Talmud Torah'' or ''cheder'', post-bar mitzvah-age students l ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Yeshiva Toras Emes
Yeshiva Toras Emes Kamenitz is an Orthodox boys school located at 1904 Avenue N in the Midwood section of Flatbush. History The school began as a pair of buildings housing the elementary grades, on 43rd street between 13th and 14th Avenue, and a separate building blocks away housing the high school, all in the lower end of Boro Park. Decades later, the 3 buildings were consolidated into a single building, a mile away. In the year 2000, the school relocated to its present location at 1904 Avenue N, Brooklyn, NY 11230. Student population The backgrounds of students changed from "the 1940s..." when "Rabbi Schwartz assumed leadership of Torah Emes." The growing presence of Jewish immigrants from the former Soviet Union within Brooklyn added to the yeshiva, and he helped with "the many challenges they faced." High school The high school's historical ''Kamenitz'' name has been augmented to include the name ''Joseph S. Gruss''. Elementary school References to the elementary school ...

Decibels
The decibel (symbol: dB) is a relative unit of measurement equal to one tenth of a bel (B). It expresses the ratio of two values of a Power, root-power, and field quantities, power or root-power quantity on a logarithmic scale. Two signals whose level (logarithmic quantity), levels differ by one decibel have a power ratio of 101/10 (approximately ) or root-power ratio of 10 (approximately ). The unit expresses a relative change or an absolute value. In the latter case, the numeric value expresses the ratio of a value to a fixed reference value; when used in this way, the unit symbol is often suffixed with letter codes that indicate the reference value. For example, for the reference value of 1 volt, a common suffix is "#Voltage, V" (e.g., "20 dBV"). Two principal types of scaling of the decibel are in common use. When expressing a power ratio, it is defined as ten times the Common logarithm, logarithm in base 10. That is, a change in ''power'' by a factor of 10 corresp ...
