Joseph Solomon Delmedigo
Joseph Solomon Delmedigo (or Del Medigo), also known as Yashar Mi-Qandia ( he, יש"ר מקנדיא) (16 June 1591 – 16 October 1655), was a rabbi, author, physician, mathematician, and music theorist. Born in Candia, Crete, a descendant of Elia del Medigo, he moved to Padua, Italy, studying medicine and taking classes with Galileo in astronomy. After graduating in 1613 he moved to Venice and spent a year in the company of Leon de Modena and Simone Luzzatto. From Venice he went back to Candia and from there started traveling in the near East, reaching Alexandria and Cairo. There he went into a public contest in mathematics against a local mathematician. From Egypt he moved to Istanbul, there he observed the comet of 1619. After Istanbul he wandered along the Karaite communities in Eastern Europe, finally arriving at Amsterdam in 1623. He died in Prague. Yet in his lifetime wherever he sojourned he earned his living as a physician and or teacher. His only known works are ''Eli ...

Hebrew Language
Hebrew (; ; ) is a Northwest Semitic language of the Afroasiatic language family. Historically, it is one of the spoken languages of the Israelites and their longest-surviving descendants, the Jews and Samaritans. It was largely preserved throughout history as the main liturgical language of Judaism (since the Second Temple period) and Samaritanism. Hebrew is the only Canaanite language still spoken today, and serves as the only truly successful example of a dead language that has been revived. It is also one of only two Northwest Semitic languages still in use, with the other being Aramaic. The earliest examples of written Paleo-Hebrew date back to the 10th century BCE. Nearly all of the Hebrew Bible is written in Biblical Hebrew, with much of its present form in the dialect that scholars believe flourished around the 6th century BCE, during the time of the Babylonian captivity. For this reason, Hebrew has been referred to by Jews as '' Lashon Hakodesh'' (, ) since an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Don Harrán
Don Harran (also spelled Harrán, ebrew דון חרן 22 April 1936 – 15 June 2016) was professor of musicology at the Hebrew University of Jerusalem. Biography Born Donald Lee Hersh in Cambridge, Massachusetts, Don Harrán did his undergraduate work at Yale University, majoring in French literature (B.A. magna cum laude, 1957), and pursued graduate studies in musicology, mainly under Edward Lowinsky and, as dissertation advisor, Joseph Kerman, at the University of California at Berkeley (M.A., 1959; Ph.D., 1963).

Hippocrates
Hippocrates of Kos (; grc-gre, Ἱπποκράτης ὁ Κῷος, Hippokrátēs ho Kôios; ), also known as Hippocrates II, was a Greek physician of the classical period who is considered one of the most outstanding figures in the history of medicine. He is traditionally referred to as the "Father of Medicine" in recognition of his lasting contributions to the field, such as the use of prognosis and clinical observation, the systematic categorization of diseases, or the formulation of humoral theory. The Hippocratic school of medicine revolutionized ancient Greek medicine, establishing it as a discipline distinct from other fields with which it had traditionally been associated (theurgy and philosophy), thus establishing medicine as a profession. However, the achievements of the writers of the Hippocratic Corpus, the practitioners of Hippocratic medicine, and the actions of Hippocrates himself were often conflated; thus very little is known about what Hippocrates actually t ...

Isaac Luria
Isaac ben Solomon Luria Ashkenazi (1534Fine 2003, p24/ref> – July 25, 1572) ( he, יִצְחָק בן שלמה לוּרְיָא אשכנזי ''Yitzhak Ben Sh'lomo Lurya Ashkenazi''), commonly known in Jewish religious circles as "Ha'ARI" (meaning "The Lion"), "Ha'ARI Hakadosh" (the holy ARI) or "ARIZaL" (the ARI, of Blessed Memory ( Zikhrono Livrakha)), was a leading rabbi and Jewish mystic in the community of Safed in the Galilee region of Ottoman Syria, now Israel/Palestine 1948. He is considered the father of contemporary Kabbalah, his teachings being referred to as Lurianic Kabbalah. While his direct literary contribution to the Kabbalistic school of Safed was extremely minute (he wrote only a few poems), his spiritual fame led to their veneration and the acceptance of his authority. The works of his disciples compiled his oral teachings into writing. Every custom of Luria was scrutinized, and many were accepted, even against previous practice. Luria died at Safed, Damascu ...

Kabbalah
Kabbalah ( he, קַבָּלָה ''Qabbālā'', literally "reception, tradition") is an esoteric method, discipline and Jewish theology, school of thought in Jewish mysticism. A traditional Kabbalist is called a Mekubbal ( ''Məqūbbāl'' "receiver"). The definition of Kabbalah varies according to the tradition and aims of those following it, from its origin in medieval Judaism to its later adaptations in Western esotericism (Christian Kabbalah and Hermetic Qabalah). Jewish Kabbalah is a set of esoteric teachings meant to explain the relationship between the unchanging, eternal God in Judaism, God—the mysterious ''Ein Sof'' (, ''"The Infinite"'')—and the mortal, finite universe (God's Genesis creation narrative, creation). It forms the foundation of Mysticism, mystical religious interpretations within Judaism. List of Jewish Kabbalists, Jewish Kabbalists originally developed their own transmission of Primary texts of Kabbalah, sacred texts within the realm of Jewish traditio ...

Almagest
The ''Almagest'' is a 2nd-century Greek-language mathematical and astronomical treatise on the apparent motions of the stars and planetary paths, written by Claudius Ptolemy ( ). One of the most influential scientific texts in history, it canonized a geocentric model of the Universe that was accepted for more than 1,200 years from its origin in Hellenistic Alexandria, in the medieval Byzantine and Islamic worlds, and in Western Europe through the Middle Ages and early Renaissance until Copernicus. It is also a key source of information about ancient Greek astronomy. Ptolemy set up a public inscription at Canopus, Egypt, in 147 or 148. N. T. Hamilton found that the version of Ptolemy's models set out in the ''Canopic Inscription'' was earlier than the version in the ''Almagest''. Hence the ''Almagest'' could not have been completed before about 150, a quarter-century after Ptolemy began observing. Names The name comes from Arabic ', with ' meaning "the", and ''magesti'' bei ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Consonance And Dissonance
In music, consonance and dissonance are categorizations of simultaneous or successive Sound, sounds. Within the Western tradition, some listeners associate consonance with sweetness, pleasantness, and acceptability, and dissonance with harshness, unpleasantness, or unacceptability, although there is broad acknowledgement that this depends also on familiarity and musical expertise. The terms form a structural dichotomy in which they define each other by mutual exclusion: a consonance is what is not dissonant, and a dissonance is what is not consonant. However, a finer consideration shows that the distinction forms a gradation, from the most consonant to the most dissonant. In casual discourse, as German composer and music theorist Paul Hindemith stressed, "The two concepts have never been completely explained, and for a thousand years the definitions have varied". The term ''sonance'' has been proposed to encompass or refer indistinctly to the terms ''consonance'' and ''dissonance' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Interval (music)
In music theory, an interval is a difference in pitch between two sounds. An interval may be described as horizontal, linear, or melodic if it refers to successively sounding tones, such as two adjacent pitches in a melody, and vertical or harmonic if it pertains to simultaneously sounding tones, such as in a chord. In Western music, intervals are most commonly differences between notes of a diatonic scale. Intervals between successive notes of a scale are also known as scale steps. The smallest of these intervals is a semitone. Intervals smaller than a semitone are called microtones. They can be formed using the notes of various kinds of non-diatonic scales. Some of the very smallest ones are called commas, and describe small discrepancies, observed in some tuning systems, between enharmonically equivalent notes such as C and D. Intervals can be arbitrarily small, and even imperceptible to the human ear. In physical terms, an interval is the ratio between two sonic freq ...

Resonance
Resonance describes the phenomenon of increased amplitude that occurs when the frequency of an applied periodic force (or a Fourier component of it) is equal or close to a natural frequency of the system on which it acts. When an oscillating force is applied at a resonant frequency of a dynamic system, the system will oscillate at a higher amplitude than when the same force is applied at other, non-resonant frequencies. Frequencies at which the response amplitude is a relative maximum are also known as resonant frequencies or resonance frequencies of the system. Small periodic forces that are near a resonant frequency of the system have the ability to produce large amplitude oscillations in the system due to the storage of vibrational energy. Resonance phenomena occur with all types of vibrations or waves: there is mechanical resonance, orbital resonance, acoustic resonance, electromagnetic resonance, nuclear magnetic resonance (NMR), electron spin resonance (ESR) and reso ...
