Logos (UK /ˈloʊɡɒs/, /ˈlɒɡɒs/, or US /ˈloʊɡoʊs/; Greek: λόγος, from λέγω lego "I say") is an important term in western philosophy, psychology, rhetoric, and religion. It is a Greek word meaning "a ground", "a plea", "an opinion", "an expectation", "word", "speech", "account", "to reason", but it became a technical term in philosophy beginning with Heraclitus (ca. 535–475 BC), who used the term for a principle of order and knowledge.
Ancient Greek philosophers used the term in different ways. The sophists used the term to mean discourse, and Aristotle applied the term to refer to "reasoned discourse" or "the argument" in the field of rhetoric. The Stoic philosophers identified the term with the divine animating principle pervading the Universe. Under Hellenistic Judaism, Philo (c. 20 BC – AD 50) adopted the term into Jewish philosophy. The Gospel of John identifies the Logos, through which all things are made, as divine (theos), and further identifies Jesus Christ as the incarnate Logos. Although the term "Logos" is widely used in this Christian sense, in academic circles it often refers to the various ancient Greek uses, or to post-Christian uses within contemporary philosophy, Sufism, and the analytical psychology of Carl Jung.
In Christology, Logos (Greek: Λόγος logos, that is, "word", "discourse" or "reason" i.e., rationality or reasoning) is a name or title of Jesus Christ, seen as the pre-existent Second Person of a Trinitarian God. It has been important in endeavoring to establish the doctrine of the divinity and morality of Jesus Christ and his position as God the Son in the Trinity by Trinitarian theologians as set forth in the Chalcedonian Creed.
The concept derives from the opening of the Gospel of John, which is often simply translated into English as: "In the beginning was the Word, and the Word was with God, and the Word was God." In the translations, "word" is used for logos (λόγος), but in theological discourse, this is often left untranslated.
Christ as the logos
Christian theologians often consider John 1:1 to be a central text in their belief that Jesus is God, in connection with the idea that the Father, the Son, and the Holy Spirit are equals. Though only in this verse is Jesus referred to as the Word of God, the theme recurs throughout the Gospel of John with variations. Theologian N.T. Wright characterizes "Word" (logos) as being incomprehensible in human language. He claims that through belief the Logos will transform people with its judgment and mercy. According to Wright, John's view of the Incarnation, of the Word becoming flesh, strikes at the very root of what he terms "the liberal denial...of the idea of God becoming human...." His assessment is that when the "enfleshment" and speaking Word is removed from the center of Christian theology, all that is left is "a relativism whose only moral principle is that there are no moral principles, no words of judgment (because nothing is really wrong, except saying that things are wrong), no words of mercy (because you're all right as you are, so all you need is affirmation)."

Supersonic speed is a rate of travel of an object that exceeds the speed of sound (Mach 1). For objects traveling in dry air of a temperature of 20 °C (68 °F) at sea level, this speed is approximately 343.2 m/s, 1,125 ft/s, 768 mph, 667 knots, or 1,235 km/h. Speeds greater than five times the speed of sound (Mach 5) are often referred to as hypersonic. Flights during which only some parts of the air surrounding an object, such as the ends of rotor blades, reach supersonic speeds are called transonic. This occurs typically somewhere between Mach 0.8 and Mach 1.23.
Sounds are traveling vibrations in the form of pressure waves in an elastic medium. In gases, sound travels longitudinally at different speeds, mostly depending on the molecular mass and temperature of the gas, and pressure has little effect. Since air temperature and composition varies significantly with altitude, Mach numbers for aircraft may change despite a constant travel speed. In water at room temperature supersonic speed can be considered as any speed greater than 1,440 m/s (4,724 ft/s). In solids, sound waves can be polarized longitudinally or transversely and have even higher velocities.
Supersonic is a studio album by Korean singer Younha, released on July 03, 2012. While technically her fifth Korean album, it is fourth album as a whole, as referenced by the album title.
