Alarm Clock
An alarm clock (or sometimes just an alarm) is a clock that is designed to alert an individual or group of individuals at a specified time. The primary function of these clocks is to awaken people from their night's sleep or short naps; they are sometimes used for other reminders as well. Most use sound; some use light or vibration. Some have sensors to identify when a person is in a light stage of sleep, in order to avoid waking someone who is deeply asleep, which causes tiredness, even if the person has had adequate sleep. To turn off the sound or light, a button or handle on the clock is pressed; most clocks automatically turn off the alarm if left unattended long enough. A classic analog alarm clock has an extra hand or inset dial that is used to specify the time at which the alarm will ring. Alarm clocks are also used in mobile phones, watches, and computers. Many alarm clocks have radio receivers that can be set to start playing at specified times, and are known as ''clock ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

1 (one, unit, unity) is a number representing a single or the only entity. 1 is also a numerical digit and represents a single unit of counting or measurement. For example, a line segment of ''unit length'' is a line segment of length 1. In conventions of sign where zero is considered neither positive nor negative, 1 is the first and smallest positive integer. It is also sometimes considered the first of the infinite sequence of natural numbers, followed by 2, although by other definitions 1 is the second natural number, following 0. The fundamental mathematical property of 1 is to be a multiplicative identity, meaning that any number multiplied by 1 equals the same number. Most if not all properties of 1 can be deduced from this. In advanced mathematics, a multiplicative identity is often denoted 1, even if it is not a number. 1 is by convention not considered a prime number; this was not universally accepted until the mid-20th century. Additionally, 1 is the s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Plato
Plato ( ; grc-gre, Πλάτων ; 428/427 or 424/423 – 348/347 BC) was a Greek philosopher born in Athens during the Classical period in Ancient Greece. He founded the Platonist school of thought and the Academy, the first institution of higher learning on the European continent. Along with his teacher, Socrates, and his student, Aristotle, Plato is a central figure in the history of Ancient Greek philosophy and the Western and Middle Eastern philosophies descended from it. He has also shaped religion and spirituality. The so-called neoplatonism of his interpreter Plotinus greatly influenced both Christianity (through Church Fathers such as Augustine) and Islamic philosophy (through e.g. Al-Farabi). In modern times, Friedrich Nietzsche diagnosed Western culture as growing in the shadow of Plato (famously calling Christianity "Platonism for the masses"), while Alfred North Whitehead famously said: "the safest general characterization of the European philosophica ...

Gaza City
Gaza (;''The New Oxford Dictionary of English'' (1998), , p. 761 "Gaza Strip /'gɑːzə/ a strip of territory in Palestine, on the SE Mediterranean coast including the town of Gaza...". ar, غَزَّة ', ), also referred to as Gaza City, is a Palestinian city in the Gaza Strip, with a population of 590,481 (in 2017), making it the largest city in the State of Palestine. Inhabited since at least the 15th century BCE, Gaza has been dominated by several different peoples and empires throughout its history. The Philistines made it a part of their pentapolis after the Ancient Egyptians had ruled it for nearly 350 years. Under the Roman Empire Gaza experienced relative peace and its port flourished. In 635 CE, it became the first city in Palestine to be conquered by the Muslim Rashidun army and quickly developed into a center of Islamic law. However, by the time the Crusaders invaded the country starting in 1099, Gaza was in ruins. In later centuries, Gaza experienced sever ...

Striking Clock
A striking clock is a clock that sounds the hours audibly on a bell or gong. In 12-hour striking, used most commonly in striking clocks today, the clock strikes once at 1:00 am, twice at 2:00 am, continuing in this way up to twelve times at 12:00 mid-day, then starts again, striking once at 1:00 pm, twice at 2:00 pm, up to twelve times at 12:00 midnight. The striking feature of clocks was originally more important than their clock faces; the earliest clocks struck the hours, but had no dials to enable the time to be read. The development of mechanical clocks in 12th century Europe was motivated by the need to ring bells upon the canonical hours to call the community to prayer. The earliest known mechanical clocks were large striking clocks installed in towers in monasteries or public squares, so that their bells could be heard far away. Though an early striking clock in Syria was a 12-hour clock, many early clocks struck up to 24 strokes, particularly in It ...

Procopius Of Gaza
Procopius of Gaza ( 465–528 AD) was a Christian sophist and rhetorician, one of the most important representatives of the famous school of his native place.Vikan, Gary, Alexander Kazhdan, and Zvi 'Uri Ma῾oz. "Gaza." In ''The Oxford Dictionary of Byzantium''. Oxford University Press, 1991. Here he spent nearly the whole of his life teaching and writing and took no part in the theological movements of his time. The little that is known of him is to be found in his letters and the ''encomium'' by his pupil and successor Choricius. He was the author of numerous rhetorical and theological works. Of the former, his panegyric on the emperor Anastasius alone is extant; the description of the Hagia Sophia and the monody on its partial destruction by an earthquake are spurious. His letters (162 in number), addressed to persons of rank, friends, and literary opponents, throw valuable light upon the condition of the sophistical rhetoric of the period and the character of the writer.

Christ
Jesus, likely from he, יֵשׁוּעַ, translit=Yēšūaʿ, label= Hebrew/Aramaic ( AD 30 or 33), also referred to as Jesus Christ or Jesus of Nazareth (among other names and titles), was a first-century Jewish preacher and religious leader; he is the central figure of Christianity, the world's largest religion. Most Christians believe he is the incarnation of God the Son and the awaited Messiah (the Christ) prophesied in the Hebrew Bible. Virtually all modern scholars of antiquity agree that Jesus existed historically. Research into the historical Jesus has yielded some uncertainty on the historical reliability of the Gospels and on how closely the Jesus portrayed in the New Testament reflects the historical Jesus, as the only detailed records of Jesus' life are contained in the Gospels. Jesus was a Galilean Jew who was circumcised, was baptized by John the Baptist, began his own ministry and was often referred to as "rabbi". Jesus debated with fe ...

Cassiodorus
Magnus Aurelius Cassiodorus Senator (c. 485 – c. 585), commonly known as Cassiodorus (), was a Roman statesman, renowned scholar of antiquity, and writer serving in the administration of Theodoric the Great, king of the Ostrogoths. ''Senator'' was part of his surname; not his rank. He also founded a monastery, Vivarium, where he spent the last years of his life. Life Cassiodorus was born at Scylletium, near Catanzaro in Calabria, Italy. Some modern historians speculate that his family was of Syrian origin based on his Greek name. His ancestry included some of the most prominent ministers of the state extending back several generations. His great-grandfather held a command in the defense of the coasts of southern Italy from Vandal sea-raiders in the middle of the fifth century; his grandfather appears in a Roman embassy to Attila the Hun, and his father (who bore the same name) served as '' comes sacrarum largitionum'' and '' comes rerum privatarum'' to Odovacer and as ...

Late Antiquity
Late antiquity is the time of transition from classical antiquity to the Middle Ages, generally spanning the 3rd–7th century in Europe and adjacent areas bordering the Mediterranean Basin. The popularization of this periodization in English has generally been credited to historian Peter Brown (historian), Peter Brown, after the publication of his seminal work ''The World of Late Antiquity (1971), The World of Late Antiquity'' (1971). Precise boundaries for the period are a continuing matter of debate, but Brown proposes a period between the 3rd and 8th centuries AD. Generally, it can be thought of as from the end of the Roman Empire's Crisis of the Third Century (235–284) to the early Muslim conquests (622–750), or as roughly contemporary with the Sasanian Empire (224–651). In the West its end was earlier, with the start of the Early Middle Ages typically placed in the 6th century, or earlier on the edges of the Western Roman Empire. The Roman Empire underwent considerable ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vitruv
Vitruvius (; c. 80–70 BC – after c. 15 BC) was a Roman architect and engineer during the 1st century BC, known for his multi-volume work entitled ''De architectura''. He originated the idea that all buildings should have three attributes: , , and ("strength", "utility", and "beauty"). These principles were later widely adopted in Roman architecture. His discussion of perfect proportion in architecture and the human body led to the famous Renaissance drawing of the '' Vitruvian Man'' by Leonardo da Vinci. Little is known about Vitruvius' life, but by his own descriptionDe Arch. Book 1, preface. section 2. he served as an artilleryman, the third class of arms in the Roman military offices. He probably served as a senior officer of artillery in charge of ''doctores ballistarum'' (artillery experts) and ''libratores'' who actually operated the machines. As an army engineer he specialized in the construction of '' ballista'' and '' scorpio'' artillery war machines for s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Floruit
''Floruit'' (; abbreviated fl. or occasionally flor.; from Latin for "they flourished") denotes a date or period during which a person was known to have been alive or active. In English, the unabbreviated word may also be used as a noun indicating the time when someone flourished. Etymology and use la, flōruit is the third-person singular perfect active indicative of the Latin verb ', ' "to bloom, flower, or flourish", from the noun ', ', "flower". Broadly, the term is employed in reference to the peak of activity for a person or movement. More specifically, it often is used in genealogy and historical writing when a person's birth or death dates are unknown, but some other evidence exists that indicates when they were alive. For example, if there are wills attested by John Jones in 1204, and 1229, and a record of his marriage in 1197, a record concerning him might be written as "John Jones (fl. 1197–1229)". The term is often used in art history when dating the care ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ctesibius
Ctesibius or Ktesibios or Tesibius ( grc-gre, Κτησίβιος; fl. 285–222 BC) was a Greek inventor and mathematician in Alexandria, Ptolemaic Egypt. He wrote the first treatises on the science of compressed air and its uses in pumps (and even in a kind of cannon). This, in combination with his work ''On pneumatics'' on the elasticity of air, earned him the title of "father of pneumatics." None of his written work has survived, including his ''Memorabilia,'' a compilation of his research that was cited by Athenaeus. Ctesibius' most commonly known invention today is a pipe organ (hydraulis), a predecessor of the modern church organ. Inventions Ctesibius was probably the first head of the Museum of Alexandria. Very little is known of his life, but his inventions were well known. It is said (possibly by Diogenes Laërtius) that his first career was as a barber. During his time as a barber, he invented a counterweight-adjustable mirror. Another invention of his included the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hellenistic
In Classical antiquity, the Hellenistic period covers the time in Mediterranean history after Classical Greece, between the death of Alexander the Great in 323 BC and the emergence of the Roman Empire, as signified by the Battle of Actium in 31 BC and the conquest of Ptolemaic Egypt the following year. The Ancient Greek word ''Hellas'' (, ''Hellás'') was gradually recognized as the name for Greece, from which the word ''Hellenistic'' was derived. "Hellenistic" is distinguished from "Hellenic" in that the latter refers to Greece itself, while the former encompasses all ancient territories under Greek influence, in particular the East after the conquests of Alexander the Great. After the Macedonian invasion of the Achaemenid Empire in 330 BC and its disintegration shortly after, the Hellenistic kingdoms were established throughout south-west Asia (Seleucid Empire, Kingdom of Pergamon), north-east Africa ( Ptolemaic Kingdom) and South Asia (Greco-Bactrian Kingdom, Indo ...
