Weighing Scale
A scale or balance is a device used to measure weight or mass. These are also known as mass scales, weight scales, mass balances, massometers, and weight balances. The traditional scale consists of two plates or bowls suspended at equal distances from a fulcrum. One plate holds an object of unknown mass (or weight), while objects of known mass or weight, called '' weights'', are added to the other plate until mechanical equilibrium is achieved and the plates level off, which happens when the masses on the two plates are equal. The perfect scale rests at neutral. A spring scale will make use of a spring of known stiffness to determine mass (or weight). Suspending a certain mass will extend the spring by a certain amount depending on the spring's stiffness (or spring constant). The heavier the object, the more the spring stretches, as described in Hooke's law. Other types of scales making use of different physical principles also exist. Some scales can be calibrate ...

Kilogram
The kilogram (also spelled kilogramme) is the base unit of mass in the International System of Units (SI), equal to one thousand grams. It has the unit symbol kg. The word "kilogram" is formed from the combination of the metric prefix kilo- (meaning one thousand) and gram; it is colloquially shortened to "kilo" (plural "kilos"). The kilogram is an SI base unit, defined ultimately in terms of three defining constants of the SI, namely a specific transition frequency of the caesium-133 atom, the speed of light, and the Planck constant. A properly equipped metrology laboratory can calibrate a mass measurement instrument such as a Kibble balance as a primary standard for the kilogram mass. The kilogram was originally defined in 1795 during the French Revolution as the mass of one litre of water (originally at 0 °C, later changed to the temperature of its maximum density, approximately 4 °C). The current definition of a kilogram agrees with this original defini ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Steelyard Balance
A steelyard balance, steelyard, or stilyard is a straight-beam Weighing scale, balance with arms of unequal length. It incorporates a counterweight which slides along the longer arm to counterbalance the load and indicate its weight. A steelyard is also known as a Roman steelyard or Roman balance. Structure The steelyard comprises a balance beam which is suspended from a lever/pivot or fulcrum which is very close to one end of the beam. The two parts of the beam which flank the pivot are the arms. The arm from which the object to be weighed (the load) is hung is short and is located close to the pivot point. The other arm is longer, is graduated and incorporates a counterweight which can be moved along the arm until the two arms are balanced about the pivot, at which time the weight of the load is indicated by the position of the counterweight. Mechanism The steelyard exemplifies the lever, law of the lever, wherein, when balanced, the weight of the object being weighed, mul ...

Assyrian Lion Weights
The Assyrian lion weights are a group of bronze statues of lions, discovered in archaeological excavations in or adjacent to ancient Assyria. The first published, and the most notable, are a group of sixteen bronze Mesopotamian weights found at Nimrud in the late 1840s and now in the British Museum. They are considered to date from the 8th century BCE, with bilingual inscriptions in both cuneiform and Phoenician characters; the latter inscriptions are known as CIS II 1-14. Nimrud weights The Nimrud weights date from the 8th century BCE and have bilingual inscriptions in both cuneiform and Phoenician characters. The Phoenician inscriptions are epigraphically from the same period as the Mesha Stele. They are one of the most important groups of artifacts evidencing the "Aramaic" form of the Phoenician script. At the time of their discovery, they were the oldest Phoenician-style inscription that had been discovered. The weights were discovered by Austen Henry Layard in his ear ...

Minoan Civilization
The Minoan civilization was a Bronze Age culture which was centered on the island of Crete. Known for its monumental architecture and energetic art, it is often regarded as the first civilization in Europe. The ruins of the Minoan palaces at Knossos and Phaistos are popular tourist attractions. The Minoan civilization developed from the local Neolithic culture around 3100BC, with complex urban settlements beginning around 2000BC. After 1450BC, they came under the cultural and perhaps political domination of the mainland Mycenaean Greeks, forming a hybrid culture which lasted until around 1100BC. Minoan art included elaborately decorated pottery, seals, figurines, and colorful frescoes. Typical subjects include nature and ritual. Minoan art is often described as having a fantastical or ecstatic quality, with figures rendered in a manner suggesting motion. Little is known about the structure of Minoan society. Minoan art contains no unambiguous depiction of a monarch, and t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Warring States Period
The Warring States period in history of China, Chinese history (221 BC) comprises the final two and a half centuries of the Zhou dynasty (256 BC), which were characterized by frequent warfare, bureaucratic and military reforms, and struggles for greater hegemonic influence among the ancient Chinese states, various autonomous feudal states of the Eastern Zhou dynasty.

While scholars have identified several different dates as marking the beginning of the Warring States period, Sima Qian's choice of 475 BC, the first year of King Yuan of Zhou's reign, is the most often cited due to the paucity of preceding annals after th ...

Indus Valley Civilisation
The Indus Valley Civilisation (IVC), also known as the Indus Civilisation, was a Bronze Age civilisation in the Northwestern South Asia, northwestern regions of South Asia, lasting from 3300 Common Era, BCE to 1300 BCE, and in its mature form from 2600 BCE to 1900 BCE. Together with ancient Egypt and Mesopotamia, it was one of three early civilisations of the Near East and South Asia, and of the three, the most widespread, its sites spanning an area including much of Pakistan, Northwest India, northwestern India and northeast Afghanistan. The civilisation flourished both in the alluvial plain of the Indus River, which flows through the length of Pakistan, and along a system of perennial monsoon-fed rivers that once coursed in the vicinity of the Ghaggar-Hakra River, Ghaggar-Hakra, a seasonal river in northwest India and eastern Pakistan. The term ''Harappan'' is sometimes applied to the Indus Civilisation after its type site Harappa, the first to be exc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sneferu
Sneferu or Soris (c. 2600 BC) was an ancient Egyptian monarch and the first pharaoh of the Fourth Dynasty of Egypt, during the earlier half of the Old Kingdom period (26th century BC). He introduced major innovations in the design and construction of pyramids, and at least three of his pyramids survive to this day. Estimates of his reign vary, with for instance ''The Oxford History of Ancient Egypt'' suggesting a reign from around 2613 to 2589 BC, a reign of 24 years, while Rolf Krauss suggests a 30-year reign, and Rainer Stadelmann a 48-year reign. Sneferu's name His name means "He has perfected me", from ''Ḥr-nb-mꜣꜥt-snfr-wj'' "Horus, Lord of Maat, has perfected me", and is sometimes read Snefru or Snofru. He is also known under his Hellenized name Soris ( by Manetho). Reign length The 24-year Turin Canon figure for Sneferu's reign is considered today to be an underestimate since this king's highest-known date is an inscription discovered at the Red Pyramid of Dahshu ...
