2010 American Television Series Endings
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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
2009 American Television Series Debuts
9 (nine) is the natural number following and preceding . Evolution of the Arabic digit In the beginning, various Indians wrote a digit 9 similar in shape to the modern closing question mark without the bottom dot. The Kshatrapa, Andhra and Gupta started curving the bottom vertical line coming up with a -look-alike. The Nagari continued the bottom stroke to make a circle and enclose the 3-look-alike, in much the same way that the sign @ encircles a lowercase ''a''. As time went on, the enclosing circle became bigger and its line continued beyond the circle downwards, as the 3-look-alike became smaller. Soon, all that was left of the 3-look-alike was a squiggle. The Arabs simply connected that squiggle to the downward stroke at the middle and subsequent European change was purely cosmetic. While the shape of the glyph for the digit 9 has an ascender in most modern typefaces, in typefaces with text figures the character usually has a descender, as, for example, in . The mod ...

Springald
A springald, or espringal, was a medieval torsion artillery device for throwing bolts. It is depicted in a diagram in an 11th-century Byzantine manuscript, but in Western Europe is more evident in the late 12th century and early 13th century. It was constructed on the same principles as an Ancient Greek or Roman ballista, but with inward swinging arms and threw bolts instead of stones. It was also known as a 'skein-bow', and was a torsion device using twisted skeins of silk or sinew to power two bow-arms. History The springald was a defensive bolt thrower based on the torsion mechanism of ancient ballistas, with two arms held in a skein of twisted sinew or hair. Unlike the ballista, it seems to have been housed in a rectangular box-like wooden structure and shot bolts instead of stones. According to digital models and projections, a springald could throw a bolt around 180 meters if mounted on a tower at an elevation of 15 degrees. It appears to have spread across Europe rapidly duri ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Leonardo's Self-propelled Cart
Leonardo's self-propelled cart is an invention designed by Leonardo da Vinci, considered the ancestor of the modern automobile. Info The machine is powered by two symmetric springs. While one spring would be enough to move the device, two symmetric springs probably looked like a more "logically perfect" solution. Leonardo had been well aware that the powering force provided by the springs drops significantly when they unwind. In order to deliver smooth and stable motion, the machine features a balance wheel, as used in clocks. The control mechanism is quite complex and allows it to follow a pre-programmed path automatically. The machine also features a mechanism similar to a differential that in addition allows the turning angle to be set. A replica of the self-propelled cart is kept at the museum Clos Lucé, near Château d'Amboise, in France. The television show ''Doing DaVinci'' also made a replica in 2009.

Tank
A tank is an armoured fighting vehicle intended as a primary offensive weapon in front-line ground combat. Tank designs are a balance of heavy firepower, strong armour, and good battlefield mobility provided by tracks and a powerful engine; usually their main armament is mounted in a turret. They are a mainstay of modern 20th and 21st century ground forces and a key part of combined arms combat. Modern tanks are versatile mobile land weapons platforms whose main armament is a large-caliber tank gun mounted in a rotating gun turret, supplemented by machine guns or other ranged weapons such as anti-tank guided missiles or rocket launchers. They have heavy vehicle armour which provides protection for the crew, the vehicle's munition storage, fuel tank and propulsion systems. The use of tracks rather than wheels provides improved operational mobility which allows the tank to overcome rugged terrain and adverse conditions such as mud and ice/snow better than wheeled vehicles, ...

Leonardo Da Vinci's Tank

The covering was to be made of wood and reinforced with metal plates that add to the thickness. Slanting angles would deflect enemy fire. The machine was powered by two large cranks operated internally by four strong men. The vehicle was equipped with an array of light cannons, placed around the perimeter.The gears of the design were located in a reversed order, making ...
