Emerald (color)
Emerald is a color that is a shade of green. It is light and bright, with a faint bluish cast. The name comes from the color of emerald.
The first written use of "emerald" as a color name in English was in 1598.
Emerald are highly transparent color . This color is evenly distributed, with no eye-visible color zoning.

André-Marie Ampère
André-Marie Ampère (20 January 1775 – 10 June 1836) was a French physicist or a mathematician who helped discover electromagnetism. An electrical unit called the ampere is named after him.
Ampere was born in France in 1775. During his childhood, Ampere's father taught him Latin, until he found out that his son was talented in mathematical studies. However, young Ampere continued his study on Latin, so that he could understand and master the works of Euler and Bernoulli. In his later life, Ampere began to distinguish himself in mathematics, but also he studied history, travels, poetry, philosophy, and the natural sciences.
During the French Revolution, a great sorrow came to Ampere's life; he lost his father who was executed by revolutionaries. The death of his father brought a huge impact to Ampere.
In 1796, he met the daughter of a blacksmith living near Lyon named Julie Carron, and married her in 1799. Afterward, Ampere worked as a professor in Lyon, giving lessons in mathematics, chemistry, languages, and physics. He continued working as a professor even after the death of his wife in 1803. However, her death bothered Ampere for the rest of his life. Ampere died at Marseille and buried in the Cimetiere de Montmartre, Paris. In his work "Journal et correspondence", we can see his amiability and childlike simplicity of character.
Ampere is most known for establishing the relationship between electricity and magnetism, and combining them into a new field called electromagnetism, or electrodynamics. On September 11, 1820, Ampere heard from the discovery of H.C.Orsted that a magnetic needle can be activated by a voltaic current. Only a week later, he came up with a much more advanced version of that kindred phenomena. It was such an amazing development. On the same day, he also discovered like charges repel and different charges come towards each other.
Cyllene (moon)
Cyllene or ', is a moon of Jupiter. It was found by a team of astronomers from the University of Hawaii led by Scott S. Sheppard in 2003, getting the designation '.
Cyllene is about 2 kilometres in diameter, and orbits Jupiter at an average distance of 23,396,000 km in 731.099 days, at an inclination of 140° to the ecliptic (140° to Jupiter's equator), with an orbital eccentricity of 0.4116.
It was named in March 2005 after Cyllene, a naiad (stream nymph) or oread (mountain nymph) associated with Mount Kyllini, Greece. She was a daughter of Zeus (Jupiter).
It belongs to the Pasiphaë group, non-spherical retrograde moons orbiting Jupiter at distances ranging between 22,800,000 and 24,100,000 km, and with inclinations ranging between 144.5° and 158.3°.
Dive bomber
A dive bomber is a bomber aircraft that dives towards the ground so it can get very close to its targets so that it is more likely to hit them. This can also limit the chance of anti-aircraft fire hitting the plane.
Diving nearly vertically at the target, the aircraft will release the bombs very close to the target at high speed. This allows a dive bomber to drop bombs accurately on a relatively small target, or a moving target quite easily. Dive bombers were widely used to attack high value targets such as ships and bridges. This also had the advantage of attacking ships at a weak spot. A ship's armour was heaviest near the water. On the top of the ship, however, either the armour was very thin, or there was no armour at all. Also, dive bombing allowed relatively small aeroplanes carrying a limited bomb load to do more damage than usual.
Because of better bombsights and better anti-aircraft warfare after World War II, dive bombers were replaced by attack aircraft.

Fiberglass
Fiberglass (also called fibreglass and glass fibre) is material made from extremely fine fibers of glass.
It is used as a reinforcing material for many polymer products. The composite material, that is produced by this method is called "fiberglass" in popular usage. The proper names are fiber-reinforced polymer (FRP) or glass-reinforced plastic (GRP).
Glassmakers throughout history have experimented with glass fibers, but mass manufacture of fiberglass was only made possible when finer tools for machines were produced. The first major use was in "glass wool" for insulation, starting in the 1930s.
Glass fiber is formed when silica-based or other formulation glass is extruded into many fibers with small diameters that are suitable for textile processing. Glass is unlike other polymers because, even as a fiber, it has little crystalline structure (see amorphous solid). The properties of the structure of glass in its soft stage are very much like its properties when spun into fiber.
Bare fiberglass can cause skin irritation and cuts when handled without gloves. There have been concerns that fiberglass can be accidentally inhaled into the lungs, where it might cause cancer and other lung problems, similar to asbestos. Fiberglass has been called "man-made asbestos". Substitutes for fiberglass building insulation, such as cellulose and aerogel, have started to appear.
Composite material
Composite materials are made from two or more basic material mixed together. The materials can be natural or not, and keep their separate properties when mixed together. However, the composite material as a whole may behave differently from either of its parts. For example, reinforced concrete (made of concrete and steel) has resistance to pressure and to bending forces. Bullet-proof glass (made of glass and plastic) is more resistant to impact than either glass or plastic on their own.
Concrete itself is a composite material, one of the oldest man-made composites, used more than any other man-made material in the world.
Wood is a natural composite of cellulose fibres in a matrix of lignin. The earliest man-made composite materials were straw and mud combined to form bricks for building construction. This ancient brick-making process was documented by Egyptian tomb paintings.
Fibre-reinforced polymers are in wide use today, as is glass-reinforced plastic.
