The Amazing Thing

Gold

Gold is the most malleable of all metals; a single gram can be beaten into a sheet of 1 square meter, or an ounce into 300 square feet. Gold leaf can be beaten thin enough to become transparent. The transmitted light appears greenish blue, because gold strongly reflects yellow and red. Such semi-transparent sheets also strongly reflect infrared light, making them useful as infrared (radiant heat) shields in visors of heat-resistant suits, and in sun-visors f
or spacesuits.

Whereas most other pure metals are gray or silvery white, gold is yellow. This color is determined by the density of loosely bound (valence) electrons; those electrons oscillate as a collective "plasma" medium described in terms of a quasiparticle called plasmon. The frequency of these oscillations lies in the ultraviolet range for most metals, but it falls into the visible range for gold due to subtle relativistic effects that affect the orbitals around gold atoms. Similar effects impart a golden hue to metallic caesium.

Application in the life:

Monetery Exchange

Gold has been widely used throughout the world as money, for efficient indirect exchange (versus barter), and to store wealth in hoards. For exchange purposes, mints produce standardized gol bullion coins, bars and other units of fixed weight and purity


Investment:

Many holders of gold store it in form of bullion coins or bars as a hedge against inflation or other economic disruptions. However, economist Martin Feldstein does not believe gold serves as a hedge against inflation or currency depreciation

Jewelry
Because of the softness of pure (24k) gold, it is usually alloyed with base metals for use in jewelry, altering its hardness and ductility, melting point, color and other ^[
properties. Alloys with lower carat rating, typically 22k, 18k, 14k or 10k, contain higher percentages of copper or other base metals or silver or palladium in the alloy. Copper is the most commonly used base metal, yielding a redder color.

I'm can't wait for Dewa Athena, do you know Dewa Athena? 
Dewa Athena is Sports Inter-Class Tournament, many sports competition in this event. there are soccer, basketball, and many more. In saturday, 15th february we had a Opening Ceremony of Dewa Athena. We must gathered at 7.am but the Opening Ceremony started about 8.15am it's very late.

 Dewa Athena would be finished in April. My class that day had 2 match, soccer and estafet. We played about 10.00 pm and 12.00 pm. Our match became the opening of the 1st day of Dewa Athena.

Back to Opening Ceremony, first our Headmaster greet us. He said to us to play with Sportif and don't be cheating. And the ceremony envieled with the lightning torch. it was incredible.
