Do you know Achilles?

Achilles, in Greek mythology, greatest of the Greek warriors in the Trojan War. He was the son of the sea nymph Thetis and Peleus, king of the Myrmidons of Thessaly. When the Fates prophesied that Achilles would die in the Trojan War, Thetis attempted to make her infant son immortal. In one version of the story, Thetis rubbed Achilles with ambrosia and placed him in the hearth fire to make him immortal. According to a later legend, she bathed him in the River Styx. The waters made him invulnerable except for the heel by which his mother held him. The term Achilles heel has become popularized to refer to someone’s or something’s key weakness.

While Achilles was growing up, the Greek armies were preparing for their assault on Troy in Asia Minor. Knowing that her son was fated to die if he took part in the war, Achilles’s mother dressed him in women’s clothing and sent him to Skyros to live among the young women in the court of King Lycomedes. Warned that they could not conquer Troy without the aid of Achilles, the Greeks sent Odysseus, king of Ithaca, to find him. Disguised as a peddler, Odysseus went to Skyros bearing a shield and a spear among his goods. When Achilles betrayed his identity by seizing the weapons, Odysseus persuaded him to join the Greek expedition to Troy.

Achilles fought many battles during the Greeks’ ten-year siege of Troy. When the Mycenaean king Agamemnon seized the captive slave Briseis from him during the war, Achilles withdrew the Myrmidons from battle and sulked in his tent. The Trojans, emboldened by his absence, attacked the Greeks and drove them into headlong retreat. Then Patroclus, Achilles’s friend and companion, begged Achilles to lend him his armor and let him lead the Myrmidons into battle. Achilles consented.

Patroclus was killed by the Trojan prince Hector. Afterward the grief-stricken Achilles returned to battle, slew Hector, and dragged his body in triumph behind his chariot. Achilles fought his last battle with Memnon, king of the Ethiopians. After killing the king, Achilles led the Greeks to the walls of Troy. There he was mortally wounded in the heel by Paris, the Trojan prince whose abduction of Helen, queen of Sparta, started the Trojan War. The quarrel between Achilles and Agamemnon, the subsequent battle, and the ransoming of Hector’s body are recounted in the Iliad, an ancient Greek epic poem attributed to the poet Homer.

Why Hair Goes Gray?

Why Hair Goes Gray
Study Blames a Chain Reaction That Makes Hair Bleach Itself From the Inside Out

Feb. 25, 2009 -- Scientists may have figured out why hair turns gray, and their finding may open the door to new anti-graying strategies.

New research shows that hair turns gray as a result of a chemical chain reaction that causes hair to bleach itself from the inside out.

The process starts when there is a dip in levels of an enzyme called catalase. That catalase shortfall means that the hydrogen peroxide that naturally occurs in hair can't be broken down. So hydrogen peroxide builds up in the hair, and because other enzymes that would repair hydrogen peroxide's damage are also in short supply, the hair goes gray.

Putting the brakes on that chemical chain reaction "could have great implications in the hair graying scenario in humans," write the researchers, who included Karin Schallreuter, a professor clinical and experimental dermatology at England's University of Bradford.

Mid Term's 1st Week in CorelDRAW

In our 1st class in Digital Design subject on Mid Term is about on knowing how could you draw a drawing or a picture in CorelDRAW much faster and easier by using those commands.
This are the commands:

In the 1st row at the upermost part of the CorelDRAW window or the "Menu Bar"
1st click the "Arrange" menu,
Then 2nd click or choose "Shaping"
3rd after you click on "Shaping" there a few options or commands that will apear that you could choose the ( Weld, Trim, Intersect, Simplify, Front Minus Back and Back Minus Front) those are the options or commands that you could choose from.

These are the uses of those commands:

Weld - This command is used to combines two or more shapes.

Trim - This command is used for trimming two or more shapes, the shape that is in the front of another shape will be the one who will trim on the shape under the other shape. The overlapped part of two shapes will be the part that will be trimmed.

Intersect - This command will make the intersection or the overlapped part of the two shapes become an another part/shape or simply be separated to the two main shapes.

Simplify - It is almost the same as the "Trim" command.

Front minus Back - The intersected part of the back shape and the shape itself will be cut through the front shape. And the shape at the back itself will be deleted.

Back minus Front - The intersected part of the front shape and the shape itself will be cut through the back shape. And the shape at the front itself will be deleted also.
