Angkor Wat Land of Gods (Part 01/02)

Angkor Wat

Angkor Wat (Khmer: អង្គរវត្ត or "Capital Temple") is a temple complex in Cambodia and the largest religious monument in the world, with site measuring 162.6 hectares (1,626,000 sq meters). It was originally constructed as a Hindu temple for the Khmer Empire, gradually transforming into a Buddhist temple toward the end of the 12th century. It was built by the Khmer King Suryavarman II in the early 12th century in Yaśodharapura (Khmer: យសោធរបុរៈ, present-day Angkor), the capital of the Khmer Empire, as his state temple and eventual mausoleum.

Breaking from the Shaiva tradition of previous kings, Angkor Wat was instead dedicated to Vishnu. As the best-preserved temple at the site, it is the only one to have remained a significant religious center since its foundation. The temple is at the top of the high classical style of Khmer architecture. It has become a symbol of Cambodia, appearing on its national flag, and it is the country's prime attraction for visitors.

Angkor Wat combines two basic plans of Khmer temple architecture: the temple-mountain and the later galleried temple. It is designed to represent Mount Meru, home of the devas in Hindu mythology: within a moat and an outer wall 3.6 kilometres (2.2 mi) long are three rectangular galleries, each raised above the next.

At the centre of the temple stands a quincunx of towers. Unlike most Angkorian temples, Angkor Wat is oriented to the west; scholars are divided as to the significance of this. The temple is admired for the grandeur and harmony of the architecture, its extensive bas-reliefs, and for the numerous devatas adorning its walls.

The modern name, Angkor Wat, means "Temple City" or "City of Temples" in Khmer; Angkor, meaning "city" or "capital city", is a vernacular form of the word nokor (នគរ), which comes from the Sanskrit word nagara (Devanāgarī: नगर). Wat is the Khmer word for "temple grounds", also dervied from Sanskrit vāṭa (Devanāgarī: वाट), meaning "enclosure".

Robam Tep Apsara

History

In 1940s, Queen Sisowath Kossomak Nearirath Serey Vatthana, the wife of King Norodom Suramarit, was sent an invitation to vist the Sothearath primary school. While there she saw the school mistress prepare an inspirational angkor apsara dance performed by young school children in the paper apsara costume including Crown, Sampot and Flower, all referencing Apsara represented at Angkor Wat.

The Queen got the idea to re-create the dance, which led her first granddaughter, Princess Norodom Buppha Devi, a daughter of Norodom Sihanouk, to become the first professional apsara dancer of the modern era. The Princess started practicing the dance at 5 years old and danced apsara for first time during King Norodom Sihanouk's tenure.

In 1967, the fine–boned young princess, clad in silk and glittering jewels, performed beneath the stars on the open pavilion within the palace walls, accompanied by the royal dance troupe and the pinpeat orchestra. Selected by her grandmother, Queen Sisowath Kossomak, to become a dancer when she was only a baby. She toured the world as the principal dancer of the apsara role.

Polar Bears A Summer Odyssey (2012)

Polar Bears A Summer Odyssey

Imagine sticking your nose in the air and sniffing the smell of a hamburger cooking a mile away. Some bears can do just that. Bears have a keen sense of smell. They use this sense to help them find food. Bears are meat eaters, or carnivores. But most bears also eat fruits, nuts, and other foods. Bears live in North America, South America, Europe, and Asia. They do not live in Africa, Australia, or Antarctica.

WHAT MAKES A BEAR A BEAR?

Bears are powerful animals with lots of thick fur and a short, stumpy tail. They have big heads with a long snout (nose and mouth) and small ears and eyes. They have four short legs that end in paws, each with five sharp claws. They use their claws to climb trees, dig up roots, or catch prey. Male bears are much bigger than female bears.

BEARS ARE LONERS

Bears usually live alone unless they are mothers with cubs. Each bear claims an area, or territory, as its own. It chases other bears away. A bear stands up on its hind legs to look frightening. It uses its claws to slash at enemies.

Bears roam over large areas looking for food. They need to eat a lot of food for energy. Most bears can climb trees to find honey in a bee’s nest or other food. Polar bears and brown bears are too heavy to climb trees. These bears are the biggest of all the bears. They can weigh up to 1,760 pounds (800 kilograms).

WINTER SLEEP

Bears that live in cold places go into dens and sleep through most of the winter. They make their dens in caves, trees trunks, and other hollow places. They eat plenty of food during the summer to store up body fat. Their body fat gives them energy to sleep through the cold winter.

BEAR CUBS

Bears mate in the spring after they wake up from winter sleep. The cubs are born the next winter in the mother’s den. Females usually have between one and three cubs at a time. The newborn cubs are tiny, blind, and helpless. They have no teeth or hair. But they are warm and safe in the mother bear’s den. They feed on their mother’s milk. The milk is rich and helps the baby bears grow quickly. When they are three months old, the cubs are ready to go outside the den and look for food. The cubs stay close by their mother, however.

Cubs live with their mother until they are two or three years old. During this time, they learn what to eat and where to find food. Then they go off and find their own territory. When females are between four and seven years old, they are ready to have cubs of their own. Bears in the wild may live to be from 25 to 40 years old, but scientists do not know for sure.

KINDS OF BEARS

There are eight major kinds, or species, of bears. These species are giant panda, spectacled bear, sun bear, sloth bear, Asiatic black bear, American black bear, brown bear, and polar bear. The best-known bears are giant pandas, American black bears, brown bears, and polar bears.

GIANT PANDA

The giant panda has shaggy white fur with a black patch around each eye and a ring of black around the shoulders, front legs, and chest. The biggest giant pandas are about 5 feet (1.5 meters) long and weigh up to 220 pounds (100 kilograms).

The giant panda lives in the mountains of south central China. It eats the leaves and stems of bamboo trees. The giant panda is an endangered species. There may only be about 1,000 of these animals left in the wild.

AMERICAN BLACK BEAR

Most American black bears have black fur. But some have reddish or yellowish fur. Males can be 6 feet (1.8 meters) long and weigh up to 660 pounds (300 kilograms).

American black bears live in Canada, the United States, and northern Mexico. Scientists think there may be as many as 700,000 black bears in the United States. American black bears eat grasses, berries, acorns, and walnuts.

BROWN BEAR

Brown bears have fur that is light or dark brown. They also have a big hump on their shoulders. Their snout is turned upward. Brown bears live in Asia, Europe, and North America. Grizzly bears are a kind of brown bear.

Brown bears are among the largest bears. Large males weigh up to 1,760 pounds (800 kilograms). The Alaskan brown bear and other brown bears that live along seacoasts eat salmon. Brown bears that live inland eat plants and insects. There are more than 120,000 brown bears in Russia and about 32,000 in Alaska.

POLAR BEAR

Polar bears have white fur. They live in the Arctic near the North Pole. Their fur blends in with the ice and snow all around them. Polar bears are huge. Big males can be 7 feet (2 meters) long and weigh as much as a big brown bear.

Polar bears eat mostly meat. Their favorite foods are seal and walrus. Polar bears can hunt for food on land or in the icy water. Polar bears are very good swimmers. Their thick fur keeps them warm and dry.

BEARS AND PEOPLE

People have hunted bears since prehistoric times. They ate bear meat and used bear fur as robes or blankets to keep warm. Once there were many bears all over the world. Today, there are few. People destroyed the places where bears lived when they cleared land for farms and towns. Governments and conservation groups are working to save the bears that are left.

The Lady (2011 film)

History of the movie

The Lady is a French-British biographical film directed by Luc Besson, starring Michelle Yeoh as Aung San Suu Kyi and David Thewlis[8] as her late husband Michael Aris.Yeoh called the film "a labour of love" but also confessed it had felt intimidating for her to play the Nobel laureate.

In 1947, when Aung San Suu Kyi is two years old, her father Aung San leads Burma to independence. But soon afterwards, on 19 July 1947, he along with a group of his colleagues is assassinated by a group of armed men in uniform. As an adult Suu Kyi goes to England, finds a loving husband, and has a happy family life. But in 1988 her mother's poor health forces her to return to Burma where her father, Aung San, is still widely remembered.

When she visits her mother in the hospital in 1988, she meets many of the people who are wounded during the Tatmadaw's crackdown in the 8888 Uprising. She realises that political change is needed in Burma and is soon drawn into the movement to promote reform. She accepts the role of icon in support of self-determination by the Burmese people and devotes herself to activities in support of goals of greater political freedoms. Suu Kyi founds a political party and clearly wins the 1990 elections.

However, the Burmese military refuse to accept the result of the election and move to bring Suu Kyi under control. She and her family become separated when her husband and children are banned from Burma and she is put under a house arrest for more than a decade. Yet their relentless struggling for Suu Kyi's recognition outside Burma is her guarantee she won't be forgotten and cannot disappear unnoticed.

Due to her family's efforts, she becomes the first woman in Asia to be awarded the Nobel Peace Prize. Yet their separation continues because Suu Kyi can neither attend the ceremony nor can her husband Michael Aris see her one last time before his early death.
