Laos is one of the world's five remaining communist states. The only legal political party is the Lao People's Revolutionary Party (LPRP). The head of state is President Choummaly Sayasone. He is the General Secretary of the Lao People's Revolutionary Party.
Shortly after the end of the Vietnam War, the North Vietnamese Army (NVA) joined forces with the Pathet Lao, started a coup on December 2, 1975 to overthrow the royalist Lao government, and established a communist government that continues to run the country to this day.
The current head of government is Prime Minister Thongloun Sisoulith, as of 2016. The current President is Bounnhang Vorachith. Government policies are determined by the party. Important government decisions are checked by the Council of Ministers.

Amaterasu
Amaterasu (), Amaterasu-ōmikami ( or ) or Ōhirume-no-muchi-no-kami (), is a goddess in Japanese mythology. She is the Sun Goddess, and the most sacred of all Shinto deities. Her name, "Amaterasu", means ""(that which) illuminates Heaven."" Her shrine is at Ise.
Amaterasu is the sister of Susano'o, the god of the sea and storms, and of Tsukuyomi, the god of the moon. All three were created from Izanagi, when he washed his face to clean the dirtiness of Yomi, the underworld. Amaterasu was born when Izanagi washed out his left eye, Tsukuyomi was born from the washing of the right eye, and Susano'o from the washing of the nose.
The tales tell of great rivalry between Amaterasu and Susano'o. When he was to leave Heaven forever because Izanagi ordered him to, he went to say goodbye to his sister. Amaterasu, suspicious, proposed him a challenge: each of them was to turn an object of the other's into people. Amaterasu created three women from Susanoo's sword while he created five men from her necklace. Amaterasu said the men were hers because they were born of her necklace. Susano'o destroyed her rice fields, threw a dead pony into her loom, and killed one of her assistants in anger. For this, Amaterasu, sad, angry and scared, went to hide inside Ama-no-Iwato, the ""heavenly rock cave"", so the Sun was hidden and the world became dark for a long time. The Oni (devils of Japanese mythology) came out to the dark world, and the gods could not make Amaterasu come out of the cave.
The intelligent goddess of happiness, Ama-no-Uzume (天宇受売命), took a big bucket, turned it upside down near the cave entrance, and began a dance on it, tearing off her clothing in front of the other Kami. They thought this was so funny that they laughed happily.
Amaterasu heard them, and looked out to see why the gods were laughing. When she opened the cave, she saw her wonderful reflection in a mirror Uzume had put on a tree, and slowly came out of the cave.
At that moment, the god Ameno-Tajikarao (天手力男命) closed the cave behind her, so she could not go back in. Another god tied a magic rope across the entrance. The sun goddess was then asked by the Kami Ame-no-Koyane (天児屋根命) to go back with the gods. She agreed, and light came back to the earth, but Susanoo was punished by being banished from Heaven.
Organism
An organism is an individual living thing. It is easy to recognize a living thing, but not so easy to define it. Animals and plants are organisms, obviously. Organisms are a biotic, or living, part of the environment. Rocks and sunshine are parts of the non-living environment.
Organisms usually have five basic needs to continue their metabolism. They need air, water, nutrient (food), energy, and a place to live. However, not all living things need all these at the same time. Many organisms do not need access to air at all.
A little thought is needed about viruses. There is no agreement as to whether they should be regarded as living. They are made of protein and nucleic acid, and they evolve, which is a really important fact. However, they exist in two quite different phases. One phase is dormant, not active. The other is inside a living cell of some other organism. Then the virus is very active reproducing itself. Consider the parallel with a computer program. When in use it is active; when it is not, it is completely inactive. It is still a program all the same.
Another example from biology is the spore, which is a distribution phase of a bacteria, fungus or some plants. They are not active until they get to the right situation. They have all the working parts to build a complete organism, but for the moment it is switched off.
Some organisms are made up of millions of cells. They are multicellular organisms. Many can be seen without using a microscope.
Most organisms are so small that they cannot be seen with the naked eye. You need a microscope to see them. They are called microorganisms. Organisms can be made up of just one cell. They are called "unicellular organisms" or "single celled organisms". Examples include bacteria, and protozoa such as the "Amoeba" and "Paramecium".
The Tree of Life project works on the relationships between living things. Identifying a LUCA (last universal common ancestor) is one of its main aims. The LUCA is estimated to have lived some 3.8 billion years ago (sometime in the Palaeoarchaean era).
The idea came from Charles Darwin's "On the Origin of Species", "Therefore... probably all the organic beings which have ever lived on this earth have descended from some one primordial form..."
Kinetic energy
Kinetic energy is the energy that an object has because of its motion. This energy can be converted into other kinds, such as gravitational or electric potential energy, which is the energy that an object has because of its position in a gravitational or electric field.
Kinetic Energy is the maximum amount of work a moving body due to its motion can do, whereas Potential energy is the maximum amount of work a body can do due to its configuration or position in a field force. Kinetic Energy is valid for all sorts of forces as seen from this derivation.
but Potential Energy is not as can be seen here
which clearly suggests that only conservative forces can have potential energy associated with them.
The translational kinetic energy of an object is:

The rotational kinetic energy of an object is:

Potential energy
Potential energy is the stored or pent-up energy of an object. It is often contrasted with kinetic energy.
In physics, potential energy is the energy which an object has due to its position in a force field or which a system has due to the way its parts are arranged.
Common types include the gravitational potential energy of an object that depends on its vertical position and mass, the elastic potential energy of an extended spring, and the electric potential energy of a charge in an electric field. The SI unit for energy is the joule (symbol J).
Potential energy is often associated with restoring forces such as a spring or the force of gravity. The action of stretching the spring or lifting the mass is performed by an external force that works against the force field of the potential. This work is stored in the force field, which is said to be stored as potential energy. If the external force is removed the force field acts on the body to perform the work as it moves the body back to the initial position, reducing the stretch of the spring or causing a body to fall. When this happens, potential energy changes into kinetic energy. The total energy stays the same because of the law of conservation of energy.
Physicists say that potential energy is the difference between the energy of an object in a given position and its energy at a reference position.
