Wave

In physics, a wave is an oscillation accompanied by a transfer of energy that travels through space or mass. Frequency refers to the addition of time. Wave motion transfers energy from one point to another, which displace particles of the transmission medium—that is, with little or no associated mass transport. Waves consist, instead, of oscillations or vibrations (of a physical quantity), around almost fixed locations.

There are two main types of waves. Mechanical waves propagate through a medium, and the substance of this medium is deformed. The deformation reverses itself owing to restoring forces resulting from its deformation. For example, sound waves propagate via air molecules colliding with their neighbors. When air molecules collide, they also bounce away from each other (a restoring force). This keeps the molecules from continuing to travel in the direction of the wave.

The second main type of wave, electromagnetic waves, do not require a medium. Instead, they consist of periodic oscillations of electrical and magnetic fields originally generated by charged particles, and can therefore travel through a vacuum. These types of waves vary in wavelength, and include radio waves, microwaves, infrared radiation, visible light, ultraviolet radiation, X-rays, and gamma rays.

Every Breaking Wave

"Every Breaking Wave" is a song by Irish rock band U2. It is the second track from their thirteenth studio album, Songs of Innocence, and was released as its second single. It was produced by Danger Mouse and Ryan Tedder, with additional production from Declan Gaffney.

Writing and recording

"Every Breaking Wave" was originally intended to be included on U2's 2009 studio album No Line on the Horizon. In an article previewing the album several weeks before release, Rolling Stone called the song a "swelling soul-pop song, with bright synth sounds influenced by OMD". However, the track was ultimately left off the album, much to the chagrin of some in the U2 camp; speaking of material the band were working on, lead singer Bono said the song was producer Jimmy Iovine's favorite. Bono mentioned tentative plans for the group to release a follow-up record, Songs of Ascent, comprising songs from No Line's recording sessions, and said that the first single was intended to be "Every Breaking Wave". However, the project was continually delayed, as U2 struggled to complete an album to their satisfaction and were limited by other commitments.

War Commander

War Commander is an online multiplayer game developed by Kixeye. The game has 100,000 active users everyday. Made in 2010, the game is still in open beta.

Gameplay

The game is a post-apocalyptic landscape 30 years after civilization collapsed. The player fights other fractions for oil, metal and thorium. There are tanks, aircraft and infantry that the player can fight with. Every month there is an event where the player must defend against waves of enemy to gain points from winning the attack wave. After you defend you get points to spend in the event shop for new units.

Sectors

Sectors are sections of the world where the player base and others are at. There are 420 sectors where the player can relocate to. There are about 500 people in a sector.

Infamy

Infamy is a measure of a player's skill in combat against other players. Infamy is shown on top of a players base in the map. It is shown on a leaderboard where players can be compared. To get infamy, a player must attack another player's base and for each star they earn while destroying that base and they get the most infamy if you get 3 stars.

United Nations

The United Nations (UN) is an intergovernmental organization to promote international co-operation. A replacement for the ineffective League of Nations, the organization was established on 24 October 1945 after World War II in order to prevent another such conflict. At its founding, the UN had 51 member states; there are now 193. The headquarters of the United Nations is in Manhattan, New York City, and experiences extraterritoriality. Further main offices are situated in Geneva, Nairobi and Vienna. The organization is financed by assessed and voluntary contributions from its member states. Its objectives include maintaining international peace and security, promoting human rights, fostering social and economic development, protecting the environment, and providing humanitarian aid in cases of famine, natural disaster, and armed conflict.

During the Second World War, US President Franklin D. Roosevelt initiated talks on a successor agency to the League of Nations, and the United Nations Charter was drafted at a conference in April–June 1945; this charter took effect 24 October 1945, and the UN began operation. The UN's mission to preserve world peace was complicated in its early decades by the Cold War between the US and Soviet Union and their respective allies. The organization participated in major actions in Korea and the Congo, as well as approving the creation of the state of Israel in 1947. The organization's membership grew significantly following widespread decolonization in the 1960s, and by the 1970s its budget for economic and social development programmes far outstripped its spending on peacekeeping. After the end of the Cold War, the UN took on major military and peacekeeping missions across the world with varying degrees of success.
