Google Cloud PlatformGoogle Cloud Platform (GCP), offered by Google, is a suite of cloud computing services that runs on the same infrastructure that Google uses internally for its end-user products, such as Google Search, Gmail, Google Drive, and YouTube. Alongside a set of management tools, it provides a series of modular cloud services including computing, data storage, data analytics and machine learning. Registration requires a credit card or bank account details.
Wind turbine designWind turbine design is the process of defining the form and configuration of a wind turbine to extract energy from the wind. An installation consists of the systems needed to capture the wind's energy, point the turbine into the wind, convert mechanical rotation into electrical power, and other systems to start, stop, and control the turbine. In 1919, German physicist Albert Betz showed that for a hypothetical ideal wind-energy extraction machine, the fundamental laws of conservation of mass and energy allowed no more than 16/27 (59.
Peace movementA peace movement is a social movement which seeks to achieve ideals such as the ending of a particular war (or wars) or minimizing inter-human violence in a particular place or situation. They are often linked to the goal of achieving world peace. Some of the methods used to achieve these goals include advocacy of pacifism, nonviolent resistance, diplomacy, boycotts, peace camps, ethical consumerism, supporting anti-war political candidates, supporting legislation to remove profits from government contracts to the military–industrial complex, banning guns, creating tools for open government and transparency, direct democracy, supporting whistleblowers who expose war crimes or conspiracies to create wars, demonstrations, and political lobbying.
Propellant mass fractionIn aerospace engineering, the propellant mass fraction is the portion of a vehicle's mass which does not reach the destination, usually used as a measure of the vehicle's performance. In other words, the propellant mass fraction is the ratio between the propellant mass and the initial mass of the vehicle. In a spacecraft, the destination is usually an orbit, while for aircraft it is their landing location. A higher mass fraction represents less weight in a design.
Peace symbolsA number of peace symbols have been used many ways in various cultures and contexts. The dove and olive branch was used symbolically by early Christians and then eventually became a secular peace symbol, popularized by a Dove lithograph by Pablo Picasso after World War II. In the 1950s the "peace sign", as it is known today (also known as "peace and love"), was designed by Gerald Holtom as the logo for the British Campaign for Nuclear Disarmament (CND), a group at the forefront of the peace movement in the UK, and adopted by anti-war and counterculture activists in the US and elsewhere.
Mass ratioIn aerospace engineering, mass ratio is a measure of the efficiency of a rocket. It describes how much more massive the vehicle is with propellant than without; that is, the ratio of the rocket's wet mass (vehicle plus contents plus propellant) to its dry mass (vehicle plus contents). A more efficient rocket design requires less propellant to achieve a given goal, and would therefore have a lower mass ratio; however, for any given efficiency a higher mass ratio typically permits the vehicle to achieve higher delta-v.
World peaceWorld peace is the concept of an ideal state of peace within and among all people and nations on Planet Earth. Different cultures, religions, philosophies, and organizations have varying concepts on how such a state would come about. Various religious and secular organizations have the stated aim of achieving world peace through addressing human rights, technology, education, engineering, medicine, or diplomacy used as an end to all forms of fighting.
