In atoms, electrons can be said to go around the nucleus of an atom and possess some spinning energy. They also have their own spin, like a spinning top, which is separate from the atom and they keep even when they are moving freely. There are two ways for something to spin, clockwise and anti-clockwise. In the tiny quantum world the terms 'up' or 'down' are used instead.
The electron spin of large numbers of electrons plays a role as a source of the magnetism in permanent magnets. In most materials these spins are random in direction and so no magnetic field results. In normal electronics the flow of current in a wire can also be used to produce a magnetic field which is known as electromagnetism. Neither of these form a part of spintonics.
In spintronics the property of the spin of the electrons themselves is used directly. It makes use of the electrons in a solid metal or semiconductor.
In spintronics the electron spin of just a few electrons in a material are made to align in one direction by briefly applying a very large magnetic field. Even when the magnetic field is removed the electrons will remain aligned in their spins. This alignment will slowly fade away over time but will persist for a while.
Since these aligned spins produce a resultant magnet field they can be detected and even used to move the electrons.
The deliberate moving of only those electrons with a certain spin can be used to store information and this technology has been called spintronics to distinguish it from conventional use of electrons in electronics which uses their electric charge only.
Spintonics is an area of research in which scientists are trying to make useful devices and are making progress. Some devices write the electron spin codes into the surface of a moving disk and others make them in sold transistor junctions as RAM. They promise a technology that could create faster and smaller electronic devices that use less energy.
Nawab of Awadh
The Nawab of Awadh or the Nawab of Oudh () was the title of the rulers who governed the state of Oudh or Awadh in India during the 18th and 19th centuries. The Nawabs of Awadh belonged to a dynasty of Qara-Qoyunlu origin from Nishapur. Saadat Khan (1722–1739) became the first Nawab of Awadh in 1722. He was a Mughal wazir and the founder of the state of Awadh.
Antioch College
Antioch College is a private, liberal arts college in Yellow Springs, Ohio, in the United States. Established in 1850 by the Christian Connection, the college began operating in 1852; politician and education expert Horace Mann became its first president. It was the founding, forming college of Antioch University, which Antioch College outlived until 2008. The College remained out of business for three years before being reestablished in 2011, and fully disconnected from the university as an independent institution by 2014.
The College has produced two Nobel Prize winners. José Ramos-Horta, the 1996 laureate for Peace, earned his Master of Arts in 1984. Mario Capecchi, the 2007 laureate for Nobel Prize for Physiology or Medicine, earned his Bachelor of Science in 1961.
Keytar
A keytar is a musical instrument. It is shaped and held like a guitar, but has keys like a keyboard. Keytars are lightweight keyboards that have a strap that is put around the neck and shoulders. The instrument has a keyboard for playing musical notes and sounds. The earliest keytars were created around the 1970's. This picture of a keytar is one of the most popular keytars. Most popular keytars are seen with a red guitar neck and played in 1980 movies. first appeared in a magazine in 1980.

Show, don't tell
Show, don't tell is a type of writing technique used by authors. Instead of explaining a story, as in a summary, a writer makes the reader feel what is happening. It creates a picture of something in the reader's mind. When the reader gets a clear mental picture the story becomes more interesting. The technique is used in both fiction and non-fiction writing.
In the first example, the author is telling what the character feels. In the second example, the author is allowing the reader to picture what the character was experiencing when she opened the door.
Good writing may involve both showing and telling. A scene shows the reader what is happening. It allows the reader to experience the action and emotions of the people in the story. A summary is often used between scenes to connect them together to create a story. Another use of summaries is in places where a part of the story needs to be brief. Showing takes more words than telling. Less important parts of a story are sometimes mentioned very briefly.
