A One-time pad is a method of encryption. It is a "symmetrical cipher", which means the same key is needed for encryption and decryption. A one time pad uses a key that is either as long or longer than the message it encrypts. The key must only be used once, and after it is used, a new key must be generated and shared for the cipher to remain secure.
If this method is used correctly, it is impossible to decrypt or break the encryption without the key. Failure to make and share random keys has led to successful cryptanalysis, as in the Venona project.
Because of these requirements, it is rarely used today.
One-time pads were created all the way in 1882 by Frank Miller. After the invention in 1917, Gilbert Vernam invented and patented an electronic version based on teleprinter technologies.

Sayyid
Syed or Sayyid or Sayed is a title of honour and respect in Islam. It is originally a word from the Arabic language which means 'Sir' or 'Mister' or 'Honourable Person'.
However, the word is now also used in different parts of the world by Muslims to refer specially to a descendant of the Prophet Muhammad. For example, if someone is called a 'Syed/Sayyid' in India, Pakistan, Bangladesh, Iran, Afghanistan, Indonesia, Malaysia etc., then that person is descended from the prophet of Islam.
In Afghanistan, Sadat (Sayyids) are recognized as an ethnic group. On 13 March 2019, addressing the Sadat gathering at the presidential palace (Arg), President Ashraf Ghani said that he will issue a decree on the inclusion of Sadat ethnic group in new electronic national identity card (e-NIC).

Planetarium
A planetarium is a theater built to show educational and entertaining presentations about astronomy and the night sky. They are also used for training in celestial navigation. A main part of most planetariums is the large dome-shaped screen onto which images of stars, planets and other celestial objects can be shown and made to move to show the 'motions of the heavens'. The celestial scenes can be created using many different technologies. These include 'star balls' that combine optical and electro-mechanical technology, slide projector, video, full dome projector systems, and lasers. These technologies are used together to give an accurate image of the motion of the sky. Common systems can be set to show the sky at any point in time, past or present. They often show the night sky as it would appear from any point of latitude on Earth.
There are many different sizes of planetariums. They can be as large as the Hayden Planetarium's 21-meter dome. It seats 423 people. They can also be as small as a three-meter portable domes where children sit on the floor. These portable planetariums are used for education presentations outside of the permanent planetariums at museums and science centers.
The term "planetarium" is sometimes used to mean other things which show the solar system. These include computer simulations or an orrery. Planetarium software refers to software that creates a three dimensional image of the sky on a two dimensional computer screen. The term "planetarian" is used for someone who works at a planetarium. The plural of planetarium is either planetariums or planetaria.
