Travel is the movement of people between distant geographical locations. Travel can be done by foot, bicycle, automobile, train, boat, bus, airplane, ship or other means, with or without luggage, and can be one way or round trip.
Travelling salesman problem
The travelling salesman problem asks the following question: "Given a list of cities and the distances between each pair of cities, what is the shortest possible route that visits each city and returns to the origin city?" It is an NP-hard problem in combinatorial optimization, important in operations research and theoretical computer science. The travelling purchaser problem and the vehicle routing problem are both generalizations of TSP. In the theory of computational complexity, the decision version of the TSP (where, given a length L, the task is to decide whether the graph has any tour shorter than L) belongs to the class of NP-complete problems.
A visa is a conditional authorisation granted by a territory to a foreigner, allowing them to enter, remain within, or to leave that territory. Visas typically may include limits on the duration of the foreigner's stay, areas within the country they may enter, the dates they may enter, the number of permitted visits or an individual's right to work in the country in question.
The Traveling Wilburys were a British–American supergroup consisting of Bob Dylan, George Harrison, Jeff Lynne, Roy Orbison and Tom Petty. Originating from an idea discussed by Harrison and Lynne during the sessions for Harrison's 1987 album Cloud Nine, the band formed in April 1988 after the five members united to record a bonus track for Harrison's next European single.

آرامگاه سعدی ، در سایه سار بوستان دلگشای شیراز ادبیات فارسی آسمانی خیالانگیز دارد. هر ستاره از این آسمان نوری است بیبدیل. یکی از این ستارههای پر فروغ سعدی است. ابومحمّد مُشرفالدین مُصلح بن عبدالله بن مشرّف متخلص به سعدی (۶۰۶ – ۶۹۰ هجری قمری) استاد سخن پارسی است. هر آنچه که از سعدی بهجا مانده درسی بی رقیب. او که عارفی تمام بود و اشعارش تسلی بخش روح هستند به سال ۶۹۰ هجری سر به بالین خاک نخواهد. آرامگاه سعدی باغی رویایی است در دل شیراز.
