Travel

Travel is the movement of people or objects (such as airplanes, boats, trains and other conveyances) between relatively distant geographical locations.

Etymology

The term "travel" originates from the Old French word travail. The term also covers all the activities performed during a travel (movement). A person who travels is spelled "traveler" in the United States, and "traveller" in the United Kingdom.

Purpose and motivation

"The World is a book, and those who do not travel read only a page."

Saint Augustine

Reasons for traveling include recreation, tourism or vacationing, research travel for the gathering of information, for holiday to visit people, volunteer travel for charity, migration to begin life somewhere else, religious pilgrimages and mission trips, business travel, trade, commuting, and other reasons, such as to obtain health care or fleeing war or for the enjoyment of traveling. Travel may occur by human-powered transport such as walking or bicycling, or with vehicles, such as public transport, automobiles, trains and airplanes.

Life, as the most ancient of all metaphors insists, is a journey; and the travel book, in its deceptive simulation of the journey’s fits and starts, rehearses life’s own fragmentation. More even than the novel, it embraces the contingency of things.
— Jonathan Raban (b. 1942)

Motives to travel include pleasure, relaxation, discovery and exploration, getting to know other cultures and taking personal time for building interpersonal relationships. Travel may be local, regional, national (domestic) or international. In some countries, non-local internal travel may require an internal passport, while international travel typically requires a passport and visa. A trip may also be part of a round trip, which is a particular type of travel whereby a person moves from their usual residence to one or several locations and returns.

Travel safety

It's important to take precautions to ensure travel safety. When traveling abroad, the odds favor a safe and incident-free trip, however, travelers can be subject to difficulties, crime and violence. Some safety considerations include being aware of one's surroundings, avoiding being the target of a crime, leaving copies of one's passport and itinerary information with trusted people, obtaining medical insurance valid in the country being visited and registering with one's national embassy when arriving in a foreign country. Many countries do not recognize drivers' licenses from other countries; however most countries accept international driving permits. Automobile insurance policies issued in one's own country are often invalid in foreign countries, and it's often a requirement to obtain temporary auto insurance valid in the country being visited. It's also advisable become oriented with the driving rules and regulations of destination countries. Wearing a seat belt is highly advisable for safety reasons and because many countries have penalties for violating seatbelt laws.

“ If Steam has done nothing else, it has at least added a whole new Species to English Literature ... the booklets—the little thrilling romances, where the Murder comes at page fifteen, and the Wedding at page forty—surely they are due to Steam?”
“ And when we travel by electricity—if I may venture to develop your theory—we shall have leaflets instead of booklets, and the Murder and the Wedding will come on the same page.”
— Lewis Carroll [Charles Lutwidge Dodgson] (1832–1898)

Neural Development ... Aspects of neural development Some landmarks of neural development include the birth and differentiation of neurons from stem cell precursors, the migration of immature neurons from their birthplaces in the embryo to their final positions, outgrowth of axons and dendrites from neurons, guidance of the motile growth cone through the embryo towards postsynaptic partners, the generation of synapses between these axons and their postsynaptic partners, and finally the lifelong changes in synapses, which are thought to underlie learning and memory. Typically, these neurodevelopmental processes can be broadly divided into two classes: activity-independent mechanisms and activity-dependent mechanisms...

Intergalactic Travel ... Unless the craft were capable of reaching extreme relativistic speeds, another obstacle would be to navigate the spacecraft between galaxies and succeed in reaching any chosen galaxy, star, planet or other body, as this would need an understanding of galactic movements and their coordination that is as of yet not understood. In addition, the craft would have to be of considerable size and, without reaching speeds with noteworthy relativistic effect as mentioned above, it would also need a life support system and structural design able to support human life through thousands of generations and last the millions of years required, including the propulsion system—which would have to work perfectly the millions of years after it was built to slow down the machine for its final approach...

Time Travel ...

The well organized wagon train migration began in earnest in April 1847, and the period (including the flight from Missouri in 1838 to Nauvoo) known as the Mormon Exodus is, by convention among social scientists, assumed to have ended with the completion of the First Transcontinental Railroad in 1869...
