A book is a medium for recording information in the form of writing or images. Modern books are typically in codex format, composed of many pages that are bound together and protected by a cover; they were preceded by several earlier formats, including the scroll and the tablet. The book publishing process is the series of steps involved in their creation and dissemination.

As a conceptual object, a book refers to a written work of substantial length, which may be distributed either physically or digitally as an ebook. These works can be broadly classified into fiction (containing invented content, often narratives) and non-fiction (containing content intended as factual truth). A physical book may not contain such a work: for example, it may contain only drawings, engravings, photographs, puzzles, or removable content like paper dolls. It may also be left empty for personal use, as in the case of account books, appointment books, autograph books, notebooks, diaries and sketchbooks.

Books are sold at both regular stores and specialized bookstores, as well as online for delivery, and can be borrowed from libraries. The reception of books has led to a number of social consequences, including censorship.

The modern book industry has seen several major changes due to new technologies, including ebooks and audiobooks (recordings of books being read aloud). Awareness of the needs of print-disabled people has led to a rise in formats designed for greater accessibility, such as braille printing and large-print editions. Google Books estimated in 2010 that approximately 130 million total unique books had been published.

Friends is an American television sitcom created by David Crane and Marta Kauffman, which aired on NBC from September 22, 1994, to May 6, 2004, lasting ten seasons. With an ensemble cast starring Jennifer Aniston, Courteney Cox, Lisa Kudrow, Matt LeBlanc, Matthew Perry and David Schwimmer, the show revolves around six friends in their 20s and early 30s who live in Manhattan, New York City. The original executive producers were Kevin S. Bright, Kauffman, and Crane.

Kauffman and Crane began developing Friends under the working title Insomnia Cafe between November and December 1993. They presented the idea to Bright, and together they pitched a seven-page treatment of the show to NBC. After several script rewrites and changes, including title changes to Six of One and Friends Like Us, the series was finally named Friends. Filming took place at Warner Bros. Studios in Burbank, California. The series was produced by Bright/Kauffman/Crane Productions and Warner Bros. Television.

The show ranked within the top ten of the final television season ratings; it ultimately reached the number-one spot in its eighth season. The series finale aired on May 6, 2004, and was watched by around 52.5 million American viewers, making it the fifth-most-watched series finale in television history and the most-watched television episode of the 2000s. Friends received acclaim throughout its run, becoming one of the most popular television shows of all time. The series was nominated for 62 Primetime Emmy Awards, winning the Outstanding Comedy Series award in 2002 for its eighth season. The show ranked no. 21 on TV Guide's 50 Greatest TV Shows of All Time, and no. 5 on Empire magazine's The 50 Greatest TV Shows of All Time. In 1997, the episode "The One with the Prom Video" was ranked no. 100 on TV Guide's 100 Greatest Episodes of All-Time. In 2013, Friends ranked no. 24 on the Writers Guild of America's 101 Best Written TV Series of All Time, and no. 28 on TV Guide's 60 Best TV Series of All Time. The sitcom's cast members returned for Friends: The Reunion, a reunion special which was released on HBO Max on May 27, 2021.

Leapfrog is a children's game in which players vault over each other's stooped backs.

Learning is the process of acquiring new understanding, knowledge, behaviors, skills, values, attitudes, and preferences. The ability to learn is possessed by humans, non-human animals, and some machines; there is also evidence for some kind of learning in certain plants. Some learning is immediate, induced by a single event (e.g. being burned by a hot stove), but much skill and knowledge accumulate from repeated experiences. The changes induced by learning often last a lifetime, and it is hard to distinguish learned material that seems to be "lost" from that which cannot be retrieved.

Human learning starts at birth (it might even start before) and continues until death as a consequence of ongoing interactions between people and their environment. The nature and processes involved in learning are studied in many established fields (including educational psychology, neuropsychology, experimental psychology, cognitive sciences, and pedagogy), as well as emerging fields of knowledge (e.g. with a shared interest in the topic of learning from safety events such as incidents/accidents, or in collaborative learning health systems). Research in such fields has led to the identification of various sorts of learning. For example, learning may occur as a result of habituation, or classical conditioning, operant conditioning or as a result of more complex activities such as play, seen only in relatively intelligent animals. Learning may occur consciously or without conscious awareness. Learning that an aversive event cannot be avoided or escaped may result in a condition called learned helplessness. There is evidence for human behavioral learning prenatally, in which habituation has been observed as early as 32 weeks into gestation, indicating that the central nervous system is sufficiently developed and primed for learning and memory to occur very early on in development.

Play has been approached by several theorists as a form of learning. Children experiment with the world, learn the rules, and learn to interact through play. Lev Vygotsky agrees that play is pivotal for children's development, since they make meaning of their environment through playing educational games. For Vygotsky, however, play is the first form of learning language and communication, and the stage where a child begins to understand rules and symbols. This has led to a view that learning in organisms is always related to semiosis, and is often associated with representational systems/activity.
