A lesson is a structured period of time where learning is intended to occur. It involves one or more students (also called pupils or learners in some circumstances) being taught by a teacher or instructor. A lesson may be either one section of a textbook (which, apart from the printed page, can also include multimedia) or, more frequently, a short period of time during which learners are taught about a particular subject or taught how to perform a particular activity. Lessons are generally taught in a classroom but may instead take place in a situated learning environment.
In a wider sense, a lesson is an insight gained by a learner into previously unfamiliar subject-matter. Such a lesson can be either planned or accidental, enjoyable or painful. The colloquial phrase "to teach someone a lesson", means to punish or scold a person for a mistake they have made in order to ensure that they do not make the same mistake again.
Lessons can also be made entertaining. When the term education is combined with entertainment, the term edutainment is coined.

"Lessons" is the eighth episode of the first season of the HBO original series The Wire. The episode was written by David Simon from a story by David Simon and Ed Burns and was directed by Gloria Muzio. It originally aired on July 21, 2002.
One of Wallace's young charges wakes him for help with their math homework. Wallace appears unusually tired and irritable, but he awakes to assist with the child's school work anyway. The young kid is unable to do a simple story problem. Wallace asks a similar question, but uses the language of the drug business, instead of busses, which the kid solves in seconds. Poot shows up during the math lesson and encourages Wallace to come to work rather than lying around all day, which he has frequently been doing recently. He is reluctant and refuses to leave his room. He then asks to borrow money from Poot, who begrudgingly obliges. Afterward, Poot reports his concerns over Wallace's activities to D'Angelo, who wants to talk with Wallace face-to-face. Meanwhile, at the print shop (a Barksdale front), Stringer berates the staff for not acting like professionals.
Boxing is a martial art and combat sport in which two people throw punches at each other, usually with gloved hands. Historically, the goals have been to weaken and knock down the opponent.
Amateur boxing is both an Olympic and Commonwealth sport and is a common fixture in most international games—it also has its own World Championships. Boxing is supervised by a referee over a series of one- to three-minute intervals called rounds. The result is decided when an opponent is deemed incapable to continue by a referee, is disqualified for breaking a rule, resigns by throwing in a towel, or is pronounced the winner or loser based on the judges' scorecards at the end of the contest. In the event that both fighters gain equal scores from the judges, the fight is considered a draw (professional boxing). In Olympic boxing, due to the fact that a winner must be declared, in the case of a draw - the judges use technical criteria to chose the most deserving winner of the bout.
While people have fought in hand-to-hand combat since before the dawn of history, the origin of boxing as an organized sport may be its acceptance by the ancient Greeks as an Olympic game in BC 688. Boxing evolved from 16th- and 18th-century prizefights, largely in Great Britain, to the forerunner of modern boxing in the mid-19th century, again initially in Great Britain and later in the United States.
"Boxing" is a song from Ben Folds Five's 1995 self-titled debut album. It was written by Ben Folds. A live version appears on the 1998 album Naked Baby Photos. The song also appears in a solo version by Folds on the 2005 download-only album iTunes Originals - Ben Folds and in a symphonic version with the West Australian Symphony Orchestra on the 2005 DVD Ben Folds and WASO Live in Perth, and in an a cappella version on Ben Folds Presents: University A Cappella!.
The song was inspired by Ben Folds' father's love of boxing, and is written from the perspective of Muhammad Ali about the indecision whether or not to quit boxing professionally. The hypothetical monologue is addressed to Howard Cosell, the famous sports announcer who covered boxing matches of that era.
Bette Midler covered the song on her 1998 album Bathhouse Betty. Jon Foreman of Switchfoot covered the song on a rare cover compilation only found on the internet entitled Songs By Other Folk.
In computer science, an object type (a.k.a. wrapping object) is a datatype which is used in object-oriented programming to wrap a non-object type to make it look like a dynamic object.
Some object-oriented programming languages make a distinction between reference and value types, often referred to as objects and non-objects on platforms where complex value types don't exist, for reasons such as runtime efficiency and syntax or semantic issues. For example, Java has primitive wrapper classes corresponding to each primitive type: Integer
and int
, Character
and char
, Float
and float
, etc. Languages like C++ have little or no notion of reference type; thus, the use of object type is of little interest.
Boxing, otherwise known as wrapping, is the process of placing a primitive type within an object so that the primitive can be used as a reference object. For example, lists may have certain methods which arrays might not, but the list might also require that all of its members be dynamic objects. In this case, the added functionality of the list might be unavailable to a simple array of numbers.
For a more concrete example, in Java, a LinkedList
can change its size, but an array must have a fixed size. One might desire to have a LinkedList
of int
s, but the LinkedList
class only lists references to dynamic objects — it cannot list primitive types, which are value types.
