Reference excerpt

Two and a Half Men is an American television sitcom, created by Chuck Lorre and Lee Aronsohn, that aired for 12 seasons on CBS from September 22, 2003, to February 19, 2015. The series originally starred Charlie Sheen as Charlie Harper, a hedonistic jingle writer, alongside Jon Cryer as his uptight brother Alan, and Angus T. Jones as Alan's son Jake. Supporting roles were played by Holland Taylor, Marin Hinkle, Conchata Ferrell, and Melanie Lynskey. In February 2011, CBS halted production for the rest of the eighth season after Sheen entered drug rehabilitation and made disparaging comments about Lorre. Sheen's contract was terminated the following month. Ashton Kutcher was then hired for the ninth season onward to star as Walden Schmidt, a billionaire who buys Charlie's house after Charlie's death. Angus T. Jones reduced his role starting in the 10th season, citing a religious awakening and dissatisfaction with the show's content. He later left the show, appearing only briefly in the series finale. During the later seasons, the cast expanded to include Amber Tamblyn as Jenny, Charlie's long-lost daughter, in the 11th season; Jennifer Taylor as Chelsea, Charlie’s longtime girlfriend, in the sixth and seventh seasons; and April Bowlby as Kandi, Alan’s second wife, in the third season, with recurring appearances in later seasons. Edan Alexander joined the cast as Louis, a foster child, introduced in the 12th and final season. In 2012, the show became the third-highest revenue-generating program, earning $3.24 million per episode. Ratings peaked during Sheen's tenure, saw a boost during Kutcher's first season, but gradually declined afterward, leading to the series' cancellation after the 12th season.

Worked examples

Example 1 — a first encounter with Two and a Half Men

Start with the simplest possible case. Write down what Two and a Half Men claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Two and a Half Men before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Two and a Half Men ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Two and a Half Men

In research: Two and a Half Men appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Two and a Half Men in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Two and a Half Men is common in secondary-school and first-year university syllabi. It links to neighbouring topics 2000s American multi-camera sitcoms, 2000s American sex comedy television series, 2003 American television series debuts, so understanding it makes those chapters shorter.
In everyday life: Look for Two and a Half Men outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
