Ghostbusters

Ghostbusters is a science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Ghostbusters rather than just read about it. In short: Ghostbusters is a 1984 American supernatural comedy film directed by Ivan Reitman and written by Dan Aykroyd and Harold Ramis. It stars Bill Murray, Aykroyd, and Ramis as Peter Venkman, Ray Stantz, and Egon Spengler, three eccentric parapsychologists who start a ghost-catching business in New York City.

Key takeaways

Ghostbusters belongs to science; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Ghostbusters to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Ghostbusters from memory before moving on to harder problems.

Reference excerpt

Ghostbusters is a 1984 American supernatural comedy film directed by Ivan Reitman and written by Dan Aykroyd and Harold Ramis. It stars Bill Murray, Aykroyd, and Ramis as Peter Venkman, Ray Stantz, and Egon Spengler, three eccentric parapsychologists who start a ghost-catching business in New York City. It also stars Sigourney Weaver and Rick Moranis, and features Annie Potts, Ernie Hudson, and William Atherton in supporting roles. Based on his fascination with spirituality, Aykroyd conceived Ghostbusters as a project starring himself and John Belushi, in which they would venture through time and space battling supernatural threats. Following Belushi's death in 1982, and with Aykroyd's concept deemed financially impractical, Ramis was hired to help rewrite the script to set it in New York City and make it more realistic. It was the first comedy film to employ expensive special effects, and Columbia Pictures, concerned about its relatively high $25–30 million budget, had little faith in its box office potential. Filming took place from October 1983 to January 1984, in New York City and Los Angeles. Due to competition for special effects studios among various films in development at the time, Richard Edlund used part of the budget to found Boss Film Studios, which employed a combination of practical effects, miniatures, and puppets to deliver the ghoulish visuals. Ghostbusters was released on June 8, 1984, by Columbia Pictures, to critical acclaim and became a cultural phenomenon. It was praised for its blend of comedy, action, and horror, and Murray's performance was often singled out for praise. It earned at least $282 million worldwide during its initial theatrical run and was the second-highest-grossing film of 1984 in the United States and Canada, and the then-highest-grossing comedy ever. It was the number-one film in US theaters for seven consecutive weeks and one of only four films to gross more than $100 million that year. Further theatrical releases have increased the worldwide total gross to around $370 million, making it one of the most successful comedy films of the 1980s. In 2015, the Library of Congress selected it for preservation in the National Film Registry. Its theme song, "Ghostbusters" by Ray Parker Jr., was also a number-one hit. With its effect on popular culture, and a dedicated fan following, the success of Ghostbusters launched a multi-billion dollar multimedia franchise. This included the popular animated television series The Real Ghostbusters (1986), its follow-up Extreme Ghostbusters (1997), video games, board games, comic books, clothing, music, and haunted attractions. Ghostbusters was followed in 1989 by Ghostbusters II, which fared less well financially and critically, and attempts to develop a second sequel paused in 2014 following Ramis's death. After a 2016 reboot received mixed reviews and underperformed financially, a second sequel to the 1984 film, Ghostbusters: Afterlife (2021), was released, followed by Ghostbusters: Frozen Empire (2024).

Worked examples

Example 1 — a first encounter with Ghostbusters

Start with the simplest possible case. Write down what Ghostbusters 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 Ghostbusters 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 Ghostbusters 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 Ghostbusters

In research: Ghostbusters 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 Ghostbusters 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: Ghostbusters is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1980s demon films, 1980s ghost films, 1984 American films, so understanding it makes those chapters shorter.
In everyday life: Look for Ghostbusters 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.
