Kaththi

Kaththi 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 Kaththi rather than just read about it. In short: Kaththi (transl. Knife) is a 2014 Indian Tamil-language action drama film written and directed by A.

Key takeaways

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

Reference excerpt

Kaththi (transl. Knife) is a 2014 Indian Tamil-language action drama film written and directed by A. R. Murugadoss. It is produced by Allirajah Subaskaran's Lyca Productions. The film stars Vijay in a dual role alongside Samantha, Neil Nitin Mukesh (in his Tamil debut), and Sathish. In the film, a petty thief assumes the identity of his lookalike and attempts to lead a rebellion by farmers from the latter's village, Thanoothu, and helps them fight against an entrepreneur who exploited Thanoothu's water resources. The film was officially announced in November 2013, and principal photography took place between February and September 2014. Primarily shot across Chennai, it was also filmed in Kolkata, Mumbai, Hyderabad, Rajahmundry, Begumpet, Nellore, and Kadapa. The cinematography was handled by George C. Williams, and the film was edited by A. Sreekar Prasad. The music is composed by Anirudh Ravichander. The film marks the Tamil debuts of Mukesh and Chowdhury. Made on a budget of ₹50 crore, Kaththi was released worldwide on 22 October 2014, coinciding with Diwali, and received critical acclaim. Before the film's release, it faced controversies for plagiarism allegations, and the business link of Subaskaran, the film's producer, with Sri Lankan president Mahinda Rajapaksa, which resulted in Tamil fringe groups protesting against the film. Despite this, the film was a major commercial success, grossing ₹128 crore (equivalent to ₹205 crore or US$21 million in 2023), and was remade into Telugu as Khaidi No. 150 (2017). Kaththi is the second highest-grossing Tamil movie of 2014. A recipient of various accolades, the film won three out of seven nominations at the Filmfare Awards South, including the Filmfare Award for Best Film – Tamil. It won four South Indian International Movie Awards (including Best Film) and two Vijay Awards (Favourite Film and Favourite Director for Murugadoss). Additionally, the film won an IIFA Utsavam and Ananda Vikatan Cinema Awards each, three Edison Awards and a nomination for Best Social Awareness at the Norway Tamil Film Festival Awards before eventually losing to Sigaram Thodu (2014).

Illustrations

Subaskaran Allirajah, who produced Kaththi under Lyca Productions, was alleged to have business links with Sri Lankan politician Mahinda Rajapaksa.[113] Allirajah, however refuted such claims in several instances.[114]

Worked examples

Example 1 — a first encounter with Kaththi

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

In research: Kaththi 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 Kaththi 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: Kaththi is common in secondary-school and first-year university syllabi. It links to neighbouring topics 2010s business films, 2010s vigilante films, 2011 controversies, so understanding it makes those chapters shorter.
In everyday life: Look for Kaththi 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.
