Key takeaways

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

Reference excerpt

Reuben David (19 September 1912 – 24 March 1989) was a zoologist and the founder of the Kankaria Zoo in Ahmedabad, Gujarat, India.

Biography He was born into a Bene Israel Jewish family in Ahmedabad. He was the youngest son of Joseph David. He was a self-taught veterinarian. He was invited by the Ahmedabad Municipal Corporation in 1951 to create a zoo in the city. He also founded the Kankaria Zoo (now Kamala Nehru Zoological Garden), the Chacha Nehru Balvatika (Children's Park) and the Natural History Museum, later named after him. He had lost his speech due to cancer. He also served as an advisor for Sundervan in Ahmedabad and Indroda Park in Gandhinagar. He co-authored The Asiatic Lion (1991) with M. A. Rashid who was a retired chief conservator of forests under Government of Gujarat. He was the Fellow of the Zoological Society (FZS). He was honoured with the Padma Shri by the Government of India in 1975. Australian anthropologist Colin Groves discovered the prehistoric warthog in 1981 and named the Central Asian boar after him, Sus scrofa davidi.

Personal life Author Esther David is his daughter.

Worked examples

Example 1 — a first encounter with Reuben David

Start with the simplest possible case. Write down what Reuben David claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In biology, 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 Reuben David 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 Reuben David 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 Reuben David

In research: Reuben David appears in biology 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 Reuben David 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: Reuben David is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1912 births, 1989 deaths, 20th-century Indian Jews, so understanding it makes those chapters shorter.
In everyday life: Look for Reuben David 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.
