Reference excerpt

Kurudamannil Abraham Abraham (14 March 1942 – 22 October 2021) was an Indian interventional cardiologist and a medical writer. He was a Chief Cardiologist at the Southern Railway Headquarters Hospital, Chennai, and Chief Medical Director of the Southern Railways, where he worked for 25 years.

Education and career He graduated from the Christian Medical College and Hospital, Vellore and started his career by joining the Indian Army, serving the Forces during the Indo-Pakistani War of 1971. Resuming his studies after the war, he received a degree in internal medicine and returned to Christian Medical College and Hospital in 1973. In 1978, he moved to Perambur to join the Southern Railway Headquarters Hospital, Chennai where he worked till his superannuation from government service in 2002. During his tenure, the hospital is reported to have grown to become a referral hospital which carries out over 1000 open heart surgeries every year. Dr Abraham served as the Director of Medical Service at Apollo Specialty Hospitals, Vanagaram, Chennai till his death. After his retirement from Perambur, Abraham worked as the Head of the Department of Cardiology at Fortis Malar Hospital and as a consultant cardiologist at Apollo Hospital, Chennai. He published several articles in peer reviewed national and international journals. The Government of India awarded him the fourth highest civilian award of the Padma Shri, in 1999.

Worked examples

Example 1 — a first encounter with K. A. Abraham

Start with the simplest possible case. Write down what K. A. Abraham 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 K. A. Abraham 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 K. A. Abraham 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 K. A. Abraham

In research: K. A. Abraham 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 K. A. Abraham 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: K. A. Abraham is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1942 births, 2021 deaths, 20th-century Indian surgeons, so understanding it makes those chapters shorter.
In everyday life: Look for K. A. Abraham 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.
