Reference excerpt

Rafiqul Islam (Bengali: রফিকুল ইসলাম; 1936 – 5 March 2018) was a Bangladeshi physician and medical scientist. He is known for his assistance in the development of food saline (Orsaline) for the treatment of diarrhea. The Lancet considered this discovery to be "the most important medical discovery of the 20th century".

Early life and education Rafiqul Islam was born in 1936 in Chauddagram, Tippera district, Bengal Presidency (now Comilla District, Bangladesh). He graduated with an MBBS from Dacca Medical College in 1965. Islam later received higher education in the field of Tropical medicine and hygiene in the United Kingdom.

Career After passing MBBS, Rafiqul Islam joined the International Center for Diarrheal Disease Research, Bangladesh and retired from this institution in 2000. While working in this organization, he researched various medicines. One of his most important inventions is the food saline (Orsaline). When cholera spread in the refugee camps of West Bengal in India during the Bangladesh Liberation War in 1971, only therapeutic (intravenous) fluid was given to the vein as treatment. But due to the lack of intravenous fluid, it was possible to recover from the disease with its saline disinfected. After the independence of Bangladesh, a widespread publicity campaign was conducted on the use of saline in the treatment of diarrhea. As a result, it was also known as "Dhaka Saline". In the year 1980, the World Health Organization recognized Orsaline. Besides, Bangladeshi non-government organization BRAC played the role of spreading food saline to the remote areas of Bangladesh.

Death Islam suffered a heart attack and from old age-related ailments in February 2018. He was taken to Apollo Hospital Dhaka where he died on 5 March 2018.

Worked examples

Example 1 — a first encounter with Rafiqul Islam (scientist)

Start with the simplest possible case. Write down what Rafiqul Islam (scientist) 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 Rafiqul Islam (scientist) 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 Rafiqul Islam (scientist) 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 Rafiqul Islam (scientist)

In research: Rafiqul Islam (scientist) 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 Rafiqul Islam (scientist) 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: Rafiqul Islam (scientist) is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1936 births, 2018 deaths, Bangladeshi scientist stubs, so understanding it makes those chapters shorter.
In everyday life: Look for Rafiqul Islam (scientist) 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.
