Mechai Viravaidya

Mechai Viravaidya is a astronomy 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 Mechai Viravaidya rather than just read about it. In short: Mechai Viravaidya (born 17 January 1941, Thai: มีชัย วีระไวทยะ; RTGS: Michai Wirawaithaya) is a former politician and activist in Thailand known for promoting condoms, family planning, and AIDS awareness. Since the 1970s, Mechai has been affectionately called "Mr.

Key takeaways

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

Reference excerpt

Mechai Viravaidya (born 17 January 1941, Thai: มีชัย วีระไวทยะ; RTGS: Michai Wirawaithaya) is a former politician and activist in Thailand known for promoting condoms, family planning, and AIDS awareness. Since the 1970s, Mechai has been affectionately called "Mr. Condom", and condoms are often referred to as "mechais" in Thailand. From the time that he began his work, the average number of children in Thai families has decreased from 7 to 1.5. He has been credited with leading efforts that improved the lives of millions of people.

Early life Viravaidya was born in Bangkok to a Scottish mother and a Thai father, both of whom were doctors and had met while studying in Edinburgh. He is one of four children. His younger brother, Sunya, is the founder of the Pattaya International Hospital. One of his sisters, Sumalee Viravaidya, was a journalist in the 1970s, writing for the Bangkok Post and The Nation. Viravaidya was educated in Australia at Geelong Grammar School and at Trinity College of the University of Melbourne, where he obtained a Bachelor of Commerce degree. In 1965, he returned to Thailand and in 1966, he started to work in family planning, emphasizing the use of condoms. In 1973, he left the civil service and founded a nonprofit service organization, the Population and Community Development Association (PDA), to continue his efforts to improve the lives of the rural poor. He used such events as condom-blowing contests for schoolchildren, encouraging taxi drivers to hand out condoms to their customers, and founding a restaurant chain called Cabbages and Condoms, where condoms were given to customers with the bill. Next to the original restaurant, in Bangkok, there is a family planning clinic, one of several places in the Thai capital where poor women can receive pregnancy termination, a practice that is legal in the country per Section 305 of the Thai penal code but often perceived as illegal. The clinic is permitted by the authorities due to the dangers of unsafe abortion caused by economic difficulties.

Later life

Viravaidya served as deputy minister of industry from 1985 to 1986, under prime minister Prem Tinsulanonda. He later served as senator from 1987 until 1991. During this time, AIDS appeared in Thailand, and he increased his efforts to promote sexual-safety awareness. A military coup in 1991 installed prime minister Anand Panyarachun, who then appointed Viravaidya minister for tourism, information, and AIDS. He was able to start a large, successful AIDS education campaign and served until 1992. At that time, he became the chairman of the Foundation for International Education, a nonprofit organization that serves as the governing body of the NIST International School. Viravaidya continued to serve as chair until stepping down in May 2002. In 1995, he was appointed an honorary officer of the Order of Australia, for "service to Australian-Thai relations and contributions to the world AIDS debate". In 2004, Viravaidya again became a senator. In 2006, he won praise from the toilet industry (but criticism from the retail industry) for proposing that retailers be obliged to build a public toilet for every ten square metres of retail space. As of 2007, Viravaidya continued to oversee rural development and health initiatives as the chairman of PDA, now the largest NGO in Thailand, with 600 employees and 12,000 volunteers. On 29 May 2007, PDA was awarded the Bill & Melinda Gates Foundation's Gates Award in recognition of its pioneering work in family planning and HIV/AIDS prevention. This award came with a grant of $1,000,000.

Worked examples

Example 1 — a first encounter with Mechai Viravaidya

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

In research
Mechai Viravaidya appears in astronomy 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 Mechai Viravaidya 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
Mechai Viravaidya is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1941 births, Government spokespersons of Thailand, HIV/AIDS activists, so understanding it makes those chapters shorter.
In everyday life
Look for Mechai Viravaidya 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.
