Reference excerpt

Sinknesh Ejigu Wolde-Mariam (born 1956) is an Ethiopian politician, chemist, businesswoman and diplomat.

Biography She was born in Ambo west of Addis Ababa to a family of eight in 1956. Her father, Ejigu Wolde-Mariam, was a military officer so the family moved around Ethiopia a lot. Both her parents did not have much education but they encouraged their children to seek a strong one. She attended several different primary schools. At the Princess Tenagnework Comprehensive High School, an Indian teacher encouraged her interest in science and chemistry. Ejigu enrolled at Addis Ababa University in 1973, where she was assigned to the mathematics department but transferred to the chemistry department in her second year. In the midst of the revolution in 1974, she was sent to the farmland to work alongside peasants. Due to the hardness of the situation in the country at the time, she dropped out of university to work teaching physical science. Later, she found work at the Ethiopian Pharmaceutical Manufacturing as a chemical analyst. After quitting her job in pharmaceuticals, she received a Bachelor of Science in Chemistry from Addis Ababa University in 1980. Ejigu became a junior geoscience analyst in the laboratory of the Ethiopian Geological Survey. She earned a master's degree in Analytical Chemistry in 1988 at the University of East Anglia. After taking her degree, she joined the Water and Geothermal Analysis Department in the Ministry of Mines and was soon promoted to head of the department, rare for a woman at the time. She became Deputy Minister of the Ministry of Mines and Energy in June 1998. She is a member of the Oromo Peoples' Democratic Organization and was a member of the House of Peoples' Representatives representing Dendi, Western Shewa, Oromia. She was appointed Minister of Mines in the Cabinet of Ethiopia in 2010. Her main role as minister was to discover the basic geoscience data of Ethiopia, to promote mineral and petroleum exploration, and grant permits to investors seeking to make money in mining. Due to her background in science, she was able to directly manage the scientific projects themselves and not just the personnel of the ministry. Throughout Ethiopia's history the government typically pursued agriculture for development, but it began focusing more on mining when Ejignu was appointed. In 2012, she was involved in a dispute with the Hong Kong-based company PetroTrans after she revoked their license since they were taking too long on a project. In 2014, she became Ethiopian Ambassador to Brazil, Argentina and Chile. Ejignu is also a Director of Ethiopian Electric Power Corporation.

Personal life She is married to a man she met at Addis Ababa University and has two children.

Worked examples

Example 1 — a first encounter with Sinknesh Ejigu

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

In research: Sinknesh Ejigu appears in chemistry 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 Sinknesh Ejigu 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: Sinknesh Ejigu is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1956 births, 20th-century Ethiopian politicians, 20th-century Ethiopian women politicians, so understanding it makes those chapters shorter.
In everyday life: Look for Sinknesh Ejigu 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.
