Reference excerpt

Roseli Ocampo-Friedmann (November 23, 1937 – September 4, 2005) was a Filipino-American microbiologist and botanist who specialized in the study of cyanobacteria and extremophiles. Her work has been cited in work exploring the terraforming of Mars.

Biography Ocampo-Friedmann was born Roseli Ocampo on November 23, 1937 in Manila, Philippines to Eliseo and Generosa Ocampo. She earned a degree in botany from the University of the Philippines in 1958. After completing her master's at Hebrew University in Jerusalem in 1966, she returned to the Philippines to work for Manila's National Institute of Science and Technology. In 1968, she joined Dr. Imre Friedmann at Florida State University where she received her PhD in 1973. Roseli married Friedmann in 1974. In 1987, she became a professor at Florida A&M University in Tallahassee, while working summers at Florida State University with Friedmann. Later in her career, she served as a scientific consultant for the SETI Institute. Together with her husband, the couple traveled internationally to study algae and other microorganisms. In the mid-1970s, the couple went to the Ross Desert in the Dry Valleys region of Antarctica, where the mountain ranges were thought to be lifeless. They were a frigid, arid area mostly without ice or snow. These microorganisms (called cryptoendoliths) would tolerate the cold and in the summer thaw, rehydrate, and photosynthesize, and were able to colonize the Beacon sandstone. After successfully culturing them in the laboratory with her "blue-green thumb", the couple wrote an article detailing their discovery on September 24, 1976. This work was cited by NASA and Walter Cronkite as the basis for life on Mars when the Viking 1 spacecraft touched down on the planet on July 20, 1976 as the planet has similar conditions. Friedmann Peak, in the Darwin Mountains of Antarctica, where she co-discovered endolithic microorganisms in the Beacon sandstone, is named after her. The National Science Foundation awarded her the Antarctic Service Medal in 1981. During her lifetime, she collected over 1,000 types of microorganisms from extreme environments around the world. Ocampo-Friedmann died September 4, 2005, of Parkinson's disease in Kirkland, Washington.

Worked examples

Example 1 — a first encounter with Roseli Ocampo-Friedmann

Start with the simplest possible case. Write down what Roseli Ocampo-Friedmann 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 Roseli Ocampo-Friedmann 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 Roseli Ocampo-Friedmann 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 Roseli Ocampo-Friedmann

In research: Roseli Ocampo-Friedmann 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 Roseli Ocampo-Friedmann 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: Roseli Ocampo-Friedmann is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1937 births, 2005 deaths, 20th-century American scientists, so understanding it makes those chapters shorter.
In everyday life: Look for Roseli Ocampo-Friedmann 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.
