Kliti Grice

Kliti Grice 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 Kliti Grice rather than just read about it. In short: Kliti Grice is an Australian chemist and geochemist known for her work in identifying geological and environmental causes for mass extinction events. Her research integrates geological information with data on molecular fossils and their stable carbon, hydrogen and sulfur isotopic compositions to reconstruct details of microbial, fungal and floral inhabitants of modern and ancient aquatic environments and biodiversi…

Key takeaways

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

Reference excerpt

Kliti Grice is an Australian chemist and geochemist known for her work in identifying geological and environmental causes for mass extinction events. Her research integrates geological information with data on molecular fossils and their stable carbon, hydrogen and sulfur isotopic compositions to reconstruct details of microbial, fungal and floral inhabitants of modern and ancient aquatic environments and biodiversity hot spots. This information expands our understanding of both the Earth's history and its current physical state, with implications ranging from energy and mineral resource exploration strategies to environmental sustainability encompassing climate dynamics and expected rates, durations and scale of our future planet's health. As one of the youngest women professors in Earth Sciences, she is the founding director of the Western Australian Organic and Isotope Geochemistry Centre (WA-OIGC) and is a Professor of Organic and Isotope Geochemistry at Curtin University in Perth, Western Australia.

Early life and education Kliti Grice obtained her PhD in 1995 at the University of Bristol (UK). Grice's PhD research measured and interpreted the stable carbon isotopic compositions of maleimides (small, polar, nitrogen-containing molecules) in sedimentary organic matter from the Permian Kupferschiefer (highly anoxic Zechstein Sea, NW Germany). These compounds are unique to the chlorophylls of photosynthetic algae and bacteriochlorophylls of anoxygenic photosynthetic green sulfur bacteria (Chlorobi) – a discovery that has underpinned some of her latter breakthroughs. From November 1995 to February 1998, Kliti undertook a post-doctoral fellowship (100% research) at the Royal Netherlands Institute for Sea Research under the guidance of Jaap Sinninghe Damsté (Member of the Royal Netherlands Academy of Arts and Sciences; and Spinoza Prize winner - The Netherlands' highest science research award). During her postgraduate research, Kliti was mentored by Professor James R Maxwell (FRS; former co-editor-in-chief of Organic Geochemistry) and the late Prof. Geoffrey Eglinton (FRS; recipient of the Royal medal, Dan David Prize and NASA gold medal). Other important career mentors include: Roger Summons (MIT, USA; formerly Chief Researcher at Geoscience Australia), FRS, FAA, Fellow American Geophysical Union; the late Prof. John de Laeter (legacy includes John de Laeter Centre-JDLC at CU); and Roland de Marco (Deputy VC Research at University of the Sunshine Coast, Queensland; formerly Head of Department of Chemistry and Dean of Research at CU).

Worked examples

Example 1 — a first encounter with Kliti Grice

Start with the simplest possible case. Write down what Kliti Grice 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 Kliti Grice 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 Kliti Grice 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 Kliti Grice

In research: Kliti Grice 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 Kliti Grice 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: Kliti Grice is common in secondary-school and first-year university syllabi. It links to neighbouring topics Alumni of the University of Bristol, Australian women scientists, Fellows of the Australian Academy of Science, so understanding it makes those chapters shorter.
In everyday life: Look for Kliti Grice 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.
