Jo-Anne Sewlal

Jo-Anne Sewlal 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 Jo-Anne Sewlal rather than just read about it. In short: Jo-Anne Nina Sewlal (29 March 1979 - 20 January 2020) was a Trinidad and Tobago arachnologist. She discovered several new species of spiders in Trinidad and Tobago, and published some of the first surveys of spider populations in many countries of the Caribbean.

Key takeaways

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

Reference excerpt

Jo-Anne Nina Sewlal (29 March 1979 - 20 January 2020) was a Trinidad and Tobago arachnologist. She discovered several new species of spiders in Trinidad and Tobago, and published some of the first surveys of spider populations in many countries of the Caribbean.

Biography Jo-Anne Nina Sewlal was born in Point Fortin on 29 March 1979. In 1999, she began her Bachelor of Science in Zoology at the University of the West Indies at St. Augustine. She completed her MPhil in Entomology from the same university in 2005, and continued on to a PhD in Arachnology. As a PhD student, Sewlal won a research award from the Royal Entomological Society (2008), an International Darwin Scholarship (2009) from the Field Studies Council, and a NIHERST 2012 Award for Excellence in Science and Technology (Junior Scientist category). She was invited by the Smithsonian Institution in 2008 to identify its collection of spiders from Tobago. She completed her PhD under the advice of Adrian Hailey in 2013. After graduation, Sewlal became a lecturer at UWI St. Augustine. In her field work, she surveyed spider populations in Anguilla, Montserrat, St. Kitts and Nevis, Grenada, Antigua and St. Lucia; for several countries, this was the first arachnid survey. Her work was also featured on the Science Channel. Sewlal was involved with the NGO Environment Tobago, and wrote columns for it in the Tobago News. She was also an active member of the Trinidad and Tobago Field Naturalists' Club (TTFNC). She led the searches for new spider species in the TTFNC's annual BioBlitz. As a lecturer, she cofounded the Point Fortin Chess Centre to introduce the game to schoolchildren. She served as the Secretary of the Trinidad and Tobago chapter for the Caribbean Academy of Sciences at the time of her death. Sewlal died of an allergic reaction at the Port of Spain General Hospital on 20 January 2020.

Worked examples

Example 1 — a first encounter with Jo-Anne Sewlal

Start with the simplest possible case. Write down what Jo-Anne Sewlal 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 Jo-Anne Sewlal 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 Jo-Anne Sewlal 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 Jo-Anne Sewlal

In research: Jo-Anne Sewlal 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 Jo-Anne Sewlal 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: Jo-Anne Sewlal is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1979 births, 2020 deaths, 21st-century zoologists, so understanding it makes those chapters shorter.
In everyday life: Look for Jo-Anne Sewlal 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.
