Reference excerpt

Beginning on 24 December 2021, record rainfall across the northeastern Brazilian state Bahia resulted in severe floods, which caused the death of 21 people, injured another 358 and displaced 62,800. In a tweet, Rui Costa, the Governor of Bahia, declared the floods to be "the worst disaster that has ever occurred in the history of Bahia". 72 municipalities of Bahia declared a state of emergency. Total rainfall in the state capital Salvador during December exceeded 250 millimetres (9.8 inches) on 24 December, five times the historic average. On 26 December, the Bahia state government and Brazilian federal government, along with cooperation from other state governments, mounted a joint rescue operation for victims in the affected areas. Two dams collapsed between 25 and 26 December, at Jussiape and Itambé respectively. The town of Vitória da Conquista was heavily affected and the Catolé river in Itapetinga reached a height compared to its massive flood from 1989, leaving part of the city without energy and interrupting the potable water supply. Southern Bahia had been badly flooded earlier the same month by Subtropical Storm Ubá. COVID-19 medicines and vaccines were destroyed by the flooding.

Worked examples

Example 1 — a first encounter with Late December 2021 Bahia floods

Start with the simplest possible case. Write down what Late December 2021 Bahia floods claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, 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 Late December 2021 Bahia floods 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 Late December 2021 Bahia floods 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 Late December 2021 Bahia floods

In research: Late December 2021 Bahia floods appears in science 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 Late December 2021 Bahia floods 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.
