pattern
Definition
A pattern is a regular or repeated sequence of events or objects. Patterns can be found in nature, in physics, and in mathematics.
Some examples of patterns in nature include the seasons, the tides, and the orbits of planets. Some examples of patterns in physics include the laws of motion, the laws of thermodynamics, and the laws of electromagnetism. Some examples of patterns in mathematics include the Fibonacci sequence, the golden ratio, and the Pythagorean theorem.
Patterns can be used to make predictions about the future. For example, we can predict when the next season will change by looking at the patterns of the seasons in the past. We can predict the tides by looking at the patterns of the tides in the past. We can predict the orbits of planets by looking at the patterns of the orbits of planets in the past.
Patterns are a fundamental part of science. They help us to understand the world around us and to make predictions about the future. Pattern recognition is a valuable skill for scientists and engineers.
How can the word be used?
The quilt was made up of a patchwork of different patterns.
Different forms of the word
Noun:
- pattern (a repeated or regular arrangement of shapes, colours, or other elements).
- patterned (having a pattern).
- patterning (the act of creating a pattern).
Verb:
- to make or form a pattern.
- to arrange something in a pattern.
Etymology
The word "pattern" is derived from the Old French word "patron", which means "model, example". The first recorded use of the word "pattern" in English was in the 14th century.

What patterns can you see around you?
AQA Science Exam Question and Answer
Question:
Discuss the concept of patterns in scientific observations. Provide examples of patterns in nature or scientific phenomena and explain how recognising and analysing patterns contributes to scientific understanding and predictions.
Answer:
Patterns are essential elements in scientific observations that provide valuable insights into natural phenomena and allow us to make predictions. One example of a pattern is the changing seasons. The regular shift from winter to spring to summer and then to fall follows a predictable pattern based on the Earth's orbit around the Sun.
Another example is the periodic table in chemistry, where elements are organised based on their properties and atomic numbers. This arrangement reveals patterns in properties like reactivity, allowing scientists to predict the behaviour of elements that haven't yet been discovered.
Recognising and analysing patterns is crucial in scientific understanding and prediction. Identifying patterns can lead to the formulation of hypotheses, which can then be tested through experimentation. Patterns help scientists make educated guesses about the behaviour of systems, guiding further research and exploration.
Moreover, pattern recognition has led to breakthroughs in fields like genetics, where DNA sequences are analysed for patterns that indicate the presence of specific genes or mutations. This understanding aids in medical diagnoses and genetic engineering.
