Scientific notation produces convenient numbers when working with very small or very large quantities.
Scientists use scientific notation to compute very large or very small numbers.
telescope
A general answer to your question would be: tools. For example, a microscope is a tool that makes it easier to understand things that are too small to observe directly. An x-ray machine is a tool that allows us to see inside of things that are too hard to see inside of directly. A knife is a tool that allows us to cut up large things to see what is inside of them.
Scientists use the concepts of scale and magnitude to explain phenomena that are very small or very large. These concepts help put the size of objects or events into perspective by comparing them to familiar objects or distances. Scientists also use scientific notation to express very large or very small numbers in a more manageable way.

Small bacause if you have large you could hear things you are not supposed to
a model.
To make distant things closer they use a telescope, to make close things larger they use a sense or magnifying glass, to make very small things larger they use a microscope. to make incredibly small things clearer they use mathematics.

Scientists use the concept of scale to help explain things that are very small or very large. They may use measurements in nanometers or micrometers for tiny objects, and in astronomical units or light-years for massive objects to provide a sense of scale. Additionally, they often employ models and visualizations to illustrate these concepts in a more understandable way.
they measure it by measuring 20 of them and then divide only 1 of it by the answer they got from the 20.
