Measurements
Whether its physics, biology, or chemistry, all science requires some form of numerical analysis. Knowing how to measure is one of the most fundamental concepts that a scientist is supposed to have. Standardized measurements help to define relationships between factors. This picture is of a commonplace ruler. Like most American rulers, one side is divided into twelve inches and the other consists of thirty centimeters. The metric system, which measures length in terms of meters, is known to be the universal one and used extensively by those in the scientific field. Rulers are used to find distances betwen points and dimensions of objects. Sometimes, time and length are connected to each other. For instance, as time passes by, the length of a plant can increase. Although science is meant to find changes in order to get a better grasp of the world, the utensils used to find them are consistent.
