Learning significant figures can be difficult in science. But, there is a reason to learn them. Scientists and engineers use significant figures to show how accurate their measurements are and how accurate the instruments used to collect the measurements are.

The atom is the basic building block of matter and is an important topic an all science courses. The atoms if made of a nucleus at its center, consisting of protons (positively charged particles) and neutrons (neutrally charged particles). The nucleus contains all of the mass of the atom, so the atomic mass is the number of neutrons plus the number of protons (labeled in Atomic Mass Units, AMU).The number of protons present in...

Understanding the principles of Dimensional Analysis is not only an important skill in science it is also something you will use in your daily life, for the rest of your life. Once you learn the rules and the process of dimensional analysis, you will be able to convert anything in life - just stick with the three simple rules:

 Being able to convert units between English and Metrics (and System International) is a fundamental concept in science. The common language in science is the System International (which is very similar to the metric system) and all scientists use these units as a standard. However, some regions of the world (like the Un...
