This is done by dividing the objectâs mass by its volume. The formula for density is: Density = Mass / Volume. This equation can also be written: Ï=m/V. In the formula, Ï is the symbol for density. Scientists measure density in kilograms per cubic metre (kg/m3). m is the symbol for mass. Scientists measure mass in kilograms (kg).
Definition - What does Proof of Concept (POC) mean? A proof of concept (POC) is a demonstration, the purpose of which is to verify that certain concepts or theories have the potential for real-world application. POC is therefore a prototype that is designed to determine feasibility, but does not represent deliverables. Proof of concept is also known as proof of principle.
The laboratory is not a contest whose object is to get the right answer.. The purpose is to learn how to gain knowledge by looking at reality, not an attempt to make reality conform to preconceptions.
