Study Notes
Units of Measurement
- A quantifiable standard used to express a physical quantity.
- Provides consistency and communication across different cultures and disciplines.
International System of Units (SI)
- The modern form of the metric system, a system of measurement used globally.
- Provides a standardized framework for measuring physical quantities.
- Consists of seven base units, defining fundamental physical quantities like length, mass, and time.
International Bureau of Weights and Measures (BIPM)
- An intergovernmental organization in charge of maintaining the International System of Units (SI).
- Coordinates international metrology activities.
- Responsible for the worldwide dissemination of SI standards and the development of new units and methods for measurement.
Metrology
- The science of measurement.
- Involves all aspects of measurement, from the definition of units to the development of instruments.
- Crucial for scientific research, technological advancement, and everyday life.
Reproducibility
- Reproducibility of experimental results is central to the scientific method.
- It ensures that scientific findings are reliable and can be replicated by other scientists.
- This leads to greater confidence in the validity of scientific knowledge.
