Picogram
A picogram (pg) is a unit of mass equal to one trillionth (10^-12) of a gram.
History/Origin
The picogram was introduced as part of the metric system to measure extremely small masses, especially in scientific and laboratory contexts, as a subdivision of the gram in the SI unit system.
Current Use
Picograms are used in scientific fields such as biology, chemistry, and physics to measure very small quantities of substances, including DNA, proteins, and other microscopic materials.
Proton Mass
The proton mass (m_p) is the mass of a proton, a subatomic particle found in the nucleus of an atom, approximately 1.6726219 × 10⁻²⁷ kilograms.
History/Origin
The proton mass was first measured in the early 20th century through experiments involving atomic and nuclear physics, notably by Ernest Rutherford and subsequent researchers refining the value through scattering experiments and mass spectrometry.
Current Use
The proton mass is used as a fundamental constant in physics and chemistry, serving as a standard unit of mass in atomic and nuclear calculations, and is essential in defining atomic mass units and understanding nuclear reactions.
