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.
Nanogram
A nanogram (ng) is a unit of mass equal to one billionth (10^-9) of a gram.
History/Origin
The nanogram was introduced as part of the metric system to measure extremely small quantities, especially in scientific and medical fields, as the need for precise measurement of tiny masses grew with technological advancements.
Current Use
Nanograms are commonly used in scientific research, pharmaceuticals, and environmental testing to measure very small amounts of substances accurately.
