Femtogram
A femtogram (fg) is a unit of mass equal to 10^-15 grams.
History/Origin
The femtogram was introduced as part of the metric system's extension to measure extremely small masses, particularly in scientific fields such as chemistry and biology, during the 20th century as measurement technology advanced.
Current Use
Femtograms are used in scientific research to measure tiny quantities of substances, such as in molecular biology, nanotechnology, and materials science, where precise measurement of very small masses is required.
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.
