Attogram
An attogram (ag) is a unit of mass equal to 10^-18 grams, used to measure extremely small quantities.
History/Origin
The attogram was introduced as part of the metric system's expansion to include smaller units for scientific measurements, particularly in fields like nanotechnology and molecular biology, during the 20th century.
Current Use
Attograms are primarily used in scientific research to quantify very small masses, such as individual molecules or nanoparticles, and are part of the SI units for precise measurements in advanced scientific applications.
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.
