field particle Phys.
See gauge boson.
fine chemical Chem.
A chemical produced industrially in relatively small quantities and with a high purity. Manufacturing processes can sometimes be rather complex and produced according to the customers'
specifications. Examples are fragrances, dyes and biological and pharmaceutical products.
fine structure constant Phys.
A dimensionless number, defined as a = 2p e2/(ch) = 0.007297... which determines the strength of interactions between charged particles and electromagnetic
fields. It relates to the splitting of adsorption and emission due to interactions between orbital angular momenta and intrinsic magnetic moment (spin) of electrons in the emitting atoms. The strength of
this splitting is proportional to a2.
First Law of Thermodynamics Phys.
By making use of the conservation of energy principle, the Law relates heat to thermodynamic processes, involving transfer of heat leading to work done
to the system: DU = Q - W where Q is the heat added to the system and W is the work done by the system.
