Darwinism designates a distinctive form of evolutionary explanation for the history and diversity of life on earth. Its original formulation is provided in the first edition of On the Origin of Species in 1859.
The enthalpy - or internal energy - of a substance is a function of its temperature and pressure. The change in internal energy with respect to change in temperature at fixed pressure is the Specific Heat at constant pressure - cp.
h=6.626 x 10-34 J s. This comes from the work of Max Planck preformed in 1900 using blackbody radiation. There were discrete values of energy that differed by this constant. In other words, all energy is a multiple of this constant multiplied by the frequency of the wave of light. Energy is therefore quantized, it is always a multiple of a single packet of energy. Now on to the equations. Wavelength (l) and Frequency (n) Relationships. c=ln , where l is wavelength in meters.
