Graphs and Charts for Light Speed, Planck's Constant and Mass
The graphs on this page were formulated to show the consistent trends in light speed, Planck's constant, and mass as measured and accepted scientifically in the years indicated. The light speed measurements are those accepted by Professor Raymond Birge until 1941 and may be referenced, along with many more, in the abundance of charts and footnotes in Atomic Constants, Light and Time.
References for the Planck particle and mass measurements are at the bottom of this page.
