The
PHYS menu is divided up into three sections by learning area.
These sections are:
• Chemistry
• Physics
• Quantum Physics
The contents are simply the numerical values of various physical constants that are useful in calculations and
Quantum Physics
• Planck’s constant
• Dirac’s constant
• Charge on an electron
