##  Note: In ruby the notation x**n means x raised to the nth power

##  In linear algebra, Dual numbers are in the form:
##  a + bε
##  
##  Where ε is what is called nilpotent, you can think of
##  ε as an infinitesimal (sort of kinda), like how they used to do Calculus in the
##  olden days.

For although light oftenest behaves as a wave, it can be looked on as a mote, the *lightbit*. 

We have already said by the way that a mote of stuff can behave not only as a chunk, but as a wave. 

Down among the unclefts, things do not happen in steady flowings, but in leaps between bestandings that are forbidden. 

The knowledge-hunt of this is called *lump beholding*.
