Well, I have been inspired to learn how to insert fancy math equations into my blog posts.  Kudos to the good folks at codecogs for providing this.  To test the power of the website, I decided to enter the Kramers-Kronig transform between the s-polarized reflectivity, Rs and the phase angle, δ.


The P stands for the Cauchy principle value and I is a constant for using this in an ATR experiment.  The value of I is given as


From this  one may go on to calculate the optical constants of a material.  Pretty cool!  My only complaint is the box that is drawn around them, but I will hold off on fixing that for now.
