Many
times I have extolled the high quality of QST authors' knowledge and
writing skills.
H. Ward Silver writes the "HandsOn
Radio" column which usually features circuit and system design and
theory topics. It often includes, gasp, mathematics. His July 2013 article
is titled "Phasors, Part One." It promises to be a good series. The
last paragraph says, "There is a final way to describe the signal 
the exponential form in which it is represented as V ej^{Θ}.
This form comes from the mathematics behind Euler's equation in which
the coordinates of our points are miraculously shown to be equivalent
to ej^{Θ}=cosΘ +j sinΘ. The serious and
beautiful math behind this equation lies at the heart of much electrical
engineering and leads to the jawdropping Euler's identity: e^{jπ}
= 1 which unites the two most widely used transcendental number (e
and π),
imaginary numbers (j), negation and unity. Not bad for a moving point
in a simple circle, huh?" Beautiful. After reading it Melanie asked
why my eyes were suddenly red. "Allergies," I explained.
