Exploring the Spectral Paradox

In terms of wavelength, peak solar radiation occurs at about 500 nm.  Interestingly, this is well within the range of human vision.  When solar radiation is plotted against frequency instead of wavelength, the peak is found to be at about 340 THz.  It may come as a shock that when 340 THz is converted to…

Simple Geometry, Deep Math

Introduction It is a remarkable fact that consideration of very elementary concepts in geometry often leads quickly into deep and unexpected mathematical terrain.  In high school and even college, such complexities are usually treated cursorily or omitted altogether, in order to avoid bogging down coverage of the essentials.  In this article, we delve, at least…
