The Negative of a Math Photo

January 13, 2017

This beautiful example of single point perspective is printed as a negative image digitally.  The concept of a negative in math can be related to negative in photography if we think of it in terms of “opposite.”  This could be a teaching aid.




Math in Architechture

The U. S. Air Force Academy Chapel in Colorado Springs  is an example of a very mathematical theme in architecture.  Symmetry, geometry along with the theme of jet aircraft.


Single Point Perspective Photo– Congressional Office Building

August 4, 2016

Congressional Office Building

This picture was taken in a hall of the Cannon House Office Building where Representatives in Congress have their offices.  The building was completed in 1908.

It is a good example of single point perspective, also known as one point perspective.  For more on this subject, which overlaps math and art, go to:

Double Rainbow Picture and Explanation

May 2, 2016

Rainbows are frequently created by the sun shining into an atmosphere with rain droplets, when the sun is low in the sky.  Each droplet of water acts like a prism breaking up the sun’s white light into the colors of the rainbow.  Less frequently, an observer can see a double rainbow, in which the second rainbow is higher in the sky, more faint, and with the colors of the primary rainbow reversed.  The prism effect is created by the reflection and refraction of the light by the droplets.

For a more detailed explanation see:

Geometric Perspective Based Optical Illusion

December 4, 2012

Optical illusions and perspective are part of understanding geometry.  The attached link to a video is probably the best I have ever seen.
