Since our founding in early 1998, Earthlogic has worked to create a paperless environment. We believe in the use of electronic medium for communication. Unless otherwise requested, we produce all business forms, including invoices, in Adobe PDF format and use email for delivery. This saves on cost of materials and mailing, not to mention a few trees. We do have a printed brochure which is printed on 100% recycled paper. We also encourage our clients to use recycled paper for printed materials whenever possible.
So what’s with recycled electrons? While we’re not introducing anything new in the field of physics, we thought it would be an interesting way to introduce recycling, and to have a little fun by providing a discussion of the science behind how we see light and color which is tied in with the idea of recycling electrons. We’ll get to light and color shortly. First, a few basics from physics.
Definitions
An atom is a unit of matter, the smallest unit of an element, having all the characteristics of that element and consisting of a dense, central, positively charged nucleus surrounded by a system of negatively charged electrons.
An electron is a sub-atomic particle with a negative charge. A flow of electrical current consists of the unidirectional (on average) movement of many electrons. The more mobile electrons are in a given material, the greater it electrical conductance (or equivalently, the lower its resistance). When an atom is energized, electrons will move farther from the nucleus of the atom and then fall back into its neutral position. When this happens a single photon is produced.
A photon is a unit of retinal illumination, equal to the amount of light that reaches the retina through 1 square millimeter of pupil area from a surface having a brightness of 1 candela per square meter.
OK, backing up, when you are visiting our web site, you are using electronic devices that use conducted electricity (via electrons) and you see the physical results of charging those electrons: light and color.
