The Effects of Acid Rain on the Visible Light Absorption of Stained Glass

Abstract: The effect of acid rain on stained glass windows is felt by many churches and other historic buildings worldwide, especially in Europe. As a result, the relationship between the traditionally dark interiors of these European churches and the acid rain that corrodes the stained glass was studied. Specifically, the effects of specific pHs of acid rain on the visible light absorption of stained glass over time were examined. In order to study this topic, […]

An Analysis of Spatial Changes Due to Special Relativity

Abstract: This thought experiment addresses loss of volume that occurs when a three-dimensional object is contracted due to relativistic processes. Specifically we investigate the dependence of contraction due to orientation relative to direction of motion. Length contraction states that relative constant velocity will lead to a shortened distance in the direction of motion, when viewed from a separate inertial reference frame. When applied to two dimensional shapes, this results in a reduced area. The problem […]

The Charge for the Future

Man’s eternal struggle to harness energy could take a step forward in the next decade through the use of tiny charged particles of matter: ions. Ions, which are composed of atoms or molecules that have lost or gained electrons, prove to be a promising source of energy in multiple fields of chemical engineering and material science. The secret to harnessing the power stored in ionic charges is to separate ions so electrons can flow freely, […]

Saturn's Aurora

The many wonders of Earth are but a fraction of the grandeur of our solar system, yet many of Earth's marvels are not unique to the blue planet.  One of Earth's more beautiful natural phenomena, an interaction between charged particles in the atmosphere and Earth's magnetic field known as the aurora, has also been observed at the poles of the gas giant Saturn.  The National Aeronautics and Space Administration's (NASA) space probe Cassini, which has […]

The technology behind the Arena X-Glide

Recently, the new Arena Powerskin X-Glide® was named one of the top 50 inventions of 2009.  This swimsuit utilizes various forms of technology to give the swimmer as many advantages as possible. Unlike other racing suits, it uses a full polyurethane coating, giving it the advantage of reduced friction. This coating also traps air, increasing the buoyancy of the swimmer and reducing drag. Underneath this coating, there are two layers – one layer of titanium […]
