Most drivers do not know that the most important parts of any car are its tires. The tires have an enormous influence on the safety and performance of an automobile. While tires may appear to be simple devices, developing them is an extremely complex process. It is based on subtle

With Americans working longer hours, there is less time to create a meal from scratch. The invention of frozen food has allowed us to simply microwave a meal in a few minutes, providing us with more time to spend on our hobbies and with our loved ones. Although some people

Unmanned Aerial Vehicles (UAVs) are a fusion of many engineering disciplines. They are the premier platform for advanced communication, surveillance, and propulsion technologies. While they have recently garnered most of their press on the battlefield, an emerging commercial sector is attempting to make them part of everyday life. Introduction Anyone

The Global Positioning System (GPS) is rapidly becoming an integral part of our everyday lives. The system, created by the United States Department of Defense in 1973, has gone through many changes since its introduction to the public in 1995. GPS uses the concept of trilateration to provide your location,

Mars, a planet once warm enough to support water, is now a cold and dry wasteland unable to sustain human life. Many scientists believe that through the introduction of carbon dioxide to the atmosphere, the Martian environment can be terraformed into a planet like Earth. Possible methods for introducing carbon

Advertisements for some new types of televisions claim that their superb picture quality is due to “the mirrors.” These mirrors are on the order of microns wide, and millions of them reside in the back of DLP televisions. This way of projecting the light source is a cutting-edge method (over

Virtual technology has brought a whole new perspective to watching football from your couch. The implementation of first-down lines in television broadcasts of America’s homegrown sport has provided fans with a viewing experience that integrates cutting edge technology into the fast-paced world of athletics. This single yellow line may appear

This article explores the future of the Panama Canal as part of the global transportation system. Beginning with a brief overview of how vessels pass through the canal this article outlines the canal’s importance to the global economy. It identifies three problems the canal is faced with regarding efficient traffic

Doping is the use of performance enhancing drugs or methods by athletes to gain a competitive advantage. Blood oxygenation enhancement is a type of doping that artificially increases an individual’s hemoglobin concentration above normally occurring levels. Two common methods of blood doping are blood transfusion, or the transfer of blood

As museum-goers, we often assume that artwork looks just as the artist intended it to look. This is generally not the case, as the passage of time necessarily degrades art, often in the form of dirt or cracks. The use of two technologies, laser ablation and bacteria, is helping to

With the recent boom in digital technology, science has opened the doors to historical secrets. For years, engineering has paved the path to knowledge. Now, it has come to the aid of aesthetes, uncovering the mysteries hidden for us by history’s master artists. 3D scanning provides art historians with virtual

Engineers at Numotech Inc. and Sandia National Laboratories have designed a device that can reduce the healing period for many different types of wounds including plastic surgery incisions, burns, and necrotizing fasciitis. The most striking feature of the product is its simplicity, which hides the enormous amount of engineering that

Beneath even the biggest soccer stars is a pair of shoes designed and tested by engineers to push the limits of the game. The soccer boot (the traditional name for a soccer shoe) has evolved a great deal in form and function, particularly in the past few decades. To keep

Base isolation has become a major feature of structural design in the past few decades. While a relatively simple concept, base isolation has a long and involved history of engineering influence and will take many more years to refine. Base isolators act on well-understood physical principles such as energy, oscillation,

Electric or ion propulsion is the newest propulsion system that NASA has put into successful operation. The Deep Space 1 mission used the ion engine as its primary propulsion system and tested its capabilities for the 21st century. Its advantages over conventional propulsion include lower fuel weight, much higher fuel

Engineers have created a tool known as the sampler that allows the user to play a prerecorded sound at any time. The sound can also be pitched, stretched, cut up, rearranged, looped, layered and reversed. Through the sampler, engineers have profoundly influenced music and the way that it is produced

The global fresh water supply has become a major concern as most third world nations, and even some developed countries, face the disconcerting reality that drinkable water is running out. To solve this newly realized crisis, engineers are offering the world new, innovative techniques for water purification. Nanotechnology, technological development

Biodiesel is a renewable source of energy that could potentially reduce the world’s dependence on coal and crude oil. It is a byproduct of refined vegetable and soybean oils, and it contains almost the same amount of energy per gallon as traditional diesel while having cleaner emissions when consumed. Biodiesel

The Botox injection is by far the most popular cosmetic procedure performed today. Botox, or Botulinum toxin A, works by blocking the release of a key chemical, acetylcholine, preventing the transmittal of signals from nerve cells to muscles. This unique effect makes it useful clinically in treating neurological and neuromuscular

The Walt Disney Concert Hall, designed by architect Frank Gehry, makes extensive use of computer technology. Without the use of CATIA (Computer-Aided Three-Dimensional Interactive Application), construction of the concert hall would have been impossible. After a physical model is built, the model is scanned by a laser device that transmits

Two retinal diseases, Age- Related Macular Degeneration (AMD) and Retinitis Pigmentosa (RP), are the leading causes of blindness in individuals over the age of 65. Despite various treatments such as gene therapy and retinal tissue transplant, physicians have thus far been unable to combat the blinding effects of these diseases.

At its essence, paintball is about marking other players with gelatin capsules filled with colored dye shot from a gun powered by compressed gas. While the fundamentals of the game have not changed since its inception, the technologies behind many of its principles have advanced. Fuelling this change is the

The skin is a complex organ with many layers. Its structure is designed to minimize moisture loss from the body while preventing foreign materials from entering. To accomplish these functions, the skin must have a protective covering of lipids, or oil-soluble molecules. Exposure to everyday conditions can strip the skin
