The aircraft carrier is the centerpiece of the United States Navy because of its ability to transport aircraft all over the world. The main component of these ships is their ability to launch and land jets in such a small space. But with so much chaos in such a small

When people kneel down to scrub the stains out of their bathtubs or struggle to remove the coffee grounds from their kitchen counters, they are probably not thinking about the complicated chemical reactions that are happening just beneath their hands. The cleaning supplies that we all use, from simple soaps

In a sport where a hundredth of a second can make all the difference, swimmers are constantly looking for ways to increase the efficiency of their stroke and improve their times. However, the physical force of drag remains a swimmer’s ultimate obstacle. There are multiple forms of drag – friction,

Billions of dollars are spent by consumers on hair care products every year, mostly on shampoo. Consumers are bombarded every day by advertising that promises stronger, shinier, healthier hair. Actually, differentiating additives, such as vitamins, account for small percentages of shampoo ingredients. The consumer may be shocked to hear that

While architecture based on tension has been used since ancient times, almost every permanent structure in the world, until about 50 years ago, was based on compression loading. Beginning in the 1950’s, there was a renewed interest in tension structures led by the German architect Frei Otto. As a result

Almost every major metropolis around the globe has a mass transit system. When executed properly, these can be the most economically and physically efficient means of moving large populations through a city. Unfortunately, only a few of these systems in the United States have been designed or operated well enough

In the post-September 11 era, engineers have developed new technologies to meet growing safety and security concerns at the world’s airports. The drawbacks of existing security measures – especially physical pat downs – have provided a foundation for “backscatter” X-ray technology. Information offered by the Transportation Security Administration and American

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
