The world of computing is a constantly evolving model of technological innovation, financial gain and ruin, and philosophical ideals. The open source revolution has placed these three branches of the industry in the spotlight, shaking the traditional foundations of the technology market. In a world of secrecy, and even deception,

The daily life of an average American is depending more and more on the Internet. Information and entertainment sites abound, but many of the billions of web pages are yet unknown. Search engines are the pipeline through which users can quickly find the content they desire. The history of online

In order to bring high-speed internet to areas where developing a traditional broadband infrastructure would be cost prohibitive, engineers have recently begun working on developing techniques for delivering broadband internet signals over the existing power supply grid. By using an entirely different frequency range, power lines can carry traditional AC

Mobile phones allow users to place calls, send text messages, and receive updates from the internet. Information from a mobile phone is sent and received by way of electromagnetic waves. All information is encoded prior to transmission, decoded upon arrival, and must be sent so that many users can share

Tele-Immersion (TI) involves the construction of a three dimensional (3D), realistic holographic environment where two or more physically separated users can communicate with each other in real-time. Existing video conferencing applications lack this dimensionality and realism. Tele-Immersion is an engineering solution to this deficiency and is made possible by combining

A collection of recently developed audio technologies allows for the creation of thin, directional sound beams. With this type of equipment, focused streams of sound can be pointed exactly where the user wants them. Directional sound technology will likely see widespread adoption in the near future as engineers continue developing

The launch of Sputnik in 1957 by the USSR marked the beginning of the satellite era. The next half-century saw new research and development that changed satellites into the useful tool of contemporary society. Modern satellites can help locate people all over the world, aid in scientific research, and perform

Radio Frequency Identification Devices (RFID) are widely being hailed as the up-and-coming successor to barcodes. The superiority of RFID lies in its faster speed, rewriting capabilities, and the fact that the device need not be visible to be read. However, until the cost of RFID is lowered, barcodes will remain

Beer has existed for thousands of years. During its long history its popularity has changed considerably in response to technological advancements and social pressures. Although beer was created before the science behind it was understood, the process of making beer can be thought of as a series of chemical engineering

The digital image sensor is a technology used to record electronic images. The most commonly recognized application of the digital image sensor is the digital camera. In digital cameras, the image sensor is used in conjunction with a color separation device and signal processing circuitry to record images. The two

Long before the age of computers, light bulbs, automobiles, or locomotives, a revolutionary feat in engineering transformed society. This technology almost singly separates developed countries from their developing counterparts, and many Americans take it for granted. Rarely do we ever think about it when we use it, and when we

The natural environment is very easily polluted by the toxic compounds contained in oil. In the past, methods for restoring contaminated areas have been expensive but largely inadequate. A recently developed decontamination process called phytoremediation uses plants along with the bacteria that live in their roots to break down the

Immersion is the process by which a media element entices a person to suspend their disbelief and accept what they are viewing on a screen or page as actual reality. Through non-linear dramatic elements and interaction between the player and the computer, a video game achieves a level of reality

The Frisbee, generally held to be a simple toy for children, was invented and refined in the late nineteenth century. Although it has grown in popularity since then, its general design, and thus the technique for its use, have remained fairly constant. The flight of a Frisbee is allowed and

Photochemical smog, created by any gasoline-powered vehicle on the road, is a major concern in Los Angeles today. Buses, despite being implemented to reduce this pollution by lessening the number of cars on the streets and freeways, are smoke-spewing machines that pose a risk to environmental and public health. They

The brain is our body’s information processing center. It controls everything that we do, making us intelligent, conscious, and alive. The brain is made up of over 100 billion neurons. The neuron, or nerve cell, is a type of cell responsible for the body’s gathering, processing, and transmission of information.

The history of the harp goes back thousands of years. The harp is regarded as the world’s oldest string instrument. It influenced the evolution of the piano, guitar, and violin. Engineering is the application of science to the art of problem solving; the harp has encompassed the ideals of engineering.

Bamboo is emerging as an alternative resource to other types of wood. In the past, people intuitively used it as a basic material for making many different household objects and small structures. However, ongoing research and engineering efforts are enabling us to realize bamboo’s true value as a renewable, versatile

It is not uncommon to see distinctions drawn between civil and environmental engineering projects. Preconceptions are regularly formed over what truly constitutes an environmentally friendly task, and these preconceptions rarely include the work of civil engineers. However, many engineering wonders exist primarily due to the interaction between these two disciplines.

Malaria continues to plague peoples worldwide, transmitted by a viral parasite carried by mosquitoes. Vaccines and pesticides have combated the disease in the past, but the disease adapts and becomes resistant to drugs, and pesticides such as DDT hurt the environment while killing mosquitoes. Geneticists have developed a new solution

The advancement of technology and the preservation of the environment do not have to be opposing goals. When taken together, these objectives provide the basis for sustainable technologies that reduce resource consumption and pollution. Through the use of these technologies and a little creative planning, a building can be constructed

Bicycles have been around for many years and are constantly being researched and improved. Many disciplines of science and engineering are necessary in making the bicycle what it is today and will be in the future. Since the appearance of the first bicycle in the late 1700s, this machine has
