Agricultural engineers explain their work and how they use biology and engineering to make farms energy efficient and the food supply safe and plentiful. They describe what drew them to this profession and also discuss their education and career paths.
A main goal of the 2013 Colombian Engineering Meeting was to gather teachers, students, researchers, professional associations, and the private sector to discuss issues related to engineering. This important event showed technological and theoretical advances of the wide world of engineering.
Joel and the Curiosity Quest crew visit Big Toys Factory to learn how playground equipment is made. The toys from this factory are made from recycled materials. Part of the Curiosity Quest Series.
Shawn and his friends go to the factory to see a prototype for a new train. While at the factory, they help build trains and have to rescue Rusty Robot after an accident occurs. Part of the "Shawn and Team" series.
Today's optoelectronic engineers are developing extremely thin glass that is both durable and scratch-resistant. Telecommunications systems require speed and accuracy, and glass is proving to be important in developing semiconductors, optical fibers, and multiplexing. Precisely engineered glass is also used in terrestrial and extra-terrestrial telescopes.
Engineers are motivated to improve our quality of life, and they typically develop new products to achieve this goal. They use several steps in developing new products: design phase, testing phase, and production and maintenance phase. During the design phase, engineers specify the functional requirements of the product. They also produce a prototype to evaluate its overall effectiveness. They also consider cost, reliability, and safety. During the last two phases, engineers determine if any failures of the components are likely and where they occur. In these processes, engineers use computers to create designs, analyze functionality, and simulate how a machine, structure, or system operates.
Fly into this high-tech career and learn about satellites, airplanes, and maybe even flying cars of the future. Aerospace engineering is the primary field of engineering concerned with the development of aircraft and spacecraft. Part of the "I Can Be Anything I Want to Be A to Z" series.
Structural engineers at the University of California, Los Angeles are hoping to design earthquake-resistance buildings and communities. They are using data and computer modeling to design structures able to withstand major earthquake events. These models are meant to guide safety inspections following earthquakes and help engineers locate “hotspots” more quickly. Part of the “Science Nation” series.
Architect Maria Paz Gutierrez is a woman on a mission to end water scarcity. Together with environmental engineer Slav Hermanowicz and bioengineer Luke Lee, she is hoping to take the recycling of wastewater from sinks, baths, and laundry to a completely new level. With support from the National Science Foundation (NSF), the multidisciplinary team is engineering solar panel technology that makes greywater reusable while creating thermal energy in the process. Part of the "Science Nation" series.
There’s a new renewable energy player in town, and it’s about to make waves in the industry. Despite its massive potential as a source for renewable energy, the ocean is unlikely to contribute meaningfully to electricity supplies without dramatic, innovation-driven reductions in the cost of energy conversion. That’s where engineers Balky Nair, Rahul Shendure, and Tim Mundon come in with their company, Oscilla Power. With support from the National Science Foundation, they’re developing a utility-scale wave energy harvester called the Triton. This technology shows promise as a means for delivering utility-scale electric power to the grid at a price that is competitive with conventional fossil or renewable technologies. Part of the National Science Foundation Series “Science Nation.”
NASA’s "Juno" spacecraft traveled 1.7 billion miles to reach its destination: the planet Jupiter. Before "Juno’s" journey, NASA engineers had to develop a spacecraft capable of surviving the trip. They researched and created "Juno," a solar-powered spacecraft. Part of the “Crazy Engineering” series.
Ion propulsion might sound like science fiction, but engineers at NASA are using it to drive NASA’s "Dawn" spacecraft through the solar system. Learn how ion propulsion works and why it is the reason "Dawn" will be the first spacecraft ever to orbit two solar system bodies beyond Earth. Part of the “Crazy Engineering” series.
See how geckos inspired new NASA technology that makes things stick to each other in space. Potential future applications might be to grab and service satellites or to salvage space garbage. Part of the “Crazy Engineering” series.
The engineers at NASA are studying cellphones and computers as a means to create a mini-satellite called a CubeSat. CubeSats are small but highly capable of performing a variety of space missions. Part of the “Crazy Engineering” series.
NASA engineers are looking for new ways to explore Mars. They are working with a small helicopter that could help scout trails for future explorations into space. Part of the “Crazy Engineering” series.
Humans have always been intrigued by the idea of flight. Experiments with Hot Air Balloons led to a pig and duck being the first air travel passengers. From there, the Wright Brothers created the first airplane, and aviation was off to the races. From the jet engine and military aircraft to passenger planes, worldwide travel is now a matter of hours rather than days or weeks.
In 1990, when the first images from NASA's Hubble Space Telescope were too blurry to use, JPL scientists and engineers went to work to devise a fix. They created a camera with corrective vision to bring Hubble images into sharp focus. Part of the “Crazy Engineering” series.
The engineers at NASA are studying two new technologies to help image distant Earth-like planets. Coronagraphs are tiny instruments fitted inside telescopes to block light and help scientists study clues as to whether life is present on a planet. Starshades also block light and produce clearer photographs of distant planets. Both of these technologies are used with telescopes and provide scientists with enhanced photographs of space. Part of the “Crazy Engineering” series.
To traverse the surface of the Moon or Mars, a vehicle must be able to think for itself. At NASA's Jet Propulsion Laboratory's testing ground, a team of scientists demonstrates the rover that will soon wander over the Martian landscape.
