Engineering is the discipline of design and construction of mechanical devices, equipment, structures and public works systems. Topics include aircraft technologies, buildings, bridges, robotics and heavy machinery.
A soft-story building has a first floor that's more flexible than the ones above -- think apartments over a department store that's mostly open space. How does soft-story retrofitting keep such buildings from collapsing in a quake?
You might associate green architecture with plastic rain barrels or ugly solar panels, but green design has come a long way. Green architecture can be gorgeous, as we'll see in this article.
If you think regular old domes took the world of structural engineering by storm, you should meet their geodesic cousins. What is a geodesic dome, and who first came up with the idea of building triangle-covered spheres as practical structures?
Bridges span the gap and help us get from point A to B, but who knew they could float, too? Find out what the deal is with floating bridges in this article.
Jenga seems like such a simple game -- all you have to do is keep a tower of wooden blocks from toppling over. It may be simple, but it's anchored by several complex structural engineering concepts.
Playing with Lego blocks isn't just child's play. In fact, these blocks and products present a hands-on opportunity to learn the basics of structural engineering.
You may see most bridges as those things you cross on your way to somewhere else, but where would you be if one collapsed? We've figured out 10 reasons why the worst happens.
The World Trade Center employed several new approaches to skyscraper construction. From slurry walls to sky lobbies to "tube within a tube" design features, what made this project distinctive from an architectural engineering standpoint?
The materials used to build the World Trade Center's twin towers have been heavily scrutinized since the 9/11 terrorist attacks -- including the steel that formed the frames of the skyscrapers.
It's been compared Jerusalem's Wailing Wall. What purpose did the slurry wall serve the World Trade Center, and what is its significance now?
It took years to construct the 110-story World Trade Center towers and less than an hour to bring them down to rubble. What ultimately caused the towers to collapse on Sept. 11, 2001?
Steel is getting more expensive because the prices of iron and coal are rising. Are there alternatives to steel that can do the same job -- or better -- for less?
Full-size robotic mannequins give birth to robotic babies every day in medical training facilities. How do these mommy mimics prep students for the real deal?
Glass ionomer cement is a kind of cement used in restorative dentistry. Learn what glass ionomer cement is in this article.
Dozens of different types of architectural home styles from Federal to Mediterranean exist in the United States. Learn about the different types of architectural home styles in this article.
Wind tunnels are the unsung heroes of aerodynamics. Thanks to these breezy devices, we have safer planes, cars and space vehicles.They even provide some extreme fun for the adrenaline junkies among us. What's the deal with wind tunnels? Find out in this article.
Sports injury taping has undergone a quiet revolution over the last 30 years. How can a pattern of tape stuck to your body help you heal from (or prevent) an injury?
Fractals produce fascinating and intricate designs. Browse through this gallery featuring pictures of a variety of fractals like Mandelbrot and Julia sets and find out why nature is loaded with fractals.
Dyneema is trademarked as the world's strongest fiber. Find out how this high-strength synthetic is capable of protecting an individual (or an entire vehicle) from IEDs or even shots fired from an AK47.
You probably know that high pitched or high frequency sounds can break materials apart. But did you know that high frequency sounds can be used to bond materials together?
Robots continue to work their way into every aspect of our lives, but these advancements aren't self-sustaining. The fields of robotics, engineering and science depend on a steady pipeline of young minds. And that's where FIRST comes in.
Pisa without its precariously tilted landmark is like San Francisco without the Golden Gate or London without Buckingham Palace. Will the peculiarly enduring tower ever vanish from the Italian skyline?
When it came to building or improving things, the ancient Romans really knew their stuff. Which cool engineering tricks did they pass along to us?
Break things down to the original Latin and the term "manufacturing" is literally a matter of using your hands to make things. These days, those hands often aren't human. So how are robots remaking our world?
An MRI scan is the best way to see inside the human body without cutting it open, but that may be little comfort to you when you're getting ready for the exam. Lying perfectly still on a tiny slab in a narrow hole, you might wonder what's happening to your body.
