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.

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?

Once upon a time, food was used for one thing: eating. Today, it has a much more complicated role. And one of those roles might be serving as an upstart in the world of plastics.

Versatile and efficient, electroluminescent (EL) wire is widely used by artists to illuminate clothing, bicycle spokes, turntables and even cars. But how does this cool product work with so little power and without a visible energy source?

This not-so-new material looks like a hologram and could play a valuable role in the future of insulation, electronics, oil spill cleanup and green energy. So why don't aerogels have the A-list name recognition they deserve?

The American Marketing Association created the Edison Awards to honor inventors and their innovations. With many great ideas to choose from, what are some of the nominees for 2010?

Nanotechnology is one of the hot buzzwords of the 21st century. You know that it has to do with things that are very small, but just what are the implications of technology on the molecular scale, anyway?

When most people talk about nanotechnology, they're referring to tiny machines built by humans. Could any molecules found in nature qualify as natural nanotechnology?

If people could create nanomachines, they might be able to help fight diseases on the molecular level. They might even be able to replicate themselves. But what happens if that process gets out of hand?

Science fiction prepared us for life with robots long before it became a reality. They've already changed the way goods are manufactured, but can they truly change the way human beings live?

Artificial intelligence has advanced very quickly. Some believe that it's possible that machines will eventually be able to improve themselves. But could machines ever truly achieve consciousness?

Engineers have gotten good at making very small things. We're already talking about building at the nanoscopic scale. Is it possible to build tiny machines that can move even tinier atoms?

Skyscrapers are fascinating engineering feats, but they can also be beautiful additions to city skylines. Travel to new heights with this skyscraper gallery.

It's common knowledge that Thomas Edison invented the incandescent light bulb and the phonograph, but did you know he also developed concrete furniture and a phone to communicate with the dead?

The Edison Awards annually honor the best new, cutting-edge products, companies and business executives -- all in the name of the record-setting inventor, Thomas Edison. What exactly does it take to earn an Edison Award?

Every now and then, a new product bursts onto the scene, causing a sensation among consumers and leaving an indelible mark on a given industry. These amazing innovations are contenders for an Edison Award.

Over the centuries, some of the most breathtaking buildings on Earth have been restored many times. Whether they were to make necessary repairs, update designs or adjust to changing needs, all these projects required big bucks.

Water towers can be found in just about every town and city in America. Have you ever wondered if they freeze in the winter?

Whether they’re adorable like ASIMO or creepy like the world's most lifelike androids, today's robots take on a range of shapes and sizes. But they're not all humanoid. This gallery also shows off a few that are inspired by the animal kingdom.

Bridges move cars, trains, bikes and people, among other things. These 10 may even move your soul with their engineering ingenuity and beauty. So which 10 make the cut?

For a process that simply bonds two pieces of metal, welding affects a lot of our world and some stuff that's out of this world, like the International Space Station. What's it like to man the torch?

This nonlethal weapon doesn't cause any lasting damage, but it may cause you to pray to the porcelains gods if an officer shines one in your eyes long enough to subdue you.
