They really are an underappreciated invention — it took a lot of work!
Gifts that will keep the gears of love well oiled.
To most people, the sky is the limit. To those who love aviation, the sky is home.
The resolution density of today’s displays is nearing its limits but a novel technology could change all that.
This jaw dropper is the Wärtsilä RT-flex96C, the world’s largest and most powerful diesel engine in the world today.
Outstanding control is what distinguishes a toy rocket from a real one.
Over the past few years there has been much talk about the importance of scientific development in Africa. With the international development agenda, including the new Sustainable Development Goals, increasingly recognising the critical importance of science, technology and innovation in human, social, and economic development, the battle for advanced science is beginning to be won. However, for Africa, grand questions
Every year, the Land Art Generator Initiative (LAGI) in Copenhagen welcomes renowned designers and engineers to submit designs that integrates renewable energy in harmony with citizens, nature, and the urban environment. This year’s winning entry is a fantastic solar power array that takes the form of a hourglass, unveiled by Argentina-based designer Santiago Muros Cortés. The project, if constructed, would power 1,000 Danish
Depending on where you live, bike stealing can be a distant threat or a constant worry, but in most parts of the world, people would rather be safe than sorry, tying their bikes to trees or fences or whatever they could find. But that may very well change in the near future: three engineers from Chile have developed a bike
The humongous grey whale and the skipjack tuna, though of contradicting sizes, both employ similar propelling mechanisms through water. Pound per pound, however, which of the two animals is most energy efficient? Engineers at Northwestern University have developed a new metric for analyzing such problems and found that the two marine animals are almost just as energy efficient despite the great
We haven’t actually shied away from praising the marvels of 3D printing. We’ve told you all about printing fossils, medical implants, even skin, bones, bacteria or organs! Of course, these are some eccentric uses since, after all, 3-D printing was designed for manufacturing in mind. It’s easy imagine a not so distant future where most goods are 3-D printed, even by
Healthcare has been changing at a rapid pace the last few years. Now, with the passage of the Affordable Care Act (ACA), there are even bigger changes in the near future. As the face of healthcare changes, so must the facilities used by healthcare professionals. In an attempt to keep costs down hospitals will become places for the sickest of
This “How to” may not be that relevant in modern times, but in the XIV and XV century, I could think of a few civilizations that would have loved to learn how Chinese engineers moved huge volumes of rock from quarries tens of miles away. Such blocks of stone, weighing at least 100 tonnes, were used to build the splendid
Most people may not be aware that for an engine to work at its peak performance, the lubricants used to keep the parts aligned and wet need to be free of any contaminants. There have been studies pointing out that 75% of all fluid engine or mechanical failures can be linked to issues involving contamination. This is what filters are
The Peruvian capital of Lima, along with its outskirts, is plagued by a vicious drought, which coupled with pollution and unsanitary water extraction methods, has made the water there stagnant, dirty and dangerous. Doing what they know best – fix problems – engineers at Peru’s University for Engineering and Technology have devised an resourceful system that sucks up the moisture out
As I was telling you in a previous article, researchers from NASA have created a high-res gravity map for the Moon, using two twin man-made satellites – Ebb and Flow. The satellites have done their mission well, shedding light on many of the Moon’s features, but NASA isn’t planning a safe return for them: they are currently being prepared for
There were 5.4 million automobile crashes on U.S. roads in 2010, killing 33 000 people and injuring more than 2.2 million, according to survey released by the U.S. National Highway Traffic Safety Administration. The death toll around the world is much higher. While cars have been designed to be a lot safer by making them more crash resistant in the past decades,
Since they were first invented in 1931, aerogels have become widely used in the industry, mostly for insulation purposes, thanks to their low thermal conductivity and light weight. Traditional silica aerogels, however, are brittle and obtuse, typically unsuited for applications where flexing of the material would occur. A novel class of polymer aerogels seeks to fix most of these inconveniences, after scientists
According to biblical account, the Tower of Babel was an enormous tower whose top was intended to reach for the very heavens. Amused by this ploy, God said “Come, let us go down and confound their speech.” With their tongues twisting words in different languages, the people there couldn’t coordinate their efforts any longer. Man never gave up on tall constructions,
Scientist at MIT and Harvard University teamed up to figure out what would be the simplest 3-D structure capable of collapsing and morphing due to instability. Their inspiration came after the scientists came across a popular toy, spherical in shape and fitted with movable parts and hinges, which allows it to easily dimple in size reversibly. Based on this toy, the
