Fresh research promises to enable engineers to design products that are smaller and much smarter. A team at the University of Maryland has created the world's tiniest transistor. Trillions of such transistors could fit on one computer chip--100 times more than is possible with current technology. Using a principle called tunneling physics, the researchers first produced a 25-nm transistor and then one as small as 10 nm. At that size, it would take 100,000 transistors to span the width of a single human hair. The advance, supported by the National Security Agency and the Naval Research Laboratory, could lead to smaller, more complex, and more efficient integrated circuits. "Whether or not this technology is adopted wide-scale by industry will come down to practical issues," says team leader Chia-Hung Yang, a professor of electrical engineering at the university.
The promise of the Internet of Things (IoT) is that devices, gadgets, and appliances we use every day will be able to communicate with one another. This potential is not limited to household items or smartphones, but also things we find in our yard and garden, as evidenced by a recent challenge from the element14 design community.
If you didn't realize that PowerPoint presentations are inherently hilarious, you have to see Don McMillan take one apart. McMillan -- aka the Technically Funny Comic -- worked for 10 years as an engineer before he switched to stand-up comedy.
The first Tacoma Narrows Bridge was a Washington State suspension bridge that opened in 1940 and spanned the Tacoma Narrows strait of Puget Sound between Tacoma and the Kitsap Peninsula. It opened to traffic on July 1, 1940, and dramatically collapsed into Puget Sound on November 7, just four months after it opened.
