None of these products break new ground for Dyson. These are all categories the company has already dabbled in, but the products are even more refined now. First up: $600 Dyson Lightcycle. Yes, that's the actual name and it has nothing to do with Tron. Instead, the "cycle" in this refers to day and night. This connected lamp takes the basic metal arm design of Dyson's CSYS task light and sticks a microprocessor into it.It receives real time data tracking the current position of the sun, and adjusts the light level accordingly. It'll gradually get brighter as the day goes along, with its greatest intensity at noon. As it transitions into evening the light will get warmer, that way you avoid pesky blue light that might keep you from sleeping properly.You're not entirely beholden to that giant ball of fire in the sky, though. The top of the lamp has touch controls that let you adjust the light levels and, if you really want to fine tune it, you can also customize the light's brightness … [Read more...] about Dyson’s latest handheld vacuum works smarter, not harder

There are so many real-world physics problems involved in running. Lots of physicists have been inspired, for instance, by the crazy-fast speeds of Usain Bolt. Just take a look at this paper, "On the performance of Usain Bolt in the 100 m sprint" (European Journal of Physics), in which the authors examine the motion of Usain in one of his sprints. But what if you want to look at more ... unrealistic running? Or model running in situations you shouldn't test in real life—like running at the pool? In order to explore these situations, you'll need a physics model for running. Remember that science is all about building models, right? Let's say I want to build a model that shows the following real-world aspects of running: A runner hits the ground and then is off the ground during part of the motion (both feet off the ground). A runner accelerates but reaches some maximum speed. It's fairly easy to fit a mathematical equation to a runner's motion. But what if you want to go a … [Read more...] about How Is a Runner Like a Bouncing Ball?
Chipmakers face a multitude of challenges in the fab at 10nm/7nm and beyond, but one technology that is typically under the radar is becoming especially difficult—metrology. Metrology, the art of measuring and characterizing structures, is used to pinpoint problems in devices and processes. It helps to ensure yields in both the lab and fab. At 28nm and above, metrology is a straightforward process, as the transistor is planar or two-dimensional with larger feature sizes. And with relative ease, chipmakers use a handful of metrology systems to measure structures. But metrology has become more complex and expensive at each successive node. The challenges escalated when planar transistors ran out of steam, prompting chipmakers to migrate to finFETs. Intel introduced finFETs at 22nm, while foundries moved to finFETs at 16nm/14nm. With this 3D transistor structure the control of the current is accomplished by implementing a gate on each of the three sides of a fin. While this reduces … [Read more...] about FinFET Metrology Challenges Grow
In March, Ajit Pai, the 45-year-old chair of the Federal Communications Commission, took to the internet—a community he joyfully inhabits and grudgingly regulates—to pay tribute to his favorite movie. “It’s not just, like, my opinion, man: 20 years ago today, #TheBigLebowski—the greatest film in the history of cinema—was released,” Pai wrote on Twitter. “Decades on, the Dude still abides and the movie really ties us all together.” And sure enough, the response to Pai’s cheerful tweet was united. You’re out of your element Ajit. —@JohnsNotHere Yes, Ajit. Stop trying to mingle with humans. —@Douche_McGraw I hope you enjoy watching that movie alone since you have zero friends —@aseriousmang No one likes you dork —@chessrockwell_ The insults, hundreds upon hundreds of them, accumulated in his replies. Some took the form of incredulous Jeff Bridges GIFs, others mimicked famous lines of Lebowski … [Read more...] about This Is Ajit Pai, Nemesis of Net Neutrality
