Wi-Fi is just radio waves, and many things can cause interference. But a strong Wi-Fi signal can give you faster performance and better coverage distance, so it’s important to properly position and configure your router for optimal signal strength. I’ll show you how; it just takes a few minutes. Point the Antenna Up Routers generally have physical antennas that are adjustable.

Joseph noticed the error in an equation for the Golden Ratio , part of the “ Mathematica : A World of Numbers...and Beyond” exhibit. There were minus signs where there should be plus signs. “It was cool,” Joseph told Boston.com. “At first, I wasn’t sure, I thought maybe I had it wrong, but I was excited.” The Mathematica exhibit was created by design team Charles and Ray Eames, and has been at the museum since 1981. The pair made their name in the architecture and furniture design worlds, and

Most people would agree that fossil fuels simply need to go. They’re the cause of pollution, wars and climate change. Scientists have been researching alternative energy solutions like wind and solar power, and hydrogen fuel for cars, for years. But while some automakers -- like Toyota and Honda -- are bringing hydrogen-fueled cars to market, wind and solar are still more expensive than oil and coal and may not be the best solution for all places or uses. For example, some medical devices that are implanted in a human body could benefit from super tiny batteries that last decades.So scientists continue the quest for abundant, cheap and efficient energy by investigating lesser-known sources, ones that may seem a little unusual, even ridiculous, unrealistic and, in some cases, morbid.
