Long before GPS satellites and other high-tech navigational aids, the compass gave humans an easy and inexpensive way to orient themselves. But what makes a compass work the way it does? And why is it useful for detecting small magnetic fields, as we saw in How Electromagnets Work? In this...
First conceptualized by Russian physicist Victor Veselago in 1967, these tiny, artificial structures are smaller than the wavelength of light (they have to be to divert them) and exhibit negative electromagnetic properties that affect how an object interacts with electromagnetic fields. Refractivity and...
How do humans use electromagnetic waves? How do electromagnetic waves travel without a medium? How are the electromagnetic force and the weak nuclear force alike? How are electromagnetic waves produced by accelerating charges? What machine uses electromagnetic force?
What Electrical Engineers Do and Why It Matters Because electricity is ordinarily invisible to the naked eye, someone who intends to work as an electrical engineer should be curious about mysterious forces that significantly affect the universe but aren't obvious to a layperson. ...
In today’s technology-filled world, we are surrounded by electromagnetic fields (EMFs), invisible energy fields that affect us up to 24 hours a day. With the growth of wireless technologies, there are more questions every day, with the main one being: Are they safe?

So if this is true, then why do health professionals advise to avoid close and prolonged exposure to even weak electromagnetic fields? Don't sit too close to the television. Don't stand directly in front of the microwave if you're pregnant. Don't sleep under a running electric blanket. ...
not impossible, but that doesn’t mean we should do nothing. This article you will inform yourself about what scientists say wireless electromagnetic radiation is doing to us. The PETITION LINK is there . . . NIMFY — Not In My Front Yard. "How can we tell how we feel when we're ...
Another good method is to do some yogic visualisations such as the following: 1. Slightly close your eyes, stare at the tip of your nose and slowly raise your gaze to the bridge of your nose. 2. Sit up with your back straight or lie down completely flat on your back. Keep your palm...
power microwave weapon located at some distance from the targets. Power decreases dramatically with distance through theinverse square law, which means one of these devices could produce a power level at the target that would be too low to affect electronics but that could induce the...
