Radios are incredible, aren’t they?
Think about how radios work for a minute. Vibrating electrons create radio waves that race through the air at the speed of light, crashing into receiving antennas where they are fine-tuned for our listening pleasure.
Most people already know radios work by decoding radio waves plucked right out of the air, but did you know our brains produce similar waves?
Brain waves are the radio waves inside our heads. Both are forms of electromagnetic radiation, albeit with a few notable differences.
So what if you could “tune in” to the brain waves of another person? What would you find? Is picking up on low-frequency brain waves even possible?
The researchers at the MIT School of Engineering posed this question, and it’s the topic of this Friday’s science break.
