Tesla said it. Einstein Agreed. Science proved it. It is a known fact that everything—including our own bodies—is made up of energy vibrating at different frequencies. That being said, can sound frequencies affect us? They sure can.
Smooth. Bulk metallic glass gears don't get brittle in extreme cold. That makes the material perfect for robotics operated in space or on icy planets. Here we see an example of a strain wave gear, also known as a harmonic drive. As the gear turns, the flexible ring inside it squeezes, becoming an oval shape.
