"When you walk, you're really in what's called a controlled fall. You off-balance yourself, putting one foot in front of the other and falling onto them over and over again. In the same way, when you use a Segway, there's a gyroscope that acts like your inner ear, a computer that acts like your brain, motors that act like your muscles, wheels that act like your feet. Suddenly, you feel like you have on a pair of magic sneakers, and instead of falling forward, you go sailing across the room."
- Dean Kamen
"You're walking. And you don't always realize it,
but you're always falling.
With each step you fall forward slightly.
And then catch yourself from falling.
Over and over, you're falling.
And then catching yourself from falling.
And this is how you can be walking and falling
at the same time."
- Laurie Anderson
