Scientists do not know exactly what the nature of the transition between the liquid and solid phases and glassy, ​​and what physical processes lead to the basic properties of the glass.

2. Why did the bike falls on its side? The design of the bike is quite simple, and it seems that has long understood how and why the two-wheeled vehicle maintains excellent stability. But not steer automatically when your side centrifugal force or the gyroscopic moment of the rotating wheel in this no blame has been tested and proven.
