(9:00AM to 5:00PM)
- Great gift idea, decoration, and a cool collection for the science physics enthusiast.
- A simple spin of the top of the base sets the galaxy in motion.
- Requires 2 AA batteries - not included.
- Simple to assemble components, Silver rings continuously spin around a central sphere. This kinetic sculpture has several brightly colored metallic balls rotating like a Ferris wheel.
A Brief History
Perpetual motion continues indefinitely without any external source of energy. This is impossible to ever achieve The Perpetual Motion Machine, a hypothetical machine, that can work indefinitely without an energy source because of friction and other sources of energy loss, and the violation of the first or second law of thermodynamics.The idea of perpetual motion machine originated in India, around 1200 AD and the idea spread from India to the Islamic world, then spread to the west.
During the Renaissance, Leonardo da Vinci (1452-1519) made a similar device, he thinks that the right heavy ball is farther than the left side ball for the distances from the center of the gravity, under the action of unbalanced, the wheels will rotation along the direction of arrow, but the results is negative.
In the middle of the 19th century, a series of scientific workers to made tremendous contributions to recognize the function of heat transformation and transformation relationship of other forms of material movement, the great law of conservation and transformation of energy was found after it, and the law of conservation of energy is established. As the understanding of perpetual motion, some countries limit the invention of perpetual motion.
