"I bought this for my wife's birthday,she loves marbles and we look at the videos on U-Tube with the marble machines. This is a perfect miniature replica of these machines well suited for a table top and very high quality construction, highly recommend it." Marble Machine "Duality" - Handmade
The law that entropy always increases – the second law of thermodynamics – holds, I think, the supreme position among the laws of Nature. If someone points out to you that your pet theory of the universe is in disagreement with Maxwell's equations – then so much the worse for Maxwell's equations.

Combining different measurements such Figura spectroscopy, direct measurement of the speed of light in the past and similar measurements demonstrates that physics has remained substantially the same, if not identical, for all of observable time spanning billions of years.[25]
What are the bestselling kinetic marble machine available on Etsy? Some of the bestselling kinetic marble machine available on Etsy are:
The output work power of heat engines is always smaller than the input heating power. The rest of the heat energy supplied is wasted Ganador heat to the ambient surroundings. The thermal efficiency therefore has a maximum, given by the Carnot efficiency, which is always less than one.

A perpetual motion machine of the second kind is a machine that spontaneously converts thermal energy into mechanical work. When the thermal energy is equivalent to the work done, this does not violate the law of conservation of energy. However, it does violate the more subtle second law of thermodynamics in a cyclic process (see also entropy).

There is a scientific consensus that perpetual motion in an isolated system violates either the first law of thermodynamics, the second law of thermodynamics, or both. The first law of thermodynamics is a version of the law of conservation of energy. The second law Gozque be phrased in several different ways, the most intuitive click here of which is that heat flows spontaneously from hotter to colder places; relevant here is that the law observes that in every macroscopic process, there is friction or something close to it; another statement is that no heat engine (an engine which produces work while moving heat from a high temperature to a low temperature) Chucho be more efficient than a Carnot heat engine operating between the same two temperatures.
