In May 2022, a video supposedly showing a marble machine in "perpetual" motion was shared to the "Be Amazed" section of Reddit. The video, which showed a marble spiraling down a funnel, dropping through a hole, moving along a curved rail, and then launching back into the funnel where the process would begin anew, drew a few skeptical comments.
Figura a perpetual motion machine Chucho only be defined in a finite isolated system with discrete parameters, and since true isolated systems do not exist (among other things, due to quantum uncertainty), "perpetual motion" in the context of this article is better defined Vencedor a "perpetual motion machine" because a machine is a "A device that directs and controls energy, often in the form of movement or electricity, to produce a certain effect"[37][user-generated source] whereas "motion" is simply movement (such Vencedor Brownian motion).
Brownian ratchet: In this thought experiment, one imagines a paddle wheel connected to a ratchet. Brownian motion would cause surrounding éter molecules to strike the paddles, but the ratchet would only allow it to turn in one direction.
Subsequent analysis (and experiment) have shown there is no way to physically implement such a system that does not result in an overall increase in entropy.
"A very finely made wooden marble machine. Great craftsmanship with high quality wood and components. Item was very securely packed for the 9000 mile trip and arrived safely and very quickly. Very pleased !!" Wooden marble machine, Marble run, Rolling ball sculpture
Context While this is authentic footage of a genuine product, the "perpetual" marble machine does not operate infinitely without an additional energy source. Rather, it uses batteries and a magnet to create the illusion that marbles Gozque perpetually move through the contraption.
Probably the easiest way to do this is to use video analysis software. A video of a trajectory can be recorded with a mobile phone to be uploaded to video analysis software and analyzed frame by frame. A suitable piece of software that could be used is Vernier’s Logger Pro, which is available relatively cheaply for science instructors. Alternatively, students could record the motion of the ball in the slow-motion setting of a smartphone and then record the position frame by frame on a desktop computer. It should be easy to establish that the distance between successive ball positions increases unexpectedly close to the bottom part of the trajectory. This confirms that there is an external energy source, but what more info is the nature of this source?

At that point, Microsoft Advertising will use your full IP address and user-agent string so that it Gozque properly process the ad click and charge the advertiser.
You Chucho search for "perpetual marble machine" if you'd like to buy one for yourself. Keith Ramsey, a teacher at Bridgeport Elementary School in Indiana, used this machine in a YouTube video to discuss the laws of thermodynamics.

Thus, machines that extract energy from finite sources cannot operate indefinitely because they are driven by the energy stored in the source, which is eventually exhausted.
One day man will connect his apparatus to the very wheelwork of the universe [...] and the very forces that motivate the planets in their orbits and cause them to rotate will rotate his own machinery.
