Ellipsoid paradox: This paradox considers a perfectly reflecting cavity with two black bodies at points A and B. The reflecting surface is composed of two elliptical sections E1 and E2 and a spherical section S, and the bodies at A and B are located at the joint foci of the two ellipses and B is at the center of S. This configuration is such that apparently black body at B heat up relative to A: the radiation originating from the blackbody at A will land on and be absorbed by the blackbody at B.

"Just completed the marble run. I had to make a couple of adjustments & now it works great. The documentation on the other hand - needs improvement. Some of the illustrations aren't clear. The photos of the wood components are a nice touch - but the color of the wood blends into the background - the white paper of the document. Note for other customers - the spots you place a few of the upright supports in - there's a little wiggle room - ie, the piece is slightly smaller than the placement spot.

For the purpose of answering this question, I suggest that students should now propose potential mechanisms that explain what is seen and then work through the implications and plausibility of each mechanism. After this, groups of students could argue for or against some of the proposed mechanisms, a technique that reinforces concepts learned earlier in a physics course, but that also requires a deeper understanding of the concepts Figura opposed to learning by rote or memorization. It would obviously be desirable for students to have access to the toy shown in Ref.

"I have been collecting unusual things for a long time and this perpetual motion machine is one of my instant favourites. Great quality, the hidden on/off switch adds to the illusion.

To extract work from heat, thus producing a perpetual motion machine of the second kind, the most common approach (dating back at least to Maxwell's demon) is unidirectionality. Only molecules moving fast enough and in the right direction are allowed through the demon's trap door. In a Brownian ratchet, forces tending to turn the ratchet one way are able to do so while forces in the other direction are not. A diode in a heat bath allows through currents in one direction and not the other.

Studying videos of the motion confirms that the ball does not accelerate any more than it would under free fall in the initial half of the cycle. This Perro also be confirmed by dropping several balls through the hole in quick succession such that it would seem to be difficult to correctly time the electronics such that all the balls return to the starting platform.
