In attempting to explain QT to interested students, it seems like light waves in the double-slit experiment, and in the Three Polarizer Paradox seem "mixed-up" about whether you are dealing with one of Maxwell's waves, or one of Schrodinger's waves. Which is it?-And how can we know? Einstein...

Arrow of Time poll-entropy aims the bow Could it be increasing of Entropy that points the arrow of time? We don't see time running backward with all of the smoke heat, light, and ash coming back together to produce a fresh log in the fireplace, or chicks going back into eggs that are taken back...

In the 80-0 case, some of the momentum of the 80 car is transferred to the 0 car, which then will accellerate from 0 to its final constant velocity. Which pair of cars would cost the most to repair? I think the 80-0 collision, when the directions of vectors in the 40-40 case are kept the...

If our space was imbedded in a higher dimensional space with an additional orthogonal space dimension, and a sound wave traveled with a wavefront perpendicular to this additional dimension, what would we experience? What could we measure? Thanks, Ron

To anyone who might know: If we add an additional orthogonal spatial dimension, w, to the usual 3 spatial dimensions plus time, x, y, z, t, does anyone know if the physics of this x, y, z, w, t -space is different in fundamental ways? For example: suppose a hypersphere rotates around the...

Quantum Weird - Want more! These Quantum Theory "weird" experimental results and strange implications of theory are a striking feature of this branch of science. Would any of you be able to contribute your own paradoxes and points?

To everyone who was kind enough to offer their help with my puzzlement about "Does the Moon exist when nobody looks at it," please accept my sincere thanks for your replies. You have given me much to think about, and I am grateful.-Ron

Dear selfAdjoint and Spin Network, The probabilities of Quantum Physics seem different than the probabilities of the macroscopic world: the probabilities of the Quantum World do not seem to reflect the same thing as "classical ignorance" about a throw of dice, but rather seem to be a kind of...

To all interested persons: Do you think the statement: "The Moon does not exist when nobody looks at it" is a dramatic way of saying "The Moon does not exist in a definite place when nobody looks at it" ? Or is this still too oversimplified? Am I correct in supposing that to every point in...

Dear Vanesch, To see if I understand: You and others are saying that it is not a question of whether or not the moon exists, but instead, by The Heisenberg Uncertainty Principle the question is whether the Moon occupies a specific spot in x,y,z,t space-time if it no one makes an observation? -Ron

If the Moon did not exist when nobody looked at it, then wouldn't the gravitational attraction disappear too? If that happened, the tides would change (at least). Does our experiencing of the gravitational effects of the Moon amount to an indirect way of making a measurement (observing the Moon)?

Have finally gotten Mermin's paper to open, and am studying it and Dr. Chinese's discussion on his site. This is deep stuff. Fascinating and amazing stuff. Thanks. If you guys think I'm mixed up or confused, please tell me. I have no axe to grind or point I need to make. I just want to learn it...

Hi Dr. Chinese, Please help me understand if this Moon-existence issue results from the whole take on the Copenhagen Interpretation, or not. I think I see now how it is related to EPR and Bell's, because the moon-existence thing is related to the question of whether there is or is not a "deep...

Hello Tardis, Dr.Chinese, and Spin Network, Thank you for your prompt replies. It is my pleasure to meet you. I downloaded David Mermin's paper, but could not open the file. How is the question of whether the Moon exists when nobody looks at it tied into EPR and Bell's Theorem? Can you show me...

Please help me with this. Can anyone direct me to the specific mathematics that is interpreted as saying that "the Moon does not exist when nobody looks at it." Is there any book or discussion of the actual math and physics of this? What specifically was Einstein reacting to when he said: "I...
