    Simple experiment with magnets

    There is no 'problem' unsolved with what you refer to as 'the second problem'. Numbers of individual small Magnets at the single domain level (as with larger individual magnets) do not typically self assemble into a composite large magnets with all small magnets universally aligned developing...

    Simple experiment with magnets

    The assumption about the orientation of magnitization is incorrect. From what is shown, the north and south poles are probably aligned with the largest faces of the blocks. , The action makes sense if 'up' is north (or south) and 'down' is south (or north). When the two broken pieces are put...

    Nuclear Explosion in Space… How would it work?

    . Total released energy from detonation in the vacuum of space would typically be less than the total released energy from detonation well within the atmosphere, mainly due to the pressure and mass of the atmosphete acting as a tamper effectively delaying disassembly allowing additional fissions...

    I Can an air-only refrigerant system effectively cool a freezer?

    . PV=nrT... If pressure and volume were to move in the same direction, i.e. both increasing or both reducing, temperature would not avoid change. If volume were decreased and pressure also decreased, temperature would have to have dropped significantly (assuming mass did not change). The...

    B Does the Expansion of the Universe Affect Gravity?

    Doesn't whether and how the universe is curved depend on whether the density of the universe is at the critical density and if not, how far off it is to which side? Wouldn't the curvature need to differ by some minimum amount in the correct way (spherical vs hyperboloid) to allow for such a...

    B Does the Expansion of the Universe Affect Gravity?

    Phinds, I would only apparently be laboring under such a misconception, if I accepted at true the solution suggested. In actuality you have misunderstood what I was saying. I don't believe there is a discrepancy, because I believe the expansion of the universe (space and the vaccum) models well...

    B Does the Expansion of the Universe Affect Gravity?

    Saying: "...stretching" of space is purely a pop-sci fantasy. Space is just geometry, not "stuff" that can stretch or bend...", ...doesn't fit well with the usual explanation for the apparent discrepancy between the observable universe being ~92 Gly in diameter but only 14.7 Ga old. If...

    B Faraday's disk and "absolute" magnetic fields

    Okay, I think a simple experiment can establish that relative motion between parts of the circuit is a necessary part to generate current and that rotation of the conductor around an axis parallel with magnetic field lines will not generate a current if there is not relatove motion between the...

    Why Do Ductile Materials Neck in the Middle?

    . I've been mulling this over and have awakened a couple mornings thinking about this. I think analyzing a round bar in tension as a number of concentric thin wall tubes with a very small center rod all in tension provides an advantage. . For a thin wall tube beginning as a right circular...

    Nichrome Resistance Wire Consistently Failing

    Have you performed an autopsy on the deceased heater plate? You should be able to locate the point where the circuit lost continuity. If not by simple visual inspection, then using a cheap multimeter will definitely get you there. You can also check to make sure both ends of the wire...

    B Faraday's disk and "absolute" magnetic fields

    What we have here is a failure to communicate. I don't have any reason to doubt general or special relativity. What I was saying was that if an interpretation of a theory doesn't fit observation then either the theory or application thereof must be flawed...with the implication that it must...

    B Faraday's disk and "absolute" magnetic fields

    "Particularly ojectionable": that is bordering on dogmatism. I was merely pointing out the possibilities. While I doubt relativity is inconsistent with the outcome of these experiments, it should never be beyond question. That is a basic tenet of sound science. What is far more likely is...

    B Faraday's disk and "absolute" magnetic fields

    Please point out the person claiming relativity has been contradicted. ..all I see are people claiming someone has state relativity has been contradicted.

    B Faraday's disk and "absolute" magnetic fields

    Like I continue to reitterate, yes relativity does provide robust predictions of reality. However if your interpretwtion of relativity has you predicting the rotation of the magnet alone meaningfully affects current in a classic faraday disk setup, then you are misapplying relativity.

    B Faraday's disk and "absolute" magnetic fields

    I don't see anyone claiming relativity is disproven. I would say that if you predict that spinning just the magnet in a classic Faraday disc set up will lead to current, then your implementation of relativity is flawed. Also, your claim that 'only with relativity can you correctly describe...
