maybee a reeealy small probe made of superstrings? While the average magnetic field of a photon should be zero, because it is oscillating + to - over time, at some point the field strength is at a maximum (say +) when the electrostatic field strength is a minimum (zero). So at that moment...

what I mean by an envelope A bar magnet's field extends to infinity, but if we take an arbitrary cutoff value, like, say, 1% of the highest field strength inside the envelope, then a physical boundary can be defined. The boundary is crossed when the test point moves far enough away from the...

If I examine a bar magnet's magnetic field, I can define such an envelope. Are you saying it is not possible to define such an envelope for the magnetic field of a photon?

Does a photon have a 3-D envelope of a certain size? (Assume a photon traveling in free space, and by 'envelope', I mean some space outside of which the field strength of the photon's electromagnetic fields drops below some threshold, say 1% of maximum.) If so, how big is the envelope? Does...

I make it 9, 2 and 2

Some things about the adaptation of humans to a meat diet 1. I spoke with a nutritionist once, who said that there are structures in the brains of developing children that do not develop properly without cholesterol that can't be gotten from plants. He thought it positively harmful to deprive...

Question rephrased OK, the QM world is admittedly unintuitive to macro-particles like me :confused: So can I try a re-phrase of the question? I think, but am not sure, this statement is true: The more you try and 'pin down' the location of a QM particle, the more it tends to 'spread out'...
