Taking Relativity Seriously

I don't think that physicists take relativity to its logical conclusions.  For example, the deal where two entangled photons are created and separate at the speed of light.  Then one is measured at some distance.  We wonder how its partner "knows" what was measured.  But the error is in looking exclusively from the human point of view.  From its own point of view, the photon lives in a timeless, distanceless now.  Emission, travel and absorption are all the same to it.  There is no need to communicate anything.

Similarly when a particle enters a black hole.  It is supposed to create the Black Hole Information Paradox by removing information from the universe.  Of course the info hasn't been removed from the universe.  It has only been removed from human view.

This is the same basic fallacy as "Columbus Discovered America".  The number of Europeans that didn't know about it didn't make America fail to exist.

Long & Thin or Short & Fat?

Ferrite rod antennas (loopsticks) present a design challenge because of size, weight, and cost.  One of the fundamental questions is long or fat?  These gents have the answer:

They found, through mathematics that's way above me, that the optimum aspect ratio is 20.  That is, for a given diameter, the rod should be 20 times that long.

Longwave Loop on Ground

Today I tried receiving 472 KHz with a loop laying on the ground.  Transmitting setup the same as last experiment.  Loop of 1 meter X 5 turns resonated by 2800 pF approximate tuning capacitor.  Max signal = 3 mV, noise a buzz at .002 mV.  Slightly less signal than last time, but much less noise.  And no need to dig holes.
