Re: [Phys-l] Teaching Special Relativity



Quoting John Denker <jsd@av8n.com>:

The analogy to special relativity is direct and profound: When folks
think they are measuring a Fitzgerald-Lorentz contracted ruler, or a
dilated clock, or a velocity-dependent mass, they are not measuring
physical reality; they are only measuring a shadow projected onto
some particular reference frame.

Measuring the length of the shadow cast by a meter stick is physics. Similarly, for measurement on electric field or magnetic field. One should be consistent...
