Dear George,
Thanks for taking the time to respond.
I understand how observers A and B may calculate from light or radar signals that when rod CD is approaching them at speed, CD appears shorter than AB, with an apparent length of 4 feet, rather than its physical length of 5 feet.
However if A...
PS I see now that this is how the mathematics must work out. However I still struggle to picture the physical reality of a situation where, even though the clocks, rods and observers pass right alongside one another, the observers on the two rods cannot agree on anything - the observers at A and...
Dear Friends,
Discussion of the Einstein's Special Relativity clock paradox is often complicated by the role of accelerations and objects following curved or polygonal paths. In the following example considers the clock paradox in a situation which only involves linear motion.
Imagine a rod...
