Some Extra Thoughts (1)
This section is not about Special Relativity itself,
but about its adoption.
There are many kinds of natural clocks, like the day, month, and year.
There are also many kinds of man-made clocks, like mechanical, crystal and atomic clocks.
Among all these clocks, which of them runs like a light clock,
using the mechanism of a round trip on a straight line?
Does this specialty of light clocks makes them better than other types of clocks?
Even if it has been agreed that light clocks are the best,
we are still left with one big difficulty.
Among all the light clocks, each pointing in a different direction,
which one's time should we trust?
