The work of famous scientist Galileo Galilei
surely you mean Dr. Galileo Galilei.provides us with a
question about time dilation and Dr. Albert Einstein's statement that
the laws of physics must remain the same in all frames of reference.

They did not all
believe in the principle of equivalence the moment the two lead
weights hit the ground.

which writers of textbooks
about relativity often use to show how the
Lorentz equations work.
Surely you mean Dr. Lorentz.Lorentz equations work.
If a weight is dropped from the top of a
train car to the floor, it falls a distance of y'. �In any
transformation equations this is always expressed as y'=y. � The
object travels the same distance vertically in S' as it does in S.
In Galileo's
Dr. Galileo to you.train car to the floor, it falls a distance of y'. �In any
transformation equations this is always expressed as y'=y. � The
object travels the same distance vertically in S' as it does in S.
In Galileo's
equations, it takes the same amount of time for the
object to travel from the roof of the train car to the floor in either
frame of reference. �t'=t.
� � In the Lorentz equations,
no, it is "Dr. Lorentz equations".object to travel from the roof of the train car to the floor in either
frame of reference. �t'=t.
� � In the Lorentz equations,
a clock in S', the frame of reference
of the train car, is slower than a clock in S, the frame of reference
of the train tracks.
t'=(t-vx/c^)/sqrt(1-v2/c^2). �According to this equation, it takes
less time for the object to fall from the roof of the train car to the
floor in S' than it does in S. �So how are the laws of physics the
same in both frames of reference?
� � �If a clock in S ticks once while an object is falling in the
train car, it will not tick in S' until after the object has hit the
floor. �This means that the object is falling with a faster velocity
in S' than in S.
� � �I am sure that some of our scientific friends
"Dr. scientific friends"!of the train car, is slower than a clock in S, the frame of reference
of the train tracks.
