Synchronizing clocks in two different inertial frames is possible through the method of clock synchronization by exchanging light signals. This involves establishing a common reference event that is easily identifiable in both frames. Observers in each frame emit and receive light signals to note the time of the reference event, allowing them to adjust their clocks accordingly. After several exchanges, the observers can compare their clocks and make necessary adjustments to achieve synchronization. Ultimately, this method ensures that the clocks in both frames remain synchronized and agree at all times.

question: show that you can synchronize the clocks in two different frames so that the synchronizations agree at all times.

Any suggestion on how to get started would be nice. Thanks.

Is that even possible? An observer in each frame of reference (providing they are inertial frames with some relative velocity) will see clocks running slower in the other frame.
 


To start, it is important to understand the concept of time dilation and how it affects the measurement of time in different frames of reference. Time dilation is the phenomenon where time appears to run slower for an observer in motion compared to an observer at rest. This is a fundamental principle in the theory of relativity.

In order to synchronize clocks in two different frames, we need to establish a common reference frame. This can be achieved by using a method called "clock synchronization by exchanging light signals". This method involves sending light signals back and forth between the two frames and adjusting the clocks until they are synchronized.

First, we need to choose a common event that will serve as the reference point for both frames. This event should be easily identifiable and occur at the same time in both frames. For example, the emission of a light signal from a specific point in space.

Next, we need to have two observers, one in each frame, who will be responsible for synchronizing the clocks. They will each have a clock and a light source. The observer in one frame will emit a light signal when the reference event occurs, and the observer in the other frame will receive the signal and note the time on their clock.

The process will then be repeated in the opposite direction, with the observer in the second frame emitting a light signal when the reference event occurs, and the observer in the first frame receiving the signal and noting the time on their clock.

After a few rounds of exchanging light signals, the observers can compare their clocks and make any necessary adjustments until they are synchronized. This method ensures that the clocks in both frames are synchronized and agree at all times.

In conclusion, synchronizing clocks in two different frames can be achieved by using the method of clock synchronization by exchanging light signals. This method allows for a common reference frame to be established and ensures that the clocks in both frames are synchronized and agree at all times.
 
The book claims the answer is that all the magnitudes are the same because "the gravitational force on the penguin is the same". I'm having trouble understanding this. I thought the buoyant force was equal to the weight of the fluid displaced. Weight depends on mass which depends on density. Therefore, due to the differing densities the buoyant force will be different in each case? Is this incorrect?
