A Revolutionary Idea: Rethinking Time Measurement in Physics

Click For Summary
SUMMARY

The discussion centers around the assertion that "clocks do not measure time," a claim made by a participant with a Ph.D. in theoretical physics. The argument is supported by a thought experiment involving an ideal clock, which emphasizes that the readings on the clock are independent of the observer's frame of reference. The participant argues that clocks measure the "invariant interval," a concept rooted in Einstein's theory of relativity, rather than time itself, which they claim is an immeasurable variable. This perspective challenges traditional views in physics and calls for a reevaluation of how time is conceptualized and measured.

PREREQUISITES
  • Understanding of Einstein's theory of relativity
  • Familiarity with the concept of invariant interval
  • Knowledge of proper time versus coordinate time
  • Basic principles of physics measurement
NEXT STEPS
  • Research the concept of invariant interval in relativity
  • Study the differences between proper time and coordinate time
  • Explore the implications of time measurement in modern physics
  • Investigate historical perspectives on time measurement pre-Einstein
USEFUL FOR

The discussion is beneficial for theoretical physicists, students of physics, and anyone interested in the philosophical implications of time measurement in science.

...you totally missed the point that commutation could not possibly be an issue. :confused: I can only interpret that as evidence that you had no idea what \vec{\Psi} stood for. :frown:
Or perhaps you simply don't understand my comments? I mean, forget the philosophy, I believe that I made some valid points on your mathematics and you seem to dismiss them entirely out of hand because 'I didn't read it' - as you would well know of course.
If you knew what \vec{\Psi} stood for, how could you have possibly considered commutation to be an issue?

And I am going to presume you just didn't read my post any farther as you didn't comment on any of my other responses (I do believe I responded to all of your criticisms which is more courtesy than you have chosen to give me.)

Sorry, but I've had enough of this. I get enough arrogant old scientists at uni, I can't be fussed to deal with another one.
Well, I can certainly agree with that. As I said earlier, talking to me is not going to provide you with money or fame and, if you have as much difficulty following your professors as you do following me, you need all the time you can lay your hands on. Physics is a rigorous subject and one needs to look at the details not just the philosophy.

Have fun and good luck – Dick

PS no offense taken!

k finally read through all of the posts on this thread and i still think my theory is correct.

yay i win something don't i ?

You're right--I don't find any problem to look at there!
Your logic seems to be this:-the readings on the clock are the same in every frame--i.e. the readings don't reflect the time in moving frames-so clocks don't measure time.QED.(let me know if that's not your logic)
To my mind you have to have some measure of time and a clock is a good one at that.If you start out with that-- the clock does measure proper time and there is no reason why that should agree with the proper time of other frames.

Strange, I am not surprised at all.

ok now I am only a 19yr old withprobably no where as much education than any of. Yet i still do understand. here is something to think about with ur clocks, a clock has been said to not be able to measure time witch i believe to be correct. what if in stead of thinking of a clock as a measuring tool look at it as a reference. a clock let's u know what time it is where the clock is located( as long as the clock is set correctly according to the parameters of the ultimate mass it is on or in i.e. a planet moon star space in general) not how long it has been, the measurement happens in ur mind or u could say u calculate how long is has been or how long until another specific time.
i hope someone can give me some kind of opinion on this thought
