Lorentz transformations explanation?

[guevaramartyr]

sorry, I'm not particularly well versed in this field. can someone explain the lorentz transformations to me?

Use Google to search for "Lorentz transformation". You will get a lot of hits explaining it.

If I traveled at 75% the speed of light (.75c) for 1 hour, did one hour really pass for me? No, only .66 hours passed for me, or 39.6 minuts. I found this by uising the lorenz transformation [itex]\sqrt{1- \frac{v^2}{c^2}}[/itex] The evidence is here...

The exact same goes for a decrease in length, and an increas in math exept its a factor using division for the latter.
sorry if the latex is a little off

Wrong. You would experience the same thing you did at rest (Postulate I of SR, Galilean relativity: Every inertial frame experiences the same physics). The unmentioned frame with respect to which you have that .75c speed would see your lengths shortened and your clocks slowed.

well that is obvious. Relativistic effects only occur from another frame of reference Even if time did slow down for you, you can't notice a difference. And it's not only clocks that slow down, its everything that time effects. I guess you just like the feeling of telling people they are wrong I think if you are going to tell people

You would experience the same thing you did at rest

you should atleast explain who does time really slow down for, it would help people understand better.

Lighten up, eNathan! You made a mistake (or at least made a very confusing statement); selfAdjoint just pointed it out. (It's his sworn duty as a mentor... he had no choice!)

Isn't that nice. But people here seem to criticize things that are right, wrong, and in the middle.

Yes. It's all very simple. Clock time can be conceptualized with moving rulers in such a way that the astonishing connection between space and time can be clearly understood.

But correcting and clarifying are not "criticizing". You are the only one criticizing here.

sorry to put you all through this, but i looked it up in the encyclopedia of physics lol. thanks anyway for being supporting.

I think it was pretty clear what eNathan meant from the context (i.e. if you see me travel at 0.75c for 1 hour in your frame, then in my frame the journey only lasted 0.66 hours)--selfAdjoint was just being a bit pedantic (which isn't necessarily a bad thing, even though eNathan understood it, others could have been confused I guess).

I see your point. And eNathan's as well.
