Physics question about time dialation

Hi I was wondering about how fast do you have to go before time dialation comes into effect...my friend is in physics and he was mentioning something about it yesterday during some drunken babble. I wanna see if he actually knew what he was talking about

P.S. I'am no Qauntum physics professor so I don't know alot about relativity

    This has nothing to do with quantum physics, but here's what I know...

    It's not as though relativistic effects "kick in" at some critical speed. They are always applicable. It's just that they aren't noticeable at everyday speeds.

    Now, if you want to know when relativistic effects are noticeable, that would depend on how sensitive your instruments are.

    (insert classic story about the airplanes with atomic clocks proving relativistic effects at the nanosecond level :tongue: )

    An interesting physical consequence of time dilation has to do with the flux of mu mesons that strike the earth - more of them strike the earth than can be accounted for by a nonrelativistic treatment of how far they travel from the primary pi meson cascade in the upper atmosphere. Go special relativity :)

    I did physics 101 last spring and the midterm was a joke, I never studied in the class and I got an A.

    the sad true is that I figure out how to do all the questions AFTER the midterm... :(
