i have a pure hatred for the book and believe that it should be burned. *hugs jacaranda* from my understanding, what they do is that they have 2 atomic clocks. one stays on earth and one goes on a space shuttle, which travels very fast. according to STOR, their should be differences in times...

yes my mistake... gotta do more maths:chainsaw:

:rolleyes: i havent been printing those books you know... :p :D

ooooooooh! i see it. that was the missing piece that the contexts2 didnt cover. that links the distance and time for me:) i would have still liked another example tho :(

hmmmm i would do it by graphing. this way of graphing should be covered in 3u.

YEP, thats time dilation. i know that... [i didnt get the point of you posting taht dotty :confused:] ++++++++++++++++++++++++++++++++++++++++++++++++++ what is an evidence of length contraction?

aargh! i have done that trial paper...it is so shit! 60% of it is on M&G....wtf!?!?!?! yep thats right. you basicalyl need to talk about: -the limitations of the power that can be produced. -heavy machineries usually utilise large amounts of power. you had that pretty much covered. :)...

aaargh! hate that book... *reads* ok...but cant this be due to time dilation? thats one of the shittest piece of explanations i have read..... it basically says, the muons last longer, so that shows length contraction???? i dont think its a valid explanation. they are relying on the...

hmm...i think you're wrong...or i'm not understanding you well. is it anywhere in the texts? m----------->detected but due to high speed and length contraction m---> detection that is a total contradiction to time dilation:p. the muon travellign at high speeds will be detected...

ahhahah that is brilliant... now all i need to do is to learn chinese ;)

it depends on what you define as smartness. you cant be naturally smart....being smart, personally, is being close to your own intellectual peak, which you cant reach without hard work. you cant compare yourself to be smarter than others coz you are beating them. they might be already...

no it actually helps to stay on topic as jac wanders off sometimes....

how can u use muons for length contraction?? they measure their lengths??!?! do explain. if they ask for 2, and the muons can be used for LC, then i will use the atomic clocks for time dilation

i'm assuming that you have been to bob emery's site.

so you will write "SOAP" on your pencil case? :p

i was doing a past paper and there was a question which asked to give recent evidence of time dilation and length contraction. for the time dilation i used the muons example, but for the length contraction i used a car moving past you at high speeds...*cough* shit *cough*. does anyone have...

all the questions... i did chap 7.4 and 7.6 in 4 hrs....dont think i did like chap7 and another one in 4hr :p you should be able to go through the chapter, if you start now, by tonight.

do all of the exercises in arnold...you'll learn that way. it took me about 4 hrs(with breaks) to do 2 chapters and understand the stuff. so it wonttake that long for you.

what other ones do you/others have? :)
