lol, gettin lazy in my old age. cheers guys rob

Hey all, just taking more tangents from my revision again and thought about the following: ok so the world makes one full rotation in 24 hours, which means it spins 15 degrees in 1 hour etc etc. so if i was to jump vertically in the air and hover above the ground for 1 hour and then falls back down the same line an hour later would i be displaced 15 degrees horizontally? whichi guess physically is about the size of france. i was only wondering this because im off to america in the summer and the flight there and back take basically the same time. anyway cheers for any input! rob

Hey all, would be a massive help if anyone could shed any light on the following question? i am trying to revise for my finals but cant seem to put my finger on the answer to this: Describe 3 ways in which x rays and gamma rays interact with matter - and what determines the minimum photon energy required for process? cheers!!!! rob xx

why is the earth held in orbit around the sun? this may seem like a fairly simple question but ive tried 'googling' it and nothing, any help much apprieciated! cheers

Hey, right wonder if any of you could cast your opinions on the following: i am currently a first year physics student studying in bristol university, i am currently at home over the break. i have a couple of homework pieces to be done but in an effort to avoid doing any actual work i have been pondering on some bits and pieces that have puzzled me throughout my first term. the first wonder i have is that of time. i have read alot in special and general relativity and from what i can gather if one was to accelerate ones self to the speed of light then one could live forever. what i put forward is that time is only the result of velocity. that is we as a universe only experience time because we are accelerating in one or more directions. this would then lead to a measurable time difference as the years went on. Now time is just a measurement of the distance between two events therefor prediciting this theory would be relatively simple. now i have only begun to look into this today and will tonight called upon the time between ice ages, as these times are very long and any difference would be significant. this idea may well be and probably is very rubbish but as an aspiring astrophysicist i want talk about any ideas. would really appreciate any feedback! thanks all, have a great christmas rob
