One of your best bets is probably to get on ebay or amazon and get an introductory book or something. You can pick up some second hand ones for real cheap and you'll get everything you want in one place. The internet can be a hard place to search in terms of maths and usually only really...

Hello! :) A few questions out of pure interest here that I figured someone on the forum will probably be able to help me with. Just wondering, in terms of maths, has there been any relationship found between the speed that you are traveling and the difference in time (from how it slows...

Hmmm...yes. But what about them times where you just know its been exactly the same before? Surely that's a little more than familiar with the situation. But then, I guess, that can be down to personal experience.

Hello. This has been a topic on my mind for a very long time now and I thought I would share my ideas here in hope for some feedback. (Note: I'm not sure if this is in the correct section, please move, if necessery!) I am not jumping to any conclusions here but just wanted to express an idea...

Interesting idea. I, too, have had similar ideas to this. Be this an illusion, an alternate world or a test, I believe this is not the world we will be living in after death.

Very interesting idea, but I always percieve black holes to be extremely massive and chewing up stars, rather than a few atoms a time. It still does not say how they think the tiny black holes were made at the big bang...but then again, everything was made as this point and we do not know how...

Hmmm... So, if 'large' black holes are remnants of collapsed stars, where do these Tiny black holes come from? They seem to have left a lot unanswered here! :)

Yes, good topic. In my book, also, it talks about this but doesn't relate any particular vibrations as certain particles or specify how many there are. Would be good if I could get a better understanding too! :)

bump please sorry, I know I am annoying I just need the answer so bad

i am using frequencies of 1000Hz and 3500Hz and some cardboard around 2mm thick by using an oscilloscope to see the amount that comes and reaches a microphone...the 1000Hz gives much bigger results showing more lower frequencies get through.

yeah, i know all that but that doesn't explain why they cancel out :confused:

what do you mean by canceled out? as frequency is about how fast the atoms etc. vibrate? and amplitude the size of the vibration? can you explain please! :)

anyone please?

Ok, so say you had 2 identical materials you pass both a high and low frequncy sound through it, yet the lower passes through easier...thats what I meant to ask. Probabaly didnt make it clear enough :P

This is a question that has been bugging me for quite and long time and I have been searching on the Internet, but having no luck. So, why does lower frequency sound pass through materials much easier then higher? Thanks, Rich
