Why is it that if you actually entered the sun's core,all time would stop,or speed up?

is there yet a mystery about partitions? where can i find some lit. on the subject?

A few days ago my physics teacher told me that to find the magnetic field's direction in a wire you put up your right hand and whichever way your fingures bent was the magnetic field's direction, or at least that is what I understood. When I questioned him why this was the case he told me...

1. What happened in 1961 that will not happen again for over 4000 + years? 2. A man wanted to enter an exclusive club but did not know the password that was required. He waited by the door and listened. A club member knocked on the door and the doorman said, "twelve." The member replied...

Hi, Let's talk about Prime Numbers. Still an unsolved mystery, I don't understand why it's still unsolved. Has anyone discovered why its hard to find a pattern? Or is this a silly question?

Do they really form from fruit going bad... or do they COME To the fruit.. I don't understand how they would form.. from just fruit.. =-/

It is said that most mass in the universe consists of dark matters which don't emmit light. What is the difference between dark matters and planets? Thank u.

Why does Carbon 12 in dead tissue ''remain'' undisturbed?

I would like to know what sigma is and what it does. What is sigma? What does it stand for? How does it work? Do you have any examples of how it works? any help would be appreciated (im not sure if this should be in the calc section or not)

So what causes this? I was at a clinic the other day, waiting on my girlfriends mom to get out, and was reading a big-muscle-guy magazine. I was looking at the performance enhancers/weight loss formulas/muscle building/etc in there (do any of these really work?), and I noticed ads like this...

gravity must be the most confounding thing to science ,we all know its effects, but no one knows its mechanics, what is the most up to date theory, theories?

Does anyone know the workings behind those little scanners that department stores use...you know, the ones that they can take off and aim at the barcodes on heavy things? I know the barcodes themselves with the thickness of the lines and stuff represent the number that usually appears right...

stars are formed from gas clouds, these gas clouds posses potential energy and kinematic energy, they may also exhibit a density contrast, theory tells us that collapse of the gas cloud starts when PE overcomes KE, but i can find no explanation for the trigger to this collapse ,put another...

Recently in Chemistry we have been doing about how it is possible to identify carbon compounds by how many proton environments there are around a molecule. For this we look at graphs with various peaks dotted around them, this is not what bothers me, what bothers me is that some of these peaks...

This came about on a test today (we have handed it in) and it just got to me. I didn't think it was hard until my teacher made an outrageous claim. Here goes nothin: A hammer strikes a nail, and the nail goes in .8 cm. On the second strike, it will go in .7 cm. It is a geometric sequence...

You know guys, the planets is composed mainly of two types of rock material, Fe-material( siderolites) and the stony element (aerolites), these are heavy elements and available in the apace, which formed planets and stars within 1-2 billion years just because there were two Big Bangs, one...

Firstly, just a high to everyone, (first post, aye). Now, everyone has been saying that FTL Travel (Faster than Light) and even the speed of light is impossible. (dammit... ) than how is it that light can go at the speed of light. Now, for some touching back on the SOL theory. As you...

Why is there never thunders during winters? Shoudnt the cold air be even more conductive?

The question is: If a sprinter running at 10 meters per second could convert his kinetic energy into upward motion, how high could he jump? How do I solve this if I use the KE = 1/2 mv^2 I don't know what the mass is?

Ok I am not especially knowledgeable in thermodynamics or physics so I am sure the answer to this is quite simple. However to me it is quite a mystery. This is my thought. You have a cylinder filled with water; above it on supports is a solid object the exact size of the cylinder. Through...

Va Va Voom! I know a lot of the British people have seen the new Renault Clio adverts however I am not sure whether it is shown in the U.S. Anyway Thierry Henry (a famous French footballer...AMAZING) goes on and talks about what is Va Va Voom and what isn't Va Va Voom. I was just...

A question for Monique and anyone else who knows this material... Everyone born into my family has blue or grey eyes. Even when my mother's sister married a brown-eyed man, their children had blue eyes. Every single person born into our family has eyes of some shade of blue. Now, I don't...

I am very eager to understand what energy really is, thought no one really does. Are there more than one definition of energy? Is energy a property within all objects and thereby unifies all objects? Is it true that every object has a potential energy?

Why is the speed of light a constant?

Please take a look at these lines which demonstrate my problem in a korn shell terminal: First I defined var with a newline embedded in it. I printed it and, as expected, got abc def. I printed the same thing to file1. Next, I edited it using the pattern operator ${var//\\n\} to...

I first read this story in New Scientist when I was collecting it. Here are some highlights: The article has been reposted here: http://www.you.com.au/news/362.htm and in many other places. Any comments?

It seems to me that this is just a simple algebra problem, that doesn't have much to do with waves, but it's the only problem on the homework that I can't figure out. :-/ I know there's an easy solution to it, but I keep getting the wrong answer. Anyway, here it goes: A seismographic station...

I have an assignment free night and thought I would make a post that hopefully hasn't been made before. A discussion of perfect numbers: A positive integer n is said to be perfect if n is equal to the sum of all its positive divisors, not including n itself Alternatively, if σ(n)...

In the experiment that I did today, there's a very strange step. After mixing two solutions in a beaker, according to the lab manual, we needed to scratch the bottom of the beaker using a spectula so as to help forming ppt. My question is why does scratching the beaker help forming ppt?

Sometimes when I am driving I make myself the following questions. Why do the front windscreen of cars steam up? What is the physical reason? and what is the best way to eliminate the steam? I have heard many theories about the cause and how to act. who knows the right theory?

Question posed: Julia is as old as John will be when Julia is twice as old as John was when Julia's age was half the sum of their present ages. John is as old as Julia was when John was half the age he will be 10 years from now. How old are John and Julia...

http://archive.ncsa.uiuc.edu/Cyberia/NumRel/GravWaves.html Eddington was not the only skeptic. Many physicists thought the waves predicted by the theory were simply a mathematical artifact. Yet others continued to further develop and test the concept. By the 1960s, theorists had showed...

Why is it said that a black hole is a literally bottemless pit in space-time? If it weren't bottemless, then the singularity inside would not have to be of infinite density. I'm not sure if I have missed anything important, so PLEASE help!

I was reading In Code by Saray Flannery,one of the problem in the book bothered me, it is not the problem itself, it is the solution. A Party Trick If someone tells me 2, 2 and 3 are the remainders when she divides her age by 3, 5 and 7 respectively then I can work out her age. Solution...
