I don't believe in the big bang theory. I am interested in what other people believe. So if there was a large explosion that led to collections of matter (planets/stars) - assuming the sun started out just as matter that was not burning ...I wonder how did the sun and other stars first ignite?

I need help to solve this riddle.

Person A has one amount of money in his pocket, Person B has one amount in his pocket.

If person A gives person B X amount from his pocket, person B will end up with 3 times more money in his pocket than person A.

However if person B gives person A the X amount of money person A will end up with 2 times more money than person B in his pocket.

How much does each guy have in his pocket, and how much is X???

Can someone help me solve this riddle??

For this question, the definitions of terms used are

Evolution = the development of species into different types of animals over very long periods of time. e.g. fish evolving into modern day birds. A fruit fly evolving into another species of fruit fly is too short sighted. Evolution here is taken to mean evolution from one type of animal to another type of animal and include theories in like character to the Cambrian Explosion.

Science = "systematic knowledge of the physical or material world gained through observation and experimentation." (www.dictionary.com)

Philosophy = "1. the rational investigation of the truths and principles of being, knowledge, or conduct. 2. the critical study of the basic principles and concepts of a particular branch of knowledge, esp. with a view to improving or reconstituting them." (www.dictionary.com)

I am aware the question has been asked before. However, I wanted to ask the question myself, providing concrete definitions of critical terms.

I've been thinking about this but couldn't finish up a proof yet:

For each x >0, define frac(x) as the fractionary part of x, that is, f(x) = x - [x], where {x} is the largest integer <= x.

Let p>0 be an irrational. Show that the sequence (frac(n*p), n=1,2,3....) is dense in [0, 1].

Thank you

Hi.
I have two problems that I need help with, please.
1) I need to classify the following equation as an identity, conditional equation or contradiction: sin x = tan x cos x
2) I need to convert the following equation to polar form:
2x - 2y = 1
Could someone please walk me through the solutions step by step and explain each step so I can understand how to do this.
Thank you.

It has been proven that the Earth, along with the universe, has, and is, expanding and is much bigger than it was 1000's of years ago. Then it is also proven that it will take longer than 24 hours for the Earth to completely turn in a full day . That means that it would take longer for the Earth to move around the Sun. Which means our days arent 24 hours and our years are longer than 365 days. (Daylight savings and leap years dont cover it....that is done routinely)

My best example would be a door. Does it use more energy to open it or to push it open again when it is closing? The object would be the same weight and have the same mass.
