hi every all...
i need to know what is the main way for a pool to lose heat, is it by convection, conduction or radiation, and if we use a soler cover how much it could help, if it is fine to use from where we can get such of these covers, is there any recomended types or companies...

I understand that no scientist should claim to have all the answers. To think so would be arrogant, at the least. Nonetheless, do Evolutionists assume there must have been some begining to all, (wheather or not this "begining" had life)?

If evolutionists do not believe in an ultimate begining, they must believe in an "eternal-before", correct? If evolutionists do believe in an ultimate begining, then what is the source of that begining, (be it alive or not)? If evolutionists are undecided in this topic, then science would demand they had an open mind to any possibilities, Would it not?

My apologies for the multiple questions. I have just been inquiring more and more about science and its theories. I know about the many books, but it will take me time to read them all!!

Thank you. I appreciate any and all answers.

Does any one know any function, its derivative is the function itself. For example g(x)= e ^ x and g'(x)= e ^ x itself

Like, if a tiny piece of dust lands on a table, does it make a sound that's just inaudible to our ears? Do molecules that clash together make a sound?

I am interested in tons of detail and summary. As long as I get an intro, I don't mind more complex ideas being shared.
I'm looking for anything and everything related, since it's a vast science.I am quite curious and unknowledgable about it.
