Evolution or natural selection refers to "weeding out" process, correct? If so, then natural selction actually has to critically think. If it critically thinks then it must have a brain. Example: a farmer goes out to farm he notices that his crops are bing chked by the weeds, so he gets rid of the weeds, "weeding out".

Evolution sounds pretty smart or could evolution acutally be G-d, may he be blessed?

A retailer spent $48 to purchase a number of special mugs. Two of them were broken in the store, but by selling each of the reaming mugs for $3 above the original cost per mug, she made a total profit of $22. Construct an equation that will allow us to solve for the number of mugs, denoted by n, that were originally purchased
a. if the price for n mugs is $48, how can we express the cost per mug
b. We are told that the retailer, in order to make a specific profit, sells the remaining mugs for $3 more the the original cost per mug. Using this information, and your answer to step (a) how can we express the selling price per mug?
c. since two of the mugs were broken in the store, how can we represent the number of mugs that are available for sale?
d. Use the answers from step (b) and (c) to construct an expression for the amount of money made on the sale of the remaining mugs
e. Write an equation that states this relationship between the money made, the cost, and the profit

If god created it, why? Why such a big big thing ? that the purpose?
If it is not god, How?
Anywayz....Is god what we think it is(hindu,muslims,etc)....or it is just the 'energy ' that always prevails in the universe(no brain, hands...just pure energy)

considering the function f(x)=1/(x+1) and A.M.>G.M.
prove that
(X1+X2+X3+........+Xn)/(1+X1+X2+.....+Xn)<=X1/(X1+1)+X2/(X2+1)+...+Xn/(1+Xn)

where X1,X2,..,Xn is non-negative real number

Assume that you invent a time machine that lets you go back and forth in time. You go back in time to prevent a problem that happened in your life, then come back to the present and the problem is fixed and things have changed. Why did you have to build a time machine in the first place? The problem would have already been fixed by the future you when you were younger, so you never would have had the problem in the first place. You would have lived your life without the problem, never knowing that it would have even happened, assuming your present self didn't talk with your past self.

Is time travel this confusing all the time, or am I putting too much thought into it?
