In this Case, Given the Chaotic nature of true white noise, how could two systems communicate using white noise as a carrier.

Given that both systems would probably never coincide and therefore never be able to communicate.

Only two systems in which the white noise carrier is the same for the transmitter as it is for the receiver could communicate.

I tend to think that nature, quantum systems, biological systems use white noise as the carrier which is modulated by information.

Don't get me wrong, I am not talking radio technology here, but more like a statistical mathematical algorithm.

Therefore, only two systems which happen to coincide could communicate. Maybe this is what happens in complex biological neural systems and complex quantum states, this would also explain why such states cannot last forever as the coincidence cannot last forever.

I see this from a purely statistical mathematical perspective.

I have always wondered if there were humans on the Andromeda galaxy, just like us, in the Milky way galaxy....I also thought that they might be wondering if there are other humans out there (us)

I want to hear your opinions on this theory....

Such that if I look at a person (average/normal sized) on a cliff from 10 metres away or something, the moon will appear bigger than the person...

I wouldn't mind exact addresses/locations or even coordinates...

And don't try to find loop holes in the question so you can give a smart ass answer.

Scientific rxplorations at CERV using a 17-mile long partical accelerate of immense power could provide indications of other dimensions. This will help move science towards metaphysics. What would the discovery of other dimensions mean to you and to the world? What could be in those othjer dimensions? Life?

Could someone explain renormalization in quantum field theory? You may assume that I have a (very) rough understanding of what quantum field theory is. And no wikipedia excerpts please!

These are defined as light beings that are able to traverse the universe or connect with other dimensions, via wormholes ot stargates. Even Tibetan lamas were said to dissolve their bodies into pure energy and travel through the stars. The Sumerian word "Nibiru" meaning "crossing" could sctually have referred to a stargate, rather than another planet. What do you make of all this?

Every time I've heard someone describe entropy, they always use the analogy of a clean room, and say that the natural tendency is for the room to become messy. Now, I'm just starting to learn about entropy, so I don't see any DIRECT connection between the entropy of mixing gases, say, and the "entropy" of a pile of clothes on the floor. Is there some over-arching connection between entropy and all possible systems of things in the universe (e.g. the clothes on the floor), or is it merely an analogy?
Thank you

the Muhibbah company is a manufacturer of cylindirical aluminium tins. The manager plans to reduce the cost of production. the production cost is propotional to the area of the aluminium sheet used. the volume that each tin can hold is 1000 cubic cm
(1 liter).
1. determine the value of h, r and hence calculate the ratio of h over rwhe the total surfacearea of each tin is minimum. here, h cm is denotes the height and r cm the radius of the tin.
2. The top and bottom pieces of the tin of height h cm re cut from square shaped aluminium sheets.Determine the value for r,h and hence calculate the ratio h over r so that the total area of the aluminium sheet used for making the tin is minimum
3.Investigate cases where the top and bottom surfaces are cut from
(a)equilateral triangle
(b)regular haxagon
find the ratio of h over r for each case

Thanks to everyone who helped me...now i am facing another burden... i have solved 65 out of 70 problems but i am stucked with these problems... thanks to those who can help me.

the inverse of f(x)= 2x^2+4x-1;x greater than or equal to one
the inverse of f(x)=2e^x-3 (how can i solve for x in this fxn)
Solve for x

4^(x+1)+16^(x-3)=2
(log (2x+1) base 3) minus (log x^4 base 3) = 6
(log x-2 base two) minus 2 = (log 3 base 2) minus (log of (log x) base 2)
