When someone order something don't he reduce entropy of the universe?

No. You can reduce the entropy of some system, but that will be at the cost of an entropy increase somewhere else. This is because it costs energy to put something in order. The TOTAL entropy in the Universe will always increase.
For example, the entropy on planet Earth probably remains more or less constant over millions of years - but we do so using energy, mainly from the Sun, and the fact that energy from the Sun radiates into space is an increase of entropy; much greater than any small change of entropy on our planet.

Why is entropy irreversible?
It's not that entropy can't be reversed, it's that the entropy of the universe is always increasing. That means that while you can reduce the entropy of something, the entropy of another thing must go up even more so that in total, the entropy goes up.
What does wasted energy add too?
Wasted energy will increase the amount of useless, or unusable, energy, and reduce the amount of usable energy in the Universe. The wasted energy is related to entropy - one way to express the Second Law of Thermodynamics is to say that there are irreversible processes (in terms of energy), another is that "entropy increases". However, entropy is not energy; it is not measured in Joule, but in Joule/Kelvin. In any case, you might say that when energy is wasted, entropy increases.Wasted energy will increase the amount of useless, or unusable, energy, and reduce the amount of usable energy in the Universe.

Can you decrease the entropy if yes then how and if not then why?
You cannot reduce entropy because entropy increases (Second Law of Thermodynamics), if you could, we could have perpetual motion. When work is achieved energy is lost to heat. The only way to decrease the entropy of a system is to increase the entropy of another system.
What does is mean to reduce something?
reduce something is to make the amount of something smaller. For example you can reduce your electric bill by unplugging the refrigerator.

Can entropy be zero?
I am not sure whether you refer to delta S (change in entropy) or entropy itself. So I'll answer for both.For S (entropy), which is defined by the function S=kln(omega), where k is Boltzmann's constant and omega is the number of microstates corresponding to a given state, the answer is no. Why? Omega (the number of microstates possible for a certain state) can never be smaller than one. Since Boltzmann's constant is a positive number and ln(omega) will always be greater or equal to zero, entropy will never be negative.However, when calculating delta S (change in entropy in a thermodynamic process), yes entropy can be negative. Remember entropy is essentially the state of disorder of a system since (on a macroscopic level) the natural progression of the world is from order to disorder. (For example, there are more ways to have a messy room than to have an impeccable, neat room). For the change in entropy to be negative just think of it in terms of the room analogy: initially, it was messy, but then it got neater. The state of disorder of things was lessened. Applying this to a chemistry example:CO 2 (g)--> CO 2 (s)An element/compound in a gaseous state always has a greater state of entropy (gaseous molecules are more free to move). However, an element/compound in a solid state has a smaller state of entropy because molecules in a solid are less free to move. Smaller state of entropy - greater state of entropy=negative entropy
What are the homophones for something learned and to reduce?
The homophones for something learned are "taught" and "taut." The homophones for to reduce are "adduce" and "deduce."
What scientific reason do you give for not changing eggs form scrabbled to poach?
Personally I wouldn't do that because I prefer scrambled eggs. I suspect the answer to this is the second law of thermodynamics -- entropy always increases. There is higher entropy in scrambled eggs than poached eggs. However it is possible to reduce entropy in subsystems -- air conditioners do it and a machine could be invented to turn scrambled eggs into poached eggs.
Is reduce a terms means to use less of something?
reduce
Discuss the implications of entropy to a Christian?
The universe is "running down," becoming randomly scattered and disorganized, tending to break down into its simple parts. Metals rust, parts wear out, dead organisms decay and turn to dust. The entropy of the universe is increasing.The Bible provides an answer. A great amount of energy had to be expended to produce such great organization. As one scientist states the problem, energy was not enough. If you are asked to "reduce the entropy" of your room (put it in order), you certainly need to put in some effort (energy). But just adding energy is not enough. You could let loose a bull in your room, and it would expend a great deal of energy; however, that energy would not decrease but would increase the disorder of the room. Therefore, scientists know that to produce order, energy must be intelligently directed. Evolution requires that atoms and molecules assemble themselves into increasing order, but the science of thermodynamics assures us that the entire universe, when left to itself, is converting to disorder. The Apostle Paul referred to this concept when he said through inspiration that the entire earth is "subject to the bondage of decay." The original state required an intelligence to organize the complexities of the universe.Christians, of course, have an answer to these perplexing questions: God. God is the Creator of the universe, the ultimate source of its energy and order. He created it with no entropy (no disorder). When man sinned, the universe began to increase in entropy (become more and more disordered). For Christians a discussion of energy, thermodynamics, and entropy is inspiring. These subjects invariably point us to the One who created the universe and sustains it by His power. Christians also know that His power will one day totally renew the universe and entropy will have no part in it.Christians need never be afraid of science. God is in control of the universe and all the laws of the universe operate according to His will and design. Christians should be confident that they have the answers to the perplexing questions of nature.Part 2The above attitude allows christians to ignore questions that are difficult and this leads to mental complacency."This is gods work. I must not question or touch this". Is their motto.When christians see difficult questions, such as entropy and creation, that is where they stop thinking and attribute it to god. They become intellectually crippled and refuse to make that one further step. It then halts progress until the shamen can integrate new knowledge into their mantra and dogma.Science in general, tries to explain and understand and make further progress and additions to human knowledge. Christians will only try to understand what they have been taught and integrate any new knowledge when the older beliefs become untenable.
What happens when you reduce?
You make something smaller. "Reduce" is another word for subtract.
Can the law of entropy be expressed as follows a given system when left alone in nature will always fall into disorder and never more order If not how should it be expressed?
Trying to reduce entropy or the Second Law of Thermodynamics to a catch phrase leads to all sorts of problems. In the case of entropy saying that things always fall apart, never come together, misrepresents the concept. Overall as an entire Universe things do seem to be following that rule, but at a local level (frost forming, atoms fusing in suns, life, mud puddles warming in the sunlight, evolution, etc.) things do go from simplicity to complexity. It would be better to state that an decrease in one part of a system must be accompanied by a greater increase in entropy in another. There is no prohibition on decreasing entropy. According to the Division of Chemistry Education at Purdue: "Second Law: In an isolated system, natural processes are spontaneous when they lead to an increase in disorder, or entropy." This all hinges on the definition of "an isolated system". An isolated system is one in which neither matter nor energy are exchanged with the surroundings (of the system). So, this is a system that is not "connected to" anything else.
