The concept of Maxwell's demon was proven to not be able to lower entropy because it creates more entropy in the process see link. What if instead of a demon there was just a small slit?
If a high-energy particle happened to slip through, wouldn't that violate entropy? Thanks, Max If a very high or low energy particle did happen to slip through first, entropy would be violated, at least temporarily. Additionally, according to quantum physics, higher energy particles have a more concentrated probability field - so they are thinner.
Max What if the change in this particle's state prevented further contact between the two objects? The higher energy concentration on one side could knock a door closed There has to be a better example but I can't think of one. When a lemon is cut in half you can see that it is actually made up of several smaller sections. For example this lemon is made of nine sections. Is this the same for all normal lemons? Does this relate also to the number of petals the lemon tree's flowers have?

How much can be extrapolated from the results of Nature's review of Encyclopedia Britannica and Wikipedia? How should the margin of error for the average number of mistakes per article be calculated? Is there currently a drive or WikiProject to improve the quality of the articles in question , or for that matter, does anyone maintain a list of WP articles mentioned in the media as needing improvement?
I would imagine a list of those articles would be good to have, as experts will be attracted to them, and they're also likely vandalism targets, so they should be watched and improved.
This is just a suggestion, but if it doesn't exist I'd like to start something like that. Did I deviate too far from science to be on the reference desk? I hope not. The decibel is a commonly used unit of sound loudness. However, according to the article, a decibel is a dimensionless unit. There are several variations on the decibel listed in the article, but I'm unable to figure out which one is correct. Which decibel variant is the correct one to use when talking about the subjective loudness of a sound to humans?
Or is merely decibel sufficient? Is the unit Acetabulum related to the same-named part of the human body e. Or is it merely coincidence? Part of the answer to the question is related to the structure of the data, and packing.
Data is being transmitted at the speed of light along the cable, right? It is going two ways at the same time. There are multiple parallel data, like in a TV signal, there is both audio and video, in parallel with each other.
Advantage of one over another is resistance to interference with the primary signals. Assuming you mean in terms of computer networking cable, thinwire co-ax ethernet tops out at 10 MiB per second, and twisted pair goes up to at Cat 6 1GiB per second - assuming you have the correct hardware on both ends.
Ethernet has more information. I'll note that, in principle, there isn't really a difference between the maximum data throughput of the two cable types, but as twisted pair was a much nicer topology, noone bothered designing and standardising aything faster through co-ax.

I suggest you look it up. Thryduulf , 15 December UTC. If you take one cubic metre of stones and crush them in a crusher to produce finer aggregates, what will the volume of resulting aggregates. Depends on the size and shape of the original stones, I'd say. For example, if you start with a single cubical stone with one meter edges, the answer would probably be a. If, on the other hand, you start with spherical stones 50 cm across, packed into the same one meter cube 8 will fit exactly , the answer is almost certainly c.
And of course, if you only measure the actual volume taken by the stones, not counting the spaces between them, then the answer is always b by definition. I was talking with a teacher and we came across the fact that a green bean could be a vegetable or a fruit and we were wondering which one it is. It is not a root or a leaf however it has beans and that means that they can reproduce and regrow.
Therefore i just need to know whether beans are a fruit or a vegetable. Thank You, Melinda. I would be most grateful if you could send your answers to this question.
I also would be grateful if you could provide names and e-mails of specialists historians, researchers, sociologists, political scientists, etc who could be interviewed by e-mail about this subject. You might also find useful info in the History of Space Exploration.
Many products and services originally developed for astronauts, such as powdered orange juice, powdered milk, microwaveable instant meals, subsequently found their way into every home. Related to that, look at what has happened with Spy Satelites. Today there are several commercially available views of planet earth connected through the Internet, where anyone can see detail that a few years ago was only available to the military.
Many millioms of people died in WWI and WWII and I would not try and justfie the loss of life but think where we would be now had it not been for their sacrifice.

The original asker of the question Do you mean that it is not possible to reduce the size? Just another query, Is it possible to do that in windows if not in the monitor? In principle, sort of. It depends on the electronics that are attached to the screen - these are required in a CRT, and not in an LCD, so probably not.
On the other hand, a software appraoch would work for an LCD - where you define the outer say pixels to be black, and tell the OS not to use them. I tried to find the answer on google by typing in the definition, but that didn't get me anywhere. I also tried dictionary websites, but I could't find one that would let me find a word by giving the definition.

Suppose there is a spacecraft traveling in space at near the speed of light. On it a person is traveling toward the direction that the spacecraft is moving in. If the combined speed of the person traveling relative to the spacecraft, and the actual speed of the spacecraft is greater then the speed of light, what would happen?
This would only be of observable magnitude with Helium, where Helium-3 a rare isotope is effectivly a fermion as the nucelus has a odd number of fermions , and helium-4 the common isotope is effectivly a boson. This is, indeed observable, and is what lead to the discovery of He It's noticable as a difference in boiling points.

Why does dipping a sleeper's hand in warm water cause them to urinate? That person will feel very relaxed and so the urge to urinate comes. I think the theory on the hand in warm water is that it causes the person to think they are back in the womb, where they urinated freely into the amniotic fluid.
How and when was tryptophan discovered? Who discovered it? Particles moving faster or slower isn't an effect of heat - that's what heat is. This also explains matter's expansion. Photons cause heat because radiation contains energy, and that energy has to go somewhere. After all, you can't use up energy. You can't create or destroy it. The concept that is instead important here is entropy. In particularly, the famous second law of thermodynamics , which states that in general, the entropy of a closed system increases.
Entropy is in many ways a measure of how close the system is to equilibrium, so if you want to decrease entropy locally by moving a system out of balance - e. This is also why there it's comparatively easy to cool down an object that is hot relative to its surroundings.
Who said it did? I didn't say question one and two were related. Anyway, thanks for the answers. Still not sure about a lot of it, though.
I am familiar with the conservation of energy. What I mean is what is happening with heat that particles become "Excited. Most importantly, though, I'll rephrase my last question. Why does a refrigerator have to be plugged into a wall? Heat is energy, so why must more energy be used in some form to cool the area inside of the 'fridge? Electricity or flame must be used to cool things. This seems counter-intuitive, as the air already has energy in it.
Why aren't we working on a way to tap into that energy? If we are, what is it called? Thank you for your answers and your time. I guess I'm not articulate enough to ask what I want to ask here. I know how refrigerators work and that molecules become "excited. Maybe no one does? To explain why the energy in heat can't be used unless there is a temperature differential, let's look at a potential energy analogy.
If you had a weight at the top of a meter cliff, you could push it over with a rope attached, and use the pull on the rope to power a dynamo during the fall, to get some electricity. Now, if the weight is still at an elevation of meters, but the ground is uniformally meters above sea level, with no cliffs, there is no way to turn this weight into energy, even though it still has the same amount of potential energy as in the first example. You could move the weight to a place where there is an elevation difference, but you would likely use more energy moving it there than you would get back, unless a cliff was quite close.
Similarly, you need a steep temperature differential where the two temperature regions are quite close to each other to extract more energy than is used up. Do any of you know if the 'paranormal phenomena' issue has been settled? I mean, has anyone proven them to exist or not? The reason I ask is that there are a lot of companys and individuals out there that make a buisness out of this. They are all seem to be doing good buisness, so I wonder if there's any truth to these things.
It is usually impossible to prove a negative, to prove that there is no such thing. I cannot disprove the existence of the tooth fairy even though I strongly suspect she doesnt exist. Clearly no one has proven that what you probably mean by "paranormal phenomena" exist. I can imagine lots of ways to prove the existence, but I confess I cannot think of a way to disprove the whole category.
What do think such a proof would be like? Court verdicts are often wrong as a result. Note that the existence of God could easily be proven by a personal appearance, or even a few of the Biblical miracles, like the parting of the Red Sea on a holy man's command, would be sufficient to convince most of us. The lack of such levels of proof since the dawn of science seems mighty coincidental to me. As for sudden cures, there are many explanations:.
I used to have plantars warts on the feet , then they went away. Had I been a religious fanatic, I could have said the chicken whose head I bit off was what cured me. Arthritis, for example, is measured primarily by the amount of pain reported. If someone thinks they are cured, either by visiting Lourdes or by biting the head off a chicken, they may convince themselves the pain level is reduced or eliminated.
The millions of people who visit Lourdes and don't have any "miraculous cure" rarely get much press. I believe many of the paranormal claims have been disproven. For example, the "cold reading" methods used to convince people a particular "pyschic" has a connection with the dead can be easily replicated by anyone who spends a few hours studying the technique.
For example, when someone points to a part of the audience and says "I'm seeing someone over here whose name starts with a J" Yet, when somebody says "that's me! It's hard to believe that the dead person is only able to tell the pyschic the first letter, and not the whole name. It also seems odd that no dead person ever tells the pyschic his name starts with a rarely used letter.
Has anyone made a computer in a Conway's life simulation? This reference from Conway's life :. Is this the whole story? Where do the late fees and interests go? Do they become a part of the banker's profit immediately? Or are they used to write-off the debt as well?

According to Lawrence Livermore Laboratories the maximum velocity for an energetic compound made of iron oxide and aluminum in a silica substrate is mps. There is even a paragraph which will appeal to those who so stongly disagree with Dr. Steven Jones. Nano thermite is an incendiary.
Explosives are classified as having velocities exceeding mps. The incendiary nanothermite allegedly found by Dr. Thomas Cahill outlines. I hope those who respond will take the small amount of trouble to read this article before exposing themselves as too reactionary to be bothered. Originally posted by Consequence Are you drunk? A collapsing building is such a case. Could you discribe to me the formulation for the concrete which you have used in constructing floor slabs for highrise buildings?
This is normally enough for high traffic areas and stands up well for most general uses. I would just like to know if a lighter mix could be used.
I also welcome you rapid reply. Originally posted by hdutton Could you discribe to me the formulation for the concrete which you have used in constructing floor slabs for highrise buildings? As mercury and methylmercury are fat soluble, they primarily accumulate in the viscera, although they are also found throughout the muscle tissue. When this fish is consumed by a predator, the mercury level is accumulated. Since fish are less efficient at depurating than accumulating methylmercury, fish-tissue concentrations increase over time.
Thus species that are high on the food chain amass body burdens of mercury that can be ten times higher than the species they consume. This process is called biomagnification.
Mercury poisoning happened this way in Minamata, Japan, now called Minamata disease. In the United States, the Environmental Protection Agency is charged with regulating and managing mercury contamination. Additionally, the Mercury-Containing and Rechargeable Battery Management Act, passed in , phases out the use of mercury in batteries, and provides for the efficient and cost-effective disposal of many types of used batteries.
In the European Union, the directive on the Restriction of the Use of Certain Hazardous Substances in Electrical and Electronic Equipment see RoHS bans mercury from certain electrical and electronic products, and limits the amount of mercury in other products to less than ppm.
The ban applies to new devices only, and contains exemptions for the health care sector and a two year grace period for manufacturers of barometers.
