Not so. Perhaps you should revise some mathematics, rather than insulting me (and others), since this is the second time you have done it, in this thread.

Because you have just described a circle with an infinity of complex numbers. Since there are an infinity of such circles, your would have an infinity of complex numbers filling every place in the list.

1) I will have to think about your model. 2) You don't calculate experimentally you measure. If you want to measure friction and MOI or other parameters, you can do mechanically exactly the same as you would do to take measurements. Add a load in parallel and measure the difference. The mechanical load can be a flywheel of known properties. The input can be measured and the time to run down from one speed to another, after removal of the drive, can be measured.

There are two separate ideas here. The terms water vapour and steam mean different things to different disciplines, physics, engineering, meteorology, geography/geology. The physics version is probably the best to stick to since it is consistent with lots of other aspects of physical science such as "vapour pressure". This asserts that the gaseous form of a pure substance is called a vapour. So on this definition water vapour is the gaseous form of water and it is invisible. Gasses do not form solutions. Assuming they don't react chemically with each other, they coexist with each other in any space or volume offered to them. Their pressures are additive. So this sort of water vapour and air is a mixture of two gasses not a solution of one in the other. This leaves the problem of the fact that water can form myriad tiny droplets dispersed through the air. These droplets are visible and comprise water in the liquid state. This is what clouds and fog is made of. Again the technical term for this arrangement is not a solution, but a disperse system. It is sometimes called an aerosol. The 'background' substance (air in this case) is called the disperse medium and the sunstance spread through it the disperse phase. These phases and mediums can be in any state here is a table. http://en.wikipedia.org/wiki/Dispersion_(chemistry)

The Boltzman factor and the equipartition system refer to different things. First the equipartition principle This should not be confused with a partition function Z, which may be related to the Boltzman factor. When a system has different modes of accepting and storing thermal energy, translational KE, PE, rotational, vibrational etc of its molecules, the EP asserts that the total energy is divided equally between all the modes. Each mode has an average that represents it, so there is an average molecular velocity that represents the average spped of the molecules at any given temperature and so on. But, of course, the actual velocities are distributed about this average. Further since the kinetic energy depends upon the square of the speed the distribution will not be symmetrical ie there will be many more slow molecules than the fast ones to balance the average. A partition function, Z, is an equation or function that describes this distribution. A particular partition function is the Boltzman distribution, where the Boltzman factor comes in to play. It is assumed that there are a finite number of molecules and a finite number of energy levels available to the molecules. The partition function describes the distribution between these levels. If there are only two levels (1) and (2) or between any pair of levels we label (1) and (2) the Boltzman factor applies. This is the ratio of the population or number of molecules in each level N1 and N2, in terms of the energies of those levels, E1 and E2 and the absolution temperature. [math]\frac{N_{2}}{N^{_{1}}} = e^{-\beta \left ( E_{2} -E_{1}\right )}[/math] Where [math]\beta = \frac{1}{kT}[/math] T is the absolute temperature and k is Boltzman's constant. The total can be reckoned by summing over all pairs. It should be noted that these calculations assume that the system is in thermal equilibrium.

What you are describing is known as the well ordering property. Integers, rational numbers and real numbers can be put into a continuous list in order of size a<b<c........ and so on., Where a, b, c are integers, rational or real numbers. But this is not true of the complex numbers that do not possess this property.

Thank you for that thought SJ. I often do just that when I move folks onto larger drives, or they just get more modern computers. So they always have their original available if they want it. External cases are OK for old drives, for backup or data drives that you only need accasionally. The trouble is that drive Windows demands a lot of empty woring space. Once the Windows drive has reached 50% full, performance is downhill all the way and the drive gets worked harder and harder. However perhaps the idea will be of use to someone else.

No they are usually bust and I have to fix them. This one came with an incorrect battery (wrong voltage), but was otherwise OK. I changed the 2x0.5G RAM modules for 2x2G of faster RAM from another dead laptop, deleted all old users, disabled UAC and now Vista is really flying. I am considering moving everything onto a larger HD as this one at 100G is 60% full. So far it has cost me £12 for a new battery.

I get given laptops (like the one I'm typing on now).

I didn't, one way or the other. I was offering a spin-off point that I don't think you made or denied. Feel free to comment on what I actually said.

Thnak you imatfaal. I'm up in Dundee for a few weeks so I was trying out codecogs to prepare for a reply to the statmech question. The text was as it came, I will only fiddle with it if it doesn't work.x I used to have a signature line If it ain't broke, fix it until it is.

The reason I included apple pie was that you wanted somethings that was widely represented on TV and Hollywood. Apple pie is synonymous with America and the american way of life and used to represent it. Otherwise any food would do. I suppose you could say something like bigMac or whatever.

The platinum catalyst is also capable of adding hydrogen to the carbon chain as well as the ketonic oxygen. But I'm sorry I couldn't properly determine you objective perhaps if you clarified it a bit some of the genuine organic chemists who log on later than I do might help.

It is easy to think that a being confined to a single space(like) axis would have more difficulty conceiving of multiple spatial axes. We have three so the idea of more does not raise any eyebrows, just questions like 'what observations support this idea'? However we only have one time axis so imagining additional ones is more difficult. By why stop at four?

MrLaymen That mixture of statements attributed to me that I didn't make, nonsense, inappropriately applied technical terms and plain incorrect statements belongs on the politicians' election trail, the pub after 8 pints or the trash can here.

Can't see why anyone is arguing about molybdenum. Any toolroom monkey or motor mechanic should be able to tell you about the unique worth of molybdenum disulphide in mechanical engineering.

The Earth has one moon. Is that finite enough for you?

Melting and other phase changes are only simple events for pure substances and some special mixtures (eutectics). I don't know if the OP has been back or is still interested in the subject ???????

Here is the copper nickel system phase diagram It shows that liquid copper and nickel are miscible in all proportions. That is they form a continuous system of alloys (new compounds that are neither copper nor nickel) in all proportions. That is neither is an impurity to the other. This is the simplest form of phase diagram and the melting point curve is a straight line along the solidus line.

Thank you fuzzwood +1 I have now put my post right.

I stand by my method, but this thread is not the place to discuss teaching methods, except to say that it has achieved great success preventing medical drug errors for medical practioners, thereby saving lives. I would be happy to discuss further in another thread.
