1. Dissolved Air

so how wring would it be to assume that the air in the glass has the same compressibiliity as the air around us. Would it be valid for making a simplified model..?
2. Dissolved Air

so you say that the air is liquid? Sounds interesting... But doesnt the temperature of air has to be quite low in order to be liquid?? Also, would it be valid to do the following: Lets say we have the compressibility of air (C.a) and the compressibility of water (C.w)... If we are given...
3. Dissolved Air

but is it still gas? is it tiny tiny bubbles? and then, would it affect the compressibility...
4. Dissolved Air

I have a question regarding a project I am working with currently.... Air that is dissolved in water (there always is around 0,004% I think, in normal pressure and 20 degress celsius), is it "physically dissolved"? I mean is the dissolved air still gas or is just air-molecules "trapped"...
5. Air in water

I'm currently studying the phenomena of air bubbles in water affecting the sound (as it affects the speed of sound) produced in the water... I actually have a model for how the speed of sound should alter with the amount of air in it... but I've got som problem with a thing I found out...
6. Liquids with different densities

but can the porperties and behavior be predicted by a model or something...? like the wave speed of it, the thickness of it etc...
7. Liquids with different densities

that helped alot:) was wondeirng further, what would happen if there would be two liquids with different salinity instead.. they would although thermal equlibrium not have same density... so would they mix-up by diffusion eventually by time?
8. Liquids with different densities

indeed, it is so... but my question is why the two liquids dont mix-up... which forces keep them apart..?
9. Liquids with different densities

I have always wondered why liquids of different densities dont mix up if put together with caution. As if you have a glass halffilled with cold water, you can with caution add another layer of warm water above the cold. You will see a clear boundry between the layers. Is this something with...
10. Paper bend in space

i just read through this thread (breifly, so excuse me if I repeat something), and couldnt resit posting my opinion.... I belive that the paper will Not bend... argument are given that it has a distribution of mass, and that this will cause the paper to bend. But that isnt true at all, as...
11. Importance of zero

sorry to disappoint you but n^0=1 isnt true for n=0... 0^0 is undefined and according to me (and many other) just the same as 0/0...
12. I name this number the Near Integer Ratio Rv

i just discovered a cool thing.. if we use this instead: (1+\sqrt{2})^{n} than we will get the cool thing that, at n= even numbers, we will get an answer just below an integer with 999999........ as decimals... but if we have n= odd number, the answer will be just above and integer with...
13. I name this number the Near Integer Ratio Rv

didnt find anything corresponding on that link (might have missed it)... quite a fasciniating number...impressive.. i dont get \frac{a + \sqrt{b}}{c}... becase if i set a=4 b=5 c=6 I dont get that sort of cool number... actually, i didnt get any number like that by that method. what did you...
14. Importance of zero

I "threw" zero off, not onto, the line of numbers.... I'll let zero exist as a concept but not as a number. So when you subtract tvo equal numbers you get the concept zero, which is nothing. Similarly, if someone asks how many points exist on a line, the asnwer will be the concept infinity...
15. Importance of zero

I'll have to confess that that is a little problemtaic.... but for the moment, let just throw the result of x-x of the line of numbers... if something equal nothing, it doesnt exist on the line... at least for the moment... will think if I can get a better solution...
