So, nothing much to do with diffraction.

A 5% solution is near isotonic. Once it is in the body and metabolised it's no longer 5% glucose so it's not possible to say whether it's isotonic or not.

Well, that's that. All you need to do is tell essentially the entire copper industry that they are doing it wrong and they should be vacuum distilling copper in an unobtanium flask instead of their silly persistence in using electrolytic refining. You might also want to tell them why you think this "300K equals only 26meV. " is important. I'm still waiting for an answer to my earlier question re. vacuum distilling tin and silver; "Where, for example, would it be a better bet than electrolytic refining?"

Miscibility. Oil and water separate; alcohol and water don't. The oxides mix (and to an extent, react) with each other, so they are much less likely to stratify.

So, you cited it, but you can't justify it. That's not a very scientific stance. Why? It's still the same stuff once it's in the body.

I see the cows lined up in the field waiting for the farmer to come and take them for milking. I guess that's an accuracy of about 15 to 30 minutes a day.

Each wedge shaped bit of metal could be magnetised after it was cut to shape, but before assembly into a sphere. And it still wouldn't help. Imagine the lines of force round the magnet. As you put the next magnet near it the lines of force round each one still have to go from one end of the magnet to the other. So, once you assemble the whole sphere what you have is a bunch of magnets each with a closed loop of field round them and practically no external field.

Ant super intelligent life form could presumably fake a human artefact so perhaps the flower pot on my window sill is evidence of alien visitation. On the other hand, plenty of animals use tools and some of themadapt the tools to the purpose so we do know what some non human artefacts look like. What was the point of this thread?

That's obviously ridiculous; how do you put a number on "adictiveness"?

Why would they use expensive epoxy when they can use cheap concrete?

The mystery is why you don't simply accept that there is no way that a hover-board will work. it's fake and it always was.

You could make the metal wedge-shaped then magnetise it; that's not the problem. The problem is that it doesn't work.

Old chemist's trick (passed on to you all by an old(ish) chemist)

In fairness,an object's emissivity is wavelength dependent. It has to be because some things are coloured. https://en.wikipedia.org/wiki/Kirchhoff%27s_law_of_thermal_radiation

Neodymium magnets are real. You can buy them easily enough. But they won't make a board hover

In my experience, crystaline salt works better. I think the salt grains give the water something heavy to stick to

I'm not interested in whether you are a liar or you have been lied to. But the story is fake In particular this http://im46.gulfup.com/XkiqPo.jpg proves it; you can't use a He Ne laser as an ionisation source (not that it would help if you could).

Do you understand fake ?

Not really. If they are a stain they are (almost certainly) a solid so you need to dissolve them.

You might try pouring off the (mainly) diesel layer into a second container and adding salt to it then stirring.

The density of uranium oxide is a bit of a red herring. once the temperature is high enough the oxides will all melt and mix. If you leave a bottle of wine in the cellar the alcohol doesn't float to the top of the (denser) water to any measurable extent.

Just for the record, what do you think the minimum voltage drop across an electrolytic refining cell is? Only a project with the sort of budget that the Manhattan project had would consider using a mass spec to separate macroscopic amounts of materials. to do it for something as cheap as silver (or gold) would be bizarre.

It is fake. There are no hoverboards.

So, the original problem wasn't properly described. No wonder some of us thought it impossible.
