I have made a precipitate that I would like to know the composition of but I'm not a chemist so maybe some of you can help. If you dissolve soap, specifically ivory soap in hot water so that it is saturated with soap and then if you pour into that a solution of ferrous sulfate dissolved in...

no opinions eh? I'm thinking possibly ferric chloride or that in a mix of other things

Just wondering if anyone might have a guess as to what chemical this could be based on it's apperance when it is applied to wood. I found this picture on a woodworking site. This is some kind of chemical stain for wood. When first applied to wood it is a lemon yellow color but after a few...

So it's not carved in stone yet? There is still hope for infinity? :D YAY

That's a very disappointing development. Infinite would have been much more aesthetically pleasing to me. Oh well.

I have a simple geometry question hopefully I'm posting this in the right forum. I want to draw a simple logarithmic spiral using only compass and ruler or any other simple mechanical means. The requirement is that each spiral must be halfway from the center to the next spiral. Is there a...

Hi I didn't make any yet. I would like to try it sometime but have too many other irons in the fire.

Methanol? I tried dissolving it in denatured alcohol but that is ethanol isn't it? It wouldn't dissolve in that at least not that I could see. How much is somewhat? I'm not sure where I can get methanol.

there was a reply here. where did it go?

Well, the tittle says it all. Other than water, what will dissolve ordinary white crystalized table sugar. Specifically something that would evaporate and leave behind the sugar as a residue. Also something that is reasonably safe to handle.

Einstein never said that. go google time dilation and learn something

the way a wormhole works is that you fix one end at the present time and make the other end travel at near the speed of light so that it experiences time dilation. As a result of this, future people can enter the time dilated end and go back to the past where the past end is located. But...

How do you know we are not the anitmater and that it's the matter that is rare? Actually I kind of grasp what the OP is asking. He is saying there is only one kind of matter. And that matter moves away from us in time just like it does in the other 3 dimensions due to expansion. That idea...

Wouldn't the laws of thermodynamics prevent travel into the past? If you leave the present and travel to the past then you are decreasing the total mass and energy of the universe at this point in time and increasing the total mass and energy of the universe at some point in the past. And...

Thanks everyone. I'm no expert but I knew Planck was out there and would have greater resolution than wmap so figured I would ask. So we still have to wait awhile. :)
