Thats great and all, but I asked about degaussing ships. As far as I know, magnetic mines detect a ships magnetic field, then it checks the ships *acoustic* signal, if the signal is not registered with the mine as a friendly vessel, KABOOM.

Degaussing ships?? Does anyone know how ships are degaussed exactly? I know that basically very thick electrically conducting cables are wrapped around perpendicular to length of the ship. Large currents are then sent through in an effort to cancel out the ships magnetic field. If anyone...

In the first week, no replies, i check back a few days later and BAM. And that's only on the part dealing with dimensions. My understanding of dimensions, just became very much clearer.

Parallel Universe, 10 dimensions... Parallel Universes, 10 dimensions and more. This is a theory (more like hypothetical situation really) I came up with the other day as I was thinking about the 10 (or 26) dimensions predicted by string theory as well as antimatter, thermodynamics and the...

Yeah, that seems right to me. Same answer i worked out while i was supposed to paying attention in chemistry lecture!

Do you mean manage to find ONLY a yes/no question(thus expecting only 2 possible answers, viz. yes or no.)? If so, the question posted above is invalid. As the guard would have to give a question which is neither yes/no. Otherwise the above question seems to be the right one to ask.

Chemistry prof Probably not the dumbest, but the funniest thing that springs to mind: While busy with a chemistry prac earlier this year, my experiment wasnt working. We hade cyanide and conc hydrochloric acid which looks the same. I got the 2 mixed up. So my chemistry prof methodically goes...

Hi, I am currently a second year BSc student in South Africa doing physics,chem and math. I've always been interested in space and I am considering going into astrophysics as an career option. I'm just unsure whether there is a demand for astrophysicists around and what the future of...
