comment Do multiple permanent magnets aggregated together approach the same strength as a single magnet of the same size?
@Matt: I submitted an edit to hopefully try to clarify.

Provided an answer below -- may be for others to judge if this is really a physical answer or an engineering one.

comment Doubts about tubular Feynman diagrams in string theory
I'm a little confused here, do you mean "tubular"? Or is "tubunal" just a term I'm not familiar with? Thx.

comment What objective criteria distinguish between valid science, fringe science and pseudoscience in physics?
Development of scientific ideas often takes much longer than the discovery. Not everything happens as fast as the Manhattan Project or the moon landing. It took thousands of years for the knowledge of the spherical Earth to have practical applications...

comment What future technologies does particle physics and string theory promise?
@KeenanPepper - I don't know so much about "impossible to predict" so much as "very difficult to predict". Or, to be precise: It may be that the scientists who study these phenomena may not be the best people to predict their applications. This may be due to their training, their mindset, their unique viewpoint, who can say? But there are two classes of people that don't do horribly when it comes to prediction: science fiction authors, and inventors.

comment What future technologies does particle physics and string theory promise?
Respectfully, @LuboŇ°, you're not answering the question. You may be correct but correctness is not a sufficient condition for a good answer :) I view the question as a thought-experiment: if particle physics and string theory lead to technological advances, what could those advances be?

comment How strong of magnetic field would noticibly attract a person?
Hi Georg - I was referring to the initial questioner's "There is Iron in blood. Iron is magnetic" and pointing out that the effect from this is negligible. I do admit to a simplification :) We both agree that the iron in the body's heme complexes contributes nothing to its overall magnetism.

comment How strong of magnetic field would noticibly attract a person?
To clarify, this is not due to the small amount iron in our body, but rather due to the large amount of water.

comment What's the difference between gas and plasma?
@MartinBeckett Actually, referring to magnetization states or liquid crystal phases as "states of matter" isn't that uncommon. Wikipedia en.wikipedia.org/wiki/State_of_matter has quite a good article on this. It really depends on how broad or precise you want your terms to be.
