Magnetism of a Nuclear Reaction
insane_alien replied to Oddt's topic in Modern and Theoretical Physics
yes, it could well be. overcharging only really applies to two things in physics, capacitors and electrochemical cells. overcharging is when you force more electrons in the negative side than would normally be there for a full charge. this leads to damage of the capacitor or electrochemical cell either by material breakdown or dielectric breakdown. for a current, well over charging just doesn't apply. i'm not even aware of historical usage that would fit with this. -
Magnetism of a Nuclear Reaction
insane_alien replied to Oddt's topic in Modern and Theoretical Physics
are you talking about a pinch? http://en.wikipedia.org/wiki/Z-pinch also what the hell is an overcharged electric current? that doesn't make a whole lot of sense. -
what they do is cover a forum with posts, then later go back and insert the links. however we cleverly avoid this by limiting the time in which posts can be edited(we actually do this for other reasons. namely, people rewrite history if given the opportunity). we also don't let them have signatures either. another common spam vector. interestingly, the absence of these features doesn't seem to cause any errors.

brown-ish implies impurites. check what you're trying to dissolve is actually tin and if it is, how pure it is. also, stannous chloride is easily soluble so it won't form crystals until you evapourate the water

oh no, general relativity does stop anything from going faster than the speed of light, it just sets certain limits on its properties. for instance, it must always have been going faster than light, it will have complex energy and it cannot be made to go slower than the speed of light. to be perfectly accurate, relativity says nothing can accelerate through the speed of light. however, quantum mechanics says that any tachyons would be unstable so that does kind of mean that there are no cool superluminal entities.

hmm, growing the rest of the body to get a specific organ seems wasteful and probably more difficult than just growin the organ

i think first you should read up on basic electronics first. then go read up on magnetohydrodynamics to realise plasma doesn't behave like that.

earths gravity is lopsided so it'd hit the pole anyway even iff angular momentum never came into it

How Biotech may help people live longer in the future
insane_alien replied to nec209's topic in Medical Science
gives it more time to manifest. cancer wasn't such a big problem 200 years ago largely because you'd likely be dead before it became a problem from some other factor. other factors like, regular disease, malnutrition, war/violence etc. etc. now when we regularly live into our 80's and 90's if cancer does appear, you're going to be around long enough for it to become a problem. -
well mass isn't energy moving at twice the speed of light so the weirdness after is moot.

hydrogen chloride is a stronger acide than sodium acetate. the chloride would displace the acetate from the sodium as it would be the prefferable reaction.

you can't. you can only change it from oneform to another.

How does our Galaxy maintain a fixed form?
insane_alien replied to alpha2cen's topic in Astronomy and Cosmology
simple, it doesn't maintain a fixed shape. the reason it appears to is that it is so massive so changes(especially significant changes to its appearance) take millions and millions of years. -
mmm 2 datapoints. if only we could all publish on such a full and complete dataset[/sarcasm] seriously, two datapoints means NOTHING. I have an experiment i'm running at work. I have forty five THOUSAND datapoints so far and i'm waiting on 20000 more before i can safely say whether or not there has been a success or not. (preliminaries look good though, unless the readings take a nose dive and stay there then it should be proof positive) and even this can be considered a scant dataset in some fields. the LHC will gather trillions of datapoints before they say one way or the other on the higgs boson (and even then it might be tentative). relying on 2 isn't good. especially when the data is known to be flawed and seemingly cherry picked.

yeah, they know about it. it doesn't work. also, the global standard is IE7 getting that changed would be like 2 years of justification, testing and modifying for them. the virus protection and firewalls are actually pretty damn good so there isn't realy much reason to move away from it. It's only when you go to access the general web that you get any issues and thats what chrome's good for.
-
I'm ambi-browserous, I use chrome and firefox at home and i use chrome and IE7 at work. at work i need IE7 to access some of the applications on the intranet(they work with chrome but not so well as some numpty seen fit to code them with IE7 specific HTML. they don't even work right with IE8. still better than the one legacy telnet application that gets used once in a blue moon when we need to export something from the ancient system that got forgotten about some time in the early 90's
-
yes as by definition nothing can be outside of the universe.
-
yes there are but the specific parameters used in the GPS satellites are for earth only because earth is the only planet they orbit If they orbited mars then they'd use correction parameters that work on mars and they can be predicted by general relativity. which is the point. general relativity is the source of those correction parameters.
-
no but you could develop a mathematical model of the human brain, input information memories etc. etc. to make the model go into the same state as an organic brain would be in if it was in love and hey presto! a mathematical description of love.
-
that has nothing to do with force being energy. and gravitational waves aren't carried by space-time. they move through space-time but then so does everything else.

Company claims to produce fossil fuels with bacteria
insane_alien replied to Cap'n Refsmmat's topic in Science News
well, i imagine they'll have some form of culture maintenance medium that has to be added to the bioreactors, trace elements, vitamins and such. i don't see them doing it that economically though. the major problems will be in collecting the 'waste' CO2 this is actually a lot harder than most people think on the plus side, their claimed capacity od 25000gallons per acre per year seems reasonable enough. thats equivalent to 25.36W/m^2 which is within the solar constant by a large margin and means about 2.5% efficiency. this is believable. However, because of such low efficiency you'd be better just switching over to electric as solar panels and batteries can exceed 2.5% efficiency. -
So, you created a gravitational formula from einsteins relativity? you realise that is what genral relativity is right? you spreadsheet is pretty unreadable. however it seems you never actually use any of the relativistic equations. in particular, you use the fromula for newtonian momentum, i honestly haven't bothered trying to decipher the rest from the pdf(some parts of that are unreadable as well. not to mention the Wall of Text layout) you seem to be assuming everything has a linear relationship and uses basic mathematical operations. not once did i see any calculus which is essentiall for describing the systems you seem to be attempting to describe. there's a fair bit of handwavium as well. I honestly don't know what you are trying to say or how successful you were in saying it.

Where Are the Coldest and Hotest Spots on Earth?
insane_alien replied to alex sam's topic in Climate Science
magnetic pole shifts take thousands of years. the magnetic poles have little if any effect on surface temperatures. -
most operating systems have a good entropy pool. i think even windows does. why not just pull the seed from there every now and then? its going to be more random than the time which is sequential. if you know the next seed will ALWAYS be higher than the last then it makes it easier to spoof.
