I'm not a scientist but I'm fascinated with Mars. Recently I was thinking of the issue of terraforming Mars, that even if we dumped millions of tons of CO2 into the atmosphere we would still have to deal with radiation and losing that atmosphere to space because it has a very weak magnetic field.
What I was thinking was if would be possible to have a bunch of satallites with strong magnets inside orbit the planet to simulate one? Would this actually work or is it too expensive? Or maybe I'm making assumptions about magnets that are wrong.
>>7781766 The biggest false assumption you make of magnets is their strength over distances. The strength of a magnetic field due to a magnetic charge is inversely proportional to the distance from the charge squared (r^-2). Not to mention even if you got strong enough magnetic charges, on these satellites, you could never keep them in orbit. Also, this wouldn't create anything even remotely similar characteristically to the magnetic field that our planet has.

In terms of pixels, that's an exceedingly large image for a periodic table which contains relatively little information and is significantly out of date.
Not chem here (math) but it's kind of cool that the seventh row will have everything completely and officially named by the time you start studying, anon. I can remember a time when "unununium" (nice word) was common.
Is smoking being ridiculously bad for you just popscience? /sci/ is supposed to be for smart people but they insist that secondhand smoke is bad when it clearly isn't, especially when smoking in itself is incorrectly linked with many health problems caused by other factors.
Why do people, especially supposedly smart people, buy into this? Most smokers can suffer a small number of health problems... Comment too long. Click here to view the full text.
Why did retarded mathematicians invent something as stupid as limits? This is the most amibguous shit I have ever been forced to learn. Even when trying to PROVE that a limit for a certain series exists, the proof just suddenly stops and q.e.d. Then you just whatever the fuck you want for your inputs and you're done. Circulatory logic at its finest. If only maths were the domain of engineering, then everything would have nice and clean order. Thanks for nothing, math-FAGS!
As I understand it (please do correct me if I'm wrong) at each moment of time the universe's ground state of energy fluctuates in multiple different ways which is the fundamental basis for nature as we know it.
However are these fluctuations deterministic? Why do certain actions with that ground state happen when they do? Is that something we're still trying to understand or am I just completely misrepresenting the issue?
It's all a long deterministic chain reaction that started (presumably) with the big bang. Everything after that is a result of action-reaction transfer of energy, which is based on completely physical, deterministic laws dictated by mathematical rules. That's all there is.
>>7781450 I assume you're talking about vacuum fluctuation. This isn't actually a time-dependant fluctuation - the ground state does not change over time. Vacuum fluctuation means that if you were to measure the magnetic field, say, of the vacuum, you'd find that the result is not zero, but oscillates around zero. This is essentially the same as Heisenberg uncertainty, but in field theory,
No, the structure has very little to do with it. It has more to do with how dense you can make your jaw when you receive the impact. Which is why mouthguards are a really good thing. But in the end it doesn't matter what you do, if you're getting hit by a force strong enough to knock you out you're going down no matter what.
Anyone know anything about bioinformatics/computational biology? I might get a research gig this summer in it but I'm debating whether it's worth learning Perl. Is it alright for someone who otherwise hates biology?
>>7781393 monitoring thread. I've asked /g/ and /sci/ the same question and no good answer. Just looking for a good place to start like a textbook. I don't know anything about programming either but have a bs in microbio.
>>7781399 >>7781577 There were several textbooks on computational biophysics recommended in the textbook thread, other than the ones posted on the wiki. But since you're being such a little bitch about it I'm not going to repost it, go find it in the catalog yourself.
>>7781393 Asking whether to learn Perl or not is such a stupid fucking question. It's completely irrelevant, ask the research group you want... Comment too long. Click here to view the full text.
