Is graph theory nice?

Depends what you mean by nice and what kind of graph theory. You use it for all kind of physical, topological, algebraical or stochastical problems (for example Markov Chains, Random walks on graphs etc). If you like to work with combinatorial tools and matrices. Yes why not?

Yeah I like it, download neo4j, graphs look nice.

please no roleplay Christians or baiting

what exactly is wrong with the theory that a divine being created the universe and mankind in its own image? Is the development of human consciousness itself not proof of the existence of the divine? How else could you account for human beings having seemingly having deific powers of the mind in quality and scope if the divine itself does not exist? No other creatures have consciousness and as a Christians I believe human beings being given a divine personality or personhood atttached to a mortal coil this external shell is proof in and of itself of miracles. What's wrong with this proof?

And yes, this doesn't necessarily support only a Christian God but it does account for the existence of divinity and explains consciousness which evolutionary scientists can't explain. It seems really childish in the absence of any other explanations to dismiss our view of the nature of man as "hurr durr all religion is retarded". Not baiting but if you have atheistic stubbornness you should really try lsd or psilocybin because being hostile to anything that contradicts your worldview isn't a good virtue.

to expand a bit on the arguement in OP, it's having this physical form that I think hides the true nature of man from most people. When I talk to people about this they seem to feel kinship with animals, they just see themselves as being more advanced cattle. I'd like you to take a minute to just think of human consciousness and what it really is, and realise what we are in relation to cows or chickens. They're nothing compared to us. They're a collection of instincts, emotions and senses.

No the more we "advance" the more complicated our society becomes and we make more mistakes. These mistakes will culminate in the destruction of society as we know it, leading the people who would have been researchers to die or become farmers/hunters/scavengers instead.

What do you mean by conjugate to magnetism? Your picture only depicts the field lines and potential lines. Moreover, this example you show is a static dipole field. There is no magnetism present in a static dipole field. (Would need permanent magnets or large scale charge flow.)

Since /fit/ is completely retarded and doesn't know anything about it, can someone here enlighten me? I guess it would be something like ottermode but of course I might be wrong. As for workout is cardio really the best thing about it or one should also do workouts that focus on bodybuilding since that increases test and thats extremely important, its seems. Please elaborate as much as possible.

the most important fitness indicators are resting heart rate and body fat percentage.. so do cardio and don't eat like a piglet. also people with higher muscle mass have an easier time reducing their body fat, so strength training is good too. /fit/ people are mostly concerned with getting big which isn't bad in and of itself, but you can't neglect training cardio if you actually want to be healthy.

Weights for endorphins = good times for your brain. Cardio for blood flow and further endorphins. Low bodyfat for lack of depression which fucks with your brain. Vitamins all accounted for otherwise your energy will suffer. About 8 hours good sleep in a completely dark room to get the benefits of that.

Holy shit.
Is fusion finished at this point?
There's literally 0% chance that it will ever be cheaper than fission, let alone other power sources.

Should we divert all energy research funds to new fission ideas like molten salt reactors instead?

That's lockheed martin, they're trying a design that's already been tried. It failed before, no surprise if it fails again.

Lockheed's fusion effort is just a publicity stunt.
>>There's literally 0% chance
show your math ass hole

>>Should we divert all energy research funds to new fission ideas like molten salt reactors instead?
No. If you diverted fusion funding for MSRs you'd barely have any funding at all.

I will say this though, clean coal and carbon capture research are a waste. Clean coal is a scam designed to extend the life of an energy source that should have been killed decades ago. Carbon capture ends up being more expensive than nuclear because of the thermodynamics of removing carbon. If we're gonna divert money to fucking crazy nuclear plant designs it should be from that.

So I was flicking though this thread >>8992570 and some of the posts were pretty dire. It looks like the majority of people in that thread don't understand how science functions, nor how it [math] can [/math] function. In particular there seems to be a common theme running thought it that you need evidence that something doesn't exist. Now to my mind that doesn't make sense since how can something that doesn't exist ever leave behind evidence that it was never there.

Is it time to start teaching philosophy to children? I can't really see any other way of getting away from the ideas in that thread.

Pic unrelated...Well maybe not that unrelated.

You can't know if something was 'never' there, but you can know if something is not there currently, simply by something else being there

but absence of evidence isn't evidence of absence
>>
>>8995927
Instead of trotting out your ebbin Carl Sagon maymay, why not engage with the argument? What would the evidence of something not existing look like? I mean if it doesn't exist, how can it interact with the universe to leave evidence?

I'm learning Fortran, and it seems like a comfy language. People have been telling me that there's typically only one way to do a given thing in Fortran, which leaves little room for doing stuff wrong, and I think I'm starting to see what they mean.

Anyone else here like Fortran?

And btw, ow do I use LAPACK? I don't know much about programming to be honest besides syntax. Before now I've been writing in Python using Spyder, which literally just werks. I didn't need to mess around with SciPy or anything, just install Spyder and "import" everything. So how do I "install" LAPACK? And how do I get the BLAS? Do I just download some files and place them in the right folder, then continue using gfortran to compile?

Hopefully this is a good place to ask. I tried asking in a programming thread in /g/ as well, but the conversation was headed in another direction.

>>8995805
The weight of the air above presses on the air below, making the air below more dense. Air is 14 PSI because if you took a column of air one square inch all the way up to space, it would weigh 14 pounds. If you're on a mountain, there's less air above you because you're closer to space.
>>
>>8995805
because the concavity of the earth holds the air like a bowl, and any air above the rim of the earth spills out
