What is the absolute simplest known formula /algorithm which approximates Pi? I don't care how slowly it converges, it just needs to be as simple as possible.

Scientists always fall for the logical positivism meme. And they don't even realize it's a philosophical position with philosophical justifications....
They're pretty dumb to be honest. They have massive tunnel vision and because of that they don't realize their epistemic assumptions and treat the scientific methodology as axiomatic, they think it's common sense. And when someone approaches a problem with a different epistemological framework they think it's bullshit...
They're simply very bad at thinking outside of a scientific framework. Thoughts?

Made and figured out this puzzle in a half hour yesterday, that being said I have oodles of paradox equations so I had my pick of straws.. but emphasizing them in the right conditions is the interesting part
Anyway I went about 4 more depths in to the structure after this had an epiphany about tetrahedrons and had a drink and went to bed
So OP, what do you think of this geometry philosophy?
Also, Science in general is the crypto philosophy of all time, just in mapping the patterns of discovery so far we're due to have an epoch of redistribution of what the priority structures are within the next decade never mind century, we've become to thirsty for the patterns that displace data and we will likely be coercing our governments into creating narrations of these complex structures with, likely, dissected elements of what makes the constitution of other things
If any of you have decided to make one of these on your own then I'd be interested in discussing it with you here.

Hi.
Can electromagnetism be considered a force in itself, distinct from electricity, and magnetism, alone, and more than just the mutual interaction of those two?

Electricity and magnetism are just two different manifestations of the same thing. That's why they can be linked under electromagnetism.
What are the limits of human electrical sensitivity?

Is there a formula to solve this by hand, or do you actually need a graphing calculator for it?
My professor is insisting that a formula was given to us, but I can't find the damn thing in any of my notes.

I have a question about prime numbers that might not have a proven answer, but here it goes.
I'm using the term 'gap' here loosely because I know 'primes gap' is a real term concerning the areas where we haven't established where primes may or may not be.
However, my question is, what is the largest 'gap' possible between every prime?
in other words, if gap = difference, the gap between primes A and B implies that in the range between those numbers there are no primes left, what is the maximum difference between A and B possible?
E.g. there are no primes between 23 & 29, that gap is 6 as 24,25,26,27,28 are not prime
there are no primes between 1327 & 1361
gap is 34
Is there any conventional method or theory for defining the maximum difference?

This gap you described has no bound, meaning that for every natural n there are two primes p,q with p-q>=n so that there is no prime number r with q<r<p.
>>
>>7727321
That literally is the definition of a prime gap, [math]g_n = p_{n+1}-p_n[/math]
That gap increases to infinity. That doesn't mean there's a finite amount of primes, it just means it gets arbitrarily large for high n. Interestingly there's times when there's a huge gap between primes and then there's a twin prime right next to it.

an update to a post from 5 days ago:
I asked this board whether it was possible to cram for Organic Chemistry in 2.5 days 9 (and pass with a decent grade) if I hadn't studied since the midterm and gotten 43% on that exam.
Most said it was impossible or that I might eke out a 50% if I was lucky
You're either all complete idiots or enjoy demotivating people because it's easy as fuck to learn how all the reactions and mechanisms work in two full days of study. Final was easy as fuck. 3 step synthesis problems easy as fuck
anyway good on luck on your lives if you aren't able to do what I just did

Let's talk about medicines that the western world ridicules but is actually useful and effective.
1) Cannabis - I don't think I really need to go in to depth here. The uses are numerous and it's incredibly safe when eaten or vaporized.
2) Colloidal silver - Potent antibiotic. Very safe. Undesired side effect if applied topically and then exposed to the sun - can turn the skin blue. Although this is very rare and easily avoided. Robert Becker demonstrated that if you apply colloidal silver to wounds and pass a small current through the wound, tissue healing is observed and accelerated.
3) Grounding - Multiple studies show benefits for heart health, nervous system, exercise recovery, etc.
4) Alkaline diets - Your body prefers a basic pH. Consuming heavily acidic foods and drinks makes the body work harder and use minerals to re-establish a basic environment. Basic diets can help enhance healing.
5) Master cleanse diet - Not healthy for long term weight loss, but helps facilitate healing in the short term. Fasting or pseudo-fasting helps regenerate white blood cells.
6) Yoga/meditation - Increases mental health and has benefits for your heart, etc.
7) Psilocybin mushrooms - Powerful antidepressant. Triggers growth and regeneration of brain cells.
8) MDMA - Very effective at helping overcome PTSD.
9) LSD - One or two strong doses can help a lifelong alcoholic kick the habit for good.
Any comments on these? Anymore you can think of?

1) Lots of western nations allow cannabis for pain/nausea treatment. It has no other proven uses, really.
2) Antibiotics developed since, I dunno, 1910 are far better and less harmful. Mostly it's alt-med bullshit these days. Passing current through any wound stimulates healing; the silver has nothing to do with it.
3) No.
4) No.
5) No.
6) Perhaps. Or you could end up like my yoga teacher, with a fucked up spine, unable to walk or sit properly. Almost everyone who does yoga regularly ends up with a serious injury from it.
7/8/9) Yes, just ignore the side effects.

Are any of these actually ridiculed by the western world?

Colloidal silver is only considered good by genuinely mentally ill lunatics, of the sort that would come to /sci/ and claim that the world is flat.

Sup /sci/,
I'm just about to graduate with a BS in Biology next week, but still have a thesis to write, and I'm fairly confused.
We're supposed to write a 10 page paper about an experiment conducted in the lab, having done so with a different paper as a reference for the experimental outline, and I doubt I could fill 10 pages. Most scientific papers are less than 10 pages and the experiment we conducted in the lab was fairly simple and straightforward.
What's your experience with undergrad theses? Any advice?

>10 page thesis
WHAT THE FUCK
>>
>>7726772
Well, we're supposed to include graphs from flow cytometry and provide an introduction about the specific chemical that was used to test cytotoxicity, which is basically the whole experiment. Materials and methods, conclusion, etc.
I mean you could easily fill some 5 pages, but 10 is really a stretch and I'm wondering how people do it.

Bump?
Hey /sci/ I wanted to ask this question to either you or /k/ I figure this board makes more sense.
Hypothetically speaking if the U.S. government and all private military industrial corporations and the like tried to produce the maximum amount of tanks, planes, boats and guns just how many could they produce in a day? How about a week? A month? A year? Answering just a day will answer all of these but still.
I'm having a hard time trying to google just how fast the U.S. Government and private corporations can manufacture.

If the relationship is: govt pays while industry manufactures then it would depend on how much the govt is willing to pay. If govt pays enough, industry will respond by creating more manufacturing plants to meet the demand thereby increasing output capability.

Vegetarian and 'healthy' diets could be more harmful to the environment, researchers say

It seems to me like this is just Monsanto propaganda. There is more profit in engineering and producing animal feed than selling plain vegetables.
"Eating lettuce is over three times worse in greenhouse gas emissions than eating bacon"
How could this possibly ever be true?
I live in an area with lots of natural rainfall, and lettuce grows in my yard for 2/3 of the year. But all I ever did was plant seeds and the food just grows out of the ground, raising a pig would be thousands of times more resource intensive

>Higher resource use per calorie
This is not surprising at all. Vegetable crops generally require a lot of water, pesticide and fertiliser to be produced on a large scale, especially when compared to cereals. They also have very little calorific content when compared to meat and cereal crops.
Makes sense they require more fossil fuel energy, and more natural resources per calorie.
>>
>"Eating lettuce is over three times worse in greenhouse gas emissions than eating bacon"
>How could this possibly ever be true?
Did you try reading the research that they reference?
>>
because of the high amout of calories in bacon compared to lettuce you would need a lot more lettuce to get the same amount of calories.
But the thing is you wouldn't really eat all lettuce for your calories, you would supply with bread or something else high in carbs to get enough calories. Can't seem to find the original research though. I'm just lazy maybe
