Everyone knows about the butterfly effect, but I've never seen anyone notice quite how powerful it is, so I thought I'd post it here.
Here is how strong it is: Every single decision you've ever made has determined which people were born thereafter, how every sporting event transpired, every 4chan get, and probably every other known fact about the world.
You only need to accept two claims to get this:
1. Small differences magnify.
If you take a second longer to cum in your girlfriend, a different sperm will get through. If Chapman takes a second longer to throw a pitch, he might throw a home run, and the cubs might not win the world series. Any small change in your life will inevitably get magnified into a large one.
2. Small differences spread exponentially.
Suppose you sleep in for one extra second before work. Your life is now slightly different. You will greet your boss one second later, and so his life will also be slightly different. And every person your boss interacts with will also have a slightly different life. This slight difference will spread exponentially throughout the population, soon infecting every human on earth.
Accepting these two facts, it becomes clear that every decision you make causes a slight difference to ripple throughout humanity, which will become magnified into a large difference every time someone impregnates a chick or throws a pitch. So every decision you makes completely rewrites future history.
If I'd made this post a week ago, then the Cubs might not have won the world series.

Yes. This makes me indecisive. Which I don't really think is a good thing... I'm open for debate, though

Your actions integrate with billions of other small and big factors that shape the events around us. So whatever action you do is just a random number in an astronomic clusterfuck of an equation. There's literally no technology available to calculate these outcomes.
Even if we are pre-determined it's impossible for any machine to run such simulation.
>>
>>8453459
In case it wasn't clear, I'm not saying that every decision is the SOLE cause of every future outcome. It's just one of the trillion other causes.
This can be explained by a marketing idea of mine: Say Mountain Dew is deciding whether to release a new flavour, either blueberry or grape. They could put a button online that anyone could press, and then choose which flavour to release depending on whether the button was clicked an even or odd number of times.
Every single person who clicked the button could think "If I hadn't clicked the button, then there would be grape flavoured Mountain Dew in my fridge instead of blueberry." Every single person could think this, even though no person is the sole cause of Mountain Dew's decision.

So I was curious and decide to weight my Ritalin perscription. The script says "10mg" so I assume each is 10mg. So I place 1 on a scale and the scale reads "0.1" when set to grams. Now if it really weighed 10mg, then shouldn't 1 pill not even read on the scale since 1g=1000mg?
Tl;dr does the weight on a pill/capsule represent the full weight of the pill/capsule, or is that weight correlate to the amount of that substance in the pill/capsule?

you weigh the chemikillz.
so if it says 0.1 chemikillz that means you have a 10% chance of dying if you take it.
0.1 times 100%
>>
>>8453413
now before I address you as retardo deluxe, I will say that the 10 mg refers to the active compound in the pill, in this case Methyl phenyl(piperidin-2-yl)acetate, the rest of the weight are excipients
now I'm no chemist, so a more knowledgeable nerd please feel free to correct me

Physicists demonstrate existence of new subatomic structure

Iowa State University researchers have helped demonstrate the existence of a subatomic structure once thought unlikely to exist.
James Vary, a professor of physics and astronomy, and Andrey Shirokov, a visiting scientist, together with an international team, used sophisticated supercomputer simulations to show the quasi-stable existence of a tetraneutron, a structure comprised of four neutrons (subatomic particles with no charge).
The new finding was published in Physical Review Letters, a publication of the American Physical Society, on October 28.
On their own, neutrons are very unstable and will convert into protons—positively charged subatomic particles—after ten minutes. Groups of two or three neutrons do not form a stable structure, but the new simulations in this research demonstrate that four neutrons together can form a resonance, a structure stable for a period of time before decaying.
For the tetraneutron, this lifetime is only 5×10^(-22) seconds (a tiny fraction of a billionth of a nanosecond). Though this time seems very short, it is long enough to study, and provides a new avenue for exploring the strong forces between neutrons.
"This opens up a whole new line of research," Vary said. "Studying the tetraneutron will help us understand interneutron forces including previously unexplored features of the unstable two-neutron and three-neutron systems."
The advanced simulations demonstrating the tetraneutron corroborate the first observational evidence of the tetraneutron earlier this year in an experiment performed at the RIKEN Radioactive Ion Beam Factory (RIBF), in Saitama, Japan. The tetraneutron structure has been sought for 40 years with little evidence supporting its existence, until now. The properties predicted by the calculations in the simulations were consistent with the observed properties from the experiment in Japan.

The research in Japan used a beam of Helium-8, Helium with 4 extra neutrons, colliding with a regular Helium-4 atom. The collision breaks up the Helium-8 into another Helium-4 and a tetraneutron in its brief resonance state, before it, too, breaks apart, forming four lone neutrons.
"We know that additional experiments with state-of-the-art facilities are in preparation with the goal to get precise characteristics of the tetraneutron," Vary said. "We are providing our state-of-the-art predictions to help guide these experiments."
The existence of the tetraneutron, once confirmed and refined, will add an interesting new entry and gap to the chart of nuclides, a graph representing all known nuclei and their isotopes, or nuclei with a different number of neutrons. Similar to the periodic table, which organizes the chemical behavior of elements, the nuclide chart represents the radioactive behavior of elements and their isotopes. While most nuclei add or subtract neutrons one at a time, this research shows that a neutron itself will have a gap between a single neutron and a tetraneutron.
The only other known neutron structure is a neutron star, small but dense stars thought to be made almost entirely of neutrons. These stars may be only about seven miles in radius but have a mass similar to that of our sun. Neutron stars have neutrons on the order 10^57. Further research may explore if there are other numbers of neutrons that form a stable resonance along the path to reaching the size of a neutron star.

My professor of the theoretical mechanics lecture just told me to read this book if i find the time to do so. is it any good?
He said it's pop-science and won't help me solve problems but still explains scientific (and also math??) concepts beautifully.

I know this isn't directly related to math and science, but one of my professors asked me if I was doing undergraduate research and talked to me as if he expects me to do it before I graduate.
so, as a math student, what does undergraduate research entail and how do I get into it?

Where are you studying where they expect you to be making undergraduate research? And are you sure there was no miscommunication and the prof actually meant if you're studying something on your own?

I go to a shitty state uni, but he was talking specifically about a grant for undergraduate researchers, and when I told him I wasn't doing it, he replied with "not yet, huh?"
I hadn't really considered it because I didn't think I was cut out for it, but his comment sparked my interest in it

How do I become an engineer and what are some career opportunities?
I was thinking of getting into it. I've been reviewing Arithmetic with Khan Academy to prepare myself for reacquainting myself with Algebra and the rest.
I'm going to order University Physics with Modern Physics (13th Edition) & Precalculus Mathematics in a Nutshell: Geometry, Algebra, Trigonometry at one point, after I've finished all of the math courses on Khan one or two times.
I was thinking of getting into either aeronautic engineering or, forgive my meme-tastic ambitions, robotics.
But I don't know what to do after I've taken the course(there is a two year course at a technology college in Calgary). What kind of jobs could I get? I'm assuming all the prestigious and fun jobs are reserved for old farts and richkids who buy their way to the top.
Also, any recommendations for what type of math and other concepts I should be focusing on is really appreciated.

If you're serious about either of those fields, you'd better get start getting cozy with tensors, indicial notation, matrix math and vectors.

Let me explain: The "Fringe" got me into this shit and it's also what lead me back to our Creator. I had an astral "encounter" for about 15 seconds and it scared the holy living fuck out of me, but you know what? It woke me the hell up! Maybe it was my doing on "the other side" and my plan all along (I do LOVE some good shock-n-awe), but at this point I don't care if it was some PSYOPS something or another. It worked, EVEN IF it was bogus. I've never experienced anything while awake, although I used to have what I considered a "reoccurring dream" when I was little of an tiny alien spaceship keeping tabs on me while I played outside. Possibly not a dream at all, BUT still don't care. See, all this sparkly bullshit about aliens, UFOs, spirits, and what-have-you isn't the REAL agenda here. Going within and finding YOUR truth IS. Now, I still have an affinity for the wild and crazy because that's just who I am and always have been, but I've had ideas presented within a "symbolic" system and they feel nothing but millennia old to me. Could I be a victim of governmental bullshit? Well, I suppose, but then that would seem to make me waaaaaay more important than a 40 year old Southern woman. And if I'm THAT important to target.......then I'd have to believe I would pose a threat to someone pretty high-up, seriously......that's fucking flattering as hell. I could only hope to be able to scare the shit out of some controlling fuck to the point to where they felt like "having me meet a grey" would scare me off into a cave somewhere. Well, I have news for them.....this shit backfired in their face, because I AM that I AM now and there's NO stopping dis bitch until I've discipled the shit out of some Christ Conciseness. There is A LOT of truth and disinformation out there and honestly, it ALL leads home eventually. Take the long way or the short way, but just fucking get there! <3

OP here. Each sequence.
Hi /sci/,
I'm not sure whether there are any linguists around here but i suppose this is the most appropriate board.
I don't understand this analysis. Can someone explain?
Why is the possessor assumed to be an internal argument? I thought internal argument meant the argument that is merged to the right of the head... surely the possessor is merged to the left and would thus be the specifier/external argument?
the way i understand it the whole analysis rests on the assumption that the possessor is the internal argument, am i wrong?
also, i can't follow the conclusions.. what exactly is this even supposed to prove?
i'm not well-versed in this kind of syntactic theory and in fact do not believe in most of it but i really need to understand this paper...

I am a college sophomore, So by the time the exam rolls around I'll be through linear algebra and diff eq. Is this level enough?
