Look at pic related which is the current entry in the Particle Data Group publication. (PDG is the source of record record for all things particle physics, not webinars broadcast from CERN.) You can look at the other particle data entries for the other fundamental particles (http://pdg.lbl.gov/#) and you won't see any of this roundabout language about what the particle is labeled or called. Five years later, PDG still won't touch CERN's claim that they found the Higgs boson. The particle almost certainly has spin-1, in agreement with my prediction (http://vixra.org/abs/1302.0037) and if so it proves that I am in fact the world's greatest living physicist, but the crotchety old cowardly cunts who pretend to that title don't want to admit that someone so unlike them is so vastly superior to them in intellectual affairs. >> >>8863326 >BREAKING: The Higgs is amazing! >>8863352 >A final determination of the spin of the particle would one thing that normally would have been reported. https://arxiv.org/pdf/1307.1432.pdf Not suited for mass media obviously. >> File: Capture.png (287 KB, 837x376) 287 KB PNG >>8863369 I hope you are not so feeble minded that you think this paper reports the spin of the particle. They compare spin-0 to a few decay channels, but to make a final determination they need to compare the data to ALL LORENTZ INVARIANT amplitudes for [math] H^0\to\gamma+\gamma$ not just a few of them. There are only about two dozen such amplitudes (https://arxiv.org/abs/1211.2288) and they still have not published the results of the only analysis that matters: how the data stacks up against all possible spin-parity configurations. It is absolutely outrageous that

1)they have not published this analysis in the five years since they found the particle

2)no one is calling bullshit on this outrageous abortion of science

This analysis is completely easy to compute, they have had sufficient data to do it for years, yet they do not.

If you guys are so smart why arent you in the most difficulty field of all cognitive science. Little boy and his mathematics. IT's not even like you understand thats just a non responsive language.

Cognitive science is just an umbrella term for the direction some researchers in linguistics, psychology, AI, neuroscience and philosophy (and some might say anthropology, but this is less true now) take. All these fields can be understood as trying to model cognition in some way or another. I don't know what your field of study is, but neuroscience by itself says very little about cognition. This is why research in cognitive neuroscience is always going to be very interdisciplinary, especially with psychology. There's not trying to investigate cognition through neuroscience without relying on higher-level psychological models of cognition. What you seem to advocate is a purely reductionist methodology for cognitive science which, if you worked in the field, you would know is utterly useless.

Drink cups of broth when you're hungry. It takes the edge off, and also gratifies 'want food'. I myself /still/ find it difficult though, after a day you may not be hungry but you have a sense of lack, related to food. It's hard to explain. It's good to be distracted by, eg, work if you can.
>>
>>8860455

This would explain why when you eat after you're hungry you feel extremely tired. It's cause your brain is overlocking its gpu and when you finally eat that survival mechanism/ boost in cognition dissipates.

Bill Nye: I'm a scientist

>>8863360
Yeah, well that's the whole point in their argument
They're effectively re-defining gender to be different from sex, since sex is biological (there's no arguing that), but they are wanting to claim gender is more social based, like what I said about how you identify, rather than your biological sex.

If they were smart, they'd ditch the whole word gender altogether and just come up with a new one which means exactly the same thing, but isn't redefining a word, that way no one can argue with it.
>>
>>8863368

>>8863368
I agree completely anon. It seems the definition of gender is personality but anyone can make one up to describe themselves. And with pronouns, we should just use them in accordabce with sex as that is easy to tell and doesnt require people to remember made up words

I want to go into artificial intelligence but I don't have money for college.
What are some good textbooks/channels/free online courses/Internet forums I can use?

The only problem though is I fear ai may be too complicated for any one person. It would require knowledge of programming, discrete mathematics, and electrical engineering at the minimal.
Networking is needed to communicate with other ai, Internet, etc.
neuroscience and biology/bioengineering background would be extremely helpful
And knowledge of psychology and sociology would be needed to refine it

That's a lot of material, so also what are some suggestions as to how to get into this social niche?

You've got two decks of cards. Each consists of numbers from 1 to 20. After you mixed all, you deal them out to two people. What's the probability that one person has at least one 1.
>>
>>8863327
Fuck you are right I got what you mean now.

It should be P(A or B) + P(A and B)

Fuck I'm done with this shit
>>
>>8863327
wait fuck me,
P(only first 1) + P(only second 1) + P(first and second 1) = (2/40)*(38/39) + (38/40)*(2/39) + (2/40)*(1/39)

>>
>>8863341
>>8863289
Previously I did not take into account card replacement and the chance of both happening

A = First person getting a 1
B = Second person getting a 1
B depends on A
Both are not mutually exclusive

So...
P(A or B) + P(A and B) =
P(A) + P(B) - P(AnB) + P(A) * P(B/A)
P(A) + P(B) - P(A) * P(B/A) + P(A) * P(B/A) =
P(A) + P(B) = 2/40 + 2/39 = (78+80) / 1560 = 0.1012820513
Or
10% probability lel

I'm not sure this is correct.

You understand how unlikely it is for things to fossilize, right? And then how unlikely it is that we'll happen to stumble upon it later on, yeah? That is why there are "gaps". Because fossilization is uncommon.

Assuming you are not bound by any physical laws, design a space that has the following three properties:
>travelling between two randomly chosen points always takes a finite time
>it can fit an infinite number of 3D objects inside
>it is realistically possible for normal three-dimensional interactions to occur (so you can't just say "just have 4D space" because attempting normal 3D interaction would be like holding two infinitely-thin pieces of paper and having them touch edges)
>>
>>8863120
>Any two points must have a path between them that is finite in length.

Hmm, can length ever be truely finite though? I mean, if you can continuely add percision to the measurement when you look closer, is it technically a kind of infinity?
>>
>>8863210
>Hmm, can length ever be truely finite though?
Yes.
Both in a mathematical sense and a real world sense.

> I mean, if you can continuely add percision to the measurement when you look closer, is it technically a kind of infinity?
No. Something finite can be made out of infinitely many parts, at least in mathematics.
In reality everything has to be finite.
>>
>>8862867
Every Lorentzian 4-mfld satisfies the above.
>>
>>8863120
im assuming you want length defined by the metric, but how about volume? do we have to define that with a sigma-algebras over the metric space?

if there are no constraints, just use normal euclidean space with normal volume and define the discrete metric. then volume is infinite and all distances are equal to 1, thus finite, and 3 is automaticly satisfied
>>
>>8863399
also I assumed you want a space where the distance is bounded by some number M, otherwise this whole thing is retarded and almost any space will work.
