Anyone? I haven't made any progress so far.

you can probably approximate it with some normal distribution for high enough n

>>8120218
Well, I've generated it numericaly and it's nowhere like normal distribution. More like two exponents mirrored and glued together with peak value in the middle.

A baryon with composition (uuu) is called [math]\Delta^{++}[/math], and it has a mass 30% higher than the proton. Hence going from proton to delta++ costs a lot of energy.

[math]\Delta^{++}[/math] commonly decays into a proton and pion though.
https://en.wikipedia.org/wiki/Delta_baryon

>>8119686
[math]\Delta^{++}[/math] also has [math]J=3/2[/math]. Is it not possible for a [math]J=1/2[/math] (uuu) state to exist, which would be lighter?

>>8119700
Considering just the spin, a 1/2 and 3/2 state are possible, but when adding in the orbital angular momentum, there's no way to maintain that 1/2 state. I don't feel like doing the math right now.

No, the lighter state does not exist.

I did a quick calculation and found that with the amount of energy it would take to convert a mole of protons to delta++'s, you could get 37,000 kg of matter to escape velocity on earth.

You need an accelerator to make these particles.

It's fucking craz, they have created the "god particle"

Everyone knows that Aliens "fallen gods" created the human race for the purpose of a working slave species to mine gold since the beginning of our history. Gold is the best conductor and resource for them. Think of kings and rulers, why were they all so obsessed with gold? "The gold is for the gods"
This is a more advanced portal for them transfer things they need to different "dimensions."
>or there is no telling what is coming in and out.

They want to keep their slaves ignorant to what is really going on. Focused on money, believing we have to live a certain way to survive-therefore feeding the system.

Holy fucking shit

I thought they were just trying to break apart an atom,
Create a black hole.

>Kinda curious what actually occurs
You go to some bombed out shithole and live in a hospital for 2 months, working to stitch the civilians and soldiers back together all the time in addition to vanilla healthcare like deliveries, infections and so on.

It's a workaholic vacation.

You get an ATGM to the face.

Do doctors get IED'd?

Bumping your thread to ask for a babby-tier neuroscience book.

>tfw try to study a bit on my own
>realize I don't know/remember enough basic bio/chem to gain full understanding of basics

;_;

>>8119398
Start by learning some basic bio/chem then.

>>8119402
Well what are some good books for that?
I heard about Campbell Biology being very good for basics in Bio (unless someone recommends something else). What about chem?

Because we decided they are.

In a world where grey is a rare colour and only expensive materials have it, it would count as an attractive/beautiful colour.

>>8119296
Grey is not rare you idiot. What are fucking rocks, what is granite, what colour are almost all pyrolitic compounds (stuff left over after burning). You're statement is dumb

>>8119271

They want to be friendly so you stick around for longer

Is it really that hard to see that

I support the glorification of simple, menial tasks as complex intellectual problems. As an autist it increases my social status and sexual fitness.

Not really comfortable with normal sexual situations, though, so I'm really hoping this promotes some more autism-compatible sexual activities.

>>8119120
People like getting pat on the back for something they've already accomplished and it's that simple. The fact is that the MIT article is worded to come across as "If you've beaten Super Mario, you're practically a mathematician" rather than comparing the two or simply saying "Super Mario is of comparable difficulty to some complex math, if you've done the former you could probably do the latter". That alone says a lot about the public attitude towards math, the public attitude against learning, and how desperate higher education institutions are for free publicity.

What exactly constitutes autism-compatible sex, being embraced by a non-sentient non-threatening electronic body pillow with a synthetic vagina?

Life was 100% destined to happen mathmatically, and, depending on the existence of a real "free will", possibly beyond.

Let me use an example:

I have a billards table and on that table I have 23 billard balls. If I hit one ball (assuming no one reaches over and interferres) it will bounce off
of other balls, which will bounce off others, and so on. If I sat down and knew the exact physical properties of the environment, the balls, the force
in which the initial ball moved, etc. etc. I could, with enough time and energy, calculate exactly where the balls would end up at any given moment, which
balls would hit which, hard hard they would hit, and eventually even the end. I could, in fact, calculate the future as long as I hit the initial ball EXACTLY
the way I calculated for. The rest, after that, would not be random.

Multiply that... keep multiplying until you give up and then some more, you now have the ability to calculate from the moment the Big Bang happened until life
presented itself. Each atom bouncing around, colliding, merging, breaking, etc as physics would have dictated, eventually forming larger objects that physics
would dictate and the movements and collisions that came with that. On and on. Because each was not random nor had any capability of being random. Each performed
exactly the way it would be expected.

Why life and WHAT life?

Because, assuming that any form of life has any real ability to act randomly, EVER, you could no longer calculate 100% accurately. This is not saying that any life
does, but until something that is really random enters the scene you could, in theory, calculate infinitely and determine the outcomes. As long as you could
calculate before hand or faster than the events. If no form of life can act randomly (what I will call "free will") you could calculate on and on until "the end".

At this moment, Earth life would be the 100% meaning of life. As we have no knowledge of any life anywhere else. If new life is discovered, depending on if it
had any effect on Earth life or not before Earth life came to be, Earth life would still be included. If another life form had ANY hand in Earth life coming to be
then Earth life could very well NOT be included in this 100% group. Of course, if life does not possess any ability to be truly random, it matters not what life nor
when.

So far, I hope you are with me.

If anything in this universe has the power, at the moment, to behave randomly it would be life. I am not saying it can, but if it can... just once.. that one point
becomes the point in which 100% ceases to exist.

With that out of the way, I MUST touch on the bigger question. If nothing from the point of the beginning until the emergence of life, or after, was random then it
makes sense that the beginning would not have been random. It is hard to imagine that one random event would create nothing but order on such a massive scale for such
a massive time.

IF Life can be truly random:

I am using this a lot, I know. I use this because, despite what we know, we BELIEVE life can act outside of predictability. We WANT life to have just one kernel of
governence over its actions that is not pre-determined. Who am I to say NO? If we do then we are more special than anything that can ever be created. We have a "soul"
of sorts that allows us to behave in ways unpredictable by anything else. With that comes a purpose. Not for us, perhaps, but a purpose. An event that was destined to
create randomness from pure order would not be an event to take lightly, and could have very possibly happened for that exact reason. (Yes, I am touching on
a creator or creators, etc. and I will at other points in this.) We could be mere scientific observations, exist to populate a multiverse (something that would not exist
without randomness), simply be a dimensional random number generator.

IF Life can not be random:

So far, as far as my knowledge goes, nothing is random. We act in a way that is predictable if you take in account all of the existing variables. Therefore, I was
destined to write this. Which means we follow the rules set forth by our universe, we can accomplish our same thoughts and feelings, observations and behaviors
with extremely advanced AI. Which is pretty much what we are. This would go a long way in showing that we are perhaps a simulation, perhaps for an advanced being
that simply wants to play with something. Life could be just the next building block on the way to randomness, or a purpose, first the big bang... then life... then
[insert next step here] and so on until the purpose is achieved. The same way in which we build circuits to build devices to build software to build AI. We do as
expected and eventually we will have the desired results.

Everyone look out guys, OP's been asked to "work".

>>8119017
>being autistic is called working.

What about it?
Just get used to it, we had to fucking do brainless euclides algorithm when doing diofantique equations in our head.

Neural networks fall inside a family of algorithms and techniques called machine learning. There is also a more recent subset of algorithms and techniques called deep learning that focuses on a class of algorithms known as deep neural networks.

Machine learning in general is a topic that lives at the intersection of artificial intelligence and data science (depending on who you ask they will classify it as one or the other).

It may be useful to you to learn some basic machine learning but it is probably more useful to get acquainted with AI in general.

I recommend you use those free online courses first to get a general overview and then pursue it further if you find it interesting or useful.

Andrew Ng used to teach a machine learning course at Stanford. There was a theoretical mathy version and an applied engineering version of the course. Back in 2011 he taught the engineering version online and shortly afterward he founded coursera with that course available. It is still available and in my opinion the best introduction to the topic out there.
The Udacity guys also started at Stanford at around the same time and their first course was an intro to artificial intelligence. It is also still available and gives a good general overview to the ideas, techniques, and concepts of artificial intelligence.

As for deep learning. Don't worry about it for now. Basically it's machine learning on steroids and it's at the bleeding edge of the cutting edge. Look into it if you find machine learning interesting or useful.

Robots have little to do with neural nets.
Unless you're working on something weird, like a mail sorter.

But go ahead. It's fun an relatively simple.

i think in robotics they have been using a lot of temporal difference learning which is part of reinforcement learning. if im not mistaken this is how the atlas robot from Boston dynamic robot learned to walk. (educated guess) there might be much more ways also using neural networks or combinations.

Matter comes from the soil and the atmosphere, energy comes from the sun or geothermal vents

wtf. they take nutrients from their surroundings.

Other cells

Depends if dragons can be used to forge the statute.

Bronze Age Greeks did it in real life.

No they did not.

I believe a successful one was carried out 9 months before you were born anon...

It's a term used by creationists to create a mental barrier in the sciences that evolution can't cross.
Basically: "We can't know what happened millions of years ago, so we'll use this book to tell us how it was. You don't have to worry about evolution, that doesn't apply to anything, you can throw it out."
Or: "it's your way or God's way."

>>8118624
It's the creationist way of saying "you weren't there so you can't know it's true" which applies to, as just one example, carbon dating. However, the bible is still infallible. It's pretty logical.
