How bad can disorders like ocd and anxiety harm your intellectual development??

Are there any studies on this sort of thing?

Depends on the severity. Mild OCD can actually help

Have u searched for the studies... or did u really immediately ask 4chan instead of google scholar.

>>9115560
anecdotal evidence but I have pretty bad OCD and dropped out of both math and med school as a result. also in periods where I'm stressed out, I get retarded. can't focus on anything, brain fog etc. It's pretty shit

In the flop, having in your hands 72 and on the table 89J, which is the probability to have a straight in the river?show how to calculate it

How many people are you playing against?

>>9115532
it doesnt matter. You dont know other peoples cards.
>>
>>9115524
There are only two ways to get a straight.

Either you need exactly 5 6 on the turn and river or a 10 on either the turn or the river.

5 6 (Using AND probability):
% = 8/47 * 4/46 * 100% = 1.48%

10 (Using OR probability):
% = [1 - (43/47 * 43/46)] * 100% = 16.30%

Does anyone know this feel?

Everyone knows this feel. It's common. The fact that you get a good grasp on the general ideas fast is more important.

>>9115515

you need to train more, that's classic mistake that people who are starting make. I remember that when I was starting with math I would make those kinds of mistake every fucking time, but after a lot of pratice it's now very rare.

You're not a brainlet anon, just study more and problem solved.

Didn't use math other than simply addition and subtraction in 20 years. I honestly don't remember how. I probably could work it out somehow but I don't feel like it so I came here.

Problem:
Going /out/ in a few days and decided to take some milk powder with me. It needs to be mixed with hot water (50°C-60°C) but not boiling hot. Can't measure anything other than seeing the water actually boiling.

With how much cold water (10°C-18°C) and how much boiling water needs to be mixed to get the desired temperature for the milk powder?

How long does it take for a "steel cup" (500ml) of boiling water to cool down to milk powder mixing temperature if the ambience is 21°C?

How do the results of those question change when it's done 1000m above sea level?

>...change when it's done 1000m above sea level

Thanks for the laugh.

I bet you finished high school as well. This is why we radically need to change the school system and cut off people like this.
>>
>>9115453
>wind, time
Isn't needed for the first question, you can ignore those. For the second question the result is obviously time so it's for you say and if you want to include wind let's say it windprotected or up to slightly windy.

My stupidity isn't a constant so let's ignore it there too.

>>9115458
you just don't know how to calculate it. at least I'm not pretending.

Where do you download your books from? I need this one right here. pls gib sauce

I have always found how communities change and evolve to be extremely interesting. I even like making mini ecosystems with terrariums filled with Plants and insects to see if they can survive and populate. Are there very many jobs in biology fields that deal with studying/managing population, ecosystems or evolution?

Just kidding. In all seriousness, what you're talking about is a beautiful subject that unfortunately I have limited experience with. My experience with this has been limited to using R to model ecological and epidemiological systems, but from what I've seen there are algorithms/programs out there used to model ecosystems as diverse as what was in the OP. Not sure how you feel about coding, but it certainly wouldn't hurt.

tl;dr Interesting subject. Not sure about job market. Learn code (R to begin with).

What does /sci/ think of this book and the theory? Is it a valid explanation of rapid modern human traits development, or ramblings of a brainletr?

Evolution is a fraud. It was made up by the government to weaken our faith in god. But true christians like myself know the truth. You should stop reading science shit and start reading the bible. Science is all fake. God created us and everything around us. You do not seriously believe in this retarded big bang shit "HURR DURR NOTHING EXPLODED ONE DAY AND CREATED EVERYTHING!!!!" or Evolution "HURR DURR ONE CELL ORGANISMS EVOLVED INTO HUNANS!!!!" If evolution is real, why do we still have one cell organisms? Why do we still have apes? Why don't the evolve into humans? The reason why is because everything was created by a higher force. All you scientists will burn in hell because you were blinded by science and forgot god. God, who is our lord, our father, our creator. I have an IQ of 168. God gave it to me that I can spread his message. Death to science. Science is sin. Please do not argue with me, I am more intelligent than you anyway and you will just humiliate yourself in front of everyone, and that's not my intention. My intention is telling the truth. And this is the truth. The ultimate truth. Everything else is just untrue. Your little science shit can't save you when you will suffer in hellfire for eternality.

sorry bait boy, most christians don't believe in this.

I never really studied it, sounds weird. Can you explain more or at least give me some links?

>>9115349
Well, between 100.000 and 40,000 yrs ago humans went from simple stone tools to language, art, hairlessness, hidden ovulation and breasts in women. Accelerated development of such complex traits in a short time has been baffling. The author argues it was a response to an evolutionary pressure, namely humans were hunted to near extinction by stronger, smarter and ruthless possibly nocturnal predator, neanderthal. This is in a nutshell, havent read the book yet (started reading today), but check out the website for more.

So supernovae caused elements to disperse into the universe, eventually forming our solar system, rocks formed together to become earth, where did the stuff that was chemicals that turned into microbes on primordial earth come from? I'm trying to understand abiogenesis

From supernovae. All elements other than hydrogen and helium were made inside stars.
>>
>>9115334
And so elements traveled from outerspace to the surface of primordial earth? Or were the elements that turned into life already there when the earth rocks began forming together?

because autists can't recognized that the whole universe is designed, the whole freaking thing is a THOUGHT. God = Logos, the WORD then became FLESH. Our Lord and Saviour Jesus Christ.

Mathematics are the abstraction of multiplicity and its consequences.
When you notice there's something in common between two rocks, two days, and two wolf howls, you can abstract out that thing they all have in common, label it "two," and begin deducing truths about it.
>>
>>9115295

No, math exists as patterns in human brains. There are no "immaterial" things, the concept isn't even coherent.
