science is so cool XD i'm such a nerd XDXDXD

>riddle
>bayesian statistics

this is at least one of the more cleverly disguised homework threads, OP, i'll give you that.

you're still a faggot, though

2 in 10,000 people have kidney cancer.
1000 in 10,000 people have microscopic hematuria, including you.

You have a 1 in 500 chance of having kidney cancer.

It does seem like that now that I think about it because the riddle is too simple. Here's a harder one for you, faggot:

>Joe is a dude with many ducks. Joe went to the market to sell said many ducks, but can't count pass 100. He does, however, know this:
>If you divide the number of ducks by 1, there will be 1 duck left.
>If you divide the number of ducks by 2, there will be 1 duck left.
>If you divide the number of ducks by 3, there will be 1 duck left.
>If you divide the number of ducks by 4, there will be 1 duck left.
>If you divide the number of ducks by 5, there will be 1 duck left.
>If you divide the number of ducks by 6, there will be 1 duck left.
>If you divide the number of ducks by 7, there will be 1 duck left.
>If you divide the number of ducks by 8, there will be 1 duck left.
>If you divide the number of ducks by 9, there will be 1 duck left.
>If you divide the number of ducks by 10, there will be 1 duck left.
>If you divide the number of ducks by 11, there will be no duck left.

>How many ducks did Joe have?

>>7706306
you don't, you just think you do because drinking makes you less autistic

>>7706306
Thats a real phenomenon youre not imagining it. The second you have 1 too many it goes the complete opposite direction so reserve the drinks for study time not for exam time.

>>7706311
I'm not autistic, I think. I do notice that I don't overanalyze the questions when I'm buzzed.

>>7706321
Ok, will I.

>>7706269
wtf do your feet look like dude? jesus

Because we're birds, duymbass.

Mathematics is the language of the universe, but not the functioning of the universe.

Feynman gave a fantastic presentation about it during his Messenger Lectures.

Nice Meme

>>7706317
There isn't a meme though

Write down relevant formulas, study them, know them inside and out. That is a start.

Should've done the coursework, plebbo, now you will soon know the grave mistake you've made by jacking off to animu all day long.

>>7706258
go through physics II book
write down on your shitty notecard every formula that comes up. should all be about magentism and electrostatics

go to test

find which formula you need to plug numbers from problem into to get right units

still probably fail the course because you haven't done enough other work that a passing test will also pass the class

They should put some refugee camps next to it
just in case

You can't swim yet you're asking to dive in the deep end

>Is there any recommended book or resource that explains these concepts without relying too much on higher level mathematics (if such a thing is even possible) while at the same time not going full on retard popsci?
Dis nigga

>>7706098
Yeah I was worried that that would be the case

Any resources that introduce higher-level mathematics alongside physics as they are needed and appear?

I'm not looking to draw my own conclusions or anything like that, I just want to broaden my horizon on the current standard model and understand a simplified version of it

>>7706087
Penrose's Road to Reality.

>>7706078
last thing I used was libgen but I saw a thread on /g/ a few weeks ago saying it was getting shut down or something.

>>7706078
Have you considered buying the textbooks like someone who isn't a fucking nigger?

>>7706082
Thank you for the link! I've found Levine's one
>>7706083
We all know how expensive these books are

This, it causes your testosterone to decrease rapidly, I lost 3 inches off my dick and I was only showering 2 hours a day, don't do it OP, it's not worth it.

>3-4 hour sessions

Jesus christ that's a long shower.


>lie down and sleep under the shower head

Do make sure you don't block the drain with your body, people passing out in the shower and doing that can lead to some serious water damage


Other than that, I would reason that professional swimmers probably spend a lot of time every day in water and they seem fine.

Humans are social. Close emotional attachment is to be expected. It has various benefits.

Humans neocortex (the outer brain, the conscious and "smart" one) is directly connected to the limbic brain (the emotional one, not conscious). You can't chose who to love or like, the limbic brain automatically selects who is "perfect" for you; since the limbic brain is deeply connected to the neocortex we will feel attachment to someone that's not part of our family (animals like dogs start liking you because you maintain them, their limbic brain is really developed but their neocortex is not half as developed; humans can have "love at first sight thanks to their neocortex").
Basically, the limbic brain detects that someone is perfect based on previous experiences and personality of a person and sends the information to the neocortex; thanks to the neocortex we become conscious of the " perfect person" and the felling becomes permanent until some information of the person changes. That is love

>>7706220
>You can't chose who to love or like, the limbic brain automatically selects
This is near universally wrong. You can most certainly choose how you want to feel, it can feel real, and you can do it for years.

Not to sound like a prick, but don't assume your own lack of mental exploration and slave-like mentality constituents the truth of how the human machine works, and can be made to work. You can choose how you feel. You always could, you always can.

But you probably shouldn't.

Nobody cares if it's more viable for a colony. We like Mars better because it has a lower gravity (lower escape velocity) and more usable materials. I know that Venus is more suitable for human life, but what's the advantage of going there? What is the human race gaining? Going to Mars allows us to more easily mine from the asteroid belt, and that's what space exploration has always been about. Exploration of new frontiers is fueled by resources; human colonies just provide a bigger customer base.

>>7705967
>I along with the rest of /sci/ laughed at him.
If by "rest of /sci/" you mean that one asshole pushing your confirmation bias sure.

We ain't colonizing shit in our life times anyway, get over it.

>>7705967
>240x the solar power available

lol no, 240 PERCENT

>75 degrees Celsius is easier to deal with

No it isn't. Making something warmer is much easier than making something colder.

Beyond that, not having access to the planet surface makes things a lot harder. On Mars, you don't have to bring most of your building materials with you - just tunnel in. On Venus, it would be more like being on a space station - just much harder to get supplies to, and dealing with hurricane force acid winds. Even without those problems, nobody has ever lived long term on an airship even on Earth - think about the reasons why not!

All l that being said, a Venus atmosphere colony is not totally stupid. But I really don't think it's realistic in the near future.

take derivative
set to 0
check boundary conditions

>>7705936
>Final is in 6 hours
If you haven't studied yet, you are fucked nigga

>>7705942

This is what I do:

1. Find objective function
2. Identify constraints
3. Reduce objective function to one variable
4. Identify domain of objective function
5. Differentiate
6. Find critical numbers by setting to 0
7. Test critical numbers using on of:
a. closed interval method
b. 1st derivative test
c. 2nd derivative test
8. Answer

Hardest part is easily steps 1 and 2. Sometimes step 5 is tough if I have to differentiate something messy. The rest is easy.

Last time we had a thread about this. Some faggot kept posting pictures of pigs and rats with tumours and blatantly lying to promote the anti GMO agenda.

What I got from that thread is that GMOs are perfectly safe, but there's a big economic argument to go against them: GMOs are the future and they're going to crash smaller markets. This is a reason some countries are banning them.

bumpan with zincfinger, because it's what I know and love

>>7705887
They threaten the whole bullshit non-GMO market which makes billions.

So some corporations throw a few million dollars to San Francisco natives to go smell bad around labs.

I remember reading an article from a Monsanto research head a few years ago about how the focus was going to shift from optimizing the crops themselves to optimizing where the crops grew, focusing on the soil's superregional ability to support certain crop types better.

It would make harvesting a pain, but it was an interesting idea.

You mean while it's full of magma? Some kind of magma-related shenanigans, I'd wager.
