I'm downloading the hd 60fps video editing version I'm in TOO FUCKING DEEP TO GO BACK NOW
How accurate is this anyways?
What DOES google use reCAPTCHA data for anyways?
nice try moot.
also how the fuck does solving captchas make an AI "learn" shit ?

I never bothered to read up on what they use the picture captcha for but as far as I remember the word captcha was used to improve the accuracy of scanning books and converting them to text

Why else would it give you "captcha incorrect, try again" for choices that are obviously correct?
in b4 retard, don't act like you've never picked 4/4 street signs and have it tell you "wrong answer"
What do you do if you've just found out you just 15seconds ago had unprotected sexual intercourse with someone who has an STD (let's say herpes)? Do you quickly run to the bathroom and soak your gooch in water and call the ambulance to get antibiotics or something? Surely there must be something you can do to reduce the risk of infection.
You know, just in case, I like to be prepared.
I don't know the biology of it, so that missing knowledge would be a reason to wash my dick, yes.
I also know that a great bunch of girls have herpes anyway.
Herpes isn't that contagious when she doesn't have blisters. Washing won't do shit, and you could take antivirals for the rest of your life to prevent outbreaks but that's retarded.
Drinking anything you can that makes you piss a lot would probably help flush out your urinary tract. Other than that, I don't know, but I'm looking forward to see other answers.
Have a math problem you're having trouble with?
We're not going to do it for you, but we can help you understand the process.
Have some math that you want to have checked?
Here seems like a good place to do that.
I like this new thread idea. More actual discussion on /sci/ and less shit posting I will start us off with one.
What is, If at all, the relationship between the centroid of a region and the equilibrium points in Lotka-volterra predator and pray systems?
Let [math]F:M \to N[/math] be a continuous map between smooth manifolds. I want to show that if smooth real valued functions on all of [math]N[/math] pullback to smooth real valued functions on [math]M[/math], then [math]F[/math] is smooth. I get the idea -- given a smooth chart [math](V,\psi)[/math] in [math]N[/math], we want to say that [math]\pi_1 \circ \psi \circ F[/math] is smooth ([math]\pi_1[/math] is a coordinate projection), but we can only say that smooth functions on *all* of [math]N[/math] pullback to smooth functions, right? What's the way around this?

It's been awhile since I've taken any kind of calculus, so I'd appreciate it if someone could check this for me, since I'm working on my own at the moment to refresh what I've lost over the years:
If I wanted to find the surface area of a rocket nozzle with a curve modeled by the equation [math] 3 + \left( \frac{\ln{(\frac{x}{2})}}{2} \right) [/math] with a domain 0.005 ≤ x ≤ 9 rotated about the x axis, would the equation be the following?
[eqn] \int_{0.005}^{9} 2 \pi \left( 3 + \left( \frac{\ln{\frac{x}{2}}}{2} \right) \right) \cdot (9-0.005)...

Solidworks
Anybody have a decent link to a torrent for solidworks... need that shit desperately
Just go to your universities library and use the computer lab. It usually has it installed.

/sci/, do receding gums ever grow back? google only returns spam sites for this query
Yes, after they are healthy again.
>>7849028
Do you know of any papers on this? If not its ok.

>Question that could easily be asked to a dentist
>Question that implies that you have said problem and should go to the dentist, not only to ask, but to get proper examination
>Posts on 4chan to ask random people on the internet
No, receding gums never grow back because they are a sympton of testicular cancer, which means that luckily for us, you will die in 2 months and thus will never propagate your shitt 2 digit IQ genes.
if there were an Atom made of one proton, one electron and one neutron, would it not be completely neutral in charge due to the proton and electron canceling out each others charge and the neutron being neutral... and thus not interact with what we understand as reality?
It occurs to me that the probability of there being atoms with every conceivable combination of particles becomes more likely the least amount of atomic weight and this particle, if it does exist, would be 2nd on the periodic table.
iv very curious about this. please debate !
>>7848996
It wouldn't be completely neutral. Your basic chemistry understanding of the model of the atom is wrong
It would be neutral from far away. In the near field however, there will be fluctuations with time. Example: water molecules are neutral from far away, but close by they still attract due to their charge difference on the oxygen and hydrogen sites.
>>7849015
What would constitute true chemical neutrality then?
my understanding of chemistry is limited to pool chemistry.

This is probably the best advice I got but too late. I wasted years trying to get good at STEM subjects but to no avail. It was only too late that I realised trying to get good at STEM was essentially a sunk cost fallacy for me. I hope this helps someone who is in the same situation I was. If you're getting stuck and frequently find yourself asking for help for like a math or physics, just drop the subject immediately...

That is terrible advice, lol
it's not sunk cost because you develop the greatest problem solving ability from struggling through problems and finally solving them with a flash of insight.
I know 4chan is just trolls and people trying to bait eachother with discouraging advice and telling eachother to commit suicide but come on.

/pol/ talks about this regularly, in a survey done last year 96% of all electrical engineers in the US had IQs above 130.
How do you tie an ethnicity to genetics?
haplogroups
imminent >>>/pol/ invasion, everybody abandon thread
>>7848675
you don't
you tie data to regions and faces
∆ frequencies of particular Single point mutations are used
ethnicity isn't a thing unless you're tracing tribal origines, look at the data from the Ashkenazim jews
>>7848686
Since when are ethnicities based on haplogroups?
Ethnicity is a much older concept than that.
>>7848688
>you don't
That's what I think as well, but how do I proof something that doesn't exist?
>∆ frequencies of particular Single point mutations are used
Can you break that sentence down to me a bit?
Do you locate those mutations in the current time or might they reach into the past?
Does slowness to grasp something equal stupidity?

if i get a Physics degree, can i still do certs like in CAD and work in engineering as a technician or something? i'm just curious about my options, like if you have to be accredited to be an engineer no matter what, of if there are other positions that are technician tier.
>>7848592
If you want to work as an engineer then why the fuck would you not study engineering.
ffs some people are just too stupid to reason, JUST CONNECT THE DOTS MAN, IT'S NOT THAT HARD.
>>7848634
>I don't want to be a physicist or do any kind of related work in pure physics
>I want to be an engineer/work in engineering
What is the best choice?
A) Get an engineering degree and become an engineer
B) Get a physics degree, then spend months getting certifications, then spend years looking for an employer so thirsty for employers that he choses me over a real engineer, and then get paid only 50% of what the real engineers are...

Hey so I've been learning Java for a little while and have now started with python. I was watching tutorials on slice and lists and I was wondering how you could print out the last letter of a string. An example would be the last letter of each word in this post, I know you need to turn it to a list. I saw further tutorials but no one really answered my question so I was wondering maybe you dont use slice for this but you use is.alpha?
Many thanks for helping !
>>7848507
maybe
print(yourstring[-1])
will do the job...
just watch thenewboston tutorials. he explains it for total noobs
Thanks for answering but I think that will only give me the last letter of the entire string and not the last letter of each word.
yourstring = """ I want to learn programming"""
#Lets say i want the last letter of each word.
mylist = yourstring.split()
would print(yourstring[-1]) do the job?
So LIGO results get published tommorow. Probably. How many of you have your GR up to scratch enough to read the paper?
bump.
interesting
This will happen:
- half the theoreticians will see their pet theories buried alive
- the other half will try to find more evidence for being right
- string theoreticians will yet again dial another set of knobs and exclaim this fits well with their existing framework.
I confidently ignored the waves chapter in Wald back when I had my GR lecture. I probably should read up on it when exams are over.
It's a old article, but:

I don't understand why our species insists on keeping our defective members alive. Before you get emotional about >muh life, consider that we chemo cancer cells because they are defective even non-malignent ones. We do the same thing with animals.
So why do we insist on keeping gays and trannies alive?
>>7848428
I would consider people who lack empathy to this degree to be "defective"
How many consciousnesses does it have?
