I am aware that this question is usually asked much, but what exactly is a Psycopath. What key differences do they have between average humans, hence why I am not using Google.
I want to observe the different opinions on what it actually is.
>>8020906
the difference is a thing we like to call
pseudoscience
>>8020906
A person who employs strategies that are seen as unconventional when viewed with empathy.
>>8020911
This. We are all psychopaths s psychopaths are us. But the most important fact is that in every psychopath we are there with them.

Well, /sci/? Which is it?
Fuck you and your easy stupid fucking question

If it's so easy why don't you tell us the answer?
>>8018088

Can I complete an undergraduate degree in Computer Science if my IQ is ~110 ?
I'm shitting myself over this idea that I may be biologically incapable of grasping enough material no matter how much effort I put in. I'm freaking out because I originally enrolled in a masters physics course a few years ago before dropping out and finding it too hard to justify the amount of effort required.
How do I test myself to know whether I pass the intellectual requirements for this course? I've already been accepted but I don't want to drop out again. I'm...

See, even now I've fucked up the OP image. Should be pic related.
Almost anyone can learn the material given enough time, exposure and help with the material.
Google growth mindset vs fixed mindset.
The problem here is that extra time, help, etc will require extra sweat, blood, tears, and money.

According to the creator of this dataset, those are estimated IQ scores based on SAT scores.
As you previously posted, there's little meaningful pattern to the verbal scores, so that graph is primarily based on the quantitative portion.
So, it's just another way of restating the known finding that the more math-heavy a field is, the more male it will be.
Well, /sci/? If you take the Bayesian utilitatian approach, the proportion must become sound enough.
Or maybe Eliezer Yudkowsky's just wrong because he's a JEEEEEEEEW.

"There are sub-species of humans"
Sci I need your help. Self teaching A-level maths and this may sound like a dumb question but does it matter what way round your simplified equation turns out to be?
3ab-3ac+3a-7ab+5ac
I came to the answer -4ab+2ac+3a
However, in the answer book they've written it as 3a +2ac-4ab
Is my answer still correct, or does having a negative at the front make it wrong. aiming for an A star and having looked at maths in years, and i don't want to go into an exam and lose marks on something little like this. Thanks
>>8019138
your answer is the same as the one in the book, where the negative term is doesn't change anything since addition commutes (order doesn't matter)
no one would dock you marks for this
You couldve literally plugged n chugged both answers and get the answer to your question quicker than posting a thread about it on /sci/
>>8019155
I'm not looking to save time though, slow and steady wins the race. I'd rather spend 5 minutes getting solid advice from more qualified people, with explanation, than trial and error without being able to explain it and losing marks on an exam,
Can someone explain why even among environmental activists, Global Warming is now referred to by the euphemistic "Climate Change?" I think this just feeds public apathy to the issue- "Climate Change" sounds so benign and natural, it's basically conceding to the anti-anthropogenic origin crowd.
>>8016891
Because when you call it global warming, you have fucking idiots walking into congress with a snowball.
who cares ? this is an /x/ subject, not a scientific one.
geology thread.
What kind of math is useful for geologist, outside of the usual differential equations and linear algebra?
What specialty of geology, interests you?
seismology, geochemistry, geophysics, marine geology, paleontology, hydrology etc.
>>8007856
Yourmomlogy

Statistics
The only geologists that get paid are the ones finding gold, oil, iron ore etc and you need some pretty advanced stats to do that
I'm into biology & chem but I've encountered some geologists when working with diatoms. I even have a meteor piece from Dr. Richard Hoover at the school's lab.
/Sci/, why the doctor hate?
Sure, 4 more years of schooling after undergrad, but all my med school friends have time to go out, exercise, activities, etc.
>Long hours
Yea, but not too bad depending on specialty. Dermatology is 45 hours per week. PMR and Psychiatry are 50. Options to work part time.
>Bad pay
Except not. Not God-tier, but high job security and ability to live comfortably.
>>8002685
>dermatology
>psychiatry
>real doctor
Pick one
>>8002685
I remember an anon that wanted to kill himself because of how horrible and stressful the job was, how bad the decision to go into the long journey that med school is, and how narcissistic his colleagues had to be to ever enjoy being a doctor.
>>8002685
I think the general consensus is that we have great respect for medical doctors but the vast majority of us would absolutely not want to be one unless it's one of those relatively less stressful ones, like an optometrist or pediatrician
McCulloch says there is observational evidence for this in the form of the famous fly by anomalies. These are the strange jumps in momentum observed in some spacecraft as they fly past Earth toward other planets. That’s exactly what his theory predicts.
The idea is that if photons have an inertial mass, they must experience inertia when they reflect. But the Unruh radiation in this case is tiny. So small in fact that it can interact with its immediate environment. In the case of the EmDrive, this is the truncated cone.
The cone allows Unruh radiation of a certain size at the large end but only a smaller wavelength at the other end. So the inertia of photons inside the cavity must change as they bounce back and forth. And to conserve momentum, this must generate a thrust.
Crucially, McCulloch’s theory makes two testable predictions. The first is that placing a dielectric inside the cavity should enhance the effectiveness of the thruster.
The second is that changing the dimensions of the cavity can reverse the direction of the thrust. That would happen when the Unruh radiation better matches the size of the narrow end than the large end. Changing the frequency of the photons inside the cavity could achieve a similar effect.

Holy shit this is it, we were born at the RIGHT time! The explanation seems legit.
All the bitter contrarians and skeptics on /sci/ are going to attack this like rabid dogs so is there a Reddit thread where I can discuss this in more detail?
if the thrust involved is tiny, why are people predicting flying cars and shit from this experiment?
Is Philosophy useful at all, has it achieved anything?

What board did you think you were browsing?
No it's an intellectual deficiency. People have known this for a long long long long (x99) time
>We physicists do have greater freedom than our engineering peers, in that if we don't like our chosen careers, we can always pursue another, since we are equally qualified for any number of technical disciplines. James Smith, Rockville, Maryland.
what did he mean by this?
James smith never accomplished anything noteworthy, while we have things like one world trade center
>>8015083
>James smith never accomplished anything noteworthy
engineers are less than non noteworthy though. like they go out of their way to inhibit progress with regulations.

it's called safety and it's what stops your diabeetus pump from killing you.
Good luck anon.

Damn, it was a good problem. Too bad it is a troll.
Here is what could be done, and I did. Label all the unnamed sides. The one below I called x, the one to the left I called w and the one that is part of the "10" in the hypotenuse I called w.
Then you can find an expression for both x and y in terms of w.
After that x squared + y squared = 10 and by expanding this you get a second degree polynomial.
After that it was fun but then I found out that the roots of the polynomial were...

How can time exist? In the space between 10:00 and 10:01, there is an infinite amount of time (e.g. Achilles and the tortoise paradox). How can we even reach the next second? Please help, /sci/, this has been boggling my mind for months now.
>>8016791
>what are convergent series
>>8016791
What's really weird to think about is that time isn't really passing at the same rate ever
There's not an infinite amount of time in one minute. There's one minute in one minute.
You can split this minute into infinitely small fractions of a minute, but there's not infinite time in one minute.
Gold was is and always will be valuable material throughout the years.
Post anything you know about this marvelous material, in regards to manufacturing, recovering, historicly, selling, buying, industrial, homemade etc... absolutely anything you know and would like to share about it.

>historically
The first Lewis acid catalyzed enantioselective aldol reaction was carried out using an Au(I) based catalyst. (Hayashi-Ito aldol)
The above is hardly ever used. Other methods have better scope (some are catalytic in chiral material, others are not).
Most gold catalysis is unlike the Hayashi-Ito, most uses Au salts as pi-acids.

Its color and other properties are due to relativistic effects.
