>Fossil footprints laid down more than five million years ago in what is now Crete could belong to a previously unknown primate, and perhaps even an ancient hominin — an animal more closely related to humans than to chimps.
>Per Ahlberg at Uppsala University in Sweden and his colleagues identified more than 50 fossil traces in an area less than 4 metres square. The animal responsible for the prints — left some 5.7 million years ago — was probably claw-less, bipedal, walked on the soles of its feet, and had other hominin-like characteristics.
>The authors say that the interpretation of these footprints as belonging to a hominin is controversial, because Crete is some distance from all other sites featuring hominins of a similar age, which have been found in Chad, Ethiopia and Kenya. If the animal that made the prints was not a hominin, it must have been a previously unknown non-hominin primate that evolved a human-like foot independently.
Human polygenetic origin confirmed?
>>9145292
>polygenetic origin
eh?
>>9145320
No. But if it DOES turn out to be a hominin, then faster radiation than previously theorized would be on the table.
>>9145292
I really don't buy the 'convergent evolution' explanation. I mean, a biped ape/primate unrelated to hominins with nearly human-like feet would likely belong to a relatively big taxomic group, which would certainly leave some traces behind. But nothing in the fossil record indicates the existence of such a group of creatures.
This is really something.
Affirmative Action makes zero sense under any context.
1. Black Student
70% white genetics, 30% black genetics
2. Black Student
5% white genetics, 95% black genetics
Both are considered the same classification in Affirmative Action. All AA does is give huge advantages to people who kind of look hispanic/asian. There is no rational basis behind Affirmative action that makes sense under any type of intelligent analysis (120+ IQ). Rich 70% white/30% black students can get the same score boost as 90% black ghetto students.
AA makes zero sense. All it does is give highly white/asian people that can say they are black or hispanic a huge advantage. I am 100% sure that you will see huge standard deviation skews of "hispanics" and "blacks" in college/AA positions to being highly mixed with white or Asian.

>Affirmative Action makes zero sense under any context.
wrong, it makes sense after enslaving and committing hundreds of racist atrocities towards the black community and then somehow expecting them to just be fine as soon as you a few laws say that they're equal
>>9144804
meant kind of look black/hispanic instead of asian.

It makes 0 sense even if they were fully black/white/whatever. If anything we should be promoting the demographics with lower %s of things such as drug use, even though it would be unfair with the people of the demographic that don't fall on the average.
What is going on here? I have a simple function y=sin(2pi*x). I only care about 0<x<1 The local maximum and minimum are easy to calculate, even when the period changes. The amplitude is a constant 1.
Now I want this sin wave to lose amplitude over time. So I multiply it by (1-x). This way it is at maximum amplitude at time 0, then loses amplitude until it reaches 0 at time 1.
But when I do this, the time of the local maximum and minimum change. Since the amplitude is being scaled down linearly, I expected the time of peaks and troughs to remain the same while the actual value gets closer to zero. Instead, the times are changing as well.
So I would like to either
>figure out how to calculate the new min and max times when sin(x) is multiplied by (1-x)
or
>replace (1-x) by another formula so that the times of peaks and troughs are conserved but amplitude is still lost over time.
Pointing me in the right direction if it's too difficult to solve would be appreciated.
The positions of the maxima are changing because the (1-x) term changes faster than the sin term close to the sine's peaks. Exponential decay would do the job, but won't be linear.
>>9144593
I don't mind exponential decay, but is there a single exponent that will preserve the times of the peaks and troughs?
>>9144613

What does it mean to "write the sum"?
The exercise instructions are as follows:
> Write each sum. Then answer the question.
Do they mean to write the mathematical expression (summation), then provide the answer (sum)?
what level ?
middle school for the retarded ? learn to use Sigma and write the sum without computing the closed form
college ? compute it, even if it's not asked it shouldn't be too hard I guess
>>9144450
I tutor children at all levels from all over the world; this particular example was for K-1 students.
I find it to be a poorly formed instruction that is probably a simple mistake on their part, but I wanted to find out if this wasn't some kind of regional misunderstanding.
If it is just a quirk of the language found in a specific region, I'd like to know that and be able to research it so that I can explain it rationally to people.

Is it worth it to learn a foreign language to read math and science papers in those languages?
Do you want to give up 4 years of your life, dedicating an hour a day studying a language, and all the time required to learn how to go about learning a language and acquiring materials, just for that? It's quite a personal question, isn't it?

Well not all science is published in English
There are people on /sci/ right now who aren't aware there are large scale, bigger than Manhattan project, efforts to create AI.
It's pretty fucking obvious, even Intel has held back it's public progress and kept it secret. There is a reason for everything. Right now there are large-scale projects around the world that are covert looking to make super intelligence.
https://www.rt.com/news/401731-ai-rule-world-putin/
“Artificial intelligence is the future, not only for Russia, but for all humankind. It comes with colossal opportunities, but also threats that are difficult to predict. Whoever becomes the leader in this sphere will become the ruler of the world,” Russian President Vladimir Putin said.
If we become leaders in this area, we will share this know-how with entire world, the same way we share our nuclear technologies today,” he told students from across Russia via satellite link-up, speaking from the Yaroslavl region.
>>9142400
I agree
I think Google is using captcha to train theirs
>>9142405
Of course. There is a problem with "secret" projects though in that many will have horrible leadership via bureaucracy. So even public projects in AI probably are beating them in many areas.

literally everything is genetic. Genetic Determinism is reality. Once you accept it the world makes a ton of more sense as well, aka Africa/South America/India/China etc all become predictable.

How useful is a Political Science degree?
I'm considering getting a PoliSci degree that would allow me to get into Law School, but I'm wondering how useful the degree would be if I decided not to pursue law after finishing the degree. I'm sure it would be more useful than something like Philosophy or Criminology in terms of real world application and Law School potential, but all in all I'm not sure.
Thoughts?
