Just realized most of /sci/ or at least some of /sci/ is the white/satanic version of lucifer. Didn't even know one existed as I was the black version.

I hope you enjoy your time at harvard, and whatever other cesspool's you'll be going to since when the christ comes for you, it won't be easy or short. Both my condolences and hatred goes out to you, its do to your "Superior genetics".

1. Kèk why are you assuming that none of us believe in a higher power? And then you act as though hatred is at all appropriate with your religious tone? The Messiah would instruct you otherwise.

2. You should realize that knowledge of hard science has a fairly steep learning curve right? Just keep working on it, friend.

3. Unless you've done a thesis on genetics and epigenetics across various geographical locations, you can only make a very thin claim about it. "superiority" of genes is relative to the evolutionary needs in a given environment and IQ is determined by your Performance on a specific test. If you suck at taking tests, like me, then that measure is going to be an unfair assessment and your results will likely vary if you take the test more than once.

4. You should drop the intellectualy lazy (racist) attitude. The playing field is leveling in North America so if you apply yourself you could probably thrive as a scholar since universities really want multiethnicity in what's still a predominantly pale-skinned institution...which means you get a slight advantage.

5. Not all pale skin is the same. Some of us have been brutalized by imperial forces over the past century, especially Eastern Europe. Much of that region was basically enslaved to Nazi and then Soviet control for upwards of 60 years. Many of us feel solidarity with your group and others. Don't spit in the face of potential allies.

Say I had a population of 10 people with ten scores.
The mean comes out to 900 with a standard deviation of 100.
That obviously means that one standard deviation is between 800 and 1000.
That said, assume I had two outliers of 799 and 1001.
Evaluate my assumption and tell me if this is considered correct.

With a population of 10 sets of scores, 80% of the data (8/10 = .80) falls within one deviation from the mean. In other words, out of ten scores, eight scores fall between 800 and 1000, with a mean of 900 and a standard deviation of 100. (N = 10).

Is this description accurate?

Is it possible for humans to create an apocalyptic asteroid strike on earth by launching something big enough into space then make it slam back down?

1 replies omitted. Click Reply to view.
>> No.9685531


>> No.9685630

Asteroid impacts are so destructive because they are moving at very high speeds relative to the earth, often more than 20 km/s. If you just lifted some big rock up and let it fall down again it wouldn't be going anywhere near as fast, sure it would probably fuck up whatever it landed on but the energy required to do it would be a waste of time.

>rocks dropped from there

>> No.9685793


>> No.9685845

Not directly.
Firing something into space and letting it fall back is just (partially) converting the energy in the fuel into the kinetic energy of the rocket and then back into heat when it hits.
Might as well just explode the fuel at ground level.
Your scheme doesn't created any energy.

On the other hand, you must be aware of plans to deflect an asteroid away from Earth if it was on an impact trajectory. Works in reverse too. Move an asteroid which was scheduled to barely miss us so that it hits.
The energy is already in the asteroid. We're just making a minor adjustment.

Hi /sci/, could you explain me how to get formula S=π.r^2 by integration in polar coordinate system?

>> No.9685518

The angle (θ) goes from 0 to 2pi, and r goes from 0 to r, then you just integrate the usual formula for surface in polar cordinates. /dθ/r×dr, which when you solve you get pi×r^2 I don't know how to use the stupid math thingy to make it look nice so i nust used / for integrals but you should get the point.

y=kx means that the function will always be the same line when graphed
If y=k+x the line graphed will always be offset from origin by whatever value k is which doesn't do as well of a job at explaining the concept as y=kx does since y=kx never moves anywhere.

The technology is advancing too fast in genomics. It's like the computer revolution but less of a consumer toy so you don't notice. The only way consumers notice is things like 23andme and testing and maybe medical care.

This technological advancement and the breakneck speed of it means all of the hidden aspects of genetics are becoming revealed. GWAS into IQ and Education attainment can be used to create predictive models to do novel things like estimate a probable adult intelligence of an embryo. Gaps in Intelligence between races will be unavoidable and so the movement to position the academia and intellectuals in a tenable position is happening. Since their current position is to deny it outright and lynch anyone who brings it up.

>> No.9685236

race is an outdated concept, geographic clines are more accurate. Genetics will show continual gradients between populations and will show which groups of people are truly isolated.
