/sci/ I need your help, over on /vp/ in a trivia thread someone tryed to state how many kinds of pokemon could be possible, and another person stated they forgot to account for IVs, cutting the crap here, up to 255 EVs can be put into one stat, and there is a total of 510 to distribute between the 6 stats, how many combinations of EVs are possible?

First half is the total number of combinations. The second half (past the sigma) accounts for and subtracts whenever a stat overflows. Only one can overflow at any one time, making it a bit easier.

Do you believe that a scientific advancement race in these two areas is the major tug-of-war in world power?
Interesting Excerpts below
http://thediplomat.com/2017/08/the-great-us-china-biotechnology-and-artificial-intelligence-race/
Explain the motivation behind Chinese investment in U.S. genomics and artificial intelligence (AI).
With large public and private investments inland and in the U.S., China plans to become the next AI-Genomics powerhouse, which indicates that these technologies will soon converge in China.
Using AI systems to understand how the functioning of our genomes impacts our health is of strategic importance for biodefense.
Gaining access to increasingly large U.S. genomic data-sets gives China a knowledge advantage into leading the next steps in bio-military research. Combining host susceptibility information with pathogenic targeted design, malicious actors could engineer pathogens that are tailored to overcome the immune system or the microbiome of specific populations.

Yes.
This will be the Space Race of our era. USA will probably fizzle out though because "b-but you're devaluing this Downy's life" or some gay shit.

Hi /sci/, I was hoping that maybe you would know this. Photodetectors have different efficiency for detecting photons in one polarization (let's say vertical) and other (eg. horizontal). What are the differences in these detection rates? How much more is one type of photons detected instead of other?

It depends on the type of detector.
The most common types of semiconductor materials (Si/InGaAs etc) are made of isotropic materials, so they are not usually polarization sensitive.
There will be polarization sensitivity if the light is not normally incident (i.e. not straight on), but this is not intrinsic to photodetectors. (fresnel equations).
You can make a polarization-sensitive detector by creating anisotropy (birefringence) in the material. There are ways to align molecules in the detecting material so that significant absorption will occur only when the polarization matches one axis. Basically you engineer the material to have linear dichroism.

Here is some food for thought, OP. All the jobs in liberal arts are stupid hard to get. You won't be a historian unless you want to be a teacher. If you major in history, you'll be paid for your writing skills.

Hi, /sci/. I need help because I'm writing some sci-fi shit and I have to explain how a particular exotic material works as realistically as I can because I'm too autistic to just say "dude science lmao".
The idea is a treated gelatin or rubber that absorbs a reletively significant force applied to it and redirects and/or converts it however necessary to say power weapons and armor, charge batteries, break somebody's hand twice as hard if they punch you, etc. without suffering the consequences of impact.
The material itself absorbs a little bit of net-force, but it's obviously pretty OP so that's often negligible and pretty much renders attacking with physical force pointless unless you apply enough at once to overwhelm and destroy it.
I know just fine that this breaks plenty of natural laws, but what I'm asking for are what laws this wouldn't break so I can minimize the horseshit I have to lie about. It'd also be nice if anyone has a better idea of the same concept, but feel free to shit on it too if it could help me fix it.

The material is made of an electrostatic resin that absorbs impacts and turns it into potential energy. This energy is slowly released as current as the suit used quantumn fluctuations between atoms to power nanomachines. The fibres act as a whole to spread as much of the energy out and redeliver an impact as force.
>>
>>9134784
yeah there are spiral nanoparticles reeled up inside the material
and when you punch it, they unfold, and hit back
but they unfold not only to the outside, but also partially in the inside, but this is absorbed and converted into usable energy

I'm hoping to return to college and do a second degree in math/a math related subject (ideally Computer Science). Unfortunately, I haven't done math in well over a decade, and when I did math previously it wasn't exactly the highest level math.
Can anyone recommend how I can best learn/re-learn/catch up to college level math and be ready and prepared?

Medical school is for brainlets that were too retarded for biology.

>>9134355
I don't think that's necessarily true, but I do believe biology REQUIRES a lot more abstract and critical thought- though people in med school can have those qualities, and it makes for good doctors. Recent trends however have been pure memorization to grind through it, and cheating in order to get the paycheck so asian parents don't disown you.

lmao no medicine is straight memorization at every level you just have to grind forever
An average of twelve car accidents happen every minute; about six-thousand teenagers are killed in car accidents every year in the US. About four million people are bitten by dogs.
Why is the number about the same every year?

It probably isn't. You need variance (or standard deviation) in addition to average to make such a claim.

Hey /sci/, I'm having a bit of an issue with a problem I am trying to tackle.
So, I've found myself an expression for a term Tn in a sequence of numbers, which is given by (4^(n-2))/256 -(1/2)Tn-1
That is, for any given term in the series, it relies on the term before it for an exact answer.
This is for all n as part of the natural numbers.
How would I go about figuring out an infinite sum in terms of only n. (I.e, how do I define Tn without Tn-1)
>inb4 op is a faggot, we're not your homework helpers
Fuck you I cant find shit about this on the internet.
