Why not create a charity to raise IQs in third world nations? Some leading experts say genetics account for 80% of IQ by the time you're 18. The average IQ is dropping worldwide. Would it be ethical to increase IQ through genetic engineering?

I think you have cause and effect inverted. It's not that rich people want poor people so they can apply certain economic policies, it's that certain economic policies applied by rich people cause other people to be poorer. Basically, a society where some participants believe they should get wealthier without end inevitably leads to economic inequality.

IQ is largely irrelevant to economic productivity and almost COMPLETELY irrelevant to social power; just look who we have in the White House if you're tempted to disagree (or who we MIGHT HAVE HAD, if you still do). Take a black child out of poverty and stick them in a wealthy Western household with a proper education and a diet composed of more than literal garbage, and they will grow up to be a productive adult.

That said, an IQ test measures little more than your proficiency at taking IQ tests. It was NEVER a measure of intelligence; it was a measure of educational achievement as a tool to focus on struggling schoolchildren with poor learning ability, and at best has a tenuous connection with adult intelligence except in extreme cases (like profound retardation: <20IQ). Studies have shown that people with higher IQs don't achieve more as adults but for statistically insignificant amounts.

So you could do this, sure, but nothing would change. The only thing that will is waiting for most of them to die, and then raising the living conditions up to a Western standard for the survivors. Doing it BEFORE letting them die is more humane, sure, but will probably collapse the global economy by the end of the century, likely leading to widespread war and the end of civilization. There's just too fucking many of them.

I cant' totally agree. Yes, most westerners wouldn't just breeze trough the life in the average african village. Stirling paints in Islands in The Sea of Time a vivid picture of the back-breaking work needed to grow your own crops.

Their intelligence may help them work more organized, but the raw strength is what matters. - As in all agrarian societies.

But in modern societies general intelligence (g) is more important than raw strength. And there's no link between general intelligence and industriousness (i).

I score high on g, but really low on i (just ask the tax authorities). And you can never disregard the society someone lives in.

Hello /sci/!

Yesterday when I took a walk, I saw a bunch of huge plastic containers by the roadside in a shallow natural pit.

I considered it to be a trash dump.

What kind of reasoning did I use. Deductive, inductive or abductive?

And if I used the other two kinds of reasoning, would I reach the same conclusion? And how would I use them?

There is no such thing as plastic dumpsters. They make them out of steel because plastic in that size is not structurally sound enough. Also, why would there be dumpsters on the side of the road in the first place? It still raises the same question of who put them there, and for what purpose.

All you needed to do was search "plastic dumpster" in Google Images to fact-check yourself.

>Also, why would there be dumpsters on the side of the road in the first place?
The point of a dumpster is that a garbage truck can pick it up and empty it. Garbage trucks generally drive on roads, so the logical place to put a dumpster, if it's desirable that a garbage truck can reach it, is as close to the road as possible.

>they actually do make plastic dumpsters
Color me surprised Pedantic: they have a plastic shell and steel reinforcement. And while you're technically correct, it doesn't change that those that I saw are smaller containers, generally for household rather than commercial/industrial use. Most people do not BUY dumpsters; they rent them from the garbage company who picks up the garbage from them on a set schedule, and those dumpsters ARE made of steel. 99% of the dumpsters you're going to see are made of metal; personally I've never seen one of these plastic ones. You're begging to put holes in the fucking thing because people throw concrete chunks and shit in there.

I'm sure there's some retard online out there selling dumpsters made of wood or who has made one of papier mache as an art project. But that changes nothing. OP never stated "dumpsters" to begin with, which would be fairly obvious given that they have a distinctive shape. So one could conclude these "containers" likely were not dumpster-shaped.

>the logical place to put a dumpster, if it's desirable that a garbage truck can reach it, is as close to the road as possible
But not randomly on the side of a road where there's nothing else! There's no trash sitting around there to put IN the containers in the first place. If there were a warehouse or a restaurant right next to it, then it would make sense. But that definitely would not be a "trash dump", it would be "a little concrete pad on their property where sit the dumpsters".

Actuarial are accountants for companies, rather than for individuals. They deal with statistics, mostly, to determine what might happen with a given set of starting variables. Most visibly, actuarial tables are what these people produce for life insurance companies, so they can guess at what age you're likely to die (based on sex, height/weight, blood tests, diet, lifestyle, and increasingly: genes) and adjust your rate accordingly so that they are most likely to profit.

I have a question with regards to what I would call a particular object that enumerates the elements of a binomial coefficient. Let me explain the thing first.

Lets say I have 6 elements and I'd like to choose 4 of the stupid things. The binomial coefficient tells me that there are 15 of these groupings. I.e. these:
{{1,2,3,4},{1,2,3,5},{1,2,3,6},{1,2,4,5},{1,2,4,6},
{1,2,5,6},{1,3,4,5},{1,3,4,6},{1,3,5,6},{1,4,5,6},
{2,3,4,5},{2,3,4,6},{2,3,5,6},{2,4,5,6},{3,4,5,6}}
I would like to enumerate over these groupings; and I have an object that does.

My question then is, what would I call the thing that enumerates over those groupings?
Binomial Enumerator?

Anonymous 18/09/11(Tue)18:27 No. 16695 ID: be6f8f

The technical term for each of those "groupings" as you call them is "combination". The action of picking combinations is usually called "choosing" (e.g. 6C4 is read "6 choose 4").
So you could call the enumerator "combination enumerator", "combinator", or "chooser". I think those are all acceptable names.

File 153265890490.png - (96.72KB , 620x359 , solar-panels-australia.png )

Hey, /sci/. I'm running a simulation of solar panel efficiency and I need some way to calculate energy production from the sun's position in the sky. For example, assuming a panel that is always pointer at the sun, when the sun is closer to the horizon the panel will generate less energy than when it's high in the sky.

I'm looking for something like f(x radians) = y W/m^2.

Thanks.

Here's part of what I'm doing. Assuming a panel can rotate side to side and track the sun, but cannot rotate up and down, these are the angles of inclination of the panel for a given latitude that will yield the maximum energy production throughout the year. The problem is that this assumes that as long as you point the panel directly at the sun, you will generate the same amount of power at noon as you would just before dusk. So for example at the equator the optimal angle is predicted to be 42°, rather than something flatter. At the same time, energy production is predicted to be higher in Antarctica (99% efficiency) than at the equator (92%), which is nonsense.

Yay /sci/!

Does anyone please know of a way to determine if there's any local max and min *within a set range of X-coordinates*?

As we can see, there's a local max somwhere around -1 and a local min somwhere around 3 and none whatsoever in the range 1-2.

But how do I prove that there's no local max nor min in that range?

First, what class are you taking? What level mathematics are you looking at?
Then, what is the f(x)?

Hopefully, calculus I. Take the derivative; set f(x)'=0, solve for all x values. That proves the only time slope=0 can be at those specific points (watch out for those pesky imaginary numbers).

We could also do a differential equation, i think. It looks like we have enough information from the graph to knock one out. However, its been awhile since I did one. Id need to review some notes.

Not taking any class and don't know my level.

And what if it's f(x)=(sin 10X)+X ?

That will be a constantly increasing sin-wave with no global maximum and a lot of local maximums.

>>16682
Given a closed interval of the domain, any continuous function *necessarily* has both a global maximum and a global minimum[1], since the closed edges of the interval are candidates to being global maximum and minimum. For example f(x) = x^2 in the interval [-1; 2] has a global minimum at x = 0 and a global maximum at x = 2. However, it has no global maximum in the intervals [-1; 2) and (-1; 2). On the other hand, f(x) = 1/x has no maximum or minimum in any of those intervals.

Discontinuous functions may not have any extrema even in closed intervals. For example, f(x) = x/x + x, interval [-1; 0].

There's no general algorithm to prove that a given function has no extrema in a given range. As >>16670 mentioned, the zeroes of the derivative is a good place to start, but it doesn't end there. Some functions have extrema and are continuous but nowhere differentiable[2]. Some have extrema and are nowhere continuous[3].


As for your example of f(x) = sin(10 * x) + x:

Definition:
acos: [0, pi] -> Reals
acos(y) = the value of x such that cos(x) = y

f'(x) = 0

I’m a high school science teacher, and about 15 years ago I spent a year teaching science in Bogotá, Colombia at a private school. Rich kids, raised in Spanish and English. Great kids, in fact.

I was teaching genetics with one group and we were looking at blood types. Unlike North America, identification in Colombia includes blood type (seriously, this is a great idea for emergency situations, no idea why it isn’t here) so it’s common for people to know the blood types of their entire family. We did blood tests in class and the students were able to see that it matched up with their ID info. We then used this info with their family’s blood types to look at pedigrees.

One of the girls in the class came up to me after class with a concern. I don’t remember the exact blood types, but her parents blood types didn’t fit. Basically, there was no way her dad was her dad. I fumbled through some bullshit possibility of a mutation, but I learned my lesson - never again will I have students do blood type pedigrees with their families.

I've had something along these lines happen! Super awkward!

Was looking after a 16 year girl who needed surgery. She asked if I knew her blood type, and I explained that the blood test was being processed and we'd know in an hour or so. She asked if I could let her know, because both Mum and Dad know theirs. They both proudly add they are O+. I explain that in that case she'll either be O+ or O-, because that's genetics.

An hour later her blood group comes back as A+. I tell her this, and then the three of them proceed to ask how that's possible given what I said earlier. I avoid mentioning infidelity, and weakly suggest perhaps her parents were mistaken about their own. Turns out they weren't, and Dad storms out after calling Mum a whore. Mum follows him, and I'm left with the daughter. So... about that appendix...
