Why are most languages such shit? Just say what you need to say.
>>8676211
Because languages that aim for simple syntax like you describe usually turn out to be unweildy on more complex problems than summing the natural numbers.
Naturally there are languages that are way much better than what OP posted, but the more terse notation will still look like a programming language

Why aren't we practicing this again? Outside religious "reasoning" there is no sensible explanation why eugenics are banned.
>it's false science
Wrong.
>results would take generations
Only one generation for minor alterations such as lesser risk of hereditary diseases. Dog breeding evidence suggests no more than four generations even for larger changes.
>killing is wrong
Agreed. But abortion and preventive devices are not.
because we'd have tell people who they're allowed to fuck and which babies are allowed to live and I don't think that's legal or even possible
We are though. 90% of downs syndrom babies are aborted.
Being overzealous is a good way to end up with a retarded populous. That's what happened to china. They selected for people who could do arbitrary tests and now they're a country of cheaters.
We already are. Abortion is eugenics we've fooled bleeding hearts into accepting.
How do you think over population will effect the human race?
Asking on this board for a more thought out answer.
we've gone form 2 billion to 7.5 in about 50 years.
I think it will be a huge problem and everywhere on earth will be a crime ridden third world slum and the only people with acceptable living conditions will be governments and the ultra rich.
I think society at large will lose the ability to renew itself and technology will be forgotten when the established manufactures of complex tech goods close shop due to poor safety conditions like in chicago or detroit.
Am I being too negative?
>>8673355
bonus question.
how will the advent of human cloning effect the perception of over population?
>>8673355
it already has started affecting us anon, the arab spring was caused by the price of bread going up middle east desert places are gonna get shittier with pollution + mass population making growing food and living rough, leading to mass immigration to nice greener places like usa and europe.
basically we need a mass extinction event / plague / war
>>8673366
we aren't going to have a war because all the nations of the world are terrified of the weapon capability we have now and the capacity to completely destroy ourselves. War hasn't been war since the atom bomb fell, it's mostly business now.
The extinction event will most likely be a multi generational prolonged reverting to a dark age while some small groups hang on to advanced technology in secret.
I predict a agonizing slow and steady decline back into a new dark age that resembles the famous mouse utopia experiment.
the world ends with a whimper
I work in a chemistry lab at a top 10 public university in the US. There's 10 grad students in the lab, but it seems that only 2 of them actually genuinely enjoy chemistry and research. The rest appear to, at least, partially regret going to grad school.
/sci/, do we think half-assed science is a problem? It seems to me that these students who aren't fully interested in science would be more productive for society in a regular job. The superstar grad students that push all of the papers are working on the most pressing and interesting research anyways.
>>8672655
They are wasting space and resources. Merely attending university does not mean one is intelligent.
Stigmatizing blue collar work, and removing unions was a mistake.
Any other Color Theory majors here?
Whats your favorite color and why is it Magenta?
Some fun sciency facts on Magenta
>Magenta is an extra-spectral color, meaning that it is not found in the visible spectrum of light. Rather, it is physiologically and psychologically perceived as the mixture of red and violet/blue light, with the absence of green.
>In the RGB color system, used to create all the colors on a television or computer display, magenta is a secondary color, made by combining equal amounts of red and blue light at a high intensity. In this system, magenta is the complementary color of green, and combining green and magenta light on a black screen will create white.
>In the CMYK color model, used in color printing, it is one of the three primary colors, along with cyan and yellow, used to print all the rest of the colors. If magenta, cyan, and yellow are printed on top of each other on a page, they make black. In this model, magenta is the complementary color of green, and these two colors have the highest contrast and the greatest harmony. If combined, green and magenta ink will look dark gray or black. The magenta used in color printing, sometimes called process magenta, is a darker shade than the color used on computer screens.
>A purple hue in terms of color theory, magenta is evoked by light having less power in green wavelengths than in blue/violet and red wavelengths (complements of magenta have wavelength 500–530 nm)
>In the Munsell color system, magenta is called red–purple
>If the spectrum is wrapped to form a color wheel, magenta (additive secondary) appears midway between red and violet. Violet and red, the two components of magenta, are at opposite ends of the visible spectrum and have very different wavelengths. The additive secondary color magenta, as noted above, is made by combining violet and red light at equal intensity; it is not on the actual spectrum.
>Rather, it is physiologically and psychologically perceived as the mixture of red and violet/blue light, with the absence of green.
>physiologically and psychologically perceived

The Deniers need to be stopped
if "climate change" is so real/well-established why do the so-called "scientists" make such a big deal over any sort of skepticism? it should give them a great opportunity to strengthen/refine the key points, and all science needs to be able to hold up to questioning
>>8670012
the stakes are to high for that. questioning reality is not science it's delusion
>>8670016
and this is precisely why people don't take climate scientists seriously
Hey /sci/,
I'm dealing with a climate change skeptic who has made a claim, without peer review citation, that only 4% of the carbon in the atmosphere is from man made sources; hence showing anthropogenic global warming is incorrect. In particular, he made the claim that c13/c12 ratio from Mauna loa laboratory is only delta -8.3 ppm; the claim checked out.
My expertise lies in molecular bio, i'm having trouble finding the citations to fire back. Does anyone on /sci/ have a good review article on atmospheric carbon isotopes?
>>8668752
The claim is correct. Humans emit about 30 gigatons annually while natural sources emit about 770 gigatons. What the denier fails to mention of course is that natural sinks absorb even more CO2, 790 gigatons while humans absorb 0. So humans are responsible for all of the change in atmospheric CO2 causing warming, and would be responsible for even more without natural sinks absorbing some of our emissions.
>>8668777
I was fairly certain this is the correct answer, what ui'm looking for ais a peer reviewed article that makes the argument. I'm not a client scientist, I dont know how to read the literature.
why is he claiming that the particular value of the d13C observation is proof against climate change? the data series shows a clear downward trend indicative of more and more isotopically light CO2 entering the atmosphere.
I'm trying to get my catholic friend to concede that there is at least one circumstance in which abortion is the best option or an acceptable option - and therefore abortion itself isn't inherently wrong.
>I know there are other lines of reasoning but I went with this one.
I gave her the hypothetical situation where going through with the pregnancy would kill the child and the mother, but aborting the child would save at least the mother. On top of that you could add that the mother helps loads of people and the family rely on the mother etc etc.
Anyway, I think she just doesn't get what a fucking hypothetical question is so I want to give her a real example of a medical condition that creates this sort of circumstance.
>tl;dr: Does anyone on /sci/ know of any circumstance in which pregnancy leads to the death of the baby and mother, but abortion doesn't?
>being friends with a pro life catholic
She's never gonna sleep with you, faggot
Ectopic pregnancy.

why should this logically follow? things can still be wrong even if you have some justification for doing it

A circle isn't a series of a infinite points. A point has no length so when you add them together you will still just have a 0 length point, not a circle.
>>8676127
You're right. It's not a series of points. It's a series very of infinitely small lines connecting infinitely small points infinitesimally close to one another
>>8676129
>infinitely small lines
So zero length lines then, same thing as a point
>infinitesimally close together
So they're touching, but they can't touch because there's nothing to touch, points are 0x0x0
What you said doesn't even make sense but it still doesn't make a circle
so whats a circle then
