I don't know how many people have both the expertise and interest (I know I lack the former) to discuss this, but I found this proposed explanation for the internationally observed reduction in violent crime intriguing. The theory goes that the elimination of lead in petrol and household products closely corresponds to reduced crime everywhere you look.

If there's a refutation accessible to the layman that would be interesting too.

The lead argument is based on the straightforward correlation between IQ and criminality - people with lower IQs are more likely to commit crime, lead toxicity lowers IQ, therefore lead toxicity may cause crime. It's a fairly loose chain of causation, but perfectly plausible on face value.

>people with lower IQs are more likely to commit crime, lead toxicity lowers IQ, therefore lead toxicity may cause crime.

IQ is not a proper measure of how intelligent you can potentially be but rather a measure of how educated you are, which means that people with lower IQ tend to be from impoverished backgrounds. The same 95 IQ chav could have been a 120 if he had been born into a richer family. So the argument now goes:

>People from poor and anti-educational backgrounds tend to have a lower IQ, people with lower IQs are more likely to commit crime, lead toxicity lowers IQ, therefore lead toxicity may cause crime.

Which doesn't really make too much sense. In fact I'd argue that lead is irrelevant to crime, and it's a matter of a good solid education for all.

>IQ is not a proper measure of how intelligent you can potentially be but rather a measure of how educated you are

This is arguably untrue. Correctly managed IQ tests compose two papers (really big puzzle books, essentially), one of which is variety of logical and numerical problems, the other of shape and pattern-based problems (to measure basic cognition and offset such bias). As long as the subject is capable of reading and completing these, education should not be a limit on achieving a respectable score.

>People from poor and anti-educational backgrounds tend to have a lower IQ, people with lower IQs are more likely to commit crime, lead toxicity lowers IQ, therefore lead toxicity may cause crime.

>Which doesn't really make too much sense. In fact I'd argue that lead is irrelevant to crime, and it's a matter of a good solid education for all.

Wealth is linked to diet and nutrition, which in turn is linked to intelligence.

It is also arguable that people who would score low in both logical and cognitive tests are treated differently by society, have fewer opportunities (or are oblivious to those that exist), and perceive the world accordingly. They are also more likely to be caught having committed an offence. If exposure to lead reduces intelligence by a significant degree then a correlation may exist.

That's not true in the least, and I'd suggest you go and find out what an IQ test actually is because you appear to be severely misinformed. As >>3609 describes, a correctly composed IQ test assesses abstract reasoning and requires no prior knowledge.

While it is true that environmental influences can affect IQ, the effect is relatively weak, as demonstrated in numerous twins studies over the years. Education is far less significant than adequate nutrition and good parental interaction. Events like toxic exposure and head injury can drastically reduce IQ. The predominant influence on IQ is heredity.

Your second statement is clearly a nonsense, predisposed upon the fallacious idea that IQ is purely a measure of educational attainment.

Well, I've tried to understand, with difficulty, what the study says. The X/A ratio is to do with X chromosomes and autosomes (non-sex chromosomes). "Because two-thirds of X chromosomes are found in females whereas autosomes are split equally between the two sexes, a ratio between their effective population sizes (X/A ratio) of 0.75 is expected under random mating." So the higher the ratio, the more Xs, and the more reproducing females there are in the population. The graph is captioned "The low X/A ratio for the European has been suggested to be due to demographic effects connected to migrating out of Africa", which presumably means something caused there to be less females, or less reproducing females, in the population. So that's all it means. Ancestral genetics show less women had babies in Europe than Africa. Or something.

Crack is the freebase form of cocaine, as opposed to the hydrochloride salt. Reacting cocaine hydrochloride with a weak base (usually sodium bicarbonate (NaHCO3)) removes the hydrogen and chlorine ions, giving the freebase cocaine alkaloid, water, carbon dioxide and a salt (sodium chloride in the case of a reaction with sodium bicarbonate).

The freebase form has a much lower melting point, allowing crack to be smoked - cocaine HCl would just burn. The effects are essentially the same, but smoked crack enters the bloodstream much more quickly than snorted cocaine (due to the much greater surface area of the lungs vs the mucous membranes) giving a more intense and immediate hit. Crack cocaine isn't water soluble, so can't be effectively snorted.

Heroin offers an interesting parallel. The overwhelming majority of heroin sold in Europe is in the freebase form, which can be readily smoked but needs to be buffered with an acid (usually citric or Vit C) in order to be dissolved and injected. In the US, the market is split - on the east coast, most heroin is sold as a salt, whereas on the west coast it is usually sold as a freebase.

Also, that minge haunts my dreams, like a stubbly Eye of Sauron.

3493 I have a tenuous theory.
So, laughter.
Sex and orgasms are pleasurable because they're important for procreation (and perhaps pair-bonding). Food is pleasurable too, in a not dissimilar way. In fact most things that our bodies need to function and recreate optimally are pleasurable (ignoring things like salts and sugars which we enjoy too much, due to their scarcity of availability for aeons but over-abundance now).
Animals enjoy those things too. But most animals don't laugh. The only animals which display a sense of humour (as far as I know) are some varieties of non-human primates, dogs, elephants and possibly dolphins. These are all pretty smart animals with the capability to develop complex social structures.
The tl;dr of it all is do you think laughter [could be said to be] the social/group bonding equivalent of an orgasm? It's a natural rush we (usually) get from communicating with each other. There's no other obvious explanation for it that I'm aware of.

As >>3496 says, that study is related to the very 'theory' you're proposing. In fact, all of the other examples of reinforcing behaviours you cite in your first post are either wholly or very strongly effected by the dopamine reward pathway. Pretty much everything that encourages us to do anything is; be that eating food, having sex or taking drugs.

Am I right in thinking that all living beings are light's energy in a different form?

Plants grow via photosynthesis, buy converting the energy from light into fuel. And animals then eat plants, converting the energy from plants into fuel etc.

Is anything added to the conversion? Or are all living beings light's energy?

Well that's all a bit philosophical and semantic really. Personally I would say that yes, it's surely pretty clear that life isn't separate from the universe. How could it be? It exists and is spawned within it.
I'd also agree that it's fair to say it's an extension of it, but when you get into words like "expression" it starts to muddy the waters a bit and maybe implies some sort of underlying consciousness or will. Maybe you didn't mean that at all though which is why I mentioned the semantic aspect of it.

I do think it's quite a nice way to look at things though, that we are the universes sense organs, a way for it to perceive itself etc etc. That is all pretty well trodden metaphysical ground though, even Bill Hicks had a bloody bit about it.

Anyway, I'm sure there are probably some more rationally minded materialist scientifically inclined headbods who would take issue with that line of thinking.
For myself I think it's a nice way to look at things but it's easy to fall into lazy new age thinking that way and I'm inclined to always keep a sceptical eye on my own thought processes. I think when you get into these sorts of areas then they're not really scientific questions anyway.

Would like to hear other people's perspectives though. Sorry for the ramble, I've had a glass of red and a valium.

Recently an American politician has enraged people after claiming that a woman couldn't get pregnant from a real rape because her reproductive system would shut down if the rape was "legitimate", in his own words.

This idea isn't actually as dumb as it sounds. Why do women conceive from rape? If rape is that damaging to a woman's reproductive success by taking away her choice, why haven't they evolved some way to prevent conception from happening from rape?

Apologies for what may seem like an extraordinarily trite subject to such boffins, but I am looking for some enlightened discussion.

The thought occurred to me a while ago that if (and I am aware that in terms of realism, it's a very slim prospect) humanity ever does reach out and colonise the stars, what will the implication be on the development, progression, and continued survival of the human race? And what are our most likely means of achieving it?

To begin with, as I followed this train of thought, I was somewhat fascinated by how primitive our early space-faring voyages will appear to this hypothetical future Alpha Centauri society. It seems inevitable that things will parallel the early colonisation and exploration of the new world by medieval humans. Early colonists will most likely be entirely cut-off from the established human race, the vast gulf of space making even basic communication difficult, meaning the society of our new worlds will be something almost alien in itself.

My line of reasoning here is that once humanity has mastered interplanetary travel within our home system, and maybe put a foothold on Mars or some distant moon of Jupiter, our attention will turn pretty swiftly to inter-stellar travel. We have always been a species to make daring, bold leaps into the unknown, and merely colonising this solar system is not enough to ensure our survival. Once we can travel between stars we will be almost inextinguishable, though we may mutate and evolve over the centuries we will always survive provided our fate is not tied to one solitary rock. But what I really want to discuss is the myriad of possibilities the future holds in such a scenario. Hypothetically, if we managed it, how would it work out? What do you think will become of us?

Will we wage vast interplanetary civil wars over resources and territory, the new Martian global elite leaving the paupers of Terra to starve and fight amongst themselves for what little fossil fuel remains? Will the great exodus fleet of varying corporate, government and military alliances survive it's expedition across space with some kind of cryogenic travel, or will the eventual survivors who set foot on New Earth be unrecognisable? A tribe of religious zealots worshipping the technology and ideology of a bygone age, having been confined for dozens of generations aboard their mothership, the nations of our new home forming eventually from these fractured remnants of ancient Earth society? Would they even still have mastery of the technology they used to travel there?

Please, discuss. I'll let you in on the secret that I'm thinking of starting to write a hard sci-fi novel and I'd like some input from people who actually know science, rather than just my mild acid-trip imaginings.

The views of an uneducated lower-classian like myself would go thus - The only groups able to fund such exploration will no doubt be corporations and, because of this, the first expeditions will have such emblems as 'the golden arches' painted onto the colony ship hulls.
After securing their new worlds and the bountiful resources found upon them, the now 'mega-corporations' will turn on one another in the name of profits.

3434 Dynamometer
A very general question; open to all discussion, is about to be asked.

Is there a way to create a (chassis / engine / etc.) dynamometer that measures the power of a vehicle in nodes instead of a one off reading.

When I say nodes I mean, by applying a known load to a fixed speed and returning it to the previous... e.g.

10 hz -> 0 hz say takes a load of 10N
20hz -> 10 hz say takes another 15N

and from this you map the engine power by knowing the amount of energy required to decrease the speed to the previous node.

Any help would be greatfull.

I have a very nice mechanical pencil, however the lead has jammed and I'd like to get it out. The mechanism is enclosed in a stainless steel case that I can't open without breaking the pencil.

I have tried a couple of ways to get it out, using metal wire to dislodge the lead and heating the pen to expand the metal, but it's not worked.

I've come to /lab/ to ask: Is there anything that would break down the graphite inside this pencil without damaging the case or the mechanism? Is there anything else I can use to salvage the pen?

I take a lot of public transport and I sometimes try to imagine what might make pedestrian routes nicer/safer.

I've noticed a lot of places with poorly designated pedestrian routes, particularly alongside A roads and the like, those awkward areas where countryside has been sliced by traffic. My most recent idea was, rather than railings, what if these routes had a simple separator made from biodegradable plastic? I'm trying to imagine materials which might absorb CO2 emissions from vehicles as they drive by, also. Carbon dioxide scrubbers? Perhaps they could be intergrated?

Also, if the aesthetic doesn't appeal, perhaps they could be trellis-like, with plants grown throughout.

I just thought a simple dividing border like this could be useful as an indicator, ecologically sound, and hopefully quite cheap. Someone please feel free to tell me my idea is stupid.

The "railings" in the middle of a dual-carriageway are specially designed safety barriers that do a very complex job. They are there to prevent vehicles from crossing over into the other carriageway (to prevent head-on crashes). They need to be flexible enough to cushion the impact, but not so flexible that they catapult cars out into the inside lane. They also have to deal with a huge range of vehicle weights, from a 700kg smart car to a 44 tonne lorry. The design of these barriers is a constant work in progress and they are a crucial safety technology.

The better solution for pedestrians is segregation - providing alternative paths that are protected from traffic and noise. Walking alongside a busy arterial road is never going to be pleasant, but it's usually quite easy to design pedestrian routes that are separated from that traffic. Where you have pedestrians interfacing with dual carriageways you have a fairly costly engineering challenge to provide crossings (bridges and underpasses don't come cheap) so you generally want to keep pedestrians away from such routes.

I didn't mean so much the barriers in the center, but rather guard rails like the ones pictured (which are usually only placed along specific stretches of road).

Those barriers exist mainly to route pedestrians towards safe crossing points. Their design is less complex than a median barrier, but they're still built to provide the greatest possible energy absorption in the event of a vehicle impact, protecting both motorists and pedestrians. The design of these barriers is prescribed in British Standard 3049 - much more thought has gone into their design than you might imagine.

The use of pedestrian barriers at all is a hotly disputed topic amongst planners and traffic engineers. In many circumstances, the use of barriers reduces the visibility of pedestrians to motorists, which can dramatically increase the risk of accidents. Guardrails can be almost completely opaque at some angles, which poses an especially serious risk to children. Any design that worsens the visibility problem is a complete non-starter, as most new guardrail designs are specifically optimised to improve visibility.

There might be a case for transparent polycarbonate barriers, but these would have several downsides - less energy absorption in the event of a crash, higher cost, lower durability and greater vulnerability to vandalism.

Thanks for this. I'm not a motorist nor an engineer, so perhaps I shouldn't venture like this, but I do think that perhaps there's an argument to be made for visibility over the aptitude of the materials, particularly in places where there's no barrier at all.

It occurs to me now that my 'trellis' idea would be bollocks, unless the plants were very low to the ground.

I also wanted to mention that I recognise the practical solution you offered in your last post, but I encountered one of those areas where segregation isn't possible today. It doesn't sound like much, but alongside certain roads even the smallest indication that pedestrians have an area where they are meant to be makes the entire experience much less alien. I remember having to cross a dual carriageway, and even a hint of tarmacked path showing the accepted route was a great comfort.

About damage and vandalism, I'd hope that the materials would be cheap enough so that the individual panel could be replaced in the event that one gets destroyed by vehicle or drawn on. I also had this idea that the barrier would be high and arched with kind of curved roofing lip at the top, but this would probably be too costly and may attract enough glare to distract drivers.

That's really interesting, thanks.

(Polite sage for adding no value to the conversation.)
