Prometheus

I remember spending a lot of my childhood playing games, talking about games and trying to get money to buys games. It was awesome.

I don't follow. What do you ultimately want to do? Standardisation has several meanings between maths, statistics and science: from the context i'm guessing you mean standard score? If so this is easy in R. What have you tried so far?

The implications are all based on the assumption that procrastination results in a stress response when deadlines loom. If you don't stress out when deadlines loom or don't have deadlines you won't suffer. Pick your job to suit your personality and you should be fine.

At a quick glance it looks interesting - but i couldn't get past the irony of reading about wasting time while procrastinating from my own work. Hopefully i'll get time to take a closer look, but i would say that it might be more prudent to ask whether your model is useful rather than correct. It's my experience that these types of models don't represent some fundamental aspect of reality (as do many models in physics), but just try to usefully capture some aspect of our world.

A metal cylinder surrounded by a tube of LIH material surrounded by another metal tube. I need to find the free charge per unit length on the inner cylinder. It's described as long, which so far in the course has always been an invitation to assume it's infinitely long.

I need to find the free charge per unit length, λ, on a cylinder which is surrounded by a LIH dielectric material (which itself is encased by another tube). I've already found the electrostatic potential V® from which i've found E. From this i can find D easily as D= εε0E. Then i use this integral version of Gauss's law: [math]\int_S[/math] D.dS=Qf. Using the cylindrical symmetry of the situation i get: Dr2πrL = Qf Then i just plug in my values and get an answer. The question is what am i missing? The question is worth a barrel of marks and the above seems too simple. I've deliberately omitted details as i just want a nudge in the right direction, but can supply them if needed. As always, all help greatly appreciated.

So i don't understand why someone who wishes to save the mortal souls of people would engage in behaviour they know will get them banned. Who learns from that? These are not the actions of someone who genuinely cares for people, but of someone playing the martyr; one who wishes to emulate her favourite child sacrifice perhaps.

The world i'm creating is for a tabletop RPG: i need to be able to narrate the story on the fly. I'm thinking by creating quite a detailed world that when someone does something unexpected i will be better prepared to improvise. Who knows when someone might want to plan some elaborate naval attack involving complicated tides. But, like you say, i don't want to think about it too much - this thread represents pretty much everything i have on the celestial mechanics of the world at the moment.

We need only three things for evolution to occur: Something replicates. That replication is imperfect. Selective pressures act on the replicates, changing their chance of further replicating. Any system with these three properties should be subject to evolution, not just biological systems, Hence i would say it's theoretically possible. However, i'm not sure what evidence for memes would look like (as we enter the woolly world of sociology/psychology).

Yes, but none of it is static. India has been recoiling from some high profile rape cases and women are finding a voice. Attitudes are shifting.It takes time - sometime millennia apparently. We are old enough as a species now to do away with 'because sky daddy told us' ethics. If we imagine there is a configuration of the world that maximises the sum of suffering among all beings then any other configuration is preferable. Morality can be the attempt to shift to a configuration with less suffering. Take this as your universal if you like, but it's something humans have created. P.S. I wouldn't consider arranged marriage abhorrent myself: only certain incarnations of it. When done well it is essentially families playing match-maker, asking their sons and daughters whether this is good match or that one is a good match etc...

Here's my take. For sure what was considered normal at some point is now thought abhorrent. Take the example of a women being forced to marry at some lord's whim. It has changed only because certain women and men weaved a narrative (like explaining how horrible it is on the receiving end): it didn't just change in a vacuum. And now that narrative is part of our history and culture, one we should not forget. The narrative of womens' liberation is still being written today; something we are all participating in (to lesser or greater extents). That our sense of ethics changes and develops is no bad thing.Things like justice and mercy are not things inherent to the universe but rather what humans bring to the universe. If we want justice in the world, we are the only ones who can create it. I'll paraphrase Inow: ethics is less an act of discovery and more an act of authorship.

I came across a similar study (also forget where) in which some kind of primate was punished for opening a box or some such. A newly introduced monkey was stopped from opening the same box by the old monkey. And so on they added monkeys all being stopped from investigating the box, but they also took out the first monkeys so that there were none there that had actually experienced the punishment. Interestingly, and if i'm remembering correctly, some of the monkeys were quite violent when encouraging new monkeys not to open the box.

First, i'd like to agree to agree with ajb that the study of the supernatural (more precisely the myths surrounding it) is fascinating and can tell us a lot about the human condition. In terms of the evolution of religiosity, two points: There is an assumption that an evolved trait is beneficial, but it's enough that the trait is not detrimental to survival. Religion is being treated as a homogeneous concept but even today we could could be talking about several different concepts. I imagine the differences were more pronounced in earlier times.

Then i'm reporting the obviously psychotic Father to child services.

I was looking at all of them - some 35000. Used a python script to extract all the parameters. I presumed there was just some truncation error when extracting the data but since i know nothing of MM kinetics i just wanted to confirm it has no physical meaning. I'm satisfied now it is just truncation error. Thanks for the help.

By what metric can we measure perfection?

I don't know about that particular example, but generally the Chinese concept of gods and heaven is not directly comparable to the Abrahamic concepts. The mythos is more working in union with the way of Heaven to achieve something on Earth, as opposed to strictly following the law set down by a God. You can work against the way of Heaven, but you'll likely find it difficult even if the gods don't directly try to hinder you. Although i'm finding understanding Confucian thought a little difficult, so i could be wrong (but i married into a Confucian family so gotta keep trying). What is the same is that people interested in power-mongering will use religion to meet their ends.

And that's another interesting parallel: Pandora, the first woman, was given to man as part of that punishment. Hence both traditions cast women as the temptresses that divert men. I've heard that Islam places equal blame on Eve and Adam in the Fall myth as opposed to the Christian myth which emphasises Eve sinned first (in Paradise Lost Milton has Adam nobly eat the apple just so Eve won't be alone in her punishment). And because we're also talking Buddhism (still don't know why though): the Buddha was asked by his aunt to accept her into the sangha. He refused three times and only acquiesced after his right hand man (Ananda) basically badgered him into it, and then only if women followed additional rules. The Buddha admits it's just as possible for a woman to attain enlightenment and his initial reluctance is never really explained as far as i know.

The derivation i followed was similar, but for one bit. From the steady-state approximation: k-1[ES] + kcat[ES] = k1[E] and: Km = (k-1 + kcat)/k1 we get:[ES] = [E]/Km Which is why i thought Km could not be zero for the MM to be valid.

I've always liked the contrast between the story of the fall of man and the Promethean myth (does it show?). Both can be interpreted as attempts to godhood. In the former Eve and Adam eat the forbidden fruit so that they may know good and evil, as do the gods : In the latter myth Prometheus awards mankind the fire of the Olympian gods (i.e. the knowledge of the gods) which pisses off Zeus. I find it interesting that in one myth the challenge to the One True God is an excessively punished mortal sin, while in the other myth the challenge to the strongest god is seen as a boon to mankind. One tradition demands repentance the other rebellion.

In addition to that you have to divide through by Km at some point deriving the Michaelis-Menten equation, which if zero would be undefined. I ask because the BRENDA database has some Km (and Kcat, Kcat/Km) values of zero and before i wrote it off as truncation or experimental error i just wanted to check if it made any sense.

I've been looking at the Michaelis-Menten constant, Km, being zero from a mathematical perspective and it doesn't make any sense - i.e. it breaks the Michaelis-Menten equation (the velocity of a reaction becomes undefined). But does having a Km=0 make any physical sense? Is it possible - does the model need amending to take into account zero values? Thanks for any insight.

True, but i think i will just limit this to about 4-5 times per year. Now just have to consider the impact the three moons would have on the planet...

If anything Buddhism developed in the context of severe ascetic practices what would become Hinduism: it was a change from asceticism to compassion. I'm not sure how much Greek thought influenced the early development of the Abrahamic faiths, my understanding is that traditions like Zoroastrianism had more influence. Perhaps Hammurabi's codes of law also influenced their development? Not sure, but I would treat the Abrahamic faiths separately to the Vedic faiths.

I'm thinking of having no axial tilt , with seasons due to the elliptical orbit. I also imagine that the seasonal variations could be exacerbated by how many suns there are visible in the sky at the time of aphelion or perihelion. If there is only one sun visible during the aphelion then it would be a particularly harsh winter over the entire world. I imagine this would particularly motivate civilisations at high latitudes to study celestial mechanics to predict the coming of these harsh winters. I briefly considered this but i thought it would create life and civilisations too different from that on Earth for the setting i want.
