    LaTeX Latex howto

    i've been away more than 5 yrs and can't find the thread that used to tell you how to code latex. you could practise there too without burdening others with your errors. where is that thread? or something similar? in friendship, prad

    Human population

    ok it seems there is no doubt about the growth so the stuff about the 'myth' is likely the biggest myth. however, how is it that the growth rate is declining? in both graphs, there is a tendency for decreasing slope d^2P/dt^2 < 0 i can see it argued that in europe it will decline because...

    Human population

    i've always been told that the human pop has been going steadily up and up (6E9 in 1999 i think). a site like this http://www.populationaction.org/ seems to support this. now someone has told me this is all a lie by the elite to kill off large segments of the world. ok that's fine - i have no...

    Parker 61 fountain pen

    well palladin, it's not that it couldn't be said, it's that it doesn't happen at least for this pen which i think works on capillary action. the exact opposite happens as i outlined. i think it could be the way you state it though for a squeeze or cartridge fountain pen and definitely for a...

    Parker 61 fountain pen

    pallidin, i agree with you and apologize for causing this confusion. i wrote "i keep the pen rightside up (the way you'd carry it on the clip in your pocket)" and it wasn't sufficiently clear especially since pens do have clips in various places though i have never seen a fountain pen that is...

    Parker 61 fountain pen

    we just have a discrepancy regarding interpretation of orientation. let me rephrase it. if the nib is pointing down, i would think gravity would pull the ink towards the nib - which it doesn't seem to be succeeding in doing if we just leave the pen lying around with the nib pointing down...

    Parker 61 fountain pen

    i meant just towards the nib, pallidin. presumably with an upside down pen, gravity would pull the ink towards the nib which it does for regular fountain pens and ball points (which don't write too well when the nib is pointing up). in friendship, prad

    Parker 61 fountain pen

    this is a unique fountain pen from the 60s in that you don't squeeze anything to get ink into it. you just dip the solid one piece 'cartridge' into the ink and it fills, presumably through capillary action - i don't know what's inside, but i doubt if it is a sponge to have lasted all these...

    Moral dilemma

    geometrick, you don't need to read atlas shugged (it's a big fat book anyway and unlikely to enhance your understanding of math or physics). you merely need to understand that there are many ways to give back and that you don't have to work in the social justice arena to contribute to it. in...

    Calculus final in 24 hours - failure imminent - need some advice

    greenneub, failing it may not be a bad thing if you don't really understand what you are doing. i recall i didn't attend most of my 1st year calculus classes, but crammed and studied specific areas which just happened to show up on the exam. i pulled off a 75% for the whole course. however, i...

    Philosophy: Should we eat meat?

    (been away for a week and putting in a very brief appearence for now.) it is precisely for the health benefits to the mother and the baby that people adopt veg diets (just as my wife did!) all this morality stuff aside, it is important to understand that not only can one maintain weight...

    oh dear :frown: i think my physics needs more help than i realized if i have forgotten this sort of thing. :redface: thank you for explaining all this, Gokul.

    Philosophy: Should we eat meat?

    "athletes need meat" is one of those silly ideas that still occasionally rears its ridiculous head .... well, i suppose since some athletes do use steroids and stuff, they will find a suitable source of those sorts of things in meat etc. :rofl: some people are still under the weird...

    Philosophy: Should we eat meat?

    thanks for clarifying this francis. if you "treat every animal great and can kill it painlessly", you may not get any objections from the utilitarian faction provided their premise is to minimize suffering. (note: that since this doesn't really happen, it is as you say merely "an exercise")...

    Very Wierd Physics

    ok thanks for the explanation - it makes sense. but wouldn't the absence of friction decrease the decelerating force and therefore create an acceleration? what about a curling stone that you slide over a carpet that is on an ice rink. what will happen when the rock hits the edge of the carpet...

    Philosophy: Should we eat meat?

    i agree! other than a few minor outbursts this is one of the best threads on this sort of topic i've seen for quite some time. i think that as different people come into the thread, they make different contributions. i think it is best to see a forum thread as a conversation at an openhouse...

    Very Wierd Physics

    but wouldn't the real issue be friction? say the total energy of the system is given by E_{Total} = E_{kinetic} - E_{friction} the frictional energy is negative because it is going out of the system. now if by applying the brakes we cause skidding and thereby reduce the frictional...

    Philosophy: Should we eat meat?

    so i don't get what you are complaining about then. if a veg makes a choice to protest against others eating meat, what's wrong with that? that veg has made a choice and since you apparently don't want to infringe on another's choice (for whatever reason), just what are you complaining about...

    Very Wierd Physics

    hey! that's a good point! in fact, that is the point since the force that does exist is that of friction. even though we have less friction by the application of the brakes there is presumably no force being applied by the locomotive when the brakes are on. so what does that leave us with? it...

    Physics and musical instruments

    that's great! my physics is pretty rusty and this seems like a great way to get the debris off. we have recently become very interested in music and have acquired several instruments to play with and upon. neat stuff!! my first computer was a kim1, but i did nothing as elaborate as you. that...

    Very Wierd Physics

    so what you are saying is that when the brakes hit the friction is reduced because of the wet tracks - ie the sliding friction is less than the rolling friction. it isn't that a force is added, but the frictional force is reduced so there is a net increase in force, hence the acceleration. is...

    Physics and musical instruments

    i've been looking at my sciam book and i was just wondering if there are some people who want to look into the topic of the physics of music in a more extensive way. if so, i can present parts of what i read from the sciam in this thread and others can elaborate on the ideas or just ask...

    Philosophy: Should we eat meat?

    i think the reason some veg (not so much the ethical or the enviro veggies) say "Yeah, we always knew meat was bad for you", is because they read about the links meat-eating seems to have to Heart Disease, Hypertension, Diabetes, Osteoporosis, Cancer etc. these links are demonstrated often...

    Philosophy: Should we eat meat?

    i understand completely and appreciate your clarification. and you are welcome for your thank you! i'm relieved that you were not trying to apply that particular "right to life" argument to vegetables. this is a good question and i'm not sure there will be widespread agreement here. for...

    Philosophy: Should we eat meat?

    that's no problem! it will give us something to talk about! this is a good thread with nice people generally who usually make an effort to respond with sincere effort regardless of the position they hold. i hope you will enjoy your stay here. The small intestine measures approximately 23...

    Philosophy: Should we eat meat?

    ya i didn't see it because you had posted it to sheepdog in post #1111. well at least that's a start. but everything doesn't hinge on whether the organism is given this right not to be killed. some of it seems to hinge on our certainty as well. well it can be called anthropomorphic, but that...

    Philosophy: Should we eat meat?

    i'm not asking you to 'trust' me, loseyourname. however, it is completely incorrect to say that a veg diet needs supplementation as though it is somehow deficient in comparison to the meaters diet. if you want to find out about veg diets, you should ask people who are involved with veg diets...

    Philosophy: Should we eat meat?

    there are no consequences that are a result of eating a strictly vegetarian diet - but if one is really worried you can always use all the supplements that have been around since the 50s for meaters. also, the hormones aren't really the only problem with colon cancer. for instance, some of...

    Philosophy: Should we eat meat?

    actually it is all three of these and more! but we should probably stick to the moral issue here since this thread is in value theory. however, if you want to explore some of the other ideas you have posted and are interested in the 'otherside', please just ask. no one needs to eat meat to...

    Philosophy: Should we eat meat?

    it is absurd and i certainly haven't seen anything that bizarre here, but i have come across it more than once in the past. one such instance during the 90s (i think) was in a book called "Living as if the God in All Life Mattered" by a meater gone veg gone meater. she said things like the...
