<0> I take it yo don't know what significant figures are then...
<1> not fraction
<1> we are not speak of fraction, but whole numbers
<1> yes I do I learned in physic
<1> 5 is a whole number
<2> Two -- he should be in jail -- multiple charges - but ehh he's a Kennedy... and we the people did not have INSTANT access to stuff
<0> Then you'd know that 5 * 5 = 30
<0> Doesn't matter
<0> it has only one significant figure
<1> P_O: is five a whole number
<3> then what's 5+4
<1> 9
<2> five what and four what?
<3> P_O do you concur
<3> ?
<1> are we speaking in bussiness math
<0> US-Male, 54 obv.
<3> haha
<4> http://en.wikipedia.org/wiki/Mary_Jo_Kopechne
<3> no, +
<3> 5+4
<1> hahah
<1> anyways in real scince you don't use much scinftic figures
<0> US-Male, 5+4 in which context?
<2> five C sugar and 4 C water would get you four C of very good syrup
<1> P_O: you use excat number
<3> P_O: real numbers
<0> gop, er, what?
<1> P_O: in calculus you learn excat figures
<3> not strings
<1> that is excact numbers
<1> useing some calculus equation
<1> or concept
<1> like finding the exact area under a curve
<1> not just a eyeball answer
<3> lol
<3> I forgot that one
<0> gop, is excat a typo for exact?
<3> some people do that, other's don't
<5> but its ***inine to claim "significant figure" in such a manner
<0> Lupine, I wasn't tought that.
<0> *taught
<0> however you spell
<0> :P
<3> one should really use scientific notation in those cases, to specifiy the # of sig figs
<0> I was taught to round up.
<1> P_O: if you 5 rows of apple and 5 collums of apple, how much apples do you have ?
<6> AP - The prospect of higher energy prices should not stop the world from imposing sanctions against oil-rich Iran, U.S. senators said Sunday.
<6> time to invest in oil
<0> gop, 25.
<1> that my point
<1> good point
<5> US: right :-)
<3> P_O: so what's 5+4 =) ?
<0> There's an exception to sig figs for things that you count.
<0> But that doesn't mean that whole numbers themselves are exempted
<0> US-Male, 9?
<3> yes
<3> tomorrow we do fractions!
<1> lol
<3> ok break time
<1> what sig fig used for
<1> I learned in physic
<1> but I forget, or didn't care much
<0> Sig figs are used in any measurement.
<1> oh yea I Forget
<1> but I never used them in a calculus course
<1> we delt with exact figures
<1> like velcoity
<4> http://foia.fbi.gov/chappaquid****/chappaquid****_pt02.pdf <== FBI FOI file online
<1> veleocity and accelartion
<0> Lupine, what's the reasoning behind that evens/odds rule?
<0> That makes no sense.
<1> HMMM
<5> p_O: oh, helping to prevent the inherent bias in the results from it
<2> hi tortus
<0> Lupine, you mean from always rounding up? or what?
<5> especially when your measurements are close to the sensitivity limit
<1> P_O: what type of mersssure do you mean, to refersh my memory
<5> p_O yea.. by always rounding up, it is uneven [ no pun intended ]
<0> Ah okay, that makes sense.
<7> hi kaliuna
<0> gop, any measurement you make sig figs apply.
<1> i forget or am confused?
<2> tortus -- did you watch 24?
<1> Kaliuna: I saw it
<1> what a great show
<0> gop, ever taken chemistry?
<5> in any event, one rarely rounds or applies significant figures until the final/full calculation
<1> they killed the black preisdent
<1> ex
<2> yup and its only gonna get better
<3> double rounding is a sin
<4> that lists the various perjuries that Kennedy was convicted of
<5> compounding sig figs or compounding rounding really fubars you
<2> GOP -- don't give it away - some people may not have seen it
<1> Kaliuna: the best drama show on tv I seen in long time
<1> oh west coast feed
<2> gop - well yup
<7> kal: no, what is it?
<0> Lupine, most of my use of it is in a HS chem setting, so all of our calculations are pretty simple.
<2> it has definitely improved from first years
<1> like if I say 2.5 inches
<8> ROFL ........TEHRAN, Iran -- Iran, whose president has denied the Holocaust, said Sunday it would hold a conference to examine the scientific evidence concerning Nazi Germany's extermination of 6 million Jews. Hard-line Iranian President Mahmoud Ahmadinejad has recently provoked global condemnation for saying the Holocaust is a "myth" and calling for Israel to be wiped from the face of the earth...
<2> tortus -- high crime and drama --
<1> I can just say 2 inches
<1> to make the rounding better
<8> yep..hold a conference
<1> or if it 2.7 i can just say 3
<8> that'll straighten it out
<0> gop, no.
<7> i watched a movie, layer cake
<2> two -- ayup just what we need...
<0> It's used when you calculate based on the measurements you take.
<1> see physic is not my thing
<3> gop owes me $92 but let's round it to an even $100
<1> US-Male: oh intrest
<2> tortus - ahh well its a decent show - and this season premiere -- oh ya... gonna get even better
<1> of 8 usd
<3> ok we can call it interest
<8> PO owes me 5 bucks, but let's round it out to a hundred.
<7> kal: i don't have cable
<1> Twobar: lol
<8> an even hundred
<5> p_O: also, in more complicated caluclations.. you have to take into account the significance of each term
<2> tortus -- ahh its not ON cable - just on FOX -- and there are regular tv FOX stations :)
<7> kal: what happened in the show?
<1> Lupine: in "lay men" terms, what whould a computer network guru need such information
<1> Kaliuna: they should replay on fox news
<8> behind THEE
<1> or fx
<2> tortus -- would tell you, but people in west coast might not have seen it yet...
<7> must have been pretty good then
<8> "CALL ME ISHMAEL"
<2> gop -- ehh tomorrow night is part two...
<5> gop: well, in that case.. the issue of single versus double precision numbers probably is more important
<1> I just hated that computer secene so fake
<8> I bet liberals dont know what that is
<7> ISHMAEL, evenin
<0> gop, like for example, in a density calculation, if you measure out 100. g and a density of 1000. mL your density is going to be .100g/mL
<8> tortus, that's the opening line of "Moby ****"
<7> ya mate
<8> aye, matey
<3> you can do error analysis using the partial derivatives of each term in an equation, with respect to each variable
<2> tortus -- yes it was good!!
<1> Kaliuna: oh wow I will watch
<9> Layer Cake was pretty good.
<8> nice bag o fruit
<3> if you want to go to the trouble
