<0> indeed.
<0> Now, when did we start advertising #physics to AOL?
<1> microacg: stand by
<2> Manyfold, I have a solution, but feel free to work on it or think about it if you wish
<2> I haven't had a chance to test my solution yet
<1> i like this problem be back when i have the solution
<2> if you do it how I did it it will take a while
<2> and you won't be able to paste it into chat easily ;-)
<0> :-)
<0> wait, a corpse has a tail?!
<3> No, you see sometimes when a male body dies, certain parts remain functional for a while..
<0> ...like the nose?
<0> This needs +t :P
<1> microacg: say the bullet needs time t_1 to reach the target
<2> I can do that
<2> :D
<1> then the target will be located at X_0 + V_x1*t_1 ,Y_0 + V_y1 *t_1
<2> yes
<1> the bullet will be located at V_0 cos a *t_1 ,V_0*sin a *t_1
<1> right?
<1> when it hits the target
<1> right?
<2> uh
<1> ?
<2> looking
<2> what is a
<2> the angle?
<1> the a angle under which the gun is fired
<2> ok seems good
<4> when i read the problem correctly V_0 is given as a /join #math
<4> when i read the problem correctly V_0 is given as a vector
<4> i am back
<0> Welcome back!
<4> thanks
<4> microacg: did you check my solution so far?
<2> back
<2> 1 second
<4> now we get cos a = (X_0/t_1)/V_0 + V_x1/V_0
<2> hold on
<2> V_0 is a number
<2> like 10m/s
<2> without any indication of direction
<2> is that understood?
<2> I hope I wasn't unclear
<4> and sin a = (Y_0/t_1)/V_0 + V_x1/V_0
<2> those are from?
<2> you have an x and y coordinate
<2> one has a cos, one has a sin
<4> so a = arctan sin a/cos a problem solved
<2> so you are solving for x and y I see
<2> can you compute that
<2> my method managed to avoid using trig
<2> all I needed was P's thm
<2> but it was more tedious
<4> why avoid usind trig its simple
<2> agreed
<4> P's ????
<2> oh well both methods shoudl work
<2> Pythagoras
<2> a^2+b^2=c^2
<5> manyfold: i have question?
<0> gimor, Yes. You have a question.
<0> <.<
<5> In particle physics we often speak of something as being a singlet, doublet, triplet...etc. in SU(3), SU(2) or the 5 in SU(5)... or whatever. What do they actually mean?
<2> lol
<2> "DO I HAVE A QUESTION?"
<2> XD
<0> http://en.wikipedia.org/wiki/Singlet
<4> gimor: what is your question?
<0> Singlets frequently occur in atomic physics as one of the two ways in which the spin of two electrons can be combined; the other being a triplet. A single electron has spin 1/2, and transforms as a doublet, that is, as the fundamental representation of the rotation group SU(2). The product of two doublet representations can be decomposed into the sum of the adjoint representation (the triplet) and the trivial representation,
<0> the singlet. More prosaically, a pair of electron spins can be combined to form a state of total spin 1 and a state of spin 0.
<5> manyfold:In particle physics we often speak of something as being a singlet, doublet, triplet...etc. in SU(3), SU(2) or the 5 in SU(5)... or whatever. What do they actually mean?
<4> SU(3) is the group of 3x3 matrices with determinant 1
<5> it contains 3 matrices?
<0> 9?
<5> each matrix has det 1?
<4> gimor bring up your linear algebra skill and then ask again
<4> 3 rows 3 columns
<4> it's saturday night and i have no horny slut
<5> group contains 3 matrices?
<5> what the each matrix represent?
<5> what the matrix represent?
<4> the lagrangian is invariant under multiplication with these matrices
<4> so the group of that matrices is called the gauge group
<5> lagrange represent the state of particle motion?
<5> right?
<4> gimor watch http://claymath.msri.org/yangmill***istence.mov it's very good explained here
<5> hehe
<5> why don t want help me?
<4> i help you
<5> you know what i mean
<4> but he really explains it much better than i can
<5> please you explain
<4> gimor no you don't
<6> gimor = vhm?
<5> yes
<4> who is vhm?
<5> i m
<6> thought so... people nag in the same way
<4> should i sent him to my ignore list?
<5> yes
<4> sacarasc: is he a troll?
<6> probably not... but he is impatient
<4> gimor: watch the movie i posted
<7> gimor, are you jewish?
<8> hrm
<8> interesting question haha
<5> why?
<7> PHYSICSMASTAAA, I liked your real name
<5> danf_drc:why?
<7> gimor, I know a young jewish hid who is very demanding at times
<7> :)
<7> kid*
<9> thats kind of a weird thing to say
<9> haha
<7> gimor, are you jewish?
<5> no
<7> ok
<5> u?
<7> I might be part jewish. I have an ancestor from germany named Goldberg
<5> now you are chrisyian?
<7> yes. how did you know?
<5> i guess
<7> :)
<5> i m arabian muslem
<7> ok. from where?
<5> why?
<5> why do you ask?
<7> who knows
<9> SO, how bout them physics
<5> what do you mean?
<2> how bout them
<9> haha it's my firm believe that religion and science shouldnt be talked about in the same convorsation
<7> gimor, I mean who knows why we do as we do
<9> belief rather
<2> sometimes it's unavoidable
<9> this convorsation, however, was certainly avoidable
<5> who is the god in your religon?
<7> gimor, where are you from?
<5> seriosly
<9> lets talk about the velocity of dog sweat dropping from ear height of a german shepard, shall we?
<10> Brennan: lo
<10> l
<7> Brennan, compose yourself
<9> heh, all I'm saying is this convorsation cant end well
<9> and I have to listen to philosophy lectures all day
<9> I COME HERE TO BE A DUMB*** AND TALK ABOUT PHYSICS!
<7> Brennan, easily. ty to skip the dumb*** part
<7> try*
