whats a ubercrystal????? a crystal with a fractional dimensions like fractals?

sorry found out why

[math]

$$

\eqalign{

& r = \frac{{\sum\limits_{i = 1}^n {x_i y_i } - \frac{{\sum\limits_{i = 1}^n {x_i } \sum\limits_{i = 1}^n {y_i } }}

{n}}}

{{\sqrt {\left( {\sum\limits_{i = 1}^n {x_i^2 } - \frac{{\left( {\sum\limits_{i = 1}^n {x_i } } \right)}}

{n}^2 } \right)\left( {\sum\limits_{i = 1}^n {y_i^2 - \frac{{\left( {\sum\limits_{i = 1}^n {y_i } } \right)}}

{n}^2 } } \right)} }} \cr

& \chi ^2 = \sum {\frac{{\left( {O_i - E_i } \right)^2 }}

{{E_i }}} \cr

& r_s = 1 - \frac{{6\sum {d^2 } }}

{{n\left( {n^2 - 1} \right)}} \cr

& f(x,y) = \int_x^y {\tfrac{1}

{{k^2 }}} dk = \left. { - \frac{1}

{k}} \right|_{k = x}^{k = y} = \frac{1}

{x} - \frac{1}

{y} = \frac{{y - x}}

{{xy}} \cr

& D(f) = \{ x,y \in R:x,y \ne 0\} \cr}

$$

[/math]

what am i doing wrong. doesnt work!!

y isnt it working?

[math]

\frac{{ - b \pm \sqrt {b^2 - 4ac} }}

{{2a}}

[/math]

<math>\sqrt{x^2+7}</math>

$$

\eqalign{

& r = {{\sum\limits_{i = 1}^n {x_i y_i } - {{\sum\limits_{i = 1}^n {x_i } \sum\limits_{i = 1}^n {y_i } } \over n}} \over {\sqrt {\left( {\sum\limits_{i = 1}^n {x_i^2 } - {{\left( {\sum\limits_{i = 1}^n {x_i } } \right)} \over n}^2 } \right)\left( {\sum\limits_{i = 1}^n {y_i^2 - {{\left( {\sum\limits_{i = 1}^n {y_i } } \right)} \over n}^2 } } \right)} }} \cr

& \chi ^2 = \sum {{{\left( {O_i - E_i } \right)^2 } \over {E_i }}} \cr

& r_s = 1 - {{6\sum {d^2 } } \over {n\left( {n^2 - 1} \right)}} \cr

& f(x,y) = \int_x^y {{\textstyle{1 \over {k^2 }}}} dk = \left. { - {1 \over k}} \right|_{k = x}^{k = y} = {1 \over x} - {1 \over y} = {{y - x} \over {xy}} \cr

& D(f) = \{ x,y \in R:x,y \ne 0\} \cr}

just testing my new found TeX skills

cool. i got mathtype. havent explorered it properly. i didnt know it can convert o tex. going to have a look now.

by the way. which uni do u go to?

When information is stored on disks, minuscule regions that make up each bit of data are magnetized in one direction or its opposite, to represent a 0 or a 1. Rewriting data involves sending an electromagnetic pulse that reverses the spin of selected bits. Accelerate the pulse and you shorten the time needed to store or rewrite information.

But if the pulses come too quickly and intensely, the high energy involved makes some of the magnetic changes happen randomly instead of predictably and reliably, according to a group of researchers writing in Wednesday's edition of the journal Nature.

So what do u think will replace the current storage technology? Any Ideas ?

I quite used to like QED at the end. but i am starting to take to the Empty of Filled in square. which most of my lecturers use.

also quite impressed with the notation ur created by Tex. I cant be bothered to lean it

nice one.

if i was asked to "show" that lim n -> inf of (1+x/n)^n = e^x

i would have taken f(n) = (1+x/n)^n

and g(n)=ln [f(n)]

found the limit of g(n) by using L'Hopitals Rule . =x

then limit of f(n) is an exponential of something which is tending to x

therefore lim of f(n)=e^x

I am not sure this constitutes a formal proof.

you probably have to prove L'hopitals rule and other stuff as well.

dont blame each other . Blame me!!!

anyway thnks for the answers. gonna toss a coin 100000000 times and see if i can get a result.(i dont think ill live long enough to do that)

When u flip a coin . there are three possible events

E1= Head

E2=Tails

E3=landing on its side

now P(E3) must be really small. but even if its small, imagine the number of times coins have been flipped!!!. there must have been a coin landing on its side.

Just wanna know if there is any record of that ever happening.

it can be shown that

(1+x/n)^n < e^x< (1+x/n)^(n+1)

what about the one where u have to sex pee, and you go in your dream, but you DO feel releived!

I find it fun using the stuff i leanred to show stuff i know actually works. like if i just learned integration using polar co ordinates. i check if the area of circle is really pirsqaured. or to check a length of a curve etc etc. good practice and so much fun

quite like "the lost world" by Sir. A.C Doyle. there was another book written by the same guy which did Andromeda Strain. which i liked really. cant remember the name. The i went looking for andromeda strain in the library. couldnt find it. I read so much sci fi and fantasy i cant remember any of them names

go for MathType its really cool. u can get the 30 day demo which also acts as the full program but needs the key. u can find the key anywhere.

i saw that in one episode of simpson as well.

. But that trains your speed and reaction, doing push-ups on the tips of your fingers or with closed fists trains your finger and wrist strenght.

have u seen bruce lee do a one hand push up with two fingers? absolutely mad. saw a clip from some documentary

nope , the really tough one is u push up from the floor and clap ur hands behind ur back and have to get them to the front again for the landing. and keep doing that 40 times at a go!! i saw that in a fitness mag. it was under "Harcore Exercises"

i can manage to touch my hips. but no way i can clap my hands behind my back. it require to push urself up upto 45 degress. there was a sequece of pics in the mag where some guy was doing it.

i used to do with close fists but cant be bothered nowadays

actually most of the stuff we think about has been thought thousands of times by many prominent philoshophers and theologists. i just cant be bothered to figure stuff out anymore. Just when i figure something out in maths. i find out that we will be doing that in the next lecture. or i look in a book and its already there.

i have had a weird dream once. i was lying on a bed. then the phone started ringing. i waited for a while. the phone kept ringing then i got up and went to pick up the phone. i picked up the phone and said hello, and the phone still kept on ringing. then i found myself on my bed, half awake , half asleep , with the phone still ringing !! . then i got up and answered it . and finally it stopped ringing

yeah i started at age less than 15, learning new ways as well rite now.

pi is irrational . i.e it cannot be written as a fraction p/q where p belongs to Z and q belongs to N. 22/7 is only an aprroximation. and quite a bad one as well.

about the question. cant really help you. cos i cant understand what ur trying to say.

i know it sounds bad learning to crack ur neck. but imagine u get into a fight. and just before u start fighting u look the other guy in the eye and crack ur neck twice by twisting ur head each way. that would look pretty cool, also u would look like a hard nut. lol i am always impressed when my fren does it. a good party trick

no. thats not the one. but someone in this forum has the same one as me. even the file name is the same "start.exe"
