Imagine if you discovered a free energy source, or designed teleportation technology, or a time-machine etc.

There must be people out there who have discovered/designed things but kept their ideas to themselves for fear of being exploited or hushed by the government...

What would you do?

Please could somebody walk me through this example as I'm totally confused and talking to the book just doesn't help!?

Question

Use the method of CTS to write 2x^2 - 5x + 11 in the form a(x+b)^2 +c, where a, b and c are rational numbers.

Solution

First take out 2 as a factor.

2x^2 - 5x + 11 = 2[x^2 - 5/2x + 11/2]

Now complete the square on the contents of the square bracket,

= 2[(x - 5/4)^2 - 25/16 + 11/2]

= 2[(x - 5/4)^2 + 63/16]

= 2(x - 5/4)^2 + 63/8.

Any help greatly appreciated! :o)

After 9/11 US attacked afghanistan, then attacked iraq, really stupid.......9/11 carried out by Bin Laden has his base in pakistan, why the hell does he not attack pakistan. No wonder we saw more attacks in spain and uk.

Pakistan and saudi are the real threats, Bush wake up shoot the real terrorists.

( THEORY 29 866 6548374 )

to grasp this you need to understand the universe and this idea

no matter = no distance

the next part of understanding this is the idea that e=mc2 can be reversed from
energy = mass X light X 2 into...
mass ( at C2 ) = energy
but why C2? why not just C Because... ( do, read on... ) We are already expanding at the speed of light


so when mass reaches C2 it breakes up and creats a explosion of unimaginable proportions ( eg. big bang )

the idea is that in the original universe E = MC because we were effectivly sitting still ( well atleast not expanding at the speed of light )
( refer to no matter = no distance )

so the idea is that after the original big bang matter is expelled at the speed of light ( us, now )
therefore for another big bang mass would need to reach 2X the speed of light to release the energy

How do scientists measure how far a star or a galaxy is? and is that fool proof?

For e.g if a big star is far off and a smaller star is near by and they might look similar in intensity and size to naked eyes, but do scientists really have methods to figure out their reals distances.....assume that both of those stars are moving away from us at the same velocities...

I'll let you choose:
a) Check to death a few numbers starting from 10 to the power of 30 to see if any are perfect.*
b) Write down numbers at random and find there nth terms.
c). Follow the lines round and round and round a parralellogram forever. Then realise it's not going to change anything so give up.
d) Count to more than 1,000,000.
e) Calculate sums to 50 decimal places without a calculator.

*If you think I don't know Euler's Formula I do and I believe that the formula may be wrong. There might be anumber missing.
