Based on the Great Pyramid in Egypt which belonged to an advanced civilization due to construction techniques and the writings and drawings on the interior walls. Plus all the UFO activity in America (probably waiting to take over earth after we destroy it or something serious happening in 2012). And all the diasters we've been having, plus global warming, etc., etc. Maybe the UFO's are the advanced civilization and they come back to check on us because our time might be running out, possibly due to 2012. What do you think?

What is your opinion on natural or unnatural factors that determine the conscious presence we have in our individual bodies? What do you feel determines which pair of eyes you will look through? Is it possible that we are merely energy fields that migrate from host to host as we die?

Ok so I'm a senior in college trying to remember chemistry from long long ago. Specifically weak base titration. We have a solution of ammonia in water and we titrate it with 1.04 M HCl and have to figure out the number of moles of ammonia. So I use the amount of HCl used to find the moles of H+ present. The moles of H+ is equal to the moles of OH-. Then I used
Kb = [NH4+][OH-]/[NH3] to find out how much NH3 was in the water. It makes sense to me and seems to be right bt I don't remember for sure.

There are black holes at the center of galaxies with millions of solar masses and they don't explode, in fact just the opposite. Why would an even bigger mass explode?

Can some one plz help me figure out what i did wrong?

integral [ tan 2x dx ]
= integral [ (sin 2x)/(cos 2x) ] dx

*Now I rewrote the equation so that I have u'/u

= (1/2)* integral [ (2 sin 2x)/(cos 2x) ]

*Now that I have u'/u i can use the formula ... integral (u'/u)=ln u

= (1/2) ln (cos 2x) + C


My problem is that the answer should be - (1/2) ln (cos 2x) + C . In other words negative, but I have no clue how they did this.

Hello everyone. I know that recently there has been geomagnetic storm, and ironically my computer has been acting up this morning. I don't have a virus or anything; in fact it is working perfectly fine now. So, I've been just wondering if anyone else had experienced the same, or knows if whether it is possible.

With the development of the cotton gin is there a market for transgenic seedless cotton? Would this bring down production cost or is the cost of removing the seed worth having, since oil can be obtained from the seed.
