I have. Sometimes they're lucid dreams in which I know i'm dreaming. Other times I don't even know i'm still sleeping and i have an out of body experience or i astral project somewhere.

Sometimes i have dreams of levitating but in them i prevent myself from continuing to the point where i'm flying because I don't know it's a dream and i get scared.

Additional Details

The graph of G(x)=1/f(x), where f(x) is a quadratic function, is shown. The y-intercept of G(x) is 1/9 and the maximum point of G(x) is at (2,1).

The graph sorta looks like ahill which does NOT cross the x-axis.

Determine the equation of f(x) in general form.

Could you please explain show steps in solving the questions or at least explain how you came up with the answer.

Imagine a huge pair of scissors, with blades one light year long. The handle is only about two feet long, creating a huge lever arm, initially open by a few degrees. Then you suddenly close the scissors. This action takes about a tenth of a second. Doesn't the contact point where the two blades touch move toward the blades' tips much faster than the speed of light? After all, the scissors close in a tenth of a second, but the blades are a light year long. That seems to mean that the contact point has moved down the blades at the remarkable speed of 10 light years per second. This is more than 108 times the speed of light! But this seems to violate the most important rule of special relativity -- that no signal can travel faster than light. What's going on here?

The Mayan's were a very advanced culture. They predicted eclipises through star formations and predicted the weather through highly advanced mathimatical reasoning. There calender is more accurate than the one we use today by 10/1000th. Their calender ends on 2012. Tell me what you think..

Wouldn't the most mass equal the most gravitational pull? Are there concentrations of dark matter or is it spread evenly out over the universe? Since the universe bends, is there a center to the universe? Having one of those curoius days and need some help feeding the beast. Thanks in advance

This item was in today's Space.com news.
http://news.yahoo.com/s/space/20070103/sc_space/scientistsspotblackholeinunlikelyplace
In part, it says:
"Astronomers have spied a small black hole nestled in the middle of a packed star cluster...
The discovery...is surprising because some theories predict that gravitational interactions among black holes inside a cluster would simply kick most or all of the black holes out of the cluster.
Scientists think [that] because black holes are usually among the most massive objects in a globular cluster, they sink to the cluster's center. There, they typically pair up with either a star or with another black hole that has also [sunk] into the cluster's middle. A binary system made up of a black hole and a star can be stable, but when two black holes pair up, strong gravity interactions between them are thought to give one or both the boot."
MQI, why wouldn't all the black holes inside a star cluster, or anywhere else, simply merge???
Thanks.

16th of July 1968, Amstrong the first one to land on the Moon...right?? It has been much debated if this was really true or was just a fake experiment...but we never found out the real truth.

And why hadn't they sent other astronauts on the moon in all theese 40 years, but only in space..?

I want to know your oppinion.. was this true or was it a fake experiment just to mislead Humanity??

Is this an X-file of mankind?

This is the problem I am having trouble with, if you could show me step by step how to do this I would be so thankful.

When 500.0 g of octane, C8H18, is completely burned, what volume of CO2(g) is produced at standard atmospheric pressure and a temperature of 18 degrees C?

The unbalanced equation for the reaction is:

C8H18(l) + O2(g) ---- CO2(g) + H2O(g)

Use truth tables to establish the following logical equivalencies known as the distributive laws.


1.P v (Q ^ R) ≡ (P v Q) ^ (P v R)
2.P ^ (Q v R) ≡ (P^Q) v (P^R)
