Like me on this computer now, writing this question which will probably never be answered.
And if so, will we ever intervene with ourselves?

Have there ever been any stories of an astronaut getting disconnected and floating off to die in space while performing a spacewalk or other routine maintenance? This thought sprang to mind while reading a recent article of the astronaut who heaved two pieces of debris into space.

I've read everywhere that the best times are the 12th and 13th, but I'd like to book a stay at a campsite on the 11th (which is a more convenient Saturday) to watch instead. Assuming the same weather conditions as Sunday, will there be anything to see? How much? When on Saturday night will be the best to watch?

Around the outside of My house Sparrows break our light fixtures and make nests in them and every time we go to clean it out and install a new fixture we hear new babies! They are like there 5 set of babies and I was wondering how many times they are going to reproduce so we can get them out of there and use our lights again.

The time it takes to cover the distance between two cities by car is inversely proportional to the speed of the car. The trip takes 3 hours for a car moving at 68 mph. What is the speed of a car that makes the trip in 12 hours?

I can`t find a larvae identification guide online anywhere. This thing was cool. Looked like a large typical maggot looking larvae with an inch and a half long thin tail. Total length was about 2 inches. There were three of them found in the bucket. Really neat looking and any help on identification would be appreciated...

Factor the polynomial completely. If the polynomial cannot be factored, write prime.
x^3 - 343

(x + 7)(x^2 - 7x + 49)
(x + 343)(x + 1)(x - 1)
(x - 7)(x^2 + 49)
(x - 7)(x^2 + 7x + 49)

Is it possible to measure gravitational acceleration 'g' near the earth's surface using a centrifuge? Someone told me that if you put a small object like a pebble in a centrifuge, start the centrifuge off at a high speed, and slowly lower the angular speed. At the speed the pebble falls out, the gravitational acceleration will equal omega squared times r (radius); is this valid? (omega is angular speed, the derivate of the angle with respect to time, or 2pi radians/period if angular speed is constant)

I do not think so, because the force here is the frictional force between pebble and centrifuge, and not the gravitational force.

Also, If you swing anything in a vertical, circular pattern, anything inside of it will experience two forces at the top of the arc. If the measurable, centrifugal force is less than the force of gravity, the object will fall. Is this correct? If so, can this be used to measure 'g'?

If not, is there a way to measure 'g' using a centrifuge? Thank-you.

Just say for no reason that you were able to dig a hole through the earth, when you get to the center of the earth would you have to start digging upwards? Remember where ever you are people are standing up.
