do you think that the rapture story in the bible is about mass alien abduction of humans ?
someone told me that it happens on regular time intervals, and that the story came from the last time it happened, they also said that it will happen again in 2012.
I just can't seem to it out of my head, so I am curious what others think.

A bicycle has wheels of radius 0.29 m. Each wheel has a rotational inertia of 0.079 kgm2 about its axle. The total mass of the bicycle including the wheels and the rider is 78 kg. When coasting at constant speed, what fraction of the total kinetic energy of the bicycle (including rider) is the rotational kinetic energy of the wheels?

I'm not exactly sure for how long there have been microwaves sold with metallic surfaces -in- them (as in the same space where the food gets cooked), but I know they exist, and have often been curious as to the details of their success.

It seems to me that photons, as part of a field, can only exist where gravity exists, however small the gravity field. Notice we see light from stars, though they are so far away, and photons bend in their path when traveling around massive objects such as the sun; so photons and gravitons interact, and it seems the g fields are much finer.

But I don't think photons can travel away from the cosmos. It doesn't make sense.

So then what is the nature of space at the edge of expansion in the cosmos with respect to fields?

This happened about six months ago. The electricity went off in my apartment for a minute or two, then came back on. Before the electricity went off, my answering machine showed 0 messages. After the electricity went back on, my answering machine showed 2 messages????? The circuit breakers are in my apartment and all were in the on position. Today, the electricity went off for a few seconds, then came back on. What could account for the incident with the answering machine incident? How is this possible? Why wouldn't the answering machine show 0? And no one called and left messages during the time the electricity was off.

Hi Im writing a program but don't worry about the coding in you answer: lets say I drop a ball in a perfect vacuum how would you determine the following (in order of importance too):
The bounce back velocity (and how it looses energy as it travels against the force of gravity)

The energy lost to friction (theres some kinetic energy equation I was pretty sure. thank you!

Prove the following theorem is true: “If a segment joins the midpoints of two sides of a triangle, then the segment is parallel to the third side and is half its length.”

In a company there are 100 employees, 50 men and 50 women. Out of the 50 men, 18 are fluent in French and don't know Math, 17 have a Phd in Math but don't speak French and 7 are fluent in French and have a Phd in Math.

Out of the women, 21 are fluent in French but don't know Math, 13 have a Phd in Math but don't speak French and 10 are fluent in French and have a Phd in Math.

The CEO wants to form a comission of 20 people, according to the following rules:

There must be 10 men and 10 women.
At least 8 people must be fluent in French
At least 9 people must have a Phd in Math.

How many comissions can the CEO form?

Thank you
