Then car oil will be the best to lubricate the ramp grease will be second best, Vaseline is going to be third best, then liquid soap is going to be forth best, and vinegar is going to be in last place

Has anyone ever tried it? If I had two cell phones, I would do it myself, but I don't. I guess you call one cell with the other cell, prop the phones up, place the egg inbetween them, and then wait one hour. Supposedly, the egg cooks almost completely after this time has passes. Any input on this?

Some creationists have told me that common structures in almost all animals, such as eyes, lungs, heart(s), kidneys, etc., are proof of a common creator. As an evolutionist, how do I respond to this?

Tickets to a concert that were purchased in advance cost $4.50 each, and tickets purchased at the box office on the day of the concert cost $8.00 each. The total amount of money collected in ticket sales was the same as if each ticket purchased had cost $6.00. If 180 tickets were purchased in advance what was the total number of tickets purchased for the concert?

I am trying to understand a certain ASTM standard for Fire Tests of Building Construction and Materials. The points that determine the Time-Temperature Curve for this standard are as follows:

1000F at 5 min.
1300F at 10 min.
1550F at 30 min.
1700F at 1 hr.
1850F at 2 hr.
2000F at 4 hr.
2300F at 8 hr. or over

I guess I'm just stupid... but what does this mean?! I know the definition of a time-temp curve is the thermal analysis curve produced by the plot of time vs. temperature, but does this particular curve mean that, as something (whatever kind of construction material being tested) is exposed to heat, it should reach a temperature of 1000F after 5 min, 1300F after 10 min, 1550F, after 30 min, and so on? Please help me understand this!!! Any helpful information about it would be greatly appriciated.

Oh, and Happy Thanksgiving! :-)

What is the formula for getting the number in the nth row and mth column of Pascal's Triangle (i.e. the one used in Binomial Expansion), and why does it work? (I am more interested in the why part; I can look up the formula easily. I want to understand why it works).

Thanks,
Jack
