I heard that it's already been done and we humans are a race of biters that are trying to copy the mechanics of alien spacecrafts that have infinite fuel engines that run on black matter. Is this true?

I have just found that there are about 50+ tadpoles in my backyard pond. The pond was created by using a plastic liner and has a pump that circulates water through an old-time water pump (the pond is about 5 feet by 3 feet). I have read that you should change the water frequently so that it doesn't get murky and discolored; however, I don't want to remove all of the tadpoles and add fresh water if I don't have to. Will they survive if I don't change the water? Could I just add tap water when the water level falls a bit, or do I need to change ALL of the water? How many tadpoles will survive to become frogs? Any other personal or other information you have about tadpoles and keeping them alive would be greatly appreciated!

Is the H-bomb or the atom bomb? I'm not sure...I asked all those other questions because I don't understand how Einsteins theory, which seems so enlightened and innocent, is also related to war.

I'm enjoying this book so far but I'm unsure of what parts are fact and what is fiction.

What is an equation or the answer to this problem:

I have to come up with the solution of four random digits. What are ALL my possibilities from 0 -9 for four random digits, or what’s the equation so that I can attempt to solve it on my own or get my calculator or computer to do it for me?

Example: _ _ _ _ or ? ? ? ?

Example:
0000
2345
9999
…
And so on…

At least tell me how many possibilitys 4 digits can have with 0-9 being the digits.
That will help A LOT too.



THANK YOU!

I need to press some material in a bonding process and need to exert 200 p.s.i. on this material. Assuming that by using a tool I can press directly onto an area 1 square inch, can I exert 200 p.s.i. on this area?

I need to know the name of the number I.E. million billion trillion Ect.
I am trying to find out how many possible credit card combinations there are. The highest experation date as far as the month/year goes is 12/10, so if we start from 07/06 we end up with 41 possible categories, so if we take our number that comes after 999trillion and times that by 41 we end up with all possible combinations for the next 3 years 5 months. Minus unusable numbers like 0000 0000 0000 0001. On any given credit card you may have 4 zeros in a row so in reality all combinations possible would have to be nine hundred ninety nine billion times 41.
Example: 5667 9877 0000 1234 Exp. 09/05
Any thoughts?

Using all numbers 1 - 9 construct the tic tac toe board so that the rows, columns, and diagonals each have a different sum.

123
456
789

The above does not work because there are multiple lines that add up to the same number 15.

Good luck !

Can you do it by subtracting x from the left side only and subtracting 0.999 from the right side only.

The question really is, can you do an operation on one side of the equation without doing the same thing to the other side.

I have heard that bones do not burn or take absolutely ages to burn...so when someone is cremated, what happens to the bones?

I had an argument with a girl who claimed that women can be just as strong as men. I disagreed and said the strongest man is still stronger than the strongest woman. Even during puberty, boys grow bigger muscle mass than girls do. What do you guys think?

Two cars start off at the same point on a straight highway facing opposite directions. Each car drives for 6 miles, takes a left turn, and drives for 8 miles. How far apart are the two cars?

A promotional deal for long distance phone service charges a $15 basic fee plus $0.05 per minute for all calls. If Joe's phone bill was $47 under his promotional deal, how many minutes of phone calls did he make? round to the nearest integer if necessary.

Hi, I am curious what people think makes a good science teacher. What do you want out of a science class? I'm have taught before and will be teaching again. I'd like to have some input from a broader sample.
