They will say its societal pressure. Yet, they cannot explain further. This is a term invented by feminists to excuse lack of women in science. Even if there is a pressure it is to drive women INTO scientific areas. "Continuing my previous post #28: Sam_, your are trying to be too...

Don't tell me I'm too young. So what? I've seen enough to make a conclusion and that's that. BTW, I am in college. As I said a female who has some degree in some scientific subject is NOT necessarily an intelligent female IMO. But someone who passionately likes to solve logical problems and...

Hi, I'm a 17 year old male who has some questions about the women today. I have a passion for maths, programming, engineering and science. Being a heterosexual male in search of a suitable partner, I'm finding it very hard to find a girl who likes the same things as me. In fact I have seen none...

So help me with this: this are simultanious equations. 1/(x^2) + x^2 -7 = 0 && 1/x + x -y = 0 What is y?

Homework Statement 0.1 dm^3 of a gaseous hydrocarbon may require 0.45 dm^3 of oxygen for a complete combustion to give 300 cm^3 of Carbon dioxide. All volumes are measured in the same environment. Calculate the molecular formula of the hydrocarbon. The Attempt at a Solution i tried...

Show that there are infinitely many pairs of positive integers (m, n) such that (m + 1) / n + (n + 1) / m is a positive integer.

For n a nonnegative integer, what (in terms of n) is the sum of the n-th powers of the roots of the polynomial x^6 - 1 ?

using System; public class Addition { public static void Main( string[] args ) { int number1; int number2; int sum; Console.Write( "first integer: " ); number1 = Convert.ToInt32( Console.ReadLine() )...

So? any takers? Come on!

This is for very beginners, trying to start up with C#. I'll post some short notes when I'm free. I hope to make this into a useful collection of information on C# programming language. Feel free to ask any questions. For now, you will need Visual Studio .NET, there is an express edition...

I think you have the right idea, but there are some details. There are N+1 ways to have a+b=N, but they do not all have equal probability. To have a=b=N/2 is much more probable than to have a=0 and b=N. The probability of a=M and b=N-M is {(N)!/[(M)!(N-M)!]}/(0.5^N), so to find the mean you need...

That is an ellipsoid. http://en.wikipedia.org/wiki/Ellipsoid The surface area is a bit complex if you want exactly. http://en.wikipedia.org/wiki/Ellipsoid#Surface_area

That is correct. can you please explain how you got that?

In a gambling game, a gambler wins 0.5 for each 1.0 of the bet if a coin toss is "heads," and loses 0.4 if the coin toss is "tails." So if he bets five Australian dollars, then he wins 2.5 if the coin is heads, and loses 2.0 if it is tails. Now, suppose someone plays this game repeatedly with...

Hi, can you please explain to me how Ramanujam got this formula for pi. Thank you.
