I think it just asks for how those ions are named commonly: see http://en.wikipedia.org/wiki/Ion "Common ions"

Thanks a lot for the question and the interesting answers. I oversaw the implications for memory handling. I apologize for my first answer, that was obviously totally wrong.

Could you explain, why this is so ? Is this a special of fortran ?

The performance should be the same for every case in every programming language.

How do you calc the intersection ?

You really think the speeds after the collision are greater ? You think those balls accelerate for the rest of their life on that table ? http://www.real-world-physics-problems.com/physics-of-billiards.html

As i pointed out before the correct speeds are: queue ball = 1.2 8-ball = 2.6 - 1.2 = 1.4

You might mean that: Science Daily 2009 "Women Have A More Powerful Immune System Than Men, Study Shows" http://www.sciencedaily.com/releases/2009/05/090511180740.htm

no idea where you get that velocity from The speed of the 2nd ball is 2.6-1.2 = 1.4 ! as the masses are equal, the sum of all speeds before the collision must be = the sum of all speeds after the collision. http://en.wikipedia.org/wiki/Collision#Billiards

The speed of the 8-ball cannot be greater than the speed of the queue ball. I have no idea about the math, but i would guess that the angels of the two balls to the original direction after collision, should be proportional to their speeds. A special case of hitting the 8-ball is that both...

What else than light, is a camera filming ? Actually a camera IS a detector for light. :wink:

Societies undergo a process of Evolution like biological species. "Freedom of people", "Human Rights" thou beneficial for the individuals, might have been no advantage in survival for the societies themselves until today.

Its interesting, why human females live almost twice as long, as they are able to give birth. Obviously the grandmothers are good for something. Probably their increased knowledge and higher experience helps the grand-children to survive.
