There is two circuits, and if one is active (flowing current) then it opens a switch in another. Some would say that is a relay, but the problem is, the circuit which activates that switch, only has a pulse. What I mean is the circuit is only complete for a short time, and needs to toggle the switch on and off everytime there is a pulse of current which flows through the circuit. The situation is a modern computer power button, which closes the switch when it is pushed, but when released, it breaks the circuit again. How can I make that circuit toggle the switch on the second circuit everytime current puslses through. For example, a pulse passes through, the switch is toggled on. Then another pulse is passed, the switch is toggled off. Then another toggles on etc.

In the past, scientists believed that the universe was infinite with an infinite set of stars, and therefore there would be no central point that would cause the stars to fall into each other, but in the course of time they realized we have to consider that the universe is finite with a finite set of stars. If that is true, how come there is no point in the universe where the gravital forces of a set of stars outweight those around them and cause all other stars to collapse with each other?

But HOW do i know that CuSO4 becomes:
Cu 2+(aq) + SO4 2-(aq)???
