The switch I am looking for is special in that it does not allow you to throw any other poles on the switch untill you open the first poll.
It works similar to this:

(press button 1)-(cant press any other button)-(press button 1 again)-(can press anyother button)...

I really would like one where a water drop hits a standing body of water.
The reason is I need to run the video thru a set of mathematical software formulas for testing purposes.

What would the size of the earth be ( in cubic centimeters) if:

1. It was "squeezed" into a density of a white dwarf?

2. It was "squeezed" into a density of a neutron star?

3. It was "squeezed" into a density of a black hole?

if males are made from an X chromosome and a Y chromosome, and females are made from two X chromosomes, with modern genetic technology couldn't we take an X chromosome from each partner in a lesbian couple (or an X and a Y from a gay couple) and produce a viable female (male) fetus?

Is high frequency EM radiation responsbile for what we sense as "solid matter"?
I was just thinking about this lately..There is a whole range of EM radiation. As the frequencies go up, so does the energy levels.

Radio, then light, then UV, then X-rays, then Gamma rays, then cosmic rays, and beyond?? Each with a smaller wavelength, and higher energy level, capable of penetrating right through more and more matter. Eventually, this energy could probably go right through a large celestial body (cosmic rays?)

If these high frequency rays form standing waves, then maybe this is what we refer to as matter, and why we can convert matter to energy and vice versa.

If we speculate that gravity is caused by these rays, maybe the idea of a gravity sheild is possible...maybe this is what is happening at the core of the earth? And why its so hot? Cosmic rays being concentrated there?
These are speculations, but its an interesting line of thought.
Any creative answers/thoughts?

I mean, hundreds/thousands of years ago, how did countries across the world decide on a uniform date and year? They must have had their own beliefs of what year they were living in. How did they progress to the point where we are now?

Thanks for any help!

I have a 3 pin Bi-LED, two anodes and one cathode. I am using it with
two transistors, each transistor controls a anode. The only way I can
sucesfully use this Bi-LED is if I attach 2 signal diodes to the
cathode (gnd), thus creating two seperate cathodes, connecting them to
the collector of the transistor.

How will this effect the formula in choosing a resistor on the Bi-LED's anodes? I would assume that a smaller resistance would be chosen.
It should be noted that one of the transistors are also powering a 150mA relay.

We are told life started with an amoeba [one cell] and was a matter of evolution from apes to modern man. However, my question is where did the Amoeba come from in the first place, who made an Amoeba then???
