FALL FASHIONS:

Butterfly wings work like LEDs (BBC, 11/18/05)

When scientists developed an efficient device for emitting light, they hadn't realised butterflies have been using the same method for 30 million years.

Fluorescent patches on the wings of African swallowtail butterflies work in a very similar way to high emission light emitting diodes (LEDs).

These high emission LEDs are an efficient variation on the diodes used in electronic equipment and displays.


Hardly surprising that it would take us millions of years to ape His Design. Of course, given the speculation that the whole Universe is just a big holograph, the whole thing is just Light.

It was mind-boggling to me when I realized that, in theory, a lit match could produce enough light to be visible to billions of people. But of course I was far from the first person to notice that:

For example, Astronomers inform us that the Star draconis is distant from the Earth 38. 000, 000. 000. 000. miles. The Light that proceeds from that Star, therefore, must fill a Sphere of 78. 000, 000, 000, 000, miles in diameter, and every part of that Sphere equal to the size of the pupil of the human Eye. Light is Matter, and every ray, every pencil of that light is made up of particles very little indeed, if not infinitely little, or infinitely less than infinitely little. If this Matter is not fine enough and subtle enough to perceive, to feel and to think, it is too subtle for any human intellect or imagination to conceive, for I defy any human mind to form any idea of anything so small.

oj,

I think you mean hologram, unless you're telling us that the Almighty wrote the universe. A holograph is a document in the hand of the author.

Either works, but you're right.
