 Science of the Rainbow

The spectrum depends upon light of different colours being slowed by different amounts: the refractive index of a given substance, say glass or water, is greater for blue light than for red. You could think of blue light as being a slower swimmer than red, getting tangled up in the undergrowth of atoms in glass or water because of its short wavelength. Light of all colours gets less tangled up among the sparser atoms of air, but blue still travels more slowly than red. In a vacuum, where ther...

 Unweaving the Rainbow Makes it More Beautiful

Newton's unweaving of the rainbow led on to spectroscopy, which has proved the key to much of what we know today about the cosmos. And the heart of any poet worthy of the title Romantic could not fail to leap up if he beheld the universe of Einstein, Hubble and Hawking. We read its nature through Fraunhofer lines - 'Barcodes in the Stars' - and their shifts along the spectrum. The image of barcodes carries us on to the very different, but equally intriguing, realms of sound ('Barcodes on the ...

 Making Forced Connections

The basic process for making forced connections, as outlined by Koberg and Bagnall, is simple and sound. List possible features of the object you are trying to creatcte, one le feature per column. For example, the features might include cololor, size, anc shape. 2. In the column under each feature variable, list as many values for that variable as you can. For example, under color you might list all the colors of the rainbow, as well as black, white, gold, and silver. 3. Finally, random...

A technique for coming up with new ideas. This could be done with the mxplx rand() function, using it to find random memes and then forcing onseself to find connections between the ideas.

 Reality Teaches Us

At birth one may stand at the cross-roads for only a few lal. The adjustments are peremptory. The human mechanism must adjust itself to the new world. If it does,—then life. Sometimes it is necessary to "slap" it. That is "science" giving a first lesson in adjustment. An adequate supply of oxygen for the cells of the body is the first problem man faces when he comes into this world. Every pink pill is not a piece of candy. Science goes to the rescue and re-establishes adjustments. Man tires...

We start out trying to figure out the world, and science teaches us the lessons, but when we overbelieve--go beyond empirical evidence--we "may spoil the garden."

 Newton's Experiment Proving White Contains All Colors

Newton wasn't the first person to make a rainbow with a prism. Other people had already got the same result. But many of them thought the prism somehow 'coloured' the white light, like adding a dye. Newton's idea was quite different. He thought that white light was a mixture of all the colours, and the prism was just separating them from each other. He was right, and he proved it with a pair of neat experiments. First, he took his prism, as before, and stuck a narrow slit in the way of the co...

Using a prism to split light into a rainbow, he then used a lens to merge the rainbow back into white light and split it apart again.

 How a Rainbow Works

If you want to see a rainbow you ' have to have the sun behind you when you look at a rainstorm. Each raindrop is more like a little ball than a prism, and light behaves differently when it Sits a ball from how it behaves when it hits a prism. The difference is that the far side of I raindrop acts as a tiny mirror. And that is /hy you need the sun behind you if you want 0 see a rainbow. The light from the sun turns somersault inside every raindrop and is reflected backwards and downwards, wh...

A fantastic explanation of how sunlight reflects off of raindrops to form a rainbow, which would be a rain-circle if the ground didn't get in the way.

 Rainbow More Beautiful Through Science

Nor ever yet The melting rainbow's vernal-tinctur'd hues To me have shone so pleasing, as when first the hand of science pointed out the path In which the sun-beams gleaming from the west Fall on the watery cloud.

Poet describes how his appreciation of the rainbow's hues are increased by knowing through science that they are created by sunbeams on watery clouds.

 It is Ridiculous to Embelish Already Fantastic Things

Therefore, to be possess'd with double pomp, To guard a title that was rich before, To gild refined gold, to paint the lily, To throw a perfume on the violet, To smooth the ice, or add another hue Unto the rainbow, or with taper-light To seek the beauteous eye of heaven to garnish, Is wasteful and ridiculous excess.
