Possibly one of the most intriguing and yet lesser-known holidays is definitely an event that's referred to as Find a Rainbow Day. Since you may have previously suspected, this celebration happens throughout the month of April every year (in the end, the first spring is renowned for its great amount of those superbly stunning phenomena). Obviously, locating a rainbow isn't as simple as it may sound and when you're lucky enough to get end up outdoors soon after a lue-sky at the begining of April, you might just have the ability to catch a fast glimpse as well as have a snapshot of one of these simple wonderful natural occasions.As the exact roots of the day remain rather obscure, you will find lots who enjoy cooking colourful meals about this day goodies for example jello and snacks being probably the most common products. So, it seems that you will find indeed occasions when a little of rain isn't always a poor factor!

Why don't trillions of rainbows form in the sky? They do. You just aren't where you can see them. When you look at a rainbow, the droplets within the rainbow refract (bend) light so that it hits your eyes. Droplets above the rainbow also project color, but it shoots over your head. Droplets below the rainbow project color, but than light hits the ground in front of you. If you climb higher, you will see the rainbow formed by the higher droplets. That's why the rainbow appears to move as you move.

Why are rainbows curved? Because the droplets are spheres, not straight bars like a typical prism. In a typical prism, light that hits the prism is bent off-axis, all in the same plane as the entering light. When light hits a water droplet, the droplet bends it off axis as well, but since it is spherical in shape, it bends the light into a circle around that axis. That light forms a cone as it travels away. Now, prisms work in both directions. So when you look at light coming from a spherical droplet, that light must have entered the droplet off axis, anywhere in a cone about that axis. So when you look at a rainbow, visualize all of the droplets in the sky routing light from the entering cones onto the axis than intersects with your eye. Then pick out the droplets whose entering cones intersect with the sun. Those droplets form an arc.

If you climb sufficiently high above the horizon (or go up in an airplane or balloon), you will see the rainbow form a full 360 degree circle. Sometimes you can also see the full rainbow when using a fine-mist nozzle to spray water.

One last thing. Unlike a bar prism that refracts and transmits light, water droplets refract and reflect light. So they refract twice: once on the way in and once on the way out. See the source.

Who is your rainbow on a rainy day?

YOU are my Rainbow each and every day !! :)

What is the history behind the gay community adopting the rainbow as their symbol?

THE RAINBOW FLAG

A brief history

of a common gay symbol

Use of the rainbow flag by the gay community began in 1978 when it first appeared in the San Francisco Gay and Lesbian Freedom Day Parade. Borrowing symbolism from the hippie movement and black civil rights groups, San Francisco artist Gilbert Baker designed the rainbow flag in response to a need for a symbol that could be used year after year.

Baker and 30 volunteers hand-stitched and hand-dyed two huge prototype flags for the parade. The flags had eight stripes, each colour representing a component of the community: hot pink for sex, red for life, orange for healing, yellow for sun, green for nature, turquoise for art, indigo for harmony, and violet for spirit.

The next year Baker approached San Francisco Paramount Flag Company to mass-produce rainbow flags for the 1979 parade. Due to production constraints - such as the fact that hot pink was not a commercially available colour (Darn!) - pink and turquoise were removed from the design, and royal blue replaced indigo.

This six-colour version spread from San Francisco to other cities, and soon became the widely-known symbol of gay pride and diversity it is today. It is officially recognized by the International Congress of Flag Makers. In 1994, a huge 30-foot-wide by one-mile-long rainbow flag was carried by 10,000 people in New York's Stonewall 25 Parade, commemorating the 25th anniversary of the Stonewall riots.

Why the Rainbow?

Well, why not? But for those with a more metaphysical bent here are a few cosmic reasons.

In every ancient culture, the rainbow has featured variously as a god/goddess in its own right, a symbol of the unity of the world or, in the case of the Judiac-Christian tradition, God's promise of safety to humanity. Here are just a few of the forms these references take:

Iris

Iris is the Greek goddess of the rainbow, a daughter of the Titans, and cousin of Zeus. She is a multiple image, in effect, being a messenger to Zeus and his wife Hera, to worthy and beloved mortals, and, like the Norse Valkyries, conveyor of the souls of the dead (women only in Iris' case) to the blessed Elysian Fields. As with Christianity, due to her love for humanity and care of the wounded, her appearance in the sky was always taken as a sign of hope.

Buddhism

Some Buddhists believe the seven colours of the rainbow relate to the seven planets and seven regions of the earth. They also say the rainbow is the highest state of samsara before the clear light of Nirvana or heaven.

Islam

In Arabia, the rainbow is a tapestry draped by the hands of the south wind. It is also called Allah's bow. In Islam, the rainbow is made up of four colours: red, yellow, green and blue, related to the four elements.

Hinduism

In myths of India the Goddess Indra also carries a rainbow, known as Indra's bow or weapon. A part of the Indian creation myth says the Gods created an ocean of milk from which all living forms emerged. Airavata, a sacred milk white elephant, whose name means 'rainbow', was one of the first creatures born from the milk.

Judiasm

A promise of peace from God. After Noah's ark finally arrived on dry ground after 40 days and nights of rain later, God sent a rainbow as his promise that this great flood would never happen again.

Christianity

Apart from being the symbol of the reconciliation between God and humanity carried over from the Judiac tradition, the rainbow also retains references of the ancient Greek belief. With echoes of the Iris myth, some Christians of the Roman Catholic faith view it as the Virgin Mary bringing heaven and earth into harmony.
