Oh Rayleigh?!

So the sky is blue because short wavelengths of light coming from the Sun (blue, etc.) are scattered more than long ones (yellow, red, etc.), reflecting the short wavelength light into our eyes instead of it passing through the atmosphere as part of white light. Sunsets are red for the opposite reason … but yeah, why isn’t it violet?

Violet has an even shorter wavelength than blue light. So does indigo, whatever that is. There’s a good logical case for a purple sky, right?

Want to know the answer? Why the sky isn’t violet?

Do ya? 

The truth is that the sky is both violet and blue. But the color receptors in our eyes don’t see violet very well, so we get the (incorrect) impression that the sky is just blue. Some birds actually see well into the violet and ultraviolet, so the sky must look trippy as hell to them.

forever

I don't believe in luck. I do believe we've known each other since forever, though. Her: Really? Yeah. You know how? When the big bang happened, all the atoms in the universe, they were all smashed together into one little dot that exploded outward. So my atoms and your atoms were certainly together then, and, who knows, probably smashed together several times in the last 13.7 billion years. So my atoms have known your atoms and they've always known your atoms. My atoms have always loved your atoms.

Stream the solar eclipse live from Australia

In under an hour the moon will pass between the sun and the earth and my attention will pass from cooking tea to watching the event live.

My mum always said things we lose have a way of coming back to us in the end, if not always in the way we expect.

Plato’s Theory of Forms or Theory of Ideas, holds that forms (the abstract quality or property of something) exist independent of Space and Time. It asserts that non-material abstract (but substantial) forms (or ideas), and not the material world of change known to us through sensation, possess the highest and most fundamental kind of Reality.

Forms are:

Transcendent - the forms are not located in Space and Time. For example, there is no particular place or time at which redness exists. Pure – the forms only exemplify one property. Material objects are impure; they combine a number of properties such as blackness, circularity, and hardness into one object. A form, such as circularity, only exemplifies one property. Archetypes - the forms are archetypes; that is, they are perfect examples of the property that they exemplify. The forms are the perfect models upon which all material objects are based. The form of redness, for example, is red, and all red objects are simply imperfect, impure copies of this perfect form of redness. Ultimately Real - the forms are the ultimately real entities, not material objects. All material objects are copies or images of some collection of forms; their Reality comes only from the forms. Causes - the forms are the causes of all things. They provide the explanation of why any thing is the way it is, and they are the source or origin of the being of all things. Systematically Interconnected - the forms comprise a system leading down from the form of the good moving from more general to more particular, from more objective to more subjective. This systematic structure is reflected in the structure of the dialectic process by which we come to knowledge of the forms.

comfort

there’s nothing wrong with choosing a comfortable life over a difficult one, as long as at each reevaluation and reflection you can truthfully say, “there’s nowhere better I could be than where I stand today”
