Fort Night and Day

As the ever reliable and perceptive Miss Sam informs me, punkin, there is indeed only fourteen days left until your due date. This period of time is absolutely within the period of time that I can easily understand, and is therefore abjectly terrifying.

Are we really doing this? Am I really going to be a dad and have to know stuff, like why the sky is blue ( When light beams interact with particles suspended in air, the energy can be scattered or absorbed. Energy that is scattered causes a change in direction of the light path. The amount of light that is being scattered is a function of the size of the particle relative to the wavelength of the light falling on the particle. Particles that are tiny compared to the wavelength of the light scatter selectively according to wavelength. While all colors are scattered by air molecules, violet and blue are scattered most. The sky looks blue, not violet, because our eyes are more sensitive to blue light (the sun also emits more energy as blue light than as violet)) and what makes cars go? (internal combustion, talk to your grandpa Phil)

I need to learn how to juggle in the next two weeks.

Love you.

And that's before you even get the question that I always asked (& would still like the answer to if anyone has it). Why is the sky blue?

I know it looks like the same question, but what I actually need to know is why is that thing above us called 'sky' & why is that colour called 'blue'. While I'm at it, who decided that colours are called 'colours' & why? Why? Why?

Ah, the joys of parenthood.
