Sunny London

I look at the sky while I was walking to uni, the sky is clear and blue ---- morning was bright and with full of hope, although is freezing.

When you see no cloud, which means it's a freezing day, coz the cloud prevents the heat losing from the earth ; when you see clouds, the heat retain on the earth, but the sun cant shine through, and gives a dull day.

Light has amazing properties, in science we call "wave-particle" dual properties. Wave has a wavelength, particle has a mass.

So when light shines through the cloud, does the particle of light mix with the cloud particle, and does the light particle mix with the particle in the dust? If so can we characterise it?

People used to think that the motion of dust is a Brownian motion, meaning it's a random motion. But recently physicist manage to characterise the uncertainty motion of dust, they actually developed a model to show the random motion. (Well, you have to believe that people actually sit in the lab and "observe" the dust, and they get paid, i mean well paid !! : p)

So is there really a "random" or "uncertainty" principle? Random is no longer random, uncertainty is "certainly" recognised as uncertain.

The deeper you go, the closer you realise there's a CREATOR.
