Caffeinated entropy

Often I wonder why people stir the milk in their coffee or tea for more than ten times. Cling cling cling cling cling. How annoying.

That's overstirring. A good mixing can probably be achieved in less than ten stirs. That is, the distribution of milk particles in the coffee quickly becomes uniform over time and plateaus after just a few stirs.

Funny. A uniform distribution of milk particles is then the goal of coffee stirring. I couldn't help but imaging what happens to the milk particles when you cease stirring. Well, assuming the latte as ideal fluid and a closed system, do the milk particles perform Brownian movement? If so, then the distribution of milk particles over time becomes...random? Maximum entropy?

Hang on. There's a reason to keep stirring then. To keep the milk particles from becoming randomly distributed. To keep them uniformly spaced in the coffee, or tea. To ensure each sip are consistent in taste and texture.

Can't really blame the old man next table for clinging clinging and clinging now, can I?

他方

再多几步。
再多几步?
他方,才变成立足的港湾?

无妨。有你,就好。

秋千人生

人生和秋千,一样遵守一起一落、一取一舍的原理。


and this is all life is like I think
you give what you can
and you take what you need
and then you move on
to the next giving and taking
and some give more
and some take more
and doesn't it even out in the end?
or do we shuffle off this earth unbalanced
leaning one way or another
into nothingness
