Pattern on my tea

I got this pattern once on my tea. Ever since I took the statistical mechanics course I pay more attention to all the fluids in my life. The cup of tea is particularly interesting.

I used to drink coffee. Most of the grown-ups around me were drinking coffee when I was young, so I tagged alone. I was drinking two cups during the morning. As long as I took those two cups I was a happy person. One time I did not had any coffee. It was horrible, my head wanted to implode.

Last winter I visited my girlfriend at Wellesley College. She did not had a coffee maker, so I just started drinking tea. I guess the transition was smooth, since I do not remember having that much of an ache. Tea is suppose to be healthy too.

I like making my tea on a clear, see-through cup. That way I can follow the trail of particles diffusing on the water. The growing arms of the spirals is awesome. I cannot help but think of the particles approaching each other and then separating when I use my spoon. The sugar dissolves, sometimes yes and sometimes no.

But the fun lies at the surface of the cup. Here there is an ongoing exchange of particles with the air. If you blow on it you can see the lines of particles separating from the surface. The streams of vapor pulling more and more molecules into liberation.

OK. I am done with the poetry. Just wanted to appreciate a bit the beauty of a cup of tea.
