In 2020, I spent some time to work on the front and the back cover of my thesis. With huge help from a designer, I was finally able to realize what I had in mind for my thesis.
Feels good.
How a vortex is created by a beating cilium and propagates away from the cell.

In 2008, I was fantasizing some floating tower full of small electromagnets (coils) that could attract Fe3+ and Mn2+ in sea water - so as to attract algae and avoid harmful algal bloom in coastal area. Yes, it looks crappy (because the whole thing was drawn in MSpaint by mouse-clicking). Huh... a lot of work.
As I said, I am an experimentalist, and that means a propensity of recording and analyzing - every where. In 2019, when my daughter is 3 months old, I started to record her sleep-awake pattern. It appeared that in the first month, her sleep duration distribution follows a periodic pattern (left), while her ability to stay awake is almost Gaussian (right). See the color coding in the upper schematic drawing. These sleeps only include day-time ones.
As a follow up study (when putting her to sleep, I need to think about something to hang in there), I found that her stamina to stay awake transitioned from 110 min to ~140 min. And after 2 months, the previous 110 peak seemed to have doubled.
What happened next? I realized that I couldn't let her sleep as much as she wanted, otherwise she will stay awake during the middle of night. There stopped the experiment.
