This lemon tree seemed to be dead for a few years, but this morning I found out that it just grew some leaves, greened some branches, and even sprouted a pink bud.

Yet another thing in my life which seemed to be dead and then came back to life.
(If you know how to determine if a plant is dead or alive biologically, ping me.)

I created a very simple key-frame animation via layers with Procreate; more to come.

Electric power flow

After installing Tesla solar panel and power-wall last month, I have been watching the daily power flows among the grid, solar, home, and battery with intrigue.
With weather forecast, I can imagine programming the electric system to optimize the schedules of home appliance usage (e.g., laundry when the sun is bright) and charging from the grid (e.g., backup for an incoming power outage).

I started with vector drawings to enforce simplicity and moved on to raster sketches for better expressibility.

Church-state separation

Why the US is celebrating Easter, a Christian holiday, but not holidays of other regions or cultures, such as Holi, Ramadan, or Passover?

What does it mean for a non-Christian to put her hand on a holy Bible in a state ritual like court oath or citizenship ceremony?

National holidays should be centered on nations (e.g., Independence Day), not religions.

Scaffolding knowledge

Every information is a piece of an entire knowledge, so instead of treating what we learn as separate fragments, it is more effective to memorize and understand them as a whole.
This is possible because knowledge often repeats in different forms, such as through history or books.


In effect, Funes not only remembered every leaf on every tree of every wood, but even every one of the times he had perceived or imagined it.
To think is to forget a difference, to generalize, to abstract. In the overly replete world of Funes there were nothing but details, almost contiguous details.
