One of the simplest methods for beating procrastination in almost any task was inspired by busy waiters.

It’s called the Zeigarnik effect after a Russian psychologist, Bluma Zeigarnik (above left), who noticed an odd thing while sitting in a restaurant in Vienna. The waiters seemed only to remember orders which were in the process of being served. When completed, the orders evaporated from their memory.

She asked participants to do twenty or so simple little tasks in the lab, like solving puzzles and stringing beads (Zeigarnik, 1927). Except some of the time they were interrupted half way through the task. Afterwards she asked them which activities they remembered doing.

The most beautiful thing about it is how elegant these electronic components are. They each contain very few materials and mechanisms, but demonstrate a tremendous understanding of the physical world.
