Speed-learning thru pk

I'm still quite tired from the weekend. Having a hard time concentrating on quantum mechanics worksheets, I turned the halogen lamp on. This way I could occasionally practice stasis field on the radiometer, when losing focus on learning. I really like it this way - I can do whatever I have to and while doing it, I can still practice pk, as the radiometer is always in the view.

While looking at the radiometer vanes and then back at the paper or worksheet on laptop screen, I often felt this shift-of-focus feeling (which is brain adjusting to the resonant frequency of the spinning vanes). After a couple of minutes glaring at the radiometer, I usually found it easier to continue studying again (it kind of brought me out of the dreamy state that a tired mind keeps falling into).
