benham's top... how does it work? (19/365e)


Nina came over this morning and we sat downstairs and were cold whenever the living room door opened.

The kids did their homework in a blanket fort under the table and it took sooo very long again .

Henry hot glue gunned a cd to a bottle top and we stuck it on a dowel to make a spinning top to demonstrate The Fechner color effect ... we printed various versions of Benham's top and I used the sharpie to make it really really black - it is pretty cool!

all the colors of the rainbow


I talked to Bruno during the day (unusual) about Spiegel im Spiegel im spiegel - supposedly there is an algorithm for creating "opposite" or "reflected" music, more than just playing something "backwards"

Jack pumpkinhead again

I practiced in the evening with henry on cello, playing the duet bass line on viola, and it was sounding very good. and i played a lot of bach on the piano – from pauli... not really a "lot" in terms of music, but a "lot" in terms of time. i spent a few hours on the first few lines of one of the goldberg variation that he had printed an extra copy of and left here. i had fun highlighting the four different parts, but it is nearly impossible for me to play yet.
