Bill Callahan - Live at Sixth and I
Very excited that npr music shared a full length recording of Bill Callahan’s concert back on October 2nd.
It took place at the beautiful Sixth & I historical synagogue in Washington DC. I was there! And I loved this concert. So much I’m still spellbound weeks later as if I’d just been there.
Very happy I can keep my memory alive with this little keepsake. It was the first time I’ve seen him live in concert.
Franz Kafka is 130
On the occasion of Franz Kafka’s 130th birthday (yesterday), here are two of my favorite short stories!
Rejection Translated by Willa and Edwin Muir
When I meet a pretty girl and beg her: ‘Be so good as to come with me,’ and she walks past without a word, this is what she means to say:
‘You are no Duke with a famous name, no broad American with a Red Indian figure, level, brooding eyes and a skin tempered by the air of the prairies and the rivers that flow through them, you have never journeyed to the seven seas and voyaged on them wherever they may be, I don’t know where.
Collection of functions and identities to help my memory in a few courses I’m taking.
Musical Möbius Strip
Fascinating: The Musical Offering by Johann Sebastian Bach (BWV 1079) contains a Crab canon that can not only be played forward and backwards, but also forward and backwards simultaneously, here visualized on a Möbius strip.
Zequals and the Art of Estimation
This Numberphile video is about Zequals which can be useful if you need to compute a quick estimate, for example to find out if your calculation is on the right track.
The idea is to ruthlessly round every number to just one significant digit. For example:
3 * 7 = 21 zz 20 7 * 8 = 56 zz 60 436 * 68 zz 400 * 70 = 28000 zz 30000 The actual answer is 29648 and surprisingly close to the zequal-result.
