Tesseract Physics · Daily Book Club
One passage a day, chosen by what the work is wrestling with right now
Every day the PMU lens picks the single most load-bearing passage of Fire Together, Ground Together for what actually shipped in the repo that day, and mails it to the club — with the signed commit panel of the day riding along. This is the public archive: the hook each day led with, and the deep link straight into the book.
