Recreating (and advancing) pk’s censored domains:
Knatz.com / Teaching / Thinking Tools / Spectra /
A lot of materials on spectra got posted at Macroinformation.org, some of that got recreated at the Macroinformation blog, but should be moved here: under Thinking Tools / Information / Macroinformation / But a great deal on spectra belongs right here: primarily as spectra, secondarily as information.
Uh oh, this is supposed to be a menu: I’ll fix.
