Quantum Physics

A non-mys­te­ri­ous in­tro­duc­tion to quan­tum me­chan­ics, in­tended to be ac­cessible to any­one who can grok alge­bra and com­plex num­bers. Clean­ing up the old con­fu­sion about QM is used to in­tro­duce ba­sic is­sues in ra­tio­nal­ity (such as the tech­ni­cal ver­sion of Oc­cams Ra­zor), episte­mol­ogy, re­duc­tion­ism, nat­u­ral­ism, and philos­o­phy of sci­ence. Not dis­pens­able read­ing, even though the ex­act rea­sons for the di­gres­sion are hard to ex­plain in ad­vance of read­ing.
