(a) Hard sudoku puzzles are usually designed for defying our logical reasonings, so we can counter with the Principle of Least Choice (PLC) by selecting the least likely one when facing the multiple choices of our next move. The harder the puzzle, the more often PLC is recommended to be used; (b) This lecture serves as the preface for promoting…[Read more]

The feasibility of treating the Hillcrest Educational Center (HEC) wastewater by a WWT system consisting of septic tank, dissolved air flotation-filtration (DAFF) and leaching field has been studied in three parts: (a) Technically the DAFF treats the HEC septic tank effluent well and removes 91-94% TSS, 40-76% COD, 60-65% BOD, 56-98% P,…[Read more]

Lynn Margulis’s writing about symbiosis has profoundly influenced contemporary evolutionary theory, as well as continental and analytic philosophy of science, the materialist turn, and new materialism. Nonetheless, her work, and all symbiosis or evolution, is founded on a paradox: symbiosis fictionalizes customary accounts of the origin and e…[Read more]
