The first and most enigmatic of the Chinese classics is the Book of Changes, and the reasoning behind its binary hexagram sequence remained an unsolved mystery for some 3,000 years (according to the tradition ascribing it to King Wen of Zhou, d. -11th c.). This Monograph resolves the classical enigma: Richard Cook provides a comprehensive analysis of the hexagram sequence, showing that its classification of binary sequences demonstrates knowledge of the convergence of certain linear recurrence sequences (LRS; Pingala -5th c.?, Fibonacci 1202) to division in extreme and mean ratio (DEMR, the ÒGolden SectionÓ irrational; Pythagoras -6th c.?, Euclid -4th c.). It is shown that the complex hexagram sequence encapsulates a careful and ingenious demonstration of the LRS/DEMR relation, that this knowledge results from general combinatorial analysis, and is reflected in elements emphasized in ancient Chinese and Western mathematical traditions.

Pre-Portioned Sachets That Calm Itch and Hydrate
Size: 1.47 Ounce (Pack of 1)
These individual sachets make it incredibly easy to prepare a soothing oatmeal bath when your skin is dealing with itching, dryness, or reactivity. I recently had an allergic reaction that left me with intensely itchy hives across my body, and I was willing to try anything that might help. I picked this up because it was reasonably priced, and it ended up being a great decision. The powder sprinkles smoothly into running bath water and begins to work quickly to calm the skin. Even though it is a powder, it forms only minimal clumps, and any that do appear are easy to break apart with your fingers. My skin felt noticeably more hydrated and far less irritated after soaking, and I was pleasantly surprised that it didn’t leave any residue behind in the tub. The pre-portioned sachets make the whole process simple and mess-free, which is especially helpful when you’re already uncomfortable. I’ll definitely be keeping these on hand for times when my skin needs extra TLC.
