II have always had an interest in theatrical productions so what better than to link the science and arts, yes real STREAM. I always maintain that this material is not for reading but for performing to the class/on stage/assembly etc. Although it went down like a lead balloon to the class, it was always enjoyable to do and gives the teacher that notoriety of the ECCENTRIC, which makes it stick in the minds of students.
My favourite section of the Primo Levi's Periodic Table
33 The first day it was my fate to be assigned the preparation of zinc sulfate: it should not have been too difficult; it was a matter of making an elementary stoichiometric calculation and attacking the zinc particles with previously diluted sulfuric acid: concentrate, crystallize, dry with the pump, wash and recrystallize. Zinc, Zinck, zinco; they make tubs out of it for laundry, it is not an element which says much to the imagination, it is gray and its salts are colorless, it is not toxic, nor does it produce striking chromatic reactions; in short, it is a boring metal. It has been known to humanity [outside India!] for two or three centuries, so it is not a veteran covered with glory like copper, nor even of those newly minted elements which are still surrounded with the glamour of their discovery.
Caselli handed me my zinc; I returned to the bench and prepared to work: I felt curious, shy, and vaguely annoyed, as when you reach thirteen and must go to the temple to recite in Hebrew the Bar Mitzvah prayer before the rabbi; the moment, desired and somewhat feared, had come. The hour of the appointment with Matter, the Spirit’s great antagonist, had struck: hyle, which, strangely, can be found embalmed in the endings of alkyl radicals: methyl, butyl, etc...
The course notes contained a detail which at first reading had escaped me, namely, that the so tender and delicate zinc, so yielding to acid which gulps it down in a single mouthful, behaves, however, in a very different fashion when it is very pure: then it obstinately resists the attack. One could draw from this two conflicting philosophical conclusions: the praise of purity, which protects from evil like a coat of mail; the praise of impurity, which gives rise to changes, in other words, to life. I discarded the first, disgustingly moralistic, and I lingered to consider the second, which I found more congenial. In order for the wheel to turn, for life to be lived, impurities are needed, and the impurities of impurities in the soil, too, as is known, if it is to be fertile. Dissension, diversity, the grain of salt and mustard are needed: Fascism does not want them, forbids them, and that’s why you are not a Fascist; it wants everybody to be the same, and you are not. But immaculate virtue does not exist either, or if it exists it is detestable. So take the solution of copper sulfate which is in the shelf of reagents, add a drop of it to your sulfuric acid, and you’ll see the reaction begin: the zinc wakes up, it is covered with a white fur of hydrogen bubbles, and there you are, the enchantment has taken place, you can leave it to its fate and take a stroll around the lab and see what’s new and what the others are doing...
