My own first love was biology. I spent a great part of my adolescence in the Natural History museum in London (and I still go to the Botanic Garden a… - Oliver Sacks

A spectacular anomaly came up with the hydrides of the nonmetals—an ugly bunch, about as inimical to life as one could get. Arsenic and antimony hydrides were very poisonous and smelly; silicon and phosphorous hydrides were spontaneously inflammable. I had made in my lab the hydrides of sulfur (H₂S), selenium (H₂Se), and tellurium (H₂Te), all Group VI elements, all dangerous and vile-smelling gases. The hydride of oxygen, the first Group VI element, one might predict by analogy, would be a foul-smelling, poisonous, inflammable gas, too, condensing to a nasty liquid around −100°C. And instead it was water, H₂O—stable, potable, odorless, benign, and with a host of special, indeed unique properties (its expansion when frozen, its great heat capacity, its capacity as an ionizing solvent, etc.) which made it indispensable to our watery planet, indispensable to life itself. What made it such an anomaly? […] (This question, I found, had only been resolved recently, in the 1930s, with Linus Pauling's delineation of the hydrogen bond.)

During the war the congregation was largely broken up […] and it was never really reconstituted after the war. […] Before the war my parents (I, too) had known almost every shop and shopkeeper in Cricklewood […] and I would see them all in their places in shul. But all this was shattered with the impact of the war, and then with the rapid postwar social changes in our corner of London. I myself, traumatized at Braefield, had lost touch with, lost interest in, the religion of my childhood. I regret that I was to lose it as early and as abruptly as I did, and this feeling of sadness or nostalgia was strangely admixed with a raging atheism, a sort of fury with God for not existing, not taking care, not preventing the war, but allowing it, and all its horrors, to occur.

And I often dream of chemistry at night, dreams that conflate the past and the present, the grid of the periodic table transformed to the grid of Manhattan. […] Sometimes, too, I dream of the indecipherable language of tin (a confused memory, perhaps, of its plaintive “cry”). But my favorite dream is of going to the opera (I am Hafnium), sharing a box at the Met with the other heavy transition metals—my old and valued friends—Tantalum, Rhenium, Osmium, Iridium, Platinum, Gold, and Tungsten.
