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 Man… - Oliver Sacks

We had a large old-fashioned battery, a wet cell, in the kitchen, hooked up to an electric bell. The bell was too complicated to understand at first, and the battery, to my mind, was more immediately attractive, for it contained an earthenware tube with a massive, gleaming copper cylinder in the middle, immersed in a bluish liquid, all this inside an outer glass casing, also filled with fluid, and containing a slimmer bar of zinc. It looked like a miniature chemical factory of sorts, and I thought I saw little bubbles of gas, at times, coming off the zinc. The Daniell cell (as it was called) had a thoroughly nineteenth-century, Victorian look about it, and this extraordinary object was making electricity all by itself—not by rubbing or friction, but just by the virtue of its own chemical reactions.

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.)

I never heard [my parents] talk between themselves about Palestine or Zionism, and I suspected they had no strong convictions on the subject, at least until after the war, when the horror of the Holocaust made them feel there should be a “National Home.” I felt they were bullied by the organizers of these meetings, and by the gangsterlike evangelists who would pound at the front door and demand large sums for yeshivas or “schools in Israel.” My parents, clearheaded and independent in most other ways, seemed to become soft and helpless in the face of these demands, perhaps driven by a sense of obligation or anxiety. My own feelings […] were passionately negative: I came to hate Zionism and evangelism and politicking of every sort, which I regarded as noisy and intrusive and bullying.
