So good to see liberal America standing up to the Trumpian threat today. A strange thing happened to me as I followed the topical posts.

Each time I saw the #HandsOff hashtag, what my brain read instead was #Hausdorff, for Felix Hausdorff, the eminent mathematician.

To my shame, I knew nothing about Felix Hausdorff the man. To me as a former Berliner and an emigree to England, Hausdorff sounded like an East Prussian landed-gentry name, I expected a Junker. Wrong. Today I learnt that Felix Hausdorff was in fact Jewish. He, his wife and his sister in law escaped the death camps by suicide, in 1942. (His daughter Lenore survived.) I never knew.

So there really is a hidden connection between today's encouraging #HandsOff news and Felix Hausdorff, the great thinker who was exposed to the same evil of unchecked state power that threatens us today, and against which today's protests took a stance.

Felix Hausdorff - Wikipedia

El 8/Nov/1868 nace el matemático alemán Felix Hausdorff, considerado uno de los fundadores de la topología moderna (entre otras muchas). La topología es rama de las matemáticas que trata de la continuidad y las propiedades de las figuras con independencia a su tamaño y forma. Aplicada a la computación, vendrían siendo las distribuciones de los dispositivos (routers, ordenadores, periféricos, impresoras, etc) y sus distintas conexiones que puede haber en la red
