holography goes quantum?

We present experiments on information encoding using nanoscale writing with degenerate two-dimensional electrons. We show “pages” (letters encoded at specific energies) materialized by precisely engineering electron scattering environments with the tip of a scanning tunneling microscope. We then demonstrate that multiple pages can be encoded into the same region of space, using energy as a third holographic dimension. | electronic nanoholography

einstein, morgenstern and their dear friend gödel

nicenicenice materials collected by jeffrey kegler, who got hold of a document written by morgenstern that proofs at least that gödel found a kind of contradiction in the us constitution, yet nobody knows what it was. there are a lot of schnurren in morgenstern's memo about gödel as well as einstein.

morgenstern recalls a scene in with einstein was asked for an "authograph".

i turned to einstein and said: "it must be dreadful to be persecuted in this fashion by so many people." einstein said to me: you know, that is just the last remnant of cannibalism." i was puzzled and said, "how is that?" he said: "yes, formerly they wanted your blood, now they want your ink." | oskar morgenstern, history of the naturalization of kurt gödel
