the mid-21st century, Asimov did not anticipate the development of transistors; the chronoscope apparently uses vacuum tube technology since it needs a short time to warm up. On the other hand, it might be said that he did accurately predict the effects of the development of cheap and common video recording equipment, from some people's obsessive viewing of recordings of deceased loved ones to the possibility that ubiquitous surveillance may end privacy as it currently exists. The name Araman is similar to the character in the story "The Last Trump", "R. E. Mann" (a pun on Ahriman). The Asimov festschrift Foundation's Friends includes a sequel to "The Dead Past" by American science fiction writer Barry N. Malzberg called "The Present Eternal". The story is referenced in Alex Kozinski's article for his April 2012 Stanford Law Review article on internet privacy and internet surveillance. Asimov made up the science of "neutrinics", the detection and manipulation of the neutrino particle, to explain how the chronoscope functions. Although the existence of the neutrino had been postulated in 1930, the first confirmed report of its detection was published a few months after the story first appeared. Canadian Historian Bernard Wheatley referred to Asimov's story at a conference, saying: "Asimov's story assumes that the government could keep up for several decades the hoax that it has a machine capable of viewing the distant past, without ever producing a single such photo. That is not possible—historians would have smelled a rat long before! Medievalists, Classicists, experts on each and every period of history, would have clamored very loudly for a photo, any genuine photo, of their period. How much we could have learned from such a photo, even if it was just of daily life on an ordinary day when nothing special happened! There would have been no possibility for the government to fake a photo—the best experts on the period in question would have looked minutely at the smallest detail. No fake could survive such scrutiny. And if the government persisted in producing no photos, the historians would have soon enough concluded that there just were no photos."
