One Saturday afternoon in 1933; Warsaw, Einstein exited his portal & casually strolls up the street tipping his hat to various passing ladies; buying a cigar from the last Italian living on the block; the thugs from Grupo 13 want to know about this mystery man who signs his name Albert Magus in the hotel registry the last luxury hotel in Warzawa where he takes his ****** is booked with diplomatic dignitaries; they need know nothing of the time-traveller whose movements can't be traced & who leaves no trace behind although time has been markedly altered it remains seamless; back at Princeton Einstein contemplates that as he can go back & forth in time he should be able to go up & down in scale; that is to become monstrously large or ever infinitesimally small .
