LETTER FROM POLAND: Travelling around Polish spacetime
                                
                                
                                
                                    
                                
                                
  
    
                                
                                    This week's Letter suggests that travelling around Poland, we can really travel backwards and forwards in time, as well as space. Rapid social and technological changes are happening faster in some places, slower in others. Perhaps time itself moves faster or slower depending on where you are.
