In a new essay at theNew York Times , a prof of astrophysics at the University of Rochester asks the retro - futurist ’s most daunting interrogation : Where ’s my flying railway car ?
Or , as Adam Frank ’s piece of music is titled , “ I Was promise Flying Cars . ”
you’re able to interpret his entire essay about why he think we do n’t have fly cars at theNew York Times . The short version : Frank argues that we do n’t interpret soberness well enough .
