Indians can't think forward by 15 mins: Einstein's diaries

A book compiling Albert Einstein's travel diaries has claimed that the world-renowned scientist believed Indians were "biologically inferior" and were hampered by the subcontinent's climate that "prevented them from thinking backward or forward by more than a quarter of an hour." Caltech author Ze'ev Rosenkranz further quotes Einstein "Wouldn't we too, in this climate, become like the Indians?"
