I think you&#x27;re actually proving Kuhn&#x27;s point when he argues that the progress of science involves wiping out almost all memory of obsolete paradigms. When we read a science textbook, all of the information is placed within the structure of the current paradigm, as if none other came before it.<p>To give an example, how much do you know about theories of geology before 1960?  Any educated person today knows the basic idea of plate tectonics, but only a historian of science might know what came before.<p>According to Kuhn, the impression you get that &quot;puzzle pieces are rarely removed&quot; is something that happens after science has been rewritten to fit a new paradigm.
