>time
>length
>mass
>temperature

whats the effects of communism on science?
the ussr was a big communist country for most of the 20th century, was soviet or warsaw pact science better or worse than western science?
it seems like communism should be very good for science since communism has central planning and it makes religion illegal, but somehow or other the west kept pace with the soviets pretty good during the 20th century regardless the obvious advantages of communism. is there a scientific explanation for that?
