What a great way for the Catholic church to show that it is no longer hostile to science. Yeah right.
Is that the plan? 'Look! look everyone! Not only are we a big friendly welcomimg Church, we're so accommodating of science that we can exhibit the work of a heretic we literally brought to his knees before the might of Mother Church, and came within a whisker of burning for allowing his observations of reality to contradict official doctrine. A man whom we finally decided was telling the truth in 1992, by which time his theories and observations had been superseded by extremely advanced theories about the nature of reality. Unfortunately for us though, these theories were developed by people we couldn't cow into submission with the explicit threat of torture and execution. Aren't we all nice and modern?'
It occurs to me that these papers and instruments are probably the same ones the Church seized at the time of his trial for heresy, so how thoughtful the Vatican is for allowing these artefacts to go on general display.
