@Olivier5,
"experiments" are tests or trials, in the hopes of discovering something . "Controlled experimentation" Is mere methodology. REPEATABLITY is the real desired outcome, wherethe ame data is revealed when sought fter by mny verlapping methods.
I have no religious feelings about history to me, its a "bookkeeping of time like genomic mapping is a bookkeeping of genetics", but like several field and "discovery" based sciences, there are several sub disciplines that are hard sciences applied to history, like geophysics stratigraphy, metallurgy, ceramics , applied thermoluminescence, archeochronology (tree rings, C14) etc. Much of these applied to archeology, which is applied to studies of history (or pre-history).
Most carful studies of historical events ultimatel yield to archeological investigations.
Te METHODS of carrying out historical research are quite often scientific DISCIPLINES, so, by application, history is often a discipline too.
