This process makes scientific knowledge even more durable. They must throw out the old scientific ideas and disregard the prior evidence, because scientific knowledge should only consider the most recent findings. They must adjust the scientific ideas to account for all of the known evidence. This process makes the scientific knowledge weaker.

Stamps were used in California gold mines around 1850. First developed in England and used by Cornish miners, stamps were heavy iron machines used to pound rocks containing gold quartz into a fine dust so the gold ore could be extracted. Small stamps were commonly powered by water wheels while larger ones ran by steam engines.
