4. Hot Cracking Phenomena & Eureka Encounters
Many failure analysts will agree that in some difficult cases one might look at a fracture for
weeks without being able to arrive at a plausible conclusion. It is all the more exhilarating
in these cases to finally see the light. Archimedes called out "Eureka!" when he found the
principle later named after him. What is more, rumour has it he jumped out of his bathtub
and ran around Syracuse stark naked, continuing to shout "Eureka!" which is Greek and
means "| have found!" Some modern failure analysts might still call out "Eureka!" from time
to time. However, nowadays they try to avoid the naked part.
