Brazil National Museum: as much as 90% of collection destroyed in fire
Building was not insured, the museum’s deputy director said, but some pieces survived including the Bendegó meteorite.

As much as 90% of the collection at Brazil’s National Museum was destroyed in a devastating fire on Sunday and – compounding the disaster – the building was not insured, according to the museum’s deputy director.
Some pieces survived, including the famous Bendegó meteorite and a library of 500,000 books – including works dating back to the days of the Portuguese empire – which was kept in a separate annex, Cristiana Serejo told reporters in front of the building’s blackened shell.
But it was still not possible to say how much of the collection had escaped the flames, Serejo said. “It could be 10%, it could be 15, it could be 20,” she said. “We had a very big loss.”
The museum’s Egyptology collection was completely destroyed, Serejo said.
Researchers who were able to enter one area of the building in Rio de Janeiro are starting to catalogue what little is left, said Serejo, who appealed to members of the public to return any items they found.
Asked if the museum was insured, she screwed up her face in mock anguish, and shook her head.
“I hope we learn from this,” she said. “Other public buildings are in the same situation.”

Opportunity Cost


This phenomenon goes by the name of ‘opportunity cost,’ since by not investing in more equipment and a more rigid production flow, the company is forgoing the opportunity to earn increased profits. These costs are every bite as real as the payment of dollars out-of-pocket.


This notion _______ opportunity cost can be reinforced _________a famous saying ______ Benjamin Franklin, no slouch himself _________ operations management. To make the point, however, we must make a brief excursion into logic. One truth of logic is the validity of the so-called contrapositive, which says simply that if the statement “If A, then B” is true, then it is also true that “If not B, then not A.” That is, of every time A occurs B follows, then we can be sure that if B does not occur, then A did not occur as well. Enough logic then, and back to Ben Franklin.


One of his Poor Richard sayings is that “A penny saved is a penny earned.” We have all recognized the truth of that since childhood, but I assert that by this saying Ben showed us he knows everything about opportunity cost. After all, what is the contrapositive of “A penny not earned is a penny not saved (i.e., a penny sent). All we are saying by this notion of opportunity cost is that “a penny not earned (an opportunity forgone) is a penny spent.” We shall often have occasion to consider opportunity costs, in analyzing and deciding various operations issues.
