Napoleon's coronation took place on December 2, 1804. Two separate crowns were brought for the ceremony: a golden laurel wreath recalling the Roman Empire and a replica of Charlemagne's crown. Napoleon entered the ceremony wearing the laurel wreath and kept it on his head throughout the proceedings. For the official coronation, he raised the Charlemagne crown over his own head in a symbolic gesture, but never placed it on top because he was already wearing the golden wreath. Instead he placed the crown on Josephine's head, the event commemorated in the officially sanctioned painting by Jacques-Louis David. Napoleon was also crowned King of Italy, with the Iron Crown of Lombardy, at the Cathedral of Milan on May 26, 1805. He created eighteen Marshals of the Empire from amongst his top generals to secure the allegiance of the army.
On what date did Napoleon's coronation occur?
****
The answer: December 2, 1804

CDs are susceptible to damage during handling and from environmental exposure. Pits are much closer to the label side of a disc, enabling defects and contaminants on the clear side to be out of focus during playback. Consequently, CDs are more likely to suffer damage on the label side of the disc. Scratches on the clear side can be repaired by refilling them with similar refractive plastic or by careful polishing. The edges of CDs are sometimes incompletely sealed, allowing gases and liquids to corrode the metal reflective layer and to interfere with the focus of the laser on the pits. The fungus Geotrichum candidum, found in Belize, has been found to consume the polycarbonate plastic and aluminium found in CDs.
How are scratches on a CD fixed?

The answer:
refilling them with similar refractive plastic or by careful polishing
