In April 2009, the United States Supreme Court agreed to hear a suit over reverse discrimination brought by 20 white and Hispanic firefighters against the city. The suit involved the 2003 promotion test for the New Haven Fire Department. After the tests were scored, no blacks scored high enough to qualify for consideration for promotion, so the city announced that no one would be promoted. On 29 June 2009, the United States Supreme Court ruled in favor of the firefighters, agreeing that they were improperly denied promotion because of their race. The case, Ricci v. DeStefano, became highly publicized and brought national attention to New Haven politics due to the involvement of then-Supreme Court nominee (and Yale Law School graduate) Sonia Sotomayor in a lower court decision.
The actual name for the case was what?
Ricci v. DeStefano

In 1930, Paul Dirac proposed a model of the vacuum as an infinite sea of particles possessing negative energy, called the Dirac sea. This theory helped refine the predictions of his earlier formulated Dirac equation, and successfully predicted the existence of the positron, confirmed two years later. Werner Heisenberg's uncertainty principle formulated in 1927, predict a fundamental limit within which instantaneous position and momentum, or energy and time can be measured. This has far reaching consequences on the "emptiness" of space between particles. In the late 20th century, so-called virtual particles that arise spontaneously from empty space were confirmed.
When werer virtual particles confirmed?
late 20th century

The structure known as "Virgil's tomb" is found at the entrance of an ancient Roman tunnel (also known as "grotta vecchia") in Piedigrotta, a district two miles from the centre of Naples, near the Mergellina harbor, on the road heading north along the coast to Pozzuoli. While Virgil was already the object of literary admiration and veneration before his death, in the Middle Ages his name became associated with miraculous powers, and for a couple of centuries his tomb was the destination of pilgrimages and veneration.
During which time period did Virgil's name become associated with miraclous powers?
Middle Ages
