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.
What year was the uncertainty principle formed?
1927,

23-year-old Candice Glover won the season with Kree Harrison taking the runner-up spot. Glover is the first female to win American Idol since Jordin Sparks. Glover released "I Am Beautiful" as a single while Harrison released "All Cried Out" immediately after the show. Glover sold poorly with her debut album, and this is also the first season that the runner-up was not signed by a music label.

The Tuvaluan language and English are the national languages of Tuvalu. Tuvaluan is of the Ellicean group of Polynesian languages, distantly related to all other Polynesian languages such as Hawaiian, Māori, Tahitian, Samoan and Tongan. It is most closely related to the languages spoken on the Polynesian outliers in Micronesia and northern and central Melanesia. The language has borrowed from the Samoan language, as a consequence of Christian missionaries in the late 19th and early 20th centuries being predominantly Samoan.
From what language does Tuvaluan borrow many linguistic traits?
Samoan
