To finance state government operations, Alaska depends primarily on petroleum revenues and federal subsidies. This allows it to have the lowest individual tax burden in the United States. It is one of five states with no state sales tax, one of seven states that do not levy an individual income tax, and one of the two states that has neither. The Department of Revenue Tax Division reports regularly on the state's revenue sources. The Department also issues an annual summary of its operations, including new state laws that directly affect the tax division.

Modern adult contemporary can be a variation of hot AC, and includes modern rock titles in its presentation. In 1997, Mike Marino of KMXB in Las Vegas described the format as reaching "an audience that has outgrown the edgier hip-hop or alternative music but hasn't gotten old and sappy enough for the soft ACs." The format's artists included Alanis Morissette, Counting Crows, Gin Blossoms, Bon Jovi, Train, No Doubt, The Script, The Cranberries, Lifehouse, Sarah McLachlan, Sara Bareilles, John Mayer, Jewel, and Ingrid Michaelson. Unlike modern rock, which went after 18-34 men, this format appealed to women.

What is the sex of the listeners modern rock radio is geared towards?
Answer: men

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 theorized that time and energy can be measured?
Answer:
Werner Heisenberg's uncertainty principle
