Problem: A third type of solution to the problem of the direction of time, although much less represented, argues that the laws are not time-reversal symmetric. For example, certain processes in quantum mechanics, relating to the weak nuclear force, are not time-reversible, keeping in mind that when dealing with quantum mechanics time-reversibility comprises a more complex definition. But this type of solution is insufficient because 1) the time-asymmetric phenomena in quantum mechanics are too few to account for the uniformity of macroscopic time-asymmetry and 2) it relies on the assumption that quantum mechanics is the final or correct description of physical processes.[citation needed]

Problem: The concept's origins can potentially be traced back further. Jewish law includes several considerations whose effects are similar to those of modern intellectual property laws, though the notion of intellectual creations as property does not seem to exist notably the principle of Hasagat Ge'vul (unfair encroachment) was used to justify limited-term publisher (but not author) copyright in the 16th century. In 500 BCE, the government of the Greek state of Sybaris offered one year's patent "to all who should discover any new refinement in luxury".

Problem: Melbourne is an international cultural centre, with cultural endeavours spanning major events and festivals, drama, musicals, comedy, music, art, architecture, literature, film and television. The climate, waterfront location and nightlife make it one of the most vibrant destinations in Australia. For five years in a row (as of 2015) it has held the top position in a survey by The Economist Intelligence Unit of the world's most liveable cities on the basis of a number of attributes which include its broad cultural offerings. The city celebrates a wide variety of annual cultural events and festivals of all types, including Australia's largest free community festivalMoomba, the Melbourne International Arts Festival, Melbourne International Film Festival, Melbourne International Comedy Festival and the Melbourne Fringe Festival. The culture of the city is an important drawcard for tourists, of which just under two million international overnight visitors and 57.7 million domestic overnight visited during the year ending March 2014.
How many domestic overnight visitors came to Melbourne during the year ending March 2014?
