Problem: Time:

Time appears to have a directionthe past lies behind, fixed and immutable, while the future lies ahead and is not necessarily fixed. Yet for the most part the laws of physics do not specify an arrow of time, and allow any process to proceed both forward and in reverse. This is generally a consequence of time being modeled by a parameter in the system being analyzed, where there is no "proper time": the direction of the arrow of time is sometimes arbitrary. Examples of this include the Second law of thermodynamics, which states that entropy must increase over time (see Entropy); the cosmological arrow of time, which points away from the Big Bang, CPT symmetry, and the radiative arrow of time, caused by light only traveling forwards in time (see light cone). In particle physics, the violation of CP symmetry implies that there should be a small counterbalancing time asymmetry to preserve CPT symmetry as stated above. The standard description of measurement in quantum mechanics is also time asymmetric (see Measurement in quantum mechanics).

The violation of what implies that there should be a small counterbalancing difection asymmetry?

Problem: Hydrogen, as atomic H, is the most abundant chemical element in the universe, making up 75% of normal matter by mass and over 90% by number of atoms (most of the mass of the universe, however, is not in the form of chemical-element type matter, but rather is postulated to occur as yet-undetected forms of mass such as dark matter and dark energy). This element is found in great abundance in stars and gas giant planets. Molecular clouds of H2 are associated with star formation. Hydrogen plays a vital role in powering stars through the proton-proton reaction and the CNO cycle nuclear fusion.
Clouds of H2 form what?

Answer: stars

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
Integral to the story of the origin of the name "Antarctica" is how it was not named Terra Australisthis name was given to Australia instead, and it was because of a mistake made by people who decided that a significant landmass would not be found farther south than Australia. Explorer Matthew Flinders, in particular, has been credited with popularizing the transfer of the name Terra Australis to Australia. He justified the titling of his book A Voyage to Terra Australis (1814) by writing in the introduction:
What was Flinder Matthews credited with?
A: unanswerable

Context and question: Popper coined the term "critical rationalism" to describe his philosophy. Concerning the method of science, the term indicates his rejection of classical empiricism, and the classical observationalist-inductivist account of science that had grown out of it. Popper argued strongly against the latter, holding that scientific theories are abstract in nature, and can be tested only indirectly, by reference to their implications. He also held that scientific theory, and human knowledge generally, is irreducibly conjectural or hypothetical, and is generated by the creative imagination to solve problems that have arisen in specific historico-cultural settings.
What did Popper think could be tested only directly?
Answer: unanswerable

Question: In the 16th century, Count Hieronymus Schlick of Bohemia began minting coins known as Joachimstalers (from German thal, or nowadays usually Tal, "valley", cognate with "dale" in English), named for Joachimstal, the valley where the silver was mined (St. Joachim's Valley, now Jachymov; then part of the Kingdom of Bohemia, now part of the Czech Republic). Joachimstaler was later shortened to the German Taler, a word that eventually found its way into Danish and Swedish as daler, Norwegian as dalar and daler, Dutch as daler or daalder, Ethiopian as (talari), Hungarian as taller, Italian as tallero, and English as dollar. Alternatively, thaler is said to come from the German coin Guldengroschen ("great guilder", being of silver but equal in value to a gold guilder), minted from the silver from Joachimsthal.
Is there an answer to this question: What is the modern name for Joachimsthal?

Answer: unanswerable

Problem: North Carolina:

The climate of the coastal plain is influenced by the Atlantic Ocean, which keeps conditions mild in winter and moderate, although humid, in summer. The highest coastal, daytime temperature averages less than 89 F (32 C) during summer months. The coast has mild temperatures in winter, with daytime highs rarely below 40 F (4 C). The average daytime temperature in the coastal plain is usually in the mid-50s F (1114 C) in winter. Temperatures in the coastal plain only occasionally drop below the freezing point at night. The coastal plain averages only around 1 inch (2.5 cm) of snow or ice annually, and in many years, there may be no snow or ice at all.

What is the climate of North Carolinas coastal plain in the summer?

A:
moderate, although humid
