Question: Lie groups are of fundamental importance in modern physics: Noether's theorem links continuous symmetries to conserved quantities. Rotation, as well as translations in space and time are basic symmetries of the laws of mechanics. They can, for instance, be used to construct simple models—imposing, say, axial symmetry on a situation will typically lead to significant simplification in the equations one needs to solve to provide a physical description.v[›] Another example are the Lorentz transformations, which relate measurements of time and velocity of two observers in motion relative to each other. They can be deduced in a purely group-theoretical way, by expressing the transformations as a rotational symmetry of Minkowski space. The latter serves—in the absence of significant gravitation—as a model of space time in special relativity. The full symmetry group of Minkowski space, i.e. including translations, is known as the Poincaré group. By the above, it plays a pivotal role in special relativity and, by implication, for quantum field theories. Symmetries that vary with location are central to the modern description of physical interactions with the help of gauge theory.
Is there an answer to this question: What describe the complete symmetry group of Minkowski space including translations?

Answer: Poincaré group


Question: Other notable places include Elizabeth Fort, the Cork Opera House, Christ Church on South Main Street (now the Triskel Arts Centre and original site of early Hiberno-Norse church), St Mary's Dominican Church on Popes Quay and Fitzgerald's Park to the west of the city, which contains the Cork Public Museum. Other popular tourist attractions include the grounds of University College Cork, through which the River Lee flows, the Women's Gaol at Sundays Well (now a heritage centre) and the English Market. This covered market traces its origins back to 1610, and the present building dates from 1786.
Is there an answer to this question: What is the Cork Opera House the original site of?

Answer: unanswerable


Question: The gates of the Temple of Jerusalem used Corinthian bronze made by depletion gilding. It was most prevalent in Alexandria, where alchemy is thought to have begun. In ancient India, copper was used in the holistic medical science Ayurveda for surgical instruments and other medical equipment. Ancient Egyptians (~2400 BC) used copper for sterilizing wounds and drinking water, and later on for headaches, burns, and itching. The Baghdad Battery, with copper cylinders soldered to lead, dates back to 248 BC to AD 226 and resembles a galvanic cell, leading people to believe this was the first battery; the claim has not been verified.
Is there an answer to this question: What is the name of the battery that was developed using copper in 248 BC?

Answer: Baghdad Battery


Question: Similar examples abound. Macedonian, although mutually intelligible with Bulgarian, certain dialects of Serbian and to a lesser extent the rest of the South Slavic dialect continuum, is considered by Bulgarian linguists to be a Bulgarian dialect, in contrast with the contemporary international view and the view in the Republic of Macedonia, which regards it as a language in its own right. Nevertheless, before the establishment of a literary standard of Macedonian in 1944, in most sources in and out of Bulgaria before the Second World War, the southern Slavonic dialect continuum covering the area of today's Republic of Macedonia were referred to as Bulgarian dialects.
Is there an answer to this question: In what year was a Macedonian literary standard established?

Answer:
1944
