QUES: In quantum mechanics and quantum field theory, the vacuum is defined as the state (that is, the solution to the equations of the theory) with the lowest possible energy (the ground state of the Hilbert space). In quantum electrodynamics this vacuum is referred to as 'QED vacuum' to distinguish it from the vacuum of quantum chromodynamics, denoted as QCD vacuum. QED vacuum is a state with no matter particles (hence the name), and also no photons. As described above, this state is impossible to achieve experimentally. (Even if every matter particle could somehow be removed from a volume, it would be impossible to eliminate all the blackbody photons.) Nonetheless, it provides a good model for realizable vacuum, and agrees with a number of experimental observations as described next.

What is a QCD?
What is the answer?
ANS: vacuum of quantum chromodynamics,
QUES: Buddhism provides many opportunities for comparative study with a diverse range of subjects. For example, Buddhism's emphasis on the Middle way not only provides a unique guideline for ethics but has also allowed Buddhism to peacefully coexist with various differing beliefs, customs and institutions in countries where it has resided throughout its history. Also, its moral and spiritual parallels with other systems of thoughtfor example, with various tenets of Christianityhave been subjects of close study. In addition, the Buddhist concept of dependent origination has been compared to modern scientific thought, as well as Western metaphysics.

Buddhist concept of dependent origination has been compared to what modern thought?
What is the answer?
ANS: scientific
QUES: Bermuda's pink sand beaches and clear, cerulean blue ocean waters are popular with tourists. Many of Bermuda's hotels are located along the south shore of the island. In addition to its beaches, there are a number of sightseeing attractions. Historic St George's is a designated World Heritage Site. Scuba divers can explore numerous wrecks and coral reefs in relatively shallow water (typically 3040 ft or 912 m in depth), with virtually unlimited visibility. Many nearby reefs are readily accessible from shore by snorkellers, especially at Church Bay.

What are located along the shore of the coral reefs?
What is the answer?
ANS:
unanswerable
