Matter may be converted to energy (and vice versa), but mass cannot ever be destroyed; rather, mass/energy equivalence remains a constant for both the matter and the energy, during any process when they are converted into each other. However, since is extremely large relative to ordinary human scales, the conversion of ordinary amount of matter (for example, 1 kg) to other forms of energy (such as heat, light, and other radiation) can liberate tremendous amounts of energy (~ joules = 21 megatons of TNT), as can be seen in nuclear reactors and nuclear weapons. Conversely, the mass equivalent of a unit of energy is minuscule, which is why a loss of energy (loss of mass) from most systems is difficult to measure by weight, unless the energy loss is very large. Examples of energy transformation into matter (i.e., kinetic energy into particles with rest mass) are found in high-energy nuclear physics.
Matter can't be converted to what?
A: unanswerable

Arthur M. Diamond argues Hayek's problems arise when he goes beyond claims that can be evaluated within economic science. Diamond argued that: "The human mind, Hayek says, is not just limited in its ability to synthesize a vast array of concrete facts, it is also limited in its ability to give a deductively sound ground to ethics. Here is where the tension develops, for he also wants to give a reasoned moral defense of the free market. He is an intellectual skeptic who wants to give political philosophy a secure intellectual foundation. It is thus not too surprising that what results is confused and contradictory."
Who criticizes Hayek's ability to provide specific facts?
A: Arthur M. Diamond

In 1870, Charles Taze Russell and others formed a group in Pittsburgh, Pennsylvania, to study the Bible. During the course of his ministry, Russell disputed many beliefs of mainstream Christianity including immortality of the soul, hellfire, predestination, the fleshly return of Jesus Christ, the Trinity, and the burning up of the world. In 1876, Russell met Nelson H. Barbour; later that year they jointly produced the book Three Worlds, which combined restitutionist views with end time prophecy. The book taught that God's dealings with humanity were divided dispensationally, each ending with a "harvest," that Christ had returned as an invisible spirit being in 1874 inaugurating the "harvest of the Gospel age," and that 1914 would mark the end of a 2520-year period called "the Gentile Times," at which time world society would be replaced by the full establishment of God's kingdom on earth. Beginning in 1878 Russell and Barbour jointly edited a religious journal, Herald of the Morning. In June 1879 the two split over doctrinal differences, and in July, Russell began publishing the magazine Zion's Watch Tower and Herald of Christ's Presence, stating that its purpose was to demonstrate that the world was in "the last days," and that a new age of earthly and human restitution under the reign of Christ was imminent.
1914 would mark the end of a 2520 year period known as what?
A: the Gentile Times

Unaspirated or tenuis consonants are occasionally marked with the modifier letter for unaspiration , a superscript equal sign: t. Usually, however, unaspirated consonants are left unmarked: t.
