Energy gives rise to weight when it is trapped in a system with zero momentum, where it can be weighed. It is also equivalent to mass, and this mass is always associated with it. Mass is also equivalent to a certain amount of energy, and likewise always appears associated with it, as described in mass-energy equivalence. The formula E = mc, derived by Albert Einstein (1905) quantifies the relationship between rest-mass and rest-energy within the concept of special relativity. In different theoretical frameworks, similar formulas were derived by J. J. Thomson (1881), Henri Poincare (1900), Friedrich Hasenohrl (1904) and others (see Mass-energy equivalence#History for further information).
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): In what year did Weinstein create E = mc2?
Ah, so.. unanswerable

Increasing urbanisation of India in 7th and 6th centuries BCE led to the rise of new ascetic or shramana movements which challenged the orthodoxy of rituals. Mahavira (c. 549477 BC), proponent of Jainism, and Buddha (c. 563-483), founder of Buddhism were the most prominent icons of this movement. Shramana gave rise to the concept of the cycle of birth and death, the concept of samsara, and the concept of liberation. Buddha found a Middle Way that ameliorated the extreme asceticism found in the Sramana religions.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): What belief system taught the idea of samsara?
Ah, so.. Shramana

The first six presidents of the United States did not make extensive use of the veto power: George Washington only vetoed two bills, James Monroe one, and John Adams, Thomas Jefferson and John Quincy Adams none. James Madison, a firm believer in a strong executive, vetoed seven bills. None of the first six Presidents, however, used the veto to direct national policy. It was Andrew Jackson, the seventh President, who was the first to use the veto as a political weapon. During his two terms in office, he vetoed twelve billsmore than all of his predecessors combined. Furthermore, he defied the Supreme Court in enforcing the policy of ethnically cleansing Native American tribes ("Indian Removal"); he stated (perhaps apocryphally), "John Marshall has made his decision. Now let him enforce it!"
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): How many bills did George Washington veto?
Ah, so..
two
