In 1807, Thomas Young was possibly the first to use the term "energy" instead of vis viva, in its modern sense. Gustave-Gaspard Coriolis described "kinetic energy" in 1829 in its modern sense, and in 1853, William Rankine coined the term "potential energy". The law of conservation of energy was also first postulated in the early 19th century, and applies to any isolated system. It was argued for some years whether heat was a physical substance, dubbed the caloric, or merely a physical quantity, such as momentum. In 1845 James Prescott Joule discovered the link between mechanical work and the generation of heat.

Ah, so.. unanswerable

A key aspect of the Gates Foundation's U.S. efforts involves an overhaul of the country's education policies at both the K-12 and college levels, including support for teacher evaluations and charter schools and opposition to seniority-based layoffs and other aspects of the education system that are typically backed by teachers' unions. It spent $373 million on education in 2009. It has also donated to the two largest national teachers' unions. The foundation was the biggest early backer of the Common Core State Standards Initiative.

Most records at NARA are in the public domain, as works of the federal government are excluded from copyright protection. However, records from other sources may still be protected by copyright or donor agreements. Executive Order 13526 directs originating agencies to declassify documents if possible before shipment to NARA for long-term storage, but NARA also stores some classified documents until they can be declassified. Its Information Security Oversight Office monitors and sets policy for the U.S. government's security classification system.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): Most of NARA's holdings are available to sector?
Ah, so..
public domain
