QUES: In 1930, Paul Dirac proposed a model of the vacuum as an infinite sea of particles possessing negative energy, called the Dirac sea. This theory helped refine the predictions of his earlier formulated Dirac equation, and successfully predicted the existence of the positron, confirmed two years later. Werner Heisenberg's uncertainty principle formulated in 1927, predict a fundamental limit within which instantaneous position and momentum, or energy and time can be measured. This has far reaching consequences on the "emptiness" of space between particles. In the late 20th century, so-called virtual particles that arise spontaneously from empty space were confirmed.
What kind of energy did Werner Heisenberg believe a vacuum held?

ANS: unanswerable

QUES: The first record of the name Israel (as ysrir) occurs in the Merneptah stele, erected for Egyptian Pharaoh Merneptah c. 1209 BCE, "Israel is laid waste and his seed is not." This "Israel" was a cultural and probably political entity of the central highlands, well enough established to be perceived by the Egyptians as a possible challenge to their hegemony, but an ethnic group rather than an organised state; Ancestors of the Israelites may have included Semites native to Canaan and the Sea Peoples. McNutt says, "It is probably safe to assume that sometime during Iron Age a population began to identify itself as 'Israelite'", differentiating itself from the Canaanites through such markers as the prohibition of intermarriage, an emphasis on family history and genealogy, and religion.
When does the first record of the name Israel occurs?

ANS: Merneptah stele

QUES: Following various military conquests in the Greek East, Romans adapted a number of Greek educational precepts to their own fledgling system. They began physical training to prepare the boys to grow as Roman citizens and for eventual recruitment into the army. Conforming to discipline was a point of great emphasis. Girls generally received instruction from their mothers in the art of spinning, weaving, and sewing. Schooling in a more formal sense was begun around 200 BC. Education began at the age of around six, and in the next six to seven years, boys and girls were expected to learn the basics of reading, writing and counting. By the age of twelve, they would be learning Latin, Greek, grammar and literature, followed by training for public speaking. Oratory was an art to be practiced and learnt, and good orators commanded respect.[citation needed]
What caused the Romans to conform several educational concepts to their own system?

ANS:
various military conquests in the Greek East
