In the late 14th century, in the Grand Duchy of Lithuania, Vytautas the Great reformed the Grand Duchy's army: instead of calling all men to arms, he created forces comprising professional warriorsbajorai ("nobles"; see the cognate "boyar"). As there were not enough nobles, Vytautas trained suitable men, relieving them of labor on the land and of other duties; for their military service to the Grand Duke, they were granted land that was worked by hired men (veldams). The newly formed noble families generally took up, as their family names, the Lithuanian pagan given names of their ennobled ancestors; this was the case with the Gostautai, Radvilos, Astikai, Kesgailos and others. These families were granted their coats of arms under the Union of Horodlo (1413).

Ah, so.. Gostautai,

Alloying copper with tin to make bronze was first practiced about 4000 years after the discovery of copper smelting, and about 2000 years after "natural bronze" had come into general use[citation needed]. Bronze artifacts from the Vinca culture date to 4500 BC. Sumerian and Egyptian artifacts of copper and bronze alloys date to 3000 BC. The Bronze Age began in Southeastern Europe around 37003300 BC, in Northwestern Europe about 2500 BC. It ended with the beginning of the Iron Age, 20001000 BC in the Near East, 600 BC in Northern Europe. The transition between the Neolithic period and the Bronze Age was formerly termed the Chalcolithic period (copper-stone), with copper tools being used with stone tools. This term has gradually fallen out of favor because in some parts of the world the Chalcolithic and Neolithic are coterminous at both ends. Brass, an alloy of copper and zinc, is of much more recent origin. It was known to the Greeks, but became a significant supplement to bronze during the Roman Empire.

Ah, so.. Alloying copper with tin to make bronze

Richard Phillips Feynman was born on May 11, 1918, in Queens, New York City, the son of Lucille (nee Phillips), a homemaker, and Melville Arthur Feynman, a sales manager. His family originated from Russia and Poland; both of his parents were Ashkenazi Jews. They were not religious, and by his youth Feynman described himself as an "avowed atheist". He also stated "To select, for approbation the peculiar elements that come from some supposedly Jewish heredity is to open the door to all kinds of nonsense on racial theory," and adding "... at thirteen I was not only converted to other religious views, but I also stopped believing that the Jewish people are in any way 'the chosen people'." Later in his life, during a visit to the Jewish Theological Seminary, he encountered the Talmud for the first time, and remarked that he found it a "wonderful book" and "valuable".
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): What city was Feynman abandoned in at his birth?
Ah, so..
