The JEDEC EIA370 transistor device numbers usually start with "2N", indicating a three-terminal device (dual-gate field-effect transistors are four-terminal devices, so begin with 3N), then a 2, 3 or 4-digit sequential number with no significance as to device properties (although early devices with low numbers tend to be germanium). For example, 2N3055 is a silicon npn power transistor, 2N1301 is a pnp germanium switching transistor. A letter suffix (such as "A") is sometimes used to indicate a newer variant, but rarely gain groupings.
What are most modern devices made from?
A: unanswerable

The use of uranium in its natural oxide form dates back to at least the year 79 CE, when it was used to add a yellow color to ceramic glazes. Yellow glass with 1% uranium oxide was found in a Roman villa on Cape Posillipo in the Bay of Naples, Italy, by R. T. Gunther of the University of Oxford in 1912. Starting in the late Middle Ages, pitchblende was extracted from the Habsburg silver mines in Joachimsthal, Bohemia (now Jachymov in the Czech Republic), and was used as a coloring agent in the local glassmaking industry. In the early 19th century, the world's only known sources of uranium ore were these mines.
What institution did R.T. Gunther belong to?
A: the University of Oxford

Since the first Premier League season in 199293, 14 different players from 10 different clubs have won or shared the top scorers title. Thierry Henry won his fourth overall scoring title by scoring 27 goals in the 200506 season. Andrew Cole and Alan Shearer hold the record for most goals in a season (34) for Newcastle and Blackburn respectively. Ryan Giggs of Manchester United holds the record for scoring goals in consecutive seasons, having scored in the first 21 seasons of the league.
How many goals did Thierry Henry score when he won his fifth scoring title?

This view of 'diplomatic drift' as the cause of the war was first popularised by A. W, Kinglake, who portrayed the British as victims of newspaper sensationalism and duplicitous French and Ottoman diplomacy. More recently, the historians Andrew Lambert and Winfried Baumgart have argued that, first, Britain was following a geopolitical strategy in aiming to destroy a fledgling Russian Navy which might challenge the Royal Navy for control of the seas, and second that the war was a joint European response to a century of Russian expansion not just southwards but also into western Europe.
Who made the view of diplomatic drift popular?
A:
A. W, Kinglake
