Answer 1

GUTENBERG, JOHANNES - PRINTING PRESS WITH MOVABLE TYPE
Johannes Gutenberg (the late 1300's-1468) was a German craftsman, inventor, and printer who invented the first printing press with movable type in 1450. This invention revolutionized printing, making it simpler and more affordable. Gutenberg produced dies (molds) for easily producing individual pieces of metal type that could be made, assembled, and later reused. Gutenberg's new press could print a page every three minutes. This made printed material available to the masses for the first time in history. Religious materials were the majority of the early printed materials. The use of printing presses began the standardization of spelling.


Leonardo da Vinci (1452-1519) was an Italian inventor, artist, and scientist. Da Vinci had an interest in engineering and made detailed sketches of the airplane, the helicopter (and other flying machines), the parachute, the submarine, the armored car, the ballista (a giant crossbow), rapid-fire guns, the centrifugal pump (designed to drain wet areas, like marshes), ball bearings, the worm gear (a set of gears in which many teeth make contact at once, reducing the strain on the teeth, allowing more pressure to be put on the mechanism).

The caravel (also spelled carvel) is a light sailing ship that that was developed by the Portuguese in the late 1400's, and was used for the next 300 years. The Portuguese developed this ship to help them explore the African coast. Columbus also used this type to discover the West Indies or "America". This type was also used by the Spanish to carry troops in 1588 when the Spanish Armada was sent against England.

Martin Behaim (1459-1537) was a German mapmaker, navigator, and merchant. Behaim made the earliest globe, called the "Nürnberg Terrestrial Globe". It was made during the years 1490-1492; the painter Georg Glockendon helped in the project. Behaim had previously sailed to Portugal as a merchant (in 1480). He had advised King John II on matters concerning navigation. He accompanied the Portuguese explorer Diogo Cam (Cão) on a 1485-1486 voyage to the coast of West Africa; during this trip, the mouth of the Congo River was discovered. After returning to Nürnberg in 1490, Behaim began construction of his globe (which was very inaccurate as compared to other maps from that time, even in the areas in which Behaim had sailed). It was once thought that Behaim's maps might have influenced Columbus and Magellan; this is now discounted. Behaim may have also developed an astrolabe. Behaim's globe is now in the German National Museum in Nürnberg.

The anemometer is a device that measures the speed of the wind (or other airflow, like in a wind tunnel). The first anemometer, a disc placed perpendicular to the wind, was invented in 1450 by the Italian architect Leon Battista Alberti.

Answer 2

I think the first person describe it good enough, but I think you should also add that the printing press helped with the spread of the Protestant Reformation. Martin Luther and 95 Theses
