On his return to Nuremberg in 1495, Durer opened his own workshop (being married was a requirement for this). Over the next five years his style increasingly integrated Italian influences into underlying Northern forms. Durer's father died in 1502, and his mother died in 1513. His best works in the first years of the workshop were his woodcut prints, mostly religious, but including secular scenes such as The Men's Bath House (ca. 1496). These were larger and more finely cut than the great majority of German woodcuts hitherto, and far more complex and balanced in composition. It is now thought unlikely that Durer cut any of the woodblocks himself; this task would have been performed by a specialist craftsman. However, his training in Wolgemut's studio, which made many carved and painted altarpieces and both designed and cut woodblocks for woodcut, evidently gave him great understanding of what the technique could be made to produce, and how to work with block cutters. Durer either drew his design directly onto the woodblock itself, or glued a paper drawing to the block. Either way, his drawings were destroyed during the cutting of the block.

Answer: How many years after Durer's workshop opened did his father die?

Earths magnetic field helps protect Earth and its organisms. It protects us from harmful particles given off by the sun. Most of the particles are attracted to the north and south magnetic poles. This is where Earths magnetic field is strongest. This is also where relatively few organisms live. Another benefit of Earths magnetic field is its use for navigation. People use compasses to detect Earths magnetic north pole. Knowing this helps them tell direction. Many animals have natural 'compasses' that work just as well. Birds like the garden warbler in Figure 1.36 use Earths magnetic field. They use it to guide their annual migrations. Recent research suggests that warblers and other migrating birds have structures in their eyes. These structures let them see Earths magnetic field as a visual pattern.

Answer: What works to detect Earth's magnetic north pole, telling direction besides people's compasses?

The only home Hamilton ever owned was a Federal style mansion designed by John McComb Jr., which he built on his 32-acre country estate in Hamilton Heights in upper Manhattan. He named the house, which was completed in 1802, the "Grange" after his grandfather Alexander's estate in Ayrshire, Scotland. The house remained in the family until 1833 when his widow sold it to Thomas E. Davis, a British born real estate developer, for $25,000. Part of the proceeds were used by Eliza to purchase a new townhouse from Davis (Hamilton-Holly House) in Greenwich Village with her son Alexander. The Grange, first moved from its original location in 1889, was moved again in 2008 to a spot in St. Nicholas Park on land that was once part of the Hamilton estate, in Hamilton Heights, a neighborhood in upper Manhattan. The historic structure was restored to its original 1802 appearance in 2011, and is maintained by the National Park service as Hamilton Grange National Memorial. Alexander Hamilton served as one of the first trustees of the Hamilton-Oneida Academy in New York state. Later the Academy received a college charter in 1812, and the school was formally renamed Hamilton College.Columbia University, Hamilton's alma mater, has official memorials to Hamilton on its campus in New York City. The college's main classroom building for the humanities is Hamilton Hall, and a large statue of Hamilton stands in front of it. The university press has published his complete works in a multivolume letterpress edition. Columbia University's student group for ROTC cadets and Marine officer candidates is named the Alexander Hamilton Society.

Answer: When was the Grange originally built, and when was it sold?

Surely, you have noticed the tall poles along the roadside. Do you know what is on top of those poles? Thats right, wires that carry electric current. These wires carry electric current to your home. But what is electric current? Electric current is actually the flow of electrons. You may recall, an electron is the outer-most particle in an atom. They have a negative charge. Electricity is the continuous flow of these particles. Electrons are able to move through wires. Their speed can even be measured. The SI unit for electric current (or speed) is the ampere (A). Ampere is often shortened to amp. Electric current may flow in just one direction, or it may keep reversing direction. Direct current (DC) flows in only one direction. Direct current is what is used in devices like flashlights. Alternating current (AC) flows in two directions. This is the type of current that flows into your home through wires.

Where do the wires carry electric current?
