humanists were chiefly interested in the problem of the ancient church and the question of what constituted original Christianity. Two factors operated to accelerate the spread of Renaissance culture after 1450: growing economic prosperity and the printing press. Prosperity -- the result of peace and the decline of famine and the plague -- led to the founding of schools and colleges. In these schools the sons of gentlemen and nobles would receive a humanistic education imported from Italy. The purpose

The Printing Press It is argued that the printing press is one of the most significant inventions of all time ranked alongside the wheel and the plow (Johannes Gutenberg and‚ 2009). The man credited with its invention is Johannes Gutenberg‚ born of Mainz‚ Germany around 1400 (Childress‚ 2008). Johannes began his work with the printing press around 1430 and developed his first prototype somewhere around the mid-15th century. As with most inventions‚ Gutenberg’s press had precedents in history

Stereolithography is a printing process that enables a tangible 3-dimensional object to be created from digital data.(A Brief) 3D printing was invented by Charles Hull in 1984.(A Brief) The concept came from the Ink Jet Printer in 1984.(A Brief) 3D printing is steam lining by saving time and money when turning concepts into prototypes and then into final products (Mehta) There are 3 steps‚ Modeling‚ printing then adding color and smoothing (Matt).

is 3D printing the most important opportunity facing manufacturers in the United Kingdom? (40 marks) Manufacturing to the economy of the United Kingdom is worth £213 billion‚ whilst simultaneously representing 11% of the total country’s economy. It is both in the interest of the United Kingdom’s government and individual manufacturing business that these figures continue to increase. For this to happen‚ there are a range of opportunities waiting to be exploited‚ ranging from 3D printing‚ green technologies

Killer Whale Introduction The killer whale (Orcinus orca)‚ also referred to as the orca whale or orca‚ and less commonly as the blackfish‚ is a toothed whale belonging to the oceanic dolphin family. Killer whales are found in all oceans‚ from the frigid Arctic and Antarctic regions to tropical seas. Killer whales as a species have a diverse diet‚ although individual populations often specialize in particular types of prey. Some feed exclusively on fish‚ while others hunt marine mammals such as sea

Saving the Whales When I think about the ocean‚ I think about all the animals that live in it‚ including the whales. Whale hunting has been going on for decades. These huge ships go out into the sea and capture whales; they claim they are capturing them for research. What kind of research exactly? I do not know. One article I read on the issue said that the whales used for the research end up being a meal more times than not. In other words‚ they capture the whales‚ do their “research” and then

A. Swimming. 1. In general‚ beluga whales are slow swimmers. They commonly swim about 3 to 9 kph (1.9-5.6 mph). They are‚ however‚ capable of sustaining a maximum speed of 22 kph (13.6 mph) for as long as 15 minutes (Nowak‚ 1991; Ridgway and Harrison‚ 1981). 2. Belugas can swim forward and backward (Nowak‚ 1991). 3. Beluga whales often swim at depths barely covering their bodies (Ridgway and Harrison‚ 1981). B. Diving. 1. Beluga whales typically don’t dive very deep‚ usually to

Organ Printing Bioprinting is a relatively new field that involves creating living tissue with a three dimensional printer. The process of 3D printing is becoming increasingly popular in many fields as it allows for the direct digital manufacture of a wide variety of plastic and metal items. While this technology is revolutionizing by itself‚ it is now being applied to the field of tissue engineering to produce biological tissue in the form of bioprinters. These devices artificially construct living
