The industrial revolution implemented new working structures and systems. Workers were underpaid while working exhaustively, leading the creation of minimum wages and decent working conditions. With the industrial expansion, the proletarian class grew exponentially, promoting the birth of this huge economical class and all their social influence. During this period some concepts such as utilitarianism and socialism were born.
Answer: was held on 26 April 1920 at the Smithsonian Museum of Natural History, between the astronomers Harlow Shapley and Heber Curtis. It concerned the nature of so-called spiral nebulae and the size of the universe; Shapley believed that distant nebulae were relatively small and lay within the outskirts of Earth's home galaxy, while Curtis held that they were in fact independent galaxies, implying that they were exceedingly large and distant.
The two scientists first presented independent technical papers about "The Scale of the Universe" during the day and then took part in a joint discussion that evening. Much of the lore of the Great Debate grew out of two papers published by Shapley and by Curtis in the May 1921 issue of the Bulletin of the National Research Council. The published papers each included counter arguments to the position advocated by the other scientist at the 1920 meeting.
In the aftermath of the public debate, scientists have been able to verify individual pieces of evidence from both astronomers, but on the main point of the existence of other galaxies, Curtis has been proven correct.

Answer: be the first thing you notice, whether you are examining dinnerware, vases or decorative pieces. The art of making porcelain china began in the country that lent its name to these items well over 1,000 years ago. Fine china -- bone or porcelain -- weighs substantially less than an equivalent stoneware or earthenware piece. While newer china pieces are typically dishwasher safe, for older items, don't put them into the dishwasher if you want them to last.
Ceramic Types
China -- a catchall word used to describe most any ceramic piece, dinnerware or decorative item -- can be categorized into four basic types: bone china, porcelain china, stoneware and earthenware. The first two represent fine china, while the latter two are typically associated with everyday dinnerware, crocks, jugs or decorative pieces. The materials used, the firing processes, the decorative glazes and finishing touches mark the difference between fine china and functional china.
Inner Light
Place your hand behind a plate of fine bone china -- the highest quality china made -- and you can see its shadow through it. Light passes through bone china, even more translucent than china made from porcelain clays and materials. Bone china, the English answer to Chinese porcelain, has a glasslike quality to it, is very light and thin, and is kiln-fired at even higher temperatures than porcelain china. Bone china seems to glow with an inner light; though seemingly fragile, it is very strong.
